Sec. 571.208 Standard No. 208; Occupant crash protection.
S1. Scope. This standard specifies performance requirements for the
protection of vehicle occupants in crashes.
S2. Purpose. The purpose of this standard is to reduce the number of
deaths of vehicle occupants, and the severity of injuries, by specifying
vehicle crashworthiness requirements in terms
[[Page 481]]
of forces and accelerations measured on anthropomorphic dummies in test
crashes, and by specifying equipment requirements for active and passive
restraint systems.
S3. Application. (a) This standard applies to passenger cars,
multipurpose passenger vehicles, trucks, and buses. In addition, S9,
Pressure vessels and explosive devices, applies to vessels designed to
contain a pressurized fluid or gas, and to explosive devices, for use in
the above types of motor vehicles as part of a system designed to
provide protection to occupants in the event of a crash.
(b) Notwithstanding any language to the contrary, any vehicle
manufactured after March 19, 1997, and before September 1, 2006, that is
subject to a dynamic crash test requirement conducted with unbelted
dummies may meet the requirements specified in S5.1.2(a)(1),
S5.1.2(a)(2), or S13 instead of the applicable unbelted requirement,
unless the vehicle is certified to meet the requirements specified in
S14.5, S15, S17, S19, S21, S23, and S25.
(c) For vehicles which are certified to meet the requirements
specified in S13 instead of the otherwise applicable dynamic crash test
requirement conducted with unbelted dummies, compliance with S13 shall,
for purposes of Standards No. 201, 203 and 209, be deemed as compliance
with the unbelted frontal barrier requirements of S5.1.2.

(2) The maximum calculated HIC36 value shall not exceed
1,000.
(b)(1) For any two points in time, t1 and t2,
during the event which are separated by not more than a 15 millisecond
time interval and where t1 is less than t2, the
head injury criterion (HIC15) shall be determined using the
resultant head acceleration at the center of gravity of the dummy head,
ar, expressed as a multiple of g (the acceleration of
gravity) and shall be calculated using the expression:
[GRAPHIC] [TIFF OMITTED] TR12MY00.004
(2) The maximum calculated HIC15 value shall not exceed
700.
S6.3 The resultant acceleration calculated from the output of the
thoracic instrumentation shown in drawing 78051.218, revision R
incorporated by reference in part 572, subpart E of this chapter shall

(b) Compressive deflection of the sternum relative to the spine
shall not exceed 63 mm (2.5 in).
S6.5 The force transmitted axially through each upper leg shall not
exceed 2250 pounds.
S6.6 Neck injury. When measuring neck injury, each of the following
injury criteria shall be met.
(a) Nij.
(1) The shear force (Fx), axial force (Fz), and bending moment (My)
shall be measured by the dummy upper neck load cell for the duration of
the crash event as specified in S4.11. Shear force, axial force, and
bending moment shall be filtered for Nij purposes at SAE J211/1 rev. Mar
95 Channel Frequency Class 600 (see S4.7).
(2) During the event, the axial force (Fz) can be either in tension
or compression while the occipital condyle
[[Page 502]]
bending moment (Mocy) can be in either flexion or extension. This
results in four possible loading conditions for Nij: tension-extension
(Nte), tension-flexion (Ntf), compression-extension (Nce), or
compression-flexion (Ncf).
(3) When calculating Nij using equation S6.6(a)(4), the critical
values, Fzc and Myc, are:
(i) Fzc = 6806 N (1530 lbf) when Fz is in tension
(ii) Fzc = 6160 N (1385 lbf) when Fz is in compression
(iii) Myc = 310 Nm (229 lbf-ft) when a flexion moment exists at the
occipital condyle
(iv) Myc = 135 Nm (100 lbf-ft) when an extension moment exists at the
occipital condyle.
(4) At each point in time, only one of the four loading conditions
occurs and the Nij value corresponding to that loading condition is
computed and the three remaining loading modes shall be considered a
value of zero. The expression for calculating each Nij loading condition
is given by:
Nij = (Fz/Fzc) + (Mocy/Myc)
(5) None of the four Nij values shall exceed 1.0 at any time during
the event.
(b) Peak tension. Tension force (Fz), measured at the upper neck
load cell, shall not exceed 4170 N (937 lbf) at any time.
(c) Peak compression. Compression force (Fz), measured at the upper
neck load cell, shall not exceed 4000 N (899 lbf) at any time.
S6.7 Unless otherwise indicated, instrumentation for data
acquisition, data channel frequency class, and moment calculations are
the same as given for the 49 CFR Part 572, Subpart E Hybrid III test
dummy.

seat belt parts (the seat belt latchplate, the buckle, or the seat belt
webbing) on top of or above the seat cushion under normal conditions
(i.e., conditions other than when belt hardware is intentionally pushed
behind the seat by a vehicle occupant). In addition, the remaining two
seat belt parts must be accessible under normal conditions.
(b) The requirements of S7.4.6.1(a) do not apply to: (1) seats whose
seat cushions are movable so that the seat back serves a function other
than seating, (2) seats which are removable, or (3) seats which are
movable so that the space formerly occupied by the seat can be used for
a secondary function.
S7.4.6.2 The buckle and latchplate of a manual seat belt assembly
subject to S7.4.6.1 shall not pass through the guides or conduits
provided for in S7.4.6.1 and fall behind the seat when the events listed
below occur in the order specified: (a) The belt is completely retracted
or, if the belt is nonretractable, the belt is unlatched; (b) the seat
is moved to any position to which it is designed to be adjusted; and (c)
the seat back, if foldable, is folded forward as far as possible and
then moved backward into position. The inboard receptacle end of a seat
belt assembly installed at a front outboard designated seating position
shall be accessible with the center arm rest in any position to which it
can be adjusted (without having to move the armrest).
S8. Test conditions.
S8.1 General conditions. The following conditions apply to the
frontal, lateral, and rollover tests. Except for S8.1.1(d), the
following conditions apply to the alternative unbelted sled test set
forth in S13 from March 19, 1997 until September 1, 2001.
S8.1.1 Except as provided in paragraph (c) of S8.1.1, the vehicle,
including test devices and instrumentation, is loaded as follows:
(a) Passenger cars. A passenger car is loaded to its unloaded
vehicle weight plus its rated cargo and luggage capacity weight, secured
in the luggage area, plus the weight of the necessary anthropomorphic
test devices.
(b) Multipurpose passenger vehicles, trucks, and buses. A
multipurpose passenger vehicle, truck, or bus is loaded to its unloaded
vehicle weight plus 300 pounds or its rated cargo and luggage
[[Page 508]]
capacity weight, whichever is less, secured in the load carrying area
and distributed as nearly as possible in proportion to its gross axle
weight ratings, plus the weight of the necessary anthropomorphic test
devices. For the purposes of Sec. 8.1.1, unloaded vehicle weight does
not include the weight of work-performing accessories. Vehicles are
tested to a maximum unloaded vehicle weight of 5,500 pounds.
(c) Fuel system capacity. With the test vehicle on a level surface,
pump the fuel from the vehicle's fuel tank and then operate the engine
until it stops. Then, add Stoddard solvent to the test vehicle's fuel
tank in an amount which is equal to not less than 92 and not more than
94 percent of the fuel tank's usable capacity stated by the vehicle's
manufacturer. In addition, add the amount of Stoddard solvent needed to
fill the entire fuel system from the fuel tank through the engine's
induction system.
(d) Vehicle test attitude. Determine the distance between a level
surface and a standard reference point on the test vehicle's body,
directly above each wheel opening, when the vehicle is in its ``as
delivered'' condition. The ``as delivered'' condition is the vehicle as
received at the test site, with 100 percent of all fluid capacities and
all tires inflated to the manufacturer's specifications as listed on the
vehicle's tire placard. Determine the distance between the same level
surface and the same standard reference points in the vehicle's ``fully
loaded condition.'' The ``fully loaded condition'' is the test vehicle
loaded in accordance with S8.1.1 (a) or (b), as applicable. The load
placed in the cargo area shall be center over the longitudinal
centerline of the vehicle. The pretest vehicle attitude shall be equal
to either the as delivered or fully loaded attitude or between the as
delivered attitude and the fully loaded attitude.
S8.1.2 Adjustable seats are in the adjustment position midway
between the forwardmost and rearmost positions, and if separately
adjustable in a vertical direction, are at the lowest position. If an
adjustment position does not exist midway between the forwardmost and
rearmost positions, the closest adjustment position to the rear of the
midpoint is used.
S8.1.3 Place adjustable seat backs in the manufacturer's nominal
design riding position in the manner specified by the manufacturer.
Place any adjustable anchorages at the manufacturer's nominal design
position for a 50th percentile adult male occupant. Place each
adjustable head restraint in its highest adjustment position. Adjustable
lumbar supports are positioned so that the lumbar support is in its
lowest adjustment position.
S8.1.4 Adjustable steering controls are adjusted so that the
steering wheel hub is at the geometric center of the locus it describes
when it is moved through its full range of driving positions.
S8.1.5 Movable vehicle windows and vents are placed in the fully
closed position, unless the vehicle manufacturer chooses to specify a
different adjustment position prior to the time it certifies the
vehicle.
S8.1.6 Convertibles and open-body type vehicles have the top, if
any, in place in the closed passenger compartment configuration.
S8.1.7 Doors are fully closed and latched but not locked.
S8.1.8 Anthropomorphic test dummies.

occupant protection systems manufactured pursuant to applicable portions
of S4.1.2, S4.1.3, and S4.1.4 of this standard shall conform to the
requirements of subpart E of part 572 of this chapter.
S8.1.8.2 Each test dummy is clothed in a form fitting cotton
stretch short sleeve shirt with above-the-elbow sleeves and above-the-
knee length pants. The weight of the shirt or pants shall not exceed
0.25 pounds each. Each foot of the test dummy is equipped with a size
11XW shoe which meets the configuration size, sole, and heel thickness
specifications of MIL-S 13192 change ``P'' and whose weight is
1.250.2 pounds.
S8.1.8.3 Limb joints are set at 1g, barely restraining the weight
of the limb when extended horizontally. Leg joints are adjusted with the
torso in the supine position.
[[Page 509]]
S8.1.8.4 Instrumentation does not affect the motion of the dummies
during impact or rollover.
S8.1.8.5 The stabilized test temperature of the test dummy is at
any temperature level between 69 degrees F and 72 degrees F, inclusive.
S8.2 Lateral moving barrier crash test conditions. The following
conditions apply to the lateral moving barrier crash test.
S8.2.1 The moving barrier, including the impact surface, supporting
structure, and carriage, weighs 4,000 pounds.
S8.2.2 The impact surface of the barrier is a vertical, rigid, flat
rectangle, 78 inches wide and 60 inches high, perpendicular to its
direction of movement, with its lower edge horizontal and 5 inches above
the ground surface.
S8.2.3 During the entire impact sequence the barrier undergoes no
significant amount of dynamic or static deformation, and absorbs no
significant portion of the energy resulting from the impact, except for
energy that results in translational rebound movement of the barrier.
S8.2.4 During the entire impact sequence the barrier is guided so
that it travels in a straight line, with no significant lateral,
vertical or rotational movement.
S8.2.5 The concrete surface upon which the vehicle is tested is
level, rigid and of uniform construction, with a skidnumber of 75 when
measured in accordance with American Society for Testing and Materials
Method E-274-65T at 40 m.p.h., omitting water delivery as specified in
paragraph 7.1 of that method.
S8.2.6 The tested vehicle's brakes are disengaged and the
transmission is in neutral.
S8.2.7 The barrier and the test vehicle are positioned so that at
impact--
(a) The vehicle is at rest in its normal attitude;
(b) The barrier is traveling in a direction perpendicular to the
longitudinal axis of the vehicle at 20 m.p.h.; and
(c) A vertical plane through the geometric center of the barrier
impact surface and perpendicular to that surface passes through the
driver's seating reference point in the tested vehicle.
S8.3 Rollover test conditions. The following conditions apply to
the rollover test.
S8.3.1 The tested vehicle's brakes are disengaged and the
transmission is in neutral.
S8.3.2 The concrete surface on which the test is conducted is
level, rigid, of uniform construction, and of a sufficient size that the
vehicle remains on it throughout the entire rollover cycle. It has a
skid number of 75 when measured in accordance with American Society for
Testing and Materials Method E-274-65T at 40 m.p.h. omitting water
delivery as specified in paragraph 7.1 of that method.
S8.3.3 The vehicle is placed on a device, similar to that
illustrated in Figure 2, having a platform in the form of a flat, rigid
plane at an angle of 23 deg. from the horizontal. At the lower edge of
the platform is an unyielding flange, perpendicular to the platform with
a height of 4 inches and a length sufficient to hold in place the tires
that rest against it. The intersection of the inner face of the flange
with the upper face of the platform is 9 inches above the rollover
surface. No other restraints are used to hold the vehicle in position
during the deceleration of the platform and the departure of the
vehicle.
S8.3.4 With the vehicle on the test platform, the test devices
remain as nearly as possible in the posture specified in S8.1.
S8.3.5 Before the deceleration pulse, the platform is moving
horizontally, and perpendicularly to the longitudinal axis of the
vehicle, at a constant speed of 30 m.p.h. for a sufficient period of
time for the vehicle to become motionless relative to the platform.
S8.3.6 The platform is decelerated from 30 to 0 m.p.h. in a
distance of not more than 3 feet, without change of direction and
without transverse or rotational movement during the deceleration of the
platform and the departure of the vehicle. The deceleration rate is at
least 20g for a minimum of 0.04 seconds.
S8.4 Frontal test condition. If the vehicle is equipped with a
cutoff device permitted by S4.5.4 of this standard, the device is
deactivated.

pressurized shall conform to the requirements of Secs. 178.65-2, 178.65-
6(b), 178.65-7, 178.65-9 (a) and (b), and 178.65-10 of this title. It
shall not leak or evidence visible distortion when tested in accordance
with Sec. 178.65-11(a) of this title and shall not fail in any of the
ways enumerated in Sec. 178.65-11(b) of this title when hydrostatically
tested to destruction. It shall not crack when flattened in accordance
with Sec. 178.65-12(a) of this title to the limit specified in
Sec. 178.65-12(a)(4) of this title.
S9.2 Explosive devices. An explosive device shall not exhibit any
of the characteristics prohibited by Sec. 173.51 of this title. All
explosive material shall be enclosed in a structure that is capable of
containing the explosive energy without sudden release of pressure
except through overpressure relief devices or parts designed to release
the pressure during actuation.
S10. Test dummy positioning procedures.
S10.1 Head. The transverse instrumentation platform of the head
shall be level within \1/2\ degree. To level the head of the test dummy,
the following sequences must be followed. First, adjust the position of
the H point within the limits set forth in S10.4.2.1 to level the
transverse instrumentation platform of the head of the test dummy. If
the transverse instrumentation platform of the head is still not level,
then adjust the pelvic angle of the test dummy within the limits
specified in S10.4.2.2 of this standard. If the transverse
instrumentation platform of the head is still not level, then adjust the
neck bracket of the dummy the minimum amount necessary from the non-
adjusted ``0'' setting to ensure that the transverse instrumentation
platform of the head is horizontal within \1/2\ degree. The test dummy
shall remain within the limits specified in S10.4.2.1 and S10.4.2.2.
after any adjustment of the neck bracket.
S10.2 Upper Arms.
S10.2.1 The driver's upper arms shall be adjacent to the torso with
the centerlines as close to a vertical plane as possible.
S10.2.2 The passenger's upper arms shall be in contact with the
seat back and the sides of the torso.
S10.3 Hands.
S10.3.1 The palms of the drivers test dummy shall be in contact
with the outer part of the steering wheel rim at the rim's horizontal
centerline. The thumbs shall be over the steering wheel rim and shall be
lightly taped to the steering wheel rim so that if the hand of the test
dummy is pushed upward by a force of not less than 2 pounds and not more
than 5 pounds, the tape shall release the hand from the steering wheel
rim.
S10.3.2 The palms of the passenger test dummy shall be in contact
with the outside of the thigh. The little finger shall be in contact
with the seat cushion.
S10.4 Torso.
S10.4.1 Upper Torso.
S10.4.1.1 In vehicles equipped with bench seats, the upper torso of
the driver and passenger test dummies shall rest against the seat back.
The midsagittal plane of the driver dummy shall be vertical and parallel
to the vehicle's longitudinal centerline, and pass through the center of
the steering wheel rim. The midsagittal plane of the passenger dummy
shall be vertical and parallel to the vehicle's longitudinal centerline
and the same distance from the vehicle's longitudinal centerline as the
midsagittal plane of the driver dummy.
S10.4.1.2 In vehicles equipped with bucket seats, the upper torso
of the driver and passenger test dummies shall rest against the seat
back. The midsagittal plane of the driver and the passenger dummy shall
be vertical and shall coincide with the longitudinal centerline of the
bucket seat.
S10.4.2 Lower Torso.
S10.4.2.1 H-point. The H-points of the driver and passenger test
dummies shall coincide within \1/2\ inch in the vertical dimension and
\1/2\ inch in the horizontal dimension of a point \1/4\ inch below the
position of the H-point determined by using the equipment and procedures
specified in SAE J826 (APR 1980) except that the length of the lower leg
and thigh segments of the H-point machine shall be adjusted to 16.3 and
15.8 inches, respectively, instead of
[[Page 511]]
the 50th percentile values specified in Table 1 of SAE J826.
S10.4.2.2 Pelvic angle. As determined using the pelvic angle gage
(GM drawing 78051-532, incorporated by reference in part 572, subpart E
of this chapter) which is inserted into the H-point gaging hole of the
dummy, the angle measured from the horizontal on the three inch flat
surface of the gage shall be 22\1/2\ degrees plus or minus 2\1/2\
degrees.
S10.5 Legs. The upper legs of the driver and passenger test dummies
shall rest against the seat cushion to the extent permitted by placement
of the feet. The initial distance between the outboard knee clevis
flange surfaces shall be 10.6 inches. To the extent practicable, the
left leg of the driver dummy and both legs of the passenger dummy shall
be in vertical longitudinal planes. To the extent practicable, the right
leg of the driver dummy shall be in a vertical plane. Final adjustment
to accommodate the placement of feet in accordance with S10.6 for
various passenger compartment configurations is permitted.
S10.6 Feet.
S10.6.1 Driver's position.
S10.6.1.1 If the vehicle has an adjustable accelerator pedal, adjust
it to the full forward position. Rest the right foot of the test dummy
on the undepressed accelerator pedal with the rearmost point of the heel
on the floor pan in the plane of the pedal. If the foot cannot be placed
on the accelerator pedal, set it initially perpendicular to the lower
leg and then place it as far forward as possible in the direction of the
pedal centerline with the rearmost point of the heel resting on the
floor pan. If the vehicle has an adjustable accelerator pedal and the
right foot is not touching the accelerator pedal when positioned as
above, move the pedal rearward until it touches the right foot. If the
accelerator pedal still does not touch the foot in the full rearward
position, leave the pedal in that position.
S10.6.1.2 Place the left foot on the toeboard with the rearmost
point of the heel resting on the floor pan as close as possible to the
point of intersection of the planes described by the toeboard and the
floor pan and not on the wheelwell projection. If the foot cannot be
positioned on the toeboard, set it initially perpendicular to the lower
leg and place it as far forward as possible with the heel resting on the
floor pan. If necessary to avoid contact with the vehicle's brake or
clutch pedal, rotate the test dummy's left foot about the lower leg. If
there is still pedal interference, rotate the left leg outboard about
the hip the minimum distance necessary to avoid the pedal interference.
For vehicles with a foot rest that does not elevate the left foot above
the level of the right foot, place the left foot on the foot rest so
that the upper and lower leg centerlines fall in a vertical plane.
S10.6.2 Passenger's position.
S10.6.2.1 Vehicles with a flat floor pan/toeboard. Place the right
and left feet on the vehicle's toeboard with the heels resting on the
floor pan as close as possible to the intersection point with the
toeboard. If the feet cannot be placed flat on the toeboard, set them
perpendicular to the lower leg centerlines and place them as far forward
as possible with the heels resting on the floor pan.
S10.6.2.2 Vehicles with wheelhouse projections in passenger
compartment. Place the right and left feet in the well of the floor pan/
toeboard and not on the wheelhouse projection. If the feet cannot be
placed flat on the toeboard, initially set them perpendicular to the
lower leg centerlines and then place them as far forward as possible
with the heels resting on the floor pan.
S10.7 Test dummy positioning for latchplate access. The reach
envelopes specified in S7.4.4 of this standard are obtained by
positioning a test dummy in the driver's or passenger's seating position
and adjusting that seating position to its forwardmost adjustment
position. Attach the lines for the inboard and outboard arms to the test
dummy as described in Figure 3 of this standard. Extend each line
backward and outboard to generate the compliance arcs of the outboard
reach envelope of the test dummy's arms.
S10.8 Test dummy positioning for belt contact force. To determine
compliance with S7.4.3 of this standard, position the test dummy in the
vehicle in accordance with S10.1 through S10.6 of
[[Page 512]]
this standard and adjust the seating position in accordance with S8.1.2
and S8.1.3 of this standard. Pull the belt webbing three inches from the
test dummy's chest and release until the webbing is within one inch of
the test dummy's chest and measure the belt contact force.
S10.9 Manual belt adjustment for dynamic testing. With the test
dummy positioned in accordance with S10.1 through S10.6 of this standard
and the seating position adjusted in accordance with S8.1.2 and S8.1.3
of this standard, place the Type 2 manual belt around the test dummy and
fasten the latch. Remove all slack from the lap belt portion. Pull the
upper torso webbing out of the retractor and allow it to retract; repeat
this four times. Apply a 2 to 4 pound tension load to the lap belt. If
the belt system is equipped with a tension-relieving device, introduce
the maximum amount of slack into the upper torso belt that is
recommended by the vehicle manufacturer in the vehicle's owner's manual.
If the belt system is not equipped with a tension-relieving device,
allow the excess webbing in the upper torso belt to be retracted by the
retractive force of the retractor.

from the inflatable restraint requirement, a vehicle manufacturer must
demonstrate in its application that there has been a disruption in the
supply of one or more inflatable restraint system components, or a
disruption in the use and installation by the manufacturer of any such
component due to unavoidable events not under the control of the
manufacturer, which will prevent a manufacturer from meeting its
anticipated production volume of vehicles with inflatable restraint
systems.
S12.4 Exemption applications--General requirements. Each
application for a temporary exemption from the inflatable restraint
requirements must--
(a) Be written in the English language;
(b) Be submitted in three copies to: Administrator, National Highway
Traffic Safety Administration, 400 Seventh Street, SW., Washington, DC

installation of missing inflatable restraint systems;
(g) A proposed reasonable period of time after the disruption in the
supply of inflatable restraint system components is corrected that the
manufacturer estimates will ensure a sufficient quantity of components
for both anticipated production and retrofit of those vehicles for which
a temporary exemption is requested in the application, so that the
vehicle manufacturer can recall those vehicles for which a temporary
exemption is requested and install inflatable restraint systems in them,
together with a demonstration of why the manufacturer believes this
proposed period of time is reasonable for completing this recall, or an
explanation of why it is not possible to provide such an estimate;
(h) A proposed date for termination of the exemption;
(i) A proposed date by which all exempted vehicles will have been
recalled and had inflatable restraints installed (assuming owners
returned their vehicles in a timely matter in response to a first notice

provide such an estimate.
S12.6 Processing an application for a temporary exemption. (a)
NHTSA will process any application for temporary exemption that contains
the information specified in S12.4 and S12.5. If an application fails to
provide the information specified in S12.4 and S12.5, NHTSA will not
process the application, but will advise the manufacturer of the
information that must be provided if the agency is to process the
application.
(b) Notice of each application for temporary exemption shall be
published in the Federal Register.
(c) NHTSA will issue its decision to grant or deny the requested
temporary exemption not later than 15 days after the agency receives a
complete petition, as defined in paragraph (a). However, a failure to
issue a decision within this time does not result in a grant of the
petition.
(d) Notice of each decision to grant or deny a temporary exemption,
and the reasons for granting or denying it, will be published in the
Federal Register.
(e) The Administrator may attach such conditions as he or she deems
appropriate to a temporary exemption, including but not limited to
requiring manufacturers to provide progress reports at specified times
(including, as appropriate and to the extent possible, estimate of dates
and times concerning when a supply disruption will be corrected and when
recall will take place) and requiring manufacturers to take specific
steps to ensure that as many exempted vehicles as possible will be
returned for installation of missing inflatable restraint systems.
(f) Unless a later effective date is specified in a notice
announcing an agency decision to grant a temporary exemption, a
temporary exemption from the inflatable restraint requirement will
become effective upon the date the decision is issued.

S13 Alternative unbelted test available, under S3(b) of this
standard, for certain vehicles manufactured before September 1, 2006.
S13.1 Instrumentation for Impact Test--Part 1--Electronic
Instrumentation. Under the applicable conditions of S8, mount the
vehicle on a dynamic test platform at the vehicle attitude set forth in
S13.3, so that the longitudinal center line of the vehicle is parallel
to the direction of the test platform travel and so that movement
between the base of the vehicle and the test platform is prevented. The
test platform is instrumented with an accelerometer and data processing
system having a frequency response of 60 channel class as specified in
SAE J211/1 rev. Mar 95 (see S4.7). The accelerometer sensitive axis is
parallel to the direction of test platform travel. The test is conducted
at a velocity change approximating 48 km/h (30 mph) with acceleration of
the test platform such that all points on the crash pulse curve within
the corridor identified in Figure 6 are covered. An inflatable restraint
is to be activated at 20 ms +/-2 ms from the time that 0.5 g is measured
on the dynamic test platform. The test dummy specified in S8.1.8, placed
in each front outboard designated seating position as specified in S10,
excluding S10.7, S10.8, and S10.9, shall meet the injury criteria of
S6.1, S6.2(a), S6.3, S6.4(a), S6.5, and S13.2 of this standard.
S13.2 Neck injury criteria. A vehicle certified to this alternative
test requirement shall, in addition to meeting the criteria specified in
S13.1, meet the following injury criteria for the neck, measured with
the six axis load cell (ref. Denton drawing C-1709) that is mounted
between the bottom of the skull and the top of the neck as shown in
Drawing 78051-218, in the unbelted sled test:
(a) Flexion Bending Moment (calculated at the occipital condyle)--
190 Nm. SAE Class 600.
(b) Extension Bending Moment (calculated at the occipital condyle)--
57 Nm. SAE Class 600.
(c) Axial Tension--3300 peak N. SAE Class 1000.
(d) Axial Compression--4000 peak N. SAE Class 1000.
(e) Fore-and-Aft Shear--3100 peak N. SAE Class 1000.
S13.3 Vehicle test attitude. When the vehicle is in its ``as
delivered'' condition, measure the angle between the driver's door sill
and the horizontal. Mark where the angle is taken on the door sill. The
``as delivered'' condition is the vehicle as received at the test
[[Page 515]]
site, with 100 percent of all fluid capacities and all tires inflated to
the manufacturer's specifications as listed on the vehicle's tire
placard. When the vehicle is in its ``fully loaded'' condition, measure
the angle between the driver's door sill and the horizontal, at the same
place the ``as delivered'' angle was measured. The ``fully loaded''
condition is the test vehicle loaded in accordance with S8.1.1(a) or (b)
of Standard No. 208, as applicable. The load placed in the cargo area
shall be centered over the longitudinal centerline of the vehicle. The
pretest door sill angle, when the vehicle is on the sled, (measured at
the same location as the as delivered and fully loaded condition) shall
be equal to or between the as delivered and fully loaded door sill angle
measurements.
S13.4 Tires and wheels. Remove the tires and wheels.
S13.5. Vehicle Securing. The engine, transmissions, axles, exhaust,
vehicle frame, and vehicle body may be rigidly secured to the vehicle
and/or the sled, and fluids, batteries and unsecured components may be
removed, in order to assure that all points on the crash pulse curve are
within the corridor defined in Figure 6.

(a) Nij.
(1) The shear force (Fx), axial force (Fz), and bending moment (My)
shall be measured by the dummy upper neck load cell for the duration of
the crash event as specified in S4.11. Shear force, axial force, and
bending moment shall be filtered for Nij purposes at SAE J211/1 rev. Mar
95 Channel Frequency Class 600 (see S4.7).
(2) During the event, the axial force (Fz) can be either in tension
or compression while the occipital condyle bending moment (Mocy) can be
in either flexion or extension. This results in four possible loading
conditions for Nij: Tension-extension (Nte), tension-flexion (Ntf),
compression-extension (Nce), or compression-flexion (Ncf).
(3) When calculating Nij using equation S15.3.6(a)(4), the critical
values, Fzc and Myc, are:
(i) Fzc = 4287 N (964 lbf) when Fz is in tension
(ii) Fzc = 3880 N (872 lbf) when Fz is in compression
(iii) Myc = 155 Nm (114 lbf-ft) when a flexion moment exists at the
occipital condyle
(iv) Myc = 67 Nm (49 lbf-ft) when an extension moment exists at the
occipital condyle.
(4) At each point in time, only one of the four loading conditions
occurs and the Nij value corresponding to that loading condition is
computed and the three remaining loading modes shall be considered a
value of zero. The expression for calculating each Nij loading condition
is given by:
Nij = (Fz/Fzc) + (Mocy/Myc)
[[Page 519]]
(5) None of the four Nij values shall exceed 1.0 at any time during
the event.
(b) Peak tension. Tension force (Fz), measured at the upper neck
load cell, shall not exceed 2620 N (589 lbf) at any time.
(c) Peak compression. Compression force (Fz), measured at the upper
neck load cell, shall not exceed 2520 N (566 lbf) at any time.
S15.3.7 Unless otherwise indicated, instrumentation for data
acquisition, data channel frequency class, and moment calculations are
the same as given for the 49 CFR Part 572, Subpart O Hybrid III 5th
percentile female test dummy.
S16. Test procedures for rigid barrier test requirements using 5th
percentile adult female dummies.
S16.1 General provisions. Crash testing to determine compliance with
the requirements of S15 of this standard is conducted as specified in
the following paragraphs (a) and (b).
(a) Belted test. Place a 49 CFR Part 572 Subpart O 5th percentile
adult female test dummy at each front outboard seating position of a
vehicle, in accordance with the procedures specified in S16.3 of this
standard. Impact the vehicle traveling longitudinally forward at any
speed, up to and including 48 km/h (30 mph), into a fixed rigid barrier
that is perpendicular within a tolerance of 5 degrees to
the line of travel of the vehicle under the applicable conditions of
S16.2 of this standard.
(b) Unbelted test. Place a 49 CFR Part 572 Subpart O 5th percentile
adult female test dummy at each front outboard seating position of a
vehicle, in accordance with the procedures specified in S16.3 of this
standard, except S16.3.5. Impact the vehicle traveling longitudinally
forward at any speed, from 32 km/h (20 mph) to 40 km/h (25 mph),
inclusive, into a fixed rigid barrier that is perpendicular within a
tolerance of 5 degrees to the line of travel of the vehicle
under the applicable conditions of S16.2 of this standard.
S16.2 Test conditions.
S16.2.1 The vehicle, including test devices and instrumentation, is
loaded as in S8.1.1.
S16.2.2 Movable vehicle windows and vents are placed in the fully
closed position, unless the vehicle manufacturer chooses to specify a
different adjustment position prior to the time the vehicle is
certified.
S16.2.3 Convertibles and open-body type vehicles have the top, if
any, in place in the closed passenger compartment configuration.
S16.2.4 Doors are fully closed and latched but not locked.
S16.2.5 The dummy is clothed in form fitting cotton stretch garments
with short sleeves and above the knee length pants. A size 7 1/2W shoe
which meets the configuration and size specifications of MIL-S-21711E
(see S4.7) or its equivalent is placed on each foot of the test dummy.
S16.2.6 Limb joints are set at one g, barely restraining the weight
of the limb when extended horizontally. Leg joints are adjusted with the
torso in the supine position.
S16.2.7 Instrumentation shall not affect the motion of dummies
during impact.
S16.2.8 The stabilized temperature of the dummy is at any level
between 20.6 deg.C and 22.2 deg.C ( 69 deg.F to 72 deg.F).
S16.2.9 Steering wheel adjustment.
S16.2.9.1 Adjust a tiltable steering wheel, if possible, so that the
steering wheel hub is at the geometric center of its full range of
driving positions.
S16.2.9.2 If there is no setting detent at the mid-position, lower
the steering wheel to the detent just below the mid-position.
S16.2.9.3 If the steering column is telescoping, place the steering
column in the mid-position. If there is no mid-position, move the
steering wheel rearward one position from the mid-position.
S16.2.10 Driver and passenger seat set-up.
S16.2.10.1 Lumbar support adjustment. Position adjustable lumbar
supports so that the lumbar support is in its lowest, retracted or
deflated adjustment position.
S16.2.10.2 Other seat adjustments. Position any adjustable parts of
the seat that provide additional support so that they are in the lowest
or most open adjustment position.
S16.2.10.3 Seat position adjustment. If the passenger seat does not
adjust independently of the driver seat, the
[[Page 520]]
driver seat shall control the final position of the passenger seat.
S16.2.10.3.1 If the seat is adjustable in the fore and aft and/or
vertical directions, move the seat to the rearmost position at the full
down height adjustment. If the seat cushion adjusts fore and aft,
independent of the seat back, set this adjustment to the full rearward
position. If the seat cushion contains a height adjustment, independent
of the seat back, set this adjustment to the full down position. Record
a seat cushion reference angle.
S16.2.10.3.2 Using only controls which move the seat fore and aft,
move the seat to the full forward position. If seat adjustments other
than fore-aft are present and the seat cushion reference angle changes
from that measured in S16.2.10.3.1, use those adjustments to maintain as
closely as possible the angle recorded in S16.2.10.3.1.
S16.2.10.3.3 If the seat height is adjustable, determine the maximum
and minimum heights at this position, while maintaining, as closely as
possible, the angle recorded in S16.2.10.3.1. Set the seat at the
midpoint height with the seat cushion reference angle set as closely as
possible to the angle recorded in S16.2.10.3.1. Mark location of the
seat for future reference.
S16.3 Dummy seating positioning procedures. The 49 CFR Part 572
Subpart O 5th percentile adult female test dummy is positioned as
follows:
S16.3.1 General provisions and definitions.
S16.3.1.1 All angles are measured with respect to the horizontal
plane unless otherwise stated.
S16.3.1.2 The dummy's neck bracket is adjusted to align the zero
degree index marks.
S16.3.1.3 The term ``midsagittal plane'' refers to the vertical
plane that separates the dummy into equal left and right halves.
S16.3.1.4 The term ``vertical longitudinal plane'' refers to a
vertical plane parallel to the vehicle's longitudinal centerline.
S16.3.1.5 The term ``vertical plane'' refers to a vertical plane,
not necessarily parallel to the vehicle's longitudinal centerline.
S16.3.1.6 The term ``transverse instrumentation platform'' refers to
the transverse instrumentation surface inside the dummy's skull casting
to which the neck load cell mounts. This surface is perpendicular to the
skull cap's machined inferior-superior mounting surface.
S16.3.1.7 The term ``thigh'' refers to the femur between, but not
including, the knee and the pelvis.
S16.3.1.8 The term ``leg'' refers to the lower part of the entire
leg including the knee.
S16.3.1.9 The term ``foot'' refers to the foot including the ankle.
S16.3.1.10 The longitudinal centerline of a bucket seat cushion is
determined at the widest part of the seat cushion. Measure perpendicular
to the longitudinal centerline of the vehicle.
S16.3.1.11 For leg and thigh angles use the following references:
S16.3.1.11.1 Thigh--a straight line on the thigh skin between the
center of the \1/2\-13 UNC-2B tapped hole in the upper leg femur clamp
(see drawings 880105-504 (left thigh) and 880105-505 (right thigh),
upper leg femur clamp) and the knee pivot shoulder bolt (part 880105-527
in drawing 880105-528R & 528L, sliding knee assy. w/o pot).
S16.3.1.11.2 Leg--a straight line on the leg skin between the center
of the ankle shell (parts 880105-609 & 633 in drawing 880105-660, ankle
assembly) and the knee pivot shoulder bolt (part 880105-527 in drawing
880105-528R & 528L, sliding knee assy. w/o pot).
S16.3.2 Driver dummy positioning.
S16.3.2.1 Driver torso/head/seat back angle positioning.
S16.3.2.1.1 With the seat in the position determined in S16.2.10,
use only the controls which move the seat fore and aft to place the seat
in the rearmost position, without adjusting independent height controls.
If the seat cushion reference angle automatically changes as the seat is
moved from the full forward position, maintain, as closely as possible,
the seat cushion reference angle in S16.2.10.3.1, for the final forward
position when measuring the pelvic angle as specified in S16.3.2.1.11.
S16.3.2.1.2 Fully recline the seat back, if adjustable. Install the
dummy into the driver's seat, such that when the legs are positioned 120
degrees to
[[Page 521]]
the thighs, the calves of the legs are not touching the seat cushion.
S16.3.2.1.3 Bucket seats. Center the dummy on the seat cushion so
that its midsagittal plane is vertical and coincides with the vertical
longitudinal plane through the center of the seat cushion.
S16.3.2.1.4 Bench seats. Position the midsagittal plane of the dummy
vertical and parallel to the vehicle's longitudinal centerline and
aligned with the center of the steering wheel rim.
S16.3.2.1.5 Hold the dummy's thighs down and push rearward on the
upper torso to maximize the dummy's pelvic angle.
S16.3.2.1.6 Place the legs at 120 degrees to the thighs. Set the
initial transverse distance between the longitudinal centerlines at the
front of the dummy's knees at 160 to 170 mm (6.3 to 6.7 in), with the
thighs and legs of the dummy in vertical planes. Push rearward on the
dummy's knees to force the pelvis into the seat so there is no gap
between the pelvis and the seat back or until contact occurs between the
back of the dummy's calves and the front of the seat cushion.
S16.3.2.1.7 Gently rock the upper torso relative to the lower torso
laterally in a side to side motion three times through a 5
degree arc (approximately 51 mm (2 in) side to side) to reduce friction
between the dummy and the seat.
S16.3.2.1.8 If needed, extend the legs slightly so that the feet are
not in contact with the floor pan. Let the thighs rest on the seat
cushion to the extent permitted by the foot movement. Keeping the leg
and the thigh in a vertical plane, place the foot in the vertical
longitudinal plane that passes through the centerline of the accelerator
pedal. Rotate the left thigh outboard about the hip until the center of
the knee is the same distance from the midsagittal plane of the dummy as
the right knee 5 mm (0.2 in). Using only
controls which move the seat fore and aft, attempt to return the seat to
the full forward position. If either of the dummy's legs first contacts
the steering wheel, then adjust the steering wheel, if adjustable,
upward until contact with the steering wheel is avoided. If the steering
wheel is not adjustable, separate the knees enough to avoid steering
wheel contact. Proceed with moving the seat forward until either the leg
contacts the vehicle interior or the seat reaches the full forward
position. (The right foot may contact and depress the accelerator and/or
change the angle of the foot with respect to the leg during seat
movement.) If necessary to avoid contact with the vehicles brake or
clutch pedal, rotate the test dummy's left foot about the leg. If there
is still interference, rotate the left thigh outboard about the hip the
minimum distance necessary to avoid pedal interference. If a dummy leg
contacts the vehicle interior before the full forward position is
attained, position the seat at the next detent where there is no
contact. If the seat is a power seat, move the seat fore and aft to
avoid contact while assuring that there is a maximum of 5 mm (0.2 in)
distance between the vehicle interior and the point on the dummy that
would first contact the vehicle interior. If the steering wheel was
moved, return it to the position described in S16.2.9. If the steering
wheel contacts the dummy's leg(s) prior to attaining this position,
adjust it to the next higher detent, or if infinitely adjustable, until
there is 5 mm (0.2 in) clearance between the wheel and the dummy's
leg(s).
S16.3.2.1.9 For vehicles without adjustable seat backs, adjust the
lower neck bracket to level the head as much as possible. For vehicles
with adjustable seat backs, while holding the thighs in place, rotate
the seat back forward until the transverse instrumentation platform of
the head is level to within 0.5 degree, making sure that the
pelvis does not interfere with the seat bight. Inspect the abdomen to
ensure that it is properly installed. If the torso contacts the steering
wheel, adjust the steering wheel in the following order until there is
no contact: telescoping adjustment, lowering adjustment, raising
adjustment. If the vehicle has no adjustments or contact with the
steering wheel cannot be eliminated by adjustment, position the seat at
the next detent where there is no contact with the steering wheel as
adjusted in S16.2.9. If the seat is a power seat, position the seat to
avoid contact
[[Page 522]]
while assuring that there is a maximum of 5 mm (0.2 in) distance between
the steering wheel as adjusted in S16.2.9 and the point of contact on
the dummy.
S16.3.2.1.10 If it is not possible to achieve the head level within
0.5 degrees, minimize the angle.
S16.3.2.1.11 Measure and set the dummy's pelvic angle using the
pelvic angle gage (drawing TE-2504, incorporated by reference in 49 CFR
Part 572, Subpart O, of this chapter). The angle shall be set to 20.0
degrees 2.5 degrees. If this is not possible, adjust the
pelvic angle as close to 20.0 degrees as possible while keeping the
transverse instrumentation platform of the head as level as possible by
adjustments specified in S16.3.2.1.9 and S16.3.2.1.10.
S16.3.2.1.12 If the dummy is contacting the vehicle interior after
these adjustments, move the seat rearward until there is a maximum of 5
mm (0.2 in) between the contact point of the dummy and the interior of
the vehicle or if it has a manual seat adjustment, to the next rearward
detent position. If after these adjustments, the dummy contact point is
more than 5 mm (0.2 in) from the vehicle interior and the seat is still
not in its forwardmost position, move the seat forward until the contact
point is 5 mm (0.2 in) or less from the vehicle interior, or if it has a
manual seat adjustment, move the seat to the closest detent position
without making contact, or until the seat reaches its forwardmost
position, whichever occurs first.
S16.3.2.2 Driver foot positioning.
S16.3.2.2.1 If the vehicle has an adjustable accelerator pedal,
adjust it to the full forward position. Rest the right foot of the test
dummy on the undepressed accelerator pedal with the rearmost point of
the heel on the floor pan in the plane of the pedal. If the foot cannot
be placed on the accelerator pedal, set it initially perpendicular to
the leg and then place it as far forward as possible in the direction of
the pedal centerline with the rearmost point of the heel resting on the
floor pan. If the vehicle has an adjustable accelerator pedal and the
right foot is not touching the accelerator pedal when positioned as
above, move the pedal rearward until it touches the right foot. If the
accelerator pedal in the full rearward position still does not touch the
foot, leave the pedal in that position.
S16.3.2.2.2 If the ball of the foot does not contact the pedal,
change the angle of the foot relative to the leg such that the toe of
the foot contacts the undepressed accelerator pedal.
S16.3.2.2.3 Place the left foot on the toe-board with the rearmost
point of the heel resting on the floor pan as close as possible to the
point of intersection of the planes described by the toe-board and floor
pan, and not on the wheel-well projection or foot rest.
S16.3.2.2.4 If the left foot cannot be positioned on the toe board,
place the foot perpendicular to the lower leg centerline as far forward
as possible with the heel resting on the floor pan.
S16.3.2.2.5 If necessary to avoid contact with the vehicle's brake
or clutch pedal, rotate the test dummy's left foot about the lower leg.
If there is still pedal interference, rotate the left leg outboard about
the hip the minimum distance necessary to avoid the pedal interference.
If the left foot does not contact the floor pan, place the foot parallel
to the floor and place the leg as perpendicular to the thigh as
possible.
S16.3.2.3 Driver arm/hand positioning.
S16.3.2.3.1 Place the dummy's upper arms adjacent to the torso with
the arm centerlines as close to a vertical longitudinal plane as
possible.
S16.3.2.3.2 Place the palms of the dummy in contact with the outer
part of the steering wheel rim at its horizontal centerline with the
thumbs over the steering wheel rim.
S16.3.2.3.3 If it is not possible to position the thumbs inside the
steering wheel rim at its horizontal centerline, then position them
above and as close to the horizontal centerline of the steering wheel
rim as possible.
S16.3.2.3.4 Lightly tape the hands to the steering wheel rim so that
if the hand of the test dummy is pushed upward by a force of not less
than 9 N (2 lb) and not more than 22 N (5 lb), the tape releases the
hand from the steering wheel rim.
S16.3.3 Passenger dummy positioning.
[[Page 523]]
S16.3.3.1 Passenger torso/head/seat back angle positioning.
S16.3.3.1.1 With the seat in the position determined in S16.2.10,
use only the controls which move the seat fore and aft to place the seat
in the rearmost position, without adjusting independent height controls.
If the seat cushion reference angle automatically changes as the seat is
moved from the full forward position, maintain as closely as possible
the seat cushion reference angle in S16.2.10.3.1, for the final forward
position when measuring the pelvic angle as specified in S16.3.3.1.11.
S16.3.3.1.2 Fully recline the seat back, if adjustable. Install the
dummy into the passenger's seat, such that when the legs are 120 degrees
to the thighs, the calves of the legs are not touching the seat cushion.
S16.3.3.1.3 Bucket seats. Center the dummy on the seat cushion so
that its midsagittal plane is vertical and coincides with the vertical
longitudinal plane through the center of the seat cushion.
S16.3.3.1.4 Bench seats. Position the midsagittal plane of the dummy
vertical and parallel to the vehicle's longitudinal centerline and the
same distance from the vehicle's longitudinal centerline as the
midsagittal plane of the driver dummy.
S16.3.3.1.5 Hold the dummy's thighs down and push rearward on the
upper torso to maximize the dummy's pelvic angle.
S16.3.3.1.6 Place the legs at 120 degrees to the thighs. Set the
initial transverse distance between the longitudinal centerlines at the
front of the dummy's knees at 160 to 170 mm (6.3 to 6.7 in), with the
thighs and legs of the dummy in vertical planes. Push rearward on the
dummy's knees to force the pelvis into the seat so there is no gap
between the pelvis and the seat back or until contact occurs between the
back of the dummy's calves and the front of the seat cushion.
S16.3.3.1.7 Gently rock the upper torso relative to the lower torso
laterally side to side three times through a 5 degree arc
(approximately 51 mm (2 in) side to side).
S16.3.3.1.8 If needed, extend the legs slightly so that the feet are
not in contact with the floor pan. Let the thighs rest on the seat
cushion to the extent permitted by the foot movement. With the feet
perpendicular to the legs, place the heels on the floor pan. If a heel
will not contact the floor pan, place it as close to the floor pan as
possible. Using only controls which move the seat fore and aft, attempt
to return the seat to the full forward position. If a dummy leg contacts
the vehicle interior before the full forward position is attained,
position the seat at the next detent where there is no contact. If the
seats are power seats, position the seat to avoid contact while assuring
that there is a maximum of 5 mm (0.2 in) distance between the vehicle
interior and the point on the dummy that would first contact the vehicle
interior.
S16.3.3.1.9 For vehicles without adjustable seat backs, adjust the
lower neck bracket to level the head as much as possible. For vehicles
with adjustable seat backs, while holding the thighs in place, rotate
the seat back forward until the transverse instrumentation platform of
the head is level to within 0.5 degrees, making sure that
the pelvis does not interfere with the seat bight. Inspect the abdomen
to insure that it is properly installed.
S16.3.3.1.10 If it is not possible to orient the head level within
0.5 degrees, minimize the angle.
S16.3.3.1.11 Measure and set the dummy's pelvic angle using the
pelvic angle gage (drawing TE-2504, incorporated by reference in 49 CFR
Part 572, Subpart O, of this chapter). The angle shall be set to 20.0
degrees 2.5 degrees. If this is not possible, adjust the
pelvic angle as close to 20.0 degrees as possible while keeping the
transverse instrumentation platform of the head as level as possible as
specified in S16.3.3.1.9 and S16.3.3.1.10.
S16.3.3.1.12 If the dummy is contacting the vehicle interior after
these adjustments, move the seat rearward until there is a maximum of 5
mm (0.2 in) between the contact point of the dummy and the interior of
the vehicle or if it has a manual seat adjustment, to the next rearward
detent position. If after these adjustments the dummy contact point is
more than 5 mm (0.2 in) from the vehicle interior and the
[[Page 524]]
seat is still not in its forward most position, move the seat forward
until the contact point is 5 mm (0.2 in) or less from the vehicle
interior, or if it has a manual seat adjustment, move the seat to the
closest detent position without making contact, or until the seat
reaches its forward most position, whichever occurs first.
S16.3.3.2 Passenger foot positioning.
S16.3.3.2.1 Place the passenger's feet flat on the toe board.
S16.3.3.2.2 If the feet cannot be placed flat on the toe board, set
them perpendicular to the leg center lines and place them as far forward
as possible with the heels resting on the floor pan.
S16.3.3.3 Passenger arm/hand positioning.
S16.3.3.3.1 Place the dummy's upper arms in contact with the seat
back and the torso.
S16.3.3.3.2 Place the palms of the dummy in contact with the outside
of the thighs.
S16.3.3.3.3 Place the little fingers in contact with the seat
cushion.
S16.3.4 Driver and passenger adjustable head restraints.
S16.3.4.1 If the head restraint has an automatic adjustment, leave
it where the system positions the restraint after the dummy is placed in
the seat.
S16.3.4.2 Adjust each head restraint to its lowest position.
S16.3.4.3 Measure the vertical distance from the top most point of
the head restraint to the bottom most point. Locate a horizontal plane
through the midpoint of this distance. Adjust each head restraint
vertically so that this horizontal plane is aligned with the center of
gravity (CG) of the dummy head.
S16.3.4.3 If the above position is not attainable, move the vertical
center of the head restraint to the closest detent below the center of
the head CG.
S16.3.4.4 If the head restraint has a fore and aft adjustment, place
the restraint in the forwardmost position or until contact with the head
is made, whichever occurs first.
S16.3.5 Driver and passenger manual belt adjustment (for tests
conducted with a belted dummy)
S16.3.5.1 If an adjustable seat belt D-ring anchorage exists, place
it in the manufacturer's design position for a 5th percentile adult
female with the seat in the position specified in S16.2.10.3.
S16.3.5.2 Place the Type 2 manual belt around the test dummy and
fasten the latch.
S16.3.5.3 Ensure that the dummy's head remains as level as possible,
as specified in S16.3.2.1.9 and S16.3.2.1.10 and S16.3.3.1.9 and
S16.3.3.1.10.
S16.3.5.4 Remove all slack from the lap belt. Pull the upper torso
webbing out of the retractor and allow it to retract; repeat this
operation four times. Apply a 9 N (2 lbf) to 18 N (4 lbf) tension load
to the lap belt. If the belt system is equipped with a tension-relieving
device, introduce the maximum amount of slack into the upper torso belt
that is recommended by the manufacturer. If the belt system is not
equipped with a tension-relieving device, allow the excess webbing in
the shoulder belt to be retracted by the retractive force of the
retractor.
S17 Offset frontal deformable barrier requirements using 5th
percentile adult female test dummies. Each vehicle that is certified as
complying with S14 shall, at each front outboard designated seating
position, meet the injury criteria specified in S15.3 of this standard
when the vehicle is crash tested in accordance with the procedures

adult female dummy).
S19.2.2 The vehicle shall be equipped with at least one telltale
which emits light whenever the passenger air bag system is deactivated
and does not emit light whenever the passenger air bag system is
activated, except that the telltale(s) need not illuminate when the
passenger seat is unoccupied. Each telltale:
(a) Shall emit yellow light;
(b) Shall have the identifying words ``PASSENGER AIR BAG OFF'' or
``PASS AIR BAG OFF'' on the telltale or within 25 mm (1.0 in) of the
telltale; and
(c) Shall not be combined with the readiness indicator required by
S4.5.2 of this standard.
(d) Shall be located within the interior of the vehicle and forward
of and above the design H-point of both the driver's and the right front
passenger's seat in their forwardmost seating positions and shall not be
located on or adjacent to a surface that can be used for temporary or
permanent storage where use of the storage space could obscure the
telltale from either the driver's or right front passenger's view, or
where the telltale would be obscured from the driver's view if a rear
facing child restraint is installed in the right front passenger's seat.
(e) Shall be visible and recognizable to a driver and right front
passenger during night and day when the occupants have adapted to the
ambient light roadway conditions.
(f) Telltales need not be visible or recognizable when not
activated.
(g) Means shall be provided for making telltales and their
identification visible and recognizable to the driver and right front
passenger under all driving conditions. The means for providing the
required visibility may be adjustable manually or automatically, except
that the telltales and their identifications may not be adjustable under
any driving conditions to a level that they become invisible or not
recognizable to the driver and right front passenger.
(h) The telltale must not emit light except when the passenger air
bag is urned off or during a bulb check upon vehicle starting.
[[Page 526]]
S19.2.3 The vehicle shall be equipped with a mechanism that
indicates whether the air bag system is suppressed, regardless of
whether the passenger seat is occupied. The mechanism need not be
located in the occupant compartment unless it is the telltale described
in S19.2.2.
S19.3 Option 2--Low risk deployment. Each vehicle shall meet the
injury criteria specified in S19.4 of this standard when the passenger
air bag is deployed in accordance with the procedures specified in

S19.4 Injury criteria for the 49 CFR Part 572, Subpart R 12-month-
old CRABI test dummy.
S19.4.1 All portions of the test dummy and child restraint shall be
contained within the outer surfaces of the vehicle passenger
compartment.
S19.4.2 Head injury criteria.
(a) For any two points in time, t1 and t2,
during the event which are separated by not more than a 15 millisecond
time interval and where t1 is less than t2, the
head injury criterion (HIC15) shall be determined using the
resultant head acceleration at the center of gravity of the dummy head,
ar, expressed as a multiple of g (the acceleration of
gravity) and shall be calculated using the expression:
[GRAPHIC] [TIFF OMITTED] TR18DE01.000
(b) The maximum calculated HIC15 value shall not exceed
390.
S19.4.3 The resultant acceleration calculated from the output of the
thoracic instrumentation shall not exceed 50 g's, except for intervals
whose cumulative duration is not more than 3 milliseconds.
S19.4.4 Neck injury. When measuring neck injury, each of the
following injury criteria shall be met.
(a) Nij.
(1) The shear force (Fx), axial force (Fz), and bending moment (My)
shall be measured by the dummy upper neck load cell for the duration of
the crash event as specified in S4.11. Shear force, axial force, and
bending moment shall be filtered for Nij purposes at SAE J211/1 rev.
Mar95 Channel Frequency Class 600 (see S4.7).
(2) During the event, the axial force (Fz) can be either in tension
or compression while the occipital condyle bending moment (Mocy) can be
in either flexion or extension. This results in four possible loading
conditions for Nij: tension-extension (Nte), tension-flexion (Ntf),
compression-extension (Nce), or compression-flexion (Ncf).
(3) When calculating Nij using equation S19.4.4(a)(4), the critical
values, Fzc and Myc, are:
(i) Fzc = 1460 N (328 lbf) when Fz is in tension
(ii) Fzc = 1460 N (328 lbf) when Fz is in compression
(iii) Myc = 43 Nm (32 lbf-ft) when a flexion moment exists at the
occipital condyle
(iv) Myc = 17 Nm (13 lbf-ft) when an extension moment exists at the
occipital condyle.
(4) At each point in time, only one of the four loading conditions
occurs and the Nij value corresponding to that loading condition is
computed and the three remaining loading modes shall be considered a
value of zero. The expression for calculating each Nij loading condition
is given by:
Nij ' (Fz / Fzc) + (Mocy / Myc)
(5) None of the four Nij values shall exceed 1.0 at any time during
the event.
(b) Peak tension. Tension force (Fz), measured at the upper neck
load cell, shall not exceed 780 N (175 lbf) at any time.
(c) Peak compression. Compression force (Fz), measured at the upper
neck load cell, shall not exceed 960 N (216 lbf) at any time.
S19.4.5 Unless otherwise indicated, instrumentation for data
acquisition, data channel frequency class, and moment calculations are
the same as given for the 49 CFR Part 572 Subpart R 12-month-old CRABI
test dummy.

S21.5 Injury criteria for the 49 CFR Part 572, Subpart P 3-year-old
child test dummy.
S21.5.1 All portions of the test dummy shall be contained within the
outer surfaces of the vehicle passenger compartment.
S21.5.2 Head injury criteria.
(a) For any two points in time, t1 and t2,
during the event which are separated by not more than a 15 millisecond
time interval and where t1 is less than t2, the
head injury criterion (HIC15) shall be determined using the
resultant head acceleration at the center of gravity of the dummy head,
ar, expressed as a multiple of g (the acceleration of
gravity) and shall be calculated using the expression:
[GRAPHIC] [TIFF OMITTED] TR18DE01.001
(b) The maximum calculated HIC15 value shall not exceed
570.
S21.5.3 The resultant acceleration calculated from the output of the
thoracic instrumentation shall not exceed 55 g's, except for intervals
whose cumulative duration is not more than 3 milliseconds.
S21.5.4 Compression deflection of the sternum relative to the spine,
as determined by instrumentation, shall not exceed 34 millimeters (1.3
in).
S21.5.5 Neck injury. When measuring neck injury, each of the
following injury criteria shall be met.
(a) Nij.
(1) The shear force (Fx), axial force (Fz), and bending moment (My)
shall be measured by the dummy upper neck load cell for the duration of
the crash event as specified in S4.11. Shear force, axial force, and
bending moment shall be filtered for Nij purposes at SAE J211/1 rev.
Mar95 Channel Frequency Class 600 (see S4.7).
(2) During the event, the axial force (Fz) can be either in tension
or compression while the occipital condyle bending moment (Mocy) can be
in either flexion or extension. This results in four possible loading
conditions for Nij: Tension-extension (Nte), tension-flexion (Ntf),
compression-extension (Nce), or compression-flexion (Ncf).
(3) When calculating Nij using equation S21.5.5(a)(4), the critical
values, Fzc and Myc, are:
(i) Fzc = 2120 N (477 lbf) when Fz is in tension
(ii) Fzc = 2120 N (477 lbf) when Fz is in compression
(iii) Myc = 68 Nm (50 lbf-ft) when a flexion moment exists at the
occipital condyle
(iv) Myc = 27 Nm (20 lbf-ft) when an extension moment exists at the
occipital condyle.
(4) At each point in time, only one of the four loading conditions
occurs and the Nij value corresponding to that loading condition is
computed and the three remaining loading modes shall be considered a
value of zero. The expression for calculating each Nij loading condition
is given by:
Nij = (Fz / Fzc) + (Mocy / Myc)
(5) None of the four Nij values shall exceed 1.0 at any time during
the event.
[[Page 532]]
(b) Peak tension. Tension force (Fz), measured at the upper neck
load cell, shall not exceed 1130 N (254 lbf) at any time.
(c) Peak compression. Compression force (Fz), measured at the upper
neck load cell, shall not exceed 1380 N (310 lbf) at any time.
S21.5.6 Unless otherwise indicated, instrumentation for data
acquisition, data channel frequency class, and moment calculations are
the same as given in 49 CFR Part 572 Subpart P 3-year-old child test
dummy.

conducted with the right front outboard seating position at the full
rearward, middle, and, subject to S16.3.3.1.8, full forward positions.
All tests are conducted with the seat height, if adjustable, in the mid-
height position.
S22.3.2 Place a 49 CFR Part 572 Subpart O 5th percentile adult
female test dummy at the right front outboard seating position of the
vehicle, in accordance with procedures specified in S16.3.3 of this
standard, except as specified in S22.3.1. Do not fasten the seat belt.
S22.3.3 Start the vehicle engine or place the ignition in the ``on''
position, whichever will turn on the suppression system, and then close
all vehicle doors.
S22.3.4 Wait 10 seconds, then check whether the air bag system is
activated.
S22.4 Low risk deployment tests.
S22.4.1 Each vehicle that is certified as complying with S21.4 shall
meet the following test requirements with the 49 CFR Part 572, Subpart P
3-year-old child dummy in both of the following positions: Position 1
(S22.4.2) and Position 2 (S22.4.3).
S22.4.1.1 Locate and mark a point on the front of the dummy's chest
jacket on the midsaggital plane which is 114 mm (4.5 in) 3
mm ( 0.1 in) along the surface of the skin from the top of
the skin at the neck line. This is referred to as ``Point 1.''
S22.4.1.2 Locate the vertical plane parallel to the vehicle
longitudinal centerline through the geometric center of the opening
through which the right front air bag deploys into the occupant
compartment. This is referred to as ``Plane D.''
S22.4.1.3 Locate the horizontal plane through the geometric center
of the opening through which the right front
[[Page 537]]
air bag deploys into the occupant compartment. This is referred to as
``Plane C.''
S22.4.2 Position 1 (chest on instrument panel).
S22.4.2.1 If a seat is adjustable in the fore and aft and/or
vertical directions, move the seat to the rear-most seating position and
full-down height adjustment. If the seat cushion adjusts fore and aft,
independent of the entire seat, adjust the seat cushion to the full-
rearward position. If the seat back is adjustable, place the seat back
at the manufacturer's nominal design seat back angle for a 50th
percentile adult male as specified in S8.1.3. Position any adjustable
parts of the seat that provide additional support so that they are in
the lowest or most open adjustment position. If adjustable, set the head
restraint in the lowest position.
S22.4.2.2 Place the dummy in the front passenger seat such that:
S22.4.2.2.1 The midsagittal plane is coincident with Plane D.
S22.4.2.2.2 The legs are initially vertical to the floor pan. The
legs and thighs shall be adjusted to the extent necessary for the head/
torso to contact the instrument panel as specified in S22.4.2.3.
S22.4.2.2.3 The upper arms are parallel to the torso and the hands
are in contact with the thighs.
S22.4.2.3 Without changing the seat position and with the dummy's
thorax instrument cavity rear face vertical, move the dummy forward
until the dummy head/torso contacts the instrument panel. If the dummy
loses contact with the seat cushion because of the forward movement,
maintain the height of the dummy and the angle of the thigh with respect
to the torso. Once contact is made, raise the dummy vertically until
Point 1 lies in Plane C. If the dummy's head contacts the windshield and
keeps Point 1 from reaching Plane C, lower the dummy until there is no
more than 5 mm (0.2 in) clearance between the head and the windshield.
(The dummy shall remain in contact with the instrument panel while being
raised or lowered, which may change the dummy's fore-aft position.)
S22.4.2 If possible, position the legs of the dummy so that the legs
are vertical and the feet rest flat on the floor pan of the vehicle. If
the positioning against the instrument panel does not allow the feet to
be on the floor pan, the feet shall be parallel to the floor pan.
S22.4.2.5 If necessary, material with a maximum breaking strength of
311 N (70 lb) and spacer blocks may be used to support the dummy in
position. The material should support the torso rather than the head.
Support the dummy so that there is minimum interference with the full
rotational and translational freedom for the upper torso of the dummy
and the material does not interfere with the air bag.
S22.4.3 Position 2 (head on instrument panel).
S22.4.3.1 Place the passenger seat in the full rearward seating
position. Place the seat back at the manufacturer's nominal design seat
back angle for a 50th percentile adult male as specified in S8.1.3. If
adjustable in the vertical direction, place the seat in the mid-height
position. If the seat cushion adjusts fore and aft, independent of the
entire seat, adjust the seat cushion to the full rearward position.
Position any adjustable parts of the seat that provide additional
support so that they are in the lowest or most open adjustment position.
If adjustable, set the head restraint in the lowest position.
S22.4.3.2 Place the dummy in the front passenger seat such that:
S22.4.3.2.1 The midsagittal plane is coincident with Plane D.
S22.4.3.2.2 The legs are vertical to the floor pan, the back of the
legs are in contact with the seat cushion, and the dummy's thorax
instrument cavity rear face is vertical. If it is not possible to
position the dummy with the legs in the prescribed position, rotate the
legs forward until the dummy is resting on the seat with the feet
positioned flat on the floor pan, and the back of the legs are in
contact with the front of the seat cushion. Set the transverse distance
between the longitudinal centerlines at the front of the dummy's knees
at 86 to 91 mm (3.4 to 3.6 in), with the thighs and the legs of the
dummy in vertical planes.
S22.4.3.2.3 The upper arms are parallel to the torso and the hands
are in contact with the thighs.
[[Page 538]]
S22.4.3.3 Move the seat forward, while maintaining the thorax
instrument cavity rear face orientation until any part of the dummy
contacts the vehicle's instrument panel.
S22.4.3.4 If dummy contact has not been made with the vehicle's
instrument panel at the full forward seating position of the seat, slide
the dummy forward until contact is made. Maintain the thorax instrument
cavity rear face vertical orientation, the height of the dummy, and the
angle of the thigh with respect to the horizontal.
S22.4.3.5 If head/torso contact with the instrument panel has not
been made, maintain the angle of the thighs with respect to the
horizontal while applying a force towards the front of the vehicle on
the spine of the dummy between the shoulder joints until the head or
torso comes into contact with the vehicle's instrument panel.
S22.4.3.6 If necessary, material with a maximum breaking strength of
311 N (70 lb) and spacer blocks may be used to support the dummy in
position. The material should support the torso rather than the head.
Support the dummy so that there is minimum interference with the full
rotational and translational freedom for the upper torso of the dummy
and the material does not interfere with the air bag.
S22.4.4 Deploy the right front outboard frontal air bag system. If
the frontal air bag system contains a multistage inflator, the vehicle
shall be able to comply with the injury criteria at any stage or
combination of stages or time delay between successive stages that could
occur in a rigid barrier crash test at or below 26 km/h (16 mph), under
the test procedure specified in S22.5.
S22.5 Test procedure for determining stages of air bag systems
subject to low risk deployment (low speed crashes) test requirement.
S22.5.1 The test described in S22.5.2 shall be conducted with an
unbelted 50th percentile adult male test dummy in the driver seating
position according to S8 as it applies to that seating position and an
unbelted 5th percentile adult female test dummy either in the right
front seating position according to S16 as it applies to that seating
position or at any fore-aft seat position on the passenger side.
S22.5.2 Impact the vehicle traveling longitudinally forward at any
speed, up to and including 26 km/h (16 mph) into a fixed rigid barrier
that is perpendicular 5 degrees to the line of travel of
the vehicle under the applicable conditions of S8, S10, and S16
excluding S10.7, S10.8, S10.9, and S16.3.5.
S22.5.3 Determine which inflation stage or combination of stages are
fired and determine the time delay between successive stages. That stage
or combination of stages, with time delay between successive stages,
shall be used in deploying the air bag when conducting the low risk
deployment tests described in S22.4, S24.4, and S26.
S22.5.4 If the air bag does not deploy in the impact described in
S22.5.2, the low risk deployment tests described in S22.4, S24.4, and
S26 shall be conducted with all stages using the maximum time delay
between stages.
S23 Requirements using 6-year-old child dummies.
S23.1 Each vehicle that is certified as complying with S14 shall, at
the option of the manufacturer, meet the requirements specified in
S23.2, S23.3, or S23.4, under the test procedures specified in S24 or
S28, as applicable.
S23.2 Option 1--Automatic suppression feature. Each vehicle shall
meet the requirements specified in S23.2.1 through S23.2.3.
S23.2.1 The vehicle shall be equipped with an automatic suppression
feature for the passenger frontal air bag system which results in
deactivation of the air bag during each of the static tests specified in
S24.2 (using a 49 CFR Part 572 Subpart N 6-year-old child dummy in any
of the child restraints specified in section D of Appendix A of this
standard), and activation of the air bag system during each of the
static tests specified in S24.3 (using a 49 CFR Part 572 Subpart O 5th
percentile adult female dummy).
S23.2.2 The vehicle shall be equipped with a telltale light meeting
the requirements specified in S19.2.2.
S23.2.3 The vehicle shall be equipped with a mechanism that
indicates whether the air bag is suppressed, regardless of whether the
passenger seat is occupied. The mechanism need not
[[Page 539]]
be located in the occupant compartment unless it is the telltale
described in S23.2.2.
S23.3 Option 2--Dynamic automatic suppression system that suppresses
the air bag when an occupant is out of position. (This option is
available under the conditions set forth in S27.1.) The vehicle shall be
equipped with a dynamic automatic suppression system for the passenger
frontal air bag system which meets the requirements specified in S27.
S23.4 Option 3--Low risk deployment. Each vehicle shall meet the
injury criteria specified in S23.5 of this standard when the passenger
air bag is statically deployed in accordance with both of the low risk
deployment test procedures specified in S24.4.
S23.5 Injury criteria for the 49 CFR Part 572 Subpart N 6-year-old
child dummy.
S23.5.1 All portions of the test dummy shall be contained within the
outer surfaces of the vehicle passenger compartment.
S23.5.2 Head injury criteria.
(a) For any two points in time, t1 and t2,
during the event which are separated by not more than a 15 millisecond
time interval and where t1 is less than t2, the
head injury criterion (HIC15) shall be determined using the
resultant head acceleration at the center of gravity of the dummy head,
ar, expressed as a multiple of g (the acceleration of
gravity) and shall be calculated using the expression:
[GRAPHIC] [TIFF OMITTED] TR18DE01.001
(b) The maximum calculated HIC15 value shall not exceed
700.
S23.5.3 The resultant acceleration calculated from the output of the
thoracic instrumentation shall not exceed 60 g's, except for intervals
whose cumulative duration is not more than 3 milliseconds.
S23.5.4 Compression deflection of the sternum relative to the spine,
as determined by instrumentation, shall not exceed 40 mm (l.6 in).
S23.5.5 Neck injury. When measuring neck injury, each of the
following injury criteria shall be met.
(a) Nij.
(1) The shear force (Fx), axial force (Fz), and bending moment (My)
shall be measured by the dummy upper neck load cell for the duration of
the crash event as specified in S4.11. Shear force, axial force, and
bending moment shall be filtered for Nij purposes at SAE J211/1 rev.
Mar95 Channel Frequency Class 600 (see S4.7).
(2) During the event, the axial force (Fz) can be either in tension
or compression while the occipital condyle bending moment (Mocy) can be
in either flexion or extension. This results in four possible loading
conditions for Nij: tension-extension (Nte), tension-flexion (Ntf),
compression-extension (Nce), or compression-flexion (Ncf).
(3) When calculating Nij using equation S23.5.5(a)(4), the critical
values, Fzc and Myc, are:
(i) Fzc = 2800 N (629 lbf) when Fz is in tension
(ii) Fzc = 2800 N (629 lbf) when Fz is in compression
(iii) Myc = 93 Nm (69 lbf-ft) when a flexion moment exists at the
occipital condyle
(iv) Myc = 37 Nm (27 lbf-ft) when an extension moment exists at the
occipital condyle.
(4) At each point in time, only one of the four loading conditions
occurs and the Nij value corresponding to that loading condition is
computed and the three remaining loading modes shall be considered a
value of zero. The expression for calculating each Nij loading condition
is given by:
Nij = (Fz / Fzc) + (Mocy / Myc)
(5) None of the four Nij values shall exceed 1.0 at any time during
the event.
(b) Peak tension. Tension force (Fz), measured at the upper neck
load cell, shall not exceed 1490 N (335 lbf) at any time.
(c) Peak compression. Compression force (Fz), measured at the upper
neck load cell, shall not exceed 1820 N (409 lbf) at any time.
S23.5.6 Unless otherwise indicated, instrumentation for data
acquisition, data channel frequency class, and moment calculations are
the same as given for the 49 CFR Part 572 Subpart N 6-year-old child
test dummy.

S24 Test procedure for S23.
S24.1 General provisions and definitions.
S24.1.1 Tests specifying the use of a booster seat may be conducted
using any such restraint listed in section D of Appendix A of this
standard. The booster seat may be unused or have been previously used
only for automatic suppression. If it has been used, there shall not be
any visible damage prior to the test. Booster seats are to be used in
the manner appropriate for a 6-year-old child of the same height and
weight as the 6-year-old child dummy.
S24.1.2 Unless otherwise specified, each vehicle certified to this
option shall comply in tests conducted with the right front outboard
seating position at the full rearward seat track position, the middle
seat track position, and the full forward seat track position. If the
dummy contacts the vehicle interior, move the seat rearward to the next
detent that provides clearance. If the seat is a power seat, move the
seat rearward while assuring that there is a maximum of 5 mm (0.2 in)
distance between the vehicle interior and the point on the dummy that
would first contact the vehicle interior. All tests are conducted with
the seat height, if adjustable, in the mid-height position, and with the
seat back angle, if adjustable, at the manufacturer=s nominal design
seat back angle for a 50th percentile adult male as specified in S8.1.3.
S24.1.3 Except as otherwise specified, if the booster seat has an
anchorage system as specified in S5.9 of FMVSS No. 213 and is tested in
a vehicle with a right front outboard vehicle seat that has an anchorage
system as specified in FMVSS No. 225, the vehicle shall comply with the
belted test conditions with the restraint anchorage system attached to
the vehicle seat anchorage system and the vehicle seat belt unattached.
It shall also comply with the belted test conditions with the restraint
anchorage system unattached to the vehicle seat anchorage system and the
vehicle seat belt attached. The vehicle shall comply with the unbelted
test conditions with the restraint anchorage system unattached to the
vehicle seat anchorage system.
S24.1.4 Do not attach any tethers.
S24.1.5 The definitions provided in S16.3.1 through S16.3.10 apply
to the tests specified in S24.
S24.1.6 For leg and thigh angles, use the following references:

female test dummy at the right front outboard seating position of the
vehicle, in accordance with procedures specified in S16.3.3 of this
standard, except as specified in S24.3.1. Do not fasten the seat belt.
S24.3.3 Start the vehicle engine or place the ignition in the ``on''
position, whichever will turn on the suppression system, and then close
all vehicle doors.
S24.3.4 Wait 10 seconds, then check whether the air bag system is
activated.
S24.4 Low risk deployment tests.
S24.4.1 Each vehicle that is certified as complying with S23.4 shall
meet the following test requirements with the 49 CFR Part 572 Subpart N
6-year-old child dummy in both of the following positions: Position 1
(S24.4.2) or Position 2 (S24.4.3).
S24.4.1.1 Locate and mark a point on the front of the dummy's chest
jacket on the midsagittal plane which is 139 mm (5.5 in) 3
mm ( 0.1 in) along the surface of the skin from the top of
the skin at the neckline. This is referred to as ``Point 1.''
S24.4.1.2 Locate the vertical plane parallel to the vehicle
longitudinal centerline through the geometric center of the opening
through which the right front air bag deploys into the occupant
compartment. This is referred to as ``Plane D.''
S24.4.1.3 Locate the horizontal plane through the geometric center
of the opening through which the right front air bag deploys into the
occupant compartment. This is referred to as ``Plane C.''
S24.4.2 Position 1 (chest on instrument panel).
S24.4.2.1 If a seat is adjustable in the fore and aft and/or
vertical directions, move the seat to the rearmost seating position and
full down height adjustment. If the seat cushion adjusts fore and aft,
independent of the entire seat, adjust the seat cushion to the full
rearward position. If the seat back is adjustable, place the seat back
at the manufacturer's nominal design seat back angle for a 50th
percentile adult male as specified in S8.1.3. Position any adjustable
parts of the seat that provide additional support so that they are in
the lowest or most open adjustment position. Position an adjustable head
restraint in the lowest position.
S24.4.2.2 Remove the legs of the dummy at the pelvic interface.
S24.4.2.3 Place the dummy in the front passenger seat such that:
(a) The midsagittal plane is coincident with Plane D.
(b) The upper arms are parallel to the torso and the hands are next
to where the thighs would be.
(c) Without changing the seat position and with the dummy's thorax
instrument cavity rear face 6 degrees forward of the vertical, move the
dummy forward until the dummy head/torso contacts the instrument panel.
If the dummy loses contact with the seat cushion because of the forward
movement, maintain the height of the dummy while moving the dummy
forward. If the head contacts the windshield before head/torso contact
with the instrument panel, maintain the
[[Page 542]]
thorax instrument cavity angle and move the dummy forward such that the
head is following the angle of the windshield until there is head/torso
contact with the instrument panel. Once contact is made, raise or lower
the dummy vertically until Point 1 lies in Plane C. If the dummy's head
contacts the windshield and keeps Point 1 from reaching Plane C, lower
the dummy until there is no more than 5 mm (0.2 in) clearance between
the head and the windshield. (The dummy shall remain in contact with the
instrument panel while being raised or lowered which may change the
dummy's fore-aft position.)
S24.4.2.4 If necessary, material with a maximum breaking strength of
311 N (70 lb) and spacer blocks may be used to support the dummy in
position. The material should support the torso rather than the head.
Support the dummy so that there is minimum interference with the full
rotational and translational freedom for the upper torso of the dummy
and the material does not interfere with the air bag.
S24.4.3 Position 2 (head on instrument panel).
S24.4.3.1 Place the passenger seat in the full rearward seating
position. Place the seat back at the manufacturer's nominal design seat
back angle for a 50th percentile adult male as specified in S8.1.3. If
adjustable in the vertical direction, place the seat in the mid-height
position. If the seat cushion adjusts fore and aft, independent of the
entire seat, adjust the seat cushion to the full rearward position.
Position any adjustable parts of the seat that provide additional
support so that they are in the lowest or most open adjustment position.

(a) The midsagittal plane is coincident with Plane D.
(b) The legs are perpendicular to the floor pan, the back of the
legs are in contact with the seat cushion, and the dummy's thorax
instrument cavity rear face is 6 degrees forward of vertical. If it is
not possible to position the dummy with the legs in the prescribed
position, rotate the legs forward until the dummy is resting on the seat
with the feet positioned flat on the floor pan and the back of the legs
are in contact with the front of the seat cushion. Set the transverse
distance between the longitudinal centerlines at the front of the
dummy's knees at 112 to 117 mm (4.4. to 4.6 in), with the thighs and the
legs of the dummy in vertical planes.
(c) The upper arms are parallel to the torso and the hands are in
contact with the thighs.
S24.4.3.3 Move the seat forward, while maintaining the thorax
instrument cavity rear face orientation until any part of the dummy
contacts the vehicle's instrument panel.
S24.4.3.4 If dummy contact has not been made with the vehicle's
instrument panel at the full forward seating position of the seat, slide
the dummy forward on the seat until contact is made. Maintain the thorax
instrument cavity rear face orientation, the height of the dummy, and
the angle of the thigh with respect to the horizontal.
S24.4.3.5 If head/torso contact has not been made with the
instrument panel, maintain the angle of the thighs with respect to the
horizontal while applying a force towards the front of the vehicle on
the spine of the dummy between the shoulder joints until the head/torso
comes into contact with the vehicle's instrument panel.
S24.4.3.6 If necessary, material with a maximum breaking strength of
311 N (70 lb) and spacer blocks may be used to support the dummy in
position. Material should support the torso rather than the head.
Support the dummy so that there is minimum interference with the full
rotational and translational freedom for the upper torso of the dummy
and the material does not interfere with the air bag.
S24.4.4 Deploy the right front outboard frontal air bag system. If
the frontal air bag system contains a multistage inflator, the vehicle
shall be able to comply with the injury criteria at any stage or
combination of stages and at any time delay between successive stages
that could occur in a rigid barrier crash at speeds up to 26 km/h (16
mph) under the test procedure specified in S22.5.
S25 Requirements using an out-of-position 5th percentile adult
female dummy at the driver position.
[[Page 543]]
S25.1 Each vehicle certified as complying with S14 shall, at the
option of the manufacturer, meet the requirements specified in S25.2 or
S25.3 under the test procedures specified in S26 or S28, as appropriate.
S25.2 Option 1--Dynamic automatic suppression system that suppresses
the air bag when the driver is out of position. (This option is
available under the conditions set forth in S27.1.) The vehicle shall be
equipped with a dynamic automatic suppression system for the driver air
bag which meets the requirements specified in S27.
S25.3 Option 2--Low risk deployment. Each vehicle shall meet the
injury criteria specified by S15.3 of this standard, except as modified
in S25.4, when the driver air bag is statically deployed in accordance
with both of the low risk deployment test procedures specified in S26.
S25.4 Neck injury criteria driver low risk deployment tests. When
measuring neck injury in low risk deployment tests for the driver
position, each of the following neck injury criteria shall be met.
(a) Nij.
(1) The shear force (Fx), axial force (Fz), and bending moment (My)
shall be measured by the dummy upper neck load cell for the duration of
the crash event as specified in S4.11. Shear force, axial force, and
bending moment shall be filtered for Nij purposes at SAE J211/1 rev. Mar
95 Channel Frequency Class 600 (see S4.7).
(2) During the event, the axial force (Fz) can be either in tension
or compression while the occipital condyle bending moment (Mocy) can be
in either flexion or extension. This results in four possible loading
conditions for Nij: tension-extension (Nte), tension-flexion (Ntf),
compression-extension (Nce), or compression-flexion (Ncf).
(3) When calculating Nij using equation S25.4(a)(4), the critical
values, Fzc and Myc, are:
(i) Fzc = 3880 N (872 lbf) when Fz is in tension
(ii) Fzc = 3880 N (872 lbf) when Fz is in compression
(iii) Myc = 155 Nm (114 lbf-ft) when a flexion moment exists at the
occipital condyle
(iv) Myc = 61 Nm (45 lbf-ft) when an extension moment exists at the
occipital condyle.
(4) At each point in time, only one of the four loading conditions

S26 Procedure for low risk deployment tests of driver air bag.
S26.1 Each vehicle that is certified as complying with S25.3 shall
meet the requirements of S25.3 and S25.4 with the 49 CFR Part 572
Subpart O 5th percentile adult female dummy in both of the following
positions: Driver position 1 (S26.2) and Driver position 2 (S26.3).
S26.2 Driver position 1 (chin on module).
S26.2.1 Adjust the steering controls so that the steering wheel hub
is at the geometric center of the locus it describes when it is moved
through its full range of driving positions. If there is no setting at
the geometric center, position it one setting lower than the geometric
center. Set the rotation of the steering wheel so that the vehicle
wheels are pointed straight ahead.
S26.2.2 Locate the vertical plane parallel to the vehicle
longitudinal axis which passes through the geometric center of the
opening through which the driver air bag deploys into the occupant
compartment. This is referred to as ``Plane E.''
S26.2.3 Place the seat in the full rearward seating position. If
adjustable in
[[Page 544]]
the vertical direction, place the seat in the mid-height position. If
the seat cushion adjusts fore and aft, independent of the entire seat,
adjust the seat cushion to the full rearward position. If the seat back
is adjustable, place the seat back at the manufacturer's nominal design
seat back angle for a 50th percentile adult male as specified in S8.1.3.
If the seat cushion contains an independent seat cushion angle
adjustment mechanism, adjust the seat cushion angle to the middle of the
range of seat cushion angles. Position any adjustable parts of the seat
that provide additional support so that they are in the lowest or most
open adjustment position. Position an adjustable head restrain in the
lowest position.
S26.2.4 Place the dummy in the driver's seat such that:
S26.2.4.1 The midsagittal plane is coincident with Plane E.
S26.2.4.2 The legs are perpendicular to the floor pan and the back
of the legs are in contact with the seat cushion. The legs may be
adjusted if necessary to achieve the final head position.
S26.2.4.3 The dummy's thorax instrument cavity rear face is 6
degrees forward (toward the front of the vehicle) of the steering wheel
angle (i.e., if the steering wheel angle is 25 degrees from vertical,
the thorax instrument cavity rear face angle is 31 degrees).
S26.2.4.4 The initial transverse distance between the longitudinal
centerlines at the front of the dummy's knees is 160 to 170 mm (6.3 to
6.7 in), with the thighs and legs of the dummy in vertical planes.
S26.2.4.5 The upper arms are parallel to the torso and the hands are
in contact with the thighs.
S26.2.5 Maintaining the spine angle, slide the dummy forward until
the head/torso contacts the steering wheel.
S26.2.6 While maintaining the spine angle, adjust the height of the
dummy so that a point on the chin 40 mm below the center of the mouth
(chin point) is in the same horizontal plane as the geometric center of
the opening through which the air bag deploys into the occupant
compartment. If the seat prevents the chin point from being in the same
horizontal plane, adjust the dummy height to as close to the prescribed
position as possible.
S26.2.7 If necessary, material with a maximum breaking strength of
311 N (70 lb) and spacer blocks may be used to support the dummy in
position. The material should support the torso rather than the head.
Support the dummy so that there is minimum interference with the full
rotational and translational freedom for the upper torso of the dummy
and the material does not interfere with the air bag.
S26.3 Driver position 2 (chin on rim).
S26.3.1 Place the seat in the full rearward seating position. If
adjustable in the vertical direction, place the seat in the mid-height
position. If the seat cushion adjusts fore and aft, independent of the
entire seat, adjust the seat cushion to the full rearward position. If
the seatback is adjustable, place the seat back at the manufacturer's
nominal design seat back angle for a 50th percentile adult male as
specified in S8.1.3. If the seat cushion contains an independent seat
cushion angle adjustment mechanism, adjust the seat cushion angle to the
middle of the range of seat cushion angles. Position any adjustable
parts of the seat that provide additional support so that they are in
the lowest or most open adjustment position. Position an adjustable head
restraint in the lowest position.
S26.3.2 Adjust the steering controls so that the steering wheel hub
is at the geometric center of the locus it describes when it is moved
through its full range of driving positions. If there is no setting at
the geometric center, position it one setting lower than the geometric
center. Set the rotation of the steering wheel so that the vehicle
wheels are pointed straight ahead.
S26.3.3 Locate the vertical plane parallel to the vehicle
longitudinal axis which passes through the geometric center of the
opening through which the driver air bag deploys into the occupant
compartment. This is referred to as ``Plane E.''
S26.3.4 Place the dummy in the driver's seat position such that:
S26.3.4.1 The midsagittal plane is coincident with Plane E.
S26.3.4.2 The legs are perpendicular to the floor pan and the back
of the
[[Page 545]]
legs are in contact with the seat cushion. The legs may be adjusted if
necessary to achieve the final head position.
S26.3.4.3 The dummy's thorax instrument cavity rear face is 6
degrees forward (toward the front of the vehicle) of the steering wheel
angle (i.e., if the steering wheel angle is 25 degrees from vertical,
the thorax instrument cavity rear face angle is 31 degrees).
S26.3.4.4 The initial transverse distance between the longitudinal
centerlines at the front of the dummy's knees is 160 to 170 mm (6.3 to
6.7 in), with the thighs and legs of the dummy in vertical planes.
S26.3.4.5 The upper arms are parallel to the torso and the hands are
in contact with the thighs.
S26.3.5 Maintaining the spine angle, slide the dummy forward until
the head/torso contacts the steering wheel.
S26.3.6 While maintaining the spine angle, position the dummy so
that a point on the chin 40 mm below the center of the mouth (chin
point) is in contact with the rim of the uppermost portion of the
steering wheel. If the dummy's head contacts the vehicle windshield or
upper interior before the prescribed position can be obtained, lower the
dummy until there is no more than 5 mm (0.2 in) clearance between the
vehicle's windshield or upper interior, as applicable.
S26.3.7 If the steering wheel can be adjusted so that the chin point
can be in contact with the rim of the uppermost portion of the steering
wheel, adjust the steering wheel to that position and readjust the spine
angle to coincide with the steering wheel angle. Position the dummy so
that the chin point is in contact with the rim of the uppermost portion
of the steering wheel.
S26.3.8 If necessary, material with a maximum breaking strength of
311 N (70 lb) and spacer blocks may be used to support the dummy in
position. The material should support the torso rather than the head.
Support the dummy so that there is minimum interference with the full
rotational and translational freedom for the upper torso of the dummy
and the material does not interfere with the air bag.
S26.4 Deploy the left front outboard frontal air bag system. If the
air bag system contains a multistage inflator, the vehicle shall be able
to comply with the injury criteria at any stage or combination of stages
or time delay between successive stages that could occur in a rigid
barrier crash at speeds up to 26 km/h (16 mph) under the test procedure
specified in S22.5.
S27 Option for dynamic automatic suppression system that suppresses
the air bag when an occupant is out-of-position.
S27.1 Availability of option. This option is available for either
air bag, singly or in conjunction, subject to the requirements of S27,
if:
(a) A petition for rulemaking to establish dynamic automatic
suppression system test procedures is submitted pursuant to Subpart B of
Part 552 and a test procedure applicable to the vehicle is added to S28
pursuant to the procedures specified by that subpart, or
(b) A test procedure applicable to the vehicle is otherwise added to
S28.
S27.2 Definitions. For purposes of S27 and S28, the following
definitions apply:
Automatic suppression zone or ASZ means a three-dimensional zone
adjacent to the air bag cover, specified by the vehicle manufacturer,
where the deployment of the air bag will be suppressed by the DASS if a
vehicle occupant enters the zone under specified conditions.
Dynamic automatic suppression system or DASS means a portion of an
air bag system that automatically controls whether or not the air bag
deploys during a crash by:
(1) Sensing the location of an occupant, moving or still, in
relation to the air bag;
(2) Interpreting the occupant characteristics and location
information to determine whether or not the air bag should deploy; and
(3) Activating or suppressing the air bag system based on the
interpretation of occupant characteristics and location information.
S27.3 Requirements. Each vehicle shall, at each applicable front
outboard designated seating position, when tested under the conditions
of S28 of this standard, comply with the requirements specified in S27.4
through S27.6.
[[Page 546]]
S27.4 Each vehicle shall be equipped with a DASS.
S27.5 Static test requirement (low risk deployment for occupants
outside the ASZ).

dummy). Each vehicle shall meet the injury criteria specified in S15.3
of this standard when the driver air bag is deployed in accordance with
the procedures specified in S28.1.
S27.5.2 Passenger (49 CFR Part 572 Subpart P 3-year-old child dummy
and 49 CFR Part 572 Subpart N 6-year-old child dummy). Each vehicle
shall meet the injury criteria specified in S21.5 and S23.5, as
appropriate, when the passenger air bag is deployed in accordance with
the procedures specified in S28.2.
S27.6 Dynamic test requirement (suppression of air bag for occupants
inside the ASZ).
S27.6.1 Driver. The DASS shall suppress the driver air bag before
the head, neck, or torso of the specified test device enters the ASZ
when the vehicle is tested under the procedures specified in S28.3.
S27.6.2 Passenger. The DASS shall suppress the passenger air bag
before head, neck, or torso of the specified test device enters the ASZ

S29 Manufacturer option to certify vehicles to certain static
suppression test requirements using human beings rather than test
dummies.
S29.1 At the option of the manufacturer, instead of using test
dummies in conducting the tests for the following automatic suppression
and occupant recognition parts of the low risk deployment test
requirements, human beings may be used as specified. If human beings are
used, they shall assume, to the extent possible, the final physical
position specified for the corresponding dummies for each test.
(a) If a manufacturer decides to certify a vehicle using a human
being for a test of the passenger automatic suppression, it shall use
humans for the entire series of tests, e.g., 3-year-old children for
each test of the system involving 3-year-old test dummies. If a
manufacturer decides to certify a vehicle using a test dummy for a test
of the system, it shall use test dummies for the entire series of tests,
e.g., a Hybrid III 3-year-old child dummy for each test of the system
involving 3-year-old child test dummies.
(b) For S19.2, instead of using the 49 CFR Part 572 Subpart R 12-
month-old child dummy, a human child who weighs between 8.2 and 9.1 kg
(18 and 20 lb), and who is between 61 and 66 cm (24 and 26 in) tall may
be used.
(c) For S19.2, instead of using the 49 CFR Part 572 Subpart K
newborn infant dummy, a human child who weighs between 8.2 and 9.1 kg
(18 and 20 lb), and who is between 61 and 66 cm (24 and 26 in) tall may
be used.
(d) For S21.2 and S21.5.1, instead of using the 49 CFR Part 572
Subpart P 3-year-old child dummy, a human child who weighs between 13.4
and 18 kg (29.5 and 39.5 lb), and who is between 89 and 99 cm (35 and 39
in) tall may be used.
(e) For S23.2 and S23.5.1, instead of using the 49 CFR Part 572
Subpart N 6-year-old child dummy, a human child who weighs between 21
and 25.6 kg (46.5 and 56.5 lb), and who is between 114 and 124.5 cm (45
and 49 in) tall may be used.
(f) For S19.2, S21.2, and S23.2, instead of using the 49 CFR Part
572 Subpart O 5th percentile adult female test dummy, a female who
weighs between 46.7 and 51.25 kg (103 and 113 lb), and who is between
139.7 and 150 cm (55 and 59 in) tall may be used.
S29.2 Human beings shall be dressed in a cotton T-shirt, full
length cotton trousers, and sneakers. Specified weights and heights
include clothing.
S29.3 A manufacturer exercising this option shall upon request:
[[Page 547]]
(a) Provide NHTSA with a method to deactivate the air bag during
compliance testing under S20.2, S20.3, S22.2, S22.3, S24.2, and S24.3,
and identify any parts or equipment necessary for deactivation; such
assurance may be made by removing the air bag; and
(b) Provide NHTSA with a method to assure that the same test results
would be obtained if the air bag were not deactivated.
