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 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 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. 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 [[Page 501]] 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 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.

Each application for a temporary exemption from the inflatable restraint requirement must include: (a) A clear and specific identification of any component in the inflatable restraint system that has become unavailable due to circumstances beyond the manufacturer's control, and a diagram showing the location of such component within the restraint system and within the vehicle; (b) A clear and specific explanation of the cause or causes of the disruption in the supply of the component, and a showing that such disruption is beyond the control of the manufacturer; (c) An estimate of the length of time that will be needed to correct the disruption and again incorporate the subject components into current production, or an explanation of why it is not possible to provide such an estimate; (d) A complete statement of the bases for the manufacturer's belief that NHTSA should grant a temporary exemption in response to this application; (e) An unconditional statement by the manufacturer that it will recall every vehicle for which a temporary exemption is requested in the application, to install all missing inflatable restraint systems; (f) A plan setting forth steps the manufacturer will take to ensure that as many exempted vehicles as possible will be returned for 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 by the manufacturer), or an explanation of why it is not possible to 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. S12.7 Labels and written notice announcing temporary exemption. S12.7.1 It shall be a condition of every temporary exemption from the inflatable restraint requirement that the manufacturer of exempted vehicles comply with the provisions of S12.7.2 and S12.7.3. S12.7.2 (a) The manufacturer of any vehicle granted a temporary exemption from the inflatable restraint requirement shall affix a label within the passenger compartment of such vehicle. The label shall set forth the following information in block capital letters and numerals not less than three thirty-seconds of an inch high: THIS VEHICLE DOES NOT CONTAIN AN AIR BAG IN CONFORMANCE WITH THE FEDERAL MOTOR VEHICLE SAFETY STANDARD FOR OCCUPANT CRASH PROTECTION. IT WAS EXEMPTED PURSUANT TO NHTSA EXEMPTION NO. (insert number assigned by NHTSA). (b) This label shall not be removed until after the vehicle manufacturer has recalled the vehicle and installed an inflatable restraint system at those seating positions for which it was granted an exemption. S12.7.3 The manufacturer of any vehicle that is delivered without an inflatable restraint system, pursuant to a temporary exemption granted under this section, shall, at the time of delivery of the vehicle, provide a written notice to the dealer to whom the vehicle is delivered. The manufacturer shall also provide a written notice by registered mail to the first purchaser of the vehicle for purposes other than resale, within two weeks after purchase. Unless otherwise provided for by the Administrator in the exemption, such notice shall provide the following information: (a) This vehicle does not conform to Federal Motor Vehicle Safety Standard No. 208, because it is not equipped with an inflatable restraint at (insert the affected seating positions). (b) The vehicle was allowed to be sold pursuant to NHTSA Exemption No. (insert appropriate exemption number). (c) The reason this vehicle was exempted from the requirement for an inflatable restraint was because of factors beyond the manufacturer's control. (d) The manufacturer will recall this vehicle not later than (insert the time set forth in the exemption) and install the missing inflatable restraint at no charge. (e) If the reader has any questions or would like some further information, he or she may contact the manufacturer at (insert an address and telephone number). S13. Alternative unbelted test for vehicles manufactured before September 1, 2001. S13.1 Instrumentation 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 Society of Automotive Engineers (SAE) Recommended Practice J211/1 MAR 95, Instrumentation for Impact Test--Part 1--Electronic Instrumentation. SAE J211/1 MAR 95 is incorporated by reference and thereby is made part of this standard. The Director of the Federal Register approved the material incorporated by reference in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. A copy may be obtained from SAE at Society of Automotive Engineers, Inc., 400 Commonwealth Drive, Warrendale, PA 15096. A copy of the material may be inspected at NHTSA's Docket Section, 400 Seventh Street, S.W., room 5109, Washington, DC, or at the Office of the Federal Register, 800 North Capitol Street, N.W., Suite 700, Washington, DC. The accelerometer sensitive axis is parallel to the direction of test platform travel. The total change in velocity (Delta V) shall be determined from the integration of the entire acceleration versus time curve from the sled. The Delta V shall include the period of time in which the sled is accelerating to 0.5 g. All points on the acceleration versus time curve at and beyond 0.5 g must be contained within or on the corridor defined in Figure 6. The agency may shift the curve with respect to time in order to fit the curve within the corridor. 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 S8.1.8.2, placed in each front outboard designated seating position as specified in S11, shall meet the injury criteria of S6.1, S6.2, S6.3, S6.4, 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 Sec. 13.1, 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. 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 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.
