of the 'H point' determined by using the equipment and procedures specified in SAE J826 (Apr 80) - Devices for Use in Defining and Measuring Vehicle Seating Accommodation except that the length of the lower leg and thigh segments of the 'H point' machine must be adjusted to 414 mm and 401 mm, respectively, instead of the 50 th percentile values specified in Table 1 of SAE J826.

8.5.2.                              Pelvic angle - As determined using the pelvic angle gauge (drawing 78051-532) which is inserted into the 'H point' gauging hole of the 'Test Dummy', the angle measured from the horizontal on the 76.2 mm flat surface of the gauge must be 22.5 degrees plus or minus 2.5 degrees.

8.5.3.                              Legs -  The upper legs of the driver and passenger 'Hybrid III' 'Test Dummies' must rest against the 'Seat' cushion to the extent permitted by placement of the feet.  The initial distance between the outer knee clevis flange surfaces must nominally be 269 mm.  To the extent practicable, the left leg of the driver 'Test Dummy' and both legs of the passenger 'Test Dummy' must be in vertical longitudinal planes.  To the extent practicable, the right leg of the driver 'Test Dummy' must be in a vertical plane.  Final adjustment to accommodate placement of feet in accordance with clause 8.5.4 for various passenger compartment configurations is permitted.

8.5.4.                              Feet - The feet of the 'Hybrid III' 'Test Dummies' must be positioned as follows:

8.5.4.1.                        - Driver's right foot.  The right foot of the driver must rest on the undepressed accelerator pedal with the rearmost point of the heel on the floor surface in the plane of the pedal.  If the foot cannot be placed on the accelerator pedal, it must be set initially perpendicular to the lower leg and placed as far forward as possible in the direction of the pedal centreline with the rearmost point of the heel resting on the floor pan.  Except as prevented by contact with a vehicle surface, place the right leg so that the upper and lower leg centrelines fall, as close as possible, in a vertical plane without inducing torso movement.

8.5.4.2.                        - Driver's left foot.  The left foot must be placed 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.  If the foot cannot be positioned on the toeboard, it shall be set initially perpendicular to the lower leg and placed 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
