The angle of the pelvic belt should be within the preferred
zone of 30 to 75 degrees to the horizontal OR within the
optional zone of 45 to 75 degrees to the horizontal.
Steeper side-view pelvic belt angles are especially important
if the pelvic belt is intended to be used for postural support
in addition to occupant restraint in a frontal crash. Steeper
angles will reduce the tendency for a vertical gap to develop
between the user and the belt due to compliance of seat
cushions and belt movement, thereby reducing the tendency
for the user to slip under the belt and for the belt to ride
up on the soft abdomen during normal use
Steeper belt angles also reduce the tendency for upper-torso
belts to pull the pelvic belt onto the abdomen during frontal
impact loading.
DO NOT position belts OUTSIDE of armrest, wheels, etc.
DO position belts INSIDE of armrests, wheels, etc.
1. The pelvic belt should be worn low across the front of
the pelvis in contact with the tops of the thighs near
the thigh-abdominal junctions.
2. Upper-torso belts should fit directly over, and in contact
with, the middle of the shoulder.
3. The junction of the shoulder belt and pelvic belt of
the three-point belts should be located near the hip
opposite the shoulder over which the diagonal belt
crosses and not near the midline of the occupant.
