Both pelvic-belt and shoulder-belt restraints that comply with RESNA
WC-4:2012, Section 18 and/or 4.6, 5.2, 5.3 or RESNA WC-4:2012, Section
19 should be used to limit occupant movement in a crash and reduce the
likelihood of occupant ejection from the vehicle and/or injurious contact
of the occupant with the vehicle interior.
The pelvic belt should be angled between 30° and 75° horizontally when
viewed from the side, and ideally between 45° and 75° horizontally, as
shown in the figure below.
WARNING
Back supports with adjustable recline angles should not be tilted back more
than 30° to the vertical during travel in vehicles unless necessary for the
medical and postural needs of the occupant.
WARNING
If the back support must be adjusted to an angle greater than 30° to the
vertical during travel, the upper shoulder belt anchor point should be adjusted
rearward to maintain belt contact with the wheelchair occupant’s shoulder
and chest.
