F. SECURING THE OCCUPANT: WHEELCHAIR ANCHORED BELTS
WARNING
Use only a pelvic belt system that meets the requirements of ANSI/
RESNA WC-4 section 19 and SAE J2249.
The wheelchair’s referenced in this supplement are used by adults
and children who weigh more than
51 lbs (
23kg
)
and are designed
to provide for the anchoring of a pelvic belt restraint that conforms
to the requirements of ANSI/RESNA WC-4, Section 19. They can
be used in conjuntion with a vehicle-anchored shoulder belt and a
standard lower-anchorage connector as a crashworthy three-point-
belt restraint in motor vehicles.
The use of postural pelvic belts attached to the wheelchair base or
seat frame is encouraged during travel. These belts should be
positioned so that they don’t interfere with the proper positioning
of crash worthy restraints. The postural belt should NOT be relied
on for occupant protection in crash situations unless it has been
designed to comply with the requirements of ANSI/RESNA WC-4,
Section 19.
1.
Install the pelvic belt (A) and hardware
(B) onto the pelvic
belt securement point (C) anchored to the seating frame of
the wheelchair. Use a 5mm Allen head wrench and torque
to144 in-lbs when attaching the pelvic belt to the mounting
anchor (B). The pelvic belt bolt and washer (D) are generally
provided depending on your specific wheelchair.
2.
Repeat Step 1 for the opposite side.
