If possible and feasible, the rider should transfer to the (OEM)
Original Equipment Manufacturer vehicle seat and use the vehicle restraint.
If the seating system is used for transport, it must be used in a forward-
facing seating position during travel in a motor vehicle.
The recommended clear zones for wheelchair seated occupants restrained
by both pelvic and upper-torso belt(s) and only by a pelvic belt are shown
in the diagrams
(Fig

and 3.2)
and described below. Frontal Clear Zones
(FCZ) need to be larger when upper torso belt(s) are not used. The
Rear Clear Zone of 16" (40.5 cm) is measured from the rearmost point on
an occupant’s head. The Frontal Clear zone is measured from the front
most point of an occupant’s head and is 26" (66 cm) with pelvic and upper-
torso belt(s) and 37" (94 cm) with only a pelvic belt. The frontal clear zone
may not be achievable for wheelchair- seated drivers.
4. The estimated seated height (HHT) from the ground or floor to the top of
the wheelchair-seated occupant’s head ranges from approximately
47" (119 cm) for a small adult female to about 61" (155 cm) for a
tall adult male

or 350 lbs
(160 kg)
for

Attach WTORS to securement points in accordance with the
manufacturer’s instructions and SAE J2249.
Ensure hip guides are mounted and are locked in place.
Use only Wheelchair Tie-down and Occupant Restraint Systems
(WTORS) which meet the requirements of SAE J2249 Recommended
Practice– Wheelchair Tie-down and Occupant Restraint Systems For Use
in Motor Vehicles. Do not use WTORS designed to rely on the wheelchair
structure to transfer occupant restraint loads to the vehicle.
9. In order to reduce the potential of injury to vehicle occupants,
wheelchair-mounted accessories, such as trays and respiratory
equipment, should be removed from the seating and wheelchair and
secured separately.
10. Postural supports and positioning devices should not be relied on for
occupant restraint.
11. Do not alter or substitute wheelchair frame parts, components or
seating.
12. Sudden stops or impacts can structurally damage your system. Chairs
involved in such incidents should be replaced.

Attach occupant restraints in accordance with the manufacturer’s
instructions and SAE J2249.
Both pelvic and upper torso restraint belts must be used to restrain the
occupant to reduce the possibility of head and chest impacts with the
vehicle components and serious risk of injury to the user and other
vehicle occupants
(

)
.
The upper torso restraint belt
(A)
should be mounted to the vehicle (B)
pillar
-
failure to do so will increase the risk of serious abdominal injuries
to the
user
(Fig. 3.3).
A head restraint suitable for transportation must be fitted and suitably
positioned at all times during transportation.
The pelvic restraint belt (C) must be worn low across the front of the
pelvis so that the angle of the pelvic belt is within the preferred zone of
30 to 75 degrees to the horizontal
(Fig. 3.3).
A steeper (greater) angle within the preferred zone is desirable, closer to,
but not exceeding 75 degrees
(Fig. 3.5).
19.
The upper torso restraint belt (A) must fit over the shoulder and
across the chest
(Fig. 3.3).
20.
Restraint belts must be adjusted as tightly as possible consistent with
user comfort, and should not constrict breathing
(Fig. 3.4).
