Positioning the Wheelchair in the Vehicle
This wheelchair must be in a forward facing 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
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-inches is measured from the
rearmost point on an occupant’s head.
The frontal clear zone is measured from the frontmost point
on an occupant’s head and is 26-inches with pelvic and
upper-torso belt(s) and 37-inches with ONLY a pelvic belt.
The frontal clear zone may not be achievable for
wheelchair-seated drivers.
The estimated seated height (HHT) from the ground or
floor to the top of the wheelchair-seated occupant’s head
ranges from approximately 47-inches for a small adult
female to about 61-inches for a tall adult male.
