7. SECURING THE
WHEELCHAIR
NOTE: In addition to following the general guidelines
below, be sure to follow all recommendations and
instructions provided by the WTORS manufacturer.
Figure 1. Securing the Wheelchair
30-45˚
Always secure the wheelchair
and occupant in a forward-
facing position in the vehicle.
WARNING
Attach the four tie-
down straps only to
designated, labeled
transit securement
points indicated by
anchor symbols on the
wheelchair.
See figure 1.
Tighten the straps to sufficiently remove all slack.
Never attach tie-downs to adjustable, moving, or removable
parts of the wheelchair such as armrests, front riggings,
and wheels.
Figure 2. Securing the Wheelchair
FRONT OF VEHICLE
Position the anchor points
for the rear tie-down straps
directly behind the rear
securement points on the
wheelchair. The front tie-down
straps should anchor to floor
points that are spaced wider
than the wheelchair to provide
increased lateral stability.
See figure 2.
WARNING
Always allow for
proper clear zones
when securing an
occupied wheelchair in a motor vehicle. The frontal
clear zone (FCZ) is measured from the forward
most point on the occupant’s head and should
measure at least 26 in. (66 cm) if both a pelvic and
upper-torso belt are used. See figure 3.
NOTE: The recommended frontal clear zone may not be
achievable for wheelchair-seated vehicle operators.
The rear clear zone (RCZ) is measured from the rearmost
point on the occupant’s head and should measure at least
16 in. (40.64 cm). See figure 3.

CENTER
The seated head height (HHT) ranges from about 47 in.
(120 cm) for a small adult female to about 61 in. (155 cm)
for a tall adult male.
See figure 3.
WARNING
Allow as much clearance as possible around the
wheelchair occupant to reduce the possibility
of contact with vehicle components and other
passengers in the event of a crash.
WARNING
Ensure all vehicle components that are in close
proximity to the wheelchair occupant are removed
or covered with dense padding.
