WARNING
A three-point, vehicle-anchored, pelvic and upper torso belt occupant restraint system must be
properly installed and worn while riding in your TiLite ZRA Series 2 wheelchair in a motor vehicle.
I
WARNING
A side-view pelvic-belt angle of 30° to 75° to the horizontal (see Figure 14-4) is preferred to lower
pelvic belt angles.
I
WARNING
Always ensure that the vehicle-anchored pelvic and upper torso belt buckles are positioned so
that the release buttons will not be contacted by wheelchair components during a crash.
1. Carefully inspect the vehicle-anchored occupant restraint system belts, brackets and clamps to ensure that they
are properly secured to the vehicle and are not damaged or worn.
2. Secure the wheelchair occupant using the vehicle-anchored pelvic belt and vehicle-anchored upper torso belt.
See Figure 14-4. It is imperative that you position the belts properly. Paragraphs 3 to 7 which follow explain how
to properly position your vehicle-anchored restraint belts.
3. The pelvic belt should 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° to the horizontal. See Figure 14-4. A steeper (greater) angle within the preferred
zone is desirable.

pelvic Belt Angle
Note:
Steeper side-view pelvic-belt angles are especially important if the pelvic belt is intended to be used for
postural support in addition to occupant restraint in a frontal crash. Steeper angles will reduce the tendency
for a vertical gap to develop between the user and the belt due to compliance of seat cushions and belt
movement, thereby reducing the tendency for the user to slip under the belt and for the belt to ride up on the soft
abdomen during normal use.
