pOSITIONING THE WHEELCHAIR IN THE VEHICLE
I
WARNING
The TiLite Aero Z or ZRA wheelchair equipped with a TiLite Transit Tie-Down Option complies
with the requirements of ISO 7176-19 and, as such, has been designed and tested for use
ONLY as a forward-facing seat in a motor vehicle. This TiLite wheelchair was not designed to be
rearward-facing or sideways-facing when used as a seat in a motor vehicle.
I
WARNING
It is imperative that the wheelchair ALWAYS be positioned in a vehicle with appropriate clear
zones around the wheelchair because in a frontal impact, even when properly secured, the
wheelchair and its occupant will move from their secured position. Clear zones are required
whether the wheelchair occupant is restrained by both pelvic and upper torso belts or only by
a pelvic belt. The use of only pelvic or only upper torso belts is highly dangerous and is never
recommended. The minimum necessary clear zones for the TiLite wheelchairs are shown in
Figure 14-3.
Figure 14-3
Clear Zones
• The rear clear zone 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.
• FCZ = 26in. (650mm) with pelvic and upper torso belts and 37-1/2in. (950mm)
with pelvic belt only.
• Seated head height (HHT ranges from about 47in. (1200mm) for a small adult
female to about 61in. (1550) for a tall adult male).

WARNING
The tie-down brackets on your wheelchair were designed, located and installed by TiLite to
comply with ISO 7176-19 and SAE J2249 standards so as to ensure that they operate properly
and maximize the performance of the brackets in a frontal impact collision. The two front Tie-
Down brackets (see Figures 14-4 and 14-5) should NEVER be removed or relocated to another
