Functional Reach From a Wheelchair
The approximate reach-limit values shown in the accom-
panying graphs were derived on the basis of a sample of
91 male and 36 female wheelchair users. Note the differ-
ence between the maximum and the comfortable reach
limits, a subjective but important consideration in design.

WARNING
Many activities require the wheelchair user to
reach, bend and transfer in and out of the wheel-
chair. These movements will cause a change to
normal balance, center of gravity, and weight dis-
tribution of the wheelchair. To determine and es-
tablish your particular safety limits, practice bend-
ing, reaching and transferring activities in several
combinations in the presence of a qualified
healthcare professional BEFORE attempting active
use of the wheelchair.
Proper positioning is essential for your safety. When
reaching, leaning, bending or bending forward, it
is important to use the casters as a tool to maintain
stability and balance.
FWD WHEELCHAIRS ONLY (FIGURE 1).
WARNING
The overall performance of the wheelchair WILL
be affected by the front wheel mounting position.
The following charts show the mounting position of
the motors for each seat width and depth depend-
ing on the factory setting or user's weight. If the
mounting position that corresponds to the user's
weight is different than the factory setting, the mo-
tors MUST BE repositioned to maintain proper stabil-
ity BEFORE using the wheelchair. Otherwise injury or
damage can occur.
Periodically review the following charts to make sure
the motor mounting position still corresponds to the
user's weight to maintain the proper stability.
Repositioning the motors MUST be performed by
an Invacare Dealer.
