Percentage Of Weight Distribution; Adjusting The Wheelbase For Stability - Invacare XtraTM 1026793 Operator And Maintenance Manual

Percentage of Weight Distribution

DO NOT attempt to reach objects if you have to move forward in the seat or pick
them up from the floor by reaching down between your knees.
The seat depth, seat dump, back angle, seating system, size/position of the rear
wheels, size/position of the front casters, as well as the user condition directly relate
to the stability of the wheelchair. Any change to one (1) or any combination of the
nine (9) may cause the wheelchair to decrease in stability. These adjustments
MUST be performed by a qualified technician
NOTE: For this procedure, refer to FIGURE 2.4.
Many activities require the wheelchair
owner to reach, bend and transfer in and
out of the wheelchair. These movements
will cause a change to the normal balance,
the center of gravity, and the weight
distribution of the wheelchair. To
determine and establish your particular
safety limits, practice bending, reaching
and transferring activities in several
combinations in the presence of a qualified
health professional BEFORE attempting
active use of the wheelchair.
Proper positioning is essential for your safety. When reaching, leaning, bending forward,
it is important to use the front casters as a tool to maintain stability and balance.

Adjusting the Wheelbase for Stability

NOTE: For this procedure, refer to
FIGURE 2.5.
Lengthening the Wheelbase - will increase
stability and maintain standard
maneuverability of the wheelchair.
Shortening the Wheelbase - will increase
maneuverability and distribute additional
weight onto the rear wheels.
Centering the Wheelbase - gives you
maneuverability and response.
