A GENERAL GUIDELINES

1. Safety and operating limits

For a safe operation of your wheelchair, the following para-
meters should be observed :
- Stability and balance
Your wheelchair has been designed to provide the stability
you need during normal daily activities.
Any movement in the wheelchair will have an impact on
the position of the centre of gravity, which may lead to the
wheelchair tipping and a fall.
To improve your safety when you move a lot or you trans-
fer your weight from one place to another, we recommend
using seat belts.
- Weight distribution (figure 1)
Many actions cause the user of a wheelchair to reach out,
lean over or move about within the wheelchair and outside
it. Any movement you make whilst sat in your wheelchair
will move the combined centre of gravity (Gc) of you and
the wheelchair (Gw).You will remain stable in the wheel-
chair whilst the line of your combined centre of gravity lies
within the points of contact of the forward and rear wheels
with the ground.
- Weight Limit
The maximum recommended weight of the user is 125kg.
However, the level of activity is an essential factor. For
example, an active user who weighs 75 kg may subject the
wheelchair to more stress than user who weighs 100 kg. To
this purpose, we recommend that you consult your retailer
when choosing the model of wheelchair based upon your
daily life style.

1.1. Reaching an object from the chair

The limitations on reaching out from a wheelchair indicated
in the following diagrams have been calculated based on a
representative sample of wheelchair users:
- Only the arms should be extended beyond the seat of the
wheelchair. (figure 2).
- In any case the body and head shouldn't remain without the
boundaries of the seat. (figure 3).
