A GENERAL GUIDELINES

1. Safety and operating limits

For a safe operation of your wheelchair, the following
parameters 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 transfer
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 wheelchair 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 127 kg.

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).
