6.3. Climbing stairs and high steps
•
The helpers must only take hold of securely fitted parts of the frame
(Figs. 21 and 22).

•
When going up stairs, the helper behind the wheelchair pulls the
wheelchair over the step holding it by the securely fitted handles.
•
The helper who is below the chair takes hold of the front frame
tubes and stabilises the position. At the same time, this helper
pushes the rear wheels of the wheelchair against the steps.
•
When going down stairs, the helper who is below the chair brakes
by pushing the wheelchair right against the steps. The helper who
22
is above the wheelchair holds it by the push handles, secures it and
holds it in the right position. The wheelchair should roll down step
by step.
6.3. Moving the wheelchair
Sit down in your B+B wheelchair. Make sure that you sit as far back as
possible. Moving and braking are achieved via the push rims on the
drive wheels. Make the first attempts at movement carefully until you
are used to the wheelchair and how it handles. Wheelchairs have only
limited anti-tip and anti-slip security. Particular care is advised when
braking, starting or turning on up or down gradients
22
Where steps are high and where there are stairs with
more than 3 steps, 2 assistants must
help.
The frame and the push handles are the only places
where the wheelchair can be gripped to transport it.
Under no circumstances should armrests be used to
lift the wheelchair!

Leaning an extremely long way out of the wheelchair increases the risk
of tipping over. For greater safety, all wheelchairs can be equipped with
a safety belt (not standard).
You can hang shopping bags or a rucksack on the backrest frame. To
make it easier to negotiate obstacles, staff assisting you must position
the wheelchair at a right angle to the obstacle by pressing the tip assist
with the foot (see Fig. 9).
The parking brake must be activated before getting into / out of
the wheelchair. You should only travel outside the home if you have
sufficient experience in handling the chair. If possible, there should be
someone accompanying you.
The static stability is 7° (approx. 12%) on the basic model.
The critical obstacle height* is 23 mm on the basic model in an
unfavourable situation (max. shift of centre of gravity to the back).
*The critical obstacle height is the height at which the centre of gravity
(with the user) is directly above the edge of the obstacle. If the user
tries to move the wheelchair over the obstacle by propelling the driving
wheels, without now shifting the centre of gravity forwards, then the
wheelchair will tip over backwards.
According to the German traffic regulations (STVZO
66/1) dated 1/1/1981, manually operated
wheelchairs travelling on public roads (including
pavements) must have permanently attached
illumination.
This comprises (passive):
•
two red reflectors at the back
•
two yellow reflectors on the side (on both sides).
If the wheelchair is used after dark, the following are also required
(active):
•
one white light at the front
•
one red light at the back.
The functioning of these lights must be ensured by an electrical circuit
(batteries) that is independent of the driving operation.
