The optimum position for the brake with respect to the tyre
is about 0.5 cm between the tyre and the brake rod (0.6
cm if puncture-proof tyres are fitted) (see chapter 6.8
“Brakes adjustment”).
The brake works by means of a lever which acts
directly on the
tyre.
For
this
reason
the
effectiveness of the braking system depends on the
tyre being correctly inflated. We highly recommend
checking tyre pressures at regular intervals. (see
chapter 2.6 “Tyre pressures”).
The brake is a safety feature and must not be used
while the wheelchair is moving as this could cause the
wheelchair to overturn with possible injury to the
occupant.

Safety belt and harness
Both the waist belt (figure 35) and the harness (figure 36) are
accessories to this model and must therefore be ordered
separately. Both of these belt systems are designed to offer greater
security and stability to the occupant while seated in the chair.
Both the waist belt and harness system are of particular
use to occupants with little control of their upper body
and who require extra support in order to be held securely
in the seat during use
.
The waist belt (figure 36) holds the occupant in the chair around the
waist and leaves the upper body free for movement.
The waist belt is fastened to the wheelchair with two anchorage
points at the back of the frame (figure 31).
The harness system (figure 36) holds the occupant in the seat at
his/her waist and shoulder. The entire upper body of the occupant is
secured to the seat. It is intended for use by occupants with
particularly limited mobility in the upper body.
The harness system is fastened to the wheelchair with four
anchorage points on the rear of the frame (figure 32).
Using the waist belt and harness system
Using the waist belt (figures 35 - 38) and harness system (figures 36-
38) is fairly simple.
