18.1.3 Instructions for sitting posture with
an adjustable backrest
For a good sitting posture, we recommend
positioning the backrest vertical to the ground,
where possible.
With low backrests with adaptable belt cover
due to a disability, it may be advantageous to
slightly tilt the backrest forwards and to slacken
the top belt of the backrest upholstery so that
the slack in the upper area is greater in order
to achieve good sitting stability under certain
circumstances (see Chapter 18.2).
The adjustment possibility of the backrest an-
gle supports active sitting and ensures for flex-
ibility of the wheelchair user. An example in the
following:
If the angle of the seat has been changed
(see Chapter 17), the angle of the backrest
can be respectively readjusted.
When driving on slopes and when trans-
porting baggage (e.g. backpacks) on the
backrest, the centre of gravity shifts more
to the rear and the risk of tipping increas-
es. Then this can be counteracted by a re-
spective angle adjustment of the backrest
to the front.
For comfortable seating, the backrest can
be locked in a position to the rear so that
the backrest is tilted slightly back.
18.1.4 Adjusting the backrest angle or
folding down the backrest with an
adjustable backrest
To
adjust the backrest angle
, relieve it (oth-
erwise there is a risk of tipping) and then loos-
en the locking pins that engage in the locking
holes of the side sections on the left and right.
For this purpose, grasp under the seat cover
and in the middle, pull the cord to the front that
is linked to the locking pin.
