Backrest

Angle-adjustable back
The backrest angle is adjusted by altering the position of the pin
in the backrest mounting. The pin (1) must be completely clicked
into place in the hole pattern on both sides, this gives you an
angle adjustment of 8.5°.
Fit the black plastic pins into the unused holes. To reach a
smaller angle increment (3.5°), you open the Allen key screw (2)
and re-set the screw into the second hole. Please use the
relevant torque force (see matrix) to tighten the screw (2).
This gives you 12° change in the back angle. Then move the pin
(1) in the opposite direction to the next hole, which gives you 12°
- 8.5°= 3.5° change. (Fig. 4.21)
To reduce the play in the backrest, the nut (1) can be released,
then the optimal position can be set using the set screw (2).
Then re-tighten the nut (1). (Fig. 4.22).
CAUTION!
The screws must be re-tightened. Otherwise the angle
adjustment will be lost.
Folding Backrest
Release the backrest by pulling the cord. At the same time, push
it forward to fold it down. To return the backrest to its original
position, this must be pulled back as far as possible until it locks
into place on both sides.

Adjustable Back Sling
The adjustable back sling can be adjusted for tension by using
several straps.
The back sling upholstery can be accessed from the inside via
an opening and can be padded to suit individual tastes, (Fig.
4.23).
Height-adjustable backrest
The backrest may be set to various back heights, in 25 mm
steps. The adjustment ranges are 250 - 300 mm, 300 - 350 mm,
350 - 400 mm and 400 - 450 mm. Release the screws (1+2) and
set the backrest to the desired height. Tighten up the screws
again (see the page on torque). (Fig. 4.24)
CAUTION!
Please note that the tipping behaviour of the wheelchair will
change if the backrest angle or backrest upholstery has been
changed. This may mean that you need to use anti-tip tubes.
