holes on the left and right side. To do this,
pull the middle of the cord (Fig. 3 b) located
underneath the seat covering that is con-
nected to the drop-in pins.
After releasing both drop-in pins, the back-
rest can be adjusted as desired. Release
the cord to lock the backrest in position
again. Ensure that both drop-in pins are
securely fixed in the desired holes before
using the backrest.
Should the seat angle be changed, the
backrest can be re-adjusted accordingly at
any time.
When driving up inclines and transporting
luggage (e.g. rucksacks) on the backrest,
the centre of gravity is shifted to the back.
This can be compensated for by tipping
the backrest forward so that the wheelchair
does not tip backward as easily.
For comfortable sitting, the backrest can be
fixed in the last position so that it is tilted
slightly backward.
IMPORTANT
Tilting the backrest backward shifts the cen-
tre of gravity. The further back the backrest
is tilted, the sooner the point of tipping in
this direction is reached.
3.2 Sag of seat and backrest covering
The wheelchair is equipped according to
the order with the seat and backrest cover-
ing „Body Contour“ or with an adjustable
seat and backrest covering. Both types of
covering ensure excellent air circulation
which can be advantageous when used
in conjunction with a suitable cushion for
problems caused by decubitus.
3.2.1 Body Contour
The seat and backrest covering of the Body
Contour version can considerably improve
the driving comfort due to its elasticity and
in conjunction with a suitable cushion can
help to prevent decubitus. However, the
Body Contour covering cannot be adapted
to the special needs of each individual.
3.2.2 Adjustable seat and backrest cov-
ering
The adjustable seat covering comprises a
belting system. The horizontal belts can be
pulled taut by Velcro fasteners so that the
seat sag can be adjusted accordingly.

The backrest also comprises a belting
system. The sag of the backrest can be
adapted to the special requirements of each
individual. Remove the backrest cushion
and adjust the horizontal belts at the buckle
(Fig. 4 a) as required. To prevent the buckle
bar from bending, feed both belts through
the buckle. Replace the backrest cushion.
IMPORTANT
Check the tautness of the seat and back-
rest covering at regular intervals and in
case of doubt, allow the medical supplies
dealer to check its state. A tear in the seat
or backrest covering may cause accidents
with severe injuries.
Always sit down in the wheelchair slowly
to prevent the seat and backrest covering
from tearing.
3.3 Seat angle / seat height at front
Once the seat height at the back is set
as required, the seat angle and the seat
height at the front can be set accordingly.
Numerous castors and 3 different castor
forks (Fig. 5) are available for this purpose:
1-slot, 2-slot and 3-slot forks. The matching
forks are installed at the factory accord-
ing to your seat height/length of lower leg.
