Angle-Adjustable Backrests (Fig. 4.17)
The backrest can be ad just ed to 5 different positions (3°
forwards, 0°, 5°, 10°, and 15° backwards).
A plate (2) is located on the sideguard, allowing you to set the
angle by removing the screws (1) (see the page on torque).
CAUTION:
The screws (1) connect the backrest di rect ly to the frame;
screw ing them in too tightly may cause them to break.
Conversely, screws that are too loose can be easily lost. In
either case, injuries could result when using the push handles
to ascend stairs.
For your own safety, we recommend that adjustments only be
made by authorized dealers.
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.
Cambers
Backrest
Camber (Fig. 4.15 / 4.16)
The camber may be set be tween 1° and 4°. This makes it
possible to increase the chair’s lateral stability as well as its
maneuverability. Remove the axle plate screws (1). Adjust the
adap ter (2) to the desired angle. Tighten the screws. (See the
page on torque). Raising the camber also raises the overall
width of the wheelchair (by about 1 cm per degree).
CAUTION:
It may be necessary to readjust both the wheel locks and
casters.
Axle Plates (Fig. 4.14)
The position of the body’s center of gravity with respect to the
rear wheels is critical for ensuring easy and pleas ant use of the
wheelchair. Several positions are possible: Moving the axle
plate (1) backwards along the holes drilled in the frame (2) will
make the chair more stable, but it will not be as maneuverable
as it would be if the axle plate were positioned farther to the
front. You may adjust the seat height by moving the axle sleeve
(3) in the axle plate. When finished, make sure that all screws
have been properly tightened (see the page on torque).
CAUTION:
•
It may be necessary to readjust both the wheel locks and
casters.
•
Please note that the tipping behaviour of the wheelchair will
change if the COG has been changed. This may mean that
you need to use anti-tip tubes.
