5.9.10 Adjusting the seat width
The telescopic seat support can be adjusted in four stages.
The seat width can thus be adjusted together with the
adjustable seat plate or the adjustable sling seat.
The description of how the width is adjusted is contained in
the service instructions for this mobility device. The service
instructions can be ordered from Invacare. However, they
contain instructions for specially trained service technicians
and describe operations that are not intended for the end
user.
5.9.11 Adjusting the seat depth
The seat depth has a major influence on the selection
of the center of gravity of the seat. This impacts its
dynamic stability. If you make a major change to the
seat depth the center of gravity of the seat must also
be adjusted. See "Adjusting the center of gravity of
the seat" in the service instructions for this mobility
device. The service instructions can be ordered from
Invacare. However, they contain instructions for
specially trained technicians and describe operations
that are not intended for the end user.
The numbers on the scale on the seat serve as a
guide. They do not stipulate any dimensions such as
seat depth in centimeters.

1. On both sides, loosen the bottom backrest screw A.
Do not remove the screws!
2. Move the backrest to the required seat depth.
You can adjust the seat depth steplessly. Use scale B
on the seat as a guide for this purpose.
Ensure that the same seat depth is set on both sides.
3. Re-tighten the screws.
5.10 Adjusting the seat angle
CAUTION!
Adjusting the seat tilt or the backrest angle
changes the geometry of the mobility device
and directly influences its dynamic stability!
– For details regarding dynamic stability,
negotiating gradients and obstacles and the
correct adjustment of seat tilt or backrest
angle, refer to 6.5 Taking Obstacles, page 91
and Driving up and down gradients.
