5.4.10 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
32
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.

5.4.11 Adjusting the seat depth

CAUTION!
Increased risk of tipping because of too short
seat depth
With seat depths below 41 cm, the tipping stability of
the wheelchair gets worse and there is a higher risk, in
certain situations, of falling onto the anti-tipping wheels.
– Choose a seat depth of at least 41 cm.
– Shorter seat depths are prevented by a tightly fastened
screw on the seat profile. NEVER remove this screw.
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.
