Invacare® Bora/Spectra XTR Series

5.8.5 Adjusting Seat Depth

The seat depth has a major influence on the selection
of the centre of gravity of the seat. This impacts
its dynamic stability. If you make a major change
to the seat depth the centre of gravity of the seat
must also be adjusted. See "Adjusting the centre of
gravity of the seat" in the service manual for this
mobility device. The service manual 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.

5.9.2 Manually using spindle

The seat angle is adjusted by means of a spindle, which is
to be found at the front underneath the seat frame.
When adjusting the seat angle it should be ensured that at
least 1 cm of the threaded bolt always remains inside the
spindle and is not completely unscrewed from the spindle.
