Adjusting The Seat Depth - Invacare Dragon Vertic User Manual

8.2

Adjusting the seat depth

To optimally adjust the wheelchair to the user's needs, it is advisable to have the seat depth
adjusted individually by an authorised Invacare® dealer.
There are perforated rails under the seat for adjusting the seat depth. This results in the following
seat depths: 38, 40, 42, 44 and 46 cm. The electric wheelchair is set at the max. seat depth of 46
cm when supplied.
CAUTION! Danger of injury
• When carrying out work underneath the raised seat unit it must be ensured that this is not
lowered. The electric wheelchair must be switched off.
CAUTION! If the seat depth is not adjusted properly, there is danger of the verticalizer
being destroyed!
• The lower and upper perforated rails of the parallelogramm must be adjusted in an analog
fashion towards each other. In the event of diversity in adjustment the verticalizer is destroyed
upon operation due to the change in geometry.
What should be observed when adjusting the seat depth?
If the seat depth adjustment is too short, the forces on the body whilst standing up are too great.
If the seat depth adjustment is too long, the user can "collapse" whilst standing up.
