7.5 Adjusting the back support upholstery / seat upholstery
7.5.1 Adjusting the back support upholstery
INFORMATION
A well-adjusted backrest provides lasting comfort for the wheelchair user and reduces the risk of secondary dam
age and pressure zones. Do not create too much pressure.
INFORMATION
Ensure that the user's pelvis is positioned as far back in the wheelchair as possible, i.e. between the backrest
tubes.
The back upholstery is attached to the frame tubes with hook-and-loop straps.
1) Fold up the backrest padding.
2) Open and loosen the hook-and-loop straps one after the other (see fig. 13).
3) Sit and position the user in the wheelchair.
4) From the bottom to the top, adjust the tension of the hook-and-loop straps to the weight and anatomical condi
tion of the user and fasten the straps (see fig. 14).
INFORMATION: The two ends of the hook-and-loop strap have to overlap by at least 100 mm in each
case.
INFORMATION: Adjust the respective lower hook-and-loop straps somewhat tighter.
INFORMATION: Deviating adjustments may be required in specific cases; this is the responsibility of
the attending therapist.
