6.9 Tension Adjustable Seat Upholstery (Fig. 76)
If the seat fabric has stretched due to extended use, the upholstery can be re-adjusted to restore
optimal pressure distribution of the thighs.
Loosen the hook and loop connection under the seat fabric. Re-tighten the upholstery and secure
this position using the hook and loop fastener.
Unfold the wheelchair. The cross brace must be seated fully in the support guides.
6.10 Adapting the Back Upholstery (Fig. 77)
You can adjust the back upholstery in segments according to your needs.
To do this, remove the back upholstery padding and undo the hook and loop fasteners of the
straps (Fig. 77).
Reposition the straps as desired, attach them again with the hook-and-loop fasteners and cover
with the padding.
The contours of the adjustable back will result from the user’s individual requirements.
Please do not make the straps too taut to allow for some play. A well adjusted back provides
lasting comfort for the wheelchair user and reduces the risk of secondary damages and pres-
sure zones.
See to it that the user's pelvis is positioned as far posterior in the wheelchair as pos-
sible, i.e. between the back tubes. Especially in the lower section (pelvis) the padding must have
sufcient sag.
