6.6.2 Adjusting the seat upholstery

INFORMATION

You can slightly correct the centre of gravity by making small changes to the sag of the seat upholstery. Larger

corrections, however, need to be made through adjustment of the frame, slider and castor wheels.

"Standard" Seat Upholstery

This seat upholstery does not need to be adjusted during the initial fitting. If the upholstery sags significantly after

longer periods of use, it must be exchanged. To exchange it, see the 647G829 service manual.

"Adaptable" Seat Upholstery

This seat upholstery can be adjusted in segments to the needs of the user.

1) Remove the seat cushion.

2) Pull the seat pad off the hook-and-loop fastener (see fig. 46).

3) Pull the flap of the backrest pad off the hook-and-loop fastener (see fig. 42, item 2) and let it hang down.

4) Loosen the backrest straps and then fasten together with the desired tension (see fig. 47).

5) Secure the backrest pad to the seat upholstery with the hook-and-loop fastener. To do this, pull the part of the

flap that can be fastened forwards and fasten to the seat upholstery (see fig. 42, item 2).

INFORMATION: The part of the flap that can be fastened prevents sliding or falling through the gaps

between the straps and protects against draughts.

6) Fasten the seat pad (see fig. 42, item 1) and the seat cushion.

The required footrest height depends on the lower leg length of the user and the thickness of the seat cushion.

"Angle-adjustable" footrest and "Fixed" footplate

1) Slightly loosen the four clamping screws on the inner side of the castor attachment device (see fig. 48, item 1).

2) Adjust the lower leg length (continuously adjustable). The foot stirrups must be slid at least 60 mm into the

frame tube.
