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 caster 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 replaced. 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.
