6.7 Adjusting the leg supports

The distance between the footplates and the sitting surface influences sitting stability. The height adjustment acts
on the pelvis and ischial bones.

6.7.1 Adjusting the lower leg length

The required leg support height depends on the lower leg length of the user and the thickness of the seat cushion.
Legrests/tube footrest on the Avantgarde DS
1) Loosen the Allen head screw on the front frame (see fig. 54).
2) Adjust the lower leg length (measurement to the top edge of the seat upholstery, see fig. 55).
INFORMATION: There are several threaded holes on the frame tube. Depending on the desired set­
ting, the Allen head screw may have to be completely removed and inserted into a different hole.
INFORMATION: There are three threaded holes in the tube foot support. These have to be aligned with
the threaded holes in the frame tube. Using one Allen head screw per tube foot support is sufficient
for installation.
3) Tighten each Allen head screw to 7 Nm.
