WARNING: THE CHAIR MUST BE UNOCCUPIED WHEN MAKING THIS
ADJUSTMENT.
SEAT DEPTH
1. Determine if the backrest must
slide forward or backward to
provide the appropriate clearance
behind the patient’s knees.
2. Lay the chair on its side.
3.
Using a ½" (13 mm) wrench,
loosen the 4 bolts under the seat
structure that go through the slots
and that control the seat’s depth.
WARNING: DO NOT REMOVE THEM
ALL THE WAY.
4. Adjust the backrest to the desired
position by sliding both sides
at the same time so that the
backrest moves uniformly.
The seat depth adjustment (from 13 ¾
"
to 18
"
) is done according to
the length of the user’s leg. It is important that the hollow in the back of
the knee (the popliteal fossa) has proper clearance. Adjust the depth
of the seat so that your hand easily passes between the knee and the
seat cushion. This adjustment will promote good contact with the seat
and the back with the backrest.
5. When the appropriate depth is
reached and equal on both sides,
firmly tighten the 4 bolts.
6. Get the user to try it and readjust it if needed.
Slide the backrest forward or backward to adjust the seat depth.
