Attaching to the Permobil Unitrack is preferred, but not all Corpus chairs have it installed.
Illustration of attaching an Adapter Plate 4 to the Unitrack.
Corpus with thigh support bracket in place. No Unitrack.
Corpus frame shown with the thigh support hardware removed.
Note the holes used for attaching the thigh support. These will be used in attaching the Adapter Plate and reattaching the thigh support.
6mm bolts and spacers (supplied) are used to sandwich the Adapter Plate between the thigh support bracket and frame. (AP2 shown)
The Solid Wheelchair bracket then attaches to the Adapter Plate.
The Adapter Plate can be positioned further forward to offer an alternate Wheelchair Bracket position. Other offsets may be used, as well.

Offset options

Offsets attach to the wheelchair attachment hardware, and are used to:

  • Get around obstacles such as trays, brakes, footrests and armrests
  • Position the Wheelchair Bracket so the post is in the optimal position (post can be inserted and removed, brakes are unobstructed, footrests removed, accommodate the tray, etc)
  • Adjust the angle of the hardware and/or bracket to make sure the post is vertical

These plates can all be used to offset. To figure out which offset plate will work for you, see our Offset Guide.

How to mount: 

When there is no Unitrack and there is a thigh support bracket, the bracket may be removed. An Adapter Plate 2 or 4 is sandwiched between the thigh support bracket and the wheelchair frame, as shown in the photos. Holes on the AP4 and AP2 correspond to the Corpus holes. The Wheelchair Bracket may be attached to the AP2 or AP4, or offsets such as the L-angle Extension plate and Adapter Plates are used as needed.
