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.
The benefit of attaching to the armrest on a standing wheelchair is that a person's device remains in the same position relative to them and their access method, whether it is eye gaze or hand access. While we don't usually suggest attaching to armrests, standing wheelchair armrests are more stable.
Newer Permobils offer Unitrack beneath the armrest, making attachment easier. Attaching to old style armrests is possible, and shown as Approach 2
Approach 1: Attach to Unitrack on the underside of the armrest. First, attach the LAE (L-Angle Adapter Plate) to the Unitrack. Next, attach the PEK (Post Extention Kit) to the threaded holes on the L-Angle Extention Plate. In some cases a WC-AP2 or WC-AP4 can be attached to the LAE threaded holes (instead of the PEK) and then the WB2 can be attached to the WC-AP2 or WC-AP4. The PEK gives the user much more flexibility as it can be extended further out.
Follow along with owner, Peter Loeffler, as he shows three attachment methods for the F5 wheelchair. If the embedded playlist isn't working, here is a link to the YouTube videos:
The old style Permobil armrest bracket has two holes available to attach to.
Attach an Adapter Plate using these two holes. Orient the AP2 so the threaded holes are oriented to the front of the armrest. Depending on where the armrest is, and where the Solid Wheelchair (WB2) post and mounted device needs to be located, Offsets may be required. They can be used to lower the WB2, or move the post to the outside, inside or in front of the armrest.
