Bora (non-track seat)

Invacare Bora frame (without a track)
The underside reveals two bolts used to adjust and secure the seat width. The nuts are to the inside of the leg supports.
Bolt heads, visible from the front view. (Bora shown)
Side view: the attachment bolts are just inside the footrest hangers.

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: 

This installation uses two seat width adjustment welded nuts to attach an Adapter Plate 4. The welded nuts accept M8 bolts, which fit in the large holes and wide slots on the Adapter Plate 4. Align a large hole and wide slot on the AP4 with the two weld nuts to determine how to attach it. Orient the AP4 so the threaded holes which allow attachment of an L-Angle Extension Plate point to the outside of the frame. If necessary, attach another plate to offset it prior to attaching the L-AE. Using two slightly longer bolts and two M8 nuts, thread one nut down to each of the bolt head. Place the bolts through the Adapter Plate hole and slot to be used. Thread the two remaining nuts on the bolts. Place the AP4 over the welded nuts and tighten the bolts until they secure the leg rest hardware. Once the bolts are tightened, tighten the first set of nuts down to the weld nut. Tighten the second set of nuts (between the AP4 and bolt head) to secure the AP4. Attach the L-AE to the AP4 so the vertical face of the L is outside the frame. An Angle Adjustment plate may be used between the AP4 and L-AE to reorient the L-Angle if needed. Attach the Wheelchair Bracket.
