Note for Folding Chair Users
If your new Back does not easily slide into the brackets, or easily disengage
from the brackets, or if the clips on the brackets do not fully engage the Back:
Loosen the screws on hose clamps just enough to allow the bracket to move
slightly on the post without sliding down. Place the Back in the brackets and
rotate the brackets around the post to move clips forward or back until the
Back easily engages from the brackets. Several trial positions may be required
to find the best position.
Adjust Back Angle
Many wheelchairs have a backward angle bend in the back posts. Depending
on the severity of this angle, your Back may recline too far.
To compensate for this recline—or to sit yourself more vertically—your Jay
Active Back comes with a foam wedge.To use this wedge, remove the covered
foam Back from the plastic shell, open the rear zipper, and insert the wedge
inside the cover with the thick edge to the top. (Once in place, the bottom edge
of foam wedge will align with zipper.) Re-attach foam back onto plastic shell.
If this wedge does not sit you vertically enough, you still have a few options:
insert the lumbar shim behind the wedge, or order vertical posts for your
wheelchair (if they have a bend in them).
Adjust Lumbar Support
Your Jay Active Back already has a small lumbar curve built into it. However,
most people benefit from added lumbar support for straighter sitting and
reduced back pain.
To evaluate the benefits of added lumbar support, attach a piece of masking
tape on one side of the foam Back to indicate the height of your belt-line
(where most people want their lumbar support).
Detach the foam from the plastic shell. Open the back zipper, and insert the
lumbar insert with the maximum thickness of the insert against the foam Back,
at the belt-line height you indicated on the foam Back. Re-attach the foam
Back against the back shell and evaluate lumbar support. Re-adjust lumbar
height up or down if it feels uncomfortable. (You may also add more lumbar
support by inserting the lumbar shim behind the lumbar support.)
Hint: Give yourself time to get accustomed to the lumbar support. Over the
long term, it can help prevent a lot of back pain, while enhancing your sitting
stability and sitting you taller in your wheelchair.
Screwing Post Clips to your Wheelchair
Once you are satisfied with the Jay Active Back and its performance in your
wheelchair, you should screw the post clips to the wheelchair. Mark the posts
with a pen or pencil through the screw holes in the post clip. Using a hammer
and nail punch, put a dent on the mark to help guide your drill bit.
Installation of a 10-32 thread rivnut in the posts is highly recommended. If you
are not installing a rivnut, drill a 5/32" (4mm) hole at the points indicated.
(Drill only through the rear wall of the post.) Tap these holes with the silver
tapping screw provided. (To tap thread, simply screw the silver screw in once
and remove.) Once hole is tapped, use the black screws and washers provided
to permanently secure the clip to each wheelchair post.) Once screws are
installed, remove the hose clamps.
To Mount on Rigid Wheelchairs
On non-folding, rigid wheelchairs, the Jay Active Back may be permanently
mounted to the upright posts with the screws and washers provided. Please
follow the separate instructions and use the mounting hardware provided in
place of the quick release brackets.
