FITTING THE J2 DEEP CONTOUR BACK
TO THE USER
Fitting the Back Height
1. When the Back is properly adjusted, the top hooks should
rest against the wheelchair back posts.
2. Re-install the Deep Contour Back foam insert.
3. Position the user's hips to the back of the wheelchair.
4. Adjust the back height, with the top and bottom hardware
loose enough to slide on the back posts. The Back is
designed to be fit at a height that supports the pelvis in its
optimal position. In doing so, the recline feature may be
incorporated without affecting pelvic position. Typically, for
the user with little or no posterior pelvic tilt, or a flexible
posterior pelvic tilt, the Deep Contour Back is positioned so
that the bottom pins on the Back shell (Fig. 8) are at a height
that strikes a level line across the PSIS (the PSIS is near the
top, rear and central area of the pelvis (Fig. 8) or the S1-S2
level of the spine. At this point, when the Back is reclined to
open up the seat to back angle, the pelvis is supported in the
neutral position. This helps keep weight off the coccyx (tail
bone) and maintain a stable pelvis.
5. Once the proper height has been established, tighten screws
"A" on the top and bottom hardware.

Adjusting the Back Angle
To recline the Deep Contour Back,
simply turn screw "C" located at
the back of the top hook adjusters
(Fig. 9) at the rear of the Back.
Turning the screw clockwise will
make the Back more vertical.
Turning the screw counter clock-
wise will recline the Back. Hash
marks on the side of the adjuster
blocks help ensure that the Back is
evenly adjusted.

Assessing for additional lumbar support
1. Detach the Back foam insert from the Back shell. The lumbar
support Velcros directly to the Back shell behind the foam
insert.
2. Attach the lumbar support to the Back shell with the part
number (B2320W) on top, facing up (Fig. 10).
3. Re-attach the Deep Contour foam insert. Adjust as necessary.

Assessing for Posterior Lateral Lumbar Support
1. The PLLS, Posterior Lateral Lumbar Supports, are a set of
additional supports that Velcro to the Back shell adjacent and
on each side of the lumbar support. The PLLS is designed to
provide increased pelvic stability lateral of the lumbar sacral
spine area. The PLLS accessories may be moved horizontally
or vertically on the Back shell to accommodate a variety of
body shapes and sizes. The additional stability helps keep the
pelvis centrally located in the wheelchair and enhances the
Back foam contour, resulting in a more intimate fit of the
Back to the body.
2. Detach the Deep Contour Back foam from the Back shell.
Attach the PLLS accessories (Fig. 11) as necessary.
3. Re-attach the Back foam.
