4.2 Lateral Supports (Optional)
Lateral Pads are available from Motion Concepts
as an option for additional lateral support. Lateral
Pads are offered in small, large and offset styles
(see Figure). Mounting slots in the back shell and
the lateral support brackets allow for adjustment
both vertically and laterally. Upper and lower
mounting slots are provided on the back pan for
an even greater range of adjustment. Lateral
Supports may be further customized by carefully
bending* the lateral to a more desirable contour/
position for the client. Refer to Installing Lateral
Supports.
WARNING
*For best results and to prevent damage,
the lateral supports must be removed
from the back pan prior to bending
Installing Lateral Supports
1. Pull up the bottom of the cover (release hook
and loop fasteners) to expose the mounting
slots/channels in the back pan.
2. Determine the desired mounting
height/orientation for the lateral pads (upper or
lower mounting slot position).
3. If applicable, carefully bend the lateral support(s)
to the desired contour (prior to installation).
4. Loosely install the lateral supports onto the back
pan using the hardware provided.
 Hardware can be installed in either
orientation on the back pan (with the
backing plates located on the inside
or outside of the back pan). The
standard mounting orientation is
shown at right.
5. Adjust laterals to the desired position via the
mounting slots on the backpan and via the slots
in the lateral support bracket. Secure each
lateral support into place.
6. Re-attach the back cover via the hook and loop
fasteners.
4.3 One-Hand Cord Release Mechanism
1. Thread the nylon cord through the holes in the latch mechanism at the top of the left and right
mounting plates (see image A)
2. Install the cord lock mechanism onto the cord (see image B). Press the button to open the lock
mechanism and slide the two open ends of the nylon cord through the opening.
3. With the back properly installed on the wheelchair, adjust the cord length so that it hangs at
approximately a 45° angle along the back pan (this allows the release mechanism to operate more
effectively). If necessary, cut/remove excess cord to eliminate any risk of entanglement. Once
adjusted, combine the loose cord ends into a single knot to prevent the cord-lock from slipping.
