6.1 HEAD SUPPORT ATTACHMENT (OPTIONAL)
All Matrx PB backs contain a built-in headrest plate (A) which can be used for attaching optional
head supports. Two sets of headrest clamp mounting holes (B) are provided in order to install most
standard types of headrests
CAUTION!
The headrest plate is recessed into the back pan to prevent hardware from protruding
into the back cushion. Ensure that the hardware from the headrest clamp does not extend
beyond this recessed area.

NSTALLING A EADREST
1. Open (pull down) cover and determine the appropriate set of
mounting holes for the headrest clamp.
2. Close the cover and carefully punch holes through the cover
fabric that correspond with the determined mounting holes for the
headrest clamp.
3. Open and pull down the top half of the cover/foam (enough to
access the appropriate mounting holes on the headrest plate).
4. Place the headrest clamp (not shown) on the outside of the PB Back
and push the mounting screws outward through the headrest plate.
5. Secure the headrest clamp into place and close the cover.
6.3 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 (A)
2. Install the cord lock mechanism onto the cord (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 35-45° angle along the back pan (C) (this allows the release mechanism to oper-
ate 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 (D).

If the cord length was modified, carefully melt
the ends of the cord to prevent fraying.
