Modular Cushion
1. Add trochanter support (head of femur) wedges (A)
: these are positioned
directly behind the pre-ischial shelf (Measurement H) to provide stability
and a means of correction/accommodation for an uneven pelvis (pelvic
obliquity). Adjust the width between these to suit the needs of the user.
One may be eliminated to address uneven pelvis (pelvic obliquity) issues.
2. Add adduction (B) and abduction (C) wedges
—IF required: In some cases
these may require alteration such as narrowing of the adductor wedges
(B)
or abductor pommel
(C)
. Use the shorter wedges where shorter seat depth
is required (Measurement B) - these can also be cut down if required.
3. Assemble cushion
—install foam overlay with loop fabric on underside
attaching to base panel of cushion. The black wipe down cover is installed
and then the breathable fabric cover (if supplied)
4. Install onto seat frame;
ensure there is hook attachment on the seat
panel to hold the cushion in place, line the front of the cushion up on the
seat pan overhanging the edge by approximately 10mm (0.4 inches).
5. Install new extended Z brackets on Hip pads;
these allow for the extra
thickness of the modular cushion. Remove hip pad fasteners
(D)
and
mounting point
(E)
and replace with the new extended Z bracket assembly.
