Modular Cushion
Part No. 2006-0610-0xx (xx = Colour code)
The modular cushion is designed for addressing pelvic positioning needs that
are too complex to be addressed by the flat seat cushion and the wedges
associated with it.
To configure the cushion:
1. A set of accurate user measurements should be obtained in order to set this up
correctly. Measurements we recommend are as follows:
•
Seat depth /
Measurement B
(while sitting most upright / at optimum
pelvic tilt)
•
Seat width /
Measurement A
(both at the hips and at the thighs)
•
Position for pre-ischial shelf /
Measurement H
(typically this is the line of
the gluteal crease, measured from rear of cushion)
2. Remove the covers
(A)
and the foam overlay
(B)
from the cushion to reveal the
positioning elements
(C)
.
3. Configure the pre-ischial thigh support:
•
Use a combination of 20mm (0.8 inches) thick flat sections to create the
required depth of support for thighs in front of the users IT / pelvic bones
(Measurement H).
NOTE:
One of the sections has the edge rounded off
(D)
. This must be used at the rear of
the pre-ischial shelf against the IT pelvic bones (Measurement H).
Some sections of this element may not be required due to a short seat depth. These
should be retained for introduction at a later date once the user grows.
WARNING
Interfering with the modular positioning elements inside the
cushion could present a risk to the user.
