Installing/Removing Seat Positioning Strap - Invacare PATRIOT Manuel De L'utilisateur Et D'entretien

SEAT/BACK
The best point of control for the pelvis is near the Pos-
terior Superior, Iliac Spine (P.S.I.S.). The upper trunk
should be relined until a balanced posture is achieved,
approximately 10 to 15 degrees (FIGURE 7).
FIGURE 7
For individuals who have fixed kyphotic spine, the backrest
can be adjusted to allow for an increased recline while
providing increased contact and support of the back (FIG-
URE 8).
FIGURE 8
The height of the backrest and the amount of control
provided by the adjustable tension upholstery will vary
depending on the abilities of the user. An active paraple-
gic (SCI) may require minimal back height which adds
posterior stability to the pelvis and lets the trunk assume
a natural balance over the top edge of the wheelchair
upholstery. A less active para (with a higher level of injury)
or a quadriplegic may require a higher backrest with an
increased level of recline (FIGURE 9).
