PELVIC OBLIQUITY ADJUSTMENT (FIGURE 6)
The pelvic obliquity adjustment can be made all at one time if the user can tolerate the posi-
tioning change or can be gently changed over time. This adjustment can be made in infinite
increments, however, the maximum amount of pelvic obliquity is dependent on cushion width
and contour.

COVERS in this instruction sheet.
2. Remove the pelvic support layer from the bottom seat layer.
NOTE: The pelvic support layer is secured to the bottom seat layer with hook and loop strips.

the obliquity.
NOTE: There is a centerline on the insert and five (5) indicator marks on the seat to use as guidelines:
Neutral, Middle Right, Maximum Right, Middle Left and Maximum Left.

A. From the top of the pelvic support layer on the high side to the seat
(MEASUREMENT "A").
B. From the lower side of the pelvic support layer to the seat (MEASUREMENT "B").
5. Subtract MEASUREMENT "B" from MEASUREMENT "A" to calculate amount of obliquity
achieved.
6. Adjust pelvic support layer until desired obliquity is obtained.
