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 in- jury) or a quadriplegic may require a higher backrest with an increased level of recline (FIGURE 9).

Recliner Back Upholstery (FIGURE 10)

2.Remove existing back upholstery from back canes.

3.Install new back upholstery onto the back canes.

4.Install the ten (10) or twelve (12) phillips screws and washers (depending on back height) that secure the back upholstery to the recliner back canes.

ADJUSTING THE BACK HEIGHT

FIGURE 9

Adjustable Height Backs (FIGURE 11)

The effect of back support and the angle of the backrest are interconnected. Changes to one often requires change to the other if optimal support and balance are to be achieved. Use of a wheelchair with adjustable ten- sion upholstery can significantly increase function, pos- tural condition, balance and comfort.

1.Remove the two (2) hex bolts and locknuts that se- cure the two (2) back canes to the wheelchair frame.

2.Reposition the back canes to one (1) of five (5) height adjustment positions. Refer to the SPECIFICATION PAGE of this manual for the height range of the indi- vidual back canes.
