8.3Adjustable Tension Back Upholstery

￿ WARNING

ALWAYS perform these procedures in the presence of an assistant. The position of the footrest, camber tube, seat angle, back angle, the tautness of the back upholstery as well as the user's condition are directly related to the wheelchairs stability. Any change to one or any combination of the five may cause the wheelchair to decrease in stability. Use EXTREME caution when using a new seating position. The addition of anti-tippers may be required.

The Back Upholstery Cover

The back upholstery cover is designed for three reasons:

The first is as a modesty cover.

The second is to keep the cushion from sliding out of the back of the wheelchair.

The third is a sacral support depending upon how far or tight the flap is pulled under the seat cushion.

The adjuster fastening straps can be adjusted at various levels of tension to accommodate individual end-users.
