Abstract
A wheelchair back system is disclosed having a bolster with an improved mounting means. The bolster has a rear surface which is positioned on a lateral portion of the wheelchair back. A strap attached to the front surface of the bolster extends to and engages the front surface of the back, toward the center of the back. The strap provides the bolster with enhanced resistance to lateral forces which may be applied to the bolster during the use of the wheelchair.
