An apparatus for adjusting the back support provided by a backrest of a wheelchair formed with sling construction. The backrest has flexible upholstery and two generally vertical support posts for anchoring the sides of the upholstery so that the upholstery extends between the support posts. When the occupant leans against the upholstery, the apparatus includes at least one cushion which contacts a portion of the upholstery behind the occupant to provide a desired configuration and distribution of support to the back of the occupant. The apparatus also has straps extending between the cushion and the support posts. The straps may be adjusted to position the cushion at a desired location along the rear face of the upholstery and adjust the degree of support provided to the occupant by the apparatus. |
