A size-adjustable wheelchair seat comprises a first size-adjustable frame member, a second size-adjustable frame member and a cross frame member. The first frame member extends generally in a longitudinal direction. The first frame member includes a first penetrating frame element and a first receiving frame element. An end of the first penetrating frame element is telescoped within an end of the first receiving frame element. The second frame member is spaced laterally from and extends generally parallel to the first frame member. The second frame member includes a second penetrating frame element and a second receiving frame element. An end of the second penetrating frame element is telescoped within an end of the second receiving frame element. The cross frame element extends between the first frame member and the second frame member. The cross frame element comprises a first generally tubular sleeve portion, a second generally tubular sleeve portion and an elongate body extending between the first and second sleeve portions. The first sleeve portion is adapted to surround the first frame member. The second sleeve portion is adapted to surround the second frame member. The first and second sleeve portions are slidable longitudinally along the first and second frame members, respectively.

Adjustable seat for wheelchairs

A size-adjustable load supporting device comprising a load supporting top panel and a size-adjustable support frame. The support frame is adjustable laterally and longitudinally to fit a variety of wheelchairs and to accommodate different sized patients. The load supporting top panel is removably attached to the size-adjustable frame with VELCRO.RTM.. The support frame is comprised of four T-shaped components which are nestingly interfit with one another and slidable relative to one another to form a generally square support frame. With the top panel removed, the length and width of the support frame can be quickly adjusted by sliding the T-shaped components relative to one another to vary the amount of nesting. Once the support frame is adjusted to the desired size, the top panel is reattached, thereby securing the support frame. Four J-shaped brackets are provided, two on each side, to allow the device to be easily mounted on a standard wheelchair. The brackets are vertically adjustable and rotatable relative to the support frame to permit the size-adjustable load supporting device to be mounted at a range of heights and at a variety of angles relative to the wheelchair frame.
