Title: Convertible wheelchair and a method for converting a wheelchair chassis

Abstract: A wheelchair comprises a frame and a chassis. The frame has two side frame members. The side frame members include upper frame members. The upper frame members have first and second mounting positions upon which the chassis may be mounted. The chassis has two mounting brackets. The mounting brackets are selectively attachable to respective upper frame members at the first and second mounting positions. The mounting brackets have lower ends that are structured and configured to rigidly support a rear wheel assembly when the mounting brackets are attached to the upper frame member at the first mounting position to provide a fixed chassis. When the mounting brackets are attached at the second mounting position, the lower end of the mounting brackets pivotally support a swing-arm assembly and suspension member to provide a suspension chassis. The same mounting brackets may be provided to construct each chassis or different mounting brackets may be provided to construct each chassis. The invention also includes a method for converting the chassis of a wheelchair from a rigid chassis to a suspension chassis, and vice versa.
