ABSTRACT:
A wheelchair frame assembly is provided with a foot rest mounting assembly and a caster mounting assembly that are mounted on side frame assemblies. The foot rest mounting assembly includes two foot plate mounting bars connected to respective side frame assemblies for mounting a foot plate. The foot plate mounting bars are positioned such that they angle inwardly towards one another to provide support for the lower portions of the legs and to allow easier movement into tight spaces. A foot plate is mounted to the end of each foot plate mounting bar in a manner that compensates for the obliquely downwardly extending and inwardly tapered nature of the foot plate mounting bar. The caster mounting assembly includes a fork that is provided with a plurality of holes for mounting casters of progressively greater diameter and for providing greater trail for progressively greater diameter casters. The wheelchair frame is also constructed to permit adjustment of the seat pan angle without changing the caster alignment and without altering the position of the drive wheel axles. The wheelchair can be constructed by attaching one of several different rear frame portions to a common side frame assembly in order to vary the cost and the performance characteristics of the wheelchair.
