Abstract
A wheelchair includes a chassis having a pair of side frame assemblies that are rigidly connected to each other by a seat pan. Mounted on each side frame assembly is an interchangeable axle receiving platform for orienting drive wheels at a desired camber angle. One end of a seat member is pivotally attached to a foot member for adjustment of the seating angle. By moving an opposite end of the seat member along a curved portion of a bottom member of each side frame assembly, the seat angle is changed. A one piece caster assembly is disposed forward of the drivewheels on the chassis. Through the one-piece caster assembly, each caster can be simultaneously adjusted to a particular location along the frame.
