ABSTRACT:
An improved chair back tilt apparatus for a wheelchair. The apparatus includes a seat and a back support pivotally coupled to the seat. A backrest is slidably coupled to the back support and coupled to the seat by a rigid L-shaped support. A linear motion actuator is secured between the seat and the back support to recline the seat. As the seat reclines, the L-shaped support pulls the backrest downward. The L-shaped support also forces the backrest upward as the seat is returned to its original position thereby substantially eliminating back shear associated with prior art back tilt systems.
