ABSTRACT:
A tilting device for a wheelchair and occupant comprises an outer frame defining a base and upstanding triangular supports at an inner frame pivotally mounted on the outer frame at the top of the triangular supports. The inner frame comprises a back rest and platform with a rearwardly extending section to receive the wheels of the wheelchair and parallel guides spaced by the width of the wheelchair to prevent twisting. The pivot axis passes through the occupant and the inner frame can be pivoted relative to the outer frame by operation of a handle which rotates a screw, axial movement of which acts to pivot the inner frame by actuation of suitable levers.
