Abstract
A quick release clamp assembly for retaining a hook type support bracket on a shaft. The clamp assembly can be used, for example, to secure a seat and backrest to the frame of a foldable wheelchair. The clamp assembly includes a clamp adapted to be attached to a frame member of the chair and a cam rotatably mounted to the clamp for operation between an open and a closed position for retaining the bracket on the frame member. In the preferred embodiment the cam also includes an over the center protrusion which tends to prevent the inadvertent opening of the cam and release of the bracket.
