The hinge members are molded integrally with the seat, back and foot panels. Further, when the side panel of the wheelchair is formed, slots are formed therein for receipt of the hinge member. The same is true of the foot rest. The present invention also employs an improved adjusting mechanism for adjusting the pivotal relationship of the foot rest and an improved brake assembly.

Abstract: A completely collapsible chaise-cot deriving an unique compact folding characteristic from a folding transverse foot-base support structure. The folding support structure gives an increased compactable collapsibility to this invention over the folding chairs and cots of prior inventions. Earlier art, although achieving a modicum of collapsibility for cots, lawn chairs and the like, was devoid of full and compact collapsibility because no provisions had been made by the inventors to fold the common transverse base and upper frame supporting structures. The long felt need, therefore, for a folding, completely collapsible transverse foot-base support structure has been fulfilled by this invention and the art form has achieved a new level of utility as a result.
