Abstract
Abstract A tiltable support for a wheelchair includes a main base for supporting a wheelchair, an angular base section for supporting the wheelchair in a rearwardly tilted position, and a back rest for supporting the back of the wheelchair while in the tilting position. In one embodiment, the support may be moved manually between one position in which the main base rests upon an underlying horizontal support, for disposing a wheelchair patient in an upright sitting position, and a second position in which the angular base rests upon the horizontal underlying support for disposing the wheelchair patient in a rearwardly reclining position. In a second embodiment, power driven mechanism is integrated with the support for moving it between the upright and reclining positions of the wheelchair patient.
