ABSTRACT:
A reclining elevator chair having a tiltable back, an extendible leg rest, and means for raising the seat and simultaneously tilting it forwardly to assist arthritic or other partially disabled persons in leaving the chair. A power-driven ram tilts the back and extends and retracts the leg rest in one mode of operation. In a second mode of operation, the same ram raises the seat and tilts it forwardly. The first mode of operation occurs when the ram is retracted below a predetermined length and the second mode of operation occurs when the ram is extended beyond the predetermined length. When the ram is equal to the predetermined length, a portion of the mechanism which tilts the back and extends and retracts the leg rest abuts against a portion of the seat frame and transfers the force of the ram from the back and leg rest to the seat.
