An invalid chair for handicapped persons designed to facilitate sitting down and rising in which the seat of the chair and the footrest are a single frame and both are pivotally mounted to a front cross member so that the seat will be moved pivotally up and forward as the footrest moves down and back to thus assist the person in rising from the chair and vice versa the seat will move pivotally down and back as the footrest moves up and forward and in addition a plurality of resilient springs or stretchable straps will resist the downward movement of the seat to assist the invalid in a seating operation and resist the progressive upward pivotal movement of the chair's footrest. The chair when empty will be biased to hold the footrest down and seat up ready to accept a person on the footrest and when the person steps upon the footrest and leans back in a sitting position, the weight of the chair occupant will automatically produce a pivotal movement of the footrest and seat and be partially retarded in its pivotal movement by the resilient stretchable straps.
An invalid chair for holding a patient in a sitting position comprising a single rigidly connected chair base frame formed with four upright supports joined in a square relationship by side, front and back rails and provided with a seat support rail, two side arm support rails connected to said four upright supports as a part of said single rigid frame, a cross bar extending between said side rails adjacent said seat support rail and a back rest frame pivotally connected to said crossbar, a single rigidly formed footrest and seat supporting frame pivotally mounted to said front rail, and resilient straps connected at one end to the footrest portion of said footrest and seat supporting frame and connected at the other end to said cross bar, whereby said straps resist the backward and downward movement of said seat portion of said footrest and seat supporting frame.
