Tiltable spring-biased chair

Abstract

A chair including a frame, a seat pivotally mounted on the frame, a spring construction effectively positioned between the seat and the frame, a first selectively actuatable latch positioned between the seat and the frame effective to maintain the seat latched in a less inclined position on the frame, a second selectively actuatable latch positioned between the seat and the frame effective to maintain the seat latched in a more inclined position on the frame against the bias of the spring construction, a seat back pivotally mounted relative to the seat, a leg rest pivotally mounted on the frame and movable between a retracted stowed position and extended positions, a cable secured to the leg rest for selectively releasing the leg rest from the retracted stowed position, a leg rest extension mounted on the leg rest, and a foot rest mounted on the leg rest extension.
