Abstract
A mechanism for adjusting the angular position of the seat back relative to the chair seat on an office chair. A chair back support member attached to the seat back has a curved lower end. A chair seat support member attached to the chair seat has a curved rear end adapted to receive the curved lower end of the chair back support member. A first curved gear segment member having a plurality of closely spaced teeth is secured to the rear of the curved lower end of the chair back support member. A second curved gear segment member having a plurality of closely spaced teeth is retained within a spring loaded housing attached to the curved rear end of the chair seat support member. A lever which contacts the second curved gear segment member moves the teeth of the second curved segment member in or out of engagement with the teeth of the first curved segment member allowing the user to angularly adjust the chair back relative to the chair seat and to lock it into the selected angular position.
