ABSTRACT:
An adjustable chair includes a base, a seat, a back and a chair control for pivotally connecting the back to the base for movement between an upright position and an inclined position. The seat is pivoted to the base at a front end. The seat is also connected to the base by a plurality of locking plates. A spring clamp normally holds the plates in a locked position. The clamp permits pivotal adjustment of the seat with respect to the base. A cable actuated back stop or lock includes a lever pivoted to the back. When in the operative position, the lever contacts the locking plates connected to the seat to limit or prevent tilting of the back with respect to the seat.
