ABSTRACT:
An adjustable chair includes a base, a back support, a control on the base, a seat positioned on the control and an actuator housing supported on the base. The control mounts the back for tilting movement between a fully upright position and reclined position. A seat is pivoted to the base at a front end. The seat is also connected to the base by a plurality of locking plates. The chair includes a back stop subassembly, a back or seat tension subassembly, a seat tilt subassembly and a seat depth subassembly. The actuator housing is an elongated, tubular member having concentrically mounted controls or actuators at each end. At one end of the actuator, a rotatable actuator controls back tilt tension and a concentrically mounted, push button actuator controls the back tilt or stop position. At the opposite end of the actuator housing, a rotatable actuator controls seat tilt position and a concentrically mounted pivotal lever or button controls positioning of the seat to adjust the depth through the depth subassembly.
