ABSTRACT:
An adjustable chair arm is used with a chair that has a base, a seat supported by the base, and a back connected with the base. The arm is an elongated member that is connected with the base and has two opposing ends. An arm adjustment device is interposed between the arm and the base and has a drive rod, a frame, a torque member, a brake, and a brake actuator. The frame holds the drive rod in rotating engagement. The torque member is connected between the frame and the drive rod and applies a torsional force to the drive rod. The brake has a locked mode and a released mode and holds the drive rod in preselected rotational positions, relative to the frame. The brake actuator manipulates the brake between the locked and released modes.
