The present invention discloses an overload protection mechanism for a cable actuated feature on an office chair. The overload protection device allows a person seated in the chair to move a handle to actuate the particular feature of the chair, for example, a reclining backrest, even when the seated person's weight on the backrest prevents the backrest locking mechanism from engaging or disengaging. The movement of the handle causes the cable to move even when the locking mechanism connected to the opposite end of the cable is unable to engage or disengage. The mechanism stores the motion of the cable in a spring device connected to the movement actuators by a rack and pinion gear system. When the binding is released from the actuators, the mechanism moves as originally intended, motivated by the force of the decompressing springs.
