Abstract: A seat base includes abase, an arm and a release mechanism. The base includes a capture mechanism. The arm is coupled to the base and rotates through release, tension and unloaded positions. The arm frictionally engages a vehicle belt disposed between the arm and the base. The belt is disengaged from the arm when the arm is disposed in the release position. The capture mechanism is movable between an engaged position in which the arm is precluded from moving into the release position, and a disengaged position in which the arm is free to move into the release position. When the arm is disposed in the tension position and the capture mechanism is disposed in the engaged position, the capture mechanism is precluded from moving into the disengaged position.

Abstract: 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.
