A locking apparatus for a seat assembly for a vehicle is provides and includes a latching component attached to one of a stationary part or a movable part of a seat assembly, a receiving component disposed on the other of the stationary part or the movable part of a seat assembly, wherein the latching component engages the receiving component, and an activation component that activates the latching component. Upon activation of the locking device, the latching component engages the receiving component thereby locking the movable part to the stationary part in a collapsed state thereby reducing vibrational noise caused by the movable part during operation of the vehicle.
