Abstract: The present invention relates to a headrest locking device, and more particularly, to a headrest locking device including a case and a lock plate slidably accommodated in the case and inserted in an engaging groove of a stay rod. Here, a horizontal tension rib is located between the lock plate and the case. The horizontal tension rib applies an elastic force to the lock plate in a direction different from a sliding direction of the lock plate, and the lock plate has a panel shape formed by integrating a body inserted into the engaging groove with the horizontal tension rib. A gap between the lock plate and the case is eliminated and a restoring function is embodied at the same time, and manufacturing costs of the lock plate are reduced.

Abstract: This invention relates to a door latch system. The door latch system includes: a housing; a latch pivotally and rotatably installed in the housing; a main locking member slidingly installed in the housing for locking the latch; a sub-locking member slidingly installed in the housing and disposed in one side of the main locking member; a hook pivotally and movably installed in any one of the main locking member and the sub-locking member; a stopping threshold formed in the other one (wherein the hook is not installed) of the main locking member and the sub-locking member; and a locking plate slidingly installed in the housing for pivotally moving the hook, wherein the main locking member and the sub-locking member are sliding together when the hook is held by the stopping threshold by the sliding of the locking plate, and only the sub-locking member is sliding when the hook is separated from the stopping threshold by the sliding of the locking plate, so that even if the door lever is being pulled when the door is being locked, the unnecessary force is not transferred to the other components such as a latch, a main locking member, and the like.

Abstract: A headrest moving device, wherein a lever member, which is connected to the seat or the headrest in a pivoted state, presses the pawl, thereby releasing the engagement between the pawl and the ratchet. A consumer can release the locking at any position by operating a lever member externally protruded from the headrest after the consumer has moved the headrest. The method of releasing the locking can be easily recognized by the consumer, therefore the consumer can effectively and easily utilize the headrest moving device.
