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.

Abstract: Provided is a headrest folding apparatus. An oblique face is formed on a support for supporting a headrest. When the headrest is in an upright position, the oblique face comes into contact with a first member. The headrest folding apparatus prevents a loose gap from occurring in an upright state, simplifies components to be made compact, and allows a seat to be easily assembled and a manufacturing cost to be cut down.

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.
