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.

Abstract: Provided is a headrest moving device. When first and second gears, each of which has numerous teeth formed in widthwise and lengthwise directions, are engaged, the numerous widthwise teeth are engaged, and the numerous lengthwise teeth are engaged. Due to the teeth, it is possible to minutely adjust a position of a headrest and to withstand a high load. Even when some of the teeth are disengaged, the headrest moving device can be operated and provides excellent durability.
Abstract translation: 头枕移动装置。 当在宽度方向和长度方向上形成有多个齿的第一和第二齿轮接合时，多个宽度方向的齿接合，并且多个纵向齿啮合。 由于齿，可以精确地调节头枕的位置并承受高负荷。 即使当一些齿脱离时，也可以操作头枕移动装置，并提供优异的耐久性。

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.
