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.
本发明涉及一种头枕锁定装置,更具体地,涉及一种包括壳体和可滑动地容纳在壳体中并插入到撑杆的接合凹槽中的锁板的头枕锁定装置。这里,水平张紧肋位于锁板和壳体之间。所水平张紧肋沿与所述锁板的滑动方向不同的方向对所述锁板施加弹力,并且锁板具有通过将插入所述接合凹槽中的主体与所述水平张紧肋集成一体而形成的面板形状。消除了锁板与壳体之间的间隙,同时实现了恢复功能,降低了锁板的制造成本。
