    • The invention relates to a head rest (1) for a vehicle seat, said head rest comprising a carrier (5), at least one upper slide and one lower slide (11, 15) which are arranged on the carrier (5) in an articulated manner and can be pivoted about horizontal axes (7, 17), an impact element (13) which is arranged on the slides (11, 15) in an articulated manner and forms at least one four-bar linkage (19) with the slides (11, 15) and the carrier (5), and an energy accumulator (25). In the event of a collision, the energy accumulator (25) drives the four-bar linkage (19) in such a way that the impact element (13) moves forwards out of an initial position into a collision position which is blocked towards the rear by a collision blocking element. According to the invention, the upper slide (11) and the lower slide (15) assume a mutual position deviating from the parallelism.
    • 本发明涉及一种用于车辆座椅的头枕(1),所述头枕包括载体(5),至少一个上滑动件和一个下滑动件(11,15),所述上滑动件和所述下滑动件以 并且可绕水平轴线(7,17)枢转; - 以铰接方式布置在滑动件(11,15)上的冲击元件(13),并且形成至少一个四连杆机构(19),该四连杆机构 滑块(11,15)和载体(5)以及能量储存器(25)。 在发生碰撞时,蓄能器(25)以这样的方式驱动四连杆机构(19),即冲击元件(13)从初始位置向前移动到碰撞位置,该碰撞位置朝向后部 通过碰撞阻挡元件。 根据本发明,上滑动件(11)和下滑动件(15)呈现偏离平行度的相互位置。
