    • A vehicle seat includes a seat part displaceable at least in the seat longitudinal direction; a back rest that is held on the seat part; and an adjustable head restraint held on the back rest and having a head cushion. For automatically adapting the head restraint correctly in terms of safety to seat adjustments carried out by a seat user, a medium reservoir of variable volume, communicating with a filling and discharge device, is integrated in the head cushion so that the cushion front face is shifted forwards during an increase in volume and is drawn back again as a result of a reduction in volume. The filling quantity introduced into the medium reservoir or drawn off from the medium reservoir is controlled depending on the seat setting by means of a control unit. The medium reservoir also may include a pressure limiter that allows a controlled outflow of the reservoir when a predetermined pressure value, caused by the impact of the head, is reached.
    • 车辆座椅包括可以至少在座椅纵向方向上移动的座椅部件; 搁置在座椅部分上的靠背; 和一个保持在靠背上并具有头垫的可调头枕。 为了在座椅使用者进行的座椅调节方面自动适应头枕正确的调节,与头部衬垫连通的可变容积的介质储存器被集成在头垫中,使得衬垫前面移动 在体积增加期间向前推进,并且由于体积的减小而再次被拉回。 根据通过控制单元的座椅设定来控制引入到介质容器中或从介质储存器中取出的填充量。 介质储存器还可以包括压力限制器,当达到由头部的冲击引起的预定压力值时,该压力限制器允许储存器的受控流出。
