    • The invention relates to a headrest (10) for a vehicle seat, in particular for a backrest for a motor vehicle seat, said headrest essentially comprising a headrest frame or headrest casing (14) and a foam base body (356) that surrounds the headrest frame or casing (14). In the event of a rear impact on the motor vehicle, the headrest remains fixed in relation to the backrest (conventional headrest) or at least part of the headrest is immediately displaced towards the vehicle occupant (active headrest). According to the invention, the head of a vehicle occupant can be brought into contact with the headrest (10) at least at two different heights (k1z, k2z), (two-point contact), to reduce or neutralize a torque (My) about a y-axis (y-y) in the vicinity of the vertebral column and to prevent accident-related injuries to the seat occupant, in particular to prevent cervical spine syndrome or a whiplash injury in the event of a front and/or rear impact. A head centre of gravity (HCG) is also configured between the two heights (k1z, k2z) of the headrest (10).
    • 本发明涉及一种用于车辆座椅的头枕(10),特别是用于机动车辆座椅的靠背,所述头枕基本上包括头枕框架或头枕壳体(14)和围绕头枕的泡沫体基体(356) 框架或套管(14)。 在机动车辆的后方碰撞的情况下,头枕相对于靠背(常规头枕)保持固定,或至少部分头枕立即向车辆乘员(主动头枕)移动。 根据本发明,车辆乘员的头部可以至少在两个不同的高度(k1z,k2z)(两点接触)处与头枕(10)接触以减少或中和扭矩(My) 关于脊柱附近的y轴(yy),并且防止座椅乘客发生事故相关的伤害,特别是在前后冲击的情况下防止颈椎综合征或鞭打伤害。 头枕重心(HCG)也配置在头枕(10)的两个高度(k1z,k2z)之间。

    • The invention relates to a headrest arrangement for a backrest section (10) of a motor vehicle seat with a headrest, which receives the headrest bars and is supported in the guides on the side of the backrest, wherein the guides in the backrest can be moved within limits from a normal operating position (68) to a crash-active operating position (70).It is provided that for displacing the headrest from the normal operating position (68) relative to the backrest section, an activation unit (11) is provided, which extends essentially along, and at the same height as, a shoulder section of the seated person, wherein an activation shield (38) of the activation unit is displaced rearward in the event of a rear crash—due to the mass inertia of the seated person, whereafter the rearward displacement of the activation shield (38) is transferred via an eccentric shaft (24), causing the guides (18) of a headrest adjustment unit (12) to perform a direct rotational and translational motion so as to attain the crash-active operating position (70).
