    • A vehicle seat includes a bracket for mounting to a vehicle body. A seat back frame is pivotally connected to the bracket for movement between an upright position and a collapsed position. A head restraint is mounted to the seat back frame to translate relative to the frame. A transmission is connected to the bracket, the frame and the head restraint to provide a geared engagement between the head restraint and the bracket such that translation of the head restraint relative to the seat back frame is a direct relationship of a pivotal position of the seat back frame relative to the bracket in order to extend the head restraint at the upright position and to retract the head restraint in the collapsed position.
    • 车辆座椅包括用于安装到车体的支架。 座椅靠背框架枢转地连接到支架,用于在直立位置和折叠位置之间运动。 头枕被安装到座椅靠背框架上以相对于框架平移。 传动装置连接到支架,框架和头枕以提供头枕与支架之间的齿轮啮合,使得头枕相对于座椅靠背框架的平移是座椅的枢转位置的直接关系 相对于支架的后框架,以便将头枕延伸在直立位置并使头枕在收缩位置收回。

A head restraint is mounted to the frame. A shaft cooperates with the stop and the frame and includes a series of notches and the stop includes at least one projection that engages the notches in a locked rotary position of the shaft. The projection is disengaged from the notches in a released rotary position of the shaft. The shaft has a cam and an actuator has a follower arrangement for releasing the shaft to slide the head restraint frame along the rod. A head restraint assembly is also provided wherein the series of notches and the projection cooperate such that height adjustment in an upward direction only is permitted without actuation of the actuator.
    • 车辆座椅头部约束组件设置有安装到车辆座椅靠背的杆上的止动件。 框架安装到杆上以沿着其滑动。 头枕安装在框架上。 轴与止动件和框架配合并且包括一系列凹口,并且止动件包括至少一个突出部,该突起与轴的锁定旋转位置中的凹口接合。 突起在轴的释放旋转位置与凹口脱离。 轴具有凸轮,并且致动器具有随动装置,用于释放轴以沿着杆滑动头枕框架。 还提供了一种头枕组件,其中所述一系列凹口和所述突起配合,使得仅在允许所述致动器致动的情况下允许在向上方向上的高度调节。
