    • A head rest of a vehicle seat may include a head support portion for supporting a head of a passenger, and a drive unit for moving the head support portion. The drive unit has a moving mechanism that is arranged and constructed to move the head support portion vertically and back and forth relative to the vehicle seat, a head detecting device provided to the head support portion so as to detect a clearance between the passenger head and the head support portion and to generate a control signal representative of the detected clearance, and a controller that can control the moving mechanism. The controller controls the moving mechanism so as to move the head support portion to a first proximity position in which the head detecting device may have a predetermined sensitivity relative to passenger head if the head support portion does not reach the first proximity position. The controller further controls the moving mechanism based on the control signal from the head detecting device so as to move the head support portion to a second proximity position which corresponds to an optimal proximity position relative to the passenger head.
    • 车辆座椅的头枕可以包括用于支撑乘客的头部的头部支撑部分和用于移动头部支撑部分的驱动单元。 驱动单元具有移动机构,该移动机构被布置和构造成使头部支撑部分相对于车辆座椅垂直和前后移动,头部检测装置设置在头部支撑部分上,以便检测乘客头部和 头部支撑部分并且产生表示检测到的间隙的控制信号,以及可以控制移动机构的控制器。 控制器控制移动机构,以便如果头部支撑部分没有到达第一接近位置,则头部支撑部分移动到第一接近位置,在该第一接近位置,头部检测装置可相对于乘客头具有预定的灵敏度。 控制器基于来自头部检测装置的控制信号进一步控制移动机构,以便将头部支撑部分移动到相对于乘客头部的最佳接近位置对应的第二接近位置。

    • A headrest height adjusting apparatus includes: a basal member attached to a seatback and supporting a driving member; a movable member linked to a headrest and lifted up and down relative to the basal member; a transmitting member transmitting a driving force of the driving member to the movable member and lifting up and down the headrest linked to the movable member. The transmitting member having a frangible portion that leads a collapse of the transmitting member against an impact applied in a vertical direction between the driving member and the movable member and absorbs energy of the impact.
    • 头枕高度调节装置包括:附接到座椅靠背并支撑驱动构件的基座构件; 连接到头枕并相对于基部构件上下升降的可动构件; 传递构件,其将所述驱动构件的驱动力传递到所述可动构件,并且使与所述可动构件连接的所述头枕上下升降。 所述传递构件具有易碎部分,其导致所述传递构件的塌陷抵抗在所述驱动构件和所述可动构件之间沿垂直方向施加的冲击并吸收所述冲击的能量。

    • An aircraft ejection seat includes a frame and a headrest. The vertical position of the seat is adjusted by a pair of motor driven lead screws that cooperate with threaded barrel nuts attached to the seat frame. The upper end of one of these motor driven lead screws drives a slip coupling driving a splined shaft. The splined shaft then drives a gearbox mounted to the seat frame. The gearbox in turn drives an upper lead screw, which acts on an upper barrel nut to move the headrest up and down relative to the seat frame. The upper lead screw is driven in the opposite direction from the lower lead screws. Consequently, as the seat moves up to accommodate a shorter pilot, the headrest moves down to accommodate the shorter torso of the shorter pilot.
    • 飞机弹出座椅包括框架和头枕。 座椅的垂直位置通过一对电机驱动的导螺杆来调节,该导螺杆与安装在座椅框架上的螺纹筒螺母配合。 这些电机驱动的丝杠中的一个的上端驱动滑动联接器驱动花键轴。 花键轴然后驱动安装到座椅框架的变速箱。 齿轮箱又驱动上导螺杆,其作用在上筒螺母上,以相对于座椅框架上下移动头枕。 上导螺杆与下导螺杆沿相反方向驱动。 因此,当座椅向上移动以容纳更短的飞行员时,头枕向下移动以适应较短飞行员的较短的躯干。
