ABSTRACT:
A powered headrest for an automotive seat, which includes, within a seat back of the seat, a slider member engageable with a stay of the headrest, the slider member being moved vertically by operation of a motor, a rotatable guide rod, and a lock member to be engaged biasingly with a recessed portion of the stay. An operation knob and associated connecting elements are provided in the headrest, with such an arrangement that to simply operate or press the knob will cause rotational motion of the guide rod, and the lock member will only be interlocked with that rotational motion of guide rod, so as to place the headrest stay in an unlocked state with respect to the slider.
