Abstract
An automotive vehicle headrest arrangement in which a headrest body is attached to a seat back so as to be controllably movable in a vertical direction and in a front-and-aft direction by driving mechanisms. The headrest arrangement comprises an outer stay and an inner stay which are vertically disposed in the seat back and vertically movable respectively by the driving mechanisms disposed in the seat back. The outer and inner stays are pivotally attached to a headrest body so that the headrest body is movable in a vertical direction and a front-and-aft direction under the vertical movement of the outer and inner stays. With this arrangement, since the headrest body is kept in a desired position without a fixing mechanism, the head rest arrangement is relatively simplified, thereby lowering a production cost. Additionally, since the driving mechanism of the headrest body is disposed in the seat back, the headrest body can be made relatively small-sized and light in weight, thereby realizing an improved safety upon reducing impact force from the headrest body to a passenger head without degrading passenger's comfortableness.
