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.

The locking device includes a lock spring having a nipping portion with which a projecting pin is nipped so that the partition plate is fixed to the luggage floor. The nipping portion is enlarged to disengage from the projecting pin when an elongate pushing member is rotated upon rotation of an operating lever.

Abstract: A power seat drive mechanism for an automobile has a motor which drives a worm which in turn drives a worm wheel at a given speed. The worm wheel is connected to a threaded shaft which it drives to rotate. Rotation of the threaded shaft forces it through a nut which is fixed to the body of the vehicle. This drives the threaded shaft which is connected to the sliding frame of the seat longitudinally with respect to the vehicle. In order to prevent force exerted on the seat in the direction of its travel, from causing the threaded shaft to rotate faster than it is being driven and thus overrun the worm gear, a resilient governor member is included which provides a limited braking effect and tends to resist the rotation of the shaft. With this configuration, backlash in the drive mechanism is eliminated.

Abstract: A head rest for the seat of an automotive vehicle is attached to a stay by means of a bolt which tightens a clamping clip onto the stay. The same bolt functions to hold the clip in place within the internal structure of the head rest. The engaging pressure of the clip can be adjusted by the bolt, and therefore, the precision with which the parts are formed does not need to be high allowing the head rest to be made inexpensively. By providing the clip in the interior of the head rest as opposed to an outside surface, it is possible to prevent injury to the vehicle occupants which might otherwise be caused by impacts on the clip or the bolt during an accident.
