Abstract: A retractable seat of laterally folding type wherein a seat portion thereof is caused by a motor to displace in a direction laterally of a vehicle. The seat portion is pivotally connected, via connecting arm and support elements, with a support base element provided in the vehicle body. The motor and drive transmission elements are securely provided in the seat portion, such that the motor is operatively connected via the drive transmission element with a drive shaft fixed to one end of the connecting arm. Operation of the motor causes displacement of the seat portion in the direction laterally of the vehicle body toward one of a use position on a floor and a non-use storage position where the seat portion extends upright adjacent to a lateral side of the vehicle. The motor is controlled by electric and electronic elements and systems.

Abstract: A powered slide rail device including an electrode element extending along the lower rail thereof and a contact brush element provided in the upper runner rail element thereof which is slidably engaged with the lower rail. The electrode element is so arranged as to provide a sloped surface. The contact brush element, with which an output connector is electrically connected, projects from the upper runner rail element and contacts such sloped surface of electrode element. A biasing element may be provided to retain the contact brush element in contact with the sloped surface of electrode element.

Abstract: Vehicle seat of retractable type having a rotary support link mechanism, which is displaceable between upper use position and lower storage position. The rotary support link mechanism comprises a forward link element and a backward link element smaller in length than the forward link element, wherein the forward link element has upper and lower pivotal support points between the seat and a vehicle floor, while the backward link element has upper and lower pivotal support points between the seat and vehicle floor. The lower pivotal support point of the backward link element is disposed backwardly of and above the lower pivotal support point of the forward link element, and the backward link element is inclined more backwardly than the forward link element. With this arrangement, the seat can be displaced by operation of motor between the upper use position and lower storage position in a manner analogous to a manual operation.

Abstract: An armrest of the type rotatable laterally of a seat back of a seat, wherein the armrest is rotatable between an upright non-use position and a horizontal use position, by virtue of a stopper plate having a first limit projection defining the non-use position and a second limit projection defining the use position, the stopper plate being fixed on a support rod on which is also rotatably mounted the armrest in such a manner that the stopper plate is disposed between the lateral wall of the seat back and the armrest body. Such stopper plate is engageable with a pin provided within the armrest.

Abstract: A power seat for an automobile wherein the seat cushion is adjustable in height or in a fore-and-aft direction by means of an electric motor. In such power seat, an upstanding bracket is provided on a slide rail adapted to permit fore-and-aft sliding movement of the seat cushion, and the electric motor is disposed at the lateral surface of the bracket. Hence, there is no need to dispose the motor beneath the seat cushion, and the seating point is lowered more, giving a wide space in the cabin of the automobile.

Abstract: A height adjusting device for an automotive seat comprising a forward seat height adjusting mechanism adapted for height adjustment of the forward part of a seat cushion, a rearward seat height adjusting mechanism adapted for height adjustment of the rearward part of the seat cushion, a control mechanism which is operatively connected with those two height adjusting mechanism, and a pair of first and second sprocket wheels with an endless chain wound thereabout are arranged between the rearward height adjusting mechanism and control mechanism. Thus, a rattling or wobbling is avoided in the rearward height adjusting mechanism.

Abstract: A head-rest for a vehicle seat is disclosed which is mounted to a seat back frame in such a manner as to be free to rotate longitudinally of the vehicle. Support members for supporting the head-rest and a lock plate formed with a large number of locking grooves are fixed to a shaft of rotation provided between two brackets. The lock plate is rotated with the longitudinal movement of the head-rest and a stopper provided in the bracket is engaged into one of the locking grooves in the lock plate so that the head-rest is locked in its desired position.
