In order to suppress a claustrophobic feeling that a person sitting on a rear seat receives due to a front seat, and to make the front seat easy to use as an ottoman by the person, a movement adjustment system is used for a passenger seat and a rear seat, and includes a slide rail for moving the rear seat in the front to back direction, and a control part for changing the movement region of the rear seat by the slide rail. The passenger seat has a seat cushion, and a seat back mounted to be changeable between an upright state and a lowered state with respect to the seat cushion. The control part changes the movement region so that the passenger seat and the rear seat can come closer when the seat back of the passenger seat is in the lowered state than in the upright state.

A vehicle seat includes a back frame connected to a base member so as to be able to rotate around a first rotation shaft; a rotation locking mechanism; a cushion frame connected to the back frame so as to be able to rotate around a second rotation shaft, and in which a long hole is formed; a link member connected to the base member so as to be able to rotate around a third rotation shaft; a fourth rotation shaft fixed to the link member and inserted in the long hole so as to be able to move relatively and so as to be able to rotate; and movement restricting portion provided between the fourth rotation shaft and an inner surface of the long hole, and that restricts movement of the fourth rotation shaft from one end portion of the long hole toward another end portion side.

A seat assembly of a vehicle may include a support having a lower end portion connected to a floor of the vehicle; a seat frame having a connection portion provided above the support and having an entire slope which is changed by a curvature of the connection portion when the connection portion is slid, the connection portion being formed in a curved line or a curved surface; and a seat mounted on the seat frame and configured for implementing reclining by having a slope which is changed together with the seat frame when the seat frame is slid on the support.

A seat module for a motor vehicle that includes a carrier element having at least one seat row upon which at least two seats are secured. Each seat row has walls defining an opening which is accessible from outside of the motor vehicle and which extends laterally as a hollow space into the carrier element. The walls are fixed at least partially peripherally to facilitate raising of the seat module via introduction of a lifting element from outside of the motor vehicle into the hollow space for installation of the seat module into the motor vehicle or removal of the seat module from the motor vehicle.

A vehicle seat comprises a seating portion and a back rest the angle of inclination is adjustable in relation to the seating portion, where at least the back rest is of modular design made of a plurality of upholstered elements, the upholstered elements each comprising a preformed foam part surrounded, at least in part, by a cushion cover, the upholstered elements made in this manner are put together via fasteners in modular fashion to form the back rest adjustable in inclination.

A seating arrangement for a vehicle is shown to include a plurality of seats, including at least two front seats, at least two rear seats, and a rear jump seat positioned intermediate the two rear seats. The jump seat comprises a seat back which is positioned rearwardly of the rear seats, and the rear seats are movable laterally between a first position where the rear seats are proximate to each other and generally covering the seat back of the jump seat, and a second position where the rear seats are spaced apart from each other and the seat back of the jump seat is exposed. The arrangement may also include rear seats which are rotatable relative to the seat backs to provide a storage surface.

A drive bush configured to circumferentially rotate and drive a pair of wedge members in an eccentric space includes a cylindrical portion rotatably supported inside a boss portion of an internal tooth constituting member, a flange portion integrally formed at a first end portion in the axial direction of the cylindrical portion so as to face one side surface side of the wedge members, and a pushing portion integrally provided on the outer peripheral side of the flange portion, and configured to release a wedge effect by circumferentially pushing the wedge members. The inner surface of the cylindrical portion is integrally formed with a wall portion, and the wall portion is formed with, in the middle thereof, a female spline teeth meshing with the output shaft of a motor. The cylindrical portion, the wall portion including the female spline teeth and the flange portion have substantially the same thickness.
