A seating posture is stabilized for the shoulders of a passenger seated on a vehicle seat. A vehicle seat is provided with a seat back configured to support the seated person from the rear. A shoulder support portion of the seat back configured to support a corresponding one of the shoulders of the seated passenger includes an air cell configured to expand when air is supplied. When the air cell expands, one end portion of the shoulder support portion on the outside in the width direction of the vehicle seat moves more forward than the other end portion of the shoulder support portion on the inside in the width direction.

The invention relates to a vehicle seat having a seat part and a backrest part, which comprises a lower backrest part and an upper backrest part arranged adjacent thereto in the vertical direction of the vehicle seat, a displacement device being arranged with a first section, which is fixedly connected to the lower backrest part, and with a second section, which is fixedly connected to the upper backrest part, the second section being completely displaceable together with the upper backrest part relative to the lower backrest part by means of a displacement movement directed at least in part in the width direction of the vehicle seat, the first section being arranged completely below the upper backrest part in the vertical direction and forming a guideway for the displacement movement of the second section.

A seat assembly includes a seat bottom, a seat back, and a head restraint. The seat back is connected to the seat bottom and is configured to pivot relative to the seat bottom between an unfolded position and a folded position. The head restraint is connected to the seat back and is configured to pivot relative to the seat back between an unfolded position and a folded position. The head restraint is configured to automatically pivot from its folded position to its unfolded position when the seat back pivots from its folded position to its unfolded position.

A backrest may have a seat back structure and a carrier module for a headrest. The carrier module may have at least one carrier element arranged on an upper portion of the seat back structure and fixedly connected to the seat back structure. The carrier module may also have at least one supporting element adapted to support the carrier element. The at least one carrier element may have a receiving space configured to receive the headrest and a fixing structure projected towards into the receiving space and adapted to detachably fasten the supporting element to the carrier element. The backrest may be used with a seat.

A seat back pad 70 has a groove 73 for tucking a skin material therein, formed at borders between a central portion 71 and side portions 72. A hole (slot hole 74) is formed in a bottom of the groove 73 along the groove 73. A tuck-in wire 76 for tucking the skin material in includes a plurality of tuck-in portions 76A provided along the groove 73, and a connecting portion (detour portion 76B) detouring around the hole and connecting the tuck-in portions 76A. With this configuration, when an upper body of an occupant P subsides into a seat back S2 in a rear-end collision of a vehicle, the central portion 71, defined by the groove 73 as a border, is easily and sufficiently moved rearward relative to the left and right side portions 72. Furthermore, the tuck-in wire 76 is not exposed through the hole, and thus adhesion between the seat back pad 70 and the tuck-in wire 76 can be improved.

A lining element for a backrest of a vehicle seat, in particular for the rear face of the back seat is provided. A number of soft lining parts, which are arranged on the front face, and two or more solid lining parts, which are arranged on the rear face and are connected to the soft lining parts, are provided. The degree of deformability of the lining elements towards the rear is preferably greater than the degree of deformability towards the front.

A vehicle seat having a vehicle seat base comprising a generally concave seat pan (4) and side plates (16) fixed to the seat pan for mounting the seat pan to the vehicle wherein the seat pan has, all relative to the direction of movement of the vehicle, a front face, a rear face, two lateral side faces and a bottom face, and wherein the side plates extend from the front towards the rear of the seat pan and are bonded to the lateral side faces along at least part of the length of each of the side plates. This produces a lightweight yet rigid seat base which enables a low block height.

A passenger seat having improved backrest comfort features. The passenger seat has a backrest with a movable portion. In one example, the movable portion is defined by an upper backrest portion that can slide up and away from a lower backrest portion to provide a gap between the two portions. The gap 5 may provide an arm or elbow rest for a seat occupant. The movability of the backrest can also provide enhanced comfort for the seat occupant by allowing adjustability of the head rest portion. In other examples, the movable portion comprises the entire backrest of the seat. When in a raised position, the backrest may also provide enhanced privacy to the seat occupant.

A motor vehicle including at least one individual seat is provided. The individual seat includes a seat part and a backrest. The seat part has a seat-part main shell and seat-part side shells arranged thereon on respective sides. The backrest has a backrest main shell and backrest side shells arranged thereon on respective sides. A rail system is provided, which moves the respective seat-part side shell and/or the respective backrest side shell in a desired or specified position by way of actuators.

A seat assembly includes a first seatback and a second seatback. The first seatback may include a first seatback upper portion and a first seatback lower portion. The second seatback may include a second seatback upper portion and a second seatback lower portion. The seat assembly may further include an intermediate back section including an intermediate upper portion and an intermediate lower portion. The first seatback lower portion and the second seatback lower portion may be arranged on opposite sides of the intermediate lower portion. The seat assembly may also include a carrier frame to which the first seatback upper portion, the second seatback upper portion, and the intermediate upper portion may be connected. At least one of the first seatback upper portion, the second seatback lower portion, and the intermediate upper portion may be adjustably connected to the carrier frame.
