A seat for a motor vehicle includes a basic shell and a seat surface. The seat surface includes a vacuum layer and an air cushion layer; and the air cushion layer is arranged between the vacuum layer and the basic shell. Also disclosed is a motor vehicle having such a seat.

A seat accessory for an automobile vehicle includes a seat accessory configuration oriented to be releasably deposited onto a seat base and a seat back of an automobile vehicle seat when the seat back is positioned in a seat back fully reclined and horizontal position. The seat accessory includes a seat base contact portion defining a triangular-shape positioned onto the seat base. A seat back contact portion defining a triangular-shape is positioned onto the seat back. A connecting member directly connects the seat base contact portion to the seat back contact portion.

A fluid bladder valve for a pneumatic vehicle seat adjustment device is disclosed. The valve comprises a first chamber configured to be connected to a fluid source, a second chamber configured to be connected to the fluid bladder, a third chamber configured to be connected to an environment, a fourth chamber connected to the first chamber via a first fluid passage, connected to the second chamber via a second fluid passage, and connected to the third chamber via a third fluid passage; and an actuator comprising a membrane disposed in the fourth chamber and an actuator element disposed in the third chamber and coupled to the membrane and configured to move the membrane between a first position wherein the first fluid passage is opened and the third fluid passage is closed, and a second position wherein the first fluid passage is closed and the third fluid passage is opened.

A car seat includes an actuator capable of changing an orientation of a rest surface of a seat back laterally by turning and moving at least a side portion frame that is part of the car seat frontward and rearward, and a controller configured to exercise control over the actuator. The controller includes a run-time posture support unit configured to execute a run-time posture support control under which when a car makes a turn, the actuator is regulated to cause the rest surface of the seat back to be oriented in a direction of the turn. The run-time posture support unit is configured to regulate the actuator in accordance with a placement of the seat in the car, when the run-time posture support unit executes the run-time posture support control.

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.

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.

Described are ergonomic passenger seats that may include monocoque or semi-monocoque seat backs, cellular suspension cushions, and tray tables with support arms that may be located within the interior volume of the monocoque or semi-monocoque seat backs when in their stowed positions. The passenger seats offer enhanced passenger comfort and space while providing a lightweight, simple to manufacture design. Monocoque and semi-monocoque seat backs may form integral parts of passenger seats to support additional loads without need for heavy, complex structures. The space within the monocoque or semi-monocoque seat back may then be used for storage or suspension cushions that offer improved comfort with a lighter seat frame. Monocoque and semi-monocoque seat backs may also facilitate the adoption of several other seating mechanisms, such as new seat mounts that allow for improved seat motion that allows for passenger recline with reduced impingement on other passengers' space.

A seat of a vehicle is designed for safety to reduce risk of injury to an occupant of the seat in the event of an abrupt movement or a collision involving the vehicle from the rear. The seat may have seatback geometry designed to promote coupling an occupant to the seat, thereby minimizing a gap between an occupant and the seatback and, therefore, the impact forces to the occupant in a rear-facing collision by reducing a relative velocity between the occupant and the seat, as well as absorbing energy of the occupant over a longer distance. The seat may include one or more materials that plastically deform under a force imparted on the seat by the occupant accelerating relative to and toward the seat during a vehicle collision. Cavities in the seat can be used, in some examples, to create a particular compressibility for optimizing impact.

A seat with a headrest for a locomotive means includes a carrier or support system for a backrest of the seat, a support element having an installation section, and a guide device. The headrest has a headrest box, wherein the installation section of the support element is arranged on the support system in a stationary manner in the region of the headrest. The headrest box is movably arranged on the guide device, and the headrest box can be locked relative to the guide device in a movement direction.

A seat for a vehicle comprising a bearing structure, which is elastically deformable, is divided into a cushion and a backrest and is obtained by means of a foam having a net-like structure. The bearing structure of the cushion has: an outer zone, which extends along the entire periphery of the cushion and has a first bearing capacity; and an inner zone, which extends at the centre, is completely surrounded – on all sides – by the outer zone and has a second bearing capacity smaller than the first bearing capacity.
