A vehicle seat that includes a lateral occupant support structure that is movable based on a position of a backrest. The vehicle seat includes a lateral occupant support structure setting system that adapts a position of one or more lateral occupant support structures based on one or more of a position of the backrest and movement of the backrest.

A vehicle seat includes a cushion and a seatback coupled with the cushion and rotatable between collapsed and open positions. The seatback includes a first inflatable bladder within an interior of the seatback, a pneumatic actuator fluidically coupled with the bladder and configurable between a compressed condition and a withdrawn condition, and a control cable coupled between the actuator and the cushion for linking the configuration of the actuator with the position of the seatback.

A vehicle seat having at least one side bolster mounted to the vehicle door such that when the door is open the adjoining bolster moves away from the side of the seat to provide an easier path for ingress and egress from the seat.

A method for adjusting a vehicle seat includes moving each of a set of first valves respectively associated with ones of a group of first bladders into an open position allowing the receipt of air into and fluidic communication among the group of first bladders, inflating the first group of bladders to a predetermined pressure, and closing each of the set of first valves to maintain an inflation level of each of the first bladders.

An actuator assembly for adjusting at least one component of a seat comprises a first traction device, a second traction device, and an actuator which comprises a spindle drive. The spindle drive comprises a first member which is rotatably mounted and a second member which is threadingly engaged with the first member and secured against rotation. Both the first traction device and the second traction device are coupled to the second member of the spindle drive.

An expandable seat for a vehicle comprising a support structure movable between an expanded state and a contracted state, the support structure forming a seating region that is greater in size when the support structure is in the expanded state than when the support structure is in the contracted state, and a flexible covering movably coupled to the support structure. The support structure and the flexible covering cooperate to ensure that the flexible covering covers the seating region of the support structure when the support structure is in the expanded state and when the support structure is in the contracted state.

A seat assembly having a seat back that has a seat back frame and a shell. The seat back frame may extend through a shell opening such that an upper shell cross member is disposed on a back side of the seat back frame and a lower shell cross member may be disposed on a front side of the seat back frame.

Provided is to stabilize a fixed state of each bag body provided at a vehicle seat and configured to expand to push a corresponding one of the shoulders of a seated passenger. Of a seat back provided at the vehicle seat, each shoulder support configured to support a corresponding one of the shoulders of the seated passenger includes an air cell configured to expand by injection of air. The air cell includes protrusions extending in a predetermined direction and provided at respective end portions of the air bag in the extending direction thereof. The air cell is attached to the inside of the seat back in such a manner that each of the protrusions provided at respective end portions in the extending direction is fixed to a corresponding one of fixing positions separated from each other in the width direction of the vehicle seat.

A seat having a base support extending under a base of the seat and a squab support extending behind a squab of the seat, the squab support being integral with the base support, the seat presenting a base seating surface upward of the base support and a squab seating surface forward of the squab support, and the seat comprising a first inflatable bladder disposed between the squab support and the squab seating surface for permitting adjustment of the inclination of the squab seating surface relative to the base seating surface.

A vehicle seat comprising: a seat cushion; a seat back; an actuator capable of changing an orientation of the seat back laterally by moving a pressure-receiving member; and a controller configured to exercise control over the actuator. The controller includes a posture control unit configured to execute, during turning of a vehicle, a seat posture control under which the actuator is caused to move the pressure-receiving member from an initial position to an advanced position to cause the seat back to orient toward a turning direction. The posture control unit is configured to activate, when an execution time of the seat posture control has become equal to or greater than an execution time threshold value, a control under which the actuator is caused to move the pressure-receiving member from the advanced position to an intermediate position to reversely change the orientation of the seat back.
