A seating system for a vehicle includes a seat frame having a lower part for supporting a posterior and thighs of an occupant and a rear part for supporting the posterior and back of the occupant. The seating system also includes a hinge connecting the seat frame to the vehicle such that, in the event of an impact to the vehicle from the rear of the occupant, the weight of the occupant urges the seat frame to rotate in a direction that results in a top portion of the rear part being urged to move in a rearward direction relative to the occupant. The seating system also includes a first structure fixed to the rear part and configured to cooperate with a second structure fixed to the vehicle to reduce forces transmitted to the occupant in the event of an impact to the vehicle.

A multi-direction power actuated head restraint assembly includes a head restraint mountable to a vehicle seat. The head restraint assembly also includes a fore-aft power actuation mechanism including a fore-aft electric motor to adjust a fore-aft position of the head restraint, the fore-aft electric motor programmed to adjust the fore-aft position at a first fore-aft speed during manual adjustment of the head restraint and at a second fore-aft speed upon detection of an imminent impact by an impact detection system, the second fore-aft speed greater than the first fore-aft speed.

A seat including a seat bottom, a seatback, and a device. The device supports the seatback on the seat bottom. The device includes a housing supported on the seat bottom and a rotor supported on the housing. The device includes a helical interface between the housing and the rotor. The rotor is moveable relative to the housing along the helical interface. The housing and the rotor define a cavity therebetween, and a resilient material is disposed in the cavity. During a vehicle impact, the rotor may move relative to the housing and compress the resilient material in the cavity. In this situation, the resilient material may absorb energy from the vehicle impact.

Various seating arrangements for a vehicle are described. Generally, the vehicle includes an electromagnetic array featured on a floor of the vehicle. The chair includes base having a plurality of magnets featured thereon. The vehicle generates signals for the electromagnetic array to generate a wave and impart a force on the chair in a determined direction via the plurality of magnets.

A vehicle seat (1) includes a seat cushion (2) and a seat back (3), in which the seat cushion (2) is given a stiffness distribution in a front-rear direction in such a way that a front part of the seat cushion is provided with a low stiffness region (PSc) which is more flexible than a rear part of the seat cushion being a high stiffness region (PHc).

A vehicle seating system includes a seat bottom and a seat back pivotably connected to the seat bottom. A first motor may operate to pivot the seat back relative to the seat bottom with a first gearing. A second motor may operate to pivot the seat back relative to the seat bottom with a second gearing. A transmission member may be disposed between the first motor and the second motor such that operation of the first motor drives the first gearing and rotates the elongate transmission member, thereby driving the second gearing.

An impact absorption assembly for a seat back is provided having a deformation zone as least partially disposed above a top surface of a seat back structure. The deformation zone deforms plastically upon an impact from a rearward direction.

A seat includes a seat-bottom frame, a seat-back frame rotatable relative to the seat-bottom frame between a forward position and a rearward position, and a first wedge and a second wedge on opposite side of the seat-back frame. The first wedge extends from the seat-back frame in the forward position to the seat-bottom frame, and the second wedge extends from the seat-back frame in the rearward position to the seat-bottom frame.

A vehicle seat includes a pressure-receiving member disposed rearwardly of an occupant between left and right side frames, and a rocking mechanism configured to cause a left side or a right side of the pressure-receiving member to move frontward and rearward. The rocking mechanism includes a first link member provided pivotally, a second link member provided pivotally on the first link member and pivotally connected to the pressure-receiving member, and an actuator configured to cause the first link member and the second link member to pivot.

A vehicle seat includes a back frame mounted on a cushion frame is a recliner in a pivotally movable manner. The back frame has a support member connected to the recliner, and a seat back shell supported by the support member. The support member has a side plate portion and a rear plate portion facing a side surface and a rear surface of the seat back shell, respectively, and the side plate portion has a base portion fixed to the recliner, and an extension portion provided to extend more upward than the base portion. The side plate portion is fixed at the extension portion to the side surface of the seat back shell, and the rear plate portion is at least fixed in a region to the rear surface of the seat back shell, the region provided to rise from a lower position of the side plate portion.
