A vehicle seat 10 has a seat cushion 12, a seatback 14, a fixed supporting portion 24, and a movable supporting portion 26 that is supported by the fixed supporting portion 24 movably at least toward a seat rear side. Further, the vehicle seat 10 has an energy absorbing member 28 that, by being provided between the fixed supporting portion 24 and the movable supporting portion 26, restricts displacement of the movable supporting portion 26 with respect to the fixed supporting portion 24, and, due to the seatback 14 being pushed toward the seat rear side at a time of a collision of a vehicle, the energy absorbing member 28 is deformed and the movable supporting portion 26 is displaced with respect to the fixed supporting portion 24.

A vehicle seating assembly including a seat cushion and a seat frame assembly with a carrier assembly and a displaceable platform coupled to the carrier assembly and selectively deployable from a design position to a fully deployed position in response to a sudden deceleration of the vehicle.

A vehicle seat includes a pelvis movement suppression member, a moving mechanism, a control section and an energy-absorbing mechanism. The pelvis movement suppression member is disposed at a seat upper side of a seat front side of a seat cushion, extends in a seat width direction, and is movable in a seat front-rear direction relative to a frame of the seat cushion. The moving mechanism moves the pelvis movement suppression member from an initial position to a restraining position at a seat rear side relative to the initial position. When a collision is detected or predicted, the control section activates the moving mechanism and moves the pelvis movement suppression member to the restraining position.

A seat rail module for a vehicle seat, comprising two longitudinal adjustment rails (10) arranged parallel to each other for guiding the vehicle seat (1) and adjusting its position in longitudinal direction, deformation units (18) which can be fastened or are fastened to the longitudinal adjustment rails (10), and fastening members (25) for fastening the seat rail module to the floor of a vehicle body, wherein the vehicle seat (1) can be fastened to the longitudinal adjustment rails (10) and the deformation units (18) are configured for deforming deformation members (19) when the vehicle seat is displaced in a main direction of travel, in order to decelerate the vehicle seat in the event of a crash, characterized in that the fastening members (25) are configured to fasten the seat rail module to the floor of the vehicle body by means of locking, and in that the fastening members (25) are mechanically unlocked when the vehicle seat (1) is displaced in longitudinal direction in the direction opposite to the main direction of travel beyond a predetermined limit line (8).

Also in the rear area in which the vehicle seat assumes a seat position which is shifted relatively far backward, such as will be possible in the future for autonomous driving or as a relax position, precautions for occupant protection are provided to a sufficient extent, even if front occupant protection systems, in particular front airbags, are no longer effective in this area.

A conveyance seat unit lessens a neck load applied to an occupant based on body shape, sex, or the like of the occupant when a rear load acts on a conveyance. The conveyance seat unit includes: a seat having a support portion that supports the occupant from behind; a state adjustment mechanism configured to adjust a state of a neck load adjustment portion, of the support portion, that affects the neck load applied to the occupant when the rear load acts on the conveyance; and an electronic control unit (ECU) that controls the state adjustment mechanism. The ECU acquires occupant information on the body and the sex of the occupant and controls the state adjustment mechanism according to the acquired occupant information to change the state of the neck load adjustment portion, which has been adjusted by the state adjustment mechanism, according to the content of the occupant information.

An adjustment mechanism for a vehicle seat includes an actuator and a driven member. The actuator is coupled to the driven member to cause the driven member to move or be freed to move in response to activating the actuator.

A vehicle with a vehicle seat arranged in the vehicle interior, which is paired with an occupant protection system, which has at least one crash detection sensor system that detects at least one acceleration value in the event of a crash, which influences the vehicle in the event of a crash so that inertial forces act on the vehicle seat connected to the vehicle and on the occupant sitting on the vehicle seat on the basis of an acceleration value, wherein the acceleration value is used for the crash-adaptive specification, over time, of said displacement travel of the occupant secured with a belt system on the vehicle seat. A total displacement travel of the vehicle seat in the travel direction comprises an additional, exclusively crash-active displacement travel adjoining a displacement travel of the vehicle seat for seat length adjustment in the travel direction.

A vehicle seat, which is provided with a collision prediction sensor and with a seat cushion having a seat cushion top face and a seat cushion frame, includes: a pelvis movement suppression member disposed along a seat width direction inside a front portion of the seat cushion; a vertical movement-enabling unit supporting the pelvis movement suppression member at the seat cushion frame and allowing vertical movement of the pelvis movement suppression member to follow vertical movement of the seat cushion top face; and a stopper unit attached to the seat cushion frame and, in a case in which a rapid deceleration of a vehicle is detected or a collision of the vehicle is predicted by the collision prediction sensor, restricting downward movement of the pelvis movement suppression member.

In one embodiment there is disclosed an energy attenuating vehicle seat. The seat includes a seat back pivotally connected to a seat pan, the seat back and the seat pan independently pivotal. At the pivot between the seat back and the seat pan there is a rotary energy attenuation device. The device extends between the seat back longitudinal members and the seat pan longitudinal members and is pivotally attached to the seat pan and the seat back allowing individual adjustment of the back or pan. The rotary energy attenuating device cooperates with a track system along the length of seat longitudinal members allowing for different directions of travel and height adjustment. The vehicle seat offers passive or active protection from impact and sudden acceleration (G force and Pressure Wave) due to accident or explosive events and is capable of automatically resetting.

A vehicle seat cushion for a vehicle that includes a seat cushion support structure, and a lattice-structured support that is supported by the seat cushion support structure. The lattice-structured support provides a first resistive force in response to a vertically applied force that is less than a second resistive force in response to a force aligned with an H-point travel path of the vehicle occupant during a vehicle impact event.
