A vehicle seat includes: a seat main body that includes a seat cushion and a seatback that is connected to a seat rear side end portion of the seat cushion and that is rotatable in a seat front-rear direction with respect to the seat cushion; and a lifter device that moves the seat main body in a seat up-down direction, wherein the seat main body is moved toward a seat upper side by the lifter device in a case in which a reclining angle of the seatback is greater than a predetermined angle and the seat main body is lower than a predetermined height.

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 vehicle seat comprises a frame member provided on a floor of a vehicle, a seat part such as a seat cushion detachably attached to the frame member, a mechanical connector device provided on the frame member and the seat part for detachably attaching the seat part to the frame member; and an electric connector device provided on the frame member and the seat part for electrically connecting an electric component provided on the seat part to an electric component provided on the frame member.

The disclosure provides for a system that includes a seat mounted in a vehicle. The seat includes a base, a back support, a hinge, and a seat belt integrated into the seat. The back support is capable of rotating relative to the base and thereby reclining. The hinge is between the base and the back support and is configured to lock the back support in positions in relation to the base. The seat belt has a shoulder portion and a lap portion and is attached to the seat at a shoulder anchor in the back support and a base anchor in the base. When a generated torque, created from a forward force applied by the shoulder portion of the seat belt, exceeds a threshold amount of torque, the hinge is configured to unlock and back support is configured to rotate forward from a reclined position towards an upright position.

A seat having 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 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 due to accident or explosive events and is capable of automatically resetting.

Vehicle seat fixed to the floor of a cabin of a vehicle and which is able to absorb the impact of a passenger seated behind. It comprises at least two uprights (20) per backrest, these being positioned substantially vertically and engaged via a lower end (30) in the fixed framework (32) of the seat in such a way as to be releasable through upward translational movement so that they can disengage upward under the effect of an impact on a rear face, and are mounted with the ability to rotate about at least one fixed axis of the fixed framework (32) so as to be able to pivot forwards after becoming disengaged. At least one deliberate mechanical weak link positioned between each upright (20) and the framework (32) blocks the translational movement of the upright below a determined force corresponding to the impact. Application to aircraft seats.

An energy absorber (100) for a vehicle seat (1), in particular for a linear adjuster (60) of the vehicle seat (1), includes a deformation element (110). The deformation element (110) is deformable by forces occurring in a vehicle collision. The energy absorber (100) includes a bending element (120) that releases the deformation element (110). Upon achieving a bending load acting on the bending element (120), the bending element (120) bends and the bending element (120) thereby releases the deformation element (110) to a lesser extent. A linear adjuster (60) for a vehicle seat (1) is also provided, having the energy absorber (100). Further, a vehicle seat (1) is provided having at least such one linear adjuster (60).

A method for adjusting a position of a vehicle seat from a reclined position to a pre-determinable safety position. The method includes detecting an imminent or ongoing frontal or semi-frontal collision, pretensioning a seat belt associated with the vehicle seat, the seat belt being directly or indirectly attached to a backrest of the vehicle seat, and adjusting the position of the vehicle seat from the reclined position to the pre-determinable safety position by means of a seat adjustment means associated with the vehicle seat, the seat adjustment means being actuated by a collision force generated by the imminent or ongoing frontal or semi-frontal collision and applied via a seat occupant and/or the seat belt to the vehicle seat. The present invention also relates to an occupant safety arrangement for a vehicle seat.

A vehicle occupant protection device, that includes: a vehicle occupant protection control unit that, in a case in which a rear impact of the vehicle is predicted, effects control such that a seat of the vehicle approaches a rear impact protection attitude that protects a vehicle occupant from a rear impact, and that, in a case in which the vehicle is forcibly stopped, effects control such that a driver seat of the vehicle approaches closer to the rear impact protection attitude than in the case in which a rear impact of the vehicle is predicted.
