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.

An active system and a computer-implemented method for reducing vibrations of seats in a vehicle is described. The system and method adjust a damping and/or a stiffness of a vibration damper based on system input signals from the vehicle or seat system. The signals include one or more of a signal associated with a user weight, a signal associated with time-dependent movement of a vehicle frame, and a signal associated with time-dependent movement of a seat back or a seat pan. The damping or the stiffness are adjusted by a closed loop control.

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.

According to various aspects, a controller includes one or more processors configured to: determine when a predicted event occurs, at which a velocity of a vehicle is changed; and provide an instruction for a reorientation of one or more seats of the vehicle based on when the predicted event occurs.

The invention relates to a device for influencing a backward movement of a seat (1), in particular a backrest part (1.1) of the seat (1), with at least one deformation element (4) arranged in a hinged area (7) of the seating part (1.2) of the seat (1), the deformation element (4) being configured such that the deformation element can be deformed due to a force acting on the seating part (1.2) and/or the back part (1.1) at a predefined torque curve. The invention also relates to a seat (1), in particular a vehicle seat, comprising a seating part (1.2), a backrest part (1.1) and the type of device.

A vehicle assembly includes a vehicle body including a frame backing member, and a vehicle seat including a seat back having a seat back frame. An energy attenuating member is positioned in a space between the frame backing member and the seat back frame in a front-rear direction of the vehicle assembly. The energy attenuating member is connected to the frame backing member. A mounting bracket is connected to the energy attenuating member. A connection support portion releasably connects the mounting bracket to an upper portion of the seat back frame in a height direction of the vehicle assembly.

A vehicle occupant restraint system for a motor vehicle comprises a vehicle seat (14) including a seat (16) and a backrest (18), and comprises an actor (12) that is arranged to set the seat (16) relative to the backrest (18) so as to actively reduce an angle (α) between the seat (16) and the backrest (18) during crash or before crash. In addition, the invention describes a method for restraining a vehicle occupant.

The present disclosure relates to a vehicle seat that includes a seat cushion which is substantially horizontal with respect to a floor of a vehicle. The vehicle seat further includes a seat back including a proximal end and a distal end separated by a longitudinal length, such that the proximal end is pivotably coupled to the seat back. The vehicle seat also includes a track arranged adjacent to the seat cushion and the track has a longitudinal length. The track includes a proximal end and a distal end, such that the proximal end of the track is attached to a biasing element while the distal end of the track is attached to a portion of the seat back. In a crash event, the seat back is displaceable with respect to the seat cushion along the longitudinal length of the track.

The invention relates to a device for influencing a backward movement of a seat, in particular a backrest part of the seat, with at least one deformation element arranged in a hinged area of the seating part of the seat, the deformation element being configured such that the deformation element can be deformed due to a force acting on the seating part and/or the back part at a predefined torque curve. The invention also relates to a seat, in particular a vehicle seat, comprising a seating part, a backrest part and the type of device.
