A kinetic seat assembly that rotates based on a force applied on an occupant seated therein is provided. The kinetic seat assembly includes a primary seat cushion frame, a primary seat back frame, a secondary seat cushion frame pivotally connected to the primary seat cushion frame, and a secondary seat back frame pivotally connected to the primary seat back frame. The kinetic seat assembly further includes a front pivot mechanism for damping movement between the primary seat cushion frame and the secondary seat cushion frame in a kinetic seat vertical direction, and an upper pivot mechanism for damping movement between the primary seat back frame and the secondary seat back frame in a kinetic seat longitudinal direction.

An occupant protection apparatus includes a driver. The driver includes a drive unit, a support shaft, a movable seat pan supported by the support shaft such that the movable seat pan is inclinable in a front-rear direction, a guide groove, a movement pin that is movable along the guide groove, a link that couples the movable seat pan to the movement pin, and an energy absorber. The guide groove includes a first guide groove portion in which the movement pin moves when the movable seat pan is inclined rearward and a second guide groove portion in which the movement pin moves when the movable seat pan is inclined forward. The energy absorber is configured to absorb at least part of a forward load from an occupant when the movement pin moves in the second guide groove portion.

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.

A shock absorber is provided to absorb an impact load in a vehicle. The shock absorber includes a base disposed on a frame of a vehicle. The base has a first part and a second part. The shock absorber further includes a bracket coupled to the base. The bracket includes a first portion with a flat surface and a second portion with an arcuate surface. The first portion is coupled to the first part of the base, and the second portion is coupled to the second part of the base. The shock absorber further includes a cover to enclose the bracket. The cover receives an impact load and transmit the received impact load to at least one of: the first portion or the second portion of the bracket.

A vehicle includes a vehicle ceiling, a vehicle floor, and a vehicle seat assembly that couples with the vehicle ceiling and the vehicle floor. The vehicle seat assembly includes a seat support that supports a vehicle seat from the vehicle ceiling, a base that forms a slip joint with the seat support from the vehicle floor, and a set of limit straps constructed and arranged to limit deflection of the slip joint in response to deformation between the vehicle ceiling and the vehicle floor (e.g., a vehicle collision, deformation between the vehicle ceiling and the vehicle floor possibly due to a blast, etc.). Each limit strap of the set of limit straps has a first end that attaches to a portion of the slip joint and a second end that attaches to the vehicle floor.

A bracket for attaching an actuator is easily bonded to a side frame while avoiding interference with a shaft for driving a reclining mechanism. In a seat side frame which is provided at each of both ends of a seat back frame in the width direction, a reclining mechanism, and an actuator, the reclining mechanism is attached to a side wall of the side frame, and the actuator is fixed to an attachment bracket bonded to an inner surface of a portion to which the reclining mechanism is attached in the side wall in the width direction. An upper portion which is disposed above the attachment portion of the reclining mechanism and a lower portion which is disposed below the attachment portion thereof are connected to each other at the rear ends thereof and are separated from each other at the front ends thereof.

A seating posture is stabilized for the shoulders of a passenger seated on a vehicle seat. A vehicle seat is provided with a seat back configured to support the seated person from the rear. A shoulder support portion of the seat back configured to support a corresponding one of the shoulders of the seated passenger includes an air cell configured to expand when air is supplied. When the air cell expands, one end portion of the shoulder support portion on the outside in the width direction of the vehicle seat moves more forward than the other end portion of the shoulder support portion on the inside in the width direction.

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.

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.

Disclosed is a seat rail pair (2) for adjustment of a vehicle seat (8), in particular of a motor vehicle seat, in an adjustment direction (x), comprising a guide rail (10) extending parallel to the adjustment direction (x) for fastening to a vehicle floor, and a fastening rail (21), which is adjustably guided on the guide rail (10) in the adjustment direction (x) for fastening the vehicle seat (8), wherein an energy absorber element (5) is provided in a path, which introduces the force acting on the vehicle seat (8) into the vehicle structure, which energy absorber element permits a movement of the vehicle seat in the adjustment direction (x) under plastic deformation when a predetermined value of the force is exceeded.
