Provided is a seat frame for a vehicle seat capable of supporting the back of a seated person during a rear-end collision by using a simple structure and few component portions. The seat frame includes a top frame portion on the top of the seat, lateral frame portions on the right and left of the seat, and a connection frame connecting the tops of the lateral frame portions to bridge them. The connection frame includes a bent protrusion portion bent in the longitudinal direction and arranged in a standing condition from a surface formed by the connection frame, at a position between a pair of the lateral frame portions. The bent protrusion portion is provided over the entire length of the up and down direction of the connection frame.

An air-bag apparatus includes: a frame member that is tiltable along a seat back of a vehicle seat; and a bag body that is embedded in the frame member, that is inflated and expanded to a front of an occupant seated on the vehicle seat at a time of an impact input, and that prevents a body of the occupant from being separated from the seat back.

A seat back structure for a vehicle according to one aspect of the present invention including a headrest, a seat back frame, a pad disposed in front of a surface of the seat back frame, a backrest surface of the pad, and right and left side supports each provided on either side of the backrest surface in a seat width direction, in which a right slit portion and a left slit portion are provided between the backrest surface and the right and the left side supports, respectively, each of the right slit portion and the left slit portion penetrating the pad in the thickness direction of the pad and extending in a vertical direction of the pad, and the right and the left slit portions are spaced apart from each other in the seat width direction.

A deformation element for a motor vehicle seat, which element is intended to be arranged on a subassembly of a motor vehicle seat, having a base member, a deformation portion which is formed on the base member and on which the deformation element can be deformed and/or destroyed under the action of an external force, and a force introduction region by means of which a structural element of a motor vehicle seat can be brought into operational connection with the deformation portion so that a force acting on that structural element can be introduced via the force introduction region into the deformation portion. The deformation portion is formed by means of partial deformation of the material of the deformation element and at the transition of the deformation portion to the base member of the deformation element there is a weakening region which defines at least one tear line.

A connecting element for a vehicle seat includes a body on which a backrest and a seat cushion of the seat are intended to be mounted. The body has a first edge and at least a first through slot extending longitudinally along a first direction from the first edge and defining a first inner end. The connecting element further includes a first bridge extending along at least a portion of the first edge opposite the first slot, with the first bridge having a curved shape.

An occupant protection apparatus includes: a vehicle seat arranged in an inner space of a side wall of a vehicle; a side airbag device provided in the side wall or the vehicle seat and including a side airbag to be inflated and deployed between the side wall and the vehicle seat. The vehicle seat includes: a pressure-receiving portion to receive a load from an occupant seated on the vehicle seat; and a frame to support the pressure-receiving portion. The occupant protection apparatus further comprising an electronic control circuit configured to perform moving the pressure-receiving portion so that the occupant is pushed away from the side wall before the occupant comes into contact with the side airbag at an activation time when the side airbag device is activated by an impact acting on the side wall from an outside of the vehicle and the side airbag is inflated and deployed.

A rear-facing occupant protection device is provided. The rear-facing occupant protection device is applied to a vehicle in which a seatback of a front seat is mounted in a rear-facing state in which a back surface of the seatback faces a vehicle-body-side vertical wall portion disposed at a front end of a vehicle cabin, or mounted such that the seat back is capable of taking the rear-facing state. The rear-facing occupant protection device includes: an energy absorbing portion disposed on at least one of a back surface of a seatback pad of the seatback and a rear surface of the vehicle-body-side vertical wall portion, the energy absorbing portion being configured to be deformed so as to absorb energy at a time of a frontal collision of the vehicle.

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.

Provided is a conveyance seat that effectively reduces a load to be applied to an occupant at the time of a vehicle collision. A conveyance seat includes a seat back and a headrest. The seat back includes a chest support member inside the seat back, which receives a chest of an occupant to support the chest of the occupant when a backward movement load is applied to the occupant because of a vehicle collision. The headrest includes a head support member inside the headrest, which receives a head of the occupant to support the head of the occupant when the backward movement load is applied to the occupant. When the backward movement load is applied to the occupant, both the chest support member and the head support member receive the backward movement load.

A seat backrest includes right and left side frame segments, a pressure receiving member disposed between the side frame segments movably in a front-back direction, and a cushion pad covering the front of the side frame segments and pressure receiving member. The pressure receiving member includes a main body part, and extending parts extending laterally from both sides of the main body part. The cushion pad includes a back receiving part covering the front of the main body part, and bank parts disposed on both sides of the back receiving part, protruding forward from both sides, and covering the front of the extending parts and side frame segments. A recess is formed at an area, facing a corresponding extending part of the extending parts, of a rear surface of each bank part.
