摘要： In a shielding state, a partition extends from an upper portion to a lower portion of a cabin in such a manner as to partition a space between a pair of opposing vehicle seats. In the case where the partition is in the shielding state during a collision of a vehicle, the partition is inflated in a vehicle longitudinal direction by gas supplied from an inflator that is actuated when a collision detection sensor detects the collision of the vehicle. That is, since the partition is inflated in the space between the pair of the vehicle seats without interfering with the vehicle seats, the partition can reliably restrain an occupant who receives a collision load and is thereby displaced in the vehicle longitudinal direction from the vehicle seat. In this way, it is possible to easily secure a private space in the cabin and to improve occupant restraint performance.

摘要： A vehicle seat is provided with a wire that, in the event of a vehicle frontal collision, enables a pulling load applied by a vehicle occupant to a webbing to be transmitted between a cushion frame of a seat cushion and a movable rail of a sliding device. One end portion of the wire is anchored to a first anchoring member of the movable rail, while another end portion of the wire is anchored to a second anchoring member of the cushion frame.

摘要： An occupant protecting device for a vehicle has a knee airbag that is disposed at a seat front side of a vehicle seat, and that, at a time of a front collision of a vehicle, deploys, and restrains leg portions of a vehicle occupant seated in the vehicle seat. A foot airbag is disposed at the seat front side of the vehicle seat. At a time of a front collision of the vehicle, when a seat front-rear direction position of the vehicle seat is disposed further toward a rear side than a predetermined position, the foot airbag deploys between the knee airbag and the leg portions of the vehicle occupant seated in the vehicle seat, and restrains the leg portions of the vehicle occupant seated in the vehicle seat.

摘要： An occupant protection system includes a seat disposed such that a rear surface of a seatback in a seat front-rear direction faces a wall portion of a vehicle cabin; an airbag provided in the wall portion or the seatback and configured to support the seatback by inflating and deploying between the wall portion and the seatback; and an inflator configured to generate gas to be supplied to the airbag in a case where a collision that causes an occupant seated in the seat to inertially move rearward in the seat front-rear direction is detected or predicted. The airbag has a vent hole through which the gas inside the airbag is discharged outside.

摘要： 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.
