An airbag device has an airbag. The airbag has a front-rear chamber and an airbag main body. The front-rear chamber has a left and right pair of front-rear extending portions that pass by respective left and right sides of a head of a passenger seated in a vehicle seat and inflate and deploy toward the seat front side, and a connecting portion connecting front end portions of the pair of front-rear extending portions in a seat left-right direction. The airbag main body inflates and deploys toward a side of the passenger at a seat rear side of the connecting portion, later than the front-rear chamber. At a time when the passenger is restrained, the airbag main body is compressed in a seat front-rear direction while stretching the front-rear chamber in the seat front-rear direction.

An active bolster for a vehicle is provided, wherein the bolster comprises an expansible hollow interior that is inflatable and is self-supporting in both an inflated and in an uninflated position. The bolster has an inflator module for inflating the expansible hollow interior. The bolster has an inner wall for projecting inwardly into the vehicle and away from the side of the vehicle on inflation of the expansible hollow interior. The bolster may have a relatively non-expansible component located between a first expansible chamber and a second expansible chamber. The bolster may comprise an outer wall having an attachment portion for attaching the outer wall to a portion of the side of the vehicle.

A restraint system includes a seatback an airbag. The airbag includes two lateral portions and a central chamber connecting the lateral portions. When the airbag is inflated, each lateral portion includes a plurality of lateral chambers arranged consecutively from the seatback to the central chamber, and the lateral portions and central chamber define a gap positioned directly above and directly in front of space for a head of a 50th-percentile dummy sitting against the seatback.

A vehicle seat structure that includes: a seatback that is provided at a seat rear side of a seat cushion so as to be able to tilt in a seat front-rear direction with respect to the seat cushion, and that can support an upper body of a vehicle occupant; a headrest that is provided at a side of the seatback, which side is opposite from a side at which the seat cushion is located, and that can support a head portion of the vehicle occupant; and shoulder restraining portions that are provided at the headrest or at the headrest side of the seatback, and that, by protruding out toward a vehicle occupant side at a time of an emergency of a vehicle, restrain both shoulders of the vehicle occupant in a case in which the vehicle occupant has moved along the seatback toward the headrest side.

A vehicle seat includes a seatback, a headrest and an airbag unit. The seatback has a front side and a rear side. The headrest is connected to the seatback by at least one post and is adjustable relative to the seatback in a vertical direction. The airbag unit is carried by the seatback and includes an airbag and an inflator. The airbag is rearwardly deployable from the rear side of the seatback from a stored position proximate an upper end of the seatback. The at least one post is oriented relative to the airbag unit in a position selected from a group consisting of a first position in which the at least one post includes a lower end vertically above the airbag unit with a line along an elongated axis of the at least one post intersecting the airbag unit and a second position on which the at least one post is laterally spaced from the airbag unit.

A vehicle seat, which is provided in a vehicle equipped with a head portion protecting airbag that protects a head portion of a vehicle occupant at a time of a side collision, includes: a head portion restraining portion that is provided at an upper portion side of a seatback so as to be able to tilt rearward from an upright state, and that restrains a head portion of a vehicle occupant, wherein, when the seatback is tilted rearward beyond a predetermined angle with respect to a vertical direction, the head portion of the vehicle occupant can be protected due to at least a side portion that is at a vehicle transverse direction outer side of the head portion restraining portion covering a side of the head portion of the vehicle occupant.

A vehicle seating assembly is provided herein. The vehicle includes a seat-base. A seatback is coupled to the seat-base. An airbag assembly is coupled to the seatback and configured to deploy therefrom. A tether is coupled to the airbag assembly and at least one of the seatback and the seat-base. The tether is configured to bias the airbag assembly seating-assembly-downward when the airbag assembly is in a deployed position.

A vehicle occupant protection device has an airbag main body that is formed as a single integrated bag body that covers a head portion of a vehicle occupant and includes a forward-inflating portion housed in a headrest or in a seat back of a vehicle seat, and which inflates and deploys when supplied with gas, and which inflates on a seat front side of the head portion, and a pair of left and right side-inflating portions which inflate on seat side portions of the head portion. This vehicle occupant protection device also has a sub-bag portion that is provided in at least one of the forward-inflating portion and the side-inflating portions, and that, when an internal pressure inside the airbag main body reaches a predetermined value or greater, inflates after receiving an inflow of gas from at least one of the forward-inflating portion and the side-inflating portions.

A passenger protecting device including: an airbag device including an airbag that receives a supply of gas from an inflator and is inflated and expanded, by a front expanding portion that includes a front inflating portion to be inflated and expanded at a seat front side of the head portion and at least one of a chest portion and shoulder portions of the passenger, and a pair of left and right lateral expanding portions that include lateral inflating portions that are connected to the front expanding portion and are inflated and expanded at sides of the head portion of the passenger; and a position changing device that changes an inflated and expanded position of the airbag in a seat transverse direction, in accordance with a direction of collision of a collision body with respect to the vehicle seat.

A headrest airbag for a vehicle is provided. The headrest airbag has an airbag cushion that is deployed forward from a headrest to surround an occupant's head which minimizes the occupant's head movement by holding the occupant's head in advance thus protecting the occupant's head against impact Further, a rear cushion is deployed backward from the headrest, whereby both a front seat occupant and a rear seat occupant are safely protected from impact by preventing an injury caused when the rear seat occupant hits the front seat
