Abstract: An airbag device includes an airbag that is supplied with gas generated by an inflator during a vehicle collision and that inflates and deploys from a rear side of a vehicle seat toward a front side via an upper side. In an inflated and deployed state, the airbag includes a pair of front-rear chambers extending in a seat front-rear direction via left and right sides of a head of a passenger, an airbag body that is in communication with the pair of front-rear chambers and that is disposed at a front side of the passenger between the pair of front-rear chambers, and a pair of rear tethers including one-end portions attached to the airbag body and other-end portions attached to a seatback of the vehicle seat. At least a rear tether on a side door side is configured so as to be releasable after a collision of the vehicle.

Abstract: 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 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. Gas is supplied to the airbag main body via a communication hole positioned at a seat rear side of the connecting portion of the front-rear chamber that has inflated and deployed. Owing to inflation and deployment of the front-rear chamber, the airbag main body passes through a gap between a ceiling of the vehicle and the head from the seat rear side toward the seat front side, and thereafter, inflates and deploys toward the seat rear side.

Abstract: 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 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. The airbag main body has a downward-force applying portion that applies force directed toward a seat lower side to the airbag at a time when the passenger is restrained by the airbag.

Abstract: 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.
