Abstract: An airbag device provided with an airbag and inflator integrally covering the head and side sections of an occupant seated in a vehicle seat. The airbag, includes, during expansion and deployment, a head protecting chamber that covers the head of the occupant and side protecting chambers that cover the side sections of the occupant, and is stowed in a rolled state, for example, from a first side of the backrest of the vehicle seat to the second side over the upper portion. An additional folding part is provided on the outer periphery of the airbag extending from the attachment end side to the backrest so as to cover at least a part of the outer periphery of the airbag on the side opposite to the seated occupant.

Abstract: An airbag that prevents heavy interference with the head of an occupant during expansion and deployment even when the occupant is not seated in a vehicle seat in a regular position.
An airbag device 11, including an airbag 12 and an inflator 6 for supplying gas to the airbag 12. The airbag 12 is positioned to the sides of the center in the left-right direction of the vehicle seat 2 and has a pair of chambers 1a physically coupled by a coupling section 12a that deploy forward of the occupant 3 when expansion and deployment are complete. The pair of chambers 1a are respectively independent during expansion and deployment and expand and deploy frontward from both the left and right sides of the vehicle seat 2, having side protecting chambers 1 ab that cover at least the side sections 3b of the occupant 3. The side protecting chambers 1ab are coupled by coupling sections 12a positioned to the sides of the center in the left-right direction of the vehicle seat 2, and the coupling section 12a is thinner than the side protecting chambers 1ab at least during initial expansion and deployment.

Abstract: For example, even when an occupant is seated offset in a left-right direction, an airbag is reliably expanded and deployed. An airbag device contains: an airbag that protects at least a side portion of a shoulder region, upper arm region, and chest region of an occupant seated on a vehicle seat; and an inflator that supplies gas to the airbag. The airbag has a pair of side part protection chambers that are housed on at least both left and right sides of the vehicle seat. The side part protection chambers, when expanded and deployed, expand and deploy forward independently from both left and right sides of the vehicle seat. A pair of the inflators are provided to allow gas to be supplied to each side part protection chamber, and the ignition timing of the inflators can be controlled separately.

Abstract: When an occupant has moved from a normal seating position, a case can occur where a hood-type airbag cannot be expanded and deployed since the airbag is stopped in the process of expansion and deployment due to contact with the head of the occupant. An airbag device is provided having an airbag, and an inflator for supplying gas to the airbag. In an expanded and deployed state where expansion and deployment of the airbag has been finished, the airbag includes a head protection chamber for blanketing an occupant from a vertex part of the head to a temporal part of the head, and a pair of lateral part protection chambers that are arranged on both of the left/right sides of the head protection chamber and that blanket lateral sides of the occupant.

Abstract: [Problem] To provide an airbag apparatus in which the injury value of a passenger can be efficiently suppressed in an emergency.
[Resolution Means] A typical configuration of an airbag apparatus 100 according to the present invention includes: an inflator 118 which is installed in a vehicle so as to be capable of supplying gas; an inner bag 112 which is expanded from in front of a seat utilizing the gas; and an outer bag 110 to which the gas is supplied from the inflator 118 or via the inner bag 112 and expanded so as to surround the inner bag 112. The outer bag 110 includes an opening 116 which exposes the inner bag 112 towards the seat 104, wherein the inner bag 112 has a more elongated shape in the anteroposterior direction of the vehicle than in the width direction of the vehicle, and the inner bag 112 further includes a restraining part 114 which is exposed on the recessed surface from the opening 116 to the seat side.
