摘要： 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.

摘要： 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.

摘要： 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.
