A curtain airbag device includes an airbag including, on one end side in a vehicle front-rear direction, an inflation portion configured to be inflated by a gas, and a non-inflation region into which the gas does not flow. In a state where the airbag is inflated and deployed, the non-inflation region covers a part of an opening among the plurality of openings, and the inflation portion is disposed to surround the non-inflation region, the opening being located at endmost in a vehicle longitudinal direction. In a case where an impactor strikes the opening located at the endmost, the impactor comes into contact with the non-inflation region, and a lower inflation portion of the inflation portion is sandwiched between a lower end of the impactor and the interior materials of the vehicle side portion, the lower inflation portion being located on a vehicle lower side of the non-inflation region.

An airbag device includes an inflator configured to generate gas, a first panel including an edge portion, a first fixing portion, and a second fixing portion, the second fixing portion facing the first fixing portion, a regulating member provided inside the airbag. The regulating member includes a first portion fixed to the first fixing portion, and a second portion fixed to the second fixing portion. A length from the first fixing portion to the second fixing portion is longer than a length from the first portion to the second portion. The airbag includes main bag, and a sub inflation portion. In a state where the airbag is inflated and deployed, gas from the inflator is introduced into the main bag, the first panel faces an occupant, and the sub inflation portion receives the occupant.

Airbag device

The side airbag device includes an inflator and a side airbag that is stored in a folded state in a side portion of a seatback of a vehicle seat and is inflatable and deployable in a space between a vehicle sidewall and a side portion of an occupant. The side airbag includes an outer bag and an inner bag. The inner bag houses the inflator and is disposed at a rear portion of the outer bag along an extending direction of the seatback. The outer bag is provided with a vent hole configured to communicate with an outside. The inner bag is provided with a gas circulating hole configured to communicate with the outer bag. The gas circulating hole is disposed at a position to be blocked by the outer bag when the side airbag in an inflated and deployed state is pressed between the occupant and the vehicle sidewall.
