Airbag device

Abstract

An action of once strongly pressing an airbag against a pillar trim at the initial stage of deployment is omitted to enable the airbag to be quickly inflated and deployed without reducing the deployment speed thereof. An airbag device includes a folded airbag (10) that is attached to an upper part of a side wall inside a vehicle cabin in the front-rear direction of a vehicle, and an inflator that inflates and deploys the airbag (10) to the lower side of the vehicle. The airbag (10) includes a roll-folded portion (10R) rolled from one end thereof opposite from an attaching side, and an accordion-folded portion (10J) continuous with the roll-folded portion (10R) and folded in an accordion manner. The accordion-folded portion (10J) is folded so as to be located at a side of the roll-folded portion (10R). The accordion-folded portion (10J) is formed by folding the roll-folded portion (10R) into two and making accordion folds from the two-folded portion so as to have the same width as the width (L2) of the two-folded roll-folded portion (10R).
