An airbag device having a cushion stowed, rolled or folded at an upper part of a side surface inside a vehicle cabin configured to expand and deploy along the side surface, the airbag device comprising:
- an inflator inserted inside the cushion that supplies gas to the cushion;
- wherein
- the cushion including:
- a duct having a tab at the upper part of the side surface for suspending the cushion from the upper part of the side surface, the duct extending in a front-to-back direction of a vehicle and adapted to expand and deploy with inflowing gas, a main chamber positioned below the duct, and a sub chamber provided at the upper part of the side surface;
- an upper end of the sub chamber positioned above an upper edge of a side window;
- and
- a lower end of the sub chamber positioned below an upper end of the duct;
- and
- wherein the sub chamber is formed in a bridge shape with a pair of legs separated in the front-to-back direction and connected to the duct and a connecting part that connects the pair of legs and the tab is attached in a portion of the duct positioned between the pair of legs;
- and
- wherein the sub chamber further includes a blocking part for blocking one of the pair of legs from the duct.
