Patent attributes
An airbag device is to be mounted on a vehicle and includes an outer airbag, an inner airbag and a friction generating member. The outer airbag is made of a base cloth and configured to expand and deploy outward of the vehicle. The inner airbag is made of a base cloth and configured to expand and deploy in the outer airbag. The friction generating member is provided on at least one of an inner surface of the outer airbag and an outer surface of the inner airbag. When the inner surface of the deployed outer airbag contacts the outer surface of the deployed inner airbag, the friction generating member generates a frictional force that is greater than a frictional force that is generated when the base cloths of the outer airbag and the inner airbag overlap one another.
