Patent attributes
An airbag device includes an inflator, an airbag, a holding member, and a gas rectifying member. The holding member has an opening to be formed at least when the airbag initiates to inflate. The holding member restricts the inflation of the airbag toward its outer periphery until the middle of the deployment of the airbag. The gas rectifying member restricts a flow of a gas toward an occupant and has an outlet port that discharges the gas toward the outer periphery of the airbag. When the airbag inflates, the gas rectifying member projects toward the occupant through the opening of the holding member, and the gas of the inflator causes the gas rectifying member to inflate until at least part of the outlet port is located at the occupant side beyond the opening of the holding member.
