Abstract:
1. A vehicle airbag device comprising: a base member having an airbag deployment opening and first and second flaps each being capable of opening the opening by pivoting about respective hinge shafts provided at opposing edges of the opening; a skin member layered on the base member; a tear seam for breaking in correspondence with the flaps by deployment of an airbag, the tear seam being formed in the skin member in the direction of axis lines of the hinge shafts and including a main portion extending across the opening and first and second extended portions extending to regions outside the opening; and detaching parts formed in the skin member along the first and second extended portions of the tear seam so as to be detached from the base member by the flaps, wherein the tear seam is disposed closer to the axis line of one hinge shaft of the pair of hinge shafts than the other hinge shaft, and wherein the first flap is formed as an outward-curving door in which a width from both ends of a free end of the first flap to the hinge shaft is minimized, and the second flap is formed as an inward-curving door having a shape in which a free end of the second flap matches the free end of the first flap.
