Patent ID: 8517415

Claim:
An airbag apparatus comprising: an airbag that is folded toward an inflator attaching part so as to narrow a width of the airbag in a lateral direction and thus forms an intermediate shape extending in a longitudinal direction with the inflator attaching part being interposed therebetween, in which parts extending in the longitudinal direction in the intermediate shape are respectively folded toward the inflator attaching part to form a first folded part and a second folded part, and that is accommodated in a case with the first and second folded parts being arranged on a cabin side from the inflator, wherein the case is provided with a tear line that is formed at a position deviated from a center of the inflator toward the first folded part and divides the case into a first door and a second door, the first door overlapping over both the first and second folded parts, the first door deploying from the second folded part, the first door serving as a first support point for the airbag when inflated, the second door overlapping over the first folded part, the second door deploying from the first folded part, the second door serving as a second support point for the airbag when inflated, wherein the second folded part is folded in a bellows shape, wherein the first and second folded parts arranged toward the cabin side of the inflator are partially overlapped between parts forming the first and second doors of the case and the inflator, wherein the first folded part and the second folded part further are partially overlapped so that a lower surface side of the second folded part is located above an upper surface side of the first folded part, and wherein the second folded part at the overlapped part is positioned more closely toward the cabin than the first folded part.
