Abstract
The airbag apparatus includes a fracture-opening section of an instrument panel cover located in opposition to an opening portion of an airbag case and capable of being split apart, and a plurality of reinforcements fixedly attached to the back surface of the fracture-opening section. The fracture-opening section includes a contour portion and a splitting portion, which, in turn, include fragile portions formed through laser processing. The reinforcements are attached to the fracture-opening section in such a manner as to correspond to subsections of the fracture-opening section into which the splitting portion divides the fracture-opening section. The reinforcements each include a hinge portion and a leg portion. An end of the leg portion is engaged with a plurality of hooks fixedly attached to side edges of the opening portion of the airbag case. Upon inflation of the airbag, the fracture-opening section opens apart along the splitting portion.
