Abstract
An air bag door in which the remaining thickness of a substrate at a centerline of a fracture groove formed into the shape of an air bag door on a back surface of the substrate is set to be smaller than other portions, and dotted fracture perforations for braking the superficial material are selectively provided at the centerline portion and near meeting points between sidelines and the centerline. According to the invention described above, the substrate and the superficial material of the air bag door are broken in a desirable order of breakage by portions synchronously with each other when the air bag is expanded and deployed.
