Abstract
An airbag apparatus uses an interior panel of an automobile. The interior panel is formed of a multi-layer sheet including a surface layer, an intermediate foam layer, and a base layer. The interior panel has front and rear hinge grooves and left and right fracture grooves for defining a fracture-opening section, and a center fracture groove for dividing the fracture-opening section into front and rear fracture-opening subsections to be split apart from each other in a casement condition. The hinge grooves, the center fracture groove, and the left and right fracture grooves are formed of laser-machined holes which have different depths and do not pass through the surface layer of the interior panel.
