Abstract

An airbag cover in a dashboard, a steering wheel hub cover, or door panel with at least one predetermined breaking line whose shape is substantially determined by a line-shaped weakened portion. The line-shaped weakened portion is a perforation line extending until approximately below the surface visible to the vehicle passengers. This perforation line is advantageously a curve alternating around the predetermined breaking line and is at least similar in shape to the structure of the visible surface.
