Abstract

The upper, decorative layer (6) of the airbag cover (1), which can be made of leather, fabric, or a synthetic foil, has to be uninterrupted for an attractive and unobtrusive appearance. A lower, rigid layer (2) with edges in a zigzag shape (3) is positioned underneath the decorative layer (6), cutting and separating the soft material when the airbag is inflated. Hinges (4, 5) prevent the cover (1) from being blown against the driver or the passenger in case of an impact.
