Abstract
The invention is directed to a method for introducing a predetermined break line in a multilayer airbag covering with a carrier layer, a supporting layer and a decorative layer by a laser. In order to prevent an undesirable burning of the supporting layer over a large area as a result of the occurring combustion gases, it is suggested that the carrier material is ablated by a width that is greater than the diameter of the impinging beam to facilitate the escape of the combustion gases.
