Abstract

An airbag device for a vehicle, including an airbag package, a receptacle, and a flexible protective covering for the airbag. The flexible protective covering includes at least two flexible, sheet-like protective elements secured to the receptacle. The flexible, sheet-like protective elements are connected to one another via at least one separable tearing line. The flexible, sheet-like protective elements flank the airbag during initial inflation and expansion of the airbag. A flexible guide layer is arranged between the protective covering and the airbag package. The flexible guide layer is permanently connected to a first of the sheet-like protective elements, such that the first sheet-like protective element, together with the guide layer, forms a composite layer flanking the airbag during inflation.
