Abstract

The invention relates to an airbag module for a motor vehicle, having an airbag which is provided as an airbag package and can be inflated by means of a gas generator in order to protect a vehicle occupant who is located on a seat of a motor vehicle, said airbag having a sleeve which surrounds an interior of the airbag; having a module receptacle on which the airbag is accommodated as an airbag package; having a covering surface of the airbag module, which, when the airbag module is correctly installed in a motor vehicle, is arranged in the motor vehicle in such a way that the covering surface faces the assigned seat; and having an airbag module cover which extends along the covering surface. According to the invention there is provision that at least one layer (40), forming a component of the airbag sleeve, of the airbag (4) extends in front of the outer surface (21), facing the seat, of the cover (2), and that components (40, 40a), arranged in front of the outer surface (21) of the cover (2), of the airbag module remain connected to the airbag sleeve when the airbag (4) inflates provided that they are not located between the outer surface (21) of the cover (2) and the at least one airbag layer (40).
