A flexible wrapping of an airbag (16) of a vehicle occupant restraint system (10) comprises a holding compartment for a folded airbag package (14) formed by a holding bag (104) and an airbag package fixation (124), an inflator fixation (114) formed by projecting retaining tabs (112) as well as at least one fixing portion (130) for fixing an airbag module (12) to a vehicle. For inserting the airbag package (14) into the wrapping (20) an intermediate cover made of a coherent piece of fabric is used into which the airbag package (14) is wrapped along with the inflator (18). The subassembly consisting of the intermediate cover, the airbag package (14) and the inflator (18) is inserted into the wrapping (20). Subsequently, the intermediate cover is removed from between the wrapping (20) and the airbag package (14) again.
