Abstract

An airbag module and method of mounting an airbag to the module. The module has an airbag, a gas generator, and a housing containing the airbag and the gas generator. The housing has a single-piece construction, including a container-shaped cover and a generator support foldably mounted to the cover. The airbag has a slot for inserting the gas generator, and a plurality of passages for passage of fasteners, which can be premounted to the gas generator. The slot forms two mount zones that can overlap. The airbag is folded into the cover or folded airbag can be placed into the cover. Thereafter, the gas generator is inserted into the airbag through the slot. The fasteners are inserted through the passages one at a time so that the mount zones overlap. The generator support is then folded over the cover, with the fasteners extending through the support via appropriate openings formed therethrough. The airbag module now can be seated and secured to a steering wheel using the fasteners and nuts.
