The invention relates to an airbag module for motor vehicles comprising a housing for an inflatable airbag and a gas generator which is connected to a base element fixed to the module in the assembled state, with the gas generator and the base element being combined to form an assembly serving as a vibration absorber and being unreleasably connected to one another by at least one elastic and/or vibration damping coupling element via which the gas generator is supported over its area at the base element.

Airbag module for motor vehicles

A air bag module comprises an inflator, a unitary polymeric housing, and an air bag retainer of the same or similar material. The housing has integral walls forming an inflator chamber which include an inflator mounting stud aperture, a plurality of integral supports for the inflator, an integral peripheral rim forming an airbag chamber, and an integral upper wall having inflator gas diffuser apertures. An inflator stud fastener secures the inflator to the housing. The retainer and housing have integral cooperating fasteners for securing the retainer to the housing. A polymeric cover closes the retainer and confines the attached air bag. The housing and retainer are formed of the same recyclable material such that the air bag assembly can be recycled by simply removing only the stud fastener and the inflator. Several embodiments of the housing, retainer and fasteners are disclosed. In one embodiment, an inflator gas diffuser that is integral with the housing.

Recyclable airbag module housing

A housing ( ) is provided for a folded together inflatable airbag and a holder element ( ) which can be locked at the housing, with the housing and the holder element bounding a reception region for a gas generator ( ) in the locked state. In addition to an airbag and a gas generator, with the housing and the holder element, only two components are required in accordance with the invention, through which the manufacture may be simplified and manufacturing cost reductions may occur. For the assembly of the airbag module, the gas generator ( ) is first arranged either at the housing ( ) or at the holder element ( ) and then the holder element is locked at the housing. The gas generator ( ) is then already located in its final position in the airbag module. Through this the subsequent attachment of the folded together airbag in the housing is simplified since more than two parts which are to be connected together need never be brought into the correct relative position.

Airbag module

An airbag module for motor vehicles includes a housing for a folded together inflatable airbag and a holder element that can be locked at the housing. The holder element has at least one locking section, which in the locked state extends along the housing wall and latches with a holder section of the housing at its side which faces away from the housing wall.
