Airbag module for motor vehicles

An airbag module having a base element and a gas generator, the airbag module comprising:

• a coupling element for unreleasably connecting the gas generator to the base element;
• wherein the coupling element comprises contact regions having a large wall thickness and scaling regions with relatively small wall thickness disposed between the contact regions, wherein the coupling element and the gas generator mutually overlap in the axial direction with respect to a longitudinal module axis.

An airbag module for motor vehicles having 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, wherein the gas generator and the base element are combined to form an assembly serving as a vibration absorber and are unreleasably connected to one another by at least one elastic vibration damping coupling element via which the gas generator is supported over its area at the base element wherein the coupling element has reinforcement regions distributed in the circumferential direction in which the wall thickness of the coupling element is enlarged in comparison with regions disposed between the reinforcement regions in particular in the region of an upper and of a lower annular section.

An airbag module having a base element and a gas generator, the airbag module comprising:

• a coupling element for unreleasably connecting the gas generator to the base element;
• wherein the coupling element comprises contact regions having a large wall thickness and sealing regions with relatively small wall thickness disposed between the contact regions, wherein the gas generator has a collar for support at the coupling element which is preferably formed at least approximately in a U-shape in cross-section.

An airbag module having a base element and a gas generator, the airbag module comprising:

• a coupling element for releasably connecting the gas generator to the base element;
• wherein the coupling element comprises contact regions having a large wall thickness and sealing regions with relatively small wall thickness disposed between the contact regions, wherein the gas generator has an outer contour which is radially projecting or protruding and is connected to the coupling element.

An airbag module having a base element and a gas generator, the airbag module comprising:
