Abstract:
Airbag module having a gas bag, gas generator and a module cover having a tear-open area is arranged above the gas generator wherein the gas generator is mounted essentially coaxially in a diffuser which encloses the gas generator and is provided with outflow openings, and the diffuser extends in a side wall area at a distance from the gas generator, the side wall area thereby extends beyond the gas generator upwards towards the tear-open area of the module cover and encloses at least substantially the same cross-section as a side wall area adjacent the gas generator;wherein the diffuser has a stepped construction with a lower side wall area, an upper side wall area and a central side wall area which connects the upper wide wall area and the lower side wall area and which defines a step therebetween, wherein the lower side wall area extends a distance from the gas generator and beyond the gas generator towards the tear-open area of the module cover, the diffuser has in an upper side wall area a smaller cross-sectional surface than the gas generator and in this area the outflow openings are provided for the gases of the gas generator to discharge into the gas bag transversely to a longitudinal axis of the diffuser, and wherein the central side wall area is deformable relative to the upper side wall and the lower side wall.
