The invention relates to an airbag module (10) having an airbag (12), an elongated gas generator (14) having a housing (18) with outflow openings (20) distributed over a perimeter (U) which delimit an outflow region (22), and a diffuser (16), the outflow region (22) of the gas generator (14) being surrounded by the diffuser (16), the diffuser (16) has at least one contact surface (26, 26a) and at least two gas guide surfaces (28a, 28b) on the inner side of the diffuser (16) delimiting the receiving opening (24), the contact surface (26, 26a) directly resting on the housing (18) of the gas generator (14) and the gas guide surfaces (28a, 28b) being radially spaced from the housing (16) by forming at least one first collecting chamber (30a) and a second collecting chamber (30b), the diffuser (16) is arranged entirely in the inflatable interior volume of the airbag (12), the airbag (12) comprising at least a first airbag chamber (36a) and a second airbag chamber (36b) configured to be separated from each other, the gas flowing into the first collection chamber (30a) flowing into the first airbag chamber (36a) of the airbag (12) via a first discharge opening (32a), and the gas flowing into the second collection chamber (36b) flowing into the second collection chamber (36b) of the airbag (12) via a second discharge opening (32b). The gas flowing into the second collection chamber (30b) flows into a second airbag chamber (36b) of the airbag (12) via a second discharge opening (32b).

    本发明涉及气囊模块(10),该气囊模块具有气囊(12)、长形的气体发生器(14)和扩散器(16),气体发生器(14)具有外壳(18),该外壳具有分布在周界(U)上的流出开口(20),这些流出开口限定流出区域(22),气体发生器(14)的流出区域(22)被扩散器(16)包围,扩散器(16)在扩散器(16)的界定容纳开口(24)的内侧上具有至少一个贴靠面(26、26a)和至少两个导气面(28a、28b),贴靠面(26、26a)直接贴靠在气体发生器(14)的外壳(18)上并且导气面(28a、28b)通过构成至少一个第一收集室(30a)和第二收集室(30b)而与外壳(16)径向间隔开,扩散器(16)完全设置在气囊(12)的可充气内部体积中,气囊(12)包括至少一个第一气囊腔室(36a)和第二气囊腔室(36b),它们构造为彼此分离,流出到第一收集室(30a)中的气体经由第一排出开口(32a)流出到气囊(12)的第一气囊腔室(36a)中,流出到第二收集室(30b)中的气体经由第二排出开口(32b)流出到气囊(12)的第二气囊腔室(36b)中。
