The invention relates to an assembly (20) consisting of an elongated gas generator (10) having an outer housing (14) with outflow openings (18) distributed in a circumferential direction (U), defining an outflow region (16) and an outflow direction, and a clip-shaped diffuser (22) surrounding the outflow region (16), in which assembly the diffuser (22) has a central receiving opening (24), the outer housing (14) protrudes into the receiving opening in such a way that the diffuser (22) surrounds an axial section of the outer housing (14), which axial section comprises the outflow region (16), in the circumferential sense. At least one contact surface (34) and at least one gas guide surface (30) are provided on an inner side of the diffuser (22) that delimits the receiving opening (24), the contact surface (34) directly contacting an outer housing (14) of the gas generator (10) and the gas guide surface (30) being radially spaced apart from the outer housing (14) to form at least one collecting chamber (32). The gas flowing out of the outflow region (16) flows into the at least one collection chamber. The collection chamber (32) opens into at least one outlet opening (36) through which the gas exits the diffuser (22) in an outlet direction (RD) transverse to the outflow direction from the gas generator (10).

    一种组件(20),组件由长形的气体发生器(10)和卡箍形的扩散器(22)构成,气体发生器具有外壳体(14),外壳体具有在周向(U)上分布的流出开口(18),流出开口限定流出区域(16)和流出方向,扩散器(22)包围流出区域(16),在组件中,扩散器(22)具有中央的接纳开口(24),外壳体(14)伸入到接纳开口中,使得扩散器(22)在周向意义上包围外壳体(14)的包括流出区域(16)的轴向区段。在扩散器(22)的、限定接纳开口(24)的内侧面上设置有至少一个贴靠面(34)和至少一个气体引导面(30),其中贴靠面(34)直接贴靠气体发生器(10)的外壳体(14),并且气体引导面(30)在径向上与外壳体(14)间隔开以形成至少一个收集腔室(32),从流出区域(16)流出的气体流入到至少一个收集腔室中。收集腔室(32)通入至少一个出口开口(36),气体通过该出口开口沿横向于从气体发生器(10)的流出方向的出口方向(RD)离开扩散器(22)。
