气体发生器技术领域本发明涉及一种气体发生器，其具有至少两个由燃烧室壁（15,17,18）限制的填充燃烧室（3,5）的推进剂填料（7,9）。 燃烧室壁（15,17）具有流出开口（19,21），所述流出开口在非激活状态下通过至少一个应用膜（27,29）而关闭。 在膜片（27，29）的边缘（41，43）的气体发生器的特征在于，具有一个附加的紧固装置或保护装置被至少部分设置，所述一个边缘侧的释放膜（27，29）（在燃烧室壁15，19的 ）阻止。

The invention relates to a gas generator having at least two with propellant charges (7, 9) filled combustion chambers (3, 5) which are delimited by combustion chamber walls (15, 17, 18). The combustion chamber walls (15, 17) have outlet openings (19, 21) which are closed in the non-activated state by at least one applied membrane (27, 29). The gas generator is characterized in that on the edge (41, 43) of the diaphragm (27, 29) at least in sections, an additional fastening means or a protective device is provided, the one edge-side releasing the membrane (27, 29) of the combustion chamber wall (15, 19 ) prevented.
