    • The invention relates to a gas generator for an airbag (11) comprising a cartridge (3) containing a gas-generating charge of solid material (5) and a storage reservoir (9) containing a storage gas (10). To trigger gas production the charge of solid material (5) is ignited. The resulting gas pressure tears off the front face (13) of the cartridge (3) along a peripheral notch (6). A sliding element (7) connected to the front face (13) pierces a sealing element (8) of the storage reservoir (9). A guiding channel (23) in which the front face (13) is guided in the manner of a piston, opens into a flow zone (12). When the front face (13) has reached the flow zone (12), reaction gas flows around the front face (13) into openings (16) in the tube-shaped sliding element (7). The reactant gas then flows into the storage reservoir (9) where it is mixed with the remaining storage gas. Because the control for releasing the two gases depends entirely on the trajectory, the operating performance of the hybrid gas generator is exact and reproducible.
    • 一种用于气囊(11)的混合气体发生器包括药筒(3),其含有一个气体发生固体电荷(5),和一个储存罐(9)含有一个存储气体(10)。 用于触发固体电荷(5)被点燃。 随着气体压力的结果,所述端壁(13)从拉在一个周向槽(6)的盒(3)。 阿与连接到所述滑动件(7)与所述储存容器(9)的关闭元件(8)满足所述端壁(13)。 的导向通道(23),其中,所述端壁(13)被引导以活塞的方式,通入流动区(12)。 当端壁(13)已经达到了流动区(12),反应气体流至所述端壁(13)在管状滑动件(7)的开口(16)周围。 然后将反应气体流入储存箱(9),在那里与剩余存储气体混合。 由于该两种气体的释放的纯路径相关的控制,混合气体发生器的精确和可重复的性能得以实现。
