The present application relates to a gunpowder chamber for a hybrid gas generator, comprising a tube body (60) and a first (1) and a second (2) separating element. The first separating element has a through-opening (5) which forms an ignition channel for an ignition system (10). A first chamber (6) for accommodating gunpowder (4) is formed between the two separating elements. The second separating element has a peripheral portion (11) and a central portion (12) which is connected to the peripheral portion and which extends at least partially in a tapering manner in the axial direction of the tube body towards the first separating element. The central portion has a wall surrounding the longitudinal axis of the tube, the wall enclosing and defining a second chamber (7), a plurality of vent holes (13) being provided in the wall, the plurality of vent holes being configured such that the reaction gas is mixed with the compressed gas stored in the tube through the plurality of vent holes. The invention further relates to a hybrid gas generator and a safety airbag.

    本申请涉及一种用于混合式气体发生器的火药室,其包括管体(60)以及第一分隔元件(1)和第二分隔元件(2)。第一分隔元件具有通孔(5),该通孔形成用于点火系统(10)的点火通道。在两个分隔元件之间形成用于容纳火药(4)的第一腔室(6)。第二分隔元件具有外围部分(11)以及与外围部分连接的、在管体的轴向方向上朝第一分隔元件至少局部渐缩地延伸的中央部分(12)。所述中央部分具有围绕管体纵轴线的壁体,所述壁体包围限定第二腔室(7),在所述壁体中设置有多个排气孔(13),所述多个排气孔构造成,使得反应气体通过所述多个排气孔与在管体中存储的压缩气体混合。本申请还涉及一种混合式气体发生器以及一种安全气囊。
