    • A stored gas inflator (10) comprising a pressure vessel (12) for storing a pressurized medium therein. The pressure vessel (12) has a wall (14) defining an interior of the vessel. A gas flow conduit (26) extends through the interior of the pressure vessel (12). The conduit (26) has a first portion extending from the interior of the vessel (12) through a first portion of the wall (14) to an exterior of the vessel, and a second portion extending from the interior of the vessel through a second portion of the wall (14) to the exterior of the vessel. Rupturable barriers (40) are formed along a portion of the conduit (26) that extends through the interior of the vessel, for separating an interior of the conduit (26) from the interior of the pressure vessel (12) prior to activation of the inflator (10). The barriers (40) are rupturable upon activation of the inflator (10) to enable fluid communication between the interior of the conduit (26) and the interior of the pressure vessel (12). This permits the pressurized inflation medium to flow from the pressure vessel (12) into the conduit (26) and out of the conduit in opposing directions into one or more associated airbag(s) or other inflatable element(s). Use of multiple gas flow paths from the inflator (10) permits a greater quantity of gas to flow relatively rapidly from the inflator (10).
    • 一种储存气体充气器(10),包括用于在其中储存加压介质的压力容器(12)。 压力容器(12)具有限定容器内部的壁(14)。 气流导管(26)延伸穿过压力容器(12)的内部。 管道(26)具有从容器(12)的内部延伸通过壁(14)的第一部分到容器的外部的第一部分,以及从容器的内部延伸穿过第二部分的第二部分 壁(14)的一部分到容器的外部。 沿着导管(26)的延伸穿过容器内部的部分形成可破裂的障碍物(40),用于在导管(26)的内部从压力容器(12)的内部分离内部 充气机(10)。 在激活充气器(10)时,障碍物(40)是可破裂的,以使导管(26)的内部和压力容器(12)的内部之间能够流体连通。 这允许加压的膨胀介质从压力容器(12)流入导管(26)并且在相反方向上从管道中流出到一个或多个相关联的气囊或其它可充气元件中。 使用来自充气机(10)的多个气体流动路径允许更大量的气体从充气机(10)相对快速地流动。
