摘要： An inflator for an air-bag comprises at least one gas bottle (1, 2) containing pressurised gas. The gas bottle is sealed by a rupturable foil (9). There is a support member (15) engaging the rupturable foil to maintain it in an unruptured state. The support member (15) is retained in an initial position by a part (23) of a piston element (20) which directly engages the support member (15). The piston element (20) is associated with a squib (11) to drive the piston element from an initial position to a release position in which the piston element no longer engages the support member (15). This permits the support member (15) to move to a position in which the foil (9) will rupture to permit gas to escape from the bottle. The preferred embodiment has two gas bottles each sealed by a respective foil each maintained by a support member which directly engages a single piston member.

摘要翻译： 一种用于气囊的充气机包括至少一个容纳加压气体的气瓶（1,2）。 气瓶由可破裂的箔片（9）密封。 有一个支撑件（15）与可破裂的金属薄片接合，以保持其未破裂状态。 支撑构件（15）通过直接接合支撑构件（15）的活塞元件（20）的一部分（23）保持在初始位置。 活塞元件（20）与引爆管（11）相关联以将活塞元件从初始位置驱动到释放位置，在该释放位置中，活塞元件不再接合支撑构件（15）。 这允许支撑构件（15）移动到箔（9）将破裂的位置，以允许气体从瓶中逸出。 优选实施例具有两个气瓶，每个气瓶都由各自的箔片密封，每个箔片由直接接合单个活塞构件的支撑构件维持。
