    • The invention relates to gas generators intended in particular for use in passive restraint systems and including an extruded section. Previous gas generators, in particular pipe gas generators, consist of a number of cylindrical housing sections which when assembled form a combustion and filter chamber. In the gas generators as per the present invention, the combustion and filter chamber consists of a single housing section which is closed off only at the open ends with covers. A housing of this type, produced by an extrusion process, can also have several combustion chambers. The invention greatly simplifies the construction of gas generators by reducing the number of housing parts. Further advantageous refinements allow the output of the gas generator to be matched to demand and the filtering and cooling to be optimised.
    • 本发明涉及特别用于被动约束系统并包括挤压部分的气体发生器。 以前的气体发生器,特别是管道气体发生器,由多个圆柱形壳体部分组成,当组装时形成燃烧室和过滤室。 在根据本发明的气体发生器中,燃烧室和过滤室由单个壳体部分组成,该壳体部分仅在具有盖的开口端封闭。 通过挤压工艺生产的这种类型的壳体也可以具有多个燃烧室。 通过减少壳体部件的数量,本发明极大地简化了气体发生器的构造。 进一步有利的改进允许气体发生器的输出与需求匹配,并且过滤和冷却被优化。
