摘要： The present invention provides variable deployment performance by controlling the heat content of the inflator gas which exits an air bag sub-module, disposed in a module, into an air bag cushion. The air bag sub-module includes a sub-module housing which receives an inflator in a central cavity formed therein. The module housing includes low output module ports formed in the module housing and high output module ports. Heat sinking material is disposed within the sub-module housing between an outer wall of the sub-module housing and the inflator such that the heat sinking material surrounds the low output module ports. The air bag sub-module provides a first fluid flow path for the heated inflator gas to flow under high level deployment conditions and a second fluid flow path for the inflator gas to flow under reduced level deployment conditions. The first fluid flow path comprises a low resistance fluid flow path in which the heated inflator gas exits the inflator through the high output module ports. Little or no heated inflator gas will flow through the second fluid flow path, which comprises a high resistance fluid flow path, because in order for the inflator gas to flow according to the second fluid flow path, the inflator gas must pass through the high resistance heat sink material and the low output module ports. The heat content of the inflator gas is reduced by forcing the inflator gas to flow according to the second fluid flow path.
摘要翻译：本发明通过将离开设置在模块中的气囊子模块的充气器气体的热含量控制到气囊垫中来提供可变的部署性能。气囊子模块包括在其中形成的中心腔中容纳充气机的子模块壳体。模块外壳包括形成在模块外壳中的低输出模块端口和高输出模块端口。散热材料设置在子模块壳体内，在子模块壳体的外壁和充气机之间，使得散热材料围绕低输出模块端口。气囊子模块提供第一流体流动路径，用于加热的充气器气体在高水平的展开条件下流动，第二流体流动路径用于使充气器气体在降低的部署条件下流动。第一流体流动路径包括低阻力流体流动路径，其中加热的充气机气体通过高输出模块端口离开充气机。由于为了使充气机气体根据第二流体流动路径流动，充气机气体必须通过高阻力，所以很少或没有加热的充气机气体将流过包括高阻流体流路的第二流体流路，散热材料和低输出模块端口。通过迫使充气机气体根据第二流体流动路径流动来减少充气机气体的热量。

摘要： A variable output air bag inflator is presented wherein in one embodiment the inflator offers variable output and may be implemented with either pyrotechnic or hybrid inflators. The inflator offers full level deployment at a first end of the inflator unit and reduced level deployment at a second end. This is accomplished by providing two discrete paths for the inflator gas to flow during deployment of the air bag cushion. One path communicates with a first filter material or permits the hot inflation gas to directly exit the inflator without passing through a filter material. The other path communicates with a second filter material which absorbs heat from the inflator gas as it passes through the second filter material before exiting the inflator, wherein the second filter material has a heat sink capacity greater than the first filter material. The energy content and pressure of the inflator gas is therefore regulated by directing the inflator gas through the second filter material.
