摘要： An air bag module using a tubular inflator uses a different housing, retaining ring, cushion and inflator bracket than are currently used, with the appearance and function of the module not being changed but only the internal components. The inflator is placed in a slotted section of the module housing with the diffuser thereof protruding from the center through a hole in a raised portion of the module housing slotted section, which hole is sized closely to the size of the diffuser. The diffuser extends directly into the module at a 90.degree. angle to the plane surface of the housing. The retaining ring has raised portions in the center thereof to match the raised portion of the module housing, has holes in the raised portions, and has tabs which extend through holes in the cushion and the module housing. The module housing has tabs on the raised portion thereof which extend through holes in the cushion and retaining ring. The cushion uses a rectangular mounting so that the cushion can match the radius of the module housing in the raised portion which goes over the tubular inflator. The retaining bracket extends around the back side of the inflator to hold it in place and includes cover retaining brackets incorporated therein. Studs which hold the module together extend from the retaining ring through holes in the cushion, module housing, and retaining bracket.
摘要翻译：使用管状充气机的气囊模块使用与目前使用的不同的外壳，固定环，缓冲垫和充气机支架，模块的外观和功能不会改变，而只是内部组件。充气机被放置在模块壳体的开槽部分中，其扩散器通过模块壳体开槽部分的凸起部分中的孔从中心突出，该孔的尺寸与扩散器的尺寸相近。扩散器以与壳体的平面成90度的角度直接延伸到模块中。保持环在其中心具有凸起部分以匹配模块壳体的凸起部分，在凸起部分中具有孔，并且具有延伸穿过衬垫和模块壳体中的孔的突片。模块外壳在其凸起部分上具有延伸穿过缓冲垫和保持环中的孔的突片。垫子使用矩形安装件，使得衬垫可以匹配在管状充气机上方的凸起部分中的模块壳体的半径。保持支架围绕充气机的后侧延伸以将其保持在适当的位置并且包括并入其中的盖保持支架。将模块固定在一起的螺栓从保持环穿过垫子，模块外壳和固定支架中的孔延伸。

摘要： The invention facilitates fixedly attaching to vehicle steering wheels different or variously styled driver restraint modules, while incorporating common major module components. For example, three (3) different modules use the same major module components (reaction plate, inflator, and folded air bag) but utilize different brackets for steering wheel mounting and adaptation to the styling locations of selected ones of the variously styled driver module assemblies for horn blowing, speed control, etc. This makes it possbile to use more common production tooling, i.e., for cover attachment, bag folding, etc., thus enabling manufacturing cost reduction.
摘要翻译：本发明有助于固定地连接到车辆方向盘上不同或不同样式的驾驶员限制模块，同时结合常见的主要模块组件。例如，三（3）个不同模块使用相同的主要模块组件（反应板，充气机和折叠气囊），但是使用不同的支架进行方向盘安装并适应各种风格的驱动模块组件中所选择的样式位置用于吹喇叭，速度控制等。这使得可以使用更常用的生产工具，即，用于盖子附件，袋子折叠等，从而能够降低制造成本。

摘要： A new type of airbag inflator that may be used in an airbag system is disclosed. The inflator will generally include a housing and two initiators. Accordingly, the inflator is a “dual-stage” inflator. The two stages are disposed within the housing. The second initiator is disposed within a second stage generant cup. A cap is also used to engage the second stage cup. The cap maintains seated engagement with the second stage cup, even during deployment of the second stage. The second stage will also include one or more perforations, which constitute openings through which gas may flow. When the second initiator is in the unactuated state, these perforations will be isolated from the generant by the cap. Actuation of the second initiator unseals the one or more perforations but does not unseat the cap from the cup, due to constraints put in place to prevent such unseating.

摘要： An air bag module uses a tubular inflator that is mounted off center in the module with the diffuser lying in the plane of the bottom of the module housing. The housing and inflator retaining bracket combine to make a pocket which changes the direction of some of the gas produced by the inflator and allows all of the gas to flow up into the inflatable cushion. A different housing, retaining ring, cushion and inflator retaining bracket are used in the assemblage of the module than are employed in air bag modules of current production. The appearance and function of the module, however, is not changed to a purchaser of the automotive vehicle in which the module is installed, only the internal components of the module are changed.

摘要翻译：公开了一种可用于气囊系统的新型安全气囊充气机。充气机通常包括外壳和两个起动器。因此，充气机是“双级”充气机。两个阶段都设置在外壳内。第二起动器设置在第二级发生杯内。帽也用于接合第二级杯。即使在第二阶段的部署期间，盖子也保持与第二级杯子的就座接合。第二阶段还将包括一个或多个穿孔，其构成气体可流过的开口。当第二启动器处于未致动状态时，这些穿孔将通过盖与发生器隔离。由于施加了限制，防止这种脱落，第二起动器的致动器开启一个或多个穿孔，但是不会将盖从杯中脱离。

摘要： The present invention provides an airbag inflator assembled, in part, using ultrasonic welding. The inflator includes a housing adapted to receive an initiator assembly and an adaptor socket to connect the inflator to the electronic systems of the vehicle. The initiator and the adaptor socket are welded together at a point of interface through the housing of the inflator using an ultrasound welding process. Joint seals are provided that allow the production of a gas-tight seal upon completion of assembly of the airbag inflator.

摘要： A pyrotechnic inflator assembly including a shell member and an end cap joinable with the shell member to form a subassembly. The subassembly contains a quantity of pyrotechnic material and at least in part defines a combustion chamber wherein at least a portion of the quantity of pyrotechnic material is reactable to form product gas for inflation of an associated airbag cushion and to generate pressure therewithin. A diffuser assembly can be disposed adjacent an end of the shell member and includes flow control features for controlling flow of product gas from the inflator assembly. The inflator assembly further includes a composite overwrap about at least a portion of the subassembly and the diffuser assembly such that the pyrotechnic inflator assembly can withstand the pressure generated within the combustion chamber upon reaction of the pyrotechnic material. Corresponding methods of making a pyrotechnic inflator assembly are also provided.
