摘要： A driver-side air bag module is mounted to a steering wheel assembly mounting bracket having three mounting apertures. The module comprises a cover, an inflator and a base plate, which are assembled without using fasteners. The base plate has a plurality of arcuately-spaced mounting apertures and mounts three studs. The cover includes a plurality of mating flexible tangs having locking shoulders. The inflator has a peripheral mounting flange which includes three arcuately-spaced locking blades and a plurality of locking tabs projecting from its surface. The base plate has three mating openings each having an adjacent locking abutment. The studs are first staked to the base plate. The cover is assembled by inserting the tangs through the base plate mounting apertures so that the shoulders snap over to engage the base plate. The inflator locking blades are pushed through the base plate mating openings and twisted to pass them over the locking abutments. This traps the base plate between the blades and the mounting flange and abuts the locking tabs with the cover tangs, preventing their removal. Three inflator mounting flange slots receive the studs during assembly. The air bag module is installed by projecting the studs through the steering wheel assembly mounting bracket apertures, where the spring fingers snap into the stud grooves to prevent removal. The locking tangs, tabs and base plate apertures are unequally spaced, and the studs and apertures are unequally spaced to assure a predetermined orientation of the module when installed.
摘要翻译：驱动器侧气囊模块安装到具有三个安装孔的方向盘组件安装支架上。模块包括盖子，充气机和基板，它们在不使用紧固件的情况下被组装。基板具有多个弧形间隔开的安装孔并安装三个螺栓。盖包括具有锁定肩部的多个配合柔性柄脚。充气机具有周边安装凸缘，其包括三个弧形间隔的锁定刀片和从其表面突出的多个锁定突出部。基板具有三个配合开口，每个具有相邻的锁定支座。首先将螺柱固定在基板上。通过将脚部插入基板安装孔中来组装盖子，使得肩部卡扣以与基板接合。充气机锁定刀片被推动通过基板配合开口并且被扭转以将它们传递到锁定基座上。这将基板夹在叶片和安装法兰之间，并与盖板脚紧贴锁定突出部，防止其脱落。在组装过程中，三个充气机安装法兰槽接收螺柱。气囊模块通过将螺柱突出通过方向盘组件安装支架孔而安装，其中弹簧指状物卡入螺柱槽以防止移除。锁定柄脚，突片和底板孔不等间隔，并且螺柱和孔不等间隔，以确保在安装时模块的预定取向。

摘要： Two embodiments of an air bag module and method of assembly are disclosed. One air bag module includes a flat support plate and a cover confining an air bag. The cover confines the air bag and has a plurality of resilient latch hooks spaced about its periphery which snap over the edges of the support plate and engage adjacent latch surfaces. A locking plate has a locking tab located adjacent each latch hook when assembled to the support plate to prevent deflection of the latch hooks and maintain the latch hooks in engagement with the latch surfaces. The inflator is later secured to the support plate by rivets which also secure the air bag and locking plate to the support plate. Another air bag module includes an air bag, an inflator, an open rectangular retainer mounting the air bag, and an open top and bottom container receiving the retainer and mounting the inflator, and a cover. A plurality of resilient latch hooks on the cover snap over the walls of the retainer and into indentations formed on the periphery of the bottom of the retainer. The retainer is inserted into the top of the container and the camming flanges guide the latch hooks into engagement with the walls of the container which confine the latch hooks against deflection, thus securing the cover against separation. The inflator is later inserted into the bottom opening of the container and secured by a closure.
摘要翻译：公开了气囊模块的两个实施例和组装方法。一个气囊模块包括平坦的支撑板和限制气囊的盖子。盖子限制气囊并且具有围绕其周边间隔开的多个弹性闩钩，其卡扣在支撑板的边缘上并且接合相邻的闩锁表面。当组装到支撑板上时，锁定板具有邻近每个闩锁钩的锁定突出部，以防止闩锁钩的偏转并且将闩钩保持与闩锁表面接合。充气机随后通过铆钉固定到支撑板，铆钉也将气囊和锁定板固定到支撑板上。另一个气囊模块包括安全气囊，充气机，安装气囊的敞开的矩形保持架，以及容纳保持器和安装充气机的敞开的顶部和底部容器以及盖子。盖上的多个弹性锁钩卡扣在保持器的壁上并且形成在保持器的底部周边上的凹陷中。保持器插入容器的顶部，并且凸轮凸缘引导闩锁钩与容器的壁接合，从而将闩锁钩限制成偏转，从而固定盖子以免分离。充气机后来插入容器的底部开口并用闭合件固定。

摘要： A vehicle air bag module mounted on a vehicle steering column comprises a container containing an inflator and an air bag folded on top. The air bag has a fabric body, a gas inlet surrounding the inflator, and a crown located opposite the gas inlet. The outer ends of four tethers are equally spaced about the center of the crown and are sewn to it. The inner ends of the tethers are clamped to the casing of the inflator and held by frictional force. Upon inflation, the periphery of the air bag deploys to its full breadth as the tethers restrain deployment of the air bag center. After inflation pressure builds, the force exerted on the air bag crown overcomes the frictional force holding the tether inner ends, which will release, enabling the entire air bag to fully inflate. In a modification, the tethers are all sewn to the upper portion of the air bag crown to delay deployment of the upper part of the air bag until the lower part has deployed.
摘要翻译：安装在车辆转向柱上的车辆安全气囊模块包括容纳充气机和顶部折叠的气囊的容器。气囊具有织物主体，围绕充气器的气体入口以及与气体入口相对的冠部。四个系绳的外端在冠的中心周围等间隔并缝合到其上。系绳的内端被夹紧在充气机的外壳上并由摩擦力保持。在充气时，气囊的周边部分充分扩大，因为系绳限制了气囊中心的展开。在充气压力建立后，施加在气囊冠上的力克服了保持系绳内端的摩擦力，这将释放，使得整个气囊能够完全充气。在一个修改中，系绳都缝合到气囊冠的上部，以延迟气囊的上部的展开，直到下部展开。

摘要： An energy absorber adapted to be interposed between relatively movable rigid support and impact receiving elements and including a sheet metal plate of rectangular shape. The plate is provided with two asymmetric spaced U-shaped slots and a pair of spaced parallel slots to divide the plate into a continuous integral outer portion; an asymmetric pair of generally U-shape inner portions, the legs of which are integrally connected to the continuous outer portion by bridging portions; and a center portion of rectangular shape integrally connecting the bights of the inner portions. The outer portion is secured to one of the elements and the center portion is secured to the other by a rigid post. Upon impact loads applied to the impact receiving element, the U-shape inner portions fold relative to each other and the outer portion about the bridging portions and the center portion folds upon itself and relative to the U-shape inner portions to form the energy absorber into generally trapezoidal shape and absorb energy.
