    • An air bag module includes an inflator and an air bag for inflation. The air bag includes retainer bars for attachment of the air bag to the housing. The module further includes an axially elongated, open-ended, generally cylindrical extruded housing having a circular-shaped cross section defined by a single cylindrical wall having an internal wall surface and an external wall surface. The housing includes integrally extruded air bag channels directly disposed on the external wall surface. The integrally extruded air bag channels axially receive the retainer bars of the air bag therein for attachment of the air bag to the housing such that the cylindrical wall and the air bag channels form a generally cylindrical-shaped housing which is lightweight and compact. Preferably, the module includes exactly two integrally formed channels directly disposed on the housing and a cover having axially extending enlarged portions thereon. The enlarged portions are preferably hollow and sized and shaped for receiving the retainer bars and enlarged portions therein. Thus, exactly two channels on the housing advantageously mount both the air bag and the cover to the housing.
    • 气囊模块包括充气机和用于充气的气囊。 气囊包括用于将气囊附接到壳体的保持杆。 模块还包括轴向细长的,开口的,大致圆柱形的挤出壳体,其具有由具有内壁表面和外壁表面的单个圆柱形壁限定的圆形横截面。 壳体包括直接设置在外壁表面上的整体挤出的气囊通道。 整体挤压的气囊通道在其中轴向地容纳气囊的保持杆,用于将气囊附接到壳体,使得圆柱形壁和气囊通道形成大体圆柱形的外壳,其轻便且紧凑。 优选地,模块包括直接设置在壳体上的两个整体形成的通道和在其上具有轴向延伸的扩大部分的盖。 扩大部分优选是中空的,并且其尺寸和形状用于容纳保持杆和其中的扩大部分。 因此,壳体上的正好两个通道有利地将气囊和盖子安装到壳体上。
