    • An air bag module is provided for inflating an air bag cushion at variable rates in response to rapid deceleration of a motor vehicle. The air bag module includes an inflator for generating inflator gas to inflate an air bag cushion upon the sensing rapid deceleration of a vehicle. An annular cushion retainer is disposed about the inflator for directing gases from the inflator to the air bag cushion. The cushion retainer includes an annular cavity in fluid communication with the air bag cushion by a vent opening to selectively direct gas away from the air bag cushion during a reduced level of deployment. A controller generates an ignition signal to the inflator in response to velocity responsive sensors. In response to the ignition signals, the inflator releases an appropriate predetermined volume of gas into the air bag cushion. The level of deployment or inflation of the air bag cushion is dependent on the actuation of a slide actuator assembly arranged to selectively block the vent opening of the cushion retainer to restrict or block gas flow directed away from the air bag cushion to the exterior of the air bag module.
    • 提供一种安全气囊模块,用于响应于机动车辆的快速减速,以可变的速率对气囊垫进行充气。 气囊模块包括用于产生充气器气体的充气器,以在车辆的感测快速减速时使气囊垫膨胀。 围绕充气机设置环形缓冲保持器,用于将气体从充气器引导到气囊垫。 缓冲保持器包括通过排气口与气囊垫流体连通的环形空腔,以在降低的展开水平期间选择性地将气体从气囊缓冲器引导出来。 控制器响应于速度响应传感器而向充气机产生点火信号。 响应于点火信号,充气机将适当的预定体积的气体释放到气囊垫中。 气囊垫的展开或膨胀的程度取决于滑动致动器组件的致动,该滑动致动器组件被布置成选择性地阻塞缓冲保持器的通气开口,以限制或阻止远离气囊垫的气流朝向 气囊模块

    • This present invention provides variable deployment performance by controlling the quantity and fluid flow path of the inflator gas into or out of an air bag module according to the present invention. The air bag module includes a slide ring mechanism disposed about an inflator and adjacent at least a portion of a cushion retainer. The slide ring mechanism comprises an annular ring having openings formed therein, wherein during rotation of the slide mechanism, the openings of the annular ring align with openings formed in the cushion retainer to define a fluid flow path away from an air bag cushion for venting some of the inflator gas. Preferably, the annular ring is rotated by attaching a pair of tethers to the annular ring and to a rear surface of the air bag cushion. As the air bag cushion inflates and reaches a predetermined pressure, the tethers are pulled causing the slide ring to rotate so that the openings in the annular ring and cushion retainer align directing an amount of inflator gas away from the air bag cushion. The present invention thus provides a direct mechanical system for cushion pressure feedback to tailor the inflation.

    • An air bag module includes an air bag and an inflator being activatable to discharge inflator gas for inflating the air bag. The inflator has at least one discharge port through which inflator gas is discharged. A housing has a wall adjacent the discharge port of the inflator and includes at least one vent opening. The module also includes a movable member alignable with the vent opening. The movable member is movable relative to the vent opening for opening and closing the vent opening at a predetermined time during inflator activation to control the amount of inflator gas discharged into the air bag and the amount of inflator gas expelled out through the vent opening of the housing. A device is activatable during activation of the inflator to move the movable member relative to the vent opening at the predetermined time during inflator. activation.
