    • An inflator device for inflating an inflatable cushion of an inflatable cushion restraint system. The inflator device includes a supply of gas generant material disposed within a sealed chamber, and an initiator device in reaction initiation combination with the supply of gas generant material. A venting orifice connects the chamber to the surrounding ambient environment, and a rupturable seal seals the venting orifice. Upon reaction initiation of the gas generant material to produce inflation gas, the rupturable seal ruptures to vent the chamber to the ambient environment. A valve assembly can be disposed adjacent the venting orifice. A moveable valve piston, in combination with an actuator device, can block the venting orifice as needed to close the venting orifice and stop inflation gas venting. An optional tether release mechanism can be used in combination with the valve assembly to release a cushion tether upon closing of the venting orifice.
    • 一种充气装置,用于充气可充气缓冲系统的充气垫。 充气装置包括设置在密封室内的气体发生剂供应源,以及与气体发生剂材料供给反应引发组合的引发装置。 排气孔将腔室连接到周围的环境环境,并且可破裂的密封件密封排气孔。 当产生气体发生剂材料的反应开始产生膨胀气体时,可破裂密封件破裂以将该腔室排放到周围环境。 阀组件可邻近排气口设置。 可移动的阀活塞与致动器装置组合可根据需要阻塞通气孔以关闭排气孔并阻止膨胀气体排放。 可选的系链释放机构可以与阀组件一起使用,以在关闭排气孔时释放衬垫系绳。
