A dual flow inflator for airbags is disclosed, together with related manufacturing, installation, and deployment methods. The inflator may have a gas chamber with a first end with a first exit orifice and a second end with a second exit orifice. The exit orifices may be directed into inlet ports of an inflatable curtain so that inflation gases exit the inflator through the exit orifices and enter directly into the inflatable curtain. The exit orifices may provide axial gas flows in opposite directions so that each gas flow neutralizes the thrust of the other. The exit orifices may comprise frangible structures such as burst discs, scored surfaces, and compression closures. If desired, pistons may be utilized to ensure that the exit orifices are completely and simultaneously opened. Furthermore, the gas chamber may comprise a variety of configurations, including a unitary, one-piece structure, a multi-part structure with vessels attached to a tubular or spherical bulkhead, or a generally spherical shape.

Systems for use in leak detection and methods for leak detection are provided wherein a radioactive trace material is externally applied to a wall of a chamber which contains a fluid at a relatively high internal pressure.
摘要:
An inflatable curtain module is disclosed, where the inflatable curtain module has an inflator, and an inflatable curtain. The inflator may have a biaxial flow providing a gas input into two separate inflatable cushions. The cushions may be different sizes or volumes. Alternatively, other inflatable curtain modules may incorporate multiple inflators and multiple cushions to create an inflatable curtain module. The multiple inflators can be employed to provide two gas inputs into a single inflatable cushion. An inflatable curtain module may also be created from a number of generically sized cushions and inflators that are assembled into an inflatable curtain module for a wide range of vehicles.
摘要:
Inflation apparatuses are provided employing an elongated enclosed housing which contains a non-gaseous, fluid form of gas generant material. The housing can desirably be sufficiently flexible to permit the inflator device to be desirably shaped such as to facilitate the specific placement and location thereof within the interior of a vehicle. Also, provided are associated methods of gas production.
摘要:
A method for introducing a radioactive leak trace material into an apparatus for inflating an inflatable device is disclosed in which a mixture containing a preselected quantity of the radioactive leak trace material and a quantity of at least one gas source material, which upon initiation results in an inflation fluid used to inflate the device, are loaded into a chamber of the apparatus.
摘要:
A dual stage inflater for providing an extended flow of inflation gas to an airbag or inflatable curtain is disclosed. The inflator includes a first gas chamber having an exit orifice, the exit orifice having an open configuration and a closed configuration. Additionally, the inflator has a second gas chamber in gaseous communication with the first gas chamber. The first and second gas chambers are separated by a flow restrictor positioned between them. This restrictor controls the flow of gas out of the second gas chamber. The inflator includes an initiator in communication with the interior of one of the gas chambers that is configured to selectively initiate a flow of gas through the exit orifice of the first gas chamber. The exit orifice of the inflator may be disposed within an inlet port of an inflatable curtain to cause inflation gases exiting the inflator through the exit orifices to enter directly into the airbag or inflatable curtain.
摘要:
An airbag inflator having two individual sections coupled together by a connection member is disclosed. The vessel may be configured to have different airbag inflation characteristics. The sections may have different gas generants, volumes, and orifice sizes. The inflator may also include modular components. Various vessels having different inflation characteristics may be attached to a connection member. The use of modular components allows multiple inflator configurations to be created from a smaller number of components.
摘要:
An inflator assembly for an airbag safety system that comprises a container having a chamber configured to hold pressurized gases, an igniting assembly for producing exit gases and a diffusing assembly to vent the exit gases. The container is provided with an end closure that is composed of a material having a substantial silicon content. The diffusing assembly includes a diffuser cap and a burst disk. The diffuser cap has a number of apertures formed therein that allow the exit gases to be released when the burst disk ruptures. The igniting assembly is configured such that it may be coupled to the end closure and capable of withstanding a heat treatment process that bonds the igniting assembly, end closure and container together to form a one-piece structure.
