摘要： A hybrid inflator for a vehicle passenger restraint system comprises a center tie having upper and lower ends, and a curved, continuous vessel wall secured to the upper and lower ends of and surrounding the center tie to define a pressure chamber storing inert compressed gas. The center tie defines a combustion chamber extending from the lower end thereof, the combustion chamber receiving pyrotechnic gaseous heat source material and a squib for igniting it. The center tie further defines a directional inlet port extending from the combustion chamber into the pressure chamber and a rupturable diaphragm seals the inlet port until ignition of the pyrotechnic generant. The center tie also defines a directional outlet vent extending from the pressure chamber adjacent the upper end of the center tie, the directional outlet vent being oriented substantially opposed the inlet port. The outlet vent is part of an outlet passage from the pressure chamber through the upper end of the center tie, including an orifice cavity and outlet orifice, oriented to provide further turns in the gas flow path. A rupturable diaphragm seals the outlet passage until ignition of the gas generant. A diffuser provides an additional change of direction of the outlet path.

摘要： An air bag system is provided for use in a motor vehicle. The air bag system includes at least one air bag module. A multiple level gas generation source is coupled to the air bag module for generating a selected gas generation level applied to the air bag module. An electronic control unit controls the operation of multiple level gas generation source. At least one temperature sensor is coupled to the electronic control unit for sensing ambient temperature. At least one seat belt sensor is coupled to the electronic control unit for sensing seat belt usage. An acceleration sensor is coupled to the electronic control unit for sensing deceleration during a crash. The electronic control unit is responsive to a combination of sensed inputs from the temperature sensor, the seat belt sensor and the acceleration sensor for determining both an optimum gas generation level and inflation sequence times for controlling the multiple level gas generation source.

摘要： Featured for use in the reaction canister of an inflatable restraint system is a continuous circumference diffuser tube. The diffuser tube may be a one-piece, two-piece or clamshell type all of which functionally are the same although the clamshell type is more versatile. The diffuser tube provides for the attachment of brackets for installation of the reaction canister in the instrument panel of a vehicle, provides a secure reliable attachment for the inflatable bag or protective cushion, and a secure installation of the inflator. The diffuser tube completely encloses the inflator and allows a last operation of assembly thereof.

摘要： An inflator capable of directing inflation gas into the cushion of an airbag module is thrust neutral during shipping, handling and installation. The inflator's thrust-neutral feature can be rendered inoperable for use with the airbag module. A thrust-balancing portion of the inflator has a circumferentially continuous sidewall that encloses an elongated passageway and has a proximal end configured to receive inflation gas from the inflator and a distal end configured to release a primary portion of the inflation gas into the cushion. In the event of unintended discharge during shipping or handling, an elongated secondary discharge aperture formed through the sidewall releases to the exterior of the thrust-balancing portion a secondary portion of the inflation gas that imposes thrust on the inflator directed oppositely from thrust imposed by release of the primary portion of the inflation gas stabilizing the inflator during shipping, handling and installation. The secondary discharge aperture includes a nonlinear slot formed through the sidewall partially circumscribing a deflection vane that tends to pivot outwardly of the sidewall in response to inflation gas inside the passageway, directing the secondary portion of the inflation gas away from the distal end of the sidewall.

摘要： A new type of airbag inflator that may be used in an airbag system is disclosed. The inflator will generally include a housing and two initiators. Accordingly, the inflator is a “dual-stage” inflator. The two stages are disposed within the housing. The second initiator is disposed within a second stage generant cup. A cap is also used to engage the second stage cup. The cap maintains seated engagement with the second stage cup, even during deployment of the second stage. The second stage will also include one or more perforations, which constitute openings through which gas may flow. When the second initiator is in the unactuated state, these perforations will be isolated from the generant by the cap. Actuation of the second initiator unseals the one or more perforations but does not unseat the cap from the cup, due to constraints put in place to prevent such unseating.

摘要： A new type of inflator that may be used to inflate an airbag is disclosed. The inflator will have a longitudinal axis, a first chamber, and a filter. The filter may be positioned outside of the first chamber. A first quantity of gas generant is positioned within the first chamber. A first strainer having a plurality of gas flow holes is also positioned within the first chamber. The first quantity of gas generant is located exterior of the strainer. Upon combustion of the first quantity of gas generant produces a first quantity of gas that flows towards the longitudinal axis while passing through the gas flow holes, enters the filter, and then flows away from the longitudinal axis while passing through the filter.

摘要： Disclosed are embodiments of apparatus, methods, and systems for cutting one or more tethers connected with an airbag cushion and simultaneously, or sequentially, closing one or more vent openings. In one embodiment, an airbag module is provided that includes a tether opening and at least one vent opening. The tether may extend through the tether opening adjacent to a cutter. The cutter may be configured to cut the tether upon deployment of an actuator. A vent door configured to block the vent opening(s) upon deployment of the actuator may also be provided. This embodiment may therefore provided for simultaneous, or sequential, cutting of the tether and closing of the vent opening(s) with a single actuator.
