摘要： A multi-level output inflator for air bags or the like, comprising a center bulkhead, a primary gas generating unit connected at its inner end to one side of the bulkhead, and a secondary gas generating unit connected at its inner end to the opposite side of the bulkhead. The primary gas generating unit comprises a primary pressure vessel disposed adjacent to the bulkhead and in communication therewith, with an inert gas under pressure in the primary pressure vessel. The secondary gas generating unit comprises a secondary pressure vessel disposed adjacent to the bulkhead and in communication therewith, with an inert gas under pressure in the secondary pressure vessel. The bulkhead comprises a first opening therein in communication with the primary pressure vessel and a primary outlet port in communication with the first opening. A second opening is provided in the bulkhead with is in communication with the secondary pressure vessel and a secondary outlet port. A primary burst disc is disposed between the first opening of the bulkhead and the primary pressure vessel, and a secondary burst disc is provided between the second bulkhead opening and the secondary pressure vessel. Upon the ignition of the gas generating charge of one of the gas generating units, the gas therein is further pressurized to rupture the adjacent burst disc and effect the flow of the pressurized gas to the adjacent bulkhead opening and outlet port to the air bag for inflation thereof.

摘要： A multi-level inflator for an air bag or other safety restraint device, comprising an elongated pressure vessel having a primary gas generating portion with a first open end and a gas storage portion with a second open end. The primary gas generating portion has a primary initiator and primary gas generating energetics disposed therein, the initiator being mounted on an igniter body secured to and closing the pressure vessel at the first open end thereof. A pressure vessel closure is secured to the second end of the pressure vessel, the closure having an aperture therethrough and a primary rupture disk secured thereto to close the aperture. The gas storage portion has an inert gas therein under a predetermined pressure. A secondary inflator of the all-pyrotechnic type is secured to the pressure vessel and closure at the second end thereof. The secondary inflator comprises a secondary housing having a secondary initiator and secondary gas generating energetics disposed therein. A choke plate having an opening therethrough is positioned between the secondary energetics and the pressure vessel closure. A secondary rupture disk is secured tot he choke plate to close the opening therein.
