A high strength dual-swaged airbag inflator vessel comprising a high strength metal material, such as low carbon steel, has a swaged terminal end defining two distinct swaged portions. A reduction of diameter within one of the swaged portions is restricted to be less than or equal to about 30% and in certain variations, less than or equal to about 16% to minimize cold work strain hardening and to reduce loss of ductility. In certain aspects, a second swaged portion within the swaged terminal end has a length of less than or equal to about 10 mm. Methods for making such a dual-swaged airbag inflator vessel are likewise provided. Such dual swage designs have improved reliability and performance in high pressure inflator applications, as well as reduced manufacturing costs.

Double swage airbag inflator vessel and methods for manufacture thereof

An inflator for an airbag is provided. The inflator can include a housing that has a first end and a second end. The inflator can also include a gas generant disposed in the housing that defines a bore. The inflator can include an igniter coupled to the first end of the housing that can ignite the gas generant upon receipt of a signal. The inflator can further include a temporary closure coupled to the second end of the housing that can be opened to provide an exit out of the housing. The ignition of the igniter can generate a shockwave that passes through the bore to open the temporary closure.
