Abstract:
1. A pyrotechnic inflator assembly containing a quantity of pyrotechnic material and having an initiator that upon actuation initiates reaction of the pyrotechnic material, the assembly comprising: a shell member having an open end, the shell member including a plurality of flow control features for controlling flow of product gas from the shell member; an end cap joinable with the shell member to at least in part enclose the open end of the shell member to form a subassembly, the subassembly containing the quantity of pyrotechnic material and at least in part defining a combustion chamber wherein at least a portion of the quantity of pyrotechnic material is reactable to form product gas for inflation of an associated airbag cushion and to generate pressure within the combustion chamber; and an overwrap about at least a portion of the subassembly to form a pyrotechnic inflator assembly that withstands the pressure generated within the combustion chamber upon reaction of the pyrotechnic material, the overwrap comprising a composite of fibers and a resin matrix system.
