Abstract
A pyrotechnic inflator assembly including a shell member and an end cap joinable with the shell member to form a subassembly. The subassembly contains a quantity of pyrotechnic material and at least in part defines 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 therewithin. A diffuser assembly can be disposed adjacent an end of the shell member and includes flow control features for controlling flow of product gas from the inflator assembly. The inflator assembly further includes a composite overwrap about at least a portion of the subassembly and the diffuser assembly such that the pyrotechnic inflator assembly can withstand the pressure generated within the combustion chamber upon reaction of the pyrotechnic material. Corresponding methods of making a pyrotechnic inflator assembly are also provided.
