Abstract: An airbag inflator assembly includes a cylindrical housing and internal components disposed in the cylindrical housing. The internal components include an initiator assembly, a generant, an internal nozzle, and a canister downstream of the internal nozzle. A center vent is secured to a downstream end of the cylindrical housing and includes a central passageway adjacent the canister for products of combustion and an exit passage that directs the products of combustion out of the assembly. The internal components and the center vent define a tortuous path for the products of combustion.

Abstract: An airbag inflator assembly includes a cylindrical housing, an initiator assembly secured in an upstream end of the cylindrical housing, and a generant disposed in the cylindrical housing adjacent the initiator assembly. Internal components define a tortuous path for products of combustion and define a plurality of debris collection areas. A rupture disk assembly is secured over an exit aperture, and a diffuser region downstream of the rupture disk assembly includes an output opening through which the products of combustion are vented into the airbag.

Abstract: An airbag inflator includes a pressure vessel with a bottom portion, a top portion and a center structure connecting the bottom portion and the top portion. The top portion includes an exit orifice that is closed with a rupturable membrane. An energetics cover attached to the center structure houses a pyrotechnic material, and a diverter is attached to the top portion. The pressure vessel, the energetics cover and the diverter define a gas flow path from inside the energetics cover toward the bottom portion of the pressure vessel, the gas flow path turning at least a first 180 degrees toward the top portion of the pressure vessel and between the energetics cover and the pressure vessel. The longer gas flow path allows time for multi-perforation grain slivers to burn up before exiting the inflator, thereby reducing the amount of particulate exiting the inflator.
