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.
Claims19
An airbag inflator assembly comprising:
- a cylindrical housing;
- an initiator assembly secured in an upstream end of the cylindrical housing;
- a generant disposed in the cylindrical housing adjacent the initiator assembly;
- an internal nozzle through which products of combustion flow, the internal nozzle engaging an inside wall of the cylindrical housing;
- a canister disposed in the cylindrical housing downstream of the internal nozzle, wherein the internal nozzle tapers toward a nozzle opening and is configured to direct the products of combustion into the canister, a downstream end of the canister being closed, and the canister including radial orifices adjacent an upstream end, wherein an outside diameter of the canister is spaced from the inside wall of the cylindrical housing thereby defining an annular passageway, and wherein the internal nozzle and the canister define a debris collection area adjacent the radial orifices of the canister;
- and
- a center vent secured to a downstream end of the cylindrical housing, the center vent including a central passageway adjacent the canister for the products of combustion and an exit passage that directs the products of combustion out of the assembly.
An airbag inflator assembly comprising:

- internal components disposed in the cylindrical housing including an initiator assembly, a generant, an internal nozzle that tapers toward a nozzle opening, and a canister downstream of the internal nozzle, wherein a downstream end of the canister is closed, and wherein the internal nozzle and the canister define a debris collection area adjacent an upstream end of the canister;
- and
- a center vent secured to a downstream end of the cylindrical housing, the center vent including a central passageway adjacent the canister for products of combustion and an exit passage that directs the products of combustion out of the assembly,
- wherein the internal components and the center vent define a tortuous path for the products of combustion with at least six turns.
