Abstract
A diffuser for uniformly diffusing inflation gas from an elongated inflator having inflation exhaust ports at only one end into an airbag cushion. The diffuser having a longitudinal length extending between opposing first and second diffuser ends. A first end section extends from the first diffuser end, is positionable over the inflation exhaust ports of the inflator and defines at least one diffuser vent opening. An intermediate section extends from the first end section and defines a plurality of diffuser vent openings equal or progressively larger further from the first end section. A second end section extends from the intermediate section to the second diffuser end and defines a single diffuser vent opening. Each of the plurality of diffuser vent openings of the intermediate section is equal or larger than the at least one diffuser vent opening of the first end section and equal or smaller than the single diffuser vent opening of the second end section. All of the diffuser vent openings form a total diffuser vent area of the diffuser. The first end section has a diffuser vent area equal to between about four and about ten percent of the total diffuser vent area, while the intermediate section has a diffuser vent area equal to between about thirty and about fifty-six percent of the total diffuser vent area, and the second end section has a diffuser vent area equal to between about forty and about sixty percent of the total diffuser vent area.
