First Claim
Patent Images
1. A hybrid airbag inflator, comprising:
- a housing defining an interior, an exit port in said housing, said port accessing said interior, said interior being divided into first and second chambers, said second chamber having a vent port for directing heating gas from said second chamber in a longitudinal direction;
a pressurized inert gas stored in said first chamber;
a heating material stored in said second chamber to create said heating gas;
a gas impermeable member mounted in longitudinally spaced, opposed relation to said vent port, to thereby force radial flow of said heating gas;
a skirt having an upper end at least in proximity to said member, and a lower end extending toward said vent port, said skirt having a periphery encompassing at least said vent port to thereby block at least a substantial portion of said radial flow, and force reverse longitudinal flow of said heating gas subsequent to impingement upon said member.
