Abstract
A hybrid inflator, suitable for use on the driver side. The inflator includes a disk-shaped housing. Within the housing there is a first chamber for housing a stored gas charge. The housing also includes second chamber housing an initiator and a heating charge. The first chamber containing the stored gas includes a filter and various obstacles to force the hot gas from the second chamber to fully mix with the cool stored gas.
Claims15
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.
