Abstract
An inflation device for an airbag module, the inflation device comprising: a first chamber and a second chamber, the first chamber having a first volume of inflation gas and the second chamber having a second volume of inflation gas; a first inflation opening for allowing the first volume of inflation gas to pass therethrough and a first sealing member, the first sealing member sealing the first inflation opening; a second inflation opening for allowing the second volume of inflation gas to pass therethrough and a second sealing member, the second sealing member sealing the second inflation opening, the second inflation opening being substantially smaller than the first inflation opening; a conduit member for providing fluid communication with the first inflation opening and the second inflation opening; an initiator for removing a portion of the first sealing member from the first inflation opening; and a puncture device disposed within the conduit member, the puncture device being configured to remove a portion of the second sealing member when the portion of the first sealing member is removed from the first sealing opening, wherein the first volume of inflation gas glows from the first volume at a first flow rate and the second volume of inflation gas flows from the second volume at a second flow rate, the second flow rate being smaller than the first flow rate, wherein the second inflation gas flows from the second volume for a period of time longer than the first volume flows from the first volume.
