Abstract
An inflatable side airbag has an inflatable duct for the delivery of inflation gas. The inflatable duct of the inflatable side airbag provides for rapid deployment of a multi-chamber air bag while controlling the rate of inflation and the relative pressure of the chambers. The inflatable duct allows a single inflator to inflate a high pressure pelvis chamber and a lower pressure thorax chamber while preventing fluid communication between the two chambers upon completion of inflation.
