Abstract
An airbag, or inflatable curtain airbag assembly, can include one or more chambers and vents. The vents can be in fluid communication with one or more of the chambers. The vents can be configured to delay passage of inflation gas from an interior of the airbag into an interior chamber or to an exterior of the airbag upon deployment of the airbag. The vents can also be configured to transition from a closed configuration to an open configuration when an internal pressure of the airbag reaches a predetermined value.
