An airbag module for a motor vehicle includes an inflatable airbag cushion, an inflator, and a flow director. The inflatable airbag cushion includes one or more panels that form an inflatable portion. The inflator is configured to provide inflation gas for inflating the airbag cushion upon deployment. The flow director is configured to direct inflation gas into the inflatable portion. The inflatable portion includes a first inflatable region and a second inflatable region. The flow director is configured to direct the inflation gas directly into the first inflatable region. The first inflatable region and the second inflatable region are in fluidic communication, and a check valve permits the inflation gas to flow from the first inflatable region to the second inflatable region and prevents the inflation gas from flowing from the second inflatable region to the first inflatable region.
