摘要

Gas guides or airbag assemblies including gas guides are disclosed. The gas guides can direct inflation gas within an inflatable cushion. The gas guides can include a forward opening that delivers inflation gas to a forward portion of an inflatable cushion and a rearward opening that delivers inflation gas to a rearward portion of an inflatable cushion.
