Abstract

An expandable airbag cushion assembly includes an internal inflatable pouch enclosed in an expandable external pocket and an inflator for directing gas into the internal inflatable pouch. The airbag cushion assembly may be enclosed in a flat panel casing that does not require the folding of the expandable external pocket when the airbag is deflated. The packaging size of an airbag assembly is relatively small compared to other airbag assemblies known the art. The smaller packaging size provides a car manufacturer with increased flexibility concerning the installation location of a vehicle airbag assembly. In turn, the capability to install an airbag in more locations within a passenger compartment provides the vehicle'"'"'s occupants with better protection in the case of a collision.
