ABSTRACT:
A dual chamber airbag cushion is disclosed for use in automotive protective systems. The airbag cushion comprises a first inflatable chamber and a second inflatable chamber disposed adjacent to the first inflatable chamber. In one embodiment, two opposing surfaces defining the second inflatable chamber are attached to one another at a plurality of attachment regions such that, upon inflation of the second chamber, the second chamber has a low profile region corresponding to the location of the attachment regions. An airbag cushion with dual chambers, each of which is inflated to a different pressure upon deployment, is thereby created.
