Abstract
An airbag for use within a motor vehicle, which includes a gas generator for supplying inflation gas; a lower chamber configured to be inflated directly by the gas generator; an upper chamber located above and proximate to the lower chamber; and a diffusing panel configured to separate the lower and upper chambers and allows inflation gas to pass through. The upper chamber is to be indirectly inflated by the gas generator through the diffusing panel, and upon completed deployment will have an internal pressure lower than the deployed internal pressure of the lower chamber.
