Patent ID: 7661699

Claim:
An airbag system for a motor vehicle, comprising: an inflatable gasbag having at least a first and a second chamber connected to each other along a connecting portion; an inflator for inflating the first and second chambers of the gasbag; and a mass flow divider associated with the inflator and arranged in the connecting portion of the gasbag such that gas ejected by the inflator is guided into both the first and second chambers of the gasbag by the mass flow divider, wherein at least one protective layer extends from the mass flow divider into the first chamber to protect at least a portion of the first chamber from the gas guided into the first chamber by the mass flow divider, wherein upon inflation of the gasbag, an inner pressure in the first chamber is significantly higher than an inner pressure in the second chamber, wherein the protective layer comprises a flexible material deformed by the inner pressure in the first chamber to prevent gas from flowing from the first chamber through the connecting portion into the second chamber, and wherein upon inflation of the gasbag, the inner pressure in the first chamber leads to deformation of the protective layer so that the protective layer closes the connecting portion of the gasbag.
