Abstract
A side-impact air bag system for motor vehicles with an air bag () extending across at least a part of the longitudinal extent of the vehicle. The air bag () is formed by two layers of fabric which are joined to each other and is located in the region of the roof frame of the vehicle in its folded state, before it is unfolded in the form of a curtain. An inflation device () releases an inflating gas, and the air bag () contains at least one primary chamber () which can be inflated by directly feeding gas into it, as well as at least one additional pressure equalization chamber (), which is separated from the immediately inflatable primary chamber (). The pressure equalization chamber () is equipped across its surface with additionally placed connections () of the fabric layers of the air bag () in such a manner that the gas stream entering the pressure equalization chamber () after inflation of the directly inflatable primary chamber () as a function of the pressure acting upon it, inflates portions of the pressure equalization chamber () by separation of the additional connections ().
