Abstract

The invention relates to an airbag apparatus for motor vehicles, in particular to a side airbag apparatus comprising a gas generator and a gas filling tube. The tube is provided along its length at predetermined distances gas overflow openings. The openings are connected to an inflatable gas bag which extends at least over a greater portion of the length of the tube and preferably consists of individual cells. Each cell is associated with a pair of gas outflow openings. The gas outflow openings are formed by incisions in the wall of the gas filling tube and by indentations of the tube wall material on one side of the incisions and extending at an angle to the tube axis.
