The invention relates to an airbag system in a safety system, especially in motor vehicles, including a gas generator arranged in a gas guide housing (,), and at least one airbag connected to an assigned connection opening (,). The inventive airbag system also has a sliding element (,) which can be relatively displaced in the gas guide housing. The sliding element is provided as a valve element for controlling the inflation process of the airbag. An additional opening for connecting an additional airbag is configured in the airbag system. The sliding element is also configured as a sliding sleeve (,) which encompasses the tubular gas generator in a concentric manner and which can be displaced between an opened position and a closed position for the connection opening (,), the opening being radially configured in the wall of the gas guide housing (,).

Airbag system with controlled inflation

An airbag safety system has at least one airbag with inlets and a gas generator for generating a gas with which the at least one airbag is to be filled. An intermediate housing is connected between the gas generator and the at least one airbag. The gas is guided as a gas stream from the gas generator to the at least one airbag through the intermediate housing. The intermediate housing has outflow openings communicating with the inlets of the at least one airbag. A slide, positioned in the intermediate housing, is provided for controlling flow of the gas generated by the gas generator into the at least one airbag. The slide is displaceable relative to the inlets of the at least one airbag. An actuating member, mounted in the intermediate housing and positioned in the gas stream, is provided for generating a gas pressure force for displacing the slide. Controllably releasable securing elements for securing the slide at the intermediate housing in a rest position are provided. In the rest position, the cross-sectional area of the at least one outflow opening is unobstructed by the slide.
