2.1 Containers filled with a pressurised gas, for airbag systems usually have valves which are composed of wall components which can be suddenly broken out of the wall of the pressurised container. In such designs, the pressurised gas flows too rapidly and in an uncontrolled fashion into the impact bag which does not always unfold as desired.
2.2 It is proposed to construct the wall element which can be broken out as a part of the wall of a hollow valve block which is provided with the outflow opening, to provide the wall element with a projection protruding into the inside of the valve block and to guide in a transversely displaceable manner with respect to the projection in the valve block the piston rod which can be moved by a pyrotechnic propelling charge and serves to break out the wall component, and it is proposed to provide the piston rod with a collar which in the case of ignition comes to rest on the projection and thus does not lead to a sudden breaking out but rather to a swivelling of the wall element before its ultimate breaking out.
2.3 Use for airbag systems of motor vehicles.
