Abstract
The invention relates to a non return valve for an airbag of a vehicle passenger retention system, which is provided with a connection hose between two chambers of the airbag, wherein in the connector hose a fabric inlay is accommodated. The fabric inlay subdivides the connection hose into a flow passage between the first and the second chamber and a pressure chamber which is in connection with the second chamber. As soon as the internal pressure in the first chamber is greater than that in the second chamber the fabric inlay opens the flow passage. If on the contrary the internal pressure in the second chamber is greater than that in the first chamber the fabric inlay closes off the flow passage by means of the internal pressure which acts in the pressure chamber.
