A device for disconnecting the flow of current in the positive or impregnated battery cable of a motor vehicle has an electrically conductive plug-in connection that can be placed in the positive or impregnated battery cable in the form of a housing and a plug connector. The housing contains a gas generator of the kind used, for example, for belt tighteners. The gas generator is arranged in the housing in such a way that the propellant gas produced when the gas generator is ignited electrically separates the connector from the housing and this in turn interrupts the flow of current in the positive or impregnated battery cable. Consequently, a short circuit that might occur in the event of an accident and which could otherwise lead to damage of the cable tree and then set the vehicle on fire, is avoided in good time.

Gas generator for an airbag that provides protection against side impact in a vehicle. The gas generator has a housing with a flange for attaching the gas generator to a part of the vehicle, in particular to the backrest of a vehicle seat, and for fixing the airbag. The gas generator also has a sealed fluid-tight propellant tank that acts as combustion chamber. The propellant tank is arranged concentrically in the housing such that an annular chamber is formed between the housing and the propellant tank to allow afterburning. The annular chamber can be connected on the one hand to the inside of the propellant tank through the passage that opens as a result of the burning process and on the other hand to the inside of the airbag through the outlet apertures provided in the housing wall, but otherwise it is sealed fluid-tight. The construction of the generator is therefore very simple and it is of very small size.
