SAFETY DEVICE FOR VEHICLE PASSENGERS

摘要

A safety device having an electric component, in particular a restraining system such as an airbag and/or a belt tensioner, for the passengers of vehicles provided with their own electric supply system, has an energy supply stand-by circuit to temporarily maintain the voltage supply required to trigger the safety device. To ensure a reliable operation, the safety device is disconnected from the voltage (Un) of the electric supply system of the vehicle and is connected to the energy supply stand-by circuit (9) when the voltage (NN) of the electric supply system of the vehicle exceeds a predeterminable maximum value (Umax).
