Abstract
A device for triggering an airbag having a controller, a trigger, electric lines between the controlled device and the trigger and a coil for attenuating high-frequency interference currents connected to the electric lines which in turn induces interference current into the lines as a result of an external magnetic alternating field. The attenuation of the induced interference current results from an external magnetic alternating field of the coil and a compensating coil is connected in the electric lines and arranged in the surrounding area of the coil so that the amount of current induced in the compensating coil is equal to that of the interference current induced in the coil by the external field and because they are in anti-phase, the resultant current is zero from any interference.
