Abstract:
A device for actuating an airbag comprising:a controller, a firing means for firing the airbag, electric leads which connect the controller to the firing means, a damping coil connected into the electric leads for damping high-frequency interference currents, said coil inducing interference currents in the leads to the firing means in the presence of an external electromagnetic interference field, a compensation coil connected into the electric leads in order to reduce the influence of the external electromagnetic interference field and wherein said compensation coil is arranged in the vicinity of the damping coil in such a way that the induced current of the compensation coil counteracts the interference current induced by the external interference field in the damping coil, and wherein one end of the damping coil is electrically connected to one end of the compensation coil wherein the damping coil and the compensation coil are connected in series in the same electric lead.
