Igniter for pyrotechnical vehicle device, e.g. safety belt tightener, propellant charge has second ignition element connected to second anode connection optionally connectable in parallel with first

摘要

The device has an initial ignition set that can be ignited by applying a voltage to a first ignition element (18a) with a defined Ohmic impedance between a first anode connection (12a) and a first cathode connection (16a). At least one second ignition element (18b) with a defined Ohmic resistance is provided and connected to a second anode connection (12b) in parallel with the first anode connection and able to be optionally connected.
