ABSTRACT:
The invention relates to an ignition device for a pyrotechnic occupant protective system which contains an ignition unit (18), an ignition switch (20) and an electronic unit (4). A voltage output (14) of the electronic unit (4) can be charged via an external supply line (10) up to a predetermined ignition voltage. The ignition switch (20) can be closed by a signal, which can be generated on the control output, so that the ignition voltage is discharged while passing through the ignition unit (18). The electronic unit (4) can be controlled in such a manner that test signals of a predeterminable duration can be generated on the control output (22) and the function of the ignition unit can be tested by using these test signals.
