Abstract:
A device for triggering an occupant protection device of a motor vehicle, comprising:an energy source; a firing element for the occupant protection device; an electrically controllable switching device connected to said energy source and to said firing element for transmitting energy from said energy source to said firing element if said switching device is actuated; a control circuit connected to said switching device for impact-dependent actuation of said switching device; a testable acceleration switch generating a switching signal, the occupant protection device being triggered if said switching device is actuated and said testable acceleration switch supplies the switching signal to said switching device; a blocking device connected between said switching device and said control unit, said blocking device preventing actuation of said switching device during a test of said testable acceleration switch; said control circuit generating a test signal received by said testable acceleration switch and said blocking device, said blocking device being activated with a beginning of the test signal; and a timing element connected to said testable acceleration switch, and said timing element supplying the switching signal, which has a defined time duration, if said testable acceleration switch is activated, and said blocking device being deactivated with an end of the switching signal.
