  • Circuit arrangement for triggering a safety system
    Patent number: 4933570
    Abstract: A circuit arrangement for triggering a safety system. A circuit arrangement serves the purpose of triggering a motor vehicle air bag system and contains an energy source, at least one release switch and at least two series branches connected in parallel and each branch has a tripping device for an air bag. A series capacitor is provided in every series branch, this capacitor limiting the current quantity in the tripped case in order to guarantee a reliable tripping of the further tripping device which acts with a time delay.

  • Circuit arrangement for the actuation of a safety system
    Patent number: 4845377
    Abstract: By way of an energy source, switches controlled by delay sensors activate a logic component. Dependent on the switch positions of the switches, of a seat switch and of a seat belt switch, the logic component controls an electronic ignition switch that connects a trigger for actuating a motor vehicle air bag system.

  • Trigger circuit for a safety system
    Patent number: 4804859
    Abstract: A response step switch for a motor vehicle airbag system has switch contacts driven by a delay sensor dependent on two response cases. Dependent on the position of a status switch, a logic module selects an electronic selection switch for enabling the triggering of the airbag via one of the switch contacts. The electronic selection switch is not driven until one of the response cases occurs, whereby the control energy comes from an energy source that also supplies the ignition energy for triggering.
