Abstract

The safety system has a power switch directly on the battery that interrupts the circuit in the motor vehicle, a fixed conducting track and a contact that is movable by a piston arranged in a housing. The piston is movable by the magnetic effect of a coil (1) and closes the contact path.

  • b. eine elektrische Art (2)
The system can be built with 2 circuit breakers
  • a. a pyrotechnic species ( 1 )
  • b. an electrical type ( 2 )

a. Leistungsschalter für ein Sicherheitssystem zur Stromabschaltung im KFZ bei einem Crash, der durch ein von einem Sensor abgegebenes und in eine Elektronik entsprechend aufbereitetes Signal aktiviert wird, dadurch gekennzeichnet, dass ein feststehender und ein mittels Kolben längsbeweglicher Kupferleiter in einem isolierten Gehäuse angeordnet ist, wobei der Kolben, durch eine Feder druckbelastet, den längsbeweglichen Leiter mit dem ortsfesten Leiter elektrisch kontaktiert und am entgegengesetzten Ende des Kolbenweges Rastvorrichtungen zum Festhalten des Kolbens beim Unterbrechen der elektrischen Leitung angeordnet sind und dass ein Gasgenerator, in Form einer Zündpille, zur Druckbeaufschlagung des Kolbens, entgegen der Federwirkung im Gehäuse, das außerdem mit Druckausgleichsbohrungen versehen ist, angeordnet ist.a. Circuit breaker for a security system for switching off the power in the vehicle in the event of a crash caused by a Sensor emitted and processed accordingly in electronics Signal is activated, characterized in that a fixed and a copper conductor which can be moved longitudinally by means of pistons in an insulated housing is arranged, the piston being pressure-loaded by a spring, the longitudinally movable Electrical contact with the fixed conductor and on the opposite End of the piston path locking devices to hold the piston are arranged when the electrical line is interrupted and that a gas generator, in the form of a squib, for pressurization of the piston, against the spring action in the housing, which also has pressure compensation holes is provided, is arranged.

Circuit breaker for security system Power cut-off in the vehicle in the event of a crash caused by a sensor emitted signal and processed accordingly in electronics is activated, characterized in that a fixed contact path and a piston which is longitudinally movable Contact in a housing is arranged.

Der Kolben wird mittels der Magnetwirkung der Spule bewegt und schließt die Kontaktbahn.The piston is driven by the magnetic action of the The coil moves and closes the contact path.

Bei Unterbrechung der Stromzuführung zur Spule (Crash) holt eine Feder den Kolben mit dem Kontakt in die Ruhelage zurück und unterbricht die elektrische Verbindung zur Batterie.When the power supply to the coil is interrupted (Crash) a spring brings the piston into contact with the contact back and cuts the electrical connection to the battery.
