Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Straffen eines Fahrzeug-Sicherheitsgurtes nach dem Oberbegriff des Patentanspruches 1.The The invention relates to a device for tightening a vehicle seat belt according to the preamble of claim 1.

Aus
Der Anschluss an die elektrische Zündeinrichtung erfordert bei den herkömmlichen Vorrichtungen eine zweipolige Stecker-/Buchseneinrichtung, um die elektrische Zündeinrichtung für ihre Betätigung mit der Steuereinrichtung zu kontaktieren. Selbst bei entsprechender Markierung besteht hierbei die Gefahr der Verpolung oder auch der Zerstörung der dünnen Steckerstifte, da der elektrische Anschluss nur innerhalb eines begrenzten, zur Verfügung stehenden Raums erfolgen muss.Of the Connection to the electrical ignition device requires in the conventional Devices a bipolar plug / socket device to the electric ignition device for your activity to contact with the controller. Even with appropriate Marking here is the danger of reverse polarity or the destruction the thin one Pins, because the electrical connection only within one limited, available standing room.
Aufgabe der Erfindung ist es daher, eine Vorrichtung der eingangs genannten Art zu schaffen, bei welcher die elektrische Kontaktierung der Zündeinrichtung für das pyrotechnische Treibmittel vereinfacht ist.task The invention is therefore an apparatus of the aforementioned To create type, in which the electrical contacting of the ignition device for the pyrotechnic blowing agent is simplified.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst. Weitere vorteilhafte Ausgestaltungen sind Gegenstand von Unteransprüchen.These The object is achieved by the characterizing features of claim 1 solved. Further advantageous embodiments are the subject of dependent claims.
Bei der Erfindung erfolgt die elektrische Masseanbindung der Zündeinrichtung über das wenigstens eine elektrisch leitfähige Zugkabel an das Massepotential des Fahrzeugs. Hierzu kann das Zugkabel durch ein Kontaktelement, welches vorzugsweise mit Druckkontakt mit dem Zugkabel in Berührung steht, elektrisch mit dem Fahrzeugaufbau, beispielsweise einem am Fahrzeugaufbau vorgesehenen Befestigungsmittel elektrisch verbunden werden. Das Befestigungsmittel, welches in Form eines Befestigungsbeschlages ausgebildet sein kann, dient zur Befestigung einer Kabelführung am Fahrzeugaufbau. In der Regel besteht die Kabelführung aus einem elektrisch nicht leitenden Material, beispielsweise Kunststoff. Die elektrische Kontaktgabe zwischen dem Zugkabel und dem Befestigungsmittel und somit mit dem Fahrzeugaufbau, welcher das elektrische Massepotential des Fahrzeugs hat, erfolgt im Bereich dieser Kabelführung.at the invention, the electrical ground connection of the ignition device via the at least one electrically conductive Pull cable to the ground potential of the vehicle. For this purpose, the pull cable by a contact element, which preferably with pressure contact in contact with the pull cable is electrically connected to the vehicle body, for example an am Vehicle structure provided fastening means electrically connected become. The fastener, which in the form of a mounting bracket may be formed, is used to attach a cable guide on Vehicle body. In general, the cable management consists of an electrical non-conductive material, such as plastic. The electric Contact between the pull cable and the fastener and thus with the vehicle body, which is the electrical ground potential of the vehicle takes place in the area of this cable guide.
Das Zugkabel, welches aus Metalldrähten gebildet wird, und gegebenenfalls einen elektrisch leitenden Schutzüberzug, insbesondere aus Zink, aufweist, ist elektrisch leitfähig und mit dem einen ebenfalls elektrisch leitfähigen Mantel aufweisenden Kolben fest verbunden. Durch diese feste Verbindung wird zwischen dem Zugkabel und dem Kolben eine elektrische Verbindung hergestellt. Der Mantel des Kolbens besteht vorzugsweise aus Stahl. Zwischen dem Kolben und der Zündeinrichtung, welche in herkömmlicher Weise als Zündpille oder dergleichen ausgebildet sein kann, erfolgt ebenfalls eine elektrische Verbindung. Auf diese Weise lässt sich die Masseanbindung der Zündeinrichtung über ohnehin an der Straffervorrichtung vorhandene Konstruktionselemente herstellen. In bevorzugter Weise wird damit die Masseanbindung für die Zündeinrichtung durch den Kolben der Antriebseinrichtung, das Zugkabel, das mit dem Zugkabel vorzugsweise in Druckkontakt stehende Kontaktelement und das Befestigungsmittel, beispielsweise in Form eines Beschlagteils hergestellt.The Pull cable, which is made of metal wires is, and optionally an electrically conductive protective coating, in particular of zinc, is electrically conductive and with the one also electrically conductive jacket having pistons firmly connected. Through this fixed connection is between the pull cable and the piston made an electrical connection. The coat of the Piston is preferably made of steel. Between the piston and the ignition device, which in conventional Way as a squib or the like may be formed, also takes place an electrical Connection. That way the ground connection of the ignition device on anyway produce construction elements present on the pretensioner device. In a preferred manner, so that the ground connection for the ignition device the piston of the drive device, the pull cable, with the pull cable preferably in pressure contact contact element and the fastening means, for example, produced in the form of a fitting part.
Um die Zündeinrichtung zu betätigen, genügt ein einpoliger Anschluss für eine das Zündsignal führende elektrische Leitung. Hierdurch wird eine wesentliche Erleichterung der elektrischen Anbindung der Zündeinrichtung nach außen, beispielsweise an eine entsprechende Steuereinrichtung erreicht und die Gefahr der Verpolung beim Anschluss vermieden.Around the ignition device to press, is enough single pole connection for one the ignition signal premier electrical line. This will be a significant relief the electrical connection of the ignition device outward, For example, achieved at a corresponding control device and avoids the risk of reverse polarity when connecting.
