Abstract
Description
Die Erfindung betrifft eine Verriegelungsvorrichtung mit den Merkmalen des Oberbegriffs des Anspruches 1.The The invention relates to a locking device with the features of the preamble of claim 1.
Aus
der
Der Erfindung liegt die Aufgabe zu Grunde, eine Verriegelungsvorrichtung der eingangs genannten Art zu verbessern. Diese Aufgabe wird erfindungsgemäß durch eine Verriegelungsvorrichtung mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.Of the Invention is based on the object, a locking device to improve the type mentioned. This object is achieved by a locking device with the features of claim 1 solved. Advantageous embodiments are the subject of the dependent claims.
Die erfindungsgemäße Verriegelungsvorrichtung kann in diversen crashaktiven Einheiten eines Fahrzeugsitzes, beispielsweise einer Kopfstütze oder einem Antisubmariningbügel, eingesetzt werden, aber auch in allgemeiner Anwendung als Schloss ("Elektro-Schloss") eingesetzt werden, beispielsweise zum Befestigen eines Fahrzeugsitzes oder einer Lehne an der Karosserie, für einen Kofferraumdeckel oder eine Motorhaube, oder für das Abklappen oder Aufstellen von Fondkopfstützen. Dadurch, dass die Magneteinheit und das Getriebe aus den Hebeln und/oder Klinken innerhalb eines weitgehend geschlossenen Gehäuses einer Aktuatorbox angeordnet sind, steht für eine modulare Bauweise eine kompakte Baugruppe zur Verfügung, was den Zusammenbau der vorgenannten Einheiten vereinfacht. Das Getriebe übersetzt die Haltekraft der Magneteinheit zu einer Gegenkraft zur Federkraft der antreibenden Feder oder baut diese Gegenkraft auf. Die Hebel und Klinken können dabei ein beispielsweise 3-Klinken-System oder ein Kniehebel-System bilden, welches selbsthemmend oder nicht-selbsthemmend sein kann. Die Magneteinheit kann als Hub- oder Zugmagnet (wobei dann das Getriebe die Gegenkraft aufbauen muss) oder als Haftmagnet (wobei dann das Getriebe übersetzt) ausgebildet sein. Der Haftmagnet kombiniert einen Permanentmagnet und einen Kompensations-Elektromagneten mit Feldkompensation oder Kraftkompensation, wobei letzteres eine verbesserte Abstimmung ermöglicht. Das Getriebe muss nicht direkt die Feder halten, sondern kann auch einen von dieser beaufschlagten Bügel halten.The Locking device according to the invention can in various crash-active units of a vehicle seat, for example a headrest or an anti-submarine bar, be used, but also in general use as a lock ("Electric lock") are used, For example, for securing a vehicle seat or a backrest on the body, for a trunk lid or bonnet, or for folding or setting up rear headrests. Because the magnet unit and the gearbox are out of the levers and / or pawls within a largely closed housing a Aktuatorbox are arranged, stands for a modular design compact assembly available, which simplifies the assembly of the aforementioned units. The Gear translated the holding force of the magnet unit to a counterforce to the spring force the driving spring or builds up this drag. The levers and pawls can while an example 3-pawl system or a toggle system form, which may be self-locking or non-self-locking. The magnet unit can be used as a lifting or pulling magnet (in which case the transmission must build the counterforce) or as a magnet (in which case the Gear translated) be educated. The magnet combines a permanent magnet and a compensating electromagnet with field compensation or Force compensation, the latter allows improved tuning. The gearbox does not have to hold the spring directly, but also can hold one of these acted upon hanger.
Die Hebel und Klinken des Getriebes bilden vorzugsweise eine Kette von Getriebegliedern, die im Normalfall das jeweils nächste Getriebeglied sperren und/oder festhalten, um so die Haltekraft der Magneteinheit bis zur Feder zu übersetzen. Die Hebel und Klinken des Getriebes sind vorzugsweise schwenkbar, um mit wenigen Freiheitsgraden eine definierte Gesamtbewegung zu erreichen. Entsprechend geben die Hebel und Klinken im Crashfall (oder sonstigen Auslösefall, beispielsweise Precrashfall) die Feder durch Schwenken frei.The Levers and pawls of the transmission preferably form a chain of Transmission links, which are normally the next transmission link lock and / or hold so as to hold the holding force of the magnet unit to translate to the spring. The levers and pawls of the transmission are preferably pivotable, with a few degrees of freedom to a defined total movement to reach. Accordingly, the levers and pawls give in the event of a crash (or other trigger case, for example Precrashfall) free the spring by pivoting.
Die Hebel und Klinken des Getriebes sind vorzugsweise so aufeinander abgestimmt, dass nach dem Crashfall (oder sonstigen Auslösefall) durch Einführen der Feder (oder des Bügels) und Schwenken der Klinken und Hebel die Magneteinheit wieder sperren und/oder festhalten kann, also ein Zurücksetzen der Kopfstütze erfolgt, ohne dass ein gesondertes Werkzeug notwendig ist. Hierfür hält nach dem Crashfall vorzugsweise einer der Hebel die die Feder aufnehmende Klinke geöffnet.The Levers and pawls of the transmission are preferably so each other agreed that after the crash (or other trigger case) by introducing the spring (or the strap) and swing the latches and levers to lock the magnet unit again and / or can hold, so there is a reset of the headrest, without a separate tool is necessary. For this holds after the Crash case preferably one of the levers which receives the spring Latch open.
