Description
Die Erfindung betrifft einen Antrieb für einen Fahrzeugsitzeinsteller mit den Merkmalen des Oberbegriffs des Patentanspruches 1.The The invention relates to a drive for a vehicle seat adjuster with the features of the preamble of claim 1.
Aus
der
Der Erfindung liegt die Aufgabe zu Grunde, einen Antrieb der eingangs genannten Art zu verbessern. Diese Aufgabe wird erfindungsgemäß durch einen Antrieb mit den Merkmalen des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.Of the Invention is the object of a drive of the beginning to improve the type mentioned. This object is achieved by solved a drive with the features of claim 1. advantageous Embodiments are the subject of the dependent claims.
Dadurch, dass wenigstens ein Sperrelement in der Nullstellung das Abtriebselement sperrt und mit Auslenkung des Antriebshebels freigibt, wird der Antrieb zusätzlich gesperrt, so dass auch im Fall eines – beispielsweise aufgrund von Erschütterungen bei großen Toleranzen – ablaufenden Getriebes der Antrieb in der Nullstellung des Antriebshebels unbewegt bleibt. Das Sperrelement ist vorzugsweise sperrend oder freigebend vorgespannt, d.h. zu der Position hin, in der es den Antriebshebel sperrt, oder zu der Position hin, in der es den Antriebshebel freigibt. Hierzu ist das Sperrelement vorzugsweise als Sperrfeder ausgebildet, welche die Vorspannung selber aufbringt. Vorzugsweise ist diese Sperrfeder beim Sperren mit einer Rastnase in wenigstens ein Rastfenster des Abtriebselementes eingeklinkt, sichert dieses also in den Richtungen quer zur Rastnase formschlüssig. Mit mehreren Sperrelementen kann das Sperren nahezu stufenlos erfolgen.Thereby, that at least one blocking element in the zero position, the output element locks and releases with deflection of the drive lever, the Drive in addition locked, so even in the case of - for example, due to Shocks at large tolerances - expiring Getriebes the drive remains unmoved in the zero position of the drive lever. The blocking element is preferably preloaded in a blocking or releasing manner, i.e. to the position in which it locks the drive lever, or to the position in which it releases the drive lever. For this the blocking element is preferably designed as a locking spring, which the bias itself applies. Preferably, this locking spring when locking with a latch in at least one locking window of the Output element is latched, thus secures this in the directions form-fitting transversely to the locking lug. With several locking elements, the lock can be almost infinitely.
Zum Bewegen des Sperrelementes ist vorzugsweise ein Hubelement vorgesehen, welches wiederum vorzugsweise mittels des Antriebshebels bei einer Auslenkung desselben aus der Nullstellung bewegt wird. Das Hubelement weist vorzugsweise eine mit dem Antriebshebel zusammenwirkende Steuerkontur auf, welche die Schwenkbewegung des Antriebshebels in eine axiale Bewegung des Hubelementes umsetzt, beispielsweise mittels Schrägen. Auch das Sperrelement ist zum Sperren des Abtriebselementes vorzugsweise in axialer Richtung beweglich, so daß das Sperrelement beispielsweise mittels eines Vorsprungs des Hubelementes bewegt werden kann. Um das Hubelement leicht beweglich zu halten, ist dieses vorzugsweise mittels insbesondere angeformter Federgelenke beweglich aufgehängt. Vorzugsweise baut sich beim Bewegen des Hubelementes und/oder des Sperrelementes eine Rückstellkraft auf, welche durch Verstärkung der Vorspannung die selbsttätige Rückkehr in die Ausgangsposition unterstützt.To the Moving the blocking element is preferably provided a lifting element, which in turn preferably by means of the drive lever at a The same deflection is moved from the zero position. The lifting element preferably has a cooperating with the drive lever control contour on which the pivoting movement of the drive lever in an axial Moves the lifting element, for example by means of bevels. Also the blocking element is preferably for blocking the output element movable in the axial direction, so that the blocking element, for example can be moved by means of a projection of the lifting element. Around to keep the lifting element slightly movable, this is preferably suspended by means of particular molded spring joints movable. Preferably builds when moving the lifting element and / or the blocking element a restoring force, which by reinforcement the bias the automatic return supported in the starting position.
Durch ein translatorisch bewegliches Schubelement als einzukuppelndes Element kann ein und derselbe Bereich des einzukuppelnden Elementes mit ein und derselben Bewegung für die beiden möglichen Antriebsrichtungen verwendet werden. Dies spart Bauraum, so daß ein kompakter Antrieb möglich ist. Für Spezialanwendungen können auch mehrere Schubelemente vorgesehen sein. Das Schubelement ist vorzugsweise in radialer Richtung des Antriebsrades geführt, um eine definierte Bewegung beim Einkuppeln durchzuführen. Das Einkuppeln erfolgt, nachdem das Sperrelement bereits das Abtriebselement freigegeben hat. Vorzugsweise gelangt das Schubelement beim Einkuppeln in Eingriff mit dem Antriebsrad, vorzugsweise in Zahneingriff. Die Führung für das Schubelement ist vorzugsweise an einer Trägerplatte ausgebildet, welche nur beim Einkuppeln kraftschlüssig ortsfest gehalten wird, damit der Leerweg beim Einkuppeln möglichst gering ist.By a translationally movable thrust element as einzkuppelndes Element can one and the same area of the element to be coupled with one and the same movement for the two possible ones Drive directions are used. This saves space, so that a compact Drive possible is. For Special applications can also be provided several thrust elements. The push element is preferably guided in the radial direction of the drive wheel to to perform a defined movement when engaging. The Engaging takes place after the blocking element already has the output element has released. Preferably, the pusher passes during engagement in engagement with the drive wheel, preferably in meshing engagement. The guide for the push element is preferably on a support plate formed, which only force-locking stationary when engaging is held so that the free travel when engaging as possible is low.
Für die Umsetzung der Schwenkbewegung des Antriebshebels in die translatorische Bewegung des Schubelementes ist vorzugsweise ein Drehelement vorgesehen, welches vom Antriebshebel gedreht wird und über eine Kontur auf das in Kontakt mit ihm befindliche Schubelement einwirkt, wobei die Kontur die Drehbewegung des Drehelementes in eine translatorische Bewegung des Schubelementes umsetzt. Das Drehelement kann auch zur Übersetzung der Schwenkbewegung des Antriebshebels verwendet werden, indem vorzugsweise der Antriebshebel über eine Verzahnungsgeometrie mit Evolventen auf das Drehelement einwirkt, also eine Abwälzbewegung auftritt, welche bei entsprechendem Abstand zwischen der gemeinsamen Berührstelle und der jeweiligen Schwenkachse eine Vergrößerung des Schwenkwinkels erlaubt. Beim Auskuppeln kann das sich radial nach innen bewegende Schubelement das Drehelement in die Nullstellung zurückdrehen.For the implementation the pivoting movement of the drive lever in the translational movement of Pusher element is preferably provided a rotary member, which is rotated by the drive lever and a contour on the in Contact with it located pusher element, the contour the rotational movement of the rotary element in a translational movement the pushing element converts. The rotating element can also be used for translation the pivoting movement of the drive lever can be used by preferably the drive lever over a gearing geometry with involutes acts on the rotating element, So a rolling motion occurs, which at appropriate distance between the common contact point and the respective pivot axis allows an increase in the pivot angle. When disengaging the radially inward moving thrust element Turn the rotary element back to the zero position.
Zwischen dem Antriebsrad und dem Abtriebselement kann eine Überlastsicherung vorgesehen sein, welche bei Überschreiten einer Grenzlast das Antriebsrad vom Abtriebselement trennt und somit eine Beschädigung der Bauteile vermeidet. Die Überlastsicherung liegt bei der Momentenübertragung vorzugsweise im Kraftfluß und beruht auf einem kraftschlüssigen Prinzip, so daß ein eindeutiges und vollständiges Abtrennen der Antriebsseite sicher gestellt ist. Für die Überlastsicherung kann jede beliebige, an sich bekannte Ausführung verwendet werden, jedoch wird ein radial abtrennendes System bevorzugt.Between the drive wheel and the output element, an overload protection can be provided be, which separates the drive wheel from the output element when exceeding a limit load and thus avoids damage to the components. The overload protection is in the torque transmission preferably in the power flow and is based on a non-positive principle, so that a clear and complete separation of the drive side is ensured. For the overload protection, any known per se embodiment can be used, but a radially separating system is preferred.
Der erfindungsgemäße Antrieb kann für alle möglichen Fahrzeugsitzeinsteller verwendet werden, in der Regel wird er jedoch für Höheneinsteller, Lehnenein steller oder diverse Neigungseinsteller verwendet werden, die in einem entsprechend einstellbaren Fahrzeugsitz vorgesehen sind.Of the drive according to the invention can for all possible Vehicle seat adjuster can be used, but usually he will for height adjuster, Lehnenein be used or various inclination adjuster, provided in a correspondingly adjustable vehicle seat are.
