Description
Die Erfindung betrifft einen Antrieb für eine Fahrzeugsitz-Einstellvorrichtung, insbesondere für einen Kraftfahrzeugsitz, mit den Merkmalen des Oberbegriffs des Patentanspruches 1.The The invention relates to a drive for a vehicle seat adjusting device, especially for one Motor vehicle seat, with the features of the preamble of claim 1.

Der Erfindung liegt die Aufgabe zu Grunde, einen Antrieb der eingangs genannten Art zu verbessern.Of the Invention is the object of a drive of the beginning to improve the type mentioned.
Diese Aufgabe wird erfindungsgemäß durch einen Antrieb mit den Merkmalen des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.These The object is achieved by a Drive solved with the features of claim 1. advantageous Embodiments are the subject of the dependent claims.
Dadurch, dass ein Ausgleichsteil vorgesehen ist, welches vom ersten Beschlagteil angetrieben relativ zum ersten Beschlagteil eine Drehbewegung mit überlagerter Taumelbewegung ausführt, kann bei geeigneter Parameterwahl ein zumindest weitgehender Ausgleich der beiden Taumelbewegungen erreicht werden. Die durch die Taumelbewegung entstehenden Antriebsmomentenschwankungen werden vermieden, und das Antriebsmoment wird verringert. Der dem Ausgleichsteil zugeordnete Abtrieb des erfindungsgemäßen Antriebs bildet eine integrierte Schnittstelle zur Fahrzeugsitz-Einstellvorrichtung. Die beiden Beschlagteile bilden für sich einen Getriebebeschlag mit Exzenterumlaufgetriebe, so dass die hohe Lastaufnahmefähigkeit und Spielfreiheit eines solchen Beschlags sich auf den erfindungsgemäßen Antrieb überträgt. Das Ausgleichsteil ist gleichachsig zum zweiten Beschlagteil angeordnet, womit ein vollständiger Ausgleich erfolgt, d.h. das Ausgleichsteil führt relativ zum zweiten Beschlagteil eine reine Drehbewegung aus.Thereby, that a compensation part is provided which from the first fitting part driven relative to the first fitting part a rotational movement with superimposed Wobbling movement, can with suitable parameter selection an at least substantial compensation the two tumbling movements are achieved. The by the tumbling motion arising driving torque fluctuations are avoided, and the drive torque is reduced. The balance of the associated output of the drive according to the invention forms an integrated interface to the vehicle seat adjuster. The two fitting parts form a geared fitting with eccentric planetary gear, so that the high load capacity and backlash of such a fitting transfers to the drive according to the invention. The Compensation part is arranged coaxially to the second fitting part, what a complete Balancing takes place, i. the compensation part leads relative to the second fitting part a pure rotary motion.
Eine kompakte Bauweise ergibt sich, wenn das erste Beschlagteil axial zwischen dem zweiten Beschlagteil und dem Ausgleichsteil angeordnet ist. Bei scheibenförmigen Beschlagteilen und einem ebensolchen Ausgleichsteil ist vorzugsweise ein Umklammerungsring vorgesehen, welcher das zweite Beschlagteil und das Ausgleichsteil – und vorzugsweise auch das dazwischen angeordnete erste Beschlagteil axial zusammenhält. Der Umklammerungsring kann am zweiten Beschlagteil befestigt sein und das Ausgleichsteil übergreifen, insbesondere unter Zwischenlage eines radial wirksamen Lagerrings.A compact design results when the first fitting part axially arranged between the second fitting part and the compensation part is. In disk-shaped Fitting parts and a similar compensation part is preferably a Umklammerungsring provided which the second fitting part and the compensation part - and preferably also the first fitting part arranged therebetween holds together axially. The Umklammerungsring may be attached to the second fitting part and overlap the compensation part, in particular with the interposition of a radially effective bearing ring.
Um die gewünschte Bewegung zwischen Ausgleichsteil und erstem Beschlagteil zu erzeugen, wird ein Getriebeaufbau entsprechend demjenigen zwischen den beiden Beschlagteilen gewählt. Am Ausgleichsteil ist beispielsweise ein Hohlrad ausgebildet, d.h. eine Innenverzahnung vorgesehen, welches vorzugsweise mit einer Außenverzahnung des ersten Beschlagteils kämmt. Ebenso ist es möglich, dass das Ausgleichsteil eine Außenverzahnung und das erste Beschlagteil eine Innenverzahnung aufweist. Herstellungstechnisch wird die Variante bevorzugt, bei welcher das erste Beschlagteil auf seinen beiden Seiten insgesamt genau eine Innenverzahnung und genau eine Außenverzahnung aufweist, da diese dann in einem Herstellungsschritt erzeugt werden können und sich nur eine gering schwankende Materialstärke ergibt. Ähnlich verhält es sich mit dem Ausgleichsteil, bei dem insbesondere im Falle einer Ausbildung mit Hohlrad vorzugsweise ein Ritzel als Abtrieb ausgebildet ist.Around the desired Movement between compensating part and the first fitting part is generated a gear assembly corresponding to that between the two fitting parts selected. On the compensation part, for example, a ring gear is formed, i. an internal toothing provided which preferably with a external teeth the first fitting part meshes. Likewise it is possible that the compensation part an external toothing and the first fitting part has an internal toothing. production engineering the variant is preferred in which the first fitting part on its two sides in total exactly one internal toothing and exactly one external toothing since these are then produced in one production step can and results in only a slight fluctuation in material thickness. The situation is similar with the compensation section, in particular in the case of training with ring gear preferably a pinion is designed as an output.
Der erfindungsgemäße Antrieb kann beispielsweise für einen Höheneinsteller oder Neigungseinsteller in allen Fahrzeugsitzen mit einstellbaren Baugruppen, beispielsweise mit neigungseinstellbarer Lehne oder höhen- und/oder neigungseinstellbarem Sitzteil, eingesetzt werden. So kann der Antrieb für einen Höheneinsteller eingesetzt werden, welcher wenigstens ein Viergelenk mit Getriebegliedern aufweist, wobei das zweite Beschlagteil fest mit einem ersten der Getriebeglieder verbunden ist und das Ritzel ein mittels eines Gelenks am ersten Getriebeglied angelenktes, zweites Getriebeglied (in welches das Ritzel beispielsweise an einem Zahnbogen eingreift) um das Gelenk relativ zum ersten Getriebeglied schwenkt.Of the drive according to the invention can be for example a height adjuster or tilt adjuster in all vehicle seats with adjustable Assemblies, for example with tilt adjustable backrest or height and / or tilt adjustable seat part, are used. So can the drive for a height adjuster be used, which at least a four-bar linkage with gear members , wherein the second fitting part fixed to a first of the Gear members is connected and the pinion by means of a joint articulated on the first gear member, the second gear member (in which the pinion engages, for example, on a dental arch) around the joint pivots relative to the first gear member.
