Description
Die Erfindung betrifft eine Sitzlängsverstellung für Kraftfahrzeugsitze nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a seat-length adjustment for motor vehicle seats according to the preamble of claim 1.
Eine derartige Sitzlängsverstellung ist insbesondere auch geeignet zur Verstellung der Längsposition einer Sitzbank, wie z.B. der hinteren Sitzbank eines Personenkraftwagens bzw. einer Großraumlimousine (Van), wobei bei letzterer die hintere Sitzbank üblicherweise der dritten Sitzreihe entspricht.A such seat longitudinal adjustment is particularly suitable for adjusting the longitudinal position a seat, e.g. the rear seat of a passenger car or a large-capacity sedan (Van), where in the latter, the rear seat usually the third row of seats equivalent.

Der Erfindung liegt die Aufgabe zugrunde, eine Sitzlängsverstellung für Kraftfahrzeugsitze der eingangs genannten Art weiter zu verbessern, insbesondere im Hinblick auf eine gleichmäßige, klapperfreie Verstellbarkeit in Sitzlängsrichtung, um eine zuverlässige, spielfreie Führung des Gleitelementes in der Führungsschiene ohne die Gefahr eines Verkantens zu erreichen.Of the Invention is based on the object, a seat longitudinal adjustment for motor vehicle seats of the type mentioned above, in particular in Regard to a uniform, rattle-free Adjustability in seat longitudinal direction, a reliable, play-free guidance of the sliding element in the guide rail without the risk of jamming.
Dieses Problem wird erfindungsgemäß durch die Schaffung einer Sitzlängsverstellung mit den Merkmalen des Patentanspruchs 1 gelöst.This Problem is inventively the creation of a seat length adjustment solved with the features of claim 1.
Danach ist bei einer Sitzlängsverstellung mit mindestens einer längserstreckten Führungsschiene, die zwei einander gegenüberliegende Führungsflächen aufweist, und mindestens einem an der Führungsschiene gelagerten, in Schienenlängsrichtung verschiebbaren Gleitelement, das Gleitelement quer zur Schienenlängsrichtung gegen die Führungsschiene elastisch vorgespannt, so daß sich das Gleitelement unter Vorspannung an der Führungsschiene abstützt.After that is in a seat-length adjustment with at least one elongated one Guide rail, the two opposite ones Having guide surfaces, and at least one on the guide rail mounted, displaceable in the rail longitudinal direction Sliding element, the sliding element transversely to the rail longitudinal direction against the guide rail elastically biased so that the sliding element is supported under pretension on the guide rail.
Hierbei ist das Gleitelement schwenkbar an einem Teil der Sitzstruktur (insbesondere des Sitzgestells) angelenkt und entlang einer Drehrichtung um seine Schwenkachse gegen die Führungsschiene vorgespannt. Dabei weist das Gleitelement einen bogenförmigen Abschnitt auf, über den sich das Gleitelement an der einen Führungsfläche abstützt. An der anderen Führungsfläche der Führungsschiene stützt sich das Gleitelement mit einem exentrisch bezüglich der Drehachse ausgebildeten Abschnitt (Nocken) ab.in this connection the sliding element is pivotable on a part of the seat structure (in particular the seat frame) and along a direction of rotation about his Swivel axis biased against the guide rail. In this case, the sliding element has an arcuate portion over which the sliding element is supported on the one guide surface. At the other guide surface of the guide rail based the slider with an eccentric with respect to the axis of rotation formed Section (cams) off.
Mit der erfindungsgemäßen Lösung wird ein Verkanten des mindestens einen Gleitelementes in oder an der Führungsschiene vermieden und gleichzeitig eine spielfreie Lagerung des Gleitelementes an der Führungsschiene ermöglicht.With the solution according to the invention is a tilting of the at least one sliding element in or on the guide rail avoided while a backlash-free storage of the sliding element on the guide rail allows.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Patentansprüchen angegeben.Further advantageous embodiments of the invention are specified in the dependent claims.
