Abstract
Description
Die Erfindung betrifft eine Verriegelungseinrichtung eines Fahrzeugsitzlängseinstellers mit den Merkmalen des Oberbegriffs des Anspruches 1.The invention relates to a locking device of a vehicle seat adjuster with the features of the preamble of claim 1.
Eine Verriegelungseinrichtung dieser Art ist aus der
Der Erfindung liegt die Aufgabe zu Grunde, eine Verriegelungseinrichtung der eingangs genannten Art zu verbessern. Diese Aufgabe wird erfindungsgemäß durch eine Verriegelungseinrichtung eines Fahrzeugsitzlängseinstellers mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.The invention is based on the object to improve a locking device of the type mentioned. This object is achieved by a locking device of a vehicle seat adjuster with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.
Durch das Vorsehen von zwei in Längsrichtung der Schienen relativ zueinander begrenzt verschiebbaren Verriegelungsmitteln kann eine Spielfreiheit der Verriegelung erzeugt werden, so dass eine derartige Verriegelungseinrichtung keine Klappergeräusche verursacht.By providing two locking means which are displaceable relative to one another in the longitudinal direction of the rails, a backlash of the lock can be generated so that such a locking device does not cause rattling noises.
Insbesondere bevorzugt weist mindestens eines der Verriegelungsmittel, insbesondere bevorzugt jedoch beide Verriegelungsmittel, einen Keilzahn mit einer Keilfläche auf. Ist an jedem der Verriegelungsmittel jeweils ein Keilzahn vorgesehen, so sind die Keilflächen der Keilzähne auf entgegengesetzten Seiten angeordnet. Dadurch ergibt sich ein optimaler Spielausgleich in Verbindung mit der relativen Verschiebbarkeit der Verriegelungsmittel zueinander.Particularly preferably, at least one of the locking means, but in particular preferably both locking means, has a splined tooth with a wedge surface. If a splined tooth is provided on each of the locking means, the wedge surfaces of the spline teeth are arranged on opposite sides. This results in an optimal clearance compensation in conjunction with the relative displacement of the locking means to each other.
Bevorzugt sind die Verriegelungsmittel der Verriegelungseinrichtung spiegelbildlich in Bezug auf eine Ebene ausgestaltet und angeordnet, die senkrecht zu den Längsachsen der Schienen angeordnet ist.Preferably, the locking means of the locking device are configured and arranged in mirror image with respect to a plane which is perpendicular to the longitudinal axes of the rails.
Die Verriegelungsmittel weisen vorzugsweise eine gemeinsame Schwenkachse auf, um welche sie verschwenkbar sind, insbesondere im Wesentlichen unabhängig von einander. Dadurch kann sichergestellt werden, dass zumindest eines der Verriegelungsmittel verriegelt, wobei jedoch für eine spielfreie Verriegelung eine Einfallen beider Verriegelungsmittel erforderlich ist.The locking means preferably have a common pivot axis about which they are pivotable, in particular substantially independent of each other. This can ensure that at least one of the locking means locked, but for a play-free locking a collapse of both locking means is required.
Jedes Verriegelungsmittel weist bevorzugt mindestens einen, insbesondere bevorzugt genau zwei Zähne und genau einen Keilzahn auf.Each locking means preferably has at least one, in particular preferably exactly two, teeth and exactly one splined tooth.
Im verriegelten Zustand sind bevorzugt die beiden Keilflächen der Keilzähne in Anlage an Seitenflächen von Ausnehmungen der ersten Schiene, wohingegen die Seitenflächen der Keilzähne zumindest leicht beabstandet von den gegenüberliegenden Seitenflächen der Ausnehmungen der ersten Schiene sind. Ferner sind die Seitenflächen der Keilzähne in Anlage an Seitenflächen von Ausnehmungen der zweiten Schiene, wohingegen die Keilflächen der Keilzähne zumindest leicht beabstandet von den gegenüberliegenden Seitenflächen der Ausnehmungen der zweiten Schiene sind. Dadurch ergibt sich ein direkter Kraftfluss über die Keilzähne von einer Schiene zur anderen Schiene.In the locked state, the two wedge surfaces of the splines are preferably in abutment with side surfaces of recesses of the first rail, whereas the side surfaces of the splines are at least slightly spaced from the opposite side surfaces of the recesses of the first rail. Further, the side surfaces of the spline teeth are in abutment with side surfaces of recesses of the second rail, whereas the wedge surfaces of the spline teeth are at least slightly spaced from the opposite side surfaces of the recesses of the second rail. This results in a direct force flow over the splines from one rail to the other rail.
