Die Erfindung bezieht sich auf eine Feststellvorrichtung für Gleitschienenfuhrungen von Fahrzeugsitzen die sich zusammensetzt aus einer parallel zu den Gleitschienen verlaufenden und mit einer der beiden Gleitschienen starr verbundenen Rastschicne, in der in regelmässigen Abständen Rastöffnungen eingearbeitet sind und aus einem verschwenkbar in einem starr mit der anderen Gleitschiene verbundenen Lagerträger gelagerten Riegel, der mit mindestens einem in die Rastausnehmungen der Rastschiene eingreifenden Rastnocken versehen und von einer Rückstellfeder in Raststellung gehalten ist.The invention relates to a locking device for slide rails of vehicle seats which is assembled from a locking rail running parallel to the slide rails and rigidly connected to one of the two slide rails, in which locking openings are incorporated at regular intervals and can be pivoted into one rigidly with the other slide rail connected to the bearing bracket mounted bolt, which with at least one in the recesses of the Locking rail engaging locking cam provided and is held in the locking position by a return spring.
Bei den bekannten Feststellvorrichtungen dieser Art sind die Rastschienen aus etwa 2 mm dickem Stahlblech hergestellt. Nach großen Belastungen und nach längerer Betriebszeit verformt der Rastnocken durch die von den Rüttelbewegungen des Fahrzeuges herrührenden Stöße die Form der Rastausnehmungen, so daß zwischen dein in Raststellung befindlichen Rastnocken und denIn the known locking devices of this type, the locking rails are made of approximately 2 mm thick sheet steel. To heavy loads and after a long period of operation, the locking cam deforms due to the shaking movements of the vehicle resulting impacts the shape of the locking recesses, so that between your in the locking position and the locking cams
Seitenwänden der Rastausnehmungen ein Spalt entsteht, so daß eine spielfreie Feststellung der Gleitschienenführung nicht mehr möglich ist.Side walls of the locking recesses creates a gap so that a backlash-free fixing of the slide rail guide is no longer possible.
Aufgabe der vorliegenden Erfindung ist es, eine Feststellvorrichtung für Gleitschienenführungen »u schaffen, die eine spielfreie Verriegelung der Gleitschienenführung auch nach langer Betriebszeit unter hoher Belastung sichert.The object of the present invention is to create a locking device for slide rail guides which lock the slide rail guide without play even after a long period of time Ensures operating time under high loads.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Rastausnehmungen in der Rastschiene und der darin eingreifende Rastnccksn zur Sohle der Ausnehmungen hin sch&alsr vfsrdsnd in gleicher Weise konisch ausgebildet sind und die zur Sohle der Ausnehmungen gewandte Seite des Rastnockens in Raetstellung einen Abstand von der Sohle der Ausnehmungen aufweist und der Obergang zwischen den Seitenflächen und der zur Sohle der Ausnehmungen geewandten Seite des Rastnockens gerundet ist.According to the invention, this object is achieved in that the latching recesses in the latching rail and the one engaging therein Latches to the sole of the recesses sch & alsr vfsrdsnd in are conical in the same way and the side of the locking cam facing the sole of the recesses is in the ratchet position is at a distance from the bottom of the recesses and the transition between the side surfaces and the side of the locking cam facing the bottom of the recesses is rounded.
Zweckmässigerweise ist der Rastnocken ein Stahlschmiedeteil und der Riegel ist um eine parallel zu den Gleitschienen verlaufende Achse im Lagerträger gelagert und der Rastnocken im Lagerträger axial spielfrei gehalten.The locking cam is expediently a forged steel part and the bolt is mounted in the bearing bracket about an axis running parallel to the slide rails and the locking cam is held axially free of play in the bearing bracket.
Die neuerungsgemäße Feststellvorrichtung für Gleitschienenführungen hat den Vorteil, da£ die vom Fahrzeugsitz in Verschieberichtung der Gleitschienenführung wirkenden Kräfte vomThe locking device according to the invention for slide rail guides has the advantage that the forces acting from the vehicle seat in the direction of displacement of the slide rail guide from
Riegel» spielfrei In die Rastschiene und von dort In den Fahrzeugboden übergeleitet werden und daß diese spielfreie Arretierung auch dann gewährleistet ist. wenn durch extrem hohe Belastungen oder infolge langer Betriebszeit die Rastausnehmungen in der Rastschiene ausschlagen. Der Konische Rastnocken fol^t unter der Kraft der Rückstellfeder den Verschleißerscheinungen in der Rastschiene und sichert somit eine spielfreie Verriegelung.Bolt »play-free into the locking rail and from there into the vehicle floor and that it is play-free Locking is also guaranteed. if by extremely high Loads or the locking recesses as a result of long operating times knock out in the locking rail. The conical locking cam fol ^ t under the force of the return spring the signs of wear in the locking rail and thus ensures a backlash-free locking.
In der folgenden Besehreibung ist unter Bezugnahme auf die Zeichnungen ein Ausführungsbeispiel der Erfindung näher erläutert. Die Zeichnungen zeigen inIn the following description, reference is made to the Drawings an embodiment of the invention explained in more detail. The drawings show in

Zwischen! den Flanschen der Ausseneohiene 1 und der Innensehiene 2 sind RoIl wälzkörper 3 angeor^et. Nach innen abgewinkelte Leisten 4 der C-förmigen Aussenschiene bilden mit nach aussen abgewinkelten Leisten 5 der Innenechiene 2 Kanäle» in denen zur seitlichen Führung Kunststoffgle?tkörper 6 angeordnet sind..The 01e.itseM # aeJifÖiiruitg consists of e.ii * e: egg-shaped rail 1 uöd eleven- la der Äuesjenateh ^ einiei 1, pelilufteii f rail 2 with a so-called hat profile. Between! the Flanges of the outer rail 1 and the inner rail 2 are RoIl rolling elements 3 angeor ^ et. Inwardly angled strips 4 of the C-shaped outer rails form with outwardly angled Bars 5 of the inner rail 2 channels »in those to the side Guide plastic slide 6 are arranged ..
Zum Feststellen der Gleitschienen 1 und 2 dient eine mit der ortsfesten Aussenschiene 1 verbundene Rastschiene 7, die mit in gleichen Abständen angeordnete Rastausnehmungen 8 versehen ist. In diese Rastausnehmungen greift ein Rastnocken 11 eines Riegels 1o ein, der in einem an der verschiebbaren Innenschiene 2 angeschweißten Lagerträger 9 um die Achse 13 schwenkbar gelagert ist. Eine Rückstellfeder 12 hält den Riegel 1o in Raststellung. Der Riegel 1o kann von Hand oder über eine Verstellvorrichtung gegen die Kraft der Rückstellfeder 12 nach oben verschwenkt werden und somit außer Eingriff mit der Rastschiene gebracht werden, so daß der Fahrzeugsitz parallel zu der Gleitschienenführung versteilt werden kann.To fix the slide rails 1 and 2, a latching rail 7 connected to the fixed outer rail 1, which is connected to in equally spaced locking recesses 8 is provided. A latching cam 11 engages in these latching recesses Bolt 1o, which is mounted pivotably about the axis 13 in a bearing bracket 9 welded to the displaceable inner rail 2 is. A return spring 12 holds the bolt 1o in the locking position. The latch 1o can be done by hand or using an adjustment device be pivoted upwards against the force of the return spring 12 and thus out of engagement with the locking rail be brought so that the vehicle seat can be steepened parallel to the slide rail guide.
Wie insbesondere Fig. 2 zeigt, sind die Rastausnehmungen zu ihrer Sohle 14 hin schmaler werdend konisch ausgebildet. In gleicher Weise ist auch der Rastnooken 11 konisch ausgebildet, jedoch ist er insgesamt etwas breiter, so daß die zur Sohle 14 gewandte Seite 15 des Rastnockens in Raststellung einen Abstand von der Sohle 14 aufweist.As FIG. 2 shows in particular, the latching recesses are conical in shape, becoming narrower towards their sole 14. In in the same way, the locking hook 11 is also conical, however, it is somewhat wider overall, so that the side 15 of the locking cam facing the sole 14 is spaced apart in the locking position of the sole 14.
Der als Stahlschmiedeteil ausgebildete Rastnocken 11 ist an beiden Seiten mit ringförmigen, die zylindrische Achse des Riegels to umgebende Bundflächen 16 versehen, an die Stirnflächen von hülsenförmigen die Achse des Riegels 1o beidseitig des Nockens 11 umgebende Teile 17 des Lagerträgers 9 anliegen. Auf diese Weise ist der Riegel 1o hoch belastbar und praktisch spielfrei im Lagerträger 9 gehalten.The latching cam 11, which is designed as a steel forged part, is annular on both sides, the cylindrical axis of the Bar to surrounding collar surfaces 16 provided, on the end faces of the sleeve-shaped the axis of the bar 1o on both sides of the cam 11 surrounding parts 17 of the bearing bracket 9 are in contact. In this way, the bolt 1o is highly resilient and held in the bearing bracket 9 with practically no play.
