Bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Preferred embodiments of the invention result from the subclaims.

Nachstehend werden zwei bevorzugte Ausführungsformen der Erfindung anhand der Zeichnungen im einzelnen beschrieben. Es zeigen:Two preferred embodiments of the Invention described with reference to the drawings. Show it:

Fig. 1 - eine perspektivische Darstellung der Sitztie­ fenverstellvorrichtung mit manueller Betäti­ gung; Fig. 1 - a perspective view of the Sitztie fenverstellvorrichtung with manual actuation;

Fig. 2 - eine perspektivische Darstellung der Sitztie­ fenverstellvorrichtung mit motorischer Betäti­ gung. Fig. 2 - a perspective view of the Sitztie fenverstellvorrichtung with motorized actuation.

Die Sitztiefenverstellvorrichtung 1, im folgenden mit Sitz­ tiefenverstellbereich bezeichnet, weist ein Trägerelement 1b auf, das mit Führungsleisten 1a in Führungsnuten 2b am Sitzrahmen 2 längsverschieblich geführt ist. Parallel zu den Führungsnuten 2b sind am Sitzrahmen 2 einander gegen­ überliegende, als Zahnstangen ausgebildete Gegenstücke 2a, im folgenden mit Gegenbereiche bezeichnet, vorgesehen, in die als Stirnzahnräder ausgebildete Räder 3 eingreifen. Die Räder 3 sind an senkrecht zur Führungsebene des Trägerele­ ments 1b verlaufenden Drehachsen 3a am Trägerelement 1b ge­ lagert. Mit den äußeren Rädern 3 kämmen Zwischenräder 4, die miteinander in Eingriff stehen und sich um zu den Dreh­ achsen 3a parallele Drehachsen 4a drehen. Über diese Zwi­ schenräder 4 sind die beiden äußeren Räder 3 schlupffrei gekoppelt.The seat depth adjustment device 1, called depth adjusting section below with the seat, has a carrier element 1 b, which is provided with guide rails 1 b a 2 in guide grooves longitudinally displaceably guided on the seat frame. 2 Parallel to the guide grooves 2 b are provided on the seat frame 2 against each other opposite, designed as racks counterparts 2 a, hereinafter referred to as counter areas, in which engage as wheels 3 designed as spur gears. The wheels 3 are on perpendicular to the guide plane of the Trägerele element 1 b extending axes of rotation 3 a on the carrier element 1 b ge. With the outer wheels 3 mesh intermediate wheels 4 , which are in engagement with each other and rotate about the axes of rotation 3 a parallel axes of rotation 4 a. About these inter mediate wheels 4 , the two outer wheels 3 are coupled slip-free.

In eines der Räder 4 greift ein Raststück 5a, im folgenden mit Rastbereich bezeichnet, ein, der an einem Griffstück 5, im folgenden mit Griffbereich bezeichnet, angeordnet ist. Der Rastbereich 5a ist als Zahnsegment ausgebildet, wenn das Rad 4 ein Zahnrad ist. Der Griffbereich 5 ist an dem Trägerelement 1b befestigt und um eine Achse 5d schwenkbar. Der als Hebel ausgebildete Griffbereich 5 trägt eine Rück­ stellfeder 5b, die sich an einem Gegenlager 5c am Trägere­ lement 1b abstützt. Die Rückstellfeder 5b hält den Rastbe­ reich 5a mit dem Zwischenrad 4 in Eingriff und verhindert dadurch die Verschiebung des Sitztiefenverstellbereichs 1 gegenüber dem Sitzrahmen 2, solange der Griffbereich 5 nicht ausgeschwenkt ist.In one of the wheels 4 , a locking piece 5 a, hereinafter referred to as the locking area, engages, which is arranged on a handle 5 , hereinafter referred to as the handle area. The locking area 5 a is designed as a toothed segment when the wheel 4 is a toothed wheel. The grip area 5 is fastened to the carrier element 1 b and can be pivoted about an axis 5 d. Designed as a lever handle portion 5 transmits a return spring 5 b, c located on a thrust bearing 5 at Slower lement bears 1 b. The return spring 5 b holds the Rastbe rich 5 a with the intermediate wheel 4 in engagement and thereby prevents the displacement of the seat depth adjustment area 1 relative to the seat frame 2 as long as the grip area 5 is not pivoted out.

Nachdem der Rastbereich 5a durch Ausschwenken des Griffbe­ reichs 5 von dem Zwischenrad 4 abgehoben worden ist, kann der Sitztiefenverstellbereich 1 verschoben werden. Wenn der Sitztiefenverstellbereich 1 in Richtung des Pfeils 6 ver­ schoben wird, wälzen sich die Räder 3 auf den Gegenberei­ chen 2a gegenläufig mit den Drehrichtungen 3b und 3c ab. Die mit ihnen und miteinander kämmenden Zwischenräder 4, die sich zwangsläufig in den Drehrichtungen 4b und 4c dre­ hen müssen, bewirken, daß die äußeren Räder 3 sich nur um gleiche Winkelbeträge drehen können. Dadurch wird das Verkanten der Führungsleisten 1a in den Führungsnuten 2b verhindert.After the locking area 5 a has been lifted by pivoting the Griffbe range 5 from the intermediate wheel 4 , the seat depth adjustment area 1 can be moved. If the seat depth adjustment area 1 is pushed ver in the direction of arrow 6 , the wheels 3 roll on the opposite areas 2 a in opposite directions with the directions of rotation 3 b and 3 c. The intermeshing with them and each other intermediate wheels 4 , which must inevitably in the directions of rotation 4 b and 4 c hen, cause that the outer wheels 3 can only rotate by the same angular amounts. This prevents the guide rails 1 a from tilting in the guide grooves 2 b.

Bei der in Fig. 2 dargestellten, motorischen Verstellung des Sitztiefenverstellbereichs 1 sind die Räder 3 und die Zwischenräder 4 identisch zur vorhergehenden Ausführungs­ form gemäß Fig. 1 angeordnet. In eines der Zwischenräder 4 greift ein als Schneckenrad ausgebildetes Getrieberad 5e ein, das am Griffbereich 5' drehbar gelagert ist. Das Ge­ trieberad 5e wird durch eine flexible Welle 5f von einem nicht dargestellten Antriebsmotor angetrieben, der an vom Sitztiefenverstellbereich 1 entfernter Stelle des Fahrzeug­ sitzes angeordnet sein kann. Das Getrieberad 5e wird durch eine Rückstellfeder 5b mit dem Zwischenrad 4 in Eingriff gehalten, die an dem um die Achse 5d schwenkbaren Griffbe­ reich 5' vorgesehen ist.In the motorized adjustment of the seat depth adjustment region 1 shown in FIG. 2, the wheels 3 and the intermediate wheels 4 are arranged identically to the previous embodiment according to FIG. 1. A gear wheel 5 e, which is designed as a worm wheel and engages rotatably on the grip area 5 ′, engages in one of the intermediate wheels 4 . The Ge gear wheel 5 e is driven by a flexible shaft 5 f by a drive motor, not shown, which can be arranged at a remote location from the seat depth adjustment area 1 of the vehicle seat. The gear wheel 5 e is held by a return spring 5 b with the intermediate wheel 4 , which is provided on the 5 d pivotable about the axis Griffbe rich 5 '.

Durch die federbetätigte Getriebeverbindung wird eine Über­ lastung der Mechanik des Sitztiefenverstellbereichs 1 bei Hindernissen im Verschiebeweg vermieden. Die Verstellung des Sitztiefenverstellbereichs 1 ist im Notfall auch von Hand möglich. Die bis auf den Griffbereich 5; 5' identische Ausführung des motorisch verstellbaren Sitztiefenverstell­ bereichs mit dem manuell verstellbaren, verbilligt darüber­ hinaus die Herstellung.The spring-actuated gear connection prevents an overload of the mechanics of the seat depth adjustment area 1 in the event of obstacles in the displacement path. The adjustment of the seat depth adjustment area 1 is also possible by hand in an emergency. The except for the grip area 5 ; 5 'identical design of the motor-adjustable seat depth adjustment area with the manually adjustable, also reduces the cost of manufacture.
