Description

Verstellvorrichtung für Kraftfahrzeugsitze Die Erfindung betrifft eine Verstellvorrichtung für Kraftfahrzeugsitze. Bei Vorrichtungen zum Lagern längsverschiebbarer, ein- und feststellbarer Kraftfahrzeugsitze auf dem Fahrzeugboden sind Anordnungen mit zwei U-förmigen, an den offenen Seiten mit angewinkelten Enden unter Zwischenschalten von Kugeln ineinandergreifenden Schienen bekanntgeworden, die zwischen sich Lagerkugeln einschließen, über die die Schienen sich gegeneinander längsverschieblich abstützen. Sind zwischen zwei Schienen lediglich zwei Lagerkugeln vorhanden, so steigen die Punktbelastungen zwischen diesen Kugeln und der Schiene an, so daß bei sehr hohen Belastungen die Möglichkeit eines Eindrückens der Kugeln in die Schienenoberfläche nicht ausgeschlossen ist. Eine bekannte Vorrichtung vermeidet diese Mängel durch Einlegen von Federstahlbändern zwischen die Kugeln und den Boden der Schienen, die ein derartiges Eindrücken verhindern und gleichzeitig eine gute Laufbahn für die Kugeln bilden. Bei dieser bekannten Anordnung sind die Federstahlbänder durch Niete mit den Schienen verbunden, und jedes Band, das sich über die gesamte Länge einer derartigen Schiene erstreckt, weist in der Mitte eine nach dem Schienenboden zugewandte, querverlaufende und nockenartige Eindrückung auf, so daß die Federeinlage in zwei Hälften geteilt wird, die an den Enden am Boden anliegen und nach der Mitte zu ansteigen.Adjusting device for motor vehicle seats The invention relates to an adjustment device for motor vehicle seats. In the case of devices for storing longitudinally displaceable, adjustable and lockable motor vehicle seats on the vehicle floor are arrangements with two U-shaped ends with angled ends on the open sides with interposition became known of balls interlocking rails with bearing balls between them include, over which the rails support each other longitudinally displaceable. If there are only two bearing balls between two rails, the will increase Point loads between these balls and the rail, so that at very high Loads the possibility of the balls pressing into the rail surface is not excluded. A known device avoids these shortcomings Insertion of spring steel strips between the balls and the bottom of the rails that prevent such indentations and at the same time ensure a good career for the Form balls. In this known arrangement, the spring steel strips are riveted connected to the rails, and each tape that extends the entire length of a such a rail, has in the middle a facing towards the rail floor, transverse and cam-like indentation, so that the spring insert in two Halves are divided, which lie at the ends on the floor and rise towards the middle.

Diese Anordnung hat den Nachteil, daß einerseits sowohl die Nietbefestigung als auch die Herstellung der besonders geformten Federbänder umständlich und teuer ist und den Schienenquerschnitt schwächt und andererseits in den Endstellungen der Kugeln keine Federwirkung erzielt wird. Außerdem muß, wenn die Kugelwege in den Schienen erheblich kürzer als die Hälfte der Schienenlänge sind, der an sich von den Kugeln nicht beanspruchte Mittelteil trotzdem mit einer Federstahleinlage versehen sein. Schließlich werden bei langen, etwa der Hälfte der Schienenlängen entsprechenden Verschiebewegen die Federbänder in ihrem Mittelteil so stark beansprucht, daß sie bleibend verformt werden oder gar zu Bruch gehen.This arrangement has the disadvantage that on the one hand both the rivet fastening as well as the production of the specially shaped spring strips laborious and expensive is and weakens the rail cross-section and on the other hand in the end positions of the Balls no spring effect is achieved. In addition, if the ball paths in the Rails are considerably shorter than half the rail length, which is in itself of The central part, which is not stressed by the balls, is nevertheless provided with a spring steel insert be. Finally, if the rail is long, about half the length of the rail will be appropriate Shifting the spring strips in their middle part is so heavily stressed that they be permanently deformed or even break.

Diese Nachteile werden durch die Erfindung in einfacher Weise dadurch beseitigt, daß als Federstahleinlage ein gerades Federstahlband verwandt wird, das lediglich im Querschnitt gewölbt und mit seiner konvexen Seite gegen die Kugeln gerichtet ist, wobei in weiterer Ausbildung der Erfindung und im Gegensatz zu der bekannten Ausführung das Federstahlband in der Schiene dadurch festgelegt wird, daß das Band zwischen die Begrenzungsanschläge für die Kugeln eingelegt oder eingeschoben wird.These disadvantages are alleviated by the invention in a simple manner eliminates the fact that a straight spring steel band is used as the spring steel insert, the only arched in cross-section and with its convex side against the balls is directed, wherein in a further embodiment of the invention and in contrast to the known design the spring steel band is fixed in the rail by that the tape is inserted or pushed in between the limit stops for the balls will.

Die Erfindung ist an Hand eines Ausführungsbeispiels schematisch und schaubildlich sowie zum Teil aufgebrochen dargestellt. Es zeigt Abb. 1 die Anordnung von Führungsschienen mit eingelegten Kugeln und Stahlfederband, Abb. 2 und 3 Schnitte nach den Linien II-II und III-III in Abb. 1.The invention is schematic and based on an exemplary embodiment shown diagrammatically and partially broken away. Fig. 1 shows the arrangement of guide rails with inserted balls and steel spring band, Fig. 2 and 3 sections according to lines II-II and III-III in Fig. 1.

Die untere U-Schiene 1 mit den Beschlägen 2 zur Verankerung im Fahrzeugboden führt in ihren angewinkelten Schenkelenden 3 die obere, an den Sitz anzubringende U-Schiene 4 der Sitzverstellvorrichtung mit deren angewinkelten Schenkelenden. Die beiden Schienen werden durch Kugeln 5 geführt, die zwischen den Schenkelenden 3 der Schienen 1 und 4 angeordnet sind, während zwischen ihnen eingeschlossene Lagerkugeln 6 das Gewicht des Sitzes übertragen.The lower U-rail 1 with the fittings 2 for anchoring in the vehicle floor leads in its angled leg ends 3 the upper to be attached to the seat U-rail 4 of the seat adjustment device with the angled leg ends. the Both rails are guided by balls 5, which between the leg ends 3 the rails 1 and 4 are arranged, while bearing balls trapped between them 6 transfer the weight of the seat.

Auf die innere, untere Fläche der unteren Profilschiene 1 ist ein einfaches, gerades, im Querschnitt gewölbtes Federstahlband 7 mit der erhabenen Seite nach oben zwischen die Begrenzungsanschläge 8 für die Lagerkugeln 6 so eingelegt, daß es von den Lagerkugeln beim Betätigen der Sitzverstellvorrichtung nicht mitgenommen werden kann.On the inner, lower surface of the lower profile rail 1 is a simple, straight, in cross-section arched spring steel strip 7 with the raised Side up between the limit stops 8 for the bearing balls 6 so inserted, that it is not taken along by the bearing balls when the seat adjustment device is operated can be.
