Der Erfindung liegt die Aufgabe zugrunde, eine Verstelleinrichtung für einen Kraftfahrzeugsitz zu schaffen, die bei einfacher Herstellung geeignet ist, ein großes Drehmoment zu übertragen.Of the Invention is based on the object, an adjustment for a To provide a motor vehicle seat which is suitable for simple production, a big Transmit torque.
Diese Aufgabe wird mit der Verstelleinrichtung mit den Merkmalen des Patentanspruchs 1 gelöst.These Task is with the adjustment with the features of the claim 1 solved.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.advantageous Embodiments of the invention are specified in the subclaims.
Dem Anspruch 2 zufolge soll das Innenelement drei in Bezug auf die Klemmbahn des Außenringes sehnenförmig unter gleichem Winkel zueinander verlaufende Schenkel aufweisen, die jeweils über einen der Klemmbahn angepaßten Führungsradius ineinander übergehen. Das Innenelement ist bezüglich seiner Außenkontur demnach insgesamt ein gleichseitiges Dreieck, wobei dessen Spitzen, angepaßt an den Führungsradius des Außenrings, abgerundet sind. Auf diese Weise ergibt sich eine besonders günstige Abstützung zwischen dem Innenelement und dem Außenring, wobei gleichzeitig im Bauraum von Innenelement und Außenring die Stellglieder mit ihren Mitnehmern angeordnet sein können.the According to claim 2, the inner element should be three with respect to the clamping track of the outer ring chordally have thighs running at the same angle to one another, each over one of the clamp track adapted Leader radius merge. The inner element is with respect to his outer contour therefore an equilateral triangle, with its tips, customized to the guide radius the outer ring, are rounded. In this way, a particularly favorable support between the inner element and the outer ring, at the same time in the space of inner element and outer ring the actuators can be arranged with their drivers.
Weiterhin soll nach Anspruch 3 von jedem Schenkel aus radial nach außen ein Abschnitt mit rechteckiger Kontur verlaufen, der gegenüber dem Außenring die rampenförmigen Klemmbahnen und die Anschlagflächen bildet. Ein derart gestaltetes Innenelement bedarf nur eines geringen fertigungstechnischen Aufwands.Farther should according to claim 3 of each leg from a radially outward Section with a rectangular contour, which is opposite the outer ring the ramp-shaped Clamps and the stop surfaces forms. Such a designed inner element requires only a small production engineering effort.
Eine gemäß Anspruch 4 aus einem lippenförmigen Elastomerprofil hergestellte, beispielsweise als Gummiprofil ausgeführte Druckfeder läßt sich in besonders günstiger Weise in dem Zwischenraum zwischen den Abschnitten mit rechteckiger Kontur und der Klemmbahn des Außenrings anordnen, wobei sie im Gegensatz zu einer Schraubenfeder keinerlei Klappergeräusche verursacht. Dieses lippenförmige Gummiprofil steht als Meterware zu einem sehr günstigen Preis zur Verfügung.A produced according to claim 4 from a lip-shaped elastomer profile, for example, designed as a rubber compression spring can be arranged in a particularly favorable manner in the space between the sections with a rectangular contour and the clamping track of the outer ring, where In contrast to a coil spring causes no rattling noises. This lip-shaped rubber profile is available by the meter at a very reasonable price.
Zur weiteren Erläuterung der Erfindung wird auf die Zeichnung verwiesen, in der ein Ausführungsbeispiel vereinfacht dargestellt ist.to further explanation The invention is directed to the drawing, in which an embodiment is shown simplified.
