Abstract
Description
Die vorliegende Erfindung betrifft eine Verstelleinheit eines Kraftfahrzeugsitzes mit einem Verstellhebel gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates to an adjustment unit of a motor vehicle seat with an adjusting lever according to the preamble of claim 1
Verstelleinheiten
dieser Art sind z. B. in
Bei Verstelleinheiten gattungsgemäßer Art ist der Verstellhebel zur Drehmomentübertragung direkt und starr mit dem Verstellmittel verbunden. Daher müssen alle sich quer zur Betätigungsrichtung des Verstellhebels einstellenden Toleranzen, nämlich die aus dem Verstellmittel, die aus dem Bauteil, mit dem das Verstellmittel verbunden ist, die aus der Blende und ihrer Halterung sowie die Toleranzen aus dem Verstellhebel selbst über die Schlitzbreite in der Blende berücksichtigt werden. Dieser Schlitz soll aber auch designerischen Gründen sehr schmal ausgeführt werden. Ein schmaler Blendenschlitz kann aufgrund der oben angesprochenen Toleranzen dazu führen, dass der Verstellhebel sich in dem Schlitz verklemmt. Im Falle einer Höhenverstelleinheit würde dann eine Bremse dieser Einheit eventuell nicht mehr richtig geschlossen werden und der Sitz bei einem Crash nach unten durchlaufen.at Adjustment units of the generic type the adjusting lever for torque transmission directly and rigidly connected to the adjusting means. Therefore, everyone must transverse to the direction of actuation of the Adjusting lever adjusting tolerances, namely from the adjustment, from the component, with which the adjusting means is connected, the from the aperture and its holder as well as the tolerances from the Lever itself over the slot width in the aperture are taken into account. This slot but should also be designerischen reasons very narrow become. A narrow aperture slot may be due to the above Cause tolerances that the adjusting lever jammed in the slot. In case of a Height adjustment then would a brake of this unit may not be closed properly go through and the seat in a crash down.
Aufgabe der vorliegenden Erfindung ist es daher, für eine Verstelleinheit gattungsgemäßer Art eine Lösung zur Verfügung zu stellen, die bei schmalem Blendenschlitz die Funktionalität der Verstelleinheit nicht beeinträchtigt.task The present invention is therefore, for an adjustment unit of the generic type a solution to disposal to provide, with a narrow aperture slot, the functionality of the adjustment not impaired.
Diese Aufgabe wird erfindungsgemäß mit einer Verstelleinheit eines Kraftfahrzeugsitzes gelöst, die die Merkmale des Patentanspruchs 1 aufweist.These Task is according to the invention with a Adjustment of a motor vehicle seat solved, the features of the claim 1 has.
Bei der erfindungsgemäßen Lösung ist der Verstellhebel nicht mehr direkt und starr mit der Verstelleinheit verbunden, sonder indirekt und flexibel, wodurch im Zusammenspiel mit der linienförmigen Gleitlagerung des Verstellhebels unmittelbar vor dem Schlitz Toleranzen zwischen der Höhenverstelleinheit und der Blende kompensiert werden können, und zwar in Maß und Winkel. Dadurch wird eine schmale Schlitzausführung an der Blende, ohne ein Klemmen des Verstellhebels befürchten zu müssen, möglich.at the solution according to the invention the adjusting lever is no longer directly and rigidly with the adjusting unit connected, but indirectly and flexibly, thereby interacting with the linear slide bearing of the adjusting lever immediately before the slot tolerances between the height adjustment unit and the aperture can be compensated, in measure and angle. This will result in a narrow slot design on the bezel without one Fearing terminals of the adjusting lever to have to, possible.
In weiterer Ausgestaltung der Erfindung stellt ein Käfig eine Drehmomentübertragung vom Verstellhebel auf das Verstellmittel sicher und punktförmige Lager für das erste Ende des Verstellhebels zur Verfügung. Schrägstellungen des Verstellhebels aufgrund von Toleranzen zwischen dem Verstellmittel und der Blende wirken sich im Schlitz der Blende aufgrund der unmittelbar vorgelagerten parallelen linienförmigen Gleitführung des Verstellhebels kaum aus. Das gilt um so mehr, je größer der Abstand zwischen der Punktlagerung des ersten Endes des Verstellhebels und der Linienlagerung des zweiten Endes des Verstellhebels ist. Aufgrund der Lagerung seines ersten und zweiten Endes quer zu seiner Betätigungsrichtung hat der Verstellhebel eine bessere Lagestabilität in dieser Richtung.In Another embodiment of the invention provides a cage torque transmission from the adjusting lever on the adjustment safe and punctual bearing for the first end of the lever available. Inclinations of the adjusting lever due to tolerances between the adjustment means and the aperture affect the slot of the aperture due to the immediately upstream parallel line-shaped slide barely off the lever. This is even more true, the larger the Distance between the point bearing of the first end of the adjusting lever and the line bearing of the second end of the adjusting lever is. Due to the storage of his first and second end across his actuation direction the lever has a better positional stability in this direction.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den übrigen Unteransprüchen.Further advantageous embodiments of the invention will become apparent from the other dependent claims.
