Description
Die Erfindung betrifft eine Fahrzeugsitzverstellvorrichtung mit mindestens einer flexiblen Welle, die vorzugsweise zur Sitzlängsverstellung, eingesetzt werden kann.The The invention relates to a vehicle seat adjustment device with at least a flexible shaft, preferably for seat longitudinal adjustment, can be used.
Fahrzeugsitze weisen im Allgemeinen mehrere Verstellfunktionen auf, die zumindest bei höherpreisigen Fahrzeugen elektromotorisch realisiert werden. Die Kraftübertragung von den Elektromotoren auf die Getriebe bzw. Verstellmechanismen erfolgt hierbei über flexible Wellen, die unter bzw. im Sitz verlegt sind. Durch die flexiblen Wellen können einbauabhängige Toleranzen und Erschütterungen kompensiert werden.car seats generally have several adjustment functions, at least at higher priced Vehicles are realized by electric motor. The power transmission from the electric motors to the gearboxes or adjusting mechanisms takes place via flexible shafts that are laid under or in the seat. By the Flexible shafts can be installation-dependent tolerances and shakes compensated become.
Die
Die
Durch derartige Maßnahmen können im Allgemeinen baubedingte Toleranzen und einwirkende Schläge aufgefangen bzw. gedämpft werden. Es zeigt sich jedoch, dass weiterhin eine erhebliche Schallübertragung von dem Motor über die Welle und die Verstelleinrichtung auf den Fahrzeugsitz erfolgt, die von dem Benutzer als störend empfunden wird.By such measures can In general, building-related tolerances and impacts are absorbed or steamed become. It turns out, however, that continues to be a significant sound transmission from the engine over the shaft and the adjustment takes place on the vehicle seat, the from the user as annoying is felt.
Der Erfindung liegt die Aufgabe zu Grunde, eine Fahrzeugsitzverstellvorrichtung mit mindestens einer flexiblen Welle zu schaffen, die kleinbauend und kostengünstig herstellbar ist und eine Verringerung der Schallübertragung ermöglicht.Of the Invention is based on the object, a Fahrzeugsitzverstellvorrichtung with at least one flexible shaft to create, the small and economical can be produced and a reduction of the sound transmission allows.
Diese Aufgabe wird durch eine Fahrzeugsitzverstellvorrichtung mit mindestens einer flexiblen Welle nach Patentanspruch 1 gelöst. Die Unteransprüche beschreiben bevorzugte Weiterbildungen.These Task is by a vehicle seat adjuster with at least a flexible shaft solved according to claim 1. Describe the dependent claims preferred developments.
Erfindungsgemäß ist die flexible Welle somit im Wesentlichen geradlinig ausgebildet mit zwei in ihrer Wellenachse angeordneten, starren Anschlussstangen, die in den Motor und in die Verstelleinrichtung bzw. das Getriebe eingesetzt werden, und einem mittleren, flexiblen Verbindungsteil aus einem Elastomer, das die beiden Anschlussstangen in entsprechenden Aufnahmen drehsteif aufnimmt und sich in radialer Richtung über die Anschlussstangen hinaus erstreckt. Die Anschlussstangen sind erfindungsgemäß somit nicht direkt miteinander in Kontakt, sondern in axialer Richtung über eine freie Länge voneinander getrennt. Die Drehmomentübertragung findet somit von der vorderen Anschlussstange aus nur über das mittlere Verbindungsteil auf die hintere Anschlussstange statt. Eine direkte Übertragung von Körperschallwellen über die vorzugsweise metallischen Anschlussstangen kann somit wirksam unterbunden werden. Hierbei wird ausgenutzt, dass das Ver bindungsteil, das eine flexible Nachgiebigkeit bei Biegebeanspruchung ermöglicht, gleichzeitig auch eine die Körperschallwellen entkoppelnde, vorzugsweise dämpfende, Wirkung aufweist.According to the invention flexible shaft thus substantially rectilinear with two rigid connecting rods arranged in their shaft axis, in the engine and in the adjustment or the transmission be used, and a middle, flexible connection part made of an elastomer that holds the two connecting rods in place Record torsionally stiff and in the radial direction over the Extends connecting rods out. The connecting rods are thus according to the invention not directly in contact with each other, but in the axial direction over a free length separated from each other. The torque transmission thus takes place the front connecting rod from only over the middle connecting part on the rear connecting rod instead. A direct transfer of Structure-borne sound waves over the preferably metallic connecting rods can thus effectively prevented become. This exploits that the Ver binding part, the one allows flexible compliance with bending stress, at the same time also the structure-borne sound waves decoupling, preferably damping, Has effect.
Ein wesentlicher Gegenstand der Erfindung ist weiterhin die gesamte Fahrzeugsitzverstellvorrichtung mit einem zwischen den Sitzschienen angeordneten Motor, zwei an den beiden Sitzschienen angeordneten Abtriebseinheiten und zwei erfindungsgemäßen, flexiblen, geradlinig verlaufenden Wellen zwischen dem Motor und den Abtriebseinheiten.One essential object of the invention is also the entire Vehicle seat adjuster with one between the seat rails arranged motor, two arranged on the two seat rails Output units and two according to the invention, flexible, straight extending waves between the engine and the output units.
Erfindungsgemäß wird somit eine kompakte, platzsparende Anordnung geschaffen, die die Übertragung von Körperschallwellen verhindert, kleinbauend und kostengünstig ist.Thus, according to the invention a compact, space-saving arrangement created that the transmission of structure-borne sound waves prevents, is small-scale and inexpensive.
