Abstract
Description
Die Erfindung betrifft einen Kraftfahrzeugsitz nach dem Oberberiff des Schutzanspruchs 1.The The invention relates to a motor vehicle seat according to the Oberberiff of Protection claim 1.
Eine
Sitzhöhenverstellung
der als bekannt vorausgesetzten Art (
Es
sind bisher lediglich spielfreie Neigungsverstellbeschläge für Rückenlehnen
bekannt (
Derartige Neigungsverstellbeschläge sind als Taumelgetriebe mit einander umschließenden Verzahnungen unterschiedlicher Zähnezahlen ausgebildet. Zur Spielbeseitigung sind die Innenverzahnung und die darin eingreifende Außenverzahnung konisch ausgebildet und in Axialrichtung gegeneinander vorgespannt. Derartige Neigungsverstellbeschläge sind weder in ihrem Aufbau noch in ihrer Wirkungsweise mit Höhenverstellvorrichtungen der als bekannt vorausgesetzten Art vergleichbar.such Neigungsverstellbeschläge are different as a wobble gear with each other enclosing gears number of teeth educated. To remedy the game are the internal teeth and the engaging external teeth tapered trained and biased against each other in the axial direction. such Neigungsverstellbeschläge are neither in their construction nor in their operation with height adjustment devices the comparable known as known type.
Zur Vermeidung eins Spiels in einem Getriebezug ist es auch bereits bekannt (GB 2 244 538 A), zwischen einem Antriebsritzel und einem Abtriebsritzel eines Getriebezugs ein in axialer Richtung verschiebliches und vorgespanntes Zwischenritzel anzuordnen und die Flanken der Zähne sämtlicher Ritzel konisch zu deren Drehachsen anzuordnen. Ein solcher Getriebezug ist aufwendig und zur Verwendung bei einem Kraftfahrzeugsitz mit Sitzhöhenverstellung ungeeignet.to Avoiding a game in a gear train is already there known (GB 2 244 538 A), between a drive pinion and a Output pinion of a gear train a displaceable in the axial direction and biased intermediate pinion and the flanks of the Teeth of all Pinion conical to arrange their axes of rotation. Such a gear train is complicated and for use in a motor vehicle seat with Seat height adjustment not suitable.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, bei einem Kraftfahrzeugsitz der als bekannt vorausgesetzten Art die Höhenverstellvorrichtung spielfrei und geräuscharm zu halten.outgoing From this prior art, the invention is based on the object in a motor vehicle seat of the type assumed to be known the height adjustment device free of play and quiet to keep.
Die Lösung dieser Aufgabe erfolgt mit den Merkmalen des Schutzanspruchs 1.The solution This object is achieved with the features of the protection claim. 1
Bei der vorgeschlagenen Lösung bleibt die Höhenverstellvorrichtung auch bei Veränderungen der Zahneingriffsverhältnisse und bei Verschleiß dauerhaft spielfrei.at the proposed solution remains the height adjustment device even with changes in the Tooth engagement conditions and in case of wear permanently play.
Ein Verzwängen der beteiligten Verzahnungen kann nicht auftreten. Die Vorspannung kann ausreichend so bemessen werden, daß die Höhenverstellvorrichtung nicht schwergängig wird.One Verzwängen The involved gears can not occur. The bias can be sufficiently dimensioned that the height adjustment is not sluggishly becomes.
Bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.preferred Embodiments of the invention will become apparent from the dependent claims.
Nachstehend wird eine bevorzugte Ausführungsform der Erfindung anhand der Zeichnungen im einzelnen beschrieben. Es zeigen:below becomes a preferred embodiment of the invention with reference to the drawings described in detail. It demonstrate:
Ein
Kraftfahrzeugsitz, von dem in
Der
verzahnte Bereich des Antriebsritzels
Das
Antriebsritzel
Ein
Abtriebsrad des Gesperres
Die
Druckfeder
Statt der konischen Ausbildung der Hüllfläche der Verzahnung ist auch deren kreiszylindrische Ausbildung möglich. Es müssen dann die Flanken der Zähne des Antriebsritzels konisch zu dessen Drehachse verlaufen, während jedoch der Kopfkreis über die gesamte Zahnbreite gleich bleibt.Instead of the conical formation of the envelope of the Gearing is also their circular cylindrical design possible. It have to then the flanks of the teeth of the drive pinion tapered to the axis of rotation, while, however the head circle over the entire tooth width remains the same.
