Abstract
Description
Die Erfindung betrifft eine Vorrichtung, welche bei einem Fahrzeugsitz eine drehbare Ritzeleinheit und eine relativ zur Ritzeleinheit bewegliche und mit dieser in Zahneingriff stehende Zahnstange in definierter Relation zueinander hält.The The invention relates to a device which in a vehicle seat a rotatable pinion unit and a relative to the pinion unit movable and with this toothed rack in a defined Relation to each other.
Bekannte Vorrichtungen dieser Art, welche bei der Umsetzung einer Drehbewegung der Ritzeleinheit in eine lineare Bewegung der Zahnstange oder bei einer Abrollbewegung der Ritzeleinheit den Zahneingriff sicherstellen sollen, sind beispielsweise zwei Unterlegscheiben, welche von beiden Seiten der Zahnstange her auf die Ritzeleinheit geschoben, in Anlage mit der Zahnstange gebracht und mit der Ritzeleinheit durch eine Schraubverbindung verspannt sind.Known Devices of this kind, which in the implementation of a rotational movement the pinion unit in a linear movement of the rack or at a rolling movement of the pinion unit to ensure the meshing are, for example, two washers, which of both The sides of the rack are pushed onto the pinion unit, in abutment brought with the rack and with the pinion unit by a Screwed are clamped.
Die
Durch die Führungssicherungsvorrichtung, welche durch wenigstens teilweises Umschließen der Zahnstange den Zahneingriff zwischen der Ritzeleinheit und der Zahnstange sichert, steht eine einfach aufgebaute und einfach herzustellende Baugruppe zur Verfügung, die vorzugsweise zugleich weitere Funktionen erfüllen kann, beispielsweise indem sie die Zahnstange gegenüber der Ritzeleinheit führt und vorzugsweise zusätzlich in axialer Richtung der Ritzeleinheit sichert. Dies wird durch eine Lagerung der Führungssicherungsvorrichtung auf der Ritzeleinheit erreicht, beispielsweise auf wenigstens einem zylindrischen Abschnitt derselben. Mit der Abmessung der Führungssicherungsvorrichtung ist auch das Zahnflankenspiel zwischen der Zahnstange und der Ritzeleinheit vorgegeben.By the guide locking device, which by at least partially enclosing the rack the tooth engagement between the pinion unit and the rack secures, stands one simply constructed and easy to manufacture assembly available, the preferably at the same time can fulfill other functions, for example by they are facing the rack the pinion unit leads and preferably in addition secures in the axial direction of the pinion unit. This is done by a Storage of the guide locking device reached on the pinion unit, for example, at least one cylindrical section of the same. With the dimension of the guide locking device is also the backlash between the rack and pinion unit specified.
Zur Reduktion der Anzahl der Bauteile und damit zugleich zur Verringerung des Montageaufwands und zur Reduktion der Herstellungskosten weist die Führungssicherungsvorrichtung einen Führungskäfig, welcher die Zahnstange von vier Seiten umschließt, und ein mit einem Gewinde versehenes Sicherungselement, beispielsweise eine Mutter oder eine Schraube, auf, welches am Führungskäfig anliegt und mit der Ritzeleinheit in Schraubeingriff steht. Die Führung der Zahnstange wird vorzugsweise verbessert, indem der Führungskäfig auf der Innenseite Führungsflanken aufweist, welche seitlich an der Zahnstange anliegen.to Reduction in the number of components and thus at the same time for reduction the assembly costs and to reduce the production costs the guide locking device a guide cage, which the rack encloses from four sides, and one with a thread provided fuse element, such as a mother or a Screw on, which rests on the guide cage and is in screw engagement with the pinion unit. The leadership of Rack is preferably improved by the guide cage on the inside guide flanks has, which rest laterally on the rack.
Die Führungssicherungsvorrichtung kann anstelle des Führungskäfigs ein Langlochblech, d.h. ein Blech mit einem Langloch, aufweisen, welches einen Zapfen der Ritzeleinheit umschließt, auf welchem das Blech gelagert ist, und welches die Zahnstange beispielsweise nur von drei Seiten umschließt. Es sind weitere Lösungen, wie Andrückrollen, Andrückbolzen, feststehende Brückenbleche oder dergleichen denkbar.The Lead security device can in place of the guide cage Long hole sheet, i. a plate with a slot, have, which encloses a pin of the pinion unit, on which the sheet is mounted is, and which the rack, for example, only from three sides encloses. There are other solutions like pressure rollers, pressure bolt, fixed bridge plates or the like conceivable.
Die Führungssicherungsvorrichtung kann bei vielen Antrieben verwirklicht sein, beispielsweise bei einem Antrieb eines Höheneinstellers, welcher wiederum einen Teil eines Fahrzeugsitzes bildet.The Lead security device can be realized in many drives, for example, at one Drive a height adjuster, which in turn forms part of a vehicle seat.
