Abstract
Description
Die vorliegende Erfindung betrifft eine Verstellvorrichtung eines Kraftfahrzeugsitzes gemäß dem Oberbegriff des Anspruchs 1.The The present invention relates to an adjustment device of a motor vehicle seat according to the generic term of claim 1.
Eine
derartige Verstellvorrichtung ist in der
Der Aufbau von hinterer und vorderer Verstellvorrichtung ist prinzipiell gleich. Nachstehend wird daher nur die hintere Verstellvorrichtung weiter beschrieben.Of the Construction of the rear and front adjusting device is in principle equal. Hereinafter, therefore, only the rear adjusting device further described.
Das Ritzel kämmt mit einem Zahnsektor, der drehfest auf einem Querrohr sitzt, welches beide Seitenteile des Sitzteils miteinander verbindet und drehbar in diesen gelagert ist. Der Zahnsektor ist einstückig mit dem zugeordneten Lenker der Höhenverstellung ausgebildet, so dass das Querrohr gleichzeitig das obere Drehgelenk des hinteren Lenkers bildet. Die Zähne des Zahnsektors liegen auf einer Kreislinie um die Drehachse des Querrohres.The Pinion meshes with a tooth sector, which sits non-rotatably on a cross tube which connects both side parts of the seat part and rotatable stored in these. The tooth sector is integral with the associated handlebar the height adjustment formed, so that the cross tube at the same time the upper hinge the rear handlebar forms. The teeth of the toothed sector lie on a circular line around the axis of rotation of the cross tube.
Um im Crash-Fall zu verhindern, dass das Ritzel außer Eingriff mit dem Zahnsektor kommt, ist eine Klammer für das Ritzel vorgesehen, durch die es axial am Zahnsektor festgelegt ist. Diese besteht aus zwei Platten, die an ihren dem Zahnsektor abgewandten Enden außerhalb des Zahnsektors an zwei Flanschen aneinander liegen und dort miteinander vernietet sind. Nach den beiden Flanschteilen sind Absätze in den beiden Platten vorgesehen, so dass diese voneinander beabstandet sind. In diesen Freiraum ist zum einen das Ritzel aufgenommen, welches auf einer in beiden Platten gelagerten Antriebswelle des Handhebels sitzt, und zum anderen auch der Zahnsektor. Dieser besitzt im Abstand von der Zahnreihe ein Langloch, welches ebenfalls auf einer Kreislinie um die Drehachse des Querrohres liegt. Dieses Langloch wird von einem Niet durchragt, der der Verbindung der beiden Platten in diesem Bereich, also innerhalb des Zahnsektors, dient. Der Abstand der beiden Platten ist so gewählt, dass sich sowohl das Ritzel als auch der Zahnsektor zwischen den beiden Platten drehend bewegen kann. Im Bereich des Langlochs besitzen sowohl der Zahnsektor als auch die beiden Platten Führungen nach Art einer Nut-Feder-Verbindung, wobei die Führungen ebenfalls auf einer Kreislinie um die Drehachse des Querrohres liegen. Die dem Seitenteil des Sitzteils benachbarte Platte der Klammer ist mit dem Seitenteil verschweißt.Around In the event of a crash, prevent the pinion from disengaging from the dental sector comes is a staple for the pinion provided by which it is fixed axially on the tooth sector is. This consists of two plates attached to their the dental sector opposite ends outside of the toothed sector abut each other on two flanges and there riveted together are. After the two flange parts paragraphs are provided in the two plates, so that they are spaced apart. In this free space is on the one hand the pinion picked up, which on one in both plates stored drive shaft of the hand lever sits, and on the other hand, the Dental sector. This has a slot at a distance from the row of teeth, which also on a circular line around the axis of rotation of the cross tube lies. This slot is penetrated by a rivet, the connection of the two plates in this area, ie within the tooth sector, serves. The distance between the two plates is chosen so that both the pinion as well as the tooth sector between the two plates rotate can. In the area of the slot both the tooth sector and also the two plates guides in the manner of a tongue and groove connection, the guides also on one Circle around the axis of rotation of the cross tube lie. The side panel the seat part adjacent plate of the bracket is with the side part welded.
Diese Konstruktion ist sehr robust und verhindert im Crash-Fall ein Außereingriffkommen von Ritzel und Zahnsektor. Sie ist jedoch sehr aufwendig, da die beiden Platten der Klammer miteinander vernietet werden müssen und eine der Platten an das Seitenteil des Sitzteils angeschweißt werden muss.These Construction is very robust and prevents a disengagement in the event of a crash of pinion and dental sector. However, it is very expensive, since the both plates of the bracket must be riveted together and one of the plates to be welded to the side part of the seat part got to.
Aufgabe der vorliegenden Erfindung ist es, eine gattungsgemäße Verstellvorrichtung zur Verfügung zu stellen, die einfacher aufgebaut, leichter zu montieren und dennoch crashsicher ist.task The present invention is a generic adjustment to disposal To put, the simpler structure, easier to assemble and yet is crash-proof.
Diese Aufgabe wird erfindungsgemäß mit einer Verstellvorrichtung gelöst, die die Merkmale des Anspruchs 1 aufweist.These Task is according to the invention with a Adjustment device solved, having the features of claim 1.
Erfindungsgemäß besteht die Klammer nur noch aus einem Klammerblech. Da dieses Klammerblech mit seinem anderen Endbereich unmittelbar hinter bzw. an dem Ritzel am Sitzbauteil festgelegt ist, ergeben sich günstige Hebelverhältnisse für die Crash-Sicherheit des Eingriffs zwischen Ritzel und Zahnelement, die durch den am Rand der Öffnung anliegenden Teil dieses Endbereiches des Klammerbleches noch erhöht wird. Wenn der andere Endbereich des Klammerbleches nur hinter dem Sitzbauteil verhakt wird, was für die Crash-Sicherheit völlig ausreichend ist, vereinfacht sich die Montage, da die Verschraubung dieses Endbereiches zum Wegfall kommt. Ein weiterer Vorteil der erfindungsgemäßen Verstellvorrichtung ist darin zu sehen, dass das Klammerblech sowohl für rechte als auch linke Kraftfahrzeugsitze verwendet werden kann, also nicht zwei symmetrische Herstellungswerkzeuge erforderlich sind. Das verringert die Herstellungskosten und vereinfacht die Lagerhaltung.According to the invention the clip only from a clamp plate. As this clip sheet with its other end immediately behind or on the pinion is fixed to the seat component, resulting in favorable leverage for crash safety the engagement between pinion and toothed element, by the on Edge of the opening adjacent Part of this end portion of the clamp plate is still increased. If the other end portion of the clamp plate hooked only behind the seat component will, what for the crash safety completely is sufficient, simplifies the assembly, since the screw connection this end area comes to an end. Another advantage of Adjustment device according to the invention can be seen in the fact that the clamp plate for both right as well as left vehicle seats can be used, so not two symmetrical manufacturing tools are required. That reduces the manufacturing costs and simplifies storage.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous embodiments of the invention will become apparent from the Dependent claims.
