Abstract

The vehicle heating or air conditioning system has two separate air duct flaps (2), controlled by a single shaft (7), whose ends (8) have a non-round profile, that cooperates with contact surfaces (12) of a radially open recess (6). The recess is formed on each flap axle (5), to prevent their relative rotation. At least one clip (10) on each recess expands, when the shaft is pressed into the recess, and then springs back to lock the shaft in place. ADVANTAGE - Simple precise, sync flap operation and assembly, permitting automation.

Description

Die Erfindung betrifft eine Verstelleinrichtung für zwei im Abstand voneinander in jeweils einem Luftkanal einer Heizungs- oder Klimatisierungsanlage eines Kraftwagens angeordnete Klap­ pen, die über eine Betätigungswelle miteinander verbunden sind, wobei jede Klappe auf ihrer der Betätigungswelle zugekehrten Seite einen Lagerzapfen mit einer radial offenen Ausnehmung aufweist, in die die Betätigungswelle absenkbar und durch eine Klipsverbindung lagesicherbar ist.The invention relates to an adjustment device for two in Distance from each other in an air duct of a heating or Klap arranged air conditioning system of a motor vehicle pen, which are connected to each other via an actuating shaft, each flap facing the actuating shaft Side a journal with a radially open recess has, in which the actuating shaft can be lowered and by a Clip connection can be secured in position.

Eine derartige Verstelleinrichtung ist durch das DE-GM 86 27 710 bekannt, wobei durch Verdrehen der Betätigungswelle relativ zu einem Lagerzapfen in der Schließstellung beider Klappen im Bereich eines Kupplungsstückes zunächst der Synchronlauf beider Klappen herbeigeführt wird und die so erreichte Kupplungsposi­ tion durch Aufklipsen eines Deckelteiles gesichert wird. Bei diesem Aufklipsvorgang, der aufgrund des Herumschwenkens des an dem Lagerzapfen angeformten Deckels nur schwierig automa­ tisierbar ist, muß zur Beibehaltung der Einstellposition jede Luftklappe in ihrer Schließstellung gehalten werden, was den Montagevorgang zusätzlich erschwert.Such an adjustment device is by DE-GM 86 27 710 known, by rotating the actuating shaft relatively to a bearing journal in the closed position of both flaps in Area of a coupling piece, the synchronous operation of both Flaps is brought about and the coupling posi thus achieved tion is secured by clipping on a cover part. At this clipping process, which is due to the swinging of the on the molded cover lid difficult automa is tisizable, each must to maintain the setting position Air flap are kept in their closed position, which the Assembly process made even more difficult.

Der Erfindung liegt die Aufgabe zugrunde, unter Erhalt eines ausreichend genauen Synchronlaufs beider Klappen den Montagevorgang so zu vereinfachen, daß auch eine automatisierte Durchführung dieses Montageschrittes möglich ist. The invention has for its object to obtain a sufficient so the exact synchronous running of both flaps the assembly process simplify that even an automated implementation of this Assembly step is possible.  

Diese Aufgabe wird bei einer Verstelleinrichtung nach dem Oberbegriff des Patentanspruches 1 durch dessen kennzeichnende Merkmale gelöst. Unter unrundem Profil sind in diesem Zusam­ menhang alle Profilarten zu verstehen, die im Zusammenwirken mit entsprechenden Anlageflächen der Ausnehmung einen Verdreh­ schutz für die Betätigungswelle erwirken. So ist auch eine Be­ tätigungswelle mit rundem Profil einsetzbar, das ausnehmungs­ seitig durch mindestens einem Vorsprung oder eine Vertiefung unterbrochen ist, wobei jeder Profilunterbrechung eine gegen­ gerichtete Aus- bzw. Anformung der Ausnehmung zugeordnet ist.This task is performed with an adjustment device according to the Preamble of claim 1 by the characterizing Features solved. Under non-circular profile are in this together menhang to understand all types of profiles that work together a rotation with corresponding contact surfaces of the recess obtain protection for the actuation shaft. So is a Be actuation shaft with round profile can be used, the recess on one side by at least one protrusion or recess is interrupted, with each profile interruption one against directed molding or molding of the recess is assigned.

Das Absenken der Betätigungswelle in die Ausnehmungen gestaltet sich einfach, wenn an jeder Ausnehmung zwei einander gegen­ überliegende Klipse vorgesehen sind, die die Öffnung der Aus­ nehmung überragen und wenn jeder Klips mit einer zur Ausneh­ mung abfallenden Anlaufschräge für die abzusenkende Betäti­ gungswelle versehen ist.The lowering of the actuating shaft is designed in the recesses easy when two against each other at each recess Overlying clips are provided that open the opening Take over and if each clip with one to the exception starting slope for the actuator to be lowered shaft is provided.

Der Gegenstand der Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläu­ tert. Es zeigt:The subject matter of the invention is described in the following in the illustrated embodiment illustrated in more detail tert. It shows:

Fig. 1 den Kupplungsbereich der beiden klappenseitigen Lagerzapfen mit der Betätigungswelle und Fig. 1 shows the coupling area of the two flap-side bearing pins with the actuating shaft and

Fig. 2 den Schnitt nach der Linie II-II in Fig. 1. Fig. 2 shows the section along the line II-II in FIG. 1.

Eine nicht näher dargestellte Heizungs- oder Klimatisierungs­ einrichtung eines Kraftwagens ist mit zwei angedeuteten, z. B. den linken und rechten Fußraum mit Luft versorgenden Luftkanä­ len 1 ausgerüstet, die mit seitlichem Abstand voneinander an­ geordnet sind. Jeder Luftkanal 1 nimmt eine Klappe 2 schwenkbar auf, die randseitig von einer Dichtung 3 umgeben ist. Um beide Klappen 2 miteinander verbinden zu können, so daß beim Schwen­ ken einer Klappe 2 die andere Klappe 2 mitgenommen wird, sind die beiden einander zugekehrten Lagerstellen 4 der Klappen 2 jeweils mit einem Lagerzapfen 5 versehen, dessen aus dem Luft­ kanal 1 austretender Bereich eine radial offene Ausnehmung 6 aufweist. In beide Ausnehmungen 6 ist eine Betätigungswelle 7 abgesenkt, die mit einem unrunden, gemäß Fig. 2 quadratischen Profil 8 versehen ist und durch eine Klipsanordnung 9 gegen ein ungewolltes Verlassen der Ausnehmungen 6 gesichert ist.A heating or air conditioning device, not shown, of a motor vehicle is indicated with two, for. B. the left and right footwell with air supplying Luftkanä len 1 , which are arranged at a lateral distance from each other. Each air duct 1 pivots on a flap 2 , which is surrounded on the edge side by a seal 3 . To both flaps 2 combine with each other so that when Schwen ken of a flap 2 the other flap 2 taken along, are the two mutually facing bearing points 4 of the flaps 2 are each provided with a bearing pin 5 whose emerging from the air duct 1 region, a has radially open recess 6 . In both recesses 6 , an actuating shaft 7 is lowered, which is provided with a non-circular profile 8 , as shown in FIG. 2, and is secured by a clip arrangement 9 against unintentional leaving of the recesses 6 .

Die Klipsanordnung 9 besteht aus zwei an der Ausnehmung 6 an­ geformten, einander gegenüberliegenden Klipsen 10, die die Öffnung der Ausnehmung 6 überragen und die mit jeweils einer zur Ausnehmung 6 hin abfallenden Anlaufschräge 11 versehen sind, so daß beim Ansetzen der Betätigungswelle 7 zum Zwecke ihres Absenkens in die Ausnehmungen 6, die Betätigungswelle 7 unter Seitwärtsbiegen der beiden Klipse 10 an den Anlauf­ schrägen 11 abgeleitet und in die Ausnehmungen 6 abgesenkt wird, die mit auf des Profil 8 der Betätigungswelle 7 abge­ stimmten, diese verdrehsicher aufnehmenden Anlageflächen 12 ausgestaltet sind. Ist die Absenkposition erreicht, so nehmen die beiden Klipse 10 ihre Ausgangslage wieder ein und über­ greifen dabei die Betätigungswelle 7, die dadurch beim Verschwenken der Klappen 2 an einem Herausfallen gehindert wird.The clip assembly 9 consists of two on the recess 6 on shaped, opposing clips 10 , which protrude beyond the opening of the recess 6 and which are each provided with a sloping slope 11 towards the recess 6 , so that when the actuating shaft 7 is attached for the purpose of it Lowering into the recesses 6 , the actuating shaft 7 derived by sideways bending of the two clips 10 to the run-up slope 11 and lowered into the recesses 6 , which agreed with on the profile 8 of the actuating shaft 7 , these non-rotatably receiving contact surfaces 12 are designed. Once the lowering position has been reached, the two clips 10 return to their starting position and thereby engage the actuating shaft 7 , which is thereby prevented from falling out when the flaps 2 are pivoted.
