Description

Die vorliegende Erfindung betrifft eine Innenbetätigungsvorrichtung für Fahrzeugtüren, mit einem in einem Lagerteil über eine Schwenklagerung schwenkbeweglich gelagerten, mit einem Türschloß zum Öffnen der Tür wirkverbindbaren Betätigungshebel, wobei das Lagerteil an einer Tür-Innenverkleidung insbesondere unlösbar zu befestigen ist.The present invention relates to an internal actuating device for vehicle doors, with an actuating lever that is pivotably mounted in a bearing part via a pivot bearing and that can be operatively connected to a door lock for opening the door, the bearing part being in particular non-detachably fastened to a door interior trim.

Bei derartigen Vorrichtungen wird üblicherweise das Lagerteil mit einem flachen Umfangsrand auf einer Oberfläche einer Tür-Innenverkleidung unlösbar befestigt, und zwar entweder verklebt oder verschweißt (Reibschweißung). Hierdurch tritt der Nachteil auf, daß nachfolgend der Betätigungshebel nicht mehr ohne weiteres demontiert werden kann (was aber z.B. bei Beschädigungen zum Zwecke des Austauschs erforderlich werden kann). Dies liegt daran, daß eine für die Schwenklagerung des Betätigungshebels vorgesehene Schwenkachse als durchgehender Achsbolzen im Bereich einer Öffnung der Türverkleidung und etwa in der Ebene der Türverkleidung bzw. innerhalb eines von der Dicke der Verkleidung definierten Ebenenbereichs liegt und daher im mit der Türverkleidung verbundenen Zustand des Lagerteils nicht mehr demontiert, d.h. aus ihrer Achsaufnahme herausgezogen werden kann. Aus diesem Grund war es bisher aber auch stets erforderlich, den Betätigungshebel bereits im Lagerteil zu montieren, bevor das Lagerteil an der Türverkleidung befestigt werden konnte. Dies kann aus montagetechnischen Gründen nachteilig sein.In devices of this type, the bearing part is usually permanently attached to a surface of a door interior trim with a flat peripheral edge, either glued or welded (friction welding). As a result, there is the disadvantage that the operating lever can no longer be dismantled without further notice (which, however, may be necessary, for example, in the event of damage for the purpose of replacement). This is because a pivot axis provided for the pivot bearing of the actuating lever as a continuous axle bolt lies in the region of an opening of the door panel and approximately in the plane of the door panel or within a plane range defined by the thickness of the panel and therefore in the state of the door panel connected Not part of the stock disassembled more, ie can be pulled out of their axle holder. For this reason, it has always been necessary to mount the actuating lever in the bearing part before the bearing part could be attached to the door trim. This can be disadvantageous for assembly reasons.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, ausgehend von dem beschriebenen Stand der Technik eine gattungsgemäße Innenbetätigungsvorrichtung zu schaffen, bei der sowohl die Montage als auch eine Demontage des Betätigungshebels auch im montierten, d.h. an der Türverkleidung befestigten Zustand des Lagerteils, sehr einfach möglich sind.The present invention is based on the object, based on the described prior art, to provide a generic internal actuation device in which both the assembly and the disassembly of the actuation lever also in the assembled, i.e. attached to the door panel condition of the bearing part, are very easy.

Erfindungsgemäß wird dies dadurch erreicht, daß der Betätigungshebel mit dem Lagerteil über in axialer Richtung der Schwenklagerung federelastisch bewegliche und Bestandteile der Schwenklagerung bildende Rastmittel lösbar verbunden bzw. verbindbar ist. Durch diese vorteilhafte Ausgestaltung braucht der Betätigungshebel nur noch in dem Lagerteil "eingerastet" zu werden, so daß sich die Montage wesentlich vereinfacht. Da somit keine durchgehende, durch axiales Einschieben zu montierende Schwenkachse mehr vorhanden ist, kann auch dann eine beliebige Montage oder Demontage des Betätigungshebels erfolgen, wenn das Lagerteil mit der Türverkleidung verbunden ist. Ein Austausch des Betätigungshebels ist hierdurch jederzeit möglich, ohne daß das Lagerteil von der Verkleidung gelöst werden müßte; hierbei auftretende Beschädigungen werden somit ebenfalls sicher vermieden.According to the invention, this is achieved in that the actuating lever is detachably connected or connectable to the bearing part via spring means that are resiliently movable in the axial direction of the pivot bearing and form components of the pivot bearing. Due to this advantageous embodiment, the actuating lever only needs to be "locked" in the bearing part, so that the assembly is considerably simplified. Since there is no longer a continuous pivot axis to be mounted by axial insertion, any assembly or disassembly of the actuating lever can also take place when the bearing part is connected to the door trim. An exchange of the actuating lever is possible at any time without the bearing part having to be removed from the panel; Damage occurring in this way is thus also reliably avoided.

Weitere vorteilhafte Ausgestaltungsmerkmale der Erfindung und bevorzugte Ausführungsformen sind in den Unteransprüchen und der nachfolgenden Beschreibung enthalten.Further advantageous design features of the invention and preferred embodiments are contained in the subclaims and the description below.

In den verschiedenen Figuren der Zeichnung sind gleiche Teile stets mit den gleichen Bezugsziffern bezeichnet, so daß jede eventuell nur einmal vorkommende Beschreibung eines Teils analog auch bezüglich der anderen Zeichnungsfiguren gilt, in denen dieses Teil mit der entsprechenden Bezugsziffer ebenfalls vorkommt.In the different figures of the drawing, the same parts are always designated with the same reference numbers, so that any description of a part that may only occur once also applies analogously to the other drawing figures in which this part also appears with the corresponding reference number.

Eine erfindungsgemäße Innenbetätigungsvorrichtung besteht hauptsächlich aus drei Komponenten, einem Lagerteil 2 (Fig. 1 bis 4), einem Betätigungshebel 4 (Fig. 5) und einem Abdeckteil 6 (Fig. 6 bis 10). Der Betätigungshebel 4 ist über eine Schwenklagerung 8 in dem Lagerteil 2 schwenkbeweglich um eine Rotationsachse 10 gelagert. Dabei besteht der Betätigungshebel 4 aus einem ersten Hebelarm 12, der innerhalb einer Fahrzeugtüre z.B. über einen Seilzug mit einem Türschloß (Fallenschloß) zum Öffnen der Tür (Entriegeln des Fallenschlosses) wirkverbindbar ist, sowie einem zweiten Hebelarm, der einen von einem Fahrzeuginnenraum her zugänglichen Griffabschnitt 14 bildet (s. Fig. 5).An internal actuation device according to the invention mainly consists of three components, a bearing part 2 (FIGS. 1 to 4), an actuation lever 4 (FIG. 5) and a cover part 6 (FIGS. 6 to 10). The actuating lever 4 is pivotally mounted about a rotation axis 10 in the bearing part 2 via a pivot bearing 8. The actuating lever 4 consists of a first lever arm 12, which e.g. is operatively connected via a cable with a door lock (latch lock) for opening the door (unlocking the latch lock), and a second lever arm which forms a handle section 14 accessible from a vehicle interior (see FIG. 5).

Das Lagerteil 2 besteht aus einem im wesentlichen muldenförmigen Innenteil 16 und einem dieses umschließenden, eine Befestigungsebene definierenden Umfangsrand 18. Das Lagerteil 2 wird unlösbar an einer nicht dargestellten Tür-Innenverkleidung befestigt, indem der Umfangsrand 18 auf der einem Fahrzeuginnenraum abgekehrten und dem Türinneren zugekehrten Oberfläche der Innenverkleidung stoffschlüssig befestigt, vorzugsweise verklebt oder verschweißt (insbesondere reibverschweißt) wird. Die Schwenklagerung 8 befindet sich im Bereich einer Durchtrittsöffnung 20 für den Betätigungshebel 4, wobei diese Durchtrittsöffnung 20 ihrerseits in einem Bereich des Umfangsrandes 18 liegt.The bearing part 2 consists of an essentially trough-shaped Inner part 16 and a circumferential edge 18 surrounding it and defining a fastening plane. The bearing part 2 is permanently attached to a door lining, not shown, by the circumferential edge 18 being firmly bonded, preferably glued or welded, to the surface of the inner lining facing away from a vehicle interior and facing the interior of the door (especially friction welded). The pivot bearing 8 is located in the region of a passage opening 20 for the actuating lever 4, this passage opening 20 in turn lying in a region of the peripheral edge 18.

Erfindungsgemäß ist nun der Betätigungshebel 4 mit dem Lagerteil 2 über in axialer Richtung der Schwenklagerung 8 (Richtung der Rotationsachse 10) federelastisch bewegliche und Bestandteile der Schwenklagerung 8 bildende Rastmittel 22 lösbar verbunden bzw. verbindbar. Ein bevorzugtes Ausführungsbeispiel zur Ausgestaltung dieser Rastmittel 22 wird im folgenden anhand der Zeichnung erläutert.According to the invention, the actuating lever 4 is now detachably connected or connectable to the bearing part 2 by means of latching means 22 which are resiliently movable in the axial direction of the pivot bearing 8 (direction of the axis of rotation 10) and form components of the pivot bearing 8. A preferred embodiment for the design of this locking means 22 is explained below with reference to the drawing.

Dabei weist die Schwenklagerung 8 vorzugsweise als Schwenkachse zwei mit dem Lagerteil 2 verbundene, axial beabstandete und jeweils in eine Lageröffnung 24 des Betätigungshebels 4 eingreifende Achszapfen 26 und 28 auf. Dabei bildet einer der Achszapfen, und zwar der jeweils in den Zeichnungsfiguren "obere" Achszapfen 26, das erfindungsgemäße Rastmittel 22, indem dieser Achszapfen 26 in Richtung der Rotationsachse 10 derart federelastisch beweglich angeordnet ist, daß er aus seiner in die Lageröffnung 24 des Betätigungshebels 4 (vgl. hierzu Fig. 5) eingreifenden Lage in eine vollständig außerhalb der Lageröffnung 24 liegende Montage- bzw. Demontagestellung bewegbar ist. Hierzu ist dieser Achszapfen 26 zweckmäßigerweise an einem freien Ende eines mit dem Lagerteil 2 verbundenen, elastisch biegsamen Federarmes 30 angeordnet, der sich vorzugsweise ausgehend von dem Lagerteil 2 in Richtung des Fahrzeuginnenraumes, d.h. etwa senkrecht zur Ebene des Umfangsrandes 18 bzw. der nicht dargestellten Tür-Innenverkleidung, erstreckt. Dies ist am besten in Fig. 3 zu erkennen. Der Federarm 30 ist in Richtung des in Fig. 3 eingezeichneten Doppelpfeils 32 elastisch beweglich. Hierdurch bewegt sich dann auch der Achszapfen 26 im wesentlichen in seiner axialen Richtung. Der andere, gegenüberliegende Achszapfen 28 (in den Zeichnungen der "untere" Achszapfen) ist starr, d.h. relativ zu dem Lagerteil 2 unbeweglich mit diesem verbunden. Vorzugsweise sind die beiden Achszapfen 26, 28 einander zugekehrt angeordnet, greifen folglich in entgegengesetzte Richtungen jeweils in die Lageröffnung 24 des Betätigungshebels 4 ein. Damit liegt der Betätigungshebel 4 mit dem Bereich seiner Lageröffnung 24 praktisch "zwischen" den Achszapfen 26, 28 bzw. zwischen deren "Anbindungspunkten" des Lagerteils 2.The pivot bearing 8 preferably has, as the pivot axis, two axially spaced axle journals 26 and 28 connected to the bearing part 2 and each engaging in a bearing opening 24 of the actuating lever 4. One of the axle journals, namely the respective "upper" axle journal 26 in the drawing figures, forms the latching means 22 according to the invention, in that this axle journal 26 is arranged so as to be resiliently movable in the direction of the axis of rotation 10 such that it moves out of it into the bearing opening 24 of the actuating lever 4 (see FIG. 5) engaging position in a completely outside of the bearing opening 24 assembly or disassembly position is movable. For this purpose, this journal 26 is expediently at a free end an elastically flexible spring arm 30 connected to the bearing part 2, which preferably extends from the bearing part 2 in the direction of the vehicle interior, ie approximately perpendicular to the plane of the peripheral edge 18 or the door lining, not shown. This can best be seen in FIG. 3. The spring arm 30 is elastically movable in the direction of the double arrow 32 shown in FIG. 3. As a result, the journal 26 then moves essentially in its axial direction. The other, opposite axle journal 28 (in the drawings the "lower" axle journal) is rigid, that is to say it is immovably connected to the bearing part 2. The two axle journals 26, 28 are preferably arranged facing one another and consequently engage in the bearing opening 24 of the actuating lever 4 in opposite directions. Thus, the actuating lever 4 with the area of its bearing opening 24 is practically “between” the axle journals 26, 28 or between their “connection points” of the bearing part 2.

In einer besonders vorteilhaften Weiterbildung der Erfindung sind die Rastmittel 22 in einer den Betätigungshebel 4 haltenden Stellung arretierbar, und zwar vorzugsweise durch ein Arretierteil 34, welches lösbar mit dem Lagerteil verbindbar, insbesondere über Rastverbindungen 36 aufsteckbar ist.In a particularly advantageous development of the invention, the locking means 22 can be locked in a position holding the actuating lever 4, preferably by means of a locking part 34, which can be detachably connected to the bearing part, in particular by means of locking connections 36.

Bei dem dargestellten, bevorzugten Ausführungsbeispiel der Erfindung besitzt das Arretierteil 34 (s. hierzu insbesondere Fig. 8 und 10) eine Aufnahme 38, die im mit dem Lagerteil 2 verbundenen Zustand des Arretierteils 34 das freie Ende des Federarmes 30 aufnimmt, so daß der Federarm 30 und damit auch der bewegliche Achszapfen 26 gegen elastische Bewegungen arretiert werden, und zwar wird der Federarm 30 vorzugsweise gegen Verbiegungen in alle Richtungen, d.h. sowohl in der axialen Richtung des Achszapfens 26 (zur Sicherung der Halterung des Betätigungshebels 4), als auch in seiner Querrichtung (wodurch eine hohe Stabilität der Schwenklagerung erreicht wird) gesichert gehalten.In the preferred embodiment of the invention shown, the locking part 34 (see in particular FIGS. 8 and 10) has a receptacle 38 which, when the locking part 34 is connected to the bearing part 2, receives the free end of the spring arm 30 so that the spring arm 30 and thus also the movable axle 26 can be locked against elastic movements, namely the spring arm 30 preferably secured against bending in all directions, that is, both in the axial direction of the journal 26 (to secure the mounting of the actuating lever 4), and in its transverse direction (thereby achieving a high stability of the pivot bearing).

Bei dieser Ausgestaltung ist es zudem besonders zweckmäßig, das Arretierteil 34 als Bestandteil des Abdeckteils 6 zu bilden. Wie sich aus den Fig. 6 bis 10 ergibt, besitzt das Abdeckteil 6 eine Durchtrittsöffnung 40 für den Betätigungshebel 4, wobei in einem dieser Öffnung 40 benachbarten Bereich das Arretierteil 34 gebildet ist, welches den Bereich des beweglichen Federarms 30 abdeckt und auf seiner dem Lagerteil 2 zugekehrten Innenseite die Aufnahme 38 für den Federarm 30 aufweist (siehe insbesondere Fig. 6, 8 und 10). Das Abdeckteil 6 weist zudem im Bereich des Griffabschnittes 14 des Betätigungshebels 4 eine muldenartige Vertiefung 42 auf, die ein Hintergreifen des Griffabschnittes 14 ermöglicht. Die oben bereits erwähnten Rastverbindungen 36 zur lösbaren Befestigung des Arretierteils an dem Lagerteil 2 bestehen vorzugsweise aus Rastfederarmen 44 des Abdeckteils 6 und aus entsprechenden Rastöffnungen 46 des Lagerteils 2. Es handelt sich hierbei somit um "schnappbare Formschlußverbindungen", die ein einfaches Aufstecken bzw. Aufklipsen des Abdeckteils 6 auf das Lagerteil 2 ermöglichen.In this embodiment, it is also particularly expedient to form the locking part 34 as part of the cover part 6. As can be seen from FIGS. 6 to 10, the cover part 6 has a passage opening 40 for the actuating lever 4, the locking part 34, which covers the region of the movable spring arm 30 and on the bearing part, being formed in a region adjacent to this opening 40 2 facing inside the receptacle 38 for the spring arm 30 (see in particular FIGS. 6, 8 and 10). The cover part 6 also has a trough-like recess 42 in the region of the grip section 14 of the actuating lever 4, which allows the grip section 14 to reach behind. The above-mentioned locking connections 36 for releasably fastening the locking part to the bearing part 2 preferably consist of locking spring arms 44 of the cover part 6 and of corresponding locking openings 46 of the bearing part 2. These are thus “snap-fit connections” which are simple to plug on or clip on of the cover part 6 on the bearing part 2.

Es ist weiterhin besonders vorteilhaft, wenn mindestens einer der Achszapfen 26, 28, im dargestellten Ausführungsbeispiel der untere, feststehende Achszapfen 28, eine sich in Richtung seines freien Endes konisch verjüngende Form aufweist, wobei dann vorzugsweise auch die zugehörige Lageröffnung 24 des Betätigungshebels 4 entsprechend konisch ausgebildet ist. Diese vorteilhafte Maßnahme gewährleistet einen selbsttätigen Ausgleich von axialem Lagerspiel, und zwar insbesondere im Zusammenwirken mit der Federelastizität des Federarmes 30, wodurch der Betätigungshebel 4 stets in Richtung des gegenüberliegenden Achszapfens in Vorspannung gehalten wird.It is also particularly advantageous if at least one of the axle journals 26, 28, in the exemplary embodiment shown the lower, stationary axle journal 28, has a shape which tapers conically in the direction of its free end, with the associated bearing opening 24 of the actuating lever 4 also preferably correspondingly is conical. This advantageous measure ensures an automatic compensation of axial bearing play, in particular in cooperation with the spring elasticity of the spring arm 30, whereby the actuating lever 4 is always held in the direction of the opposite journal in pretension.

In Fig. 5 ist noch eine weitere vorteilhafte Ausgestaltung der Erfindung veranschaulicht. Demnach weist der Betätigungshebel 4 in einem der für den beweglichen Achszapfen 26 vorgesehenen Lageröffnung 24 in Montagerichtung vorgeordneten Bereich eine Auflaufschrägfläche 48 auf. Zusätzlich oder aber alternativ hierzu kann auch der bewegliche Achszapfen 26 eine Auflaufschrägfläche (nicht dargestellt) für den Betätigungshebel aufweisen. Mit dieser Ausgestaltung wird erreicht, daß bei der Montage des Betätigungshebels 4 eine selbsttätige Bewegung des federelastischen Achszapfens 26 über die Auflaufschrägfläche 48 bewirkt wird. Der Betätigungshebel 4 wird hierzu zunächst mit seiner "unteren" Lageröffnung 24 auf den feststehenden Achszapfen 28 aufgesetzt und dann in Richtung des Lagerteils 2 gekippt, bis der bewegliche Achszapfen 26 über die Auflaufschrägfläche 48 in seine Montagestellung bewegt wird. Nachfolgend schnappt der Achszapfen 26 dann in die Lageröffnung 24 ein. Damit ist bereits der Montagevorgang des Betätigungshebels 4 beendet. Es braucht dann nur noch das Abdeckteil 6 aufgesteckt zu werden.A further advantageous embodiment of the invention is illustrated in FIG. 5. Accordingly, the actuating lever 4 has a run-up inclined surface 48 in one of the bearing openings 24 provided in the mounting direction for the movable axle journal 26. In addition or as an alternative to this, the movable axle journal 26 can also have a run-up inclined surface (not shown) for the actuating lever. With this configuration it is achieved that during the assembly of the actuating lever 4 an automatic movement of the resilient axle journal 26 is effected via the ramp surface 48. For this purpose, the actuating lever 4 is first placed with its "lower" bearing opening 24 on the fixed axle journal 28 and then tilted in the direction of the bearing part 2 until the movable axle journal 26 is moved into its assembly position via the ramp inclined surface 48. Subsequently, the journal 26 snaps into the bearing opening 24. The assembly process of the actuating lever 4 has thus already ended. It then only needs to be plugged on the cover 6.

Auch eine Demontage des Betätigungshebels 4 ist sehr einfach möglich, indem zunächst das Abdeckteil 6 durch Lösen der Rastverbindungen 36 abgenommen wird. Es kann dann der Federarm 30 mit einem geeigneten Werkzeug, z.B. einem Schraubendreher, elastisch verbogen werden, bis der Achszapfen 26 ganz aus der Lageröffnung 24 herausbewegt ist (Demontagestellung). Hierzu ist es vorteilhaft, wenn der Federarm 30 an seinem freien Ende einen Betätigungsabschnitt 50 (s. Fig. 3) zum Ansetzen des Werkzeuges aufweist. Bei dem Betätigungsabschnitt 50 kann es sich um eine Vertiefung oder - wie dargestellt - um einen Stegansatz handeln, der mit einer Schraubendreher-Klinge untergriffen werden kann, um den Federarm in eine Lösestellung zu verbiegen.Dismantling of the actuating lever 4 is also very easily possible by first removing the cover part 6 by releasing the latching connections 36. The spring arm 30 can then be bent elastically using a suitable tool, for example a screwdriver, until the axle journal 26 is completely moved out of the bearing opening 24 (disassembly position). For this purpose, it is advantageous if the spring arm 30 has an actuating section 50 (see FIG. 3) at its free end for attaching the tool. The actuating section 50 can be a depression or - as shown - a web extension which can be gripped under with a screwdriver blade in order to bend the spring arm into a release position.

Ergänzend ist noch zu erwähnen, daß der Betätigungshebel 4 zweckmäßigerweise aus Metall, insbesondere aus verchromtem (hochglanzverchromtem) Stahl besteht, während das Lagerteil 2 und das Abdeckteil 6 bevorzugt aus Kunststoff, und zwar aus einem faserverstärkten Kunststoff auf der Basis von Polyamid 66 bzw. Polyamid 6 bestehen, d.h. als jeweils einstückige Kunststoff-Spritzgußteile ausgebildet sind.In addition, it should also be mentioned that the actuating lever 4 expediently consists of metal, in particular of chromed (high-gloss chromium-plated) steel, while the bearing part 2 and the cover part 6 preferably consist of plastic, specifically from a fiber-reinforced plastic based on polyamide 66 or polyamide 6 exist, ie are each formed as one-piece plastic injection molded parts.

Die Erfindung ist nicht auf das dargestellte und beschriebene Ausführungsbeispiel beschränkt, sondern umfaßt auch alle im Sinne der Erfindung gleichwirkenden Ausführungen. Beispielsweise könnte die Schwenklagerung 8 auch aus mit dem Betätigungshebel 4 verbundenen Achszapfen bestehen, die dann in entsprechende Lageröffnungen des Lagerteils 2 eingreifen würden. Dabei wäre ebenfalls mindestens eines der Lagerteile (einer der Achszapfen oder eine der Lageröffnungen) axial federelastisch beweglich. Alle hierfür möglichen Ausführungsvarianten liegen demzufolge im Bereich der Erfindung.The invention is not limited to the exemplary embodiment shown and described, but also encompasses all embodiments having the same effect in the sense of the invention. For example, the pivot bearing 8 could also consist of axle journals connected to the actuating lever 4, which would then engage in corresponding bearing openings in the bearing part 2. At least one of the bearing parts (one of the axle journals or one of the bearing openings) would also be axially resiliently movable. All possible design variants for this are therefore within the scope of the invention.
