Description
Die Erfindung betrifft eine Kraftfahrzeugtürgriff mit einem Handgriff, der in einem Griffgehäuse angeordnet und durch Drehung um eine Drehachse von einer Ruheposition in eine Betätigungsposition verlagerbar ist, wobei ein an der Rückseite des Handgriffs am freien Ende angeordneter Griffhaken kinematisch mit einem Umlenkhebel gekoppelt ist, wobei der Umlenkhebel bei der Verlagerung von der Ruheposition in die Betätigungsposition mittelbar oder unmittelbar auf ein Kraftfahrzeugtürschloss einwirkt, um eine Freigabe des Schlosses zu bewirken und eine Öffnung der Kraftfahrzeugtür zu ermöglichen.The invention relates to a motor vehicle door handle with a handle which is arranged in a handle housing and displaceable by rotation about an axis of rotation from a rest position to an actuating position, wherein a arranged at the back of the handle at the free end handle hook is kinematically coupled to a lever, wherein the Relay lever during the displacement of the rest position in the operating position acts directly or indirectly on a motor vehicle door lock to effect a release of the lock and to allow an opening of the vehicle door.
Derartige Kraftfahrzeugtürgriffanordnungen zur Betätigung einer Kraftfahrzeugtür sind bekannt. Nachteilig bei den bekannten Anordnungen ist es, dass diese aufgrund des Lagerspiels an der Drehachse, um die der Handgriff von seiner Ruheposition in eine Betätigungsposition verlagerbar ist, einen negativen haptischen Eindruck auf den Benutzer machen, wenn der an der Rückseite des Handgriffs am freien Ende angeordnete Griffhaken in dem Bereich, in welchem er das Griffgehäuse durchgreift, hin und her wackelt. Sofern dieser Bereich, in welchem der am freien Ende des Handgriffs angeordnete Griffhaken in dem Griffgehäuse eine zu enge Führung bildet, können wiederum unerwünschte Geräusche bei der Betätigung des Kraftfahrzeugtürgriffs entstehen.Such motor vehicle door handle assemblies for actuating a motor vehicle door are known. A disadvantage of the known arrangements is that these make a negative haptic impression on the user due to the bearing clearance on the axis of rotation, by which the handle is displaced from its rest position to an operating position, when arranged at the back of the handle at the free end Handle hook in the area in which he passes through the handle housing, wiggling back and forth. If this area, in which the arranged at the free end of the handle grip hook in the handle housing forms too narrow guide, in turn, unwanted noise may arise when operating the motor vehicle door handle.
Die Aufgabe der Erfindung ist es daher, eine Kraftfahrzeugtürgriffanordnung zur Betätigung einer Kraftfahrzeugtür derart weiterzubilden, dass diese eine verbesserte Führung insbesondere des Griffhakens aufweist.The object of the invention is therefore to develop a motor vehicle door handle assembly for actuating a motor vehicle door such that it has an improved guide in particular of the handle hook.
Diese Aufgabe wird erfindungsgemäß durch eine Kraftfahrzeugtürgriffanordnung gemäß Anspruch 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by a motor vehicle door handle assembly according to claim 1. Advantageous developments of the invention are specified in the subclaims.
Besonders vorteilhaft bei dem Kraftfahrzeugtürgriff mit einem Handgriff, der in einem Griffgehäuse angeordnet und durch Drehung um eine Drehachse von einer Ruheposition in eine Betätigungsposition verlagerbar ist, wobei ein an der Rückseite des Handgriffs am freien Ende angeordneter Griffhaken kinematisch mit einem Umlenkhebel gekoppelt ist, wobei der Umlenkhebel bei der Verlagerung von der Ruheposition in die Betätigungsposition mittelbar oder unmittelbar auf ein Kraftfahrzeugtürschloss einwirkt, um eine Freigabe des Schlosses zu bewirken und eine Öffnung der Kraftfahrzeugtür zu ermöglichen, ist es, dass der Griffhaken zumindest ein Führungselement aufweist, mittels dessen der Griffhaken in einem korrespondierenden Profil des Griffgehäuses geführt ist, wobei das Führungselement mit dem Griffhaken einen Formschluss bildet.Particularly advantageous in the motor vehicle door handle with a handle which is arranged in a handle housing and displaceable by rotation about an axis of rotation from a rest position to an actuating position, wherein a arranged on the back of the handle at the free end handle hook is kinematically coupled to a lever, wherein the Relay lever during the displacement of the rest position in the operating position indirectly or directly acts on a motor vehicle door lock to effect a release of the lock and to allow an opening of the vehicle door, it is that the handle hook has at least one guide element, by means of which the handle hook in a corresponding profile of the handle housing is guided, wherein the guide element forms a positive connection with the handle hook.
Zur Öffnung der Kraftfahrzeugtür wird dementsprechend bei entriegeltem Kraftfahrzeugtürschloss der Handgriff seitens des Benutzers ergriffen und von einer Ruheposition in eine Öffnungsposition verlagert. Der Handgriff weist auf seiner Rückseite einen Griffhaken auf, der kinematisch mittelbar oder unmittelbar mit dem Umlenkhebel gekoppelt ist. Bei einer Verlagerung des Handgriffs von der Ruheposition in die Öffnungsposition wird aufgrund der kinematischen Kopplung des Handgriffs mit dem Umlenkhebel eine Drehung des Umlenkhebels um dessen Drehachse herum von der Ruheposition in die Betätigungsposition des Umlenkhebels bewirkt, so dass bei entriegeltem Kraftfahrzeugtürschloss ein Öffnen der Kraftfahrzeugtür möglich ist.Accordingly, when the motor vehicle door lock is unlocked, the handle is gripped by the user and is moved from a rest position into an open position for opening the motor vehicle door. The handle has on its back on a handle hook, which is kinematically coupled directly or indirectly with the lever. In a displacement of the handle from the rest position to the open position due to the kinematic coupling of the handle with the lever rotation of the reversing lever is effected about its axis of rotation from the rest position to the operating position of the reversing lever, so that when unlocked motor vehicle door lock opening the vehicle door is possible ,
Dadurch, dass der Griffhaken zumindest ein Führungselement aufweist, mittels dessen der Griffhaken in einen korrespondierenden Profil des Griffgehäuses geführt ist, weist der Handgriff insgesamt ein deutlich verringertes Kippspiel insbesondere von kleiner als +/- 1°, besonders bevorzugt von kleiner als +/- 0,5° auf. Durch dieses minimale Kippspiel ist der haptische Eindruck des Kraftfahrzeugtürgriffs für den Benutzer deutlich verbessert, da mittels des Führungselementes der Griffhaken geführt ist und das Lagerspiel im Bereich der Drehachse, um die der Handgriff herum von der Ruheposition in Betätigungsposition verdrehbar ist, durch das Führungselement ausgeglichen wird.Characterized in that the handle hook has at least one guide element, by means of which the handle hook in a corresponding profile of the handle housing is guided, the handle has a total significantly reduced tilting play, in particular of less than +/- 1 °, more preferably of less than +/- 0.5 °. Due to this minimal tilting play, the haptic impression of the motor vehicle door handle is significantly improved for the user because the handle hook is guided by means of the guide element and the bearing clearance in the area of the rotation axis about which the handle is rotatable from the rest position to the actuation position is compensated by the guide element ,
Ferner ist es durch dieses als zusätzliches Bauteil vorgesehene Führungselement möglich, verschiedene Werkstoffe miteinander zu kombinieren, die bessere Gleiteigenschaften aufweisen. Insbesondere kann das Führungselement aus einem Material gebildet sein, welches optimierte Gleiteigenschaften aufweist, so dass insbesondere auch unerwünschte Geräusche wie beispielsweise ein Quietschen bei der Betätigung des Kraftfahrzeugtürgriffs, wirksam unterbunden werden.Furthermore, it is possible by this provided as an additional component guide element to combine different materials together, which have better sliding properties. In particular, the guide element may be formed of a material which has optimized sliding properties, so that in particular unwanted noise such as squeaking during actuation of the motor vehicle door handle, effectively prevented.
Dadurch, dass das Führungselement mit dem Griffhaken einen Formschluss bildet, ist eine optimale Befestigung und Montage des Führungselementes an dem Griffhaken auf besonders vorteilhafte und einfache Weise möglich.Characterized in that the guide element forms a positive connection with the handle hook, an optimal fastening and mounting of the guide element on the handle hook in a particularly advantageous and simple manner possible.
Vorzugsweise weist der Griffhaken an seinem freien Ende seitlich abstehende Kopplungszapfen auf, die in entsprechenden Ausnehmungen an dem Umlenkhebel einliegen. Solche Kopplungszapfen, die seitlich an dem freien Ende des Griffhakens abstehen bilden somit das Lager für den Umlenkhebel. Mit dem freien Ende des Griffhakens ist das dem Umlenkhebel zugewandte Ende des Griffhakens bezeichnet. Über das freie Ende ist der Griffhaken mit dem Umlenkhebel kinematisch gekoppelt.Preferably, the handle hook at its free end laterally projecting coupling pin, which einliegen in corresponding recesses on the lever. Such coupling pins which protrude laterally at the free end of the handle hook thus form the bearing for the lever. With the free end of the handle hook the lever facing the end of the handle hook is called. About the free end of the handle hook is kinematically coupled to the lever.
Besonders bevorzugt umgreift das Führungselement die Kopplungszapfen zumindest teilweise formschlüssig. Indem das Führungselement nicht nur den Griffhaken formschlüssig umgreift, sondern ferner die Kopplungszapfen zumindest teilweise formschlüssig umgreift, wird die Kopplung mit dem Umlenkhebel optimiert, da das Führungselement hierdurch gleichzeitig den Lagerbereich zur Kopplung mit dem Umlenkhebel bildet. Im Bereich der Kopplung der Lagerzapfen mit dem Umlenkhebel dient das Führungsprofil dann vorzugsweise gleichzeitig als Gleitelement mit optimierten Gleiteigenschaften.Particularly preferably, the guide element surrounds the coupling pin at least partially positively. By the guide element not only engages around the handle hook form-fitting, but also at least partially positively engages the coupling pin, the coupling is optimized with the lever, since the guide element thereby simultaneously the Storage area forms for coupling with the lever. In the area of the coupling of the bearing journals with the deflection lever, the guiding profile then preferably simultaneously serves as a sliding element with optimized sliding properties.
Besonders bevorzugt ist das Führungselement als U-Profil ausgebildet, welches von einer Seite über den Griffhaken aufgesteckt ist. Dabei kann der Griffhaken insbesondere einen rechteckigen Querschnitt aufweisen, wobei die Querschnittsfläche des Griffhakens über der Länge des Griffhakens konstant oder veränderlich sein kann. Der senkrechte Schnitt durch den Griffhaken kann somit ebenfalls einem Rechteck entsprechen. Insgesamt kann der Griffhaken eine gebogene Kontur aufweisen, insbesondere vollstandig oder abschnittweise einen Kreisbogenabschnitt entsprechen, so dass der Griffhaken zumindest abschnittweise auf einem Kreisbogen um die Drehachse des Handgriffs herum liegt.Particularly preferably, the guide element is designed as a U-profile, which is attached from one side over the handle hook. In this case, the handle hook in particular have a rectangular cross-section, wherein the cross-sectional area of the handle hook over the length of the handle hook can be constant or variable. The vertical section through the handle hook can thus also correspond to a rectangle. Overall, the handle hook may have a curved contour, in particular completely or partially correspond to a circular arc section, so that the handle hook is at least partially on a circular arc around the axis of rotation of the handle around.
Das Führungselement bildet somit bevorzugt einen Gleitschuh für den Griffhaken. Dieser Gleitschuh umgreift den Griffhaken zumindest teilweise, bevorzugt in Form eines den Griffhaken übergreifenden U-Profils.The guide element thus preferably forms a sliding shoe for the handle hook. This sliding block engages around the handle hook at least partially, preferably in the form of a handle hook overarching U-profile.
Vorzugsweise weist das Führungselement Rastnasen auf, die in Hinterschneidungen und/oder Ausnehmungen in dem Griffhaken eingreifen. Alternativ oder kumulativ kann der Griffhaken an seiner Außenkontur Rastnasen aufweisen, die in entsprechende Hinterschneidungen und/oder Ausnehmungen und/oder Durchbrüche in dem Führungselement eingreifen. Durch derartige Rastnasen an dem Führungselement und/oder an dem Griffhaken, die in Hinterschneidungen und/oder Ausnehmungen in dem Griffhaken bzw. dem Führungselement eingreifen, ist es möglich, das Führungselement, welches mit dem Griffhaken einen Formschluss bildet, in einfacher Weise auf den Griffhaken aufzustecken und durch Clipsen der Rastnasen in die entsprechenden Hinterschneidungen und/oder Ausnehmungen an dem Gegenstück zu befestigen.Preferably, the guide element has latching lugs which engage in undercuts and / or recesses in the handle hook. Alternatively or cumulatively, the handle hook may have locking lugs on its outer contour, which engage in corresponding undercuts and / or recesses and / or openings in the guide element. By such locking lugs on the guide element and / or on the handle hook, which engage in undercuts and / or recesses in the handle hook or the guide element, it is possible, the guide element which forms a positive connection with the handle hook, in a simple manner on the handle hook aufzustecken and attach by clipping the locking lugs in the corresponding undercuts and / or recesses on the counterpart.
Besonders bevorzugt weist das Führungselement außenseitig längsverlaufende positive Führungsprofile auf, die mit negativen Führungsprofilen in dem denParticularly preferably, the guide element on the outside longitudinally extending positive guide profiles, which with negative guide profiles in the
Griffhaken führenden Profil des Griffgehäuses zusammenwirken. Dementsprechend können auf der Außenseite des Führungsprofils Rippen angeordnet sein, die in korrespondierenden Ausnehmungen in dem den Griffhaken führenden Profil des Griffgehäuses entlang gleiten. Mit dem Begriff längsverlaufend ist dabei die Längsrichtung, d.h. die Bewegungsrichtung des Griffhakens bei einem Verdrehen des Handgriffes um seine Drehachse zur Betätigung des Kraftfahrzeugtürgriffs bezeichnet.Handle hook cooperate leading profile of the handle housing. Accordingly, ribs can be arranged on the outer side of the guide profile, which slide in corresponding recesses in the handle hook leading profile of the handle housing along. With the term longitudinal, while the longitudinal direction, i. denotes the direction of movement of the handle hook upon rotation of the handle about its axis of rotation for actuating the motor vehicle door handle.
Alternativ oder kumulativ kann das Führungselement außenseitig längsverlaufende negative Führungsprofile aufweisen, die mit positiven Führungsprofilen in dem den Griffhaken führenden Profil des Griffgehäuses zusammenwirken. In diesem Fall weist das den Griffhaken führenden Profil des Griffgehäuses Vorsprünge auf, die in außenseitig an dem Führungselement verlaufenden Rillen eingreifen.Alternatively or cumulatively, the guide element may have longitudinally extending negative guide profiles on the outside, which interact with positive guide profiles in the grip hook leading profile of the handle housing. In this case, the grip hook leading profile of the handle housing on projections which engage in grooves extending on the outside of the guide element.
Solche längsverlaufenden Führungsprofile bilden dementsprechend äußere Rippen und/oder Ausnehmungen, die mit entsprechenden Ausnehmungen und/oder Rippen an dem den Griffhaken führenden Profil des Griffgehäuses zusammenwirken. Hierdurch wird eine optimierte und das Lagerspiel ausgleichende Führung des Griffhakens gebildet, so dass der Handgriff des Kraftfahrzeugtürgriffs insgesamt ein minimales Kippspiel aufweist und optimal in dem Griffgehäuse geführt ist.Such longitudinal guide profiles accordingly form outer ribs and / or recesses which cooperate with corresponding recesses and / or ribs on the handle hook leading profile of the handle housing. As a result, an optimized and the bearing clearance compensating leadership of the handle hook is formed so that the handle of the motor vehicle door handle has a total of minimal tilting play and is optimally guided in the handle housing.
Insbesondere kann in die Durchbrechung in dem Griffgehäuse, die durch den Griffhaken an dem Handgriff durchgriffen wird, ein Profileinsatz eingesetzt sein, insbesondere aus einem Material mit optimierten Gleiteigenschaften. Dieser Profileinsatz ist entsprechend konturiert und wirkt mit dem insbesondere außenseitig profilierten Führungselement an dem Griffhaken zusammen.In particular, can be used in the opening in the handle housing, which is penetrated by the handle hook on the handle, a profile insert, in particular of a material with optimized sliding properties. This profile insert is contoured accordingly and cooperates with the particular outside profiled guide member on the handle hook.
Vorzugsweise sind der Handgriff und der Griffhaken einstückig ausgebildet. Alternativ kann der Griffhaken als gesondertes Bauteil beispielsweise durch eine Verschraubung und/oder einen Formschluss und/oder einen Kraftschluss an dem Handgriff befestigt sein. Insbesondere können der Handgriff und der Griffhaken aus faserverstärktem Polyamid gebildet sein.Preferably, the handle and the handle hook are integrally formed. Alternatively, the handle hook can be attached as a separate component, for example, by a screw and / or a positive connection and / or a frictional connection to the handle. In particular, the handle and the handle hook can be formed from fiber-reinforced polyamide.
Besonders bevorzugt ist das Führungselement aus Kunststoff gebildet, insbesondere aus Polyoxymethylen. Dieses Material weist gegenüber dem Material des Griffhakens optimierte Gleiteigenschaften auf, so dass der das Führungselement aufweisende Griffhaken in dem den Griffhaken aufnehmenden Profil innerhalb des Griffgehäuses optimal entlang gleiten kann.Particularly preferably, the guide element is formed from plastic, in particular polyoxymethylene. This material has compared to the material of the handle hook optimized sliding properties, so that the guide member having handle hook in the handle hook receiving profile within the handle housing can slide along optimally.
Vorzugsweise sind der Umlenkhebel und/oder der Handgriff des Kraftfahrzeugtürgriffs in Richtung auf die Ruheposition federbelastet. Hierdurch ist gewährleistet, dass der Handgriff nach dem Loslassen durch den Benutzer automatisch in die Ruheposition durch eine Drehung um seine Drehachse zurückschwenkt.Preferably, the reversing lever and / or the handle of the motor vehicle door handle are spring-loaded in the direction of the rest position. This ensures that the handle after releasing by the user automatically pivots back into the rest position by a rotation about its axis of rotation.
Durch eine derartige Federbelastung von Umlenkhebel und/oder Handgriff ist gewährleistet, dass der Umlenkhebel und der Handgriff nach dem Loslassen durch einen Benutzer in die Ruheposition zurückverlagert werden, da der Umlenkhebel und der Handgriff mittelbar oder unmittelbar kinematisch gekoppelt sind.By such a spring load of the lever and / or handle ensures that the lever and the handle are relocated after releasing by a user in the rest position, since the lever and the handle are indirectly or directly kinematically coupled.
Vorzugsweise ist der Umlenkhebel über ein Schubgestänge und/oder ein Zuggestänge und/oder einen Seilzug mit dem Kraftfahrzeugtürschloss gekoppelt, wodurch bei einem nicht verriegelten Kraftfahrzeugtürschloss bei der Drehung des Umlenkhebels in seine Betätigungsposition das Öffnen des Kraftfahrzeugtürschlosses bewirkt wird.Preferably, the reversing lever is coupled via a push rod and / or a pull rod and / or a cable to the motor vehicle door lock, whereby the opening of the motor vehicle door lock is effected in an unlocked motor vehicle door lock during rotation of the reversing lever in its operating position.
In einer bevorzugten Ausführungsform weist der Umlenkhebel zumindest ein Rastelement auf, welches bei Auftreten eines äußeren Impulses in Folge eines Seitenaufpralls mit einer Unfallsperre in Eingriff kommt und eine Verlagerung des Umlenkhebels und des Handgriffs von der Ruheposition in seine Betätigungsposition blockiert.In a preferred embodiment, the reversing lever has at least one locking element which engages with an accidental lock on occurrence of an external pulse as a result of a side impact and blocks a displacement of the reversing lever and the handle from the rest position to its actuated position.
Durch die Anordnung einer derartigen Unfallsperre kann ein ungewünschtes Verlagern des Umlenkhebels in die Betätigungsposition verbunden mit einem unerwünschten Freigeben des nicht verriegelten Kraftfahrzeugtürschlosses im Falle eines Unfalles vermieden werden. In diesem Fall kann eine derartige Unfallsperre in Folge des äußeren impulses in Folge eines Aufpralls, insbesondere bei einem Seitenaufprall, in Eingriff kommen und eine Verlagerung des Umlenkhebels von der Ruheposition in seine Betätigungsposition blockieren.By arranging such an accidental lock, an undesired displacement of the reversing lever into the actuation position can be associated with undesired release of the unlocked motor vehicle door lock in the vehicle Case of an accident can be avoided. In this case, such an accidental lock as a result of the external impulse due to an impact, in particular in a side impact, engage and block a displacement of the reversing lever from the rest position to its actuated position.
Dementsprechend sind die beweglichen Massen, etwaige Federkonstanten bei Anliegen einer Federlast und die Leichtgängigkeit der Gelenke der Kraftfahrzeugtürgriffanordnung und insbesondere der Unfallsperre so gewählt, dass bei Auftreten eines Impulses, beispielsweise in Folge eines Unfallgeschehens, die Unfallsperre so leichtgängig ist und eine entsprechende Trägheit aufweist, dass zunächst die Unfallsperre mit dem Rastelement an dem Umlenkhebel in Eingriff kommt und hierdurch den Umlenkhebel blockiert, bevor der Handgriff und der Umlenkhebel in Folge des Impulses aus der Ruheposition heraus verlagert werden könnten. Durch diese Unfallsicherung wird ein Öffnen der Tür aufgrund eines Aufpralls oder eines sonstigen Geschehens zuverlässig verhindert.Accordingly, the movable masses, any spring constants when a spring load and the ease of the joints of the motor vehicle door handle assembly and in particular the crash barrier are chosen so that when a pulse occurs, for example as a result of an accident, the crash barrier is so smooth and has a corresponding inertia that First, the crash barrier with the locking element on the bellcrank comes into engagement and thereby blocks the bellcrank, before the handle and the lever could be displaced out of the rest position due to the pulse. This accident protection reliable opening of the door due to an impact or other events is prevented.
Eine solche Unfallsperre kann insbesondere durch eine eine oder mehrere Ausnehmungen aufweisende Kreisscheibe gebildet sein, die In ihrer Ruheposition ein Verschwenken des Umlenkhebels in die Freigabeposition ermöglicht, indem eine an dem Umlenkhebel angeordnete Rastnase in eine Ausnehmung der Kreisscheibe einfährt. Im Falle eines äußeren Impulses wie bei einem Umfall des Fahrzeuges wird die Kreisscheibe durch Trägheitsmassen, die an entsprechenden Mitnehmern an der Kreisscheibe angreifen, in eine Blockierposition verdreht, sodass hierdurch der Umlenkhebel blockiert wird und das Türschloss nicht versehentlich freigegeben werden kann. Ferner ist dabei eine die Kreisscheibe in Richtung der Ruheposition drehende Rückstellfeder angeordnet.Such an accident lock can be formed, in particular, by a circular disc having one or more recesses, which in its rest position enables pivoting of the reversing lever into the release position, in that a latching lug arranged on the reversing lever enters a recess of the circular disc. In the case of an external impulse such as a fall of the vehicle, the circular disc is rotated by inertial masses which act on corresponding drivers on the circular disk in a blocking position, so that thereby the lever is blocked and the door lock can not be accidentally released. Further, while a circular disc in the direction of the rest position rotating return spring is arranged.
