Description
Die Erfindung betrifft Türinnengriffe für Kraftfahrzeuge. Der wertvolle Beitrag zum Stand der Technik
Aufgabe der vorliegenden Erfindung ist es, die Nachteile des Stands der Technik zu verbessern, insbesondere das Gewicht einer Türinnengriffvorrichtung mit Gegengewicht zu verringern. Die Aufgabe wird durch die unabhängigen Ansprüche gelöst. Vorteilhafte Weiterbildungen sind in den Unteransprüchen definiert.
Insbesondere wird die Aufgabe gelöst durch eine Türinnengriffvorrichtung für ein Fahrzeug zum Öffnen eines Fahrzeugtürschlosses, wobei die Vorrichtung einen Türinnengriff mit einem manuell zu ergreifenden Griffabschnitt aufweist, wobei der Türinnengriff einen ersten Verbindungsbereich aufweist, über welchen der Griffabschnitt im eingebauten Zustand der Vorrichtung gegenüber einer Fahrzeugtüre des Fahrzeugs um eine im Wesentlichen senkrecht zur Fahrbahnebene ausgerichtete Schwenkachse schwenkbar gelagert ist, und wobei der Türinnengriff einen zweiten Verbindungsbereich aufweist, an dem ein Gegengewichtelement angeordnet ist, wobei das Gegengewichtelement eingerichtet ist, bei Auftreten einer auf den Türinnengriff wirkenden Beschleunigung einer Öffnungskraft entgegenzuwirken, die aufgrund der Beschleunigung auf den Griffabschnitt wirkt, wobei das Gegengewichtelement über eine bewegliche Lagerung an dem zweiten Verbindungsbereich gelagert ist und eingerichtet ist, von einer Ruheposition in eine Sperrposition relativ zu dem Türinnengriff durch die Beschleunigung bewegt zu werden, wobei das Gegengewichtelement in der Sperrposition eine Schwenkbewegung des Türinnengriffs in einem vorgegebenem Bereich blockiert.
Object of the present invention is to improve the disadvantages of the prior art, in particular to reduce the weight of a door inner handle device with counterweight. The object is solved by the independent claims. Advantageous developments are defined in the subclaims.
In particular, the object is achieved by a door inner handle device for a vehicle for opening a vehicle door lock, wherein the device has a door inside handle with a handle portion to be grasped manually, wherein the door inner handle has a first connection region, via which the handle portion in the installed state of the device relative to a vehicle door of Vehicle about a substantially perpendicular to the road plane aligned pivot axis is pivotally mounted, and wherein the door inner handle has a second connection region on which a counterweight element is arranged, wherein the counterweight element is adapted to counteract when an acting on the door inner handle acceleration of an opening force acting on the grip portion due to the acceleration, wherein the counterweight element is mounted on the second connecting portion via a movable support and is adapted to be moved from a rest position to a locking position relative to the door inner handle by the acceleration, wherein the counterweight member in the locking position blocks a pivoting movement of the door inner handle in a predetermined range.
Hierdurch wird nicht nur der Schwenkbewegung durch die Gegengewichtsfunktion des Gegengewichtelements entgegenwirkt sondern es wird zudem und mit demselben Bauteil, nämlich dem Gegengewichtelement, eine Blockierfunktion bereitgestellt. Bei gleichem Bauteilaufwand wird somit ein doppelter Nutzen zur Erhöhung der Fahrzeugsicherheit erzielt so dass aufgrund dieses doppelten Nutzens das Eigengewicht des Gegengewichtelements und somit auch das Gesamtgewicht der Vorrichtung reduziert werden kann.As a result, not only is the pivoting movement counteracted by the counterweight function of the counterweight element, but in addition, and with the same component, namely the counterweight element, a blocking function is provided. With the same component cost, a double benefit is thus achieved in order to increase the vehicle safety, so that due to this double benefit, the dead weight of the counterweight element and thus also the total weight of the device can be reduced.
Eine Türinnengriffvorrichtung ist eine an der Innenseite einer Fahrzeugtürseite manuell zu betätigende Griffvorrichtung.An inside door handle device is a handle device to be manually operated on the inside of a vehicle door side.
Eine im Wesentlichen senkrecht zur Fahrbahnebene ausgerichtete Schwenkachse liegt bevorzugt vor, wenn die Achse sich um weniger als 45°, bevorzugt weniger als 20°, besonders bevorzugt weniger als 5° von der Senkrechten auf die Fahrbahnebene unterscheidet.A pivot axis aligned essentially perpendicular to the roadway plane is preferably present if the axis differs from the vertical to the roadway plane by less than 45 °, preferably less than 20 °, particularly preferably less than 5 °.
Die Lagerung des Türinnengriffs kann direkt an der Automobiltür erfolgen oder auch an einer an der Automobiltür angeordneten oder anzuordnenden Halterung. Der Türinnengriff weist eine geeignete Verbindung zu dem Türschloss auf, beispielsweise über einen Bowdenzug. Auf diese Weise kann durch ein Verschwenken des Türinnengriffs das Türschloss entriegelt und die Automobiltür geöffnet werden. Der Griffabschnitt kann beispielsweise länglich sein. Hierzu weist der Griff bevorzugt eine Ausdehnung senkrecht zur Schwenkachse auf, welche größer ist als die Ausdehnung entlang der Schwenkachse. Im Zweifel ist der Griffabschnitt der gesamte schwenkbare Bereich auf einer Seite der Schwenkachse. Der Türinnengriff kann aus einem Kunststoff bestehen. Er kann einstückig ausgebildet sein.The storage of the inside door handle can be done directly on the car door or on a arranged on the car door or bracket to be arranged. The door inner handle has a suitable connection to the door lock, for example via a Bowden cable. In this way, the door lock can be unlocked by pivoting the inside door handle and the automobile door can be opened. The handle portion may for example be elongated. For this purpose, the handle preferably has an extension perpendicular to the pivot axis, which is greater than the extent along the pivot axis. In doubt, the handle section is the entire pivoting Area on one side of the pivot axis. The inside door handle can be made of a plastic. He may be formed in one piece.
Eine bewegliche Lagerung an dem zweiten Verbindungsbereich ist eine Lagerung, welche eine Relativbewegung, bevorzugt mit relativer Schwerpunktverschiebung, zwischen Gegengewichtelement und Türinnengriff erlaubt, ansonsten jedoch den/die Freiheitsgrad/e zwischen Gegengewichtelement und Türinnengriff einschränkt und diese somit aneinander koppelt.A movable mounting on the second connecting region is a bearing which permits a relative movement, preferably with relative center of gravity displacement, between the counterweight element and the door inner handle, but otherwise limits the degree of freedom / e between the counterweight element and the door inner handle and thus couples them to one another.
Die Ruheposition ist die Position, welche das Gegengewichtelement im Normalfall (d.h. nicht bei einem Fahrzeugaufprall) einnimmt. Bevorzugt wird das Gegengewichtelement durch ein Federelement in der Ruheposition gehalten.The rest position is the position which the counterweight element normally assumes (i.e., not in a vehicle crash). Preferably, the counterweight element is held by a spring element in the rest position.
Das Gegengewichtelement blockiert in der Sperrposition eine Schwenkbewegung des Türinnengriffs in einem vorgegebenem Bereich, was bedeutet, dass der Türgriff im blockierten Fall einen kleineren möglichen Schwenkwinkel aufweist. Dieser Schwenkwinkel ist sinnvollerweise so eingeschränkt, dass ein Öffnen des Fahrzeugtürschlosses nicht möglich ist.The counterweight element blocks in the blocking position, a pivoting movement of the door inner handle in a predetermined range, which means that the door handle has a smaller possible pivot angle in the blocked case. This pivot angle is usefully limited so that an opening of the vehicle door lock is not possible.
In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung ist die bewegliche Lagerung eine Gelenklagerung mit einer Gelenkachse und die Gelenkachse ist im Wesentlichen parallel zur Schwenkachse ausgerichtet.In another embodiment of the present invention, the movable bearing is a hinge bearing having a hinge axis and the hinge axis is aligned substantially parallel to the pivot axis.
Hierdurch wird die Bewegung des Gegengewichtelements in die Sperrposition, welche eine Rotationsbewegung ist, zusätzlich durch die Schwenkbewegung des Griffabschnitts unterstützt. Im Wesentlichen parallel zur Schwenkachse ist die Gelenkachse bevorzugt dann, wenn sich die Achsrichtungen um weniger als 45°, bevorzugt weniger als 20°, besonders bevorzugt weniger als 5° voneinander unterscheiden. Der Schwerpunkt des Gegengewichtelements ist bevorzugt von der Gelenkachse beabstandet (exzentrisch).As a result, the movement of the counterweight element in the locking position, which is a rotational movement, additionally supported by the pivoting movement of the handle portion. The axis of articulation is preferably substantially parallel to the pivot axis when the axial directions differ from one another by less than 45 °, preferably less than 20 °, particularly preferably less than 5 °. The center of gravity of the counterweight element is preferably spaced from the hinge axis (eccentric).
In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung weist die Gelenklagerung mindestens ein Achselement auf, welches mit einem inversen Gelenkelement in Eingriff steht, wobei das mindestens eine Achselement integral mit dem Gegengewichtelement oder mit dem Türinnengriff ausgeformt ist.In a further embodiment of the present invention, the hinge bearing has at least one axle element which engages with an inverse hinge element, wherein the at least one axle element is formed integrally with the counterweight element or with the door inner handle.
Hierdurch werden Kosten und Montageaufwand gegenüber einer separaten Achse eingespart. Ein inverses Gelenkelement ist z.B. eine Nabe, welche als Bohrung in dem Türinnengriff realisiert sein kann. Bevorzugt ist das Achselement gegengewichtelementseitig und das inverse Gelenkelement türinnengriffseitig angeordnet.As a result, costs and installation costs are saved compared to a separate axis. An inverse hinge element is e.g. a hub, which can be realized as a bore in the door inner handle. The axle element is preferably arranged on the counterweight element side and the inverse joint element on the inside of the handle.
In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung weist das mindestens eine Achselement im Querschnitt eine Abflachung oder zwei sich gegenüberliegende Abflachungen auf und ist ansonsten rund und das inverse Gelenkelement weist einen Einführspalt auf, in welche das Achselement nur in einer vorgegebenen Rotationslage einführbar ist.In a further embodiment of the present invention, the at least one axle element in cross-section on a flat or two opposite flats and is otherwise round and the inverse hinge element has an insertion gap, in which the axle is insertable only in a predetermined rotational position.
Hierdurch ist eine leichte Montage der Achselemente durch einfaches zusammenschieben mittels der Abflachungen gegeben, gleichzeitig ist eine Sicherung gegen Auseinanderfallen durch den ansonsten runden Querschnitt gegeben. Die Abflachung/en ist/sind bevorzugt gerade. Zwei sich gegenüberliegende Abflachungen sind bevorzugt parallel zueinander. Bevorzugt wird das Gegengewichtelement zusammen mit dem/n Achselement/en durch die Einführspalte mit dem Türinnengriff zusammengeführt und dann verdreht. Bevorzugt ist die Rotationslage, die zum Verbinden (und somit auch Auseinanderbauen) der Gelenklagerung notwendig ist, im zusammengebauten Zustand oder im in die Fahrzeugtür eingebauten Zustand der Vorrichtung nicht mehr erreichbar, z.B. indem die Vorrichtung oder die Fahrzeugtür einen Anschlag aufweist, welcher ein Verdrehen der Gelenklagerung in diese Rotationslage verhindert.As a result, a simple assembly of the axle elements by simply push together by means of the flattening, while a backup against falling apart is given by the otherwise round cross-section. The flattening is preferably straight. Two opposing flats are preferably parallel to each other. Preferably, the counterweight element is brought together with the / n axle element / s by the Einführspalte with the inner door handle and then rotated. Preferably, the rotational position necessary for connecting (and thus disassembling) the hinge mounting is no longer attainable in the assembled state or in the state of the device installed in the vehicle door, e.g. in that the device or the vehicle door has a stop which prevents the joint bearing from rotating in this rotational position.
In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung weist die Gelenklagerung zwei Achselemente auf, die koaxial und voneinander beabstandet und integral mit dem Gegengewichtelement oder mit dem Türinnengriff ausgeformt sind, wobei zwischen den Achselementen eine Federelementhalterung ausgeformt ist, in welche ein Federelement koaxial mit der Gelenkachse einsetzbar ist.In a further embodiment of the present invention, the hinge bearing has two axle elements, which are coaxial and spaced apart and formed integrally with the counterweight element or with the door inner handle, wherein between the axle elements, a spring element holder is formed, in which a spring element is coaxial with the hinge axis ,
Hierdurch ist eine unkomplizierte Montage des Federelements gegeben und außerdem wird Gewicht gegenüber einer durchgehenden separaten Achse eingespart. Bevorzugt weist die Federelementhalterung zwei entlang der Gelenkachse gegenüberliegende, bevorzugt aufeinander zeigende Zapfen auf, die bevorzugt zur gleichen Seite hin, bevorzugt über mindestens ein Drittel, besonders bevorzugt mindestens die Hälfte der Zapfenstirnfläche, angeschrägt sind, was die Montage des Federelements nochmals vereinfacht. Das Federelement ist bevorzugt eine Spiralfeder.As a result, an uncomplicated assembly of the spring element is given and also weight is saved over a continuous separate axis. Preferably, the spring element holder on two opposite the hinge axis opposite, preferably facing each other pin, which preferably to the same side, preferably over at least one-third, more preferably at least the Half of the pin end face, beveled, which further simplifies the assembly of the spring element. The spring element is preferably a spiral spring.
In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung weist der Griffabschnitt eine Höhe HG entlang der Richtung der Schwenkachse auf und das Gegengewichtelement eine Höhe HW entlang der Richtung der Schwenkachse und die Höhe HW ist mindestens so groß wie ein Viertel, bevorzugt die Hälfte der Höhe HG, besonders bevorzugt ist HW genauso groß oder sogar größer als HG.In another embodiment of the present invention, the handle portion has a height HG along the direction of the pivot axis and the counterweight member has a height HW along the direction of the pivot axis and the height HW is at least as large as a quarter, preferably half the height HG, especially HW is preferably the same size or even larger than HG.
Durch diese Dimensionierung erhält das Gegengewichtelement ein hohes Volumen, so dass bei geeigneter Ausnutzung dieses Volumens auch eine ausreichende Masse des Gegengewichtelements zur Verfügung steht, um zum einen die Gegengewichtfunktion und zum anderen die Blockierfunktion vorteilhaft zu erfüllen. Je höher das Gewicht des Gegengewichtelements, desto stärker kann auch eine das Gegengewichtelement in die Ruheposition rückstellende Feder ausgelegt werden, so dass ein Klappern durch ungewollte Bewegungen des Gegengewichtelements minimiert wird. Der Fachmann findet hier einen Kompromiss zwischen guten Klappereigenschaften, Wirksamkeit der Funktion und dem niedrigen erwünschten Gesamtgewicht.As a result of this dimensioning, the counterweight element acquires a high volume, so that with suitable utilization of this volume, a sufficient mass of the counterweight element is also available in order, on the one hand, to advantageously fulfill the counterweight function and, on the other hand, the blocking function. The higher the weight of the counterweight element, the stronger a spring which resets the counterweight element to the rest position can be designed so that rattling due to unwanted movements of the counterweight element is minimized. One skilled in the art will find a compromise between good rattle properties, efficiency of function and low desired total weight.
Bevorzugt werden die Höhen jeweils am bezüglich der durch die Schwenkachse vorgegebenen Dimension untersten und obersten Punkt des Griffabschnitts und des Gegengewichtelements gemessen, jeweils als Projektion des Abstands dieser Punkte auf die durch die Schwenkachse vorgegebenen Dimension.Preferably, the heights are each measured at the lowest and uppermost point of the handle section and the counterweight element with respect to the dimension predetermined by the pivot axis, in each case as a projection of the distance of these points to the dimension predetermined by the pivot axis.
In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung weist der erste Verbindungsbereich zwei voneinander beabstandete Lagerelemente zur Lagerung des Türinnengriffs auf und das Gegengewichtelement erstreckt sich zwischen den Lagerelementen über den Mittelpunkt des Abstands der Lagerelemente hinüber.In a further embodiment of the present invention, the first connecting portion has two spaced-apart bearing elements for supporting the inner door handle and the counterweight element extends between the bearing elements over the center of the distance of the bearing elements over.
Hierdurch wird eine sehr vorteilhafte Bauraumausnutzung erhalten - das Gegengewichtelement kann somit einen möglichst großen Raum einnehmen und entsprechend groß dimensioniert werden, und somit wiederum über eine hohe Masse verfügen. Gleichzeitig ist ein im Wesentlichen symmetrischer Aufbau möglich, welcher die Kräfte vorteilhaft auf die verschiedenen Komponenten gleichmäßig verteilt.As a result, a very advantageous space utilization is obtained - the counterweight element can thus occupy the largest possible space and are dimensioned correspondingly large, and thus in turn have a high mass. At the same time a substantially symmetrical structure is possible, which distributes the forces evenly on the different components evenly.
Ein Lagerelement ist z.B. eine Bohrung im Türinnengriff, in welche eine fahrzeugtürseitige Achse gesteckt wird (oder andersherum: fahrzeugtürseitige Bohrung). Zwei Lagerelemente können auch z.B. zwei Zapfen sein. Die Lagerelemente ermöglichen die Schwenkbewegung des Türinnengriffs.A bearing element is, for example, a hole in the inside door handle, in which a vehicle door side axle is inserted (or vice versa: vehicle door bore side). Two Bearing elements can also be two pins, for example. The bearing elements allow the pivoting movement of the inside door handle.
In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung besteht das Gegengewichtelement aus einem Kunststoff. Die Erfindung umfasst dabei auch ein entsprechendes Verfahren zur Herstellung eines entsprechenden Gegengewichtelements aus Kunststoff sowie ein Verfahren zur Herstellung einer entsprechenden Türinnengriffvorrichtung.In a further embodiment of the present invention, the counterweight element consists of a plastic. The invention also encompasses a corresponding method for producing a corresponding counterweight element made of plastic as well as a method for producing a corresponding door inner handle device.
Hierdurch werden Kosten bei der Produktion eingespart. Dies ist insbesondere erst durch die entsprechende Dimensionierung des Gegengewichtelements (Erstreckung des Gegengewichtelements über den Mittelpunkt sowie Mindesthöhe HW) möglich, da Kunststoff ansonsten zu wenig spezifische Masse aufweist, um die Gegengewichtsfunktion und die Blockierfunktion vorteilhaft zu erfüllen.This saves costs during production. This is possible in particular only by the corresponding dimensioning of the counterweight element (extension of the counterweight element via the center and minimum height HW), since plastic otherwise has too little specific mass to advantageously fulfill the counterweight function and the blocking function.
In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung ist bzw. wird das Gegengewichtelement mittels eines Mehrkomponenten-Spritzgussverfahrens aus mindestens einem harten und einem weichen jeweils spritzgegossenen Material hergestellt und das Gegengewichtelement liegt in seiner Ruheposition an einem Anschlagbereich des Türinnengriffs an, wobei der Bereich des Gegengewichtelements, welcher an dem Anschlagbereich anliegt, eine Oberfläche aus dem weichen Material aufweist, welche im Kontakt mit dem Anschlagbereich steht, wenn sich das Gegengewichtelement in seiner Ruheposition befindet.In a further embodiment of the present invention, the counterweight element is made by means of a multi-component injection molding of at least one hard and one soft injection-molded material and the counterweight element is in its rest position against a stop region of the door inner handle, wherein the region of the counterweight element abutting against the stopper area, having a surface of the soft material which is in contact with the stopper area when the counterweighting element is in its rest position.
Hierdurch werden Klappergeräusche minimiert. Das Gegengewichtelement kann somit optimal aus gewichtsgebenden (hartes Material) und dämpfenden (weiches Material) Bestandteilen in einem Spritzgussverfahren hergestellt werden.As a result, rattling noises are minimized. The counterweight element can thus be optimally made of weight-giving (hard material) and damping (soft material) components in an injection molding process.
In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung weist das Gegengewichtelement umspritzte Metallteile, insbesondere eine oder mehrere Metallkugeln oder Metallzylinder, auf bzw. werden solche Teile bei der Herstellung umspritzt.In a further embodiment of the present invention, the counterweight element comprises overmolded metal parts, in particular one or more metal balls or metal cylinders, or such parts are encapsulated in the production.
Hierdurch kann falls notwendig das Gewicht erhöht werden und insbesondere bei Verwendung von Metallkugeln/Metallzylindern ist dies sehr kostengünstig, da es sich bei der Metallkugel bzw. dem Metallzylinder um ein standardisiertes Bauteil handelt, welches für unterschiedlichste Türinnengriffe eingesetzt werden kann.As a result, if necessary, the weight can be increased and in particular when using metal balls / metal cylinders, this is very cost-effective, since it is a standardized component in the metal ball or the metal cylinder, which can be used for a variety of door inner handles.
In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung liegt das Gegengewichtelement in seiner Ruheposition an einem Anschlagbereich des Türinnengriffs an, wobei zumindest der Anschlagbereich des Türinnengriffs mittels eines Mehrkomponenten-Spritzgussverfahrens aus mindestens einem harten und einem weichen jeweils spritzgegossenen Material hergestellt ist, wobei der Anschlagbereich eine Oberfläche aus dem weichen Material aufweist, welche im Kontakt mit dem Gegengewichtelement steht, wenn sich das Gegengewichtelement in seiner Ruheposition befindet. Die Erfindung umfasst dabei auch ein entsprechendes Verfahren zur Herstellung eines entsprechenden Türinnengriffs oder Anschlagbereichs des Türinnengriffs aus Kunststoff sowie ein Verfahren zur Herstellung einer entsprechenden Türinnengriffvorrichtung.In a further embodiment of the present invention, the counterweight element is in its rest position against a stop region of the door inner handle, wherein at least the stop region of the door inner handle is made by means of a multi-component injection molding process of at least one hard and one soft injection-molded material, wherein the stopper area of a surface the soft material which is in contact with the counterweight element when the counterweight element is in its rest position. The invention also encompasses a corresponding method for producing a corresponding inside door handle or stop area of the inside door handle made of plastic as well as a method for producing a corresponding inside door handle device.
Hierdurch werden alternativ oder zusätzlich zum mehrkomponenten-gespritzten Gewichtelement Klappergeräusche minimiert. Die aus weichem Material bestehende Oberfläche des Anschlagbereichs des Türinnengriffs ist bevorzugt die bezüglich des ersten Verbindungsbereichs jenseits des Griffabschnitts liegende Stirnseite des Türinnengriffs.As a result, rattling noises are minimized as an alternative or in addition to the multi-component molded weight element. The soft material surface of the abutment portion of the door inner handle is preferably located with respect to the first connection region beyond the handle portion end face of the inner door handle.
In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung weist die Vorrichtung zur Ausbildung der Sperrposition des Gegengewichtelements mindestens ein Blockierelement sowie ein dazugehöriges Blockiergegenelement auf.In a further exemplary embodiment of the present invention, the device for forming the blocking position of the counterweight element has at least one blocking element and an associated blocking counter element.
Das Blockierelement ist bevorzugt als Stift ausgebildet. Bevorzugt ist dieser an dem Gegengewichtelement angeordnet, besonders bevorzugt einstückig mit dem Gegengewichtelement ausgeformt. Das Blockiergegenelement ist bevorzugt eine Kontur, welche eingerichtet ist, den Stift zumindest bereichsweise zu führen. Sie ist bevorzugt an einer Halterung, welche bevorzugt Teil der Türinnengriffvorrichtung ist und an welcher der Türinnengriff schwenkbar gelagert ist, aus- oder angeformt.The blocking element is preferably designed as a pin. This is preferably arranged on the counterweight element, particularly preferably integrally formed with the counterweight element. The blocking counter-element is preferably a contour which is set up to guide the pin at least in regions. It is preferably on a holder, which is preferably part of the door inner handle device and on which the door inner handle is pivotally mounted, formed or molded.
In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung sind das Blockierelement und das Blockiergegenelement durch einen Stift und eine Kontur gebildet, wobei die Kontur eingerichtet ist, den Stift zumindest in einem vorgegebenen Bewegungsteilbereich einer Relativbewegung zwischen der Kontur und dem Stift zu führen und dessen Bewegung somit zu begrenzen, wobei die Kontur bezogen auf die Schwenkachse radial innerhalb des Stifts angeordnet ist, wenn sich das Gegengewichtelement in seiner Ruheposition befindet, und die Kontur ein Tal aufweist, welches sich (von der Talsohle ausgehend nach radial - bezüglich der Schwenkachse - außen und) zur Innenseite der Vorrichtung hin öffnet.In a further embodiment of the present invention, the blocking element and the blocking counter element are formed by a pin and a contour, wherein the contour is adapted to guide the pin at least in a predetermined movement portion of a relative movement between the contour and the pin and thus limit its movement wherein the contour is located radially inwardly of the pin with respect to the pivot axis when the counterweight element is in its rest position and the contour has a valley which starting (from the bottom, radially - with respect to the pivot axis - outside and) towards the inside of the device opens.
Hierdurch wird eine Verstärkung der Fixierung des Gegengewichtelements in der Sperrposition durch eine die durch die Beschleunigung eventuell noch auftretende Griffverschwenkung erreicht, da durch die Griffverschwenkung die Bewegung des Gegengewichtelements in Richtung des Anschlags der Sperrposition (Talsohle der Kontur) unterstützt bzw. erzwungen wird. Die Innenseite der Vorrichtung ist bevorzugt die Seite, welche dem Fahrzeuginnenraum im eingebauten Zustand zugewandt ist.As a result, a gain of the fixation of the counterweight element in the locked position by a possibly occurring by the acceleration Griffverschwenkung is achieved, as supported by the Griffverschwenkung the movement of the counterweight element in the direction of the stop of the locking position (bottom of the contour) or enforced. The inside of the device is preferably the side which faces the vehicle interior in the installed state.
Bevorzugt ist der Bereich der Kontur bzw. die Flanke des Tals, entlang welcher der Stift bei einer Bewegung des Gegengewichtelements zum Anschlag der Sperrposition wandert, in einem Winkel zwischen 5° und 70°, besonders bevorzugt im Mittel 30° bis 40° zur Fahrzeugtürebene in Richtung Fahrzeuginnenbereich schräg verlaufend. Bevorzugt weist die Kontur eine in die Talsohle der Kontur übergehenden konvexe Krümmung auf, was eine sehr vorteilhafte Unterstützung in Richtung sperrpositionsseitiger Anschlag (Talsohle) erzeugt.Preferably, the region of the contour or the flank of the valley along which the pin moves during a movement of the counterweight element to stop the blocking position, at an angle between 5 ° and 70 °, more preferably on average 30 ° to 40 ° to the vehicle door level Towards the vehicle interior oblique. The contour preferably has a convex curvature which transitions into the bottom of the contour, which produces a very advantageous support in the direction of the stop position (bottom of the valley) on the blocking position.
In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung weist das Gegengewichtelement mindestens zwei Blockierelemente auf, welche, wenn sich das Gegengewichtelement in der Sperrposition befindet, jeweils mit einem Blockiergegenelement einen Sperrkontakt bilden.In a further embodiment of the present invention, the counterweight element has at least two blocking elements which, when the counterweight element is in the blocking position, each form a blocking contact with a blocking counter element.
Hierdurch wird eine höhere Sicherheit der Blockierfunktion erreicht.As a result, a higher security of the blocking function is achieved.
In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung liegen sich zwei der Blockierelemente auf zwei Seiten des Gegengewichtelements gegenüber.In a further embodiment of the present invention, two of the blocking elements face each other on two sides of the counterweight element.
Hierdurch wird die Sicherheit noch weiter erhöht, da eine gleichmäßigere Verteilung der Sperrbelastung auf die beiden Blockierelemente erfolgen kann. Die Blockierelemente sind bevorzugt an den das Gegengewichtelement bezüglich der Gelenkachsenrichtung stirnseitig abschließenden Seiten angeordnet.As a result, the security is further increased, since a more uniform distribution of the blocking load can be made on the two blocking elements. The blocking elements are preferably arranged on the sides which terminate the counterweight element with respect to the joint axis direction.

In an accident, especially in a side impact, an acceleration acts on the
Hierdurch dient das Gegengewichtelement 20 einerseits als Gegengewicht, andererseits als Fliehgewicht, und somit wird mit ein und demselben gewichtsgebenden Bauteil eine doppelte Wirkung erzielt, so dass das Gegengewichtelement 20 insgesamt leichter ausgestaltet werden kann, da die benötigte Wirkung nicht mehr nur auf die Funktion als Gegengewicht zurückgeführt wird sondern auch, bevorzugt sogar in einem überwiegenden Anteil, auf die Blockierfunktion.As a result, the
Durch die annähernde Achsparallelität der Achsen 12 und 42 unterstützt die Drehbewegung des Türinnengriffs 10 die relative Drehung des Gegengewichtelements 20 relativ zum Türinnengriff 10 in besonders vorteilhaft hohem Maße. Ferner ist eine sehr vorteilhafte Ausnutzung des Bauraums gegeben, so dass das Gewicht ein großes Volumen einnehmen kann und somit die Möglichkeit gegeben ist, auch andere günstigere oder leichter formbare Materialien wie z.B. Kunststoff zu verwenden.Due to the approximate axis parallelism of the
Zur Ausbildung der Sperrposition des Gegengewichtelements 20 weist die Vorrichtung 1 zwei Blockierelemente 21.1, 21.2 sowie zwei dazugehörige Blockiergegenelemente (nicht gezeigt) auf. Die Blockierelemente 21.1, 21.2 liegen sich auf zwei Seiten des Gegengewichtelements 20 gegenüber, hier bevorzugt auf den das Gegengewichtelement bezüglich der Gelenkachsenrichtung stirnseitig abschließenden Seiten. Wenn sich das Gegengewichtelement (20) in der Sperrposition befindet, bilden die Blockierelemente 21.1, 21.2 jeweils mit dem entsprechenden Blockiergegenelement einen Sperrkontakt. Die Blockierelemente 21.1, 21.2 sind hier als bevorzugte Stifte ausgebildet, die hier bevorzugt einstückig mit dem Gegengewichtelement ausgeformt sind.To form the locking position of the
Sofern keine durch einen Aufprall wirkende Beschleunigung vorhanden ist und der Griffabschnitt 11 manuell zum Fahrzeuginnenraum hin verschwenkt wird, schwenkt das Gegengewichtelement 20 mit dem Türinnengriff 10 (Blockpfeile) - bei diesem Beispiel hier bewegen sich dabei die Blockierelemente 21.2, 21.1 jeweils frei durch eine Nut in der Halterung 50. Bei einem Seitenaufprall erzeugt eine Querbeschleunigung, welche größer ist als das Rückstellmoment des Federelements 46, ein Verschwenken des Gegengewichtelements 20 relativ zum Türinnengriff 10 (einfacher Pfeil an der unteren Kontur 51.2), so dass eine Schwenkbewegung des Türgriffes um die Schwenkachse 12 durch die an den Konturen der Blockiergegenelemente 51.1, 51.2 anschlagenden Stifte bzw. Blockierelemente 21.2, 21.1 begrenzt wird.If there is no acceleration acting through an impact and the
Hiermit wurde eine besonders vorteilhafte Türinnengriffvorrichtung bereitgestellt. Durch die Anordnung eines Gegengewichtelements auf dem schwenkbaren Türinnengriff jenseits der Schwenklagerung wird eine Gewichtskompensation erreicht, so dass der Schwerpunkt näher zum Schwenklagerpunkt verlagert ist, wobei zusätzlich durch die bewegliche Lagerung des Gegengewichtelement eine Blockierfunktion des Gegengewichtelements gegeben ist und somit die Gegengewichtfunktion reduziert werden kann. Durch optimale Bauraumausnutzung ist eine günstige Herstellung aus Spritzguss-Kunststoff möglich und durch weitere Maßnahmen wie achsstiftloses Design sowie Zweikomponenten-Herstellungsverfahren werden weiterhin Kosten und Gewicht reduziert sowie Robustheit und Komfort erhöht.
