Kraftfahrzeugtürscharniere der eingangs genannten Art sind in vielfältigen Ausgestaltungen aus dem Stand der Technik bekannt. Sie erlauben die Anbindung einer Fahrzeugtür an eine Fahrzeugkarosserie, wobei die integrierten Feststelleinheiten dazu dienen, die Kraftfahrzeugtür in vorbestimmten Winkelpositionen zu sichern, so dass auf separate Feststeller verzichtet werden kann. Die Feststelleinheiten gattungsgemäßer Kraftfahrzeugtürscharniere weisen dabei in der Regel festgelegte Rastwinkel auf, in denen die Kraftfahrzeugtür gegenüber einem ungewollten Weiterverschwenken gesichert ist.Motor vehicle door hinges of the type mentioned are known in various configurations from the prior art. They allow the connection of a vehicle door to a vehicle body, wherein the integrated locking units serve to secure the vehicle door in predetermined angular positions, so that can be dispensed with separate lock. The locking units of generic motor vehicle door hinges generally have fixed locking angles in which the motor vehicle door is secured against undesired further pivoting.
Auch existieren in geringerem Umfang Kraftfahrzeugtürscharniere, bei denen die Feststelleinheit eine stufenlose Arretierung der Kraftfahrzeugtür erlaubt, wodurch die Möglichkeit besteht, die Kraftfahrzeugtür in beliebigen, vom Fahrzeugnutzer bestimmten Öffnungswinkeln festzulegen. Neben passiv wirkenden stufenlosen Feststelleinheiten, d. h. solchen Feststelleinheiten, die die durch einen Benutzer zu Beginn einer Verschwenkbewegung der Tür eingeleitete Bewegungsenergie dazu nutzen, um eine bestehende, bei Beendigung einer Schwenkbewegung der Tür selbsttätig eintretende Arretierung aufzuheben, existiert ferner eine Gruppe von Kraftfahrzeugtürscharnieren mit stufenloser Arretierung, bei denen die Feststelleinheit durch eine separate Betätigungseinheit gesteuert wird.Also, to a lesser extent, there are motor vehicle door hinges in which the locking unit allows stepless locking of the motor vehicle door, whereby it is possible to fix the motor vehicle door at any desired opening angle determined by the vehicle user. In addition to passive acting stepless detection units, d. H. Such locking units, which use the initiated by a user at the beginning of a pivotal movement of the door kinetic energy to cancel an existing, upon termination of a pivoting movement of the door automatically entering detent, there is also a group of motor vehicle door hinges with stepless lock in which the locking unit by a separate actuator is controlled.
Bei den Kraftfahrzeugtürscharnieren mit eigenständigem Betätigungssystem zur Steuerung der Feststelleinheit werden in der Regel jedoch komplexe Systeme eingesetzt, um in Abhängigkeit vom Betriebszustand die Arretierung aufzubauen bzw. aufzulösen. Derartige Systeme weisen jedoch den Nachteil auf, dass sie einen großen Bauraum beanspruchen und äußerst kostenintensiv sind.In the motor vehicle door hinges with independent operating system for control However, the locking unit complex systems are usually used to build up or release the lock depending on the operating condition. However, such systems have the disadvantage that they require a large amount of space and are extremely expensive.
Ein gattungsgemäßes Kraftfahrzeugtürscharnier ist ferner aus der
Der Erfindung liegt die Aufgabe zugrunde, ein Kraftfahrzeugtürscharnier mit einer Feststelleinheit bereitzustellen, welche eine zuverlässige Arretierung einer mit dem Kraftfahrzeugtürscharnier verbundenen Fahrzeugtür unter wechselnden Bedingungen ermöglicht.The invention has for its object to provide a motor vehicle door hinge with a locking unit, which allows reliable locking of a vehicle door connected to the motor vehicle door hinge under changing conditions.
Die Erfindung löst die Aufgabe durch ein Kraftfahrzeugtürscharnier mit den Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.The invention solves the problem by a motor vehicle door hinge with the features of
Das erfindungsgemäße Kraftfahrzeugtürscharnier weist eine Türkonsole, welche mit der Fahrzeugtür verbindbar ist, sowie eine mit der Fahrzeugkarosserie verbindbare Säulenkonsole auf, wobei die Türkonsole und die Säulenkonsole - um eine Verschwenkbarkeit einer mit dem Kraftfahrzeugtürscharnier verbundenen Kraftfahrzeugtür zu gewährleisten - über einen Scharnierstift gelenkig miteinander verbunden sind. Der Scharnierstift ist dabei entweder mit der Säulenkonsole oder der Türkonsole verdrehfest verbunden und an der anderen Konsole gelenkig angeordnet.The motor vehicle door hinge according to the invention has a door bracket, which is connectable to the vehicle door, and connectable to the vehicle body pillar console, the door console and the pillar bracket - to ensure a pivoting of an associated with the motor vehicle door hinge motor vehicle door - are hingedly connected to each other via a hinge pin. The hinge pin is connected either rotationally fixed to the column console or the door bracket and hinged to the other console.
Zur Arretierung einer mit dem Kraftfahrzeugtürscharnier verbundenen Kraftfahrzeugtür weist die Feststelleinheit des erfindungsgemäßen Kraftfahrzeugtürscharniers ein Arretierungselement auf, welches an der Konsole, die gelenkig mit dem Scharnierstift verbunden ist, festgelegt ist. Eine Festlegung der Arretierung des Kraftfahrzeugtürscharniers in Positionen zwischen einer maximalen Öffnungslage der Kraftfahrzeugtür und deren Schließlage, wobei die Positionen durch den Schwenkwinkelbereich der Türkonsole gegenüber der Säulenkonsole bestimmt sind, erfolgt durch eine Betätigung des Arretierungselements, das gegenüber dem Scharnierstift zwischen einer Blockierlage und einer Freigabeposition verstellbar ist. In der Blockierlage verhindert oder hemmt das Arretierungselement aufgrund seines Zusammenwirkens mit dem Scharnierstift eine ungewollte Verschwenkung der Tür. Das Arretierungselement wirkt dabei direkt mit dem Scharnierstift zusammen und hemmt zumindest die Verschwenkung, so dass ein erhöhtes Betätigungsmoment erforderlich ist. In der Freigabeposition befindet sich das Arretierungselement hingegen in einer Position gegenüber dem Scharnierstift, in der eine Verschwenkung der Kraftfahrzeugtür mit einem geringen Betätigungsmoment erfolgen kann. Inwieweit in der Freigabeposition und Blockierlage der Einfluss des Arretierungselements besteht ist frei wählbar, wobei grundsätzlich auch eine Verstellung vorgesehen sein kann, bei der das Arretierungselement zwischen einer die Türkonsole vollständig festlegenden sowie einer mit dem Scharnierstift völlig außer Eingriff befindlichen Position bewegt werden kann, in der das Arretierungselement keinen Einfluss auf das Betätigungsmoment ausübt. Nachdem das Arretierungselement auch in beliebigen Zwischenpositionen angeordnet werden kann, ist eine individuelle Festlegung des weitestgehend durch das Arretierungsmittel bestimmten Betätigungsmoments in einfacher Weise möglich.For locking a motor vehicle door connected to the motor vehicle door hinge, the locking unit of the motor vehicle door hinge according to the invention has a locking element, which is fixed to the bracket, which is pivotally connected to the hinge pin. A determination of the locking of the motor vehicle door hinge in positions between a maximum opening position of the motor vehicle door and its closed position, wherein the positions are determined by the pivot angle range of the door bracket relative to the column console, is effected by an actuation of the locking element which is adjustable relative to the hinge pin between a blocking position and a release position. In the blocking position, the locking element prevents or inhibits unwanted pivoting of the door due to its interaction with the hinge pin. The locking element acts directly with the hinge pin and inhibits at least the pivoting, so that an increased operating torque is required. In the release position, however, the locking element is in a position relative to the hinge pin, in which a pivoting of the motor vehicle door can be done with a low operating torque. To what extent in the release position and blocking position of the influence of the locking element is arbitrary, in principle, an adjustment can be provided in which the locking element between the door bracket completely defining and a completely out of engagement with the hinge pin position can be moved in the the locking element exerts no influence on the actuating torque. After the locking element can be arranged in any intermediate positions, an individual determination of the largely determined by the locking means actuating torque in a simple manner possible.
Zur Verstellung des Arretierungselements zwischen der Blockierlage und der Freigabeposition dient eine Stelleinheit, wobei die Stelleinheit erfindungsgemäß ihrerseits mit einer diese antreibenden sowie den Betriebszustand der Fahrzeugtür erfassenden Steuerungseinheit verbunden ist. Die Stelleinheit dient somit dazu, das Arretierungselement in die gewünschte - vom Betriebszustand der Fahrzeugtür abhängige - Position zu verstellen. Wesentliche Betriebszustände sind dabei zum einen die Ermittlung einer Schwenkbewegung der Fahrzeugtür sowie der bestehende Schwenkwinkel der Türkonsole gegenüber der Säulenkonsole aus dem sich der Öffnungswinkel der Tür ergibt. Im Falle einer Schwenkbewegung bzw. einer Betätigung der Tür ausgehend von einer arretierten Position dient die Stelleinheit dazu, das Arretierungselement derart zu positionieren, dass eine Schwenkbewegung der Kraftfahrzeugtür weitestgehend mit einem geringen Betätigungsmoment erfolgen kann. Im Falle eines Stillstands der Fahrzeugtür dient die Stelleinheit dazu, das Arretierungselement in Richtung auf die Blockierlage zu verstellen, um so eine ungewollte Verstellung der Kraftfahrzeugtür aus der eingestellten Position zu verhindern. Die Verstelleinheit wird dabei über die Steuerungseinheit betätigt, welche darüber hinaus auch zur Erfassung der Betriebszustände der Kraftfahrzeugtür ausgebildet ist.To adjust the locking element between the blocking position and the release position is an actuating unit, wherein the adjusting unit according to the invention in turn connected to this driving and detecting the operating state of the vehicle door control unit. The actuator thus serves to adjust the locking element in the desired - dependent on the operating state of the vehicle door - position. Essential operating conditions are, on the one hand, the determination of a pivoting movement of the vehicle door and the existing pivoting angle of the door console opposite the pillar console, which results in the opening angle of the door. In the case of a pivoting movement or an actuation of the door, starting from a locked position, the setting unit serves to position the locking element in such a way that a pivoting movement of the motor vehicle door can largely take place with a low actuating torque. In the case of a stoppage of the vehicle door, the adjusting unit serves to adjust the locking element in the direction of the blocking position, so as to prevent unintentional adjustment of the motor vehicle door to prevent from the set position. The adjusting unit is actuated via the control unit, which is also designed to detect the operating states of the motor vehicle door.
Die Verwendung der erfindungsgemäßen Steuerungseinheit erlaubt es, die von der Feststelleinheit erzeugte Haltekraft unabhängig vom Öffnungswinkel der raftfahrzeugtür festzulegen. Somit können identischen Öffnungswinkeln beliebig viele, allein vom Betriebszustand der Fahrzeugtür abhängige Haltekräfte zugeordnet werden.The use of the control unit according to the invention makes it possible to set the holding force generated by the locking unit regardless of the opening angle of the raftfahrzeugtür. Thus, identical opening angles can be assigned as many, depending solely on the operating state of the vehicle door holding forces.
Das erfindungsgemäße Kraftfahrzeugtürscharnier zeichnet sich durch seinen besonders hohen Bedienkomfort aus, wobei die Verwendung einer mit dem Arretierungselement verbundenen Stelleinheit, welche durch eine die Betriebszustände erfassenden Steuerungseinheit gesteuert wird, einen zuverlässigen Betrieb gewährleistet. Darüber hinaus lässt sich das erfindungsgemäße Kraftfahrzeugtürscharnier über die Steuerungseinheit an unterschiedliche herstellerspezifische Vorgaben anpassen, wobei dies über eine verschiedenartige Ansteuerung der Verstelleinheit erfolgen kann. Über die Steuerungseinheit können in einfacher Weise den verschiedenen Betriebszuständen einer mit dem Kraftfahrzeugtürscharnier verbundenen Fahrzeugtür kundenspezifische Zustände der Feststelleinheit zugeordnet werden.The motor vehicle door hinge according to the invention is distinguished by its particularly high operating comfort, the use of an actuating unit connected to the locking element, which is controlled by a control unit which detects the operating states, ensuring reliable operation. In addition, the motor vehicle door hinge according to the invention can be adapted via the control unit to different manufacturer-specific specifications, wherein this can be done via a different type of control of the adjustment. By means of the control unit, customer-specific states of the locking unit can be assigned in a simple manner to the various operating states of a vehicle door connected to the motor vehicle door hinge.
Der Antrieb der Stelleinheit erfolgt erfindungsgemäß über die Steuerungseinheit, wobei die konkrete Ausgestaltung grundsätzlich frei wählbar ist. So kann die Steuerungseinheit bspw. eine pneumatisch und/oder hydraulisch wirkende Antriebseinheit aufweisen. Gemäß der Erfindung weist die Steuerungseinheit eine Antriebseinheit auf, insbesondere eine elektromechanische Antriebseinheit, die derart mit der Stelleinheit verbunden ist, dass eine Betätigung der Antriebseinheit eine Verstellung eines mit dem Arretierungselement in Eingriff befindlichen Stellelements der Stelleinheit zwischen einer der Freigabeposition und einer der Blockierlage zugeordneten Stellung bewirkt. Das Stellelement bestimmt somit in Abhängigkeit von seiner Position die durch das Arretierungselement bewirkte Haltekraft. Die Antriebseinheit dient dazu, die Stelleinheit anzutreiben und damit eine Verstellung des Stellelements zu bewirken, so dass dieses zumindest zwischen den Stellungen verstellt wird, welche der Freigabeposition und der Blockierlage des Arretierungselements zugeordnet sind.The drive of the actuator is carried out according to the invention via the control unit, the specific embodiment is basically freely selectable. For example, the control unit can have a pneumatic and / or hydraulic drive unit. According to the invention, the control unit has a drive unit, in particular an electromechanical drive unit, which is connected to the setting unit such that an actuation of the drive unit is an adjustment of an actuating element engaged with the locking element of the setting unit between a position associated with the release position and a blocking position causes. The actuating element thus determines, depending on its position, the holding force caused by the locking element. The drive unit serves to drive the actuating unit and thus to effect an adjustment of the actuating element, so that this is adjusted at least between the positions which are associated with the release position and the blocking position of the locking element.
Die Anordnung einer Antriebseinheit an einer Steuerungseinheit ermöglicht eine besonders kompakte Bauweise, wobei insbesondere eine elektromechanische Antriebseinheit eine kostengünstige sowie zuverlässige Möglichkeit zum Antrieb der Stelleinheit bietet.The arrangement of a drive unit to a control unit allows a particularly compact design, in particular, an electromechanical drive unit provides a cost effective and reliable way to drive the actuator.
Nach der Erfindung ist vorgesehen, dass die Antriebseinheit einen mit dem Stellelement in Eingriff befindlichen Antriebsmotor, insbesondere Elektromotor aufweist. Die Verwendung eines Elektromotors eignet sich in besonderer Weise zur Verbindung mit dem Stellelement, nachdem hierzu lediglich eine Kopplung der Abtriebswelle des Antriebsmotors mit dem Stellelement erforderlich ist. Das Stellelement lässt sich durch den Antriebsmotor besonders exakt und schnell verlagern, so dass eine besonders schnelle Anpassung des Kraftfahrzeugtürscharniers an die jeweiligen Betriebszustände möglich ist.According to the invention, it is provided that the drive unit has a drive motor, in particular an electric motor, which is in engagement with the actuating element. The use of an electric motor is particularly suitable for connection to the control element, after this only a coupling of the output shaft of the drive motor is required with the actuator. The adjusting element can be displaced particularly accurately and quickly by the drive motor, so that a particularly rapid adaptation of the motor vehicle door hinge to the respective operating states is possible.
Neben dem Antrieb der Stelleinheit dient die Steuereinheit darüber hinaus zur Erfassung des Betriebszustands der Fahrzeugtür. Wie bereits eingangs dargestellt, sind die entsprechende Ausgestaltung der Steuerungseinheit sowie die Art der zu erfassenden Betriebszustände grundsätzlich frei wählbar. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung weist die Steuerungseinheit jedoch Mittel zur Erfassung des Schwenkwinkels und/oder einer Schwenkbewegung der Türkonsole gegenüber der Säulenkonsole auf. Die Erfassung der unmittelbar mit der Schwenkbewegung einer Fahrzeugtür einhergehenden Schwenkbewegung der Türkonsole gegenüber der Säulenkonsole erlaubt es festzustellen, ob die Tür bewegt wird oder eine Schwenkbewegung bereits beendet und die Tür in der gewünschten Halteposition angeordnet wurde. Die Erfassung des Schwenkwinkels erlaubt es ferner, die Türposition exakt zu erfassen, so dass die Möglichkeit besteht, schwenkwinkelabhängige Positionen des Arretierungselements vorzusehen. Darüber hinaus erlaubt die derart ausgebildete Steuerungseinheit durch eine Bewegungserfassung die Erkennung einer beabsichtigten Verschwenkung der Tür, wobei die Festlegung der zu erfolgenden Verstellung der Stelleinheit grundsätzlich frei wählbar ist.In addition to the drive of the control unit, the control unit also serves to detect the operating state of the vehicle door. As already mentioned, the corresponding configuration of the control unit and the type of operating states to be detected are basically freely selectable. According to a particularly advantageous embodiment of the invention, however, the control unit has means for detecting the pivoting angle and / or a pivoting movement of the door bracket relative to the column console. The detection of the pivoting movement of the door panel directly opposite the column console, which is directly associated with the pivoting movement of a vehicle door, makes it possible to determine whether the door has been moved or has already completed a pivotal movement and the door has been arranged in the desired holding position. The detection of the pivot angle also makes it possible to accurately detect the door position, so that there is the possibility to provide pivoting angle-dependent positions of the locking element. In addition, the control unit formed in this way allows the detection of an intended pivoting of the door by means of a movement detection, the determination of the adjustment of the control unit to be carried out being basically freely selectable.
Die Erfassung des Schwenkwinkels kann in beliebiger Weise erfolgen. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist das Mittel zur Erfassung des Schwenkwinkels jedoch durch einen Signalaufnehmer gebildet, der mit einem an dem Scharnierstift angeordneten Signalgeber in Wirkverbindung befindlich ist. Gemäß dieser Ausgestaltung der Erfindung lässt sich der Schwenkwinkel unmittelbar im Bereich des Feststellers ermitteln, so dass eine besonders kompakte Bauweise möglich ist. Nachdem darüber hinaus die Schwenkwinkelerfassung unmittelbar an den gegeneinander verschwenkten Teilen erfolgt, ist eine sehr genaue Erfassung des tatsächlichen Schwenkwinkels möglich.The detection of the swivel angle can be done in any way. According to a particularly advantageous embodiment of the invention, however, the means for detecting the pivoting angle is formed by a signal sensor, which is located in operative connection with a arranged on the hinge pin signal generator. According to this embodiment of the Invention, the pivot angle can be determined directly in the area of the arrester, so that a particularly compact design is possible. In addition, since the swivel angle detection takes place directly on the mutually pivoted parts, a very accurate detection of the actual swivel angle is possible.
Die Verarbeitung der erfassten Betriebszustände mit der auch die Ansteuerung der die Stelleinheit antreibenden Antriebseinheit einhergeht, kann grundsätzlich an beliebiger Stelle, bspw. durch separate Regeleinrichtungen erfolgen. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung steuert die Steuerungseinheit die Antriebseinheit jedoch in Abhängigkeit vom Schwenkwinkel und/oder einer Schwenkbewegung der Türkonsole gegenüber der Säulenkonsole an, wobei bei einem Stillstand der Türkonsole gegenüber der Säulenkonsole die Antriebseinheit das Stellelement in Richtung auf die der Blockierlage zugeordnete Stellung und bei einer Verschwenkung der Türkonsole gegenüber der Säulenkonsole in Richtung auf die der Freigabeposition zugeordnete Stellung verlagert. Somit erlaubt es eine entsprechende Ausgestaltung der Steuerungseinheit auf zusätzliche Verarbeitungs- oder Regelungseinheiten zu verzichten. Die Steuerungseinheit kann unmittelbar mit der Antriebseinheit zusammenwirken und diese entsprechend einem zuvor festgelegten Programm ansteuern.The processing of the detected operating states, which is also accompanied by the activation of the drive unit driving the setting unit, can in principle be carried out at any point, for example by separate control devices. According to a particularly advantageous embodiment of the invention, however, the control unit controls the drive unit as a function of the pivoting angle and / or a pivoting movement of the door console relative to the column console, wherein at a standstill of the door console opposite the column console, the drive unit, the actuator in the direction of the blocking position associated position and displaced in a pivoting of the door bracket relative to the column console in the direction of the release position associated position. Thus, it allows a corresponding embodiment of the control unit to dispense with additional processing or control units. The control unit can interact directly with the drive unit and control it in accordance with a predetermined program.
Wie bereits zuvor dargestellt, kann die durch die Steuerungseinheit gewählte Ansteuerung der Antriebseinheit durch geeignete Regelungsprogramme festgelegt werden, in der den einzelnen Betriebzuständen den Kundenwünschen entsprechende Zustände der Antriebseinheit zugeordnet sind. Nach einer Weiterbildung der Erfindung ist dabei vorgesehen, dass die Steuerungseinheit die Antriebseinheit derart steuert, dass das Stellelement in einem Schwenkwinkelbereich um die Schließlage der Fahrzeugtür, insbesondere im Schwenkwinkelbereich von bis zu 25°, besonders bevorzugt bis zu 15°, ausgehend von der Schließlage, in Richtung auf die der Freigabeposition zugeordnete Stellung verstellt ist. Diese Ausgestaltung der Erfindung erlaubt es, die Tür in jedem Fall in besonders einfacher und komfortabler Weise zu schließen bzw. zu öffnen, nachdem im Bereich um die Schließlage der Tür durch das Arretierungselement bevorzugt keine Hemmung der Bewegung durch das Arretierungselement erfolgt. Insbesondere beim Öffnen der Tür erlaubt diese Ausgestaltung der Erfindung die Erfassung einer Schwenkbewegung, so dass es nicht zu einem vorzeitigen Blockieren der Schwenkbewegung durch Aktivierung der Stelleinheit kommt. Auch ein Schließen der Tür lässt sich in einfacher Weise ohne erhöhten Kraftaufwand durchführen, nachdem die Tür im Bereich um die Schließlage unbelastet durch das Arretierungselement verschwenkbar ist.As already described above, the activation of the drive unit selected by the control unit can be defined by suitable control programs in which the individual operating states are assigned to states of the drive unit that correspond to the customer's wishes. According to a development of the invention, it is provided that the control unit controls the drive unit in such a way that the actuating element is in a swivel angle range around the closed position of the vehicle door, in particular in the swivel angle range of up to 25 °, particularly preferably up to 15 °, starting from the closed position. is adjusted in the direction of the release position associated position. This embodiment of the invention makes it possible to close or open the door in any case in a particularly simple and comfortable manner, after in the area around the closed position of the door by the locking preferably no inhibition of movement by the locking element. In particular, when opening the door, this embodiment of the invention allows the detection of a pivoting movement, so that there is no premature blocking of the pivoting movement by activation of the actuating unit. Also a closing The door can be performed in a simple manner without increased effort, after the door in the area around the closed position is unloaded by the locking element pivotable.
Nach einer weiteren Ausgestaltung der Erfindung ist ferner vorgesehen, dass die Steuerungseinheit die Antriebseinheit derart steuert, dass das Stellelement im Schwenkwinkelbereich um die maximale Öffnungslage der Tür, insbesondere im Schwenkwinkelbereich von bis zu 10°, bevorzugt bis zu 5° vor der maximalen Öffnungslage, in Richtung auf die der Blockierlage zugeordnete Stellung verlagert. Bei einer entsprechenden Ausgestaltung des Kraftfahrzeugtürscharniers wird durch die Aktivierung des Stellelements und einer Verlagerung des Arretierungselements in Richtung auf die Blockierlage das Betätigungsmoment im angegebenen Winkelbereich erhöht. Die Tür ist dadurch gegen eine Verlagerung der Tür mit erhöhter Geschwindigkeit in den Endanschlag geschützt. Gemäß dieser Ausgestaltung der Erfindung fungiert die Feststelleinheit als Endlagendämpfer, wobei die Steuerungseinheit derart ausgebildet sein kann, dass sie mit abnehmendem Abstand der Tür vom Endanschlag das Stellelement zunehmend in Richtung auf die Blockierlage verstellt.According to a further embodiment of the invention it is further provided that the control unit controls the drive unit such that the actuator in the swivel angle range to the maximum opening position of the door, in particular in the swivel angle range of up to 10 °, preferably up to 5 ° before the maximum opening position, in Direction shifted to the blocking position assigned position. In a corresponding embodiment of the motor vehicle door hinge, the actuating torque is increased in the specified angular range by the activation of the actuating element and a displacement of the locking element in the direction of the blocking position. The door is thereby protected against displacement of the door at increased speed in the end stop. According to this embodiment of the invention, the locking unit acts as an end stop damper, wherein the control unit can be designed such that it increasingly adjusted with decreasing distance of the door from the end stop the actuating element in the direction of the blocking position.
Nach der Erfindung ist das Arretierungselement durch eine koaxial zum Scharnierstift angeordnete Umschlingungsklammer mit einem sich in Längsachsenrichtung des Scharnierstifts erstreckenden Schlitz gebildet, wobei die Öffnungsweite des Schlitzes zur Verstellung der Umschlingungsklammer zwischen der Freigabeposition und der Blockierlage durch die Stelleinheit einstellbar ist. Die Umschlingungsklammer umgreift den Scharnierstift in einem vorbestimmten Abschnitt des Scharnierstifts. Durch die mit einem Schlitz versehene Ausgestaltung der Umschlingungsklammer lässt sich der Radius der Klammer durch Verkleinerung bzw. Vergrößerung des Schlitzes gegenüber dem Scharnierstift verstellen, wobei mit zunehmender Verringerung der Schlitzbreite eine erhöhte Anpressung der Umschlingungsklammer an den Scharnierstiftabschnitt erreicht wird, bis sich die Umschlingungsklammer in der Blockierlage befindet, in der eine Verschwenkbewegung der Türkonsole gegenüber der Säulenkonsole aufgrund der zwischen der Umschlingungsklammer und dem Scharnierstift bestehenden Reibung vollständig gehemmt ist.According to the invention, the locking element is formed by a coaxial with the hinge pin arranged Umschlingungsklammer with a longitudinal axis of the hinge pin extending slot, wherein the opening width of the slot for adjusting the looping between the release position and the blocking position is adjustable by the actuator. The wrap clamp engages the hinge pin in a predetermined portion of the hinge pin. Through the slot provided Design of the wrap the radius of the clip can be adjusted by reducing or enlarging the slot relative to the hinge pin, with increasing reduction of the slot width increased contact pressure of the wrap is achieved at the hinge pin section until the wrap is in the blocking position in which a Swiveling movement of the door bracket relative to the column console is completely inhibited due to the existing between the belt and the hinge pin friction.
Eine Vergrößerung der Öffnungsweite des Schlitzes hingegen führt zu einer Reduzierung des Anpressdrucks der Umschlingungsklammer auf den Scharnierstift, so dass das zur Verschwenkung der Türkonsole gegenüber der Säulenkonsole erforderliche Betätigungsmoment mit zunehmender Öffnungsweite reduziert wird, bis in der Freigabeposition zwischen dem Scharnierstift und der Umschlingungsklammer im Wesentlichen keine Reibung mehr vorherrscht, so dass das Arretierungselement dann keinen Einfluss auf die Verschwenkbewegung ausübt.An enlargement of the opening width of the slot, however, leads to a reduction of the contact pressure of the belt clip on the hinge pin, so that the required for pivoting the door bracket relative to the column console actuating torque is reduced with increasing opening width, to the release position between the hinge pin and the looping substantially no Friction prevails more, so that the locking element then exerts no influence on the pivoting movement.
Über den Umschlingungswinkel, aus dem sich auch die Öffnungsweite des Schlitzes ergibt, lässt sich - in Abhängigkeit von der Verstellung des Arretierungselements - die zu erreichende Reibung besonders einfach und kostengünstig festlegen, so dass sich das gemäß der vorstehenden Weiterbildung ausgestaltete Kraftfahrzeugtürscharnier besonders kostengünstig herstellen lässt. Darüber hinaus lässt sich auch über die Materialwahl sowie die Oberflächengüte und der sich daraus ergebenden Reibpaarung zwischen dem Scharnierstift und der Umschlingungsklammer eine einfache Festlegung des Betätigungselements erreichen.Depending on the adjustment of the locking element, the friction to be achieved can be defined in a particularly simple and cost-effective manner via the wrap angle, which also results in the opening width of the slot, so that the motor vehicle door hinge designed according to the above development can be produced particularly cost-effectively. In addition, a simple determination of the actuating element can also be achieved via the choice of material and the surface quality and the resulting friction pairing between the hinge pin and the looping clip.
Die Ausgestaltung der Umschlingungsklammer ist - wie bereits vorstehend dargestellt - grundsätzlich frei wählbar, wobei über den Umschlingungswinkel sowie über dessen Länge die zur Reibung mit dem Scharnierstift vorgesehene Fläche einstellbar ist. Die Umschlingungsklammer weist einen an dem Scharnierstift angeordneten Klemmabschnitt sowie zwei sich derart an gegenüberliegende Bereiche des Schlitzes an den Klemmabschnitt anschließende Klemmschenkel auf, dass eine Veränderung des Abstands der einander zugewandten Innenseiten der Klemmschenkel eine Veränderung der Öffnungsweite bewirkt.The embodiment of the looping clip is basically freely selectable, as already explained above, wherein the surface provided for friction with the hinge pin can be adjusted via the looping angle and along its length. The wrap-around bracket has one on the Hinge pin arranged clamping portion and two such adjoining areas of the slot on the clamping portion subsequent clamping leg, that a change in the distance of the facing inner sides of the clamping legs causes a change in the opening width.
Die sich an den koaxial zum Scharnierstift angeordneten Klemmabschnitt anschließenden Klemmschenkel, welche sich im Wesentlichen radial zu diesem erstrecken, ermöglichen es im Falle einer im Abstand vom Scharnierstift angreifenden Stelleinheit und der sich dann ergebenden Hebelwirkung, die Öffnungsweite des Schlitzes mit einem reduzierten Kraftaufwand durch Verstellung des Abstands der Klemmschenkel zueinander zu verändern.The adjoining the coaxial with the hinge pin clamping portion adjoining clamping leg, which extend substantially radially to this, allow it in the case of an attacking at a distance from the hinge pin actuator and then resulting leverage, the opening width of the slot with a reduced effort by adjusting the Distance of the clamping legs to each other to change.
Eine Stelleinheit lässt sich somit verwenden, welche zur Betätigung des Arretierungselements nur einen geringeren Kraftaufwand benötigt, als dies bei einer unmittelbaren Anbindung im Bereich des Scharnierstifts der Fall ist. Der das Betätigungsmoment festlegende Durchmesser des Klemmabschnitts der Umschlingungsklammer wird durch die Veränderung des Abstands der Klemmschenkel zueinander bestimmt, wobei mit zunehmendem Abstand vom Klemmabschnitt bereits geringe Veränderungen des Abstands der Klemmschenkel zueinander eine deutliche Veränderung des Betätigungsmoments zur Folge haben.An actuating unit can thus be used, which only requires a smaller amount of force to actuate the locking element than is the case with an immediate connection in the region of the hinge pin. The operating torque defining diameter of the clamping portion of the looping clamp is determined by the change in the distance of the clamping legs to each other, with increasing distance from the clamping portion even small changes in the distance of the clamping legs to each other have a significant change in the operating torque result.
Vorteilhaft für die Funktion des erfindungsgemäßen Kraftfahrzeugtürscharniers ist es, dass das Arretierungselement ortsfest an der Konsole angeordnet ist, die gegenüber dem Scharnierstift verstellbar ist. Sofern also gemäß einer bevorzugten Ausführungsform des Kraftfahrzeugtürscharniers der Scharnierstift verdrehfest mit der Säulenkonsole verbunden ist, ist das Arretierungselement verdrehfest an der Türkonsole angeordnet, so dass eine Verschwenkbewegung der Türkonsole unmittelbar eine Verstellbewegung des Arretierungselements gegenüber dem Scharnierstift zur Folge hat, die über die Reibung mit dem Scharnierstift das zur Verschwenkung der Tür erforderliche Betätigungsmoment bestimmt.It is advantageous for the function of the motor vehicle door hinge according to the invention that the locking element is fixedly arranged on the console, which is adjustable relative to the hinge pin. Thus, if according to a preferred embodiment of the motor vehicle door hinge, the hinge pin is rotationally connected to the column console, the locking element is rotationally arranged on the door bracket, so that a pivoting movement of the door bracket directly an adjustment of the locking member relative to the hinge pin has the consequence over the friction with the Hinge pin determines the required to pivot the door actuating torque.
Die entsprechende Anordnung des Arretierungselements, welches als Umschlingungsklammer ausgebildet ist, ist grundsätzlich frei wählbar. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist bei der Ausgestaltung des Arretierungselements als Umschlingungsklammer jedoch der erste Klemmschenkel mit seiner Außenseite mit der Stelleinheit und der zweite Klemmschenkel mit seiner Außenseite mit einer Innenwand eines Gehäuses der Feststellereinheit in Eingriff befindlich.The corresponding arrangement of the locking element, which is designed as a wrap-around, is basically arbitrary. According to a particularly advantageous embodiment of the invention, however, in the embodiment of the locking element as a loop clamp, the first clamping leg with its outer side with the setting unit and the second clamping leg with its outer side with an inner wall a housing of the arrester unit is engaged.
Gemäß dieser Ausgestaltung der Erfindung stützt sich die Umschlingungsklammer mit den Außenseiten der beiden Klemmschenkel an der Innenwand des Gehäuses bzw. an der Stelleinheit ab, welche ihrerseits mit der gegenüber dem Scharnierstift gelenkig verbundenen Konsole, bevorzugt der Türkonsole, verbunden ist. Eine Verdrehung der Umschlingungsklammer ist durch diese Ausgestaltung der Erfindung ausgeschlossen, nachdem der zweite Klemmschenkel in seiner Position durch die Innenwand und der erste Klemmschenkel über die Stelleinheit festgelegt ist. Die Stelleinheit ermöglicht es, den ersten Klemmschenkel gegenüber dem zweiten Klemmschenkel zu verstellen, wodurch in Abhängigkeit von der sich dabei einstellenden Öffnungsweite der Umschlingungsklammer das zur Betätigung erforderliche Moment festgelegt wird. Eine weitergehende und komplizierte sowie kostensteigernde Befestigung der Umschlingungsklammer ist gemäß dieser Weiterbildung der Erfindung nicht erforderlich, welche sich darüber hinaus in einfacher Weise montieren lässt.According to this embodiment of the invention, the looping clip is supported by the outer sides of the two clamping legs on the inner wall of the housing or on the setting unit, which in turn is connected to the bracket pivotally connected to the hinge pin, preferably the door bracket. A rotation of the wrap is excluded by this embodiment of the invention, after the second clamping leg is fixed in its position by the inner wall and the first clamping leg on the setting unit. The adjusting unit makes it possible to adjust the first clamping leg relative to the second clamping leg, whereby, depending on the thereby adjusting opening width of the looping clamp, the moment required for actuation is determined. A further and complicated and cost-increasing attachment of the looping clip is not required according to this embodiment of the invention, which can also be mounted in a simple manner beyond.
Wie bereits zuvor dargestellt, erfolgt bei der Ausgestaltung des Arretierungselements als Umschlingungsklammer mit zwei Klemmschenkeln, von denen der erste mit seiner Außenseite mit der Stelleinheit und der zweite mit seiner Außenseite an einer Innenwand eines Gehäuses anliegt, eine Festlegung des Betätigungsmoments über die Stelleinheit, durch die der Abstand zwischen dem ersten und zweiten Klemmschenkel festgelegt wird. Somit sind den einzelnen Positionen der Stelleinheit eindeutige Positionen der Klemmschenkel zueinander zugeordnet.As already shown, takes place in the embodiment of the locking element as wrap loop with two clamping legs, of which the first rests with its outer side with the actuator and the second with its outer side on an inner wall of a housing, a determination of the actuating torque on the setting unit, through the the distance between the first and second clamping legs is determined. Thus, the individual positions of the actuator unit unique positions of the clamping legs are assigned to each other.
Um bei gleichbleibender Stelleinheit die Möglichkeit zur Veränderung des Betätigungsmoments bzw. dessen Verlauf zu erreichen, ist nach einer besonders vorteilhaften Ausgestaltung der Erfindung vorgesehen, dass die Außenseite des zweiten Klemmschenkels an einer in das Gehäuse einschraubbaren und von der Innenwand des Gehäuses vorstehenden Stellschraube anliegt. Gemäß dieser Ausgestaltung der Erfindung liegt die Außenseite des zweiten Klemmschenkels nicht unmittelbar an einer Gehäuseinnenwand an, sondern stützt sich an einer in das Gehäuse hineinragenden Stellschraube ab. Über die Einschraubtiefe der Stellschraube lässt sich somit der Abstand der Außenseite des zweiten Klemmschenkels von der Innenwand des Gehäuses bestimmen, so dass identischen Positionen der Stelleinheit verschiedene Öffnungsweiten des Schlitzes zwischen den Klemmschenkeln zugeordnet werden können.In order to achieve the possibility of changing the actuating torque or its course at the same setting unit, according to a particularly advantageous embodiment of the invention provides that the outside of the second clamping leg rests against a screwed into the housing and protruding from the inner wall of the housing adjusting screw. According to this embodiment of the invention, the outer side of the second clamping leg is not directly adjacent to a housing inner wall, but is supported on a projecting into the housing from adjusting screw. The distance of the outer side of the second clamping leg from the inner wall of the housing can thus be determined via the screw-in depth of the adjusting screw, so that identical positions of the actuating unit are assigned different opening widths of the slot between the clamping legs can.
Somit ermöglicht diese Ausgestaltung der Erfindung die Festlegung unterschiedlicher Betätigungsmomentverläufe bei ansonsten identischem Aufbau des Kraftfahrzeugtürscharniers. Ferner bietet die Verwendung einer Stellschraube die Möglichkeit, den Betätigungsmomentverlauf nachträglich zu korrigieren, an geänderte Anforderungen anzupassen oder speziellen Kundenanforderungen gerecht zu werden. Die Stellschraube ist dabei vorzugsweise von einer Außenseite des Gehäuses zugänglich, so dass eine komfortable Einstellbarkeit gegeben ist.Thus, this embodiment of the invention allows the determination of different operating torque curves with otherwise identical construction of the motor vehicle door hinge. Furthermore, the use of a screw provides the ability to subsequently correct the moment of actuation torque, to adapt to changing requirements or to meet special customer requirements. The adjusting screw is preferably accessible from an outer side of the housing, so that a comfortable adjustability is given.
Die Ausgestaltung der Stelleinheit derart, dass diese mit dem Arretierungselement zusammenwirkt, bevorzugt den ersten Klemmschenkel in Richtung auf den zweiten Klemmschenkel in Abstand verstellen kann, ist ebenfalls grundsätzlich frei wählbar. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung liegt die Außenseite des ersten Klemmschenkels jedoch an einer im Abstand gegenüber dem zweiten Klemmschenkel veränderlichen Kontaktfläche des Stellelements der Verstelleinheit an.The configuration of the setting unit such that it cooperates with the locking element, preferably the first clamping leg in the direction of the second clamping leg can be adjusted in distance, is also basically freely selectable. According to a particularly advantageous embodiment of the invention, however, the outer side of the first clamping leg bears against a variable contact surface of the adjusting element of the adjusting unit that is variable with respect to the second clamping leg.
Gemäß dieser Ausgestaltung der Erfindung besteht im Bereich zwischen der Freigabeposition und der Blockierlage eine dauerhafte Anlage einer Kontaktfläche des Stellelements an der Außenseite des ersten Klemmschenkels. Der Abstand der an der Außenseite des ersten Klemmschenkels anliegenden Kontaktfläche gegenüber dem zweiten Klemmschenkel ist dabei über eine Betätigung der Stelleinheit veränderbar, wodurch sich zwangsläufig auch eine Änderung des Abstands der beiden Klemmschenkel zueinander ergibt, wobei bevorzugt die durch das Stellelement erzielte Verlagerung der Klemmschenkel zueinander im elastischen Bereich der Umschlingungsklammer erfolgt, so dass ohne weitergehende Hilfsmittel eine dauerhafte Anlage der Kontaktfläche an der Außenseite des ersten Klemmschenkels gewährleistet ist.According to this embodiment of the invention is in the area between the release position and the blocking position a permanent contact surface of a contact surface of the actuating element on the outside of the first clamping leg. The distance between the voltage applied to the outside of the first clamping leg contact surface relative to the second clamping leg is modifiable via actuation of the adjusting unit, which inevitably results in a change in the distance between the two clamping legs to each other, preferably achieved by the adjusting element displacement of the clamping legs to each other in elastic region of the looping takes place, so that without further aids a permanent contact surface is ensured on the outside of the first clamping leg.
Besonders bevorzugt weist dabei die Außenseite des ersten Klemmschenkels einen an der Kontaktfläche anliegenden Steg auf, wodurch sich eine besonders zuverlässige Verstellung des ersten Klemmschenkels gegenüber dem zweiten Klemmschenkel realisieren lässt. Der Steg kann dabei einstückig mit dem ersten Klemmschenkel ausgebildet, aber auch durch ein mit dem ersten Klemmschenkel verbundenes Bauteil gebildet sein, wobei der Steg auch durch vom Material der Umschlingungsklammer abweichenden Materialien gebildet sein kann, welche an die Reibbelastung angepasst sind.In this case, the outside of the first clamping leg particularly preferably has a web resting against the contact surface, as a result of which a particularly reliable adjustment of the first clamping leg relative to the second clamping leg can be realized. The web can be formed integrally with the first clamping leg, but also be formed by a connected to the first clamping leg component, wherein the web also may be formed by deviating from the material of the belt clip materials, which are adapted to the friction load.
Erfindungsgemäß ist das Stellelement durch einen auf einer Nockenwelle angeordneten Exzenternocken gebildet, der derart ausgebildet ist, dass eine Verdrehung der vorzugsweise parallel zum Scharnierstift verlaufenden Nockenwelle eine Veränderung des Abstands der Kontaktfläche des Exzenternockens zum zweiten Klemmschenkel bewirkt.According to the invention, the adjusting element is formed by a camshaft arranged on an eccentric cam, which is designed such that a rotation of the preferably parallel to the hinge pin extending camshaft causes a change in the distance of the contact surface of the eccentric cam to the second clamping leg.
Der Exzenternocken, welcher sich besonders vorteilhafterweise in axialer Richtung des Scharnierstifts weitestgehend über die Länge des ersten Klemmschenkels erstreckt, weist eine Kontaktfläche auf, deren Abstand zur Nockenwelle sich in Umfangsrichtung verändert, um eine Verstellung des ersten Klemmschenkels in Abhängigkeit der Verdrehung der Nockenwelle zu erreichen. Durch diese Ausgestaltung der Erfindung lässt sich durch eine einfache Verdrehung der den Exzenternocken tragenden Nockenwelle der Abstand zwischen dem ersten und zweiten Klemmschenkel festlegen. Die Ausgestaltung des Exzenternockens bestimmt dabei in Abhängigkeit von dem Drehwinkel der Nockenwelle das festgelegte Betätigungsmoment, wobei die Kontur der Kontaktfläche des Exzenternockens ferner den Verlauf des Betätigungsmoments zwischen der Blockierlage und der Freigabeposition festgelegt.The eccentric cam, which extends particularly advantageously in the axial direction of the hinge pin as far as possible over the length of the first clamping leg, has a contact surface whose distance from the camshaft changes in the circumferential direction to achieve an adjustment of the first clamping leg in dependence of the rotation of the camshaft. By means of this embodiment of the invention, the distance between the first and second clamping legs can be determined by a simple rotation of the camshaft carrying the eccentric cam. The configuration of the eccentric cam determines depending on the angle of rotation of the camshaft, the specified operating torque, wherein the contour of the contact surface of the eccentric cam further defines the course of the actuating torque between the blocking position and the release position.

Die Türkonsole 2 hingegen ist gegenüber dem Scharnierstift 3 gelenkig angeordnet. Die gelenkige Anbindung erfolgt dabei über eine drehgelenkige Lagerung des Scharnierstifts 3 an einer Gehäusebodenbuchse 14 sowie einer Gehäusedeckelbuchse 18 eines verdrehfest mit der Türkonsole 2 verbundenen Gehäuses 6 einer Feststelleinheit 4. Die Gehäusebodenbuchse 14 sowie die Gehäusedeckelbuchse 18 sind dabei am Gehäuseboden 11 bzw. Gehäusedeckel 10 ausgebildet, die dazu dienen das Gehäuse 6 in axialer Richtung des Scharnierstifts 3 zu schließen.The
Aufgrund der gelenkigen Aufnahme des Scharnierstifts 3 in den Lagerbuchsen 14, 18 kann die Türkonsole 2 gegenüber dem Scharnierstift 3 verschwenkt werden, wobei die Feststelleinheit 4 relativ gegenüber dem Scharnierstift 3 mitverschwenkt wird. Die Schwenkbewegung der Türkonsole 2 gegenüber der Säulenkonsole 1 in Öffnungsrichtung ist dabei über einen Endanschlag begrenzt, der durch einen an das Gehäuse 6 angesetzten Ausleger 8 sowie einen an der Säulenkonsole 1 angeordneten Anschlag 7 gebildet wird, die in der maximalen Öffnungsposition aneinander anliegen. Um dabei eine grundsätzlich gute Verschwenkbarkeit der Türkonsole 2 gegenüber der Säulenkonsole 1 zu gewährleisten, ist zwischen der Gehäusebodenbuchse 14 und einem die Einstecktiefe des Scharnierstifts 3 in die Aufnahmeöffnung an dem Ausleger 5 begrenzenden Flansch 12 eine Gleitscheibe 13 angeordnet.Due to the articulated receiving the
Innerhalb des Gehäuses 6 der Feststelleinheit 4 ist eine als Arretierungselement ausgebildete Umschlingungsklammer 17 mit einem Klemmabschnitt 21 koaxial zum Scharnierstift 3 angeordnet, wobei der Klemmabschnitt 21 den Scharnierstift 3 jedoch nicht vollständig umgreift. Daher weist der Klemmabschnitt 21 einen sich in axialer Richtung des Scharnierstifts 3 erstreckenden Schlitz auf, dessen Öffnungsweite sich durch den Abstand zweier sich im Bereich des Schlitzes an den Klemmabschnitt 21 anschließender Klemmschenkel 22, 23 variieren lässt. Durch die Festlegung des Abstands der Klemmschenkel 22, 23 zueinander lässt sich die Andruckkraft festlegen, mit der der Klemmabschnitt 21 der Umschlingungsklammer 17 auf den Scharnierstift 3 wirkt.Within the
Zur Einstellung des Abstands der Klemmschenkel 22, 23 zueinander ist zunächst vorgesehen, dass der zweite Klemmschenkel 23 mit seiner Außenseite gegenüber dem Gehäuse 6 abgestützt ist. Die Abstützung erfolgt dabei an einer in das Gehäuse 6 einschraubbaren Stellschraube 16, welche von der Innenseite des Gehäuses 6 vorsteht, so dass die Außenseite des zweiten Klemmschenkels 23 an der Stellschraube 16 anliegt. Nachdem der zweite Klemmschenkel 23 somit gegenüber dem ersten Klemmschenkel 22 nicht ausweichen kann, kann eine Veränderung der Schlitzbreite durch eine Veränderung des Abstandes der Klemmschenkel 22, 23 dadurch erfolgen, dass der erste Klemmschenkel 22 relativ gegenüber dem zweiten Klemmschenkel 23 verstellt wird.To set the distance of the clamping
Zur Verstellung des ersten Klemmschenkels 22 dient eine Stelleinheit 29, die ein als Exzenternocken 15 ausgebildetes Stellelement 15 aufweist, welcher auf einer drehbar gegenüber dem Gehäuse 6 gelagerten Nockenwelle 9 angeordnet ist. Die Lagerung der Nockenwelle 9 erfolgt dabei über Lagerbuchsen 34, die in geeigneten Öffnungen im Gehäuseboden 11 und im Gehäusedeckel 10 angeordnet sind. Der Exzenternocken 15 liegt mit einer Kontaktfläche 36 an einem an der Außenseite des ersten Klemmschenkels 22 angeordneten Steg 35 an. Nachdem sich durch eine Verdrehung des Exzenternockens 15 der Abstand der Kontaktfläche 36 - die in Umfangsrichtung aufgrund ihrer Kontur einen variierenden Abstand zur Nockenwelle 9 aufweist - gegenüber dem zweiten Klemmschenkel 23 ändert, resultiert aus einer Verdrehung der Nockenwelle 9 eine Verlagerung des ersten Klemmschenkels 22 gegenüber dem zweiten Klemmschenkel 23. Hierdurch verändert sich der Abstand der Klemmschenkel 22, 23 zueinander, so dass die durch den Klemmabschnitt 21 auf den Scharnierstift 3 wirkende Klemmkraft einstellbar ist.To adjust the
Zur Verstellung des Exzenternockens 15 der Stelleinheit 29 ist auf dem Ende der Nockenwelle 9, welches durch den Gehäusedeckel 10 aus dem Gehäuse 6 hinausragt, eine Nockenwellenscheibe 25 angeordnet, welche in Wirkverbindung mit einer Abtriebswelle 31 eines Elektromotors 28 steht.To adjust the
Der Elektromotor 28 ist Bestandteil einer Steuerungseinheit 27, die darüber hinaus einen Signalaufnehmer 30 aufweist. Die Steuerungseinheit 27 weist ein Steuerungseinheitsgehäuse 32 auf, welches an dem Gehäuse 6 der Feststelleinheit 4 befestigt ist. Der Signalaufnehmer 30 befindet sich dabei in Wirkverbindung mit einem auf dem Ende des Scharnierstifts 3 angeordneten Signalgeber 26 und ermöglicht die Erfassung des Schwenkwinkels der Türkonsole 2 gegenüber der Säulenkonsole 1 sowie der Ermittlung einer erfolgenden Schwenkbewegung.The
