Eine Türgriffanordnung der eingangs bezeichneten Art ist zum Beispiel aus der
Türaußengriffe weisen als Teil der gesamten Türgriffanordnung Handhaben auf, die von einem Benutzer umgriffen oder hintergriffen werden können. So kann der Benutzer Kraft auf die Handhabe ausüben, um die Tür zu öffnen oder zu schließen oder diese über ihren Schwenkbereich zu bewegen. Fahrzeugtürgriffe sind mit Kopplungsmitteln versehen, die eine Montage des Fahrzeugtürgriffes an der Fahrzeugtür ermöglichen.Exterior door handles have handles as part of the overall door handle assembly which can be gripped or gripped behind by a user. This allows the user to apply force to the handle to open or close the door close or move them over their swivel range. Vehicle door handles are provided with coupling means which allow the vehicle door handle to be mounted on the vehicle door.
Derartige Fahrzeugtürgriffe sind in unterschiedlichen Gestaltungen bekannt und verfügbar. So sind Türgriffanordnungen mit bewegbarer Handhabe als auch Türgriffanordnungen mit einer sogenannten feststehenden Handhabe bekannt. Während bei bewegbaren Handhaben ein vom Benutzer zu untergreifender oder hintergreifender Handhabeteil der Fahrzeugtürgriffanordnung durch Krafteinwirkung geschwenkt oder translatorisch bewegt wird, ist die Handhabe bei feststehenden Türgriffen nicht schwenkbar oder translatorisch bewegbar. Bei Fahrzeugtürgriffen mit feststehender Handhabe ist die Handhabe gegenüber der Tür weitgehend unbeweglich. Bei Türgriffen mit feststehenden Handhaben wird mangels eines mechanischen Verstellweges keine durchgehende mechanische Wirkungskette vom Türgriff auf ein Türschloss ausgebildet. Stattdessen wird das Türschloss in Abhängigkeit von einer detektierten Betätigung elektrisch angesteuert, so dass die mechanische Hardware reduziert werden kann und Kosten und Gewicht bei der Türgriffanordnung eingespart werden können.Such vehicle door handles are known and available in different designs. Thus, door handle assemblies with a movable handle and door handle assemblies with a so-called fixed handle known. While in movable handle a user to be taken under or engaging behind handle part of the vehicle door handle assembly is pivoted or translationally moved by force, the handle is not pivotable or translationally movable with fixed door handles. In vehicle door handles with a fixed handle, the handle against the door is largely immobile. For door handles with fixed handles no continuous mechanical chain of action is formed by the door handle on a door lock for lack of a mechanical adjustment. Instead, the door lock is electrically energized in response to a detected actuation so that the mechanical hardware can be reduced and the cost and weight of the door handle assembly can be saved.
In Kombination mit solchen feststehenden Handhaben und Fahrzeugtürgriffanordnungen kommen elektrisch angesteuerte Türschlösser zum Einsatz. Solche elektrisch angesteuerten Türschlösser sind allgemein unter der Bezeichnung "E-latch" bekannt. Ein Beispiel für ein solches Türsystem ist in der
Auf welche Weise Fahrzeugtürgriffanordnungen mit feststehender Handhabe die Betätigung der Handhabe detektieren, ist im Stand der Technik unterschiedlich gelöst. Am oder im Fahrzeugtürgriff können Schalter oder kapazitive Sensoren verwendet werden. Auch die Verwendung von induktiven Sensoren ist möglich. Im Sinne der Erfindung ist unter der verwendeten Bezeichnung "Sensorelektronik" sowohl ein Schalter, eine Taste, ein kapazitiver Sensor oder ein induktiver Sensor zu verstehen, welche zur Detektion einer durch einen Benutzer bewirkten Betätigung der Handhabe dienen.How vehicle door handle assemblies with a fixed handle detect actuation of the handle has been solved differently in the prior art. Switches or capacitive sensors can be used on or in the vehicle door handle. The use of inductive sensors is possible. For the purposes of the invention, the term "sensor electronics" used is understood to mean both a switch, a button, a capacitive sensor or an inductive sensor, which are used to detect actuation of the handle by a user.
Bei elektrisch ansteuerbaren und öffenbaren Schließsystemen besteht das Problem, dass bei einem Systemausfall oder Stromausfall der Zugang zum Kraftfahrzeug verwehrt bleibt.Electrically controlled and openable locking systems have the problem that in the event of a system failure or power failure, access to the motor vehicle is denied.
Der Erfindung liegt daher die Aufgabe zugrunde eine Lösung zu schaffen, die auf konstruktiv einfache Weise eine Türgriffanordnung bereitstellt, die kostengünstig in ihrer Herstellung und einfach zu montieren ist und bei der darüber hinaus im Fall eines Systemausfalls (zum Beispiel infolge eines Fahrzeugunfalls) oder eines Stromausfalls (zum Beispiel infolge einer schwachen Batterie) dennoch der Zugang zum Inneren des Kraftfahrzeugs ermöglicht wird.The invention is therefore an object of the invention to provide a solution that provides a door handle assembly in a structurally simple manner, which is inexpensive to manufacture and easy to assemble and in addition in case of system failure (for example, as a result of a vehicle accident) or a power failure (For example, due to a weak battery) nevertheless the access to the interior of the motor vehicle is made possible.
Diese Aufgabe wird durch eine Türgriffanordnung eines Kraftfahrzeugs mit den Merkmalen des Patentanspruches 1 gelöst.This object is achieved by a door handle assembly of a motor vehicle having the features of
Wie die gattungsgemäßen und vorstehend beschriebenen Türgriffanordnungen weist auch die erfindungsgemäße Türgriffanordnung einen innenseitig an einer Tür oder Klappe des Kraftfahrzeugs befestigbaren und rahmenartig ausgebildeten Träger, eine außenseitig an der Tür oder Klappe des Kraftfahrzeugs anordenbare Handhabe, die von einem Benutzer hintergreifbar ist, ein Türschloss der Tür oder Klappe des Kraftfahrzeugs, das sowohl mechanisch als auch elektrisch angesteuert und geöffnet werden kann, und eine Sensorelektronik zur Detektion einer durch einen Benutzer bewirkten Betätigung der Handhabe auf. Dabei ist ein erstes Längsende der Handhabe schwenkbar an dem Träger gelagert und ein zweites Längsende der Handhabe ist auslenkbar von dem Träger weg mit dem Träger gekoppelt.Like the generic door handle arrangements described above, the door handle arrangement according to the invention also has a carrier which can be fastened on the inside to a door or flap of the motor vehicle and has a handle which can be arranged on the outside of the door or flap of the motor vehicle, which can be grasped by a user, a door lock of the door or flap of the motor vehicle, which can be controlled and opened both mechanically and electrically, and a sensor electronics for detecting an actuation of the handle caused by a user. In this case, a first longitudinal end of the handle is pivotally mounted on the carrier and a second longitudinal end of the handle is deflectably coupled away from the carrier with the carrier.
Ein mechanisches und am Träger festgelegtes Rückhalteelement übt auf das zweite Längsende der Handhabe eine vorbestimmte Rückhaltekraft in Richtung des Trägers aus, so dass das Rückhalteelement die Handhabe in einer unausgelenkten Normalbetätigungsposition hält. In der Normalbetätigungsposition kann ein Benutzer die Handhabe betätigen, ohne dass dabei die Handhabe ausgelenkt wird. Dabei öffnet die Sensorelektronik bei Detektion einer Betätigung der Handhabe durch einen Benutzer mit einer von dem Träger weg gerichteten Normalbetätigungskraft, die kleiner als die vorbestimmte Rückstellkraft ist, die Tür oder Klappe elektrisch. Dadurch, dass die Normalbetätigungskraft, die kleiner als die vorbestimmte Rückstellkraft ist, verbleibt die Handhabe in ihrer Normalbetätigungsposition angeordnet. Die Handhabe wird also bei normaler Betätigung durch einen Benutzer nicht ausgelenkt, weil die übliche Normalbetätigungskraft kleiner als die Rückstellkraft des Rückhalteelements ist. Die Handhabe erweckt dabei für den Benutzer den Anschein einer feststehenden Handhabe, was durch die vorliegende Erfindung erwünscht ist.A mechanical retention member secured to the carrier exerts a predetermined restraining force toward the wearer on the second longitudinal end of the handle such that the retention member holds the handle in an undeflected normal operating position. In the normal operating position, a user can operate the handle, without causing the handle is deflected. In this case, the sensor electronics opens upon detection of actuation of the handle by a user with a directed away from the carrier normal actuating force, which is smaller than the predetermined restoring force, the door or Flap electrically. Characterized in that the normal operating force, which is smaller than the predetermined restoring force, the handle remains disposed in its normal operating position. The handle is therefore not deflected during normal operation by a user, because the usual normal operating force is smaller than the restoring force of the retaining element. The handle thereby gives the user the appearance of a fixed handle, which is desired by the present invention.
Kommt es zu einem Notfall, entweder infolge eines Systemausfalls oder eines Stromausfalls, so besteht bei der erfindungsgemäßen Türgriffanordnung die Möglichkeit einer Notöffnung. Dies wird dadurch ermöglicht, weil die Handhabe bei einer Betätigung der Handhabe mit einer von dem Träger weg gerichteten Notbetätigungskraft, die größer als die vorbestimmte Rückstellkraft ist, in eine Notbetätigungsposition auslenkbar ist, in welcher die Auslenkbewegung der Handhabe die Tür oder Klappe mechanisch öffnet. Es versteht sich von selbst, dass die Notbetätigungskraft deutlich größer sein muss als die Normalbetätigungskraft, so dass ein Benutzer wirklich nur in einem Notfall mit entsprechend großer Kraft auf die Handhabe einwirkt und an ihr zieht. Die erfindungsgemäße Türgriffanordnung ist somit weder der Gruppe der Türgriffanordnungen mit bewegbarer Handhabe noch der Gruppe der Türgriffanordnungen mit feststehender Handhabe zuzuordnen. Vielmehr verwendet die erfindungsgemäße Türgriffanordnung Aspekte beider Gruppen und zeichnet sich folglich durch eine pseudo-feststehende Handhabe aus, die bei Normalbetätigung feststehend in ihrer Normalbetätigungsposition verbleibt und die nur bei einer Notbetätigung mit einer entsprechend großen Notbetätigungskraft in eine Notbetätigungsposition auslenkbar ist, in der die Tür bzw. das Türschloss mechanisch geöffnet wird.If there is an emergency, either as a result of a system failure or a power failure, there is the possibility of emergency opening in the door handle assembly according to the invention. This is made possible because the handle upon actuation of the handle with a directed away from the carrier Notbetätigungskraft greater than the predetermined restoring force is deflected into an emergency operating position in which the deflection movement of the handle mechanically opens the door or flap. It goes without saying that the Notbetätigungskraft must be much greater than the normal actuation force, so that a user really only in an emergency with a correspondingly large force acts on the handle and pulls on her. The door handle assembly according to the invention is thus assigned neither the group of door handle assemblies with a movable handle nor the group of door handle assemblies with a fixed handle. Rather, the door handle assembly according to the invention uses aspects of both groups and is thus characterized by a pseudo-fixed handle, which remains stationary in normal operation in its normal operating position and which is deflected only in an emergency operation with a correspondingly large Notbetätigungskraft in an emergency operating position in which the door or The door lock is mechanically opened.
Die Erfindung sieht vor, dass ein Klammerelement verschiebbar an dem Träger gelagert ist und einen zur mechanischen Entriegelung eines Türschlosses der Tür oder Klappe dienenden Schließzylinder oder eine Schließzylinderattrappe am Träger fixiert, wobei die Handhabe in der unausgelenkten Normalbetätigungsposition eine Abdeckung für den Schließzylinder oder die Schließzylinderattrappe bildet, und wobei das Klammerelement zwischen einer Montageposition, in welcher das Klammerelement mit dem Schließzylinder oder der Schließzylinderattrappe außer Eingriff steht, und einer Betriebsposition, in welcher das Klammerelement den Schließzylinder oder die Schließzylinderattrappe am Träger fixiert, bewegbar ist. Das Klammerelement kann nicht nur allein zur Fixierung des Schließzylinders dienen, sondern gleichzeitig auch bei entsprechender Ausgestaltung als Einbruchschutz zur Sicherung des Schließzylinders. Der Handhabe wird bei dieser Ausgestaltung gleichzeitig als Abdeckung für den Schließzylinder genutzt.The invention provides that a clamp member is slidably mounted on the carrier and serving for the mechanical unlocking of a door lock of the door or flap lock cylinder or a lock cylinder dummy on Carrier fixed, wherein the handle in the undeflected normal operating position forms a cover for the lock cylinder or the lock cylinder dummy, and wherein the clamping element between a mounting position in which the clamp member with the lock cylinder or the lock cylinder dummy disengaged, and an operating position in which the clamping element the lock cylinder or the lock cylinder dummy fixed to the carrier, is movable. The clamp element can not only serve alone to fix the lock cylinder, but at the same time as a burglary protection for securing the lock cylinder with appropriate design. The handle is also used in this embodiment as a cover for the lock cylinder.
Gemäß einer ersten Ausführungsform der erfindungsgemäßen Türgriffanordnung ist es konstruktiv besonders günstig, wenn das mechanische Rückhalteelement ein elastisches Federelement umfasst, das an dem Klammerelement und mit diesem mitbewegbar befestigt ist, wobei sich ein erster Schenkel des elastischen Federelements an einem Stützansatz des Klammerelements oder an einem am Träger angeformten Stützansatz abstützt. Durch die Ausbildung als elastisches Federelement ist die Rückstellkraft sehr genau einstellbar, was sich auf die im Notfall aufzubringende Rückstellkraft positiv auswirkt. Darüber hinaus ist die Verwendung eines elastischen Federelements wirtschaftlich günstig. Im Betrieb der Türgriffanordnung ist es wesentlich, dass sich der erste Schenkel an einem im Hinblick auf die Handhabe ortsfesten Stützansatz abstützt, damit das elastische Federelement entsprechend seiner vorgeschriebenen Wirkungsweise komprimiert werden kann, um seine vorgegebene Kraft entsprechend des Betriebszustandes der Türgriffanordnung zu entfalten. Entsprechend kann der Stützansatz entweder an dem Träger oder an dem im Betrieb ortsfest zum ortsfesten Träger angeordneten Klammerelement ausgebildet sein.According to a first embodiment of the door handle assembly according to the invention, it is structurally particularly advantageous if the mechanical restraint element comprises an elastic spring element, which is attached to the clamp element and mitbewegbar with this, wherein a first leg of the elastic spring element is supported on a support shoulder of the clip member or on a support neck integrally formed on the support. Due to the design as an elastic spring element, the restoring force is very accurately adjustable, which has a positive effect on the restoring force to be applied in an emergency. In addition, the use of an elastic spring element is economically favorable. In operation, the door handle assembly, it is essential that the first leg is supported on a stationary with respect to the handle support projection so that the elastic spring element can be compressed according to its prescribed mode of action to develop its predetermined force corresponding to the operating state of the door handle assembly. Accordingly, the support lug may be formed either on the carrier or on the stationary during operation fixed to the stationary carrier clamp member.
In Ausgestaltung der ersten Ausführungsform sieht die Erfindung vor, dass ein zweiter Schenkel des elastischen Federelements in Montageposition an einem Montageansatz des Klammerelements abstützend angeordnet ist und in Betriebsposition an einem am zweiten Längsende der Handhabe ausgebildeten Rückhalteanschlag angreifend angeordnet ist, wobei in der Betriebsposition das elastische Federelement mit der vorbestimmten Rückstellkraft die Handhabe über den Rückhalteanschlag in ihre Normalbetätigungsposition drängt. Alternativ dazu ist es aber auch möglich, dass ein zweiter Schenkel des elastischen Federelements in Montageposition an dem Träger vorfixiert ist und in Betriebsposition an einem am zweiten Längsende der Handhabe ausgebildeten Rückhalteanschlag angreifend angeordnet ist, wobei in der Betriebsposition das elastische Federelement mit der vorbestimmten Rückstellkraft die Handhabe über den Rückhalteanschlag in ihre Normalbetätigungsposition drängt. Das Rückhalteelement in Form des Federelements wirkt somit auf die Handhabe direkt ein und hält diese auch während einer normalen Betätigung in der Normalbetätigungsposition, so dass der Benutzer das Gefühl hat, er betätigt eine feststehende Handhabe. Für die Montage ist es besonders von Vorteil, dass das Rückhalteelement an dem Klammerelement angeordnet ist und während der Montage mit dem Klammerelement am Träger entlang verschoben wird, wodurch der zweite Schenkel des Federelements in Anlage an das zweite Längsende der Handhabe gelangt und auf das zweite Längsende seine Rückstellkraft aufbringt.In an embodiment of the first embodiment, the invention provides that a second leg of the elastic spring element is arranged supportingly in the mounting position on a mounting projection of the clip element and is arranged attacking in the operating position on a formed on the second longitudinal end of the handle retention stop, wherein in the operating position, the elastic spring element with the predetermined restoring force urges the handle over the retaining stop in its normal operating position. Alternatively, it is also possible that a second leg of the elastic spring element is prefixed in the mounting position on the carrier and is arranged attacking in operating position on a trained on the second longitudinal end of the handle retention stop, wherein in the operating position, the elastic spring element with the predetermined restoring force Move handle over the retaining stop in its normal operating position. The retaining element in the form of the spring element thus acts directly on the handle and holds it during a normal operation in the Normal operating position, so that the user has the feeling that he operates a fixed handle. For mounting, it is particularly advantageous that the retaining element is arranged on the clamp element and is displaced along the support during assembly with the clamp element, whereby the second leg of the spring element comes into contact with the second longitudinal end of the handle and on the second longitudinal end applies its restoring force.
Für eine Notbetätigung bei der ersten Ausführungsform ist es von besonderem Vorteil, wenn das zweite Längsende der Handhabe eine Einrastausnehmung aufweist, in welche der zweite Schenkel des elastischen Federelements bei einer Betätigung der Handhabe mit einer von dem Träger weg gerichteten Notbetätigungskraft derart einrastbar ist, dass die Handhabe in der Notbetätigungsposition gehalten angeordnet ist und ein mechanischer Schlüssel in den Schließzylinder einschiebbar ist. Die Handhabe ist demnach von dem Träger abgehoben angeordnet und erlaubt einen ungehinderten Zugang zu dem Schließzylinder, ohne dass dabei ein Benutzer die Handhabe mit hohem Kraftaufwand in der Notbetätigungsposition halten muss, um zur Entriegelung den Schlüssel in den Schließzylinder einzuführen.For an emergency operation in the first embodiment, it is particularly advantageous if the second longitudinal end of the handle has a Einrastausnehmung, in which the second leg of the elastic spring element during actuation of the handle with a directed away from the carrier Notbetätigungskraft is latched such that the Handle is arranged held in the Notbetätigungsposition and a mechanical key is inserted into the lock cylinder. The handle is thus arranged lifted from the carrier and allows unimpeded access to the lock cylinder, without causing a user to hold the handle with great effort in the Notbetätigungsposition to insert the key to unlock the lock cylinder.
Bei der ersten Ausführungsform ist es schließlich konstruktiv besonders günstig, wenn die Handhabe über einen Bowdenzug mit dem Türschloss mechanisch gekoppelt ist. Durch diese Ausgestaltung wirkt im Notfall die auf die Handhabe aufgebrachte Kraft, die größer als die vorbestimmte Rückstellkraft des Rückhalteelements bzw. des Federelements sein muss, direkt auf das Türschloss.In the first embodiment, it is finally structurally particularly favorable when the handle is mechanically coupled via a Bowden cable with the door lock. As a result of this configuration, the force applied to the handle in an emergency, which must be greater than the predetermined restoring force of the retaining element or the spring element, acts directly on the door lock.
Gemäß einer zweiten Ausführungsform ist vorgesehen, dass die Handhabe über einen am Träger drehbar gelagerten Umlenkhebel und einen mit dem Umlenkhebel verbundenen Bowdenzug mit dem Türschloss mechanisch verbunden ist.According to a second embodiment, it is provided that the handle is mechanically connected to the door lock via a deflecting lever rotatably mounted on the carrier and a Bowden cable connected to the reversing lever.
Dementsprechend ist bei der zweiten Ausführungsform aufgrund des Umlenkhebels eine andere Lagerung des Rückhalteelements vorzusehen. Die Erfindung sieht dementsprechend für die zweite Ausführungsform der Türgriffanordnung vor, dass das mechanische Rückhalteelement ein elastisches Federelement umfasst, das über eine an dem Träger und dem Umlenkhebel gelagerte Federachse zwischen dem Träger und dem Umlenkhebel angeordnet ist, wobei sich ein erstes Federende des Federelements an dem Träger abstützt. Durch die Ausbildung als elastisches Federelement ist die Rückstellkraft sehr genau einstellbar, was sich auf die im Notfall aufzubringende Rückstellkraft positiv auswirkt. Darüber hinaus ist die Verwendung eines elastischen Federelements wirtschaftlich günstig.Accordingly, in the second embodiment, due to the reversing lever to provide a different storage of the retaining element. Accordingly, for the second embodiment of the door handle assembly, the invention provides that the mechanical retaining element comprises an elastic spring element that over a spring axis mounted on the carrier and the deflection lever is arranged between the carrier and the deflection lever, wherein a first spring end of the spring element is supported on the carrier. Due to the design as an elastic spring element, the restoring force is very accurately adjustable, which has a positive effect on the restoring force to be applied in an emergency. In addition, the use of an elastic spring element is economically favorable.
Für die weitere Lagerung des elastischen Federelements sieht die Erfindung gemäß der zweiten Ausführungsform vor, dass sich ein zweites Federende des elastischen Federelements sowohl in Montageposition als auch in Betriebsposition an dem Umlenkhebel abstützt, wobei das Klammerelement bei seiner Bewegung aus der Montageposition in die Betriebsposition den Umlenkhebel in Eingriff mit dem zweiten Längsende der Handhabe bringt. Der Umlenkhebel ist bei der zweiten Ausführungsform folglich mit dem Klammerelement bewegungsgekoppelt, so dass eine Bewegung des Klammerelements aus der Montageposition in die Betriebsposition nicht nur den Schließzylinder am Träger fixiert, sondern auch die Handhabe und den Umlenkhebel in Eingriff bringt.For the further storage of the elastic spring element, the invention according to the second embodiment provides that a second spring end of the elastic spring element is supported both in the mounting position and in the operating position on the reversing lever, wherein the clamping element during its movement from the mounting position to the operating position of the lever brings into engagement with the second longitudinal end of the handle. The bellcrank in the second embodiment is thus rotationally coupled to the clamp member so that movement of the clamp member from the mounting position to the operative position not only secures the lock cylinder to the carrier but also engages the handle and the bell crank.
Entsprechend der andersartigen Lagerung bei der zweiten Ausführungsform sieht die Erfindung in weiterer Ausgestaltung für diese vor, dass in der Betriebsposition das elastische Federelement mit der vorbestimmten Rückstellkraft die Handhabe über den Umlenkhebel in ihre Normalbetätigungsposition drängt, wobei das elastische Federelement dabei den Umlenkhebel mit der Handhabe in Eingriff gedrückt hält. Primär wirkt das zweite Federende derart auf den Umlenkhebel ein, dass dieser in einer Ausgangsposition gehalten ist, in welcher die mit dem Umlenkhebel gekoppelte Handhabe in der Normalbetätigungsposition, also unausgelenkt wie eine feststehende Handhabe, gehalten ist.According to the different storage in the second embodiment, the invention provides in a further embodiment for this, that in the operating position, the elastic spring element with the predetermined restoring force urges the handle on the lever in its normal operating position, wherein the elastic spring element while the lever with the handle in Holds engagement. Primarily, the second spring end acts on the reversing lever in such a way that it is held in a starting position, in which the handle coupled to the reversing lever is held in the normal operating position, ie undeflected, like a fixed handle.
Um im Notfall die Tür entriegeln zu können, sieht die Erfindung bei der zweiten Ausführungsform vor, dass die Handhabe an ihrem zweiten Längsende eine in Flucht zu dem Schließzylinder demontierbar angebrachte Verschlusskappe aufweist, durch welche hindurch bei Demontage der Verschlusskappe ein mechanischer Schlüssel in den Schließzylinder einschiebbar ist.In order to unlock the door in an emergency, the invention provides in the second embodiment, that the handle has at its second longitudinal end a removable in alignment with the lock cylinder cap, through which when disassembling the cap a mechanical key is inserted into the lock cylinder.
Zur Demontage der Verschlusskappe ist es dann von Vorteil, wenn die Handhabe an ihrem zweiten Längsende eine Öffnung aufweist, durch die hindurch ein mechanischer Schlüssel zur Demontage der Verschlusskappe einschiebbar ist.For disassembly of the closure cap, it is advantageous if the handle has at its second longitudinal end an opening through which a mechanical key for disassembly of the closure cap can be inserted.
Sowohl für die erste als auch für die zweite Ausführungsform ist in Ausgestaltung der Erfindung vorgesehen, dass die vorbestimmte Rückstellkraft des mechanischen Rückhalteelements zwischen wenigstens sechzig Newton und höchstens einhundert Newton beträgt. Besonders bevorzugt ist es, wenn die vorbestimmte Rückstellkraft des mechanischen Rückhalteelements fünfundachtzig Newton (85N) beträgt. Daraus wird ersichtlich, dass bei einer Normalbetätigungskraft der Handhabe von wenigstens zehn Newton die Handhabe als feststehend anzusehen ist. Die Sensorelektronik ist so ausgelegt und ausgebildet, dass sie eine Normalbetätigungskraft von mindestens zehn Newton erfasst. Eine darunter liegende Kraft wird von der Sensorelektronik nicht detektiert, so dass dementsprechend auch nicht die Tür elektrisch geöffnet wird.For both the first and the second embodiment is provided in an embodiment of the invention that the predetermined restoring force of the mechanical retaining element is between at least sixty Newton and at most one hundred Newton. It is particularly preferred if the predetermined restoring force of the mechanical retention element is eighty-five Newtons (85N). It can be seen that at a normal operating force of the handle of at least ten Newton the handle is to be regarded as fixed. The sensor electronics are designed and configured to sense a normal operating force of at least ten Newton. An underlying force is not detected by the sensor electronics, so that accordingly not the door is opened electrically.

Der wesentliche Unterschied ist der, dass das elastische Federelement 43 nicht direkt auf die Handhabe 4 einwirkt, sondern die Handhabe 4 indirekt über den Umlenkhebel 41 in der Notbetätigungsposition hält, so dass in einem Notfall die Handhabe 4 erst dann von dem Träger 8 weg ausgelenkt und die Tür 2 rein mechanisch geöffnet werden können, wenn mit einer Notbetätigungskraft an der Handhabe 4 gezogen wird, welche größer als die von dem elastischen Federelement 43 auf die Handhabe 4 ausgeübte Rückstellkraft 24 ist. Denn in einem Notfall bei stromlosem Fahrzeugsystem kann durch eine Betätigung der Handhabe 4 eine mechanische Öffnung der Tür 2 bewirkt werden, während im Normalbetrieb die Handhabe 4 bei Betätigung mit der Normalbetätigungskraft 23 feststehend an der Tür und damit unbewegt verbleibt. Auch bei der zweiten Ausführungsform muss im Notfall die Handhabe 4 mit der von dem Träger 8 weg gerichteten Notbetätigungskraft (siehe Pfeil 31) betätigt werden, die größer als die vorbestimmte Rückstellkraft 12 ist, wie es in
Sowohl für die erste als auch für die zweite Ausführungsform beträgt die vorbestimmte Rückstellkraft 24 des mechanischen Rückhalteelements 12 zwischen wenigstens sechzig Newton und höchstens einhundert Newton, wobei die Normalbetätigungskraft der Handhabe 4 wenigstens zehn Newton beträgt.For both the first and second embodiments, the predetermined restoring
Zusammenfassend wird mit der vorliegenden Erfindung eine Türgriffanordnung 3 für ein Kraftfahrzeug 1 beschrieben, die sich durch eine pseudo-feststehende Handhabe 4 auszeichnet. Der Ausdruck "pseudo-feststehend" meint im Zusammenhang mit der Erfindung, dass die Handhabe 4 bei normaler Betätigung keine mechanische Wirkungskette zum Entriegeln aufweist, sondern die Entriegelung allein durch das elektromechanische Schließsystem 7 erfolgt, welches aufgrund der Detektion einer Betätigung der Handhabe 4 durch die Sensorelektronik 6 angesteuert wird. Die Handhabe 4 ist nur in einem Notfall, bei welchem eine strombetriebene Öffnung der Tür nicht möglich ist, auslenkbar, wobei dazu eine Betätigungskraft erforderlich ist, die weit über der Normalbetätigungskraft liegt und die die Rückstellkraft 24 des Rückhalteelements 12 überwindet. Dementsprechend ist es für die vorliegende Erfindung kennzeichnend, dass das mechanische Rückhalteelement 12 auf das zweite Längsende 11 der Handhabe 4 die vorbestimmte Rückhaltekraft 24 in Richtung des Trägers 8 ausübt und die Handhabe 4 in der unausgelenkten Normalbetätigungsposition hält, wobei die Sensorelektronik 6 bei Detektion einer Betätigung der Handhabe 4 durch einen Benutzer mit einer von dem Träger 8 weg gerichteten Normalbetätigungskraft 23, die kleiner als die vorbestimmte Rückstellkraft 24 ist, die Tür 2 oder Klappe elektrisch öffnet und dabei die Handhabe 4 in ihrer Normalbetätigungsposition angeordnet verbleibt. Die Handhabe 4 ist bei einer Betätigung der Handhabe 4 mit einer von dem Träger 8 weg gerichteten Notbetätigungskraft 31, die größer als die vorbestimmte Rückstellkraft 24 ist, in eine Notbetätigungsposition auslenkbar ist, in welcher die Auslenkbewegung der Handhabe 4 die Tür 2 oder Klappe mechanisch öffnet.In summary, the present invention describes a
