Description

Die Erfindung betrifft eine Vorrichtung zum Betätigen einer nach oben schwenkbaren Heckklappe an Kraftfahrzeugen nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for actuating an upwardly pivotable Tailgate on motor vehicles according to the preamble of claim 1.

Insbesondere an Kombi- / Schrägheckfahrzeugen sind seit langem Mittel zum offen halten bzw. selbsttätigen Öffnen von Heckklappen bekannt, deren Scharniere im Bereich des Fahrzeugdaches an tragenden Bauteilen, wie dem hinteren Dachquerträger, befestigt sind.On combi / hatchback vehicles in particular, means have long been open hold or automatically open tailgates known, their hinges in the area the vehicle roof on load-bearing components, such as the rear roof cross member, are attached.

Mit der DE 29 46 259 A1 wird beispielsweise eine sogenannte Gasdruckfeder, hier als Gasfeder bezeichnet, offenbart, die sich an der Karosserie und der Heckklappe abstützt und im Wesentlichen dem Gewichtsausgleich derselben im geöffneten Zustand dient.DE 29 46 259 A1 describes, for example, a so-called gas pressure spring, here as Designated gas spring, disclosed, which is supported on the body and the tailgate and essentially serves to balance the weight in the open state.

Um das Öffnen von großen Heckklappen komfortabler zu gestalten, sind des Weiteren selbsttätig öffnende und schließende Heckklappen bekannt, wobei sowohl elektromotorische als auch hydraulische oder pneumatische Mechanismen vorgeschlagen werden.In order to make opening large tailgates more convenient, there are also automatically opening and closing tailgates known, both electromotive as well as hydraulic or pneumatic mechanisms be proposed.

Durch die DE 37 44 083 C2 ist eine elektromotorische Öffnungs- und Schließvorrichtung an einer Heckklappe bekannt, die ihrerseits sich aus einem an der Innenseite des Daches und neben der Gelenkachse der Heckklappe angeordneten Antrieb in Form eines Elektromotors besteht, der seinerseits mittels einer Seilrolle, zwei über dieselbe in geschlossener Schleife geführte Seilzüge antreibt, die ihrerseits je ein seitlich der Heckklappe in einer Führungsbahn der Karosserie verschiebbar geführtes Gleitstück betätigen, welches jeweils über eine gelenkig gelagerte Betätigungsstange mit der Heckklappe verbunden ist. Diese nicht mehr zeitgemäße Lösung wird aufgrund der erforderlichen Umlenkungen für die Seilzüge sowie der Führungselemente als äußerst kompliziert und störanfällig eingeschätzt, woraus wiederum ein hoher Fertigungs- und Wartungsaufwand resultiert.DE 37 44 083 C2 is an electromotive opening and closing device known on a tailgate, which in turn consists of a on the inside of the Roof and next to the hinge axis of the tailgate arranged drive in shape an electric motor, which in turn by means of a pulley, two over the same in closed loop drives guided cables, which in turn each one to the side Tailgate slidably guided in a guideway of the body actuate which with an articulated operating rod with the Tailgate is connected. This outdated solution is due to the required deflections for the cables and the guide elements as extreme complicated and prone to failure, which in turn results in a high manufacturing and Maintenance effort results.

Auch durch die DE 196 15 021 A1 wird eine elektromotorische Öffnungs- und Schließvorrichtung an einer Heckklappe mittels Seilzug offenbart, wobei als Antrieb der Scheibenwischermotor der Heckklappe vorgeschlagen wird. Gleichfalls werden durch diese Druckschrift Hydraulik- oder Pneumatikantriebe vorgeschlagen, wobei vorliegend beidseitig der Heckklappe Hydraulikzylinder angelenkt sind, die sich jeweils mittels einer Kolbenstange an der Karosserie abstützen. Die Hydraulikzylinder selbst sind mit einem vom Scheibenwischermotor betriebenen Hydraulikmotor verbunden. Aufgrund der Tatsache, daß ein Großteil der erforderlichen Aggregate an der Heckklappe selbst angeordnet sind, baut diese äußerst schwer. Weiterhin ist als nachteilig einzuschätzen, daß infolge der Anordnung von zwei getrennt voneinander wirkenden Hydraulikzylindern eine gleichmäßige Krafteinwirkung auf die Heckklappe nicht immer gewährleistet ist und damit ein nachteiliges Verwinden derselben nicht ausgeschlossen werden kann, woraus in der Praxis wiederum erhebliche Verstärkungsmaßnahmen an der Heckklappe resultieren.DE 196 15 021 A1 also discloses an electromotive opening and closing mechanism Locking device on a tailgate disclosed by means of a cable, the drive being the Tailgate wiper motor is proposed. Likewise, through this publication proposed hydraulic or pneumatic drives, in the present case Hydraulic cylinders are articulated on both sides of the tailgate, which are each by means of a Support the piston rod on the body. The hydraulic cylinders themselves are with one hydraulic motor operated by the wiper motor. Due to the The fact that a large part of the required units on the tailgate itself are arranged, this builds extremely difficult. Furthermore, it can be assessed as disadvantageous that due to the arrangement of two separate hydraulic cylinders a uniform force on the tailgate is not always guaranteed and so that an adverse twisting of the same cannot be ruled out, from which in practice, considerable reinforcement measures on the tailgate result.

In Verbesserung vorstehender Lösung wurden gemäß der US 6,115,965 wesentliche Aggregateteile der Hydraulikanlage in den Kofferraum des Kraftfahrzeugs verlegt. Als nachteilig ist jedoch auch hier die störende Anordnung der Hydraulikzylinder seitlich der Heckklappe einzuschätzen.According to US Pat. No. 6,115,965, improvements in the above solution were essential Parts of the hydraulic system in the trunk of the motor vehicle. As disadvantageous, however, is the disruptive arrangement of the hydraulic cylinders laterally Assess tailgate.

Die EP 0 959 212 A1 zeigt fernerhin eine Betätigungsanordnung für bewegliche Teile an Fahrzeugen, wie Heckdeckel, wobei die Antriebseinrichtung in Form eines Hydraulikzylinders zum Öffnen und Schließen des Heckdeckels innerhalb einer Längsebene der Kraftfahrzeugkarosserie angeordnet ist und an einem Scharnier des Heckdeckels angreift. Auch hier sind bei einseitiger Kraftaufbringung Verwindungen des Heckdeckels nicht auszuschließen. Des Weiteren sind durch die Anordnung des Hydraulikzylinders beispielsweise im Kofferraum Verluste an Stauraum zu verzeichnen.EP 0 959 212 A1 furthermore shows an actuation arrangement for moving parts Vehicles such as trunk lids, the drive device in the form of a Hydraulic cylinder for opening and closing the boot lid within one Longitudinal plane of the motor vehicle body is arranged and on a hinge of the Tailgate attacks. Here, too, are twists of the Rear lid cannot be excluded. Furthermore, the arrangement of the Hydraulic cylinders, for example, in the trunk loss of storage space.

Hier setzt die nachfolgend beschriebene Erfindung an.This is where the invention described below comes into play.

Aufgabe der vorliegender Erfindung ist es, die Nachteile des geschilderten Standes der Technik zu vermeiden und demgemäß in Verbesserung desselben eine einfache und kostengünstige Vorrichtung der eingangs genannten Gattung zu schaffen, die zum einen Verluste an Stauraum und eine Behinderung der freien Durchsicht weitestgehend ausschließt respektive auf störende Aggregate bzw. Bauteile im Bereich der Heckklappe verzichtet, zum anderen eine vorteilhaftere Kraftaufbringung auf die Klappenstruktur erzielt und demgemäß nachteilige Effekte, wie Verwindungen derselben vermeidet.The object of the present invention is to overcome the disadvantages of the state of the art Avoid technology and, accordingly, improve it in a simple and To create inexpensive device of the type mentioned, the one Loss of storage space and a hindrance to the clear view as far as possible excludes or disruptive aggregates or components in the area of the tailgate waived, on the other hand, a more advantageous application of force to the flap structure achieved and accordingly prevents adverse effects such as twisting the same.

Erfindungsgemäß wird die Aufgabe in Verbindung mit den Merkmalen im Oberbegriff des Anspruchs 1 dadurch gelöst, daß die Vorrichtung zumindest einen quer zur Fahrzeuglängsachse an einem zu den Scharnieren und/oder dem oberen Querholm der Heckklappe benachbarten Abschnitt der Kraftfahrzeugkarosserie angeordneten Linearantrieb umfaßt, der seinerseits mittels an der Kraftfahrzeugkarosserie angeordneter Kraftumlenkelemente mit der Heckklappe und/oder den Scharnieren, eine Schwenkbewegung der Heckklappe realisierend und/oder unterstützend, in Wirkverbindung steht. Der Linearantrieb ist erfindungsgemäß als aktiv oder passiv wirkender Linearantrieb ausgebildet, wobei der aktiv wirkende Linearantrieb hydraulisch, pneumatisch oder elektrisch betrieben und der passiv wirkende Linearantrieb eine Gasdruckfeder ist.According to the invention the task in connection with the features in the preamble of Claim 1 solved in that the device at least one transverse to Vehicle longitudinal axis on one of the hinges and / or the upper cross member of the Tailgate adjacent portion of the motor vehicle body arranged Linear drive comprises, which in turn by means of the motor vehicle body arranged force deflection elements with the tailgate and / or the hinges, one Realizing and / or supporting pivoting movement of the tailgate, in Active connection is established. According to the invention, the linear drive is active or passive acting linear drive, the active acting linear drive being hydraulic, pneumatically or electrically operated and the passive linear actuator Is gas spring.

In Weiterbildung der Erfindung ist vorgesehen, daß der Linearantrieb und die Kraftumlenkelemente so ausgebildet sind, daß dieselben an wenigstens zwei voneinander beabstandeten Angriffspunkten sowie synchron und mit gleicher Kraft auf die Heckklappe und/oder deren Scharniere einwirken und die Angriffspunkte derart gewählt sind, daß die einwirkende Kraft weitestgehend gleichmäßig auf die Klappenstruktur verteilt und ein Verwinden der Heckklappe vermieden wird.In a development of the invention it is provided that the linear drive and the Force deflection elements are designed so that the same at least two spaced apart attack points as well as synchronously and with the same force act on the tailgate and / or its hinges and the points of attack in this way are chosen so that the force acting largely evenly on the Flap structure is distributed and twisting of the tailgate is avoided.

Die Kraftumlenkung vom Linearantrieb auf die Heckklappe kann sowohl nach einem Hebelprinzip als auch nach einem Schieberprinzip realisiert sein.The force redirection from the linear drive to the tailgate can be done after a Lever principle as well as be implemented according to a slide principle.

Weiterhin wird im Sinne der Erfindung vorgeschlagen, daß der Linearantrieb stirnseitig an den Kraftumlenkelementen aufgehängt ist.Furthermore, it is proposed in the sense of the invention that the linear drive end is suspended from the force deflection elements.

Wie die Erfindung weiter vorsieht, ist im Falle der Verwendung eines hydraulisch oder pneumatisch betriebenen und aktiv wirkenden Linearantriebs oder eines passiv wirkenden Linearantriebs in Form einer Gasdruckfeder das Kraftübertragungsmittel derselben durch eine Kolbenstange und bei einem aktiven wirkenden elektrisch betriebenen Linearantrieb durch eine Zahn- oder Gewindestange gebildet.As the invention further provides, in the case of using a hydraulic or pneumatically operated and active linear actuator or a passive acting linear drive in the form of a gas pressure spring the power transmission means the same through a piston rod and with an active acting electrical operated linear drive formed by a toothed or threaded rod.

Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist einem aktiv wirkenden Linearantrieb wenigstens ein weiterer, jedoch passiv wirkender Linearantrieb in Form einer Gasdruckfeder zugeordnet. Schließlich wird es als zweckmäßig erachtet, daß der weitere passiv wirkende Linearantrieb in Form der Gasdruckfeder ähnlich dem aktiv wirkenden Linearantrieb quer zur Fahrzeuglängsachse angeordnet ist und über die Kraftumlenkelemente des aktiv wirkenden Linearantriebs oder über eigene Kraftumlenkelemente mit der Heckklappe und/oder deren Scharnieren in Wirkverbindung steht.According to a further advantageous embodiment of the invention, one is active acting linear drive at least one other, but passive acting linear drive assigned in the form of a gas pressure spring. Finally, it is considered appropriate that the further passive linear actuator in the form of the gas pressure spring similar to that active linear actuator is arranged transversely to the longitudinal axis of the vehicle and over the Force deflection elements of the active linear actuator or via your own Force deflection elements with the tailgate and / or its hinges in operative connection stands.

Fig. 1 zeigt schematisch die Heckansicht eines Kraftfahrzeugs, vorliegend eines Kombifahrzeuges mit einer nach oben geschwenkten Heckklappe 1, welche ihrerseits in an sich bekannter Weise mittels oben liegender Scharniere 2 an der Kraftfahrzeugkarosserie 3 angebunden und mittels einer Vorrichtung zum Betätigen der Heckklappe 1 in Form eines Linearantriebs 4 in Offen-Stellung gehalten ist. Der Linearantrieb 4 erstreckt sich vorliegend einseitig zwischen der Kraftfahrzeugkarosserie 3 und der Heckklappe 1 und ist an diesen angelenkt.Fig. 1 shows schematically the rear view of a motor vehicle, in the present case one Combined vehicle with a tailgate 1 pivoted upwards, which in turn in in a known manner by means of hinges 2 on the Motor vehicle body 3 connected and by means of a device for actuating the Tailgate 1 in the form of a linear drive 4 is held in the open position. The In the present case, linear drive 4 extends on one side between motor vehicle body 3 and the tailgate 1 and is hinged to this.

Als Linearantriebe 4 haben sich sowohl aktiv wirkende als auch passiv wirkende Linearantriebe 4a; 4b bewährt, wobei aktiv wirkende Linearantriebe 4a hydraulisch, pneumatisch oder elektrisch (elektromotorisch) betrieben sein können. Hydraulisch und pneumatisch betriebene Linearantriebe 4a sind üblicherweise als sogenannte Kolben-Zylinder-Einheiten ausgebildet. Elektrisch betriebene Linearantriebe 4a können dagegen eine in einer angetriebenen Gewindemutter geführte Gewindestange aufweisen, die ihrerseits durch Drehung der Gewindemutter axial bewegt wird, ebenso ist auch eine mit einem Ritzel in Wirkverbindung stehende Zahnstange denkbar (nicht näher dargestellt). Mittels aktiv wirkender Linearantriebe 4a wird eine Heckklappe 1 beispielsweise nach Betätigung eines Schalters zunächst entriegelt sowie nachfolgend durch Aktivierung des Linearantriebs 4a in eine Offen-Stellung bewegt und abschließend nach nochmaliger Betätigung eines Schalters in die Ausgangsstellung (Geschlossen-Stellung) zurück bewegt und wieder verriegelt.Linear drives 4 have both active and passive ones Linear drives 4a; 4b proven, with active linear drives 4a hydraulic, can be operated pneumatically or electrically (electromotive). Hydraulic and pneumatically operated linear drives 4a are usually known as piston-cylinder units educated. Electrically operated linear drives 4a, however, can have a threaded rod guided in a driven threaded nut, which is in turn moved axially by turning the threaded nut, as is one with a rack that is operatively connected to a pinion is conceivable (not shown in detail). A tailgate 1 is moved, for example, by means of active linear drives 4a Activation of a switch initially unlocked and then by activating the Linear drive 4a moved into an open position and finally after repeated Actuation of a switch back to the starting position (closed position) moved and locked again.

Passiv wirkende Linearantriebe 4b sind für vorliegenden Anwendungsfall vorzugsweise als an sich bekannte Gasdruckfedern ausgebildet, die ihrerseits aus einer in einem Zylinder geführten Kolbenstange bestehen und im Wesentlichen die Schwenkbewegung der Heckklappe 1 unterstützen bzw. als Gewichtsausgleich fungieren und eine bereits manuell geöffnete Heckklappe 1 in einer Offen-Stellung halten.Passive linear drives 4b are preferred for the present application as known gas pressure springs, which in turn consist of one in one Cylinder-guided piston rod exist and essentially the swivel movement the tailgate 1 support or act as a weight balance and one already Hold the manually opened tailgate 1 in an open position.

Wie bereits oben in den Ausführungen zum Stand der Technik näher dargelegt, ist bei einseitiger Anordnung der Linearantriebe 4a; 4b ein Verwinden der Heckklappe 1 nicht auszuschließen. Unabhängig davon, daß dieser Mißstand durch beidseitige Anordnung von Linearantrieben 4a; 4b sicherlich leicht zu beheben ist, ist insbesondere bei aktiv wirkenden Linearantrieben 4a ein erheblicher technischer Aufwand für die Synchronisation derselben erforderlich. Auch bei Verwendung von zwei beidseitig der Heckklappe 1 angeordneten passiv wirkenden Linearantrieben 4b ist eine hohe Abstimmung derselben zueinander angezeigt. Schließlich wirkt sich diese bekannte Anordnung störend beim Be- bzw. Entladen des Kraftfahrzeuges aus. As already explained in more detail above in the explanations on the prior art, at one-sided arrangement of the linear drives 4a; 4b does not twist the tailgate 1 excluded. Regardless of the fact that this maladministration by bilateral arrangement of linear drives 4a; 4b is certainly easy to fix, especially when active acting linear drives 4a a considerable technical effort for the Synchronization of the same is required. Even when using two on both sides of the Tailgate 1 arranged passively acting linear drives 4b is a high Matching them to each other is displayed. Finally, this familiar affects Arrangement disruptive when loading or unloading the motor vehicle.

Die Fig. 2 zeigt demgegenüber schematisch die erfindungsgemäße Anordnung eines einzigen Linearantriebs 4, vorliegend eines aktiv wirkenden und hydraulisch betriebenen Linearantriebs 4a, wobei die Medienleitungen 5 für den Linearantrieb 4a lediglich angedeutet und bevorzugt verdeckt in Hohlräumen der Kraftfahrzeugkarosserie 3 verlegt sind.2 shows, in contrast, the arrangement of a single linear drive 4, in the present case an actively acting and hydraulically operated Linear drive 4a, the media lines 5 for the linear drive 4a only indicated and preferably laid hidden in cavities of the motor vehicle body 3 are.

Danach ist dieser Linearantrieb 4a quer zur Fahrzeuglängsachse, demgemäß in Y-Richtung der Kraftfahrzeugkarosserie 3 an einem zu den Scharnieren 2 und/oder dem oberen Querholm 6 der Heckklappe 1 benachbarten Abschnitt der Kraftfahrzeugkarosserie 3 angeordnet.Thereafter, this linear drive 4a is transverse to the longitudinal axis of the vehicle, accordingly in the Y direction the motor vehicle body 3 on one of the hinges 2 and / or the upper cross member 6 of the tailgate 1 adjacent section of Motor vehicle body 3 arranged.

Wie in den Fig. 3 und 4 näher gezeigt, steht der Linearantrieb 4a mittels an der Kraftfahrzeugkarosserie 3 angeordneter Kraftumlenkelemente 7 in Form zweier an sich bekannter Hebelsystems mit der nicht näher dargestellten Heckklappe 1 respektive den Scharnieren 2 in Wirkverbindung. Vorliegend bestehen die Kraftumlenkelemente 7 jeweils aus einem an der Kraftfahrzeugkarosserie 3 schwenkbeweglich angeordneten Schwenkhebel 7a, der einerends mit dem Linearantrieb 4a und anderenends über eine schwenkbeweglich gelagerte Kugelkopfaufnahme 7b mit einer Hebelanbindung 7c des Scharniers 2 verbunden ist. Durch eine axiale Bewegung des Linearantriebs 4a kann somit ein Moment auf die Scharniere 2 aufgebracht und demgemäß eine Schwenkbewegung der Heckklappe 1 realisiert werden.As shown in FIGS. 3 and 4 in more detail, the linear drive 4a is at the Motor vehicle body 3 arranged force deflection elements 7 in the form of two per se Known lever system with the tailgate 1, not shown, respectively Hinges 2 in operative connection. In the present case, there are the force deflection elements 7 each of which is arranged on the motor vehicle body 3 so as to be pivotable Swivel lever 7a, one end with the linear drive 4a and the other end with a pivotally mounted ball head receptacle 7b with a lever connection 7c of the Hinge 2 is connected. An axial movement of the linear drive 4a can thus a moment applied to the hinges 2 and accordingly one Swiveling movement of the tailgate 1 can be realized.

In der bevorzugten Ausführungsform sind die Kraftumlenkelemente 7 im Bereich des Himmels 8 der Fahrzeugkarosserie 3 am hinteren Dachquerträger 9 in unmittelbarer Nähe der Scharniere 2 angeordnet (Fig. 3).In the preferred embodiment, the force deflection elements 7 are in the region of the Sky 8 of the vehicle body 3 on the rear roof cross member 9 in the immediate vicinity Arranged near the hinges 2 (Fig. 3).

Für den Fachmann ist sicherlich leicht nachvollziehbar, daß vorteilhafter Weise der Linearantrieb 4a und die Kraftumlenkelemente 7 so ausgebildet sein sollten, daß dieselben an wenigstens zwei voneinander beabstandeten Angriffspunkten sowie synchron und mit gleicher Kraft auf die Heckklappe 1 und/oder deren Scharniere 2 einwirken und die Angriffspunkte derart zu wählen sind, daß die einwirkende Kraft weitestgehend gleichmäßig auf die Klappenstruktur verteilt und ein Verwinden der Heckklappe 1 vermieden wird. For the expert it is certainly easy to understand that the advantageous Linear drive 4a and the force deflection elements 7 should be designed so that the same at at least two attack points spaced apart from one another and synchronously and with the same force on the tailgate 1 and / or its hinges 2 act and choose the points of attack so that the acting force largely evenly distributed on the flap structure and a twisting of the Tailgate 1 is avoided.

Zum einen wird dieses Erfordernis schon, wie in Fig. 3 gezeigt, dadurch erfüllt, daß die Angriffspunkte sich im Bereich der nahezu symmetrisch zur Fahrzeuglängsachse und möglichst weit voneinander angeordneten Scharniere 2 befinden, zum anderen in besonders vorteilhafter Weise der Linearantrieb 4a stirnseitig an den beiden Kraftumlenkelementen 7 respektive deren Schwenkhebel 7a aufgehängt ist. Durch diese Maßnahme wird die aufgebrachte Kraft exakt gleichmäßig auf die Scharniere 2 und demgemäß auch auf die Klappenstruktur aufgeteilt.On the one hand, this requirement is already met, as shown in Fig. 3, that the Points of attack are in the area of almost symmetrical to the vehicle's longitudinal axis and Hinges 2 arranged as far apart from one another as possible in FIG particularly advantageously, the linear drive 4a on the front side of the two Force deflection elements 7 or their pivot lever 7a is suspended. Through this Measure, the applied force is exactly even on the hinges 2 and accordingly also divided into the valve structure.

Wie bereits oben dargetan, können die aktiven Linearantriebe 4a Kraftübertragungsmittel 10 in Form entweder einer Kolbenstange oder einer Zahn- oder Gewindestange aufweisen. Es versteht sich somit von selbst, daß der Linearantrieb 4a zum einen mit dem Kraftübertragungsmittel 10 und zum anderen mit dem Gehäuse, welches beispielsweise der Zylinder 11 einer Kolben-Zylinder-Einheit sein kann, am jeweils zugeordneten Kraftumlenkelement 7 angebunden ist. Ebenso ist es denkbar, an sich bekannte doppelt wirksame Linearantriebe 4a zu verwenden, die ihrerseits jeweils über zwei Kraftübertragungsmittel 10 verfügen, die in entgegengesetzter Richtung axial bewegt werden und mit ihrem freien Ende mit dem zugeordneten Kraftumlenkelement 7 verbunden sind (nicht näher dargestellt).As already shown above, the active linear drives 4a can transmit power 10 in the form of either a piston rod or a toothed or threaded rod exhibit. It goes without saying that the linear drive 4a on the one hand the power transmission means 10 and the other with the housing, which For example, the cylinder 11 of a piston-cylinder unit can be on each associated force deflection element 7 is connected. It is also conceivable in itself known double-acting linear drives 4a to use, which in turn each over have two power transmission means 10 axially in the opposite direction are moved and with their free end with the associated force deflection element 7 are connected (not shown).

Das Ausführungsbeispiel gem. den Fig. 5 und 6 unterscheidet sich zum vorbeschriebenen lediglich dadurch, daß statt eines aktiv wirkenden Linearantriebs 4a ein ebenfalls quer zur Fahrzeuglängsachse angeordneter, jedoch passiv wirkender Linearantrieb 4b Verwendung findet, der seinerseits als Gasdruckfeder ausgebildet ist und bei manuellem Öffnen der Heckklappe 1 als Gewichtsausgleich fungiert.The embodiment according to. 5 and 6 differs to described above only in that instead of an active linear actuator 4a one that is also arranged transversely to the longitudinal axis of the vehicle, but has a passive effect Linear drive 4b is used, which in turn is designed as a gas pressure spring and acts as a weight counterbalance when the tailgate 1 is opened manually.

Als ebenfalls denkbar wird angesehen und durch die Erfindung mit erfaßt, einem aktiv wirkenden Linearantrieb 4a wenigstens einen weiteren passiv wirkenden Linearantrieb 4b zuzuordnen (nicht näher dargestellt). Dieses macht insbesondere dann Sinn, wenn bei Verwendung eines hydraulisch betriebenen Linearantriebs 4a derselbe bei geöffneter Heckklappe 1 drucklos geschaltet wird und somit der passiv wirkende Linearantrieb 4b in Form der Gasdruckfeder die Offen-Stellung der Heckklappe 1 gewährleistet.Is also considered to be conceivable and also included by the invention, one active acting linear drive 4a at least one further passively acting linear drive 4b assign (not shown in detail). This makes sense especially when Use of a hydraulically operated linear drive 4a the same when open Tailgate 1 is depressurized and thus the passive linear actuator 4b in Shape of the gas pressure spring ensures the open position of the tailgate 1.

Darüber hinaus wird bei einem Systemausfall des gewählten aktiven Systems eine weitere Betätigung mittels des passiv wirkenden Linearantriebs 4b gewährleistet. In addition, if the selected active system fails, a further actuation by means of the passive linear actuator 4b guaranteed.

Hierbei ist in einer bevorzugten Anordnung der weitere passiv wirkende Linearantrieb 4b ähnlich dem aktiv wirkenden Linearantrieb 4a quer zur Fahrzeuglängsachse und nahezu parallel zum demselben angeordnet und steht über die Kraftumlenkelemente 7 des aktiv wirkenden Linearantriebs 4a oder über eigene Kraftumlenkelemente 7 mit der Heckklappe 1 und/oder deren Scharnieren 2 in Wirkverbindung. Selbstverständlich ist auch eine herkömmliche Anordnung des passiv wirkenden Linearantriebs 4b seitlich der Heckklappe 1 unter Inkaufnahme der daraus resultierenden bereits oben beschriebenen Nachteile denkbar und durch die Erfindung ebenfalls mit erfaßt.Here, in a preferred arrangement, there is the further passive linear actuator 4b Similar to the active linear actuator 4a transverse to the vehicle's longitudinal axis and almost arranged parallel to the same and stands over the force deflection elements 7 of the active acting linear actuator 4a or via its own force deflection elements 7 with the Tailgate 1 and / or its hinges 2 in operative connection. It goes without saying also a conventional arrangement of the passive linear actuator 4b to the side of the Tailgate 1 while accepting the resultant already described above Disadvantages conceivable and also covered by the invention.

Schließlich ist in den Fig. 7 und 8 eine weitere Ausführung einer geeigneten Kraftumlenkung vom Linearantrieb 4a; 4b auf die Scharniere 2 respektive die nicht näher dargestellte Heckklappe 1 gezeigt. Diese ist nach einem sogenannten Schieberprinzip realisiert, wobei zwei keilförmig ausgebildete und aufeinander gleitende Schieberelemente 12; 13 in Seitenführungen 14 und fernerhin zueinander nach Art einer Schwalbenschwanzführung 15 geführt sind. Vorliegend ist das Schieberelement 12 mit dem Linearantrieb 4a; 4b und das Schieberelement 13 mit einem Scharnier 2 verbunden.Finally, another embodiment of a suitable one is shown in FIGS Force deflection from the linear drive 4a; 4b on the hinges 2 or not shown tailgate 1 shown. This is based on a so-called slide principle realized, two wedge-shaped and sliding on each other Slide elements 12; 13 in side guides 14 and further to each other in the manner of a Dovetail guide 15 are guided. In the present case, the slide element 12 is included the linear drive 4a; 4b and the slide element 13 connected to a hinge 2.
