Description

Heckklappe eines Kraftfahrzeugs Tailgate of a motor vehicle
Die Erfindung betrifft eine Heckklappe eines Kraftfahrzeugs mit zumindest einem Klappenteil, das mittels einer Schwenklagereinrichtung am Fahrzeugheck schwenkbar gelagert und aus seiner Schließstellung nach oben in eine Offenstellung verschwenkbar ist.The invention relates to a tailgate of a motor vehicle with at least one flap part which is pivotally mounted on the rear of the vehicle by means of a pivot bearing device and can be pivoted upward from its closed position into an open position.
Aus der DE 44 00 786 C1 ist eine derartige Heckklappe bekannt geworden, bei der das obere wie auch das untere Klappenteil jeweils um eine fahrzeugfeste horizontale Schwenkachse schwenkbar gelagert ist und dafür lediglich einfache Scharnieranordnungen erforderlich sind. Die Heckklappe kann teilweise geöffnet werden, indem nur das obere Klappenteil nach oben geschwenkt wird, oder sie wird vollständig geöffnet, indem beide Klappenteile nach oben geschwenkt werden. Die Schwenkwinkel der beiden Klappenteile und die Anordnung der beiden Schwenkachsen kann so aufeinander abgestimmt sein, daß die beiden Klappenteile in ihrer geöffneten Endposition etwa parallel übereinander positionierbar sind.Such a tailgate has become known from DE 44 00 786 C1, in which the upper and the lower flap parts are each pivotably mounted about a horizontal swivel axis fixed to the vehicle and only simple hinge arrangements are required for this. The tailgate can be partially opened by pivoting only the upper flap part upwards, or it can be fully opened by pivoting both flap parts upwards. The swivel angle of the two flap parts and the arrangement of the two swivel axes can be coordinated with one another such that the two flap parts can be positioned approximately parallel one above the other in their open end position.
Aus der FR 2 809 676 A1 ist eine unterteilte Heckklappe bekannt geworden, bei der das obere Klappenteil an seinem Oberrand um eine feste Schwenkachse an der Karosserie schwenkbar gelagert ist und das untere Klappenteil mittels einer Viergelenkanordnung an dem oberen Klappenteil angelenkt ist. Somit kann das untere Klappenteil nach oben an die Außenseite des oberen Klappenteils geschwenkt werden und mit dem oberen Klappenteil in eine Offenstellung der Heckklappe verschwenkt werden. Da das untere Klappenteil am oberen Klappen- teil gelagert ist, muß dessen Lagerung auf dieses zusätzliche Gewicht ausgelegt und abgestimmt sein.From FR 2 809 676 A1, a divided tailgate has become known, in which the upper flap part is pivotally mounted on its upper edge about a fixed pivot axis on the body and the lower flap part is articulated on the upper flap part by means of a four-bar arrangement. The lower flap part can thus be pivoted upwards to the outside of the upper flap part and pivoted with the upper flap part into an open position of the tailgate. Since the lower flap part on the upper flap is stored in part, its storage must be designed and matched to this additional weight.
Aufgabe der Erfindung ist es, eine eingangs genannte Heckklappe zu schaffen, die in Bezug auf ihre Funktionalität verbessert ist.The object of the invention is to provide a tailgate mentioned at the outset which is improved in terms of its functionality.
Die Aufgabe wird bei der eingangs genannten Heckklappe erfindungsgemäß dadurch gelöst, daß die Schwenklagereinrichtung seitlich jeweils zwei Schwenkhebel in Vier- oder Mehrgelenkanordnung aufweist, die einerseits karosserieseitig angelenkt sind und an denen andererseits jeweils mittels eines Schwenkgelenks das Klappenteil angelenkt ist, daß das Schwenkgelenk des ersten Schwenkhebels am Klappenteil zumindest zeitweise feststeht und das Schwenkgelenk des zweiten Schwenkhebels an einer am Klappenteil angeordneten Führung relativ zum ersten Schwenkgelenk verschiebbar gelagert ist und daß eine Steuereinrich- tung die Schwenkbewegung des zweiten Schwenkhebels beim Öffnen undThe object is achieved according to the invention in the above-mentioned tailgate in that the pivot bearing device has two pivoting levers on each side in a four- or multiple-joint arrangement, which are articulated on the body side and to which the flap part is articulated by means of a pivoting joint that the pivoting joint of the first pivoting lever is at least temporarily fixed on the flap part and the swivel joint of the second swivel lever is mounted displaceably on a guide arranged on the flap part relative to the first swivel joint and that a control device detects the swivel movement of the second swivel lever when opening and
Schließen des Klappenteils derart steuert, daß das Schwenkgelenk des zweiten Schwenkhebels über seine Positionsveränderung relativ zum Schwenkgelenk des ersten Schwenkhebels ein Verschwenken des Klappenteils um das Schwenkgelenk des ersten Schwenkhebels bewirkt. Bei entsprechender Abstimmung der beiden Schwenkhebel kann somit ein Schwenkverhalten des Klappenteils eingestellt werden, das über das bei einer üblichen Vier- oder Mehrgelenkanordnung einstellbare Schwenkverhalten hinausgehen kann. Dabei können die Schwenkgelenke der beiden Schwenkhebel gegeneinander bewegbar sein oder das Schwenkgelenk des einen Schwenkhebels ist zeitweise oder ständig an dem Klappenteil festgelegt. Grundsätzlich kann jeder der beiden Schwenklenker mit dem Klappenteil zumindest zeitweise fest verbunden sein. Die gegenseitige Annäherung erfolgt dabei auf einer zweckgerichtet eingestellten Bewegungsbahn, wobei sich z. B. das bewegbare Schwenkgelenk des einen Schwenkhebels beim Öffnen des Klappenteils über das an dem Klappenteil feststehenden Schwenkge- lenk des anderen Schwenkhebels anhebt.Closing the flap part controls such that the swivel joint of the second swivel lever causes the flap part to swivel about the swivel joint of the first swivel lever via its change in position relative to the swivel joint of the first swivel lever. With a corresponding coordination of the two pivot levers, a pivoting behavior of the flap part can thus be set which can go beyond the pivoting behavior that can be set in a conventional four or multiple joint arrangement. The swivel joints of the two swivel levers can be movable relative to one another or the swivel joint of the one swivel lever is temporarily or permanently attached to the flap part. In principle, each of the two swivel links can be permanently connected to the flap part at least temporarily. The mutual approach takes place on a purposefully set movement path, with z. B. raises the movable swivel joint of one swivel lever when the flap part is opened via the swivel joint of the other swivel lever which is fixed to the flap part.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben. Vorzugsweise steuert die Steuereinrichtung den zweiten Schwenkhebel derart, daß das Klappenteil beim Öffnen über einen zusätzlichen Schwenkwinkel verschwenkt wird. Somit hebt sich z. B. das bewegbare Schwenkgelenk des unteren Schwenkhebels beim Öffnen des Klappenteils über das an dem Klappenteil feststehenden Schwenkgelenk des oberen Schwenkhebels an. Durch die Auslegung der Bewegungsbahnen der beiden Schwenkhebel kann somit ein fahrzeugnahes Parallelverschwenken des Klappenteils erfolgen, das z. B. nahe seiner oberen Offenstellung von einem starken Verschwenken des Klappenteils überlagert wird.Advantageous embodiments of the invention are specified in the subclaims. The control device preferably controls the second pivoting lever in such a way that the flap part is pivoted when opening over an additional pivoting angle. Thus, z. B. the movable swivel joint of the lower swivel lever when opening the flap part on the swivel joint of the upper swivel lever fixed on the flap part. By designing the trajectories of the two swivel levers, a parallel pivoting of the flap part can thus take place near the vehicle. B. is superimposed near its upper open position by a strong pivoting of the flap part.
Vorzugsweise enthält die Steuereinrichtung einen Steuerlenker, der die beiden Schwenkhebel jeweils zwischen ihren karosserieseitigen und klappenteilseitigen Schwenkgelenken miteinander gelenkig verbindet. Diese mechanische Kopplung ist eine besonders einfach gestaltete Steuerungseinrichtung, jedoch können auch z. B. motorisch verstellbare Steuereinrichtungen oder Steuerlenker verwendet werden, die eine Veränderung des Steuerverhaltens ermöglichen.The control device preferably contains a control link which connects the two swivel levers in an articulated manner between their swivel joints on the body side and on the flap part side. This mechanical coupling is a particularly simple control device, however, e.g. B. motorized control devices or control arms can be used, which allow a change in the control behavior.
Zweckmäßigerweise ist an der insbesondere stabformig gebildeten Führung eine Hülse oder ein vergleichbares Lagerteil verschiebbar gelagert, die bzw. das mit dem zweiten Schwenkhebel mittels eines Gelenks verbunden ist. Die Führung kann linear oder gekrümmt gebildet sein und kann an dem Klappenteil fest oder auch einstellbar oder beim Verschwenken auf einer Bewegungsbahn geführt sein.A sleeve or a comparable bearing part is expediently slidably mounted on the guide, which is in particular in the form of a rod, and is connected to the second pivoting lever by means of a joint. The guide can be linear or curved and can be fixed or adjustable on the flap part or can be guided on a movement path when pivoted.
Eine in bevorzugter Gestaltung am Fahrzeugheck angeordnete Verschwenkein- richtung kann mit einem der beiden Schwenkhebel des Klappenteils gekoppelt sein und eine manuelle Betätigung unterstützen oder entlasten oder eine selbsttätige Verschwenkbewegung erzeugen. Zweckmäßigerweise ist die Verschwenk- einrichtung mit einem Fortsatz des ersten, oberen Schwenkhebels gekoppelt, kann jedoch auch mit dem zweiten Schwenkhebel in geeigneter Weise gekoppelt sein.A pivoting device arranged in a preferred configuration on the rear of the vehicle can be coupled to one of the two pivoting levers of the flap part and can support or relieve manual actuation or generate an automatic pivoting movement. The pivoting device is expediently coupled to an extension of the first, upper pivoting lever, but can also be coupled in a suitable manner to the second pivoting lever.
Vorzugsweise enthält die Verschwenkeinrichtung eine Gasdruckfeder, eine Gaszugfeder oder eine insbesondere elektrisch oder hydraulisch betätigte An- triebseinrichtung, um das Verschwenken des Klappenteils zu unterstützen oder zu bewirken.The pivoting device preferably contains a gas pressure spring, a gas tension spring or a particularly electrically or hydraulically actuated attachment drive device to support or effect the pivoting of the flap part.
Eine bevorzugte Gestaltung sieht vor, daß das Klappenteil ein unteres Klappenteil der in ein oberes Klappenteil und ein unteres Klappenteil unterteilten Heckklappe ist. Grundsätzlich eignet sich die Schwenklagerung für jede Art von schwenkbar gelagerter Heckklappe oder einem Klappenteil einer Heckklappe.A preferred design provides that the flap part is a lower flap part of the tailgate divided into an upper flap part and a lower flap part. Basically, the swivel bearing is suitable for any type of swivel-mounted tailgate or a flap part of a tailgate.
Vorzugsweise ist das obere Klappenteil mittels einer Schwenklagerung am Fahr- zeugheck gelagert ist und das geöffnete untere Klappenteil ist neben der Innenseite des oberen Klappenteils angeordnet. Damit ergibt sich eine besonders kompakte Anordnung der beiden Klappenteile sowie ein geringer Schwenkraum.The upper flap part is preferably mounted on the rear of the vehicle by means of a pivot bearing and the open lower flap part is arranged next to the inside of the upper flap part. This results in a particularly compact arrangement of the two flap parts and a small swivel space.
Die beiden Klappenteile können zur gemeinsamen Schwenkbewegung miteinan- der gekoppelt sind, z. B. durch eine mechanische Kopplung mittels eines Bow- denzugs oder eines Lenkergetriebes. Andererseits kann auch eine jeweilige Antriebseinrichtung vorgesehen sein und die beiden Antriebseinrichtungen sind mittels einer elektronischen Steuerung steuerbar.The two flap parts can be coupled to one another for the joint pivoting movement, for. B. by a mechanical coupling by means of a Bowden cable or a steering gear. On the other hand, a respective drive device can also be provided and the two drive devices can be controlled by means of an electronic control.
Wenn ein Sensor zur Abstandserfassung vorgesehen ist, der ein Signal erzeugt, wenn ein Objekt das Öffnen der Heckklappe bzw. eines der Klappenteile be- oder verhindert, kann eine Beschädigung der Heckklappe bzw. der Klappenteile durch unsachgemäßes Öffnen verhindert werden.If a sensor for distance detection is provided, which generates a signal when an object obstructs or prevents the opening of the tailgate or one of the flap parts, damage to the tailgate or the flap parts by improper opening can be prevented.

Ein eine Hecköffnung aufweisendes Kraftfahrzeug (in den Figuren nicht näher dargestellt), beispielsweise ein Kombi oder ein SUV (sport Utility vehicle), enthält eine Heckklappe 1 zum Verschließen der Hecköffnung. Die Heckklappe 1 ist in ein oberes Klappenteil 2 und ein unteres Klappenteil 3 unterteilt. Das obere Klappenteil 2 ist mittels einer benachbart zu seinem Oberrand 4 angeordneten Lagereinrichtung an der Karosserie bzw. dem Fahrzeugheck um eine Querschwenkachse 5 schwenkbar gelagert, so daß es zwischen einer Schließstellung (Fig. 1 und 2) und einer Offenstellung (Fig. 3 und 4) verschwenkbar ist. Die Lagereinrichtung für das obere Klappenteil 2 enthält beidseits jeweils ein Scharnier oder Schwenkgelenk 6, das an der Karosserie am Fahrzeugdach z. B. im Bereich des Dachseitenholms oder am Oberende der D-Säule angeordnet ist. Eine jeweils im rechten und im linken Dachseitenholm angeordnete Gasdruckfeder 7 ist mit dem oberen Klappenteil 2 bzw. mit einem mit dem oberen Klappenteil 2 verbundenen Schwenkteil des Schwenkgelenks 6 verbunden und dient zur Gewichtsentlastung des oberen Klappenteils 2 und damit zum Erleichtern seiner manuellen Betätigung. Statt der Gasdruckfeder 7 oder ergänzend hierzu kann auch eine An- triebseinrichtung zum motorischen Verschwenken des oberen Klappenteils 2 vorgesehen sein.A motor vehicle having a rear opening (not shown in the figures), for example a station wagon or an SUV (sport utility vehicle), contains a tailgate 1 for closing the rear opening. The tailgate 1 is divided into an upper flap part 2 and a lower flap part 3. The upper flap part 2 is pivotally mounted on the body or the rear of the vehicle about a transverse pivot axis 5 by means of a bearing device arranged adjacent to its upper edge 4, so that it is between a closed position (FIGS. 1 and 2) and an open position (FIGS. 3 and 4 ) is pivotable. The storage device for the upper flap part 2 contains on both sides a hinge or swivel joint 6, which on the body on the vehicle roof z. B. in the area of the roof side member or at the top of the D-pillar. A gas pressure spring 7 arranged in each of the right and left roof side rails is connected to the upper flap part 2 or to a swivel part of the swivel joint 6 connected to the upper flap part 2 and serves to relieve the weight of the upper flap part 2 and thus to facilitate its manual operation. Instead of the gas pressure spring 7 or in addition thereto, an attachment Drive device for motorized pivoting of the upper flap part 2 may be provided.
Das untere Klappenteil 3 ist am Fahrzeugheck mittels einer Lagereinrichtung be- wegbar gelagert, die beidseits jeweils eine Viergelenkanordnung mit einem ersten Schwenkhebel 8 und einem zweiten Schwenkhebel 9 aufweist (siehe insbesondere Fig. 4 und 5), die einerseits karosserieseitig um die Schwenkachsen 10 bzw. 11 angelenkt sind, z. B. an einem an der D-Säule 12 (die in den Fig. 5a bis 5c nur schematisch mit unterbrochener Linie dargestellt ist) befestigten Trägerteil 13. Der erste Schwenkhebel 8 ist andererseits seitlich am unteren Klappenteil 3 mittels eines in der Nähe des Oberrandes 14 des unteren Klappenteils 3 fest angebrachten und eine Schwenkachse festlegenden Schwenkgelenks 15 schwenkbar angelenkt, während der zweite Schwenkhebel 9 am unteren Klappenteil 3 mittels eines eine Schwenkachse festlegenden Schwenkgelenks 16 verschwenkbar ge- lagert ist, das an einer am Seitenrand des unteren Klappenteils 3 fest angebrachten Längsführung 17 verschiebbar gelagert ist und sich beim Verschieben an der Längsführung 17 dem am unteren Klappenteil 3 ortsfesten ersten Schwenkgelenk 15 annähert oder von diesem entfernt. Die Längsführung 17 ist beispielsweise ein Stab, der an seinen beiden Enden mittels einer oberen Halterung 17' bzw. einer unteren Halterung 17" an dem unteren Klappenteil 3 befestigt ist und an dem eine Hülse 18 verschiebbar gelagert ist, an der der zweite Schwenkhebel 9 mittels des Schwenkgelenks 16 gelagert ist.The lower flap part 3 is movably mounted on the rear of the vehicle by means of a bearing device which has a four-bar arrangement on each side with a first pivot lever 8 and a second pivot lever 9 (see in particular FIGS. 4 and 5), which on the one hand on the body side about the pivot axes 10 or 11 are hinged, for. B. on a D-pillar 12 (which is only shown schematically in FIGS. 5a to 5c with a broken line) is attached to the support part 13. The first pivot lever 8 is on the other hand laterally on the lower flap part 3 by means of a near the upper edge 14th of the lower flap part 3 and a swivel joint 15 which fixes a swivel axis, while the second swivel lever 9 is pivotably mounted on the lower flap part 3 by means of a swivel joint 16 which fixes a swivel axis and which is attached to a longitudinal guide 17 fixedly attached to the side edge of the lower flap part 3 is displaceably mounted and approaches or moves away from the first swivel joint 15, which is stationary on the lower flap part 3, when the longitudinal guide 17 is moved. The longitudinal guide 17 is, for example, a rod which is attached at its two ends to the lower flap part 3 by means of an upper holder 17 ′ or a lower holder 17 ″ and on which a sleeve 18 is slidably mounted, on which the second pivot lever 9 is attached of the swivel joint 16 is mounted.
Die beiden Schwenkhebel 8 und 9 sind mittels eines Koppelhebels 19 miteinan- der verbunden, der am ersten Schwenkhebel 8 mittels eines Gelenks 20 und am zweiten Schwenkhebel 9 mittels eines Gelenks 21 gelagert ist, wobei die Gelenke 20 und 21 jeweils z. B. in einem Mittelabschnitt jedes Schwenkhebels 8 bzw. 9 angeordnet sind. Die beiden Schwenkhebel 8 und 9 bilden mit dem Koppelhebel 19 somit ein Viergelenk.The two swivel levers 8 and 9 are connected to one another by means of a coupling lever 19 which is mounted on the first swivel lever 8 by means of a joint 20 and on the second swivel lever 9 by means of a joint 21, the joints 20 and 21 in each case, for. B. are arranged in a central portion of each pivot lever 8 or 9. The two pivot levers 8 and 9 thus form a four-bar linkage with the coupling lever 19.
Eine Einrichtung zum Unterstützen des Verschwenkens der Heckklappe 1 enthält (siehe Fig. 1 bis 5) eine Teleskopeinheit mit zwei mittels einer Kulissenführung aneinander geführten und gegeneinander längs verschiebbaren Schienen 22 und 23, von denen die untere Schiene 23 an ihrem Unterende mittels eines Gelenks 24 karosserieseitig schwenkbar gelagert ist und die obere Schiene 22 mit ihrem Oberende an einem Fortsatz 25 des ersten Schwenkhebels 8, der sich über die Schwenkachse 10 hinaus erstreckt, mittels eines Gelenks 26 angelenkt ist. Eine längs neben der Teleskopeinheit angeordnete Gasdruckfeder 27 ist mit ihrem Oberende an einem karosserieseitigen Lager 28 angelenkt und mit ihrem unterseitig ausfahrenden Kolben 29 mit der oberen Schiene 22 in einem Gelenk 30 direkt oder mittels eines Zugseils verbunden, das zwischen dem Kolben 29 und beispielsweise dem Gelenk 26 gespannt ist.A device for supporting the pivoting of the tailgate 1 contains (see FIGS. 1 to 5) a telescopic unit with two rails 22 and which are guided against one another by means of a link guide and are longitudinally displaceable relative to one another 23, of which the lower rail 23 is pivotally mounted on the body end at its lower end by means of a joint 24 and the upper rail 22 is articulated with its upper end to an extension 25 of the first pivot lever 8, which extends beyond the pivot axis 10, by means of a joint 26 is. A gas pressure spring 27 arranged longitudinally next to the telescopic unit is articulated at its upper end to a body-side bearing 28 and is connected with its lower piston 29 to the upper rail 22 in a joint 30 directly or by means of a traction cable which is connected between the piston 29 and the joint, for example 26 is excited.
Bei geschlossener Heckklappe 1 (siehe Fig. 1 , 2 und 5a) sind die beiden Schienen 22 und 23 der Teleskopeinheit für das untere Klappenteil 3 ausgefahren, während der Kolben 29 der Gasdruckfeder 27 eingefahren ist. Beim Öffnen der Heckklappe 1 wird zunächst das obere Klappenteil 2 entriegelt und um seine Querschwenkachse 5 hochgeschwenkt. Anschließend wird das untere Klappenteil 3 entriegelt und manuell nach oben geschwenkt, wobei die beiden Schwenkhebel 8 und 9 das Klappenteil 3 anheben und dabei nach oben verschwenken. Der Koppelhebel 19 verschwenkt hierbei den zweiten Schwenkhebel 9 relativ zum ersten Schwenkhebel 8 derart, daß die mit dem zweiten Schwenkhebel 9 verbun- dene Hülse 18 aus ihrer Stellung an der unteren Halterung 17" der Längsführung 17 gegen die obere Halterung 17' verschoben wird. Dies hat bei einer entsprechenden Auslegung der beiden Schwenkhebel 8 und 9 zur Folge, daß die Längsführung 17 und damit das untere Klappenteil 3 um das Schwenkgelenk 15 weiter verschwenkt wird (in den Fig. 5a bis 5c im Gegenuhrzeigersinn) im Vergleich mit einer reinen Viergelenklagerung, bei der der Abstand zwischen den beiden Schwenkgelenken 15 und 16 konstant ist.When the tailgate 1 is closed (see FIGS. 1, 2 and 5a), the two rails 22 and 23 of the telescopic unit for the lower flap part 3 are extended, while the piston 29 of the gas pressure spring 27 is retracted. When the tailgate 1 is opened, the upper flap part 2 is first unlocked and pivoted up about its transverse pivot axis 5. Subsequently, the lower flap part 3 is unlocked and pivoted upwards manually, the two pivot levers 8 and 9 lifting the flap part 3 and thereby pivoting upwards. The coupling lever 19 pivots the second pivot lever 9 relative to the first pivot lever 8 such that the sleeve 18 connected to the second pivot lever 9 is displaced from its position on the lower holder 17 ″ of the longitudinal guide 17 against the upper holder 17 ′ has a corresponding design of the two pivot levers 8 and 9 that the longitudinal guide 17 and thus the lower flap part 3 is pivoted further about the pivot joint 15 (in the Fig. 5a to 5c counterclockwise) in comparison with a pure four-pivot bearing, at the distance between the two swivel joints 15 and 16 is constant.
Die Lagerung des unteren Klappenteils 3 ist derart ausgelegt, daß es in seiner Offenstellung (Fig. 3, 4 und 5c) in etwa parallel unter dem oberen Klappenteil 2 und nahe an diesem angeordnet ist. Damit ermöglicht die Lagerung einen großen Öffnungswinkel des unteren Klappenteils 3, dessen unterer Rand sehr weit nach oben geschwenkt wird, so daß der Zutritt zur Hecköffnung des Fahrzeugs weniger stark eingeschränkt ist. Statt der kraftunterstützend wirkenden Gasdruckfeder 27 kann auch eine elektrisch, pneumatisch oder hydraulisch wirkende Antriebseinheit, z. B. ein Hydraulikzylinder, vorgesehen sein, so daß das untere Klappenteil 3 mittels der Antriebseinrichtung verschwenkbar ist. Diese Antriebseinheit kann mit einer Steuerung verbunden sein und gemeinsam mit einer Antriebseinrichtung für das obere Klappenteil 2 betätigt werden, so daß nach einem anfänglichen Hochschwenken des oberen Klappenteils 2 beide Klappenteile synchron in ihre Offenstellungen verschwenkt werden.The storage of the lower flap part 3 is designed such that in its open position (FIGS. 3, 4 and 5c) it is arranged approximately parallel under the upper flap part 2 and close to it. The storage thus enables a large opening angle of the lower flap part 3, the lower edge of which is pivoted very far upward, so that access to the rear opening of the vehicle is less restricted. Instead of the force-supporting gas pressure spring 27, an electrically, pneumatically or hydraulically acting drive unit, for. B. a hydraulic cylinder may be provided so that the lower flap part 3 can be pivoted by means of the drive device. This drive unit can be connected to a controller and operated together with a drive device for the upper flap part 2, so that after an initial swiveling of the upper flap part 2, both flap parts are pivoted synchronously into their open positions.
Die Antriebseinrichtung kann einen Einklemmschutz aufweisen, der z. B. über eine Momentenerkennung eines Antriebsmotors realisiert werden kann. Durch die Steuerung können auch Teilöffnungen der beiden Klappenteile 2 und 3 eingestellt werden. Bei einem motorischen Antrieb der Heckklappe 1 kann mittels eines am Fahrzeugheck oder der Heckklappe angeordneten Sensors eine Hinderniserkennung realisiert werden, so daß eine Kollision der zu öffnenden Heckklappe 1 mit einem Hindernis vermieden werden kann.The drive device can have an anti-trap device which, for. B. can be realized via a torque detection of a drive motor. Partial openings of the two flap parts 2 and 3 can also be set by the control. When the tailgate 1 is driven by a motor, an obstacle detection can be implemented by means of a sensor arranged on the rear of the vehicle or the tailgate, so that a collision of the tailgate 1 to be opened with an obstacle can be avoided.
In alternativer Gestaltung (siehe Fig. 6a bis 6c) ist zum Unterstützen der manuel- len Betätigung jeweils eine Gasdruckfeder 31 vorgesehen, die im seitlichen hinteren Dachbereich längs ausgerichtet ist und sich zwischen dem Gelenk 26 am Fortsatz 25 des ersten Schwenkhebels 8 und einer karosseriefesten Anlenkung 32 erstreckt. Beim Öffnen des unteren Klappenteils 3 fährt der vorgespannte Kolben der Gasdruckfeder 31 aus und übernimmt den wesentlichen Anteil der erfor- derlichen Hubkraft zum Hochschwenken des unteren Klappenteils 3. Durch die Anordnung der Gasdruckfeder 31 im Dachbereich wird in der D-Säule 12 entgegen dem ersten Ausführungsbeispiel kein Bauraum für die Gasdruckfeder 27 bzw. die Schwenkeinrichtung benötigt.In an alternative embodiment (see FIGS. 6a to 6c), a gas pressure spring 31 is provided to support the manual actuation, which is longitudinally aligned in the lateral rear roof area and is located between the joint 26 on the extension 25 of the first pivot lever 8 and a linkage fixed to the body 32 extends. When the lower flap part 3 is opened, the prestressed piston of the gas pressure spring 31 extends and takes over the essential part of the lifting force required to swing the lower flap part 3 upward. The arrangement of the gas pressure spring 31 in the roof area makes the D-pillar 12 contrary to the first exemplary embodiment no space required for the gas pressure spring 27 or the swivel device.
Gemäß einer weiteren alternativen Gestaltung (siehe Fig. 7a bis 7c) ist zur Unterstützung der Verschwenkung des unteren Klappenteils 3 aus seiner Schließstellung jeweils eine Gaszugfeder 33 vorgesehen, die in der D-Säule 12 zwischen einem unteren karosserieseitigen Lager 34 und dem Gelenk 26 am Fortsatz 25 des ersten Schwenkhebels 8 angeordnet ist. Bei geschlossenem unterem Klappenteil 3 (Fig. 7a) ist der ausgefahrene Kolben 35 der Gaszugfeder 32 vorgespannt, um die Hubbewegung des unteren Klappenteils 3 zu unterstützen. Das Verschwenken der Heckklappe 1 erfolgt ansonsten entsprechend den voranste- henden Beispiele.According to a further alternative design (see FIGS. 7a to 7c), a gas tension spring 33 is provided to support the pivoting of the lower flap part 3 from its closed position, which is located in the D-pillar 12 between a lower body-side bearing 34 and the joint 26 on the extension 25 of the first pivot lever 8 is arranged. When the lower flap part 3 is closed (FIG. 7 a), the extended piston 35 of the gas tension spring 32 is prestressed in order to support the lifting movement of the lower flap part 3. The pivoting of the tailgate 1 is otherwise carried out in accordance with the preceding examples.
Das untere Klappenteil 3 kann mit dem oberen Klappenteil 2 mittels einer Koppeleinrichtung, z.B. eines Bowdenzugs, derart gekoppelt sein, daß über das Verschwenken des einen Klappenteils auch das andere Klappenteil verschwenkt wird. So kann ein motorisch bewirktes Verschwenken des oberen Klappenteils 2 auch das untere Klappenteil 3 bzw. ein manuelles Verschwenken des unteren Klappenteils 3 auch das obere Klappenteil 2 synchron verschwenken. Dabei ist eine Einrichtung vorgesehen, damitThe lower flap part 3 can be connected to the upper flap part 2 by means of a coupling device, e.g. a Bowden cable, coupled in such a way that the other flap part is also pivoted by pivoting the one flap part. Thus, a motor-driven pivoting of the upper flap part 2 can also pivot the lower flap part 3 or a manual pivoting of the lower flap part 3 also the upper flap part 2 synchronously. A device is provided so that
Das obere Klappenteil 2 enthält eine Scheibe, die mit einem Rahmen umspritzt ist, oder es enthält einen Rahmen, mit dem die Scheibe verklebt ist. Durch die Aufteilung der Heckklappe in ein oberes Klappenteil und ein unteres Klappenteil weist jedes Klappenteil ein geringeres Gewicht auf, da sie im Gegensatz zu einer gesamten einstückigen Heckklappe, die hohe Verschwenkkräfte aufgrund einer festeren Struktur und damit höheren Gewichts aufweist, mit einer leichterenThe upper flap part 2 contains a pane which is encapsulated with a frame, or it contains a frame to which the pane is glued. Due to the division of the tailgate into an upper flap part and a lower flap part, each flap part is lighter in weight, because in contrast to an entire one-piece tailgate, which has high pivoting forces due to a firmer structure and thus higher weight, it is lighter

B. die EP 0 995 667 B1 , die DE 29 34 430 A1 und die DE 100 33 232 C2).Structure can be built. The lower flap part can e.g. B. in lightweight construction (LFI, PHC, WHC, SMC or LFT) (see, for example, EP 0 995 667 B1, DE 29 34 430 A1 and DE 100 33 232 C2).
Statt einer mechanischen Kopplung der beiden Klappenteile kann eine elektronisch gesteuerte Antriebseinrichtung vorgesehen sein, die z. B. wahlweise nur das obere Klappenteil oder das obere und das untere Klappenteil öffnet. Bei entsprechender Gestaltung der beiden Klappenteile an ihrer Nahtstelle kann auch nur das untere Klappenteile bei geschlossenem oberen Klappenteil über dieses geschwenkt werden. BezugszeichenlisteInstead of a mechanical coupling of the two flap parts, an electronically controlled drive device can be provided, which, for. B. either only the upper flap part or the upper and lower flap part opens. With a corresponding design of the two flap parts at their interface, only the lower flap parts can be pivoted over them when the upper flap part is closed. LIST OF REFERENCE NUMBERS
