Description
Die Erfindung bezieht sich auf eine Heckklappenanlenkung für Kraftfahrzeuge mit einer einen im wesentlichen den gesamten Bereich der Heckfläche eines als Kombifahrzeug ausgebildeten Kraftfahrzeuges übergreifenden heckseitigen Karosserieausschnitt freigebenden bzw. verschließenden, oberendig um eine quer zur Fahrtrichtung gerichtete Schwenkachse nach oben offenbar am Dach eines Kraftfahrzeuges angelenkten Heckklappe, wobei die Heckklappe vermittels wenigstens eines aus einer feststehenden und einer beweglichen Gelenkhälfte bestehenden Schwenkgelenkes um eine zum Öffnungsrand des heckseitigen Karosserieausschnittes parallele Achse schwenkbar am Fahrzeugdach angelenkt ist und mindestens über einen gewissen Öffnungswinkel hin durch eine vorspannbare Federlast in Öffnungsrichtung beaufschlagt oder wenigstens gewichtskompensiert ist.The invention relates to a tailgate linkage for motor vehicles with a substantially the entire area of the rear surface as a Combined vehicle trained motor vehicle overlapping rear body cutout releasing or closing, on the top around a cross to the direction of travel upward pivot axis apparently on the roof of one Motor vehicle hinged tailgate, the tailgate by means of at least one consisting of a fixed and a movable half of the joint Swivel joint around a to the opening edge of the rear body cutout parallel axis is pivotally hinged to the vehicle roof and at least over a certain opening angle by a pretensionable Spring load applied in the opening direction or at least weight compensated is.
Im Zuge der Konzipierung moderner Kombifahrzeuge mit immer tiefer werdenden
Laderaum ist ein ungehinderter und bequemer Zugang auch zu den innersten
Bereichen des Laderaumes nur dann möglich bzw. erreichbar, wenn die
Heckklappe soweit nach oben verschwenkt werden kann, daß sich der Fahrzeugbenutzer
nicht mehr zu bücken braucht um unmittelbar an die Heckwand des
Fahrzeuges heranzutreten. Dies kann in einfachster Weise dadurch erreicht
werden, daß der maximale Öffnungswinkel der Heckklappe derart vergrößert
wird, daß auch große Personen noch völlig ungehindert, d.h. aufrechtstehend bis
unmittelbar an die Heckwand des Fahrzeuges herantreten können.
Eine derartige Vergrößerung des Öffnungswinkels einer Heckklappe bietet in
konstruktiver Hinsicht keine besonderen Schwierigkeiten. In the course of the design of modern station wagons with ever deeper loading space, unhindered and convenient access to the innermost areas of the loading space is only possible or accessible if the tailgate can be swung upwards so that the vehicle user no longer has to bend down to go directly to the rear wall of the vehicle. This can be achieved in a very simple manner in that the maximum opening angle of the tailgate is increased in such a way that even tall people can still approach the rear wall of the vehicle completely unimpeded, ie upright.
Such an enlargement of the opening angle of a tailgate does not pose any particular difficulties from a design point of view.
Auf der anderen Seite sind aber in der völligen Öffnungslage sehr steil nach
oben ausgestellte Heckklappen für kleinere Personen nur mit Mühe wieder zu
schließen.
Zudem ist sehr häufig durch die lichte Höhe von Garagen oder Ähnlichem eine
Grenze für den maximalen Öffnungswinkel der Heckklappen gezogen, da ein
unbeabsichtigtes Anschlagen der Heckklappe an der Garagendecke zu Beschädigungen
wenigstens der Heckklappe führen kann und daher jedenfalls soweit als
möglich vermieden werden soll. Zwar sind zu diesem Zweck bereits längenverstellbare
Stützen bekannt, welche teleskopisch verlängerbar und in der jeweils
eingestellten Länge verriegelbar sind, jedoch erfordern solche Hilfsanordnungen
zum einen einen beträchtlichen zusätzlichen Aufwand und zum anderen eine
besondere Aufmerksamkeit des Fahrzeugbenutzers. Im Zusammenhang mit der
Anlenkung von Kofferraumdeckeln bei mit einem Stufenheck ausgestatteten
Fahrzeugkarosserien ist aus der DE-PS 936 794 eine Feststelleinrichtung bekannt,
bei welcher die Feststellung des Kofferraumdeckels unter Verwendung
einer ohnehin vorhandenen Gewichtsenlastungsfeder in der Weise bewerkstelligt
wird, daß die Gewichtsenlastungsfeder bei in seiner voll geöffneten Stellung befindlichem
Kofferraumdeckel mit einer Abwinkelung des Scharnierarmes formschlüssig
verrastet. Eine solche Ausbildung einer Feststelleinrichtung schließt
ein Feststellen des Kofferraumdeckels in einer nicht voll geöffneten Stellung ausund
läßt sich vor allem nicht bei Heckklappen von Kombifahrzeugen verwenden.
Gleichfalls nicht für die Anwendung bei Heckklappen von Kombifahrzeugen geeignet
sind die bekannten Einrichtungen zum Feststellen von Seitentüren von
Fahrzeugen etwa nach US-PS 2 841 815 oder US-PS 3 213 485, da derartige
Feststelleinrichtungen eine Feststellung der Türe lediglich in deren voll geöffneter
Stellung ermöglichen und darüberhinaus ihrer Bauart nach einen maximalen
Türöffnungswinkel von lediglich etwa 75° zulassen. On the other hand, when the hatchbacks are fully open, the tailgates flipped upwards are very difficult for smaller people to close again.
In addition, the clear height of garages or the like very often draws a limit for the maximum opening angle of the tailgates, since an unintentional striking of the tailgate on the garage ceiling can damage at least the tailgate and should therefore be avoided as far as possible. Although length-adjustable supports are already known for this purpose, which are telescopically extendable and lockable in the length set in each case, such auxiliary arrangements on the one hand require considerable additional effort and on the other hand require special attention from the vehicle user. In connection with the articulation of trunk lids in vehicle bodies equipped with a notchback, a locking device is known from DE-PS 936 794, in which the locking of the trunk lid is accomplished using an already existing weight load spring in such a way that the weight load spring is in its full in the open position of the trunk lid with an angled locking of the hinge arm. Such a design of a locking device precludes locking of the trunk lid in a position that is not fully open and, above all, cannot be used with hatchbacks of combination vehicles.
Likewise not suitable for use in hatchbacks of combi vehicles are the known devices for locking side doors of vehicles, for example according to US Pat. No. 2,841,815 or US Pat. No. 3,213,485, since such locking devices only allow the door to be locked in its fully open position and also allow a maximum door opening angle of only about 75 ° due to their design.
Der Erfindung liegt daher die Aufgabe zugrunde eine Heckklappenanlenkung für eine um einen großen Öffnungswinkel nach oben ausstellbare Heckklappe zu schaffen, welche ein Anhalten bzw. Feststellen der Heckklappe in wenigstens einer Teilöffnungslage ermöglicht und insbesondere ein unbeabsichtigtes Anschlagen der Heckklappe an einer Garagendecke oder dergl. ausschließt und welche darüber hinaus ohne großen Aufwand und insbesondere ohne das Erfordernis den bei bestehenden Karosseriekonstruktionen vorgesehenen Einbauraum für die Heckklappenanlenkung zu vergrößern auch in Verbindung mit gebräuchlichen Bauarten von Heckklappenanlenkungen anwendbar ist.The invention is therefore based on the object of a tailgate linkage for a tailgate that can be opened upwards by a large opening angle create a stopping or locking the tailgate in at least a partial opening position and in particular an unintentional striking excludes the tailgate on a garage ceiling or the like and which moreover without much effort and in particular without the requirement the installation space provided in existing body constructions for the tailgate linkage to enlarge also in connection with common Types of tailgate linkages is applicable.
Diese Aufgabe wird erfindungsgemäß im wesentlichen dadurch gelöst, daß mit
wenigstens einem der Schwenkgelenke der Heckklappenanlenkung eine durch
eine Rastierung gebildete Haltevorrichtung zum Halten der Heckklappe in mindestens
einer vorgegebenen Teilöffnungslage baulich vereinigt ist, wobei die Rastierung
der Haltevorrichtung aus einem an der feststehenden Schwenkgelenkhälfte
abgestützten, federbelasteten Rastglied und wenigstens einer diesem zugeordneten
an mindestens einer Seitenfläche der beweglichen Schwenkgelenkhälfte
angeordneten bzw. ausgebildeten Rastmarke besteht.
Die erfindungsgemäße Haltevorrichtung zeichnet sich zunächst durch einen verhältnismäßig
geringen Herstellungs-und Montageaufwand aus und gewährleistet
zugleich in Verbindung mit einer dieser zugeordneten Gewichtsentlastung
eine sichere Feststellung der Heckklappe in wenigstens einer Teilöffnungslage,
wobei an die Rastkraft der Haltevorrichtung verhältnismäßig geringe Anforderungen
gestellt werden, da in diesem Falle keine größeren Kräfte auf die Heckklappe
wirken, insbesondere dann, wenn die Gewichtsentlastung, sei es eine mechanische
Feder, beispielsweise eine Drehstabfeder oder sei es eine Gasfeder direkt
an der beweglichen Schwenkgelenkhälfte des Heckklappenschwenkgelenkes
angreift. Besonders vorteilhaft ist dabei neben dem geringen Raumbedarf der
Halteeinrichtung insbesondere auch die komfortable Handhabung der Heckklappe
durch den Fahrzeugbenutzer. Die erfindungsgemäße Haltevorrichtung
gewährleistet aber auch in Verbindung mit einer dem Antrieb der Heckklappe in
Öffnungsrichtung zugeordneten Gasdrückfeder oder dergl. ein sicheres Feststellen
der Heckklappe in wenigstens einer ausgewählten Öffnungslage, da die Rastierung
ohne besonderen Aufwand hinreichend stark ausgebildet werden kann.
Insbesondere bei solcherart in Öffnungsrichtung angetriebenen Heckklappen,
die sich nach dem Öffnen des Schlosses selbsttätig in Öffnungsrichtung bewegen,
hat die erfindungsgemäße Haltevorrichtung den Vorteil, daß ein Anschlagen der
Heckklappe an einer Garagendecke oder dergl. ausgeschlossen ist. Die erfindungsgemäße
Haltevorrichtung bringt schließlich auch noch den Vorteil mit sich,
daß die Haltevorrichtung im Wesentlichen innerhalb des der Heckklappenanlenkung
dienenden Schwenkgelenkes untergebracht und zugleich auch zusammen
mit diesen als vorgefertigte Baueinheit am Fahrzeug montiert werden kann. This object is essentially achieved in that at least one of the swivel joints of the tailgate linkage structurally combines a holding device formed by a detent for holding the tailgate in at least one predetermined partial opening position, the detenting of the holding device consisting of a spring-loaded spring-loaded support on the fixed swivel joint half Detent member and at least one associated with this arranged or formed on at least one side surface of the movable swivel half detent mark.
The holding device according to the invention is initially characterized by a relatively low manufacturing and assembly effort and, at the same time, in conjunction with a weight relief associated with it, ensures that the tailgate is securely fixed in at least one partial opening position, with relatively low demands being placed on the latching force of the holding device, since in this If no greater forces act on the tailgate, in particular when the weight relief, be it a mechanical spring, for example a torsion bar spring, or a gas spring acts directly on the movable swivel joint half of the tailgate swivel joint. In addition to the small space requirement of the holding device, the comfortable handling of the tailgate by the vehicle user is particularly advantageous. However, the holding device according to the invention also ensures, in conjunction with a gas pressure spring or the like associated with the drive of the tailgate in the opening direction, that the tailgate is securely locked in at least one selected opening position, since the catch can be made sufficiently strong without any special effort. Particularly in the case of tailgates which are driven in the opening direction and move automatically in the opening direction after the lock has been opened, the holding device according to the invention has the advantage that the tailgate cannot strike a garage ceiling or the like. Finally, the holding device according to the invention also has the advantage that the holding device can be accommodated essentially within the swivel joint serving for tailgate articulation and, at the same time, can also be mounted together with these as a prefabricated structural unit on the vehicle.
