Abstract
Description
Die Erfindung betrifft einen Scharniermechanismus zum Öffnen einer Motorhaube, mit mehreren Hebeln, wobei die Motorhaube durch Überführen des Scharniermechanismus aus einer Normalstellung in eine Öffnungsstellung geöffnet werden kann.The The invention relates to a hinge mechanism for opening a Bonnet, with multiple levers, the bonnet by transferring the hinge mechanism be opened from a normal position to an open position can.
Um bei einem Kraftfahrzeug mit einem derartigen Scharnier eine zusätzliche Schutzfunktion für Fußgänger zu schaffen, bei der die Motorhaube zur Bereitstellung von zusätzlichem Deformationsraum angehoben wird, maßte bisher das Scharnier entkoppelt und wenigstens ein zusätzliches Gelenk vorgesehen werden. Zudem sind bestimmte Arten von Vorrichtungen zum Anheben der Motorhaube (z.B. pyrotechnische) auch bei einer Fehlauslösung grundsätzlich nur einmal verwendbar, oder sie können nur werkstattseitig mit nicht unerheblichem Aufwand wieder einsatzfähig gemacht werden. Schließlich ist die Funktion solcher sicherheitsrelevanter Vorrichtungen auch bei langem Nichtgebrauch sicherzustellen, was unter Umständen eine regelmäßige Funktionsüberprüfung erfordert.Around in a motor vehicle with such a hinge an additional Protective function for pedestrians too create in which the bonnet to provide additional Deformation space is raised, so far measured the hinge decoupled and at least one extra Be provided joint. There are also certain types of devices for lifting the hood (for example, pyrotechnic) even in a false triggering in principle only usable once, or they can only be with the workshop not inconsiderable effort to be made operational again. Finally is the function of such safety-relevant devices also at to ensure long disuse, which may be a regular functional check required.
Aufgabe der Erfindung ist es, einen mit geringem Aufwand realisierbaren Mechanismus zum Anheben einer Motorhaube zu schaffen, der einfach zu handhaben ist, aber dennoch alle sicherheitsrelevanten Anforderungen erfüllt.task The invention is a realizable with little effort Mechanism for lifting a bonnet to create that easy to handle, but still all safety-related requirements Fulfills.
Zur Lösung dieser Aufgabe wird vorgeschlagen, einen Scharniermechanismus der eingangs genannten Art so weiterzubilden, daß er einen Kraftspeicher und ein Auslöseelement umfaßt, wobei nach einer Betätigung des Auslöseelements der Scharniermechanismus mit Hilfe des Kraftspeichers aus der Normalstellung unmittelbar in eine Anhebestellung überführt wird, in der die Motorhaube eine angehobene Position zum Schutz eines Fußgängers einnimmt. Grundidee der Erfindung ist es, den Fußgänger-Schutzmechanismus in den Scharniermechanismus zum normalen Öffnen der Motorhaube zu integrieren. Die Kraft zum Anheben der Motorhaube liefert der Kraftspeicher, der auch für den normalen Öffnungsvorgang der Haube benutzt werden kann. Durch die besondere Auslegung des Scharniermechanismus kann auf zusätzliche Bauteile größtenteils verzichtet werden. Ein weiterer wesentlicher Vorteil des erfindungsgemäßen Scharniermechanismus besteht darin, daß die bei einem drohenden Unfall erforderlichen Bauteile zum Anheben der Motorhaube bei jedem normalen Öffnen und Schließen der Motorhaube mitbewegt werden, so daß die Gefahr eines Verklemmens oder Festsitzens erheblich verringert ist. Eine Funktionsüberprüfung kann durch Öffnen der Haube auf einfache Weise vorgenommen werden.to solution This object is proposed, a hinge mechanism of educate the type mentioned above so that he has a power storage and a trigger element comprises being after an actuation of the trigger element the hinge mechanism with the help of the energy storage from the normal position is transferred directly to a lifting position, in which the hood occupies a raised position to protect a pedestrian. Basic idea of Invention is the pedestrian protection mechanism to integrate into the hinge mechanism for normal opening of the bonnet. The power to lift the hood provides the energy storage, which also for the normal opening process the hood can be used. Due to the special design of the Hinge mechanism can largely dispense with additional components become. Another significant advantage of the hinge mechanism according to the invention is that the in case of imminent accident required components for lifting the Bonnet at every normal opening and closing the hood can be moved, so that the risk of jamming or stuck is significantly reduced. A functional check can by opening the hood can be made easily.
Der Kraftspeicher umfaßt vorzugsweise ein Federelement, insbesondere eine Spiralfeder, die die notwendige Kraft zum Anheben der Motorhaube ohne Verzögerung zur Verfügung stellen kann und reversibel einsetzbar ist.Of the Force store includes preferably a spring element, in particular a spiral spring, the the necessary force for lifting the bonnet without delay to disposal can make and reversible use.
Eine Weiterbildung der Erfindung sieht vor, daß der Scharniermechanismus in eine Spannstellung gebracht werden kann, aus der er durch eine Bewegung der Motorhaube unter gleichzeitigem Spannen des Federelements zurück in die Normalstellung gebracht werden kann. Eine solche Ausgestaltung des Scharniermechanismus, die die Reversibilität der Fußgänger-Schutzvorrichtung gewährleistet, erweist sich als besonders vorteilhaft, weil der Scharniermechanismus nach einer möglichen Fehlauslösung ohne besonderen Aufwand vom Fahrer selbst für einen weiteren Einsatz vorbereitet werden kann.A Further development of the invention provides that the hinge mechanism can be brought into a cocking position, from which he moves through the hood with simultaneous tensioning of the spring element back into the Normal position can be brought. Such an embodiment of Hinge mechanism that ensures the reversibility of the pedestrian protection device proves to be particularly advantageous because of the hinge mechanism after a possible false triggering prepared by the driver himself for further use without special effort can be.
Gemäß einer bevorzugten Ausführungsform der Erfindung umfaßt der Scharniermechanismus wenigstens vier Hebel und vier Gelenke, wobei
- – ein an den Kraftspeicher gekoppelter erster Hebel an einem fahrzeugfesten ersten Gelenk gelagert ist,
- – ein an die Motorhaube gekoppelter zweiter Hebel über ein zweites Gelenk an den ersten Hebel gekoppelt ist,
- – ein dritter Hebel über ein drittes Gelenk an den ersten Hebel gekoppelt ist, und
- – ein ebenfalls an die Motorhaube gekoppelter vierter Hebel über ein viertes Gelenk an den dritten Hebel gekoppelt ist.
- A first lever, which is coupled to the energy store, is mounted on a vehicle-fixed first joint,
- A second lever coupled to the engine hood is coupled to the first lever via a second joint,
- A third lever is coupled to the first lever via a third joint, and
- - A likewise coupled to the hood fourth lever is coupled via a fourth joint to the third lever.
Damit der Scharniermechanismus nach dem „Aufladen" des Kraftspeichers (Spannen der Spiralfeder) unter normalen Umständen in der Normalstellung verharrt und nur in einem Auslösefall aktiviert wird, ist vorgesehen, daß ein am vierten Hebel angeordneter Ansatz in der Normalstellung des Scharniermechanismus durch das Auslöselement in einer fahrzeugfesten Position gehalten und nach Betätigung des Auslöseelements freigegeben wird.In order to the hinge mechanism after "charging" the energy accumulator (tensioning the spiral spring) under normal circumstances remains in the normal position and is activated only in a triggering case, is provided that a on the fourth lever arranged approach in the normal position of the hinge mechanism through the trigger element held in a vehicle-fixed position and after pressing the trigger element is released.
Das Auslöseelement ist vorzugsweise ein um ein fahrzeugfestes fünftes Gelenk umlegbarer Sicherungshebel, der am Ansatz des vierten Hebels angreift.The triggering element is preferably a safety lever which can be folded around a vehicle-fixed fifth joint, which attacks at the base of the fourth lever.
