Abstract

The front engine cover (1) is supported on a pair of hinge arms (4,5) each side at the rear. The bottom ends of the hinge arms are pivoted on a bottom support bracket (10) whose front end is hinged (12) on the vehicle and whose rear end can be raised in a collision. This raises the rear end of the engine cover, while the front end remains held by the catch. The raised setting reduces injury risk for pedestrians. The rear end of each support bracket is raised by a compressed spring or by a pyrolytic charge, released by the collision sensor. The system can be enhanced by sensors which detect pedestrians struck by the vehicle and enable the safety system to be deployed without activation by the normal collision sensors.

Description

Die Erfindung bezieht sich auf eine Anordnung einer Frontklappe an einem Fahr­ zeug nach dem Oberbegriff des Anspruchs 1 sowie auf ein Verfahren zur Verlage­ rung einer Frontklappe nach Anspruch 10.The invention relates to an arrangement of a front flap on a driver according to the preamble of claim 1 and a method for publishers tion of a front flap according to claim 10.

Um bei einer Kollision eines Fußgängers mit einem Kraftfahrzeug das Ausmaß von Verletzungen, insbesondere im Brust- und Kopfbereich, zu minimieren, ist es aus der DE 28 41 315 A1 bekannt, den fahrtrichtungsabgewandten hinteren Bereich der Frontklappe im Fall einer Fußgängerkollision anzuheben. Hierdurch wird ein Abstand der Frontklappe zur steifen Unterstruktur des Fahrzeuges (Motor, Feder­ beinaufnahmen etc.) erreicht, so daß an der Frontklappe ein Deformationsweg zur Verfügung steht. Die genannte Schrift zeigt prinzipielle Möglichkeiten zur Verlage­ rung der Frontklappe auf, ohne anzugeben, wie die Verlagerung bei einer im Be­ reich der Windschutzscheibe scharnierten Frontklappe erfolgen soll.In the event of a collision between a pedestrian and a motor vehicle, the extent of It is over to minimize injuries, especially in the chest and head area known from DE 28 41 315 A1, the rear area facing away from the direction of travel the front flap in the event of a pedestrian collision. This will be a Distance of the front flap to the rigid substructure of the vehicle (engine, spring leg mounts etc.) reached, so that a deformation path to the front flap Available. The font mentioned shows basic possibilities for publishers open the front flap without specifying how the relocation of a richly hinged front flap should take place.

Aufgabe der Erfindung ist es, die bekannte Anordnung weiterzubilden und Möglich­ keiten zur Umsetzung der Frontklappenverlagerung bei einem Fahrzeug aufzuzei­ gen, das eine im Bereich der Windschutzscheibe angelenkte Frontklappe aufweist.The object of the invention is to develop the known arrangement and possible to implement the implementation of the bonnet shift in a vehicle gene, which has a hinged front flap in the area of the windshield.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Anspruch 10 gibt ein Verfahren wieder, das einen vorteilhaften Ablauf der Frontklappenverlagerung beschreibt. This object is solved by the features of claim 1. Claim 10 there a procedure again, which is an advantageous sequence of the bonnet shift describes.  

Kerngedanke gemäß Anspruch 1 ist es, die Scharniereinrichtung selbst anzuhe­ ben. Hierdurch ergibt sich ein besonders einfacher Aufbau ohne die Notwendigkeit einer Entkopplung von Scharniereinheit und Frontklappe. Die fahrzeugvordersei­ tige Verriegelungseinrichtung, mit der die Frontklappe in ihrer geschlossenen Lage an der Karosserie fixiert ist, bildet im Fall einer Fußgängerkollision den vorderen Drehpunkt bzw. die vordere Drehachse, um die die hintere Kante der Frontklappe samt wesentlicher Teile der Scharniereinrichtung verschwenkt wird. Übliche Verrie­ gelungseinrichtungen ermöglichen die hierfür erforderliche Drehbarkeit ohne weite­ res.The main idea according to claim 1 is to raise the hinge device itself ben. This results in a particularly simple structure without the need a decoupling of the hinge unit and the front flap. The vehicle front term locking device with which the front flap in its closed position fixed to the body, forms the front in the event of a pedestrian collision Pivot or the front axis of rotation around which the rear edge of the front flap is pivoted together with essential parts of the hinge device. Usual Verrie control devices enable the required rotatability without any space res.

Der Scharnierträger gemäß Anspruch 2 nimmt die Scharniereinrichtung auf, die praktisch unverändert von einem Fahrzeug mit konventioneller Anordnung der Frontklappe übernommen werden kann. Der Scharnierträger ist gelenkig an einen karosserieseitigen Befestigungsabschnitt angebunden. Im Normalbetrieb des Fahr­ zeugs ist der Scharnierträger gegenüber der Karosserie durch eine Verriegelungs­ einrichtung fixiert, so daß das Gelenk zwischen Scharnierträger und Befestigungs­ abschnitt außer Funktion gesetzt ist. Erst bei Erkennen einer Fußgängerkollision wird die Verriegelung gelöst und der Scharnierträger freigegeben, so daß nunmehr der Scharnierträger und mit ihm die Scharniereinrichtung gegenüber der Karosse­ rie verschwenkbar ist. Das Gelenk zwischen dem Scharnierträger und dem Befe­ stigungsabschnitt weist bevorzugt eine horizontale und quer zur Fahrtrichtung ver­ laufende Drehachse auf, die, in Fahrtrichtung betrachtet, vor der Drehachse des Frontklappenscharniers liegt. Der Abstand der Drehachsen von Scharnierträger und Frontklappenscharnier bestimmt den Radius der Kreisbahn, die der hintere Endabschnitt der Frontklappe bei einer Fußgängerkollision beschreibt (und damit den Verlagerungsweg der Frontklappe in Richtung der Hochachse des Fahrzeugs).The hinge bracket according to claim 2 receives the hinge device, the practically unchanged from a vehicle with a conventional arrangement of Front flap can be taken over. The hinge bracket is articulated to one tied to the body-side fastening section. In normal driving operation Stuff is the hinge bracket against the body by a lock device fixed so that the joint between the hinge bracket and attachment section is disabled. Only when a pedestrian collision is recognized the lock is released and the hinge bracket released, so that now the hinge bracket and with it the hinge device opposite the body rie is pivotable. The hinge between the hinge bracket and the befe Stigungs section preferably has a horizontal and transverse to the direction of travel running axis of rotation, which, viewed in the direction of travel, before the axis of rotation of the Front flap hinge. The distance of the axes of rotation from the hinge bracket and front flap hinge determines the radius of the circular path, that of the rear End section of the front flap in a pedestrian collision describes (and thus the path of the bonnet in the direction of the vertical axis of the vehicle).

Durch die Zwangsführung über den drehbar gelagerten Scharnierträger wird ferner eine sichere Fixierung der Frontklappe an der Karosserie erreicht. Damit kann bei einem stärkeren Aufprall des Fahrzeugs auf ein Hindernis ein Eindringen der Frontklappe in die Windschutzscheibe zuverlässig verhindert werden, während diese Gefahr beispielsweise bei einer Lösung gemäß der DE 28 41 315 A1 be­ steht. Durch die Erfindung wird somit insbesondere die Gefahr einer Zerstörung des etwa zeitgleich sich aufblasenden Airbags für Fahrer und Beifahrer durch eine eindringende Frontklappe stark reduziert. Die erfindungsgemäße Zwangsführung der Frontklappe durch den gelenkig an der Karosserie befestigten Scharnierträger bewirkt bei größeren Längskräften sogar ein Niederdrücken der Frontklappe in ihre Ausgangslage.Due to the positive guidance over the rotatably mounted hinge bracket the front flap is securely attached to the body. So that at a stronger impact of the vehicle against an obstacle Front flap in the windshield can be prevented reliably while this danger, for example, in a solution according to DE 28 41 315 A1 stands. The invention thus particularly reduces the risk of destruction  of the airbag for driver and front passenger inflating at about the same time penetrating front flap greatly reduced. The positive control according to the invention the front flap through the hinge bracket that is articulated to the body even causes the front flap to be pressed down into its with greater longitudinal forces Starting position.

Neben einer Verschwenkung des Scharnierträgers gemäß Anspruch 2 ist für die Verlagerung der Scharniereinrichtung auch die Führung über eine Kulisse möglich (Ansprüche 3 bis 5). Als Kulisse wird im Zusammenhang mit der vorliegenden Er­ findung jede Einrichtung mit ineinandergreifenden Elementen bezeichnet, die eine Verlagerung der Scharniereinrichtung gegenüber der Karosserie entlang einer festgelegten Bahn ermöglicht. Durch die Kulisse kann die Richtung und die Größe der Verlagerung individuell festgelegt werden. Bevorzugt bewirkt die Kulisse eine Verschiebung der Scharniereinrichtung etwa in Richtung der Hochachse des Fahr­ zeugs.In addition to pivoting the hinge bracket according to claim 2 is for the Relocation of the hinge device also allows guidance over a backdrop (Claims 3 to 5). As a backdrop in connection with the present Er find each facility with interlocking elements, the one Relocation of the hinge device relative to the body along one fixed path allows. Through the backdrop, the direction and the size of the relocation can be determined individually. The backdrop preferably effects one Displacement of the hinge device approximately in the direction of the vertical axis of the drive stuff.

Die Verlagerung der Frontklappe kann grundsätzlich durch die Krafteinwirkung des Fußgängers auf die Frontklappe erfolgen, wie beispielsweise in der EP 0 630 801 B1 beschrieben. Bevorzugt wird jedoch gemäß Anspruch 6 eine fremdenergieer­ zeugende Einrichtung verwendet, die an der Unterseite des Scharnierträgers an­ greift und diesen, sobald der Scharnierträger durch eine Sensoreinrichtung, die eine Kollision mit einem Fußgänger erkennt, freigegeben wird, nach oben verla­ gert. Bei einem schwenkbar angelenkten Scharnierträger gemäß Anspruch 2 greift hierbei die fremdkrafterzeugende Einrichtung in einem Abstand zur Drehachse des Scharnierträgers an.The displacement of the front flap can basically be caused by the force of the Pedestrian on the front flap, as for example in EP 0 630 801 B1 described. However, an external energy source is preferred Convincing device used on the underside of the hinge bracket engages and this as soon as the hinge bracket by a sensor device, the recognizes a collision with a pedestrian, is released, move upwards device. With a pivotally hinged hinge bracket according to claim 2 engages here the external force generating device at a distance from the axis of rotation of the Hinge bracket.

Besondere Vorteile ergeben sich, wenn zur Verlagerung der Frontklappe eine me­ chanische Feder, z. B. eine metallische Schraubenfeder, verwendet wird (Anspruch 7). Derartige Federn sind kostengünstig herzustellen, einfach im Aufbau, setzen die gespeicherte Energie innerhalb kurzer Zeit frei und sind auch nach längerem Nichtgebrauch mit hoher Wahrscheinlichkeit noch funktionsfähig. Außerdem kann bei kleineren Kollisionen und bei Fehlauslösungen das System ohne weiteres in seine Ausgangslage zurückgebracht werden, indem die Feder manuell wieder in ihre gespannte Lage gebracht wird. Dieses Spannen kann beispielsweise durch Niederdrücken der hinteren Kante der Frontklappe erfolgen. Alternativ kann die Feder durch einfaches Öffnen der Frontklappe von ihrer Vorderseite aus wieder in ihre gespannte Lage überführt werden.There are special advantages if a me to move the front flap chan spring, e.g. B. a metallic coil spring is used (claim 7). Such springs are inexpensive to manufacture, simple to set up The stored energy is free within a short period of time and is also available after a longer period Not likely to still work when not in use. Besides, can in the event of minor collisions and false triggers, the system easily in its starting position can be brought back by manually putting the spring back in their tense situation is brought. This tensioning can be done, for example  Depress the rear edge of the front flap. Alternatively, the Spring back in by simply opening the front flap from its front their tense situation will be transferred.

Grundsätzlich kann zur Verlagerung der Frontklappe auch eine Gasfeder (Anspruch 8) eingesetzt werden, ebenso wie andere energiespeichernde oder energiefreisetzende Mittel (z. B. pyrotechnische Einrichtungen).Basically, a gas spring can also be used to move the front flap (Claim 8) are used, as well as other energy storage or energy-releasing agents (e.g. pyrotechnic devices).

Die Vorteile der erfindungsgemäßen Lösung gelten in gleicher Weise für Schar­ niereinrichtungen mit einfachen Drehachsen und für die weit verbreiteten Vierge­ lenk-Scharnieranordnungen (Anspruch 9). Hierbei liegt bei einer Verschwenkbar­ keit des Scharnierträgers gemäß Anspruch 2 die Drehachse des Scharnierträgers - in Fahrtrichtung betrachtet - bevorzugt vor den Anlenkpunkten der Gelenkarme des Viergelenks am Scharnierträger.The advantages of the solution according to the invention apply equally to coulters nier facilities with simple axes of rotation and for the widely used Vierge Steering hinge assemblies (claim 9). Here is a swivel speed of the hinge bracket according to claim 2, the axis of rotation of the hinge bracket - viewed in the direction of travel - preferably in front of the articulation points of the articulated arms of the Four-joint on the hinge bracket.

Durch das Verfahren gemäß Anspruch 10 wird sichergestellt, daß die Verlagerung der Frontklappe abgeschlossen ist, bevor der Aufprall des Fußgängers auf die Frontklappe erfolgt. Hierdurch wird verhindert, daß die emporschnellende Front­ klappe dem Fußgänger mit erhöhter Geschwindigkeit entgegenkommt und dadurch das Verletzungsrisiko erhöhen würde. Durch das erfindungsgemäße Verfahren wird sichergestellt, daß zum Zeitpunkt des Fußgängeraufpralls an der Frontklappe bereits der maximale Deformationsweg zur Verfügung steht.The method according to claim 10 ensures that the relocation the front flap is closed before the pedestrian hits the Front flap is done. This prevents the soaring front flap meets the pedestrian at increased speed and thereby would increase the risk of injury. By the method according to the invention it is ensured that at the time of the pedestrian impact on the front flap the maximum deformation path is already available.

Eine Frontklappe 1 eines Kraftfahrzeugs ist über eine in ihrer Gesamtheit mit 2 bezeichnete Scharniereinrichtung an einem Stützträger 3 für einen nicht darge­ stellten Kotflügel gelagert. Die Scharniereinrichtung 2 ist als Viergelenk mit einem vorderen und einem hinteren Gelenkarm 4 bzw. 5 ausgebildet und ermöglicht eine Öffnung der Frontklappe 1 wie in Fig. 2 dargestellt. Die Frontklappe 1 ist hierbei, in Fahrtrichtung FR betrachtet, an ihrem hinteren Endabschnitt im Bereich des so­ genannten Windlaufs des Kraftfahrzeugs angeschlagen und öffnet sich von der Fahrzeugvorderseite her. Die Gelenkarme 4 und 5 sind einerseits über Gelenke 6 und 7 an der Frontklappe 1 und andererseits über Gelenke 8 und 9 an einem Scharnierträger 10 angelenkt. Selbstverständlich kann die Scharniereinrichtung 2 auch von einem andersartig aufgebauten Mehrgelenkscharnier oder einem Einge­ lenkscharnier gebildet werden. Der Scharnierträger 10 bildet quasi die Grundplatte für die Scharniereinrichtung 2. Erfindungsgemäß ist der Scharnierträger 10 an sei­ nem vorderen Endabschnitt über eine Drehachse 11 mit einer Anschraubplatte 12 gelenkig verbunden. Die Anschraubplatte 12 ist ihrerseits über Schrauben 13 fest mit dem Stützträger 3 verschraubt. An seinem hinteren Endabschnitt ist der Scharnierträger 10 über eine Verriegelungseinrichtung 14 mit einem exzentrisch gelagerten Riegel 15 in der in den Fig. 1 und 2 dargestellten Position arretiert. Im Abstand d (siehe Fig. 3) zur Drehachse 11 greift an der Unterseite 16 des Scharnierträgers 10 eine energiespeichernde Einrichtung 17 an. Die energiespei­ chernde Einrichtung 17 besteht im wesentlichen aus einer Schraubenfeder 18, die mit einem innenliegenden Kern 19 in eine topfförmige Aussparung 20 des Stütz­ trägers 3 eingesetzt ist. Am oberen Endabschnitt der Schraubenfeder 18 ist ein Verbindungsstück 21 angeordnet, das ein Gelenk 22 zur Verbindung mit dem Scharnierträger 10 aufweist.A front flap 1 of a motor vehicle is mounted on a hinge device designated in its entirety by 2 on a support bracket 3 for a fender not shown. The hinge device 2 is designed as a four-bar linkage with a front and a rear link arm 4 or 5 and enables the front flap 1 to be opened as shown in FIG. 2. The front flap 1 , viewed in the direction of travel FR, is attached to its rear end section in the area of the so-called cowl of the motor vehicle and opens from the front of the vehicle. The articulated arms 4 and 5 are articulated on the one hand via joints 6 and 7 on the front flap 1 and on the other hand via articulations 8 and 9 on a hinge bracket 10 . Of course, the hinge device 2 can also be formed by a differently constructed multi-joint hinge or a single hinge. The hinge bracket 10 virtually forms the base plate for the hinge device 2 . According to the invention, the hinge bracket 10 is articulated to its front end section via an axis of rotation 11 with a screw-on plate 12 . The screw-on plate 12 is in turn screwed to the support bracket 3 by screws 13 . At its rear end section, the hinge bracket 10 is locked in the position shown in FIGS. 1 and 2 via a locking device 14 with an eccentrically mounted bolt 15 . At a distance d (see FIG. 3) from the axis of rotation 11 , an energy-storing device 17 acts on the underside 16 of the hinge bracket 10 . The energy-saving device 17 consists essentially of a helical spring 18 which is used with an inner core 19 in a cup-shaped recess 20 of the support beam 3 . At the upper end portion of the coil spring 18 , a connecting piece 21 is arranged, which has a joint 22 for connection to the hinge bracket 10 .

Fig. 1 zeigt die Frontklappe 1 in ihrer geschlossenen Position. Der Scharnierträ­ ger 10 befindet sich in seiner gestreckten Lage in Verlängerung der Anschraub­ platte 12 und ist über den Riegel 15 in dieser Lage fixiert. Fig. 1 shows the front flap 1 in its closed position. The Scharnierträ ger 10 is in its extended position in the extension of the screw plate 12 and is fixed in this position via the bolt 15 .

In Fig. 2 ist die Frontklappe 1 in ihrer geöffneten Stellung dargestellt, in der sie von der Vorderseite des Kraftfahrzeuges einen Zugang zu dessen Motorraum er­ möglicht. Der Scharnierträger 10 befindet sich nach wie vor in der unter Fig. 1 beschriebenen Position.In Fig. 2, the front flap 1 is shown in its open position, in which it allows access to the engine compartment from the front of the motor vehicle. The hinge bracket 10 is still in the position described in FIG. 1.

Fig. 3 zeigt den Zustand nach einer Verlagerung der Frontklappe 1 infolge einer Kollision des Kraftfahrzeugs mit einem Fußgänger. Eine Sensorik im vorderen Be­ reich des Kraftfahrzeuges, die beispielsweise in der Stoßleiste eines Stoßfängers unterbracht ist, steuert bei Erkennen einer Kollision mit einem Fußgänger die Ver­ riegelungseinrichtung 14 an. Nachfolgend wird der Riegel 15 verdreht und gibt den Scharnierträger 10 frei, der unter der Vorspannung der Schraubenfeder 18 in Richtung des Pfeils 23 nach oben schnellt und eine Verlagerung der Frontklappe um den Betrag s bewirkt. Hierdurch wird im rückwärtigen Bereich der Frontklappe 1 ein Abstand gegenüber der nur schwer deformierbaren Unterstruktur des Kraftfahr­ zeugs in diesem Bereich geschaffen, während die Frontklappe 1 an ihrer Vorder­ kante um eine nicht dargestellte Verriegelungseinrichtung verschwenkt wird. Die beiden Gelenkarme 4 und 5 halten dabei über den Scharnierträger 10 und die An­ schraubplatte 12 die Anbindung an den Stützträger 3 aufrecht. Hierdurch wird ver­ hindert, daß die Frontklappe 1 sich aus ihrer vorderen Verankerung löst und bei­ spielsweise bei einem stärkeren Fahrzeugaufprall in die Windschutzscheibe des Kraftfahrzeuges eindringt. Außerdem wird durch die erfindungsgemäße Anordnung erreicht, daß bei entsprechend großen Kräften in Längsrichtung der Frontklappe 1 diese in Richtung ihrer Ausgangslage, wie in Fig. 1 dargestellt, zurückverlagert wird. Fig. 3 shows the state after a displacement of the front door 1 due to a collision of the motor vehicle with a pedestrian. A sensor system in the front loading area of the motor vehicle, which is accommodated, for example, in the bumper strip of a bumper, controls the locking device 14 when a collision with a pedestrian is detected. Subsequently, the latch 15 is rotated and releases the hinge bracket 10 which, under the pretension of the coil spring 18, shoots up in the direction of the arrow 23 and causes the front flap to shift by the amount s. This creates in the rear area of the front flap 1 a distance from the difficult to deform substructure of the motor vehicle in this area, while the front flap 1 is pivoted at its front edge by a locking device, not shown. The two articulated arms 4 and 5 hold the connection to the support bracket 3 via the hinge bracket 10 and the screw plate 12 . This prevents ver that the front flap 1 comes loose from its front anchorage and penetrates into the windshield of the motor vehicle, for example, in the event of a stronger vehicle impact. In addition, it is achieved by the arrangement according to the invention that, with correspondingly large forces in the longitudinal direction of the front flap 1 , it is displaced back in the direction of its starting position, as shown in FIG. 1.

Die Schraubenfeder 18 weist bevorzugt eine lineare oder progressive Kennlinie auf, um in der Anfangsphase des Auftreffens des Fußgängers auf die Frontklappe 1 einen relativ weich einsetzenden Verzögerungsverlauf zu erreichen.The coil spring 18 preferably has a linear or progressive characteristic curve in order to achieve a relatively smooth deceleration curve in the initial phase of the pedestrian hitting the front flap 1 .

Fig. 4 zeigt ein zweites Ausführungsbeispiel der Erfindung. Die geschlossene Position der Frontklappe 101 ist hierbei mit durchgezogenen Linien dargestellt, während die gestrichelten Linien den Zustand nach einer Verlagerung der Front­ klappe 101 infolge einer Kollision des Kraftfahrzeugs mit einem Fußgänger ange­ ben. Fig. 4 shows a second embodiment of the invention. The closed position of the front flap 101 is shown here with solid lines, while the dashed lines indicate the state after a shift of the front flap 101 due to a collision of the motor vehicle with a pedestrian ben.

Die Frontklappe 101 ist über eine Scharniereinrichtung 102 an einem Stützträger 103 gelagert. Die Scharniereinrichtung 102 wird von zwei Gelenkarmen 104 und 105 eines Viergelenkes gebildet, die zwischen einem karosserieseitigen und einem frontklappenseitigen Scharnierträger 110 bzw. 130 angeordnet sind. Der Scharnier­ träger 110 weist zwei vertikal nach unten gerichtete, leicht bogenförmig gekrümmte Führungsarme 131 und 132 mit jeweils einem Führungsschlitz 133 auf. In die Füh­ rungsschlitze 133 greifen karosseriefeste Führungsstifte 134 und 135 ein.The front flap 101 is mounted on a support bracket 103 via a hinge device 102 . The hinge device 102 is formed by two articulated arms 104 and 105 of a four-bar linkage, which are arranged between a body-side and a bonnet-side hinge bracket 110 and 130 , respectively. The hinge bracket 110 has two vertically downward, slightly curved guide arms 131 and 132 , each with a guide slot 133 . In the Füh approximately slots 133 engage body pins 134 and 135 .

Bei Erkennen einer Kollision des Fahrzeugs mit einem Fußgänger wird mittels der oben beschriebenen Sensorik und einer nicht dargestellten Verriegelungseinrich­ tung der Scharnierträger 110 freigegeben. Nunmehr verlagert eine nicht darge­ stellte energiespeichernde oder energiefreisetzende Einrichtung, die an der Unter­ seite des Scharnierträgers 110 angreift, den Scharnierträger 110 und damit die Frontklappe 101 entsprechend dem Pfeil 123 nach oben. Hierbei schwenkt die Frontklappe 101 kreisbogenförmig um ihre vordere Verriegelungseinrichtung 136, so daß die Frontklappe in ihrem rückwärtigen Bereich um den Weg s' angehoben wird. Die unteren Enden der Führungsschlitze 133 bilden hierbei eine Wegbegren­ zung für die Aufwärtsbewegung der Frontklappe 101, während in der geschlosse­ nen Position der Frontklappe 101 bzw. bei einer Öffnung der Frontklappe 101 von ihrer Vorderseite aus die Führungsstifte 134 und 135 an den oberen Begrenzun­ gen der Führungsschlitze 133 anliegen.When a collision of the vehicle with a pedestrian is detected, the hinge bracket 110 is released by means of the sensor system described above and a locking device (not shown). Now a not shown Darge presented energy-storing or energy-releasing device that attacks the underside of the hinge bracket 110 , the hinge bracket 110 and thus the front flap 101 according to the arrow 123 upwards. Here, the front flap 101 pivots in a circular arc around its front locking device 136 , so that the front flap is raised in its rear region by the path s'. The lower ends of the guide slots 133 form a path limitation for the upward movement of the front flap 101 , while in the closed position of the front flap 101 or when the front flap 101 is opened from its front, the guide pins 134 and 135 at the upper limits of the Fit guide slots 133 .

Das Ausführungsbeispiel gemäß Fig. 5 zeigt eine weitere Kulissenführung für eine Scharniereinrichtung 202, die ebenfalls als Viergelenk-Anordnung ausgebildet ist. Die Gelenkarme 204 und 205 sind zwischen einem karosserieseitigen und einem frontklappenseitigen Scharnierträger 210 bzw. 230 angeordnet. Der Schar­ nierträger 210 ist über ein Zwischenelement 250 mit einem kolbenförmigen Füh­ rungselement 251 verbunden. Das Führungselement 251 ist verschieblich in einer zylinderförmigen Kulisse 252 geführt, die bevorzugt starr an der Karosserie 203 des Fahrzeugs angeordnet ist. Die Kulisse 252 nimmt ferner eine energiespei­ chernde Einrichtung 217 in Form einer Schraubenfeder 218 auf.The embodiment of Fig. 5 shows a further slotted guide for a hinge device 202, which is also formed as a four-joint arrangement. The articulated arms 204 and 205 are arranged between a body-side and a bonnet-side hinge bracket 210 and 230 , respectively. The hive kidney carrier 210 is connected via an intermediate element 250 with a piston-shaped guide element 251 . The guide element 251 is slidably guided in a cylindrical link 252 , which is preferably arranged rigidly on the body 203 of the vehicle. The backdrop 252 also receives an energy-saving device 217 in the form of a coil spring 218 .

Bei Erkennen einer Kollision des Fahrzeugs mit einem Fußgänger wird eine Verrie­ gelungseinrichtung 214 angesteuert, die beispielsweise auf elektromagnetischem Weg einen Riegel 215 aus dem Inneren der Kulisse 252 herausbewegt und hier­ durch das Führungselement 251 freigibt. Durch die Vorspannung der Schrauben­ feder 218 wird nunmehr der Scharnierträger 210 und mit ihm die Frontklappe 201 in Richtung des Pfeils 223 nach oben verlagert. Ein Anschlag 253 begrenzt den Verlagerungsweg und verhindert ein Eindringen der rückwärtigen Kante der Front­ klappe 201 in die nicht dargestellte Windschutzscheibe des Kraftfahrzeugs. Auf­ grund der Schrägstellung der Kulisse 252 ist die vordere Lagerung der Frontklappe 201 mit einem Freiheitsgrad in Fahrzeuglängsrichtung zu versehen.When a collision of the vehicle with a pedestrian is detected, a locking device 214 is actuated, which, for example, moves a bolt 215 out of the interior of the link 252 by electromagnetic means and releases it here by the guide element 251 . Due to the bias of the coil spring 218 , the hinge bracket 210 and with it the front flap 201 is now displaced in the direction of arrow 223 upwards. A stop 253 limits the displacement and prevents penetration of the rear edge of the front flap 201 in the windshield of the motor vehicle, not shown. Due to the inclined position of the link 252 , the front mounting of the front flap 201 is to be provided with a degree of freedom in the longitudinal direction of the vehicle.
