Abstract
Description
Die Erfindung bezieht sich auf ein Fahrzeug, insbesondere Personenkraftwagen, mit einer Frontklappe, welche durch einen pyrotechnischen Aktuator aus ihrer Schließstellung in eine angehobene Schutzstellung bewegbar ist, wobei zumindest ihr der Windschutzscheibe des Fahrzeugs zugewandte Bereich über mindestens ein Scharnier anhebbar ist.The The invention relates to a vehicle, in particular a passenger car, with a front flap, which by a pyrotechnic actuator from its closed position to a raised protective position is movable, at least her the windshield of the vehicle facing area over at least one hinge liftable is.
Gattungsgemäße Anordnungen sind in den vielfältigsten Variationen bekannt. Sie dienen dazu, das Verletzungsrisiko eines auf die Frontklappe aufschlagenden Fußgängers oder Zweiradfahrers zu reduzieren.generic Arrangements are known in the most varied variations. They serve to reduce the risk of injury to the front door striking pedestrian or two-wheeler to reduce.
Zum Anheben der Frontklappe in ihre Schutzstellung werden meist pyrotechnische oder hydraulische Systeme eingesetzt. Die kostengünstiger umsetzbaren pyrotechnischen Systeme haben den Nachteil, dass der Druck relativ schnell abfällt. Das bedeutet, dass die Frontklappe nur eine relativ kurze Zeit in ihrer angehobenen Schutzstellung verbleibt. Dies kann sich nachteilig bei einem Mehrfachaufschlag oder dann auswirken, wenn über sogenannte Pre-Crash-Sensoren ein möglicher Aufschlag detektiert und darüber vor dem eigentlichen Aufschlag die Frontklappe in die Schutzstellung bewegt wird.To the Lifting the front flap in its protective position are usually pyrotechnic or hydraulic systems used. The cheaper implementable pyrotechnic systems have the disadvantage that the Pressure drops relatively quickly. That means the front door only a relatively short time in its raised protective position remains. This can be disadvantageous in a multiple surcharge or impact when using so-called pre-crash sensors detected a possible impact and above before the actual impact, the front flap in the protective position is moved.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, bei Verwendung von pyrotechnischen Aktuatoren sicher zu stellen, dass die Frontklappe eine längere Zeit in der angehobenen Schutzstellung verbleibt.Of the present invention is based on the object when using of pyrotechnic actuators to ensure that the front door a longer time remains in the raised protective position.
Die Aufgabe wird dadurch gelöst, dass beim Anheben der Frontklappe das Scharnier eine im Wesentlichen freie Drehung der Frontklappe ermöglicht und dass die Bewegung der Frontklappe von der angehobenen Schutzstellung in die Schließstellung gedämpft erfolgt. Durch die Dämpfung wird erreicht, dass die Frontklappe auch dann, wenn der pyrotechnische Aktuator drucklos ist, in der Schutzstellung verbleibt bzw. sich nur geringfügig absenkt. Durch die erfindungsgemäße Ausgestaltung wird nicht nur der vorstehend genannte Vorteil erzielt, sondern darüber hinaus auch das Verletzungsrisiko eines auf die Frontklappe aufschlagenden Fußgängers oder Zweiradfahrers reduziert, da die Dämpfung als Energiewandler wirkt. Über die Abstimmung der Momentenkennungen ist es möglich, dieses Verhalten für einen großen Bereich abzustimmen.The Task is solved by lifting the front door the hinge is a substantially free rotation of the front door allows and that the movement of the front flap of the raised guard position damped in the closed position he follows. By the damping is achieved that the front flap even if the pyrotechnic actuator is depressurized, in the Protective position remains or only slightly lowered. By the embodiment according to the invention is not only achieves the above advantage, but beyond also the risk of injury of impacting the front door Pedestrian or two-wheeler reduced as the Damping acts as an energy converter. About the vote The moment labels make it possible for this behavior to vote for a large area.
Zur Erzielung der gewünschten unterschiedlichen Momentenkennungen können an sich alle bekannten Maßnahmen Verwendung finden die geeignet sind, eine Translations- oder Rotationsbewegung in einer Richtung zu dämpfen und eine im Wesentlichen ungehinderte Bewegung in die entgegengesetzte Richtung zu erlauben.to Achieving the desired different moment identifiers can use all known measures per se which are suitable for translational or rotational movement in to dampen a direction and a substantially unhindered one To allow movement in the opposite direction.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung kann die Dämpfung über einen separaten Dämpfer erfolgen, welcher an einem Scharnierarm des Scharniergelenks angreift. Solche separaten Dämpfer sind sehr kostengünstig und robust.According to one advantageous embodiment of the invention, the damping over a separate damper, which on a hinge arm of the Hinge joint attacks. Such separate dampers are very cost effective and robust.
