Description
Die vorliegende Erfindung betrifft eine Karosserie für ein Kraftfahrzeug mit einem Rahmen und wenigstens einem an dem Rahmen befestigten, bei einem Unfall aus einer Ruhestellung in eine vorgeschobene Stellung mit Hilfe von wenigstens einem Stellglied beweglichen plattenförmigen Element.The The present invention relates to a body for a motor vehicle having a Frame and at least one attached to the frame, at a Accident from a rest position to an advanced position with Help of at least one actuator movable plate-shaped element.
Eine
Karosserie, bei der das plattenförmige Element
eine Fronthaube ist, ist in
Aufgabe der Erfindung ist, eine Kraftfahrzeugkarosserie der eingangs angegebenen Art zu schaffen, bei der die Wirksamkeit des Fußgängeraufprallschutzes nach dem Übergang des plattenförmigen Elements in seine vorgeschobene Stellung besser gewährleistet ist.task The invention is a motor vehicle body of the aforementioned To create a way in which the effectiveness of pedestrian impact protection after the transition of the plate-shaped Elements in its advanced position better ensured is.
Die Aufgabe wird dadurch gelöst, dass wenigstens ein Dämpfungsglied an dem plattenförmigen Element beabstandet von jedem Stellglied angreift, um eine durch die Verlagerung des plattenförmigen Elements in die vorgeschobene Stellung angeregte Schwingung des plattenförmigen Elements zu dämpfen.The Task is solved by that at least one attenuator on the plate-shaped Element spaced from each actuator engages to a through the displacement of the plate-shaped Element in the advanced position excited vibration of the disc-shaped Dampen elements.
Einer bevorzugten Anwendung der Erfindung zufolge ist das plattenförmige Element eine Fronthaube, doch ist die Erfindung grundsätzlich auch auf andere plattenförmige Karosserieteile wie etwa Kotflügel, Heckklappen, anwendbar.one preferred application of the invention, according to the plate-shaped element a front hood, but the invention is basically also on other plate-shaped body parts like fenders, Tailgate, applicable.
Vorzugsweise greift das Dämpfungsglied symmetrisch zwischen zwei Stellgliedern an dem plattenförmigen Element an, um wenigstens einen Grundschwingungsmodus des plattenförmigen Elements wirksam zu dämpfen.Preferably grips the attenuator symmetrically between two actuators on the plate-shaped element to at least a basic mode of vibration of the plate-shaped member effectively dampen.
Bevorzugt ist auch, dass das Dämpfungsglied in der Verlagerungsrichtung reckbar ist, und nur in gereck tem Zustand die Verlagerung des plattenförmigen Elements bis in die vorgeschobene Stellung ohne eine gleichzeitige Verformung des plattenförmigen Elements zulässt. Ein solches Dämpfungsglied beginnt bereits, den Bereich des plattenförmigen Elements, an dem es angreift, abzubremsen, bevor die Stellglieder ihre Anschlagstellung erreicht haben, um so zumindest weitgehend zu verhindern, dass ein Bereich des plattenförmigen Elements, an dem das Dämpfungsglied angreift, sich über die Gleichgewichtslage in der vorgeschobenen Stellung hinausbewegt.Prefers is also that the attenuator is stretchable in the direction of displacement, and only in stretched tem state the displacement of the plate-shaped Elements to the advanced position without a simultaneous Deformation of the plate-shaped Elements allows. Such an attenuator begins already, the area of the plate-shaped element on which it attacks, decelerates before the actuators their stop position have at least largely prevented that from happening Area of the plate-shaped Elements on which the attenuator attacks, over the equilibrium position is moved out in the advanced position.
Um den Übergang des plattenförmigen Elements in die vorgeschobene Stellung nicht wesentlich zu verlangsamen, ist das Dämpfungsglied vorzugsweise so ausgelegt, dass es eine Verlagerung des plattenförmigen Elements über den größeren Teil des Weges in die vorgeschobene Stellung zulässt, ohne dabei gereckt zu werden. Eine Reckung und eine eventuell damit verbundene Verlangsamung des Übergangs in die vorgeschobene Stellung tritt somit erst gegen Ende des Übergangs ein.Around the transition of the plate-shaped Not slow down elements to the advanced position significantly, is the attenuator preferably designed so that there is a displacement of the plate-shaped element over the larger part of Way to the advanced position allows, without being stretched too become. A stretching and a possibly associated slowdown of the transition in the advanced position thus occurs only towards the end of the transition one.
Einer besonders einfachen und preiswerten Lösung zufolge umfasst das Dämpfungsglied ein flexibles Band oder Seil, das sich zwischen Angriffspunkten am Rahmen und am Karosserieteil erstreckt.one particularly simple and inexpensive solution involves the attenuator a flexible band or rope that extends between points of attack extends on the frame and on the body part.
Vorzugsweise sind ferner zwei Enden des Bandes oder Seils an voneinander beabstandeten Angriffspunkten des plattenförmigen Elements gehalten, und das Band oder Seil ist um einen Angriffspunkt am Rahmen herumgeschlungen.Preferably are also two ends of the tape or rope at spaced attack points of the plate-shaped Elements held, and the tape or rope is around a point of attack wrapped around the frame.
Das Band oder Seil kann aus in einer reckbaren Konfiguration verwobenen, verflochtenen oder verseilten Fasern gebildet sein, oder die Fasern, aus denen das Band oder Seil gebildet ist, können in sich reckbar sein.The Ribbon or rope can be woven from in a stretchable configuration, interlaced or stranded fibers, or the fibers, from which the band or rope is formed, can be stretched in itself.

Schwingungsdämpfende reckbare Bänder können auch an den Längskanten oder der Vorderkante der Haube oder inmitten der Haube angreifen. So kann es z. B. zweckmäßig sein, die Schwingungen, die durch das Anheben in der Haube angeregt werden, experimentell zu untersuchen oder zu simulieren, um den oder die Punkte mit der größten Schwingungsamplitude herauszufinden, und ein Band an diesen Punkten zu befestigen. Insbesondere bei einer festen Haube, d.h. einer Haube, die nicht zum Zugreifen auf den Motor aufklappbar ist, ist dies ohne Einschränkungen möglich.Vibration-damping stretchable bands can also attack the longitudinal edges or the leading edge of the hood or in the middle of the hood. So it may be z. B. be useful, the vibrations excited by the lifting in the hood to experimentally investigate or simulate to find out the point or points with the greatest vibration amplitude, and to attach a band at these points. In particular, in a fixed hood, ie a hood that is not hinged to access the engine, this is possible without restrictions.
Bei einer aufklappbaren Haube ist sicherzustellen, dass die Bänder ein Hochklappen der Haube zum Zugreifen auf den Motor nicht behindern. So kann z. B., wenn ein Band an der Vorderkante der Haube angebracht werden soll, am Haubenschloss eine Sollbruchstelle oder eine lösbare Verbindung zwischen der Haube und einem in eine Aufnahme des Karosserierahmens einrückenden Zapfen vorgesehen werden, die bricht bzw. gelöst wird, wenn bei einem Unfall die Haube angehoben wird, so dass der Zapfen in der Aufnahme zurückbleibt, und ein reckbares Band ist zwischen der Haube und dem Zapfen angebracht, um beim Anheben gereckt zu werden.at A hinged hood is to ensure that the tapes are one Do not obstruct the folding of the hood to access the engine. So z. Example, when a tape attached to the front edge of the hood is to be on the hood lock a breaking point or a detachable connection between the hood and an engaging in a receptacle of the body frame Pins are provided, which breaks or is released when in an accident the hood is raised so that the pin remains in the receptacle, and a stretchable band is mounted between the hood and the pin, to be stretched while lifting.
