Description

Haube für Kraftfahrzeuge Die Erfindung betrifft eine Haube für einen Koffer- und/ oder Motorraum eines Kraftfahrzeuges, welche ein äußeres undein inneres Pressteil umfasst , die entlang zumindest eines Teiles des Haubenrandes gemeinsam ein Hohlprofil bilden. Hood for motor vehicles The invention relates to a hood for one Trunk and / or engine compartment of a motor vehicle, which have an outer and an inner Comprises pressed part, which is common along at least part of the hood edge form a hollow profile.

Eine derartige Ausbildung der Haube ergibt eine genügende Verbindungssteifigkeit derselben. Es ist jedoch keine befriedigende Lösung, weil nur der Rand der Haube, aber nicht die Oberfläche des Außenbleches gegen unerwünschte Verformung geschützt ist. Insbesondere beim Schließen der Haube kann beim Niederdrücken derselben von Hand das äußere Blechteil leicht eingedrückt werden. Das Ausbessern derartiger Schäden ist kostspielig. Such a design of the hood results in sufficient stiffness of the connection the same. However, it is not a satisfactory solution because only the edge of the hood, but not the surface of the outer sheet is protected against undesired deformation is. In particular, when closing the hood, when it is depressed, from The outer sheet metal part can be pressed in slightly by hand. Mending such damage is costly.

Zur Vermeidung der angeführten Nachteile wird gemäß der Erfindung vorgeschlagen, daß das Hohlprofil mit einem formsteifen Schaumstoff ausgeschäumt ist. Das innere Pressteil der Haube ist im Bereich des -Hohlprofiles mit Öffnungen versehen, durch welche die den Schaumstoff bildenden Komponenten eingebracht werden. To avoid the disadvantages mentioned, according to the invention suggested that the hollow profile be filled with a dimensionally stable foam is. The inner pressed part of the hood is in the area of the hollow profile with openings provided, through which the components forming the foam are introduced.

Durch die Erfindung wird nicht nur die Randzone der Haube zusätzlich versteift, sondern insbesondere erhält die Oberfläche des Außenbleches eine bessere Stabilität gegen unerwünschtes Verformen derselben beim Schließen. Die Herstellungskosten sind gering. Die Anwendung eines Schaumstoffes, der selbständig Nach dem Einbringen in den Hohlraum des Profiles erhärtet, ist auch zeitsparend. Die Schwingungen der Haube beim Fahren werden zusätzlich durch die erfindungsgemäßen Vorkehrungen herabgesetzt, da durch den im Profilhohlraum befindlichen Schaumstoff eine entsprechende Spannung des äußeren Pressteiles erzielt wird. Es werden daher die unerwünschten Geräusche während der Fahrt eines Kraftfahrzeuges weiter herabgesetzt. Dies ist insbesandere bei großflächigen Hauben von besonderer Bedeutung. Ein weiterer Vorteil ist, daß der auf die Haubenoberfläche aufgebrachte Lacküberzug weitgehend geschont wird und er löst sich nicht durch Abblättern oder Abspringen. The invention not only adds to the edge zone of the hood stiffened, but in particular the surface of the outer sheet is given a better one Stability against undesired deformation of the same when closing. The manufacturing cost are low. The application of a foam that automatically after the introduction hardened in the cavity of the profile is also time-saving. The vibrations of the Hood while driving are additionally reduced by the precautions according to the invention, because of the foam in the profile cavity a corresponding Tension of the outer pressing part is achieved. It therefore becomes the undesirable Noise while driving a motor vehicle further reduced. This is Particularly important for large hoods. Another advantage is that the paint coating applied to the hood surface is largely spared and does not come off by peeling or peeling off.

In der Zeichnung, in welcher eine beispielsweise Ausführungsform der Erfindung wiedergegeben ist, ist ein Schnitt durch den Rand einer Haube und die angrenzenden Aufbauteile eines Kraftfahrzeuges dargestellt. In the drawing, in which an example embodiment of the invention is shown is a section through the edge of a hood and the adjacent structural parts of a motor vehicle are shown.

Die Haube 1 umfasst ein äußeres Pressteil 2 und ein inneres Pressteil 3, die bei 4 miteinander beispielsweise durch Börteln verbunden sind. Eine weitere Verbindung zwischen dem äußeren und dem inneren Pressteil kann bei 5 vorgesehen sein. Hierzu weist das innere Pressteil 3 einen dem Verlauf des äußeren Pressteiles 2 angepassten Flansch 6 auf 0 Das äußere oder innere Pressteil 2, 5 bilden ein Hohlprofil 7, welches erfindungsgemäß ausgeschäumt ist. Hierzu ist das innere Pressteil 3 mit vorzugsweise mehreren Öffnungen 8 versehen, durch welche der Schaumstoff bzw die Komponenten desselben in das Hohlprofil 7 eingeführt werden. Sobald der Schaumstoff ausgehärtet ist, bildet er einen steifen Körper 9, der das Hohlprofil 7 gänzlich ausfüllt. Gleichzeitig wird das äussere Pressteil 2 im Bereich des Hohlproriles vom Schaumstoffkörper 9 unter Spannung gesetzt. The hood 1 comprises an outer pressing part 2 and an inner pressing part 3, which are connected to one another at 4, for example by crimping. Another Connection between the outer and the inner pressing part can be provided at 5 be. For this purpose, the inner pressing part 3 has the shape of the outer pressing part 2 adapted flange 6 to 0 The outer or inner pressed part 2, 5 form a hollow profile 7, which is foamed according to the invention. For this purpose, the inner pressed part 3 is included preferably a plurality of openings 8 through which the foam or the Components of the same are introduced into the hollow profile 7. Once the foam is cured, it forms a rigid body 9, which the hollow profile 7 completely fills out. At the same time, the outer pressed part 2 is in the area of the hollow profile placed under tension by the foam body 9.

Am inneren Pressteil 3 ist ein als Blechpressteil ausgebildetes Formteil 10 angebracht, welches zur Befestigung eines Bolzens 11 dient. Dieser Bolzen 11 wirkt mit einer Halterung 12 zusammen, die in einem Träger 15 des Aufbaues des Kraftfahrzeuges angeordnet ist. On the inner pressed part 3 is a molded part designed as a sheet metal pressed part 10 attached, which is used to attach a bolt 11. This bolt 11 cooperates with a holder 12, which is in a support 15 of the body of the motor vehicle is arranged.

Das Schließen der Haube 1, insbesondere das Niederdrücken derselben in die Schließstellung, kann im Bereich des Hohlprofiles 7 durch die Ausschäumung kein Eindrücken des äußeren Pressteiles zur Folge haben, wodurch dieses vor Beschädigung geschützt ist. Closing the hood 1, in particular pressing it down in the closed position, can in the area of the hollow profile 7 by the foam do not result in any indentation of the outer pressed part, which protects it from damage is protected.
