Description

Stoßaufriehmendes Karosserieteil für Kraftfahrzeuge Die Erfindung betrifft ein stoßaufnehmendes Karosserieteil für Kraftfahrzeuge wie Haube, Deckel und dergleichen. Bumper-Raising Body Panel for Motor Vehicles The Invention relates to a shock-absorbing body part for motor vehicles such as hood, lid and the same.

Motorhauben, Kofferraumdeckel und andere derartige Abdeckteil an Kraft fahrzeuges bestehen in bekannter Weise aus einem geformten Blech, welches durch ein Innenrahmenteil verstärkt wird und an dem Scharniere, Anlenkungen und ähnliches befestigt ists Nachteilig wirkt sich diese Bauart bei einem Zusammenstoß aus; denn die Haube oder der Deckel verbiegt sich und die nicht mehr aufzunehmende Stoßenergie wird von der restlichen Karosserie aufgenommen. Bonnets, trunk lids and other such cover parts Motor vehicle consist in a known manner from a shaped sheet, which is reinforced by an inner frame part and on which hinges, articulations and similar attached is disadvantageous, this type of construction has a collision the end; because the hood or the lid bends and the one that can no longer be accommodated Impact energy is absorbed by the rest of the body.

Insbesondere verschieben sich die Anlenkpunkte für die Haube wie für den Deckel, welches eine starke Beschädigung benachbarter Karosserieteile nach sich zieht. In particular, the articulation points for the hood shift like for the lid, which shows severe damage to adjacent body parts draws itself.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, Karosserieteile der eingangs genannten Art zu schaffen, die energieverzehrend wirken, derart, daß bis zu einer bestimmten Stoßgröße benachbart der Haube und des Deckels liegende Teile nur geringfügig beschädigt werden. In contrast, the invention is based on the object of body parts to create the type mentioned, which have an energy-consuming effect, such that up to a certain joint size adjacent to the hood and the lid Parts are only slightly damaged.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Karosserieteil im Innenrahmenblech und/oder in seiner Hauben-und Deckelfläche als Sollbiegestellen ausgebildete EindMickungen, Einkerbungen und dergleichen aufweist. This object is achieved according to the invention in that the body part in the inner frame sheet and / or in its hood and cover surface as predetermined bending points has formed thickenings, notches and the like.

Mit dem erfindungsgemäß ausgebildeten Karosserieteil ist vorteilhafterweise erreicht, daß sie bei einem Stoß entgegen der Fahrtrichtung eine vorbestimmte Verformung annehmen, energieverzehrend wirken und die Beschädigungen an der übrigen Karosserie gering gehalten werden. With the body part designed according to the invention is advantageous achieves a predetermined deformation in the event of a shock against the direction of travel assume, have an energy-consuming effect and the damage to the rest of the body be kept low.

Ferner ist nach der Erfindung vorgesehen, daß das Innenrahmenblech mehrere Absetzungen nach Art von Stufen aufweist, die treppenförmig ansteigend ausgebildet sind. Furthermore, it is provided according to the invention that the inner frame plate has several depositions in the manner of steps, which rise in steps are.

Ein AusfUhrungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen Fig. 1 eine Seitenansicht im Schnitt durch eine Motorhaube, und Fig. 2 und 3 eine Seitenansicht im Schnitt durch ein weiteres Ausftihrungsbeispiel der Erfindung. An exemplary embodiment of the invention is shown in the drawing and is described in more detail below. 1 shows a side view in FIG Section through a hood, and FIGS. 2 and 3 show a side view in section another embodiment of the invention.

Die Haube besteht aus einem oberen Blech 1 (Aussenblech) und einem unteren Blech, dem Innenrahmenblech 2. Zwischen beiden Blechen 1 und 2 kann gegebenenfalls eine Kunstmasse 5 vorgesehen sein. Das Innenrahmenblech 2 ist unmittelbar mit dem Aussenblech 1 verbunden. The hood consists of an upper sheet 1 (outer sheet) and a lower sheet, the inner frame sheet 2. Between the two sheets 1 and 2 can optionally an artificial mass 5 may be provided. The inner frame sheet 2 is directly with the Outer panel 1 connected.

Das Innenrahmenblech 2 weist quer zur Fahrtrichtung 4 eingeformte EindrUckungen 3, Einkerbungen usw. auf, die als Sollbiegestellen dienen. The inner frame sheet 2 is formed transversely to the direction of travel 4 Indentations 3, notches, etc., which serve as intended bending points.

Bei einem Stoß in Richtung des Pfeiles 4 wird von der Haube bzw. dem Deckel Energie aufgenommen und die Haube bzw. der Deckel kann sich aufgrund der festigkeitsvermindernden Einformungen quer zur Fahrtrichtung entsprechend selben. In the event of an impact in the direction of arrow 4, the hood or the cover absorbed energy and the hood or the cover can be due to the same as the strength-reducing indentations across the direction of travel.

Es würden auch schon wenige Eindrückungen 3 genUgen (Fig. 3j, um diesen Effekt zu erzielen. Die Wölbung der Haube nach der Aufnahme eines Stoßes ist gestrichelt eingezeichnet. A few indentations 3 would suffice (Fig. 3j, in order to to achieve this effect. The curvature of the hood after receiving a shock is shown in dashed lines.

Bei der Ausftlhrungsform nach Fig. 2 weist das Innenrahmenblech 2 Absetzungen 6. in Form von Stufen auf, die zum Heck des Fahrzeuges hin treppenförmig ansteigen. In the embodiment according to FIG. 2, the inner frame plate 2 Deposits 6. in the form of steps, which are stepped towards the rear of the vehicle increase.

Durch die Eindrückungen 3, Einkerbungen, Absetzungen 6 und dergleichen im Innenrahmenblech 2 kann zum Beispiel ein vorderer Motordeckel, egal ob sich das Scharnier 7 vorne, hinten oder auf der Seite befindet. bei einem StoB in Richtung des Pfeiles 4 wölben (Fig. 3) und-die Vielzahl der hintereinander angeordneten Einformungen würden es erlauben, daß der Innenrahmen 3 und das Aussenblech 1 nicht nur an einer Stelle knickt, sondern sich mehrfach, zu einer großen Wölbung wölbt und damit auch mehr Energie aufgenommen werden kann. Through the indentations 3, notches, recesses 6 and the like In the inner frame sheet 2, for example, a front engine cover can be installed, regardless of whether it is Hinge 7 is located at the front, back or on the side. in the event of a bump in the direction of of the arrow 4 bulge (Fig. 3) and the plurality of recesses arranged one behind the other would allow the inner frame 3 and the outer panel 1 not only on one Place kinks, but bulges several times, to a large bulge and thus also more energy can be absorbed.
