Abstract

The vehicle door comprises a hollow member fixed to the inner door panel and extending in the longitudinal direction of the vehicle. Rigid polyurethane foam provides support inside the hollow member. In the transverse direction of the vehicle the hollow member (8) is easily deformable and has beads (11) running in the longitudinal direction.

Description

Die Erfindung betrifft eine Kraftfahrzeugtür gemäß dem Oberbe­ griff des Patentanspruchs 1.The invention relates to a motor vehicle door according to the Oberbe handle of claim 1.

Der hier interessierende Bereich einer derartigen Tür ist in ei­ nem Vertikalschnitt in Fig. 1 dargestellt. Die Tür ist zusammen­ gesetzt aus einem Türaußenblech 1 und einem Türinnenblech 2, die beide einen Schacht 3 zur Aufnahme einer verschiebbaren Fenster­ scheibe 4 begrenzen. Auf der dem Schacht 3 abgewandten Seite des Türinnenbleches 2 ist ein Träger 5 befestigt, der entweder als offenes Profil auf das Türinnenblech 2 aufgesetzt ist und zusam­ men mit diesem wie ein geschlossener Hohlträger wirkt oder schon als Hohlträger auf das Türinnenblech 2 gesetzt ist. Der Träger 5 gewährleistet, daß die Tür zunächst nach einem Frontalaufprall des Fahrzeugs unter vorgegebenen Bedingungen funktionsfähig bleibt, das heißt, sie wird in ihrem Ausschnitt nicht einge­ klemmt, so daß sie sich dann zumindest noch öffnen läßt. Der Trä­ ger 5 wird in seiner Funktion unterstützt von einem ihn zum Fahr­ zeuginnenraum hin abdeckenden Formblock 6 aus Hartschaum, der seinerseits von einer Türverkleidung 7 verdeckt ist. Zwar ist das aus Träger 5 und Formblock 6 gebildete Trägersystem dazu ausge­ legt, die sicherheitsrelevanten Bedingungen im Zusammenhang mit einem Frontalcrash zu erfüllen, doch läßt es sich auch dazu her­ anziehen, die Auflagen bei einem Seitencrash einzuhalten. Es ist leicht einzusehen, daß dazu das Trägersystem modifiziert werden muß. Dabei ist es sicher naheliegend, die Dicke des Formblocks 6 so zu vergrößern, daß die bei einem Seitencrash einzuhaltenden Beschleunigungswerte erreicht werden. Diese Lösung erfordert je­ doch - bei vorgegebenen äußeren Abmessungen des Fahrzeugs - Zuge­ ständnisse an die Fahrzeuginnenraumbreite, das heißt, die Sei­ tencrash-Bedingungen sind nur zu erfüllen, wenn man in Kauf nimmt, daß sich die Fahrgastraumbreite deutlich verringert, was natürlich den Komfort beeinträchtigt.The area of interest of such a door is shown in a vertical section in FIG. 1. The door is composed of a door outer panel 1 and a door inner panel 2 , both of which limit a shaft 3 for receiving a sliding window 4 . On the side facing away from the shaft 3 of the inner door panel 2 , a carrier 5 is fastened, which is either placed as an open profile on the inner door panel 2 and together with this acts as a closed hollow carrier or is already placed as a hollow carrier on the inner door panel 2 . The carrier 5 ensures that the door initially remains functional after a frontal impact of the vehicle under predetermined conditions, that is, it is not clamped in its cutout, so that it can then at least still be opened. The carrier 5 is supported in its function by a mold block 6 covering it towards the vehicle interior, made of rigid foam, which in turn is covered by a door trim 7 . Although the carrier system formed from carrier 5 and mold block 6 is designed to meet the safety-relevant conditions in connection with a frontal crash, it can also be used to comply with the requirements in the event of a side crash. It is easy to see that the carrier system must be modified for this. It is certainly obvious to increase the thickness of the mold block 6 so that the acceleration values to be maintained in the event of a side crash are achieved. This solution, however, requires - given the external dimensions of the vehicle - train concessions to the vehicle interior width, that is, the side crash conditions can only be met if one accepts that the passenger compartment width is significantly reduced, which of course affects comfort .

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Kraftfahrzeugtür dahingehend zu verbessern, daß die Seitencrash­ bedingungen erfüllt werden können, ohne daß die Fahrgastraumbrei­ te deswegen merklich verringert werden muß.The invention has for its object a generic Motor vehicle door to improve that the side crash conditions can be met without the passenger compartment te must therefore be reduced significantly.

Diese Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merk­ malen des Patentanspruchs 1 gelöst. Eine bevorzugte Ausführungs­ form ist Gegenstand des Unteranspruchs. Die erfindungsgemäße Lö­ sung hat darüber hinaus den Vorteil, daß Schaummaterial einge­ spart wird.This object is achieved with the characterizing note paint the claim 1 solved. A preferred execution form is the subject of the subclaim. The Lö according to the invention solution also has the advantage that foam material is saved.

Ein Ausführungsbeispiel der Erfindung wird anhand der Fig. 2 und 3 der Zeichnung nachfolgend näher erläutert. Darin ist in An­ lehnung an die Fig. 1 das Trägersystem einmal im Normalzustand (Fig. 2) und einmal nach dem Seitencrash (Fig. 3) dargestellt.An embodiment of the invention is explained below with reference to FIGS. 2 and 3 of the drawing. 1 in the carrier system once in the normal state (Fig. 2) and once after the side impact (Fig. 3) is in lehnung An to the Fig. FIG.

Das erfindungsgemäße Trägersystem besteht auch hier aus einem Hohlträger 8 und einem sich daran anschmiegenden Hartschaumblock 9 üblicher Dicke. Die dem Fahrzeuginnenraum zugekehrte Fläche 10 des Hohlträgers 8 ist mit in Längsrichtung verlaufenden Sicken 11 versehen, wodurch sich die Steifigkeit des Hohlträgers 8 in Quer­ richtung verringert, ohne daß seine Funktion bezüglich eines Frontalaufpralls beeinträchtigt ist. Bei einem Seitencrash, bei dem der benachbarte Fahrzeuginsasse gegen die Tür prallt, bietet das Trägersystem 8, 9 nun nicht mehr einen übermäßig großen Wi­ derstand, weil es sich - wie in Fig. 3 dargestellt - verformt und dabei Energie verzehrt, was dem Fahrzeuginsassen zugute kommt.The carrier system according to the invention also consists here of a hollow carrier 8 and a rigid foam block 9 of conventional thickness that clings to it. Which faces the vehicle interior surface 10 of the hollow beam 8 is provided with corrugations extending in the longitudinal direction 11, the stiffness of the hollow beam 8 in the transverse direction thereby reducing, without that its function is impaired in a frontal impact. In the event of a side crash in which the adjacent vehicle occupant hits the door, the carrier system 8 , 9 no longer offers an excessively large resistance because it deforms, as shown in FIG. 3, and thereby consumes energy, which benefits the vehicle occupant is coming.
