Description

PORTE DE VERMICULE AUTOMOBILE
L'invention concerne une porte de véhicule automobile qui possède un panneau porteur extérieur, une ossature intérieure et un cadre de renfort intérieur constitué par une première membrure verticale qui s'étend à proximité du chant avant de la porte, une deuxième membrure horizontale disposée entre une extrémité de la membrure verticale et l'extrémité d'une troisième membrure qui s1 étend obliquement à partir de l'autre extrémité de la membrure verticale et qui est reliée à l'extrémité de la membrure horizontale.MOTOR VEHICLE DOOR
The invention relates to a motor vehicle door which has an external support panel, an internal framework and an internal reinforcement frame constituted by a first vertical frame which extends near the front edge of the door, a second horizontal frame arranged between one end of the vertical member and the end of a third member which extends obliquely from the other end of the vertical member and which is connected to the end of the horizontal member.

La publication FR-A-2643859 décrit une porte de véhicule dans laquelle les membrures sont intégrées à un panneau de porte et surmoulées sur un renfort métallique.The publication FR-A-2643859 describes a vehicle door in which the members are integrated into a door panel and overmolded on a metal reinforcement.

La publication US-A-4.434.580 décrit une porte de véhicule comportant une première membrure verticale associée aux charnières d'articulation de la porte et une deuxième membrure verticale associée au support de la serrure de commande d'ouverture de la porte, une membrure horizontale et une membrure oblique.Publication US-A-4,434,580 describes a vehicle door comprising a first vertical member associated with the door hinges and a second vertical member associated with the support of the door opening control lock, a member horizontal and an oblique member.

Lorsque la porte subit un enfoncement latéral, la gravité des blessures occasionnées à l'occupant du véhicule dépend principalement de la localisation des renforts.When the door undergoes a lateral depression, the seriousness of the injuries caused to the occupant of the vehicle depends mainly on the location of the reinforcements.

L'invention a principalement pour objet une porte de véhicule à renforcement localise dans le but de réduire la résistance transversale de celle-ci en direction de l'occupant du véhicule.The subject of the invention is mainly a vehicle door with localized reinforcement in order to reduce the transverse resistance of the latter in the direction of the occupant of the vehicle.

L'invention a également pour objet une porte de véhicule à renfort localisé dans le but d'augmenter la rigidité longitudinale de la porte et la transmission des efforts entre la membrure verticale et un longeron latéral du véhicule.The invention also relates to a vehicle door with localized reinforcement in order to increase the longitudinal rigidity of the door and the transmission of forces between the vertical member and a lateral spar of the vehicle.

Selon l'invention la membrure oblique constitue l'élément de fermeture d'une traverse emboutie dans l'ossature intérieure et recouvre un renfort de jonction avec le chant de la porte ce dernier étant encastré dans ladite traverse pour porter un renfort de charnière.According to the invention, the oblique member constitutes the closing element of a cross member stamped in the internal framework and covers a reinforcement of junction with the edge of the door, the latter being embedded in said cross member to carry a hinge reinforcement.

L'ossature intérieure de la porte ainsi réalisée porte avantageusement l'ensemble des mécanismes et accessoires tels que le lève-vitre, la serrure, le dispositif arrêt-de-porte ainsi que le panneau de garnissage intérieur.The internal framework of the door thus produced advantageously carries all the mechanisms and accessories such as the window lifter, the lock, the door stop device as well as the interior trim panel.

L'assemblage final de la porte est de ce fait limité à la jonction de l'ossature avec le panneau porteur extérieur.The final assembly of the door is therefore limited to the junction of the frame with the external support panel.

L'invention sera mieux comprise à la lecture de la description détaillée, donnée ci-après à titre d'exemple, en référence au dessin annexé dans lequel: - la figure 1 est une représentation perspective de la porte conforme à
l'invention, - la figure 2 est une vue éclatée de la portè représentée à la figure 1, - les figures 3, 4, 5 représentent des coupes partielles de Ia porte suivant
les lignes m-m, W-IV, V-V de la figure 1.The invention will be better understood on reading the detailed description, given below by way of example, with reference to the appended drawing in which: - Figure 1 is a perspective representation of the door according to
the invention, - Figure 2 is an exploded view of the door shown in Figure 1, - Figures 3, 4, 5 show partial sections of the next door
the lines mm, W-IV, VV of figure 1.

En se reportant aux figures 1 et 2, la référence 10 désigne dans son ensemble la porte d'un véhicule. Pour des raisons de simplicité on a représenté une porte avant du véhicule, mais il est évident que les caractéristiques constructives de cette porte peuvent être transposées plus généralement à toute porte latérale du véhicule.Referring to Figures 1 and 2, the reference 10 designates the whole door of a vehicle. For reasons of simplicity, a front door of the vehicle has been shown, but it is obvious that the constructive characteristics of this door can be transposed more generally to any side door of the vehicle.

La porte 10 est constituée de manière conventionnelle par: - un panneau porteur extérieur 1 susceptible de se raccorder à la surface
générale de la carrosserie, - une ossature intérieure 2.The door 10 is conventionally constituted by: - an external support panel 1 capable of being connected to the surface
general bodywork, - an internal framework 2.

Le panneau extérieur et l'ossature intérieure 2 intègrent selon l'exemple représenté, des encadrements périphériques supérieurs désignés respectivement par les références Il et 21. Les encadrements 11, 21 sont disposés en vis-à-vis à la suite de l'assemblage du panneau 1 et de l'ossature 2 et délimitent l'entourage d'une vitre descendante non représentée.The external panel and the internal framework 2 incorporate, according to the example shown, upper peripheral frames designated respectively by the references II and 21. The frames 11, 21 are arranged opposite after the assembly of the panel 1 and the frame 2 and delimit the surround of a descending window not shown.

Selon l'invention, l'ossature intérieure 2 est constituée par un cadre fermé 3 comportant un certain nombre de segments emboutis dont les sections sont celles de profils en U.According to the invention, the internal framework 2 is constituted by a closed frame 3 comprising a number of stamped segments whose sections are those of U-shaped profiles.

L'ossature 2 possède de la sorte: - un montant avant 22 et un montant arrière 23, respectivement raccordés
à l'encadrement 21.The frame 2 thus has: - a front upright 22 and a rear upright 23, respectively connected
in management 21.

- une traverse inférieure 24 avec des extrémités respectivement
raccordées à la base des montants avant et arrière 22, 23.- a lower cross member 24 with ends respectively
connected to the base of the front and rear uprights 22, 23.

- une traverse oblique 25 avec des extrémités respectivement raccordées à
la partie haute du montant avant 22 et à la partie basse du montant
arrière 23.- an oblique cross 25 with ends respectively connected to
the upper part of the upright before 22 and the lower part of the upright
rear 23.

L'ossature 2 est fermée au niveau du montant 22 et des traverses 24, 25 par un cadre de renfort 30 sensiblement plan qui s'étend vers l'arrière à partir du chant avant 4 de la porte matérialisé par un bord tombé du montant avant 22.The frame 2 is closed at the level of the upright 22 and the crosspieces 24, 25 by a substantially planar reinforcement frame 30 which extends rearward from the front edge 4 of the door materialized by a fallen edge of the front upright 22.

Le cadre renfort 30 fermé représenté à la figure 2 est formé par une pièce découpée sensiblement plane et possède: - une première membrure verticale 31 qui recouvre le montant 22, - une deuxième membrure horizontale 32 qui recouvre Ia traverse
inférieure 24 de l'ossature 2 et s'étend entre une extrémité de la
membrure verticale 31 et l'extrémité d'une troisième membrure
oblique, - une troisième membrure oblique 33 qui recouvre la traverse oblique 25.The closed reinforcement frame 30 shown in FIG. 2 is formed by a substantially planar cut piece and has: - a first vertical member 31 which covers the upright 22, - a second horizontal member 32 which covers the cross member
lower part 24 of frame 2 and extends between one end of the
vertical member 31 and the end of a third member
oblique, - a third oblique frame 33 which covers the oblique crosspiece 25.

La troisième membrure 33 constitue l'élément de fermeture de la traverse oblique 25 et recouvre un renfort de jonction supérieur 34 de ladite traverse 25 avec le chant 4. The third frame 33 constitutes the closing element of the oblique cross-member 25 and covers an upper junction reinforcement 34 of said cross-member 25 with the edge 4.

De manière analogue la deuxième membrure 32 constitue l'élément de fermeture de la traverse inférieure 24 et recouvre un renfort de jonction inférieur 35 de ladite traverse 24 avec le chant 4 et la porte.Similarly, the second frame 32 constitutes the closing element of the lower cross member 24 and covers a lower joining reinforcement 35 of said cross member 24 with the edge 4 and the door.

L'encastrement des renforts 34, 35 dans les traverses respectives 25, 24 permet de rigidifier les jonctions entre le montant 22 et les traverses 25, 24 et de rapporter les renforts correspondants 36, 37 des charnières de la porte.The embedding of the reinforcements 34, 35 in the respective crosspieces 25, 24 makes it possible to stiffen the junctions between the upright 22 and the crosspieces 25, 24 and to bring the corresponding reinforcements 36, 37 of the door hinges.

Les renforts 34, 35 des charnières assurent également la rigidité de la liaison du cadre 30 avec les bords du montant 22 et des traverses 25, 24.The reinforcements 34, 35 of the hinges also ensure the rigidity of the connection of the frame 30 with the edges of the upright 22 and of the crosspieces 25, 24.

Selon une autre caractéristique du cadre renfort 30 représenté à la figure 5, sa membrure verticale 31 possède une partie découpée pliée 38 qui constitue le support de montage 39 d'un élément 40 arrêt-de-porte rigidement soudé à la porte.According to another characteristic of the reinforcement frame 30 shown in Figure 5, its vertical member 31 has a folded cut portion 38 which constitutes the mounting support 39 of a door stop element 40 rigidly welded to the door.

A cet effet, le support de montage 39 possède une extension axiale 41 soudée sur la paroi de fond 42 du montant avant 22 de l'ossature 2.To this end, the mounting support 39 has an axial extension 41 welded to the bottom wall 42 of the front upright 22 of the frame 2.

La traverse oblique 25 fermée par la membrure 33 constitue alors un élément de transfert des efforts entre le renfort de charnière 36 et un longeron latéral de la carrosserie à la suite d'une contrainte longitudinale exercée sur le logement d'une jambe de force de la suspension d'une roue du véhicule.The oblique cross 25 closed by the frame 33 then constitutes a force transfer element between the hinge reinforcement 36 and a lateral spar of the bodywork following a longitudinal stress exerted on the housing of a strut of the suspension of a vehicle wheel.

De manière analogue la traverse horizontale 24 fermée par la membrure 32 constitue un élément de transfert des efforts entre le renfort de charnière 37 et le longeron latéral de la carrosserie, à la suite d'une contrainte longitudinale exercée sur la roue du véhicule. Similarly, the horizontal crosspiece 24 closed by the frame 32 constitutes a force transfer element between the hinge reinforcement 37 and the lateral spar of the bodywork, following a longitudinal stress exerted on the vehicle wheel.
