Description

Porte de véhicule automobile renforcée à l'égard des chocs latéraux.Reinforced motor vehicle door with regard to side impacts.
La présente invention concerne une porte de véhicule renforcée à l'égard des chocs latéraux. On sait que les portes de véhicules automobiles comprennent classiquement un panneau extérieur et un panneau intérieur de caisson reliés entre eux à leur partie inférieure par une paroi de bas de porte s'étendant transversalement par rapport aux deux panneaux.The present invention relates to a vehicle door reinforced against side impacts. It is known that motor vehicle doors conventionally comprise an outer panel and an inner box panel interconnected at their lower part by a door bottom wall extending transversely with respect to the two panels.
Ces portes offrent une résistance relativement faible à l'égard des chocs latéraux.These doors offer a relatively low resistance to side impacts.
Pour remédier à cet inconvénient, les portes de véhicules automobiles sont souvent renforcées par des barres de renfort s'étendant derrière le panneau extérieur de la porte et situées pratiquement à mi-hauteur de la porte. Cependant, ces barres de renfort sont insuffisantes pour empêcher l'ouverture de la porte vers l'intérieur du véhicule, lors d'un choc latéral à une vitesse inférieure à 60 km/h.To overcome this disadvantage, motor vehicle doors are often reinforced by reinforcing bars extending behind the outer panel of the door and located substantially halfway up the door. However, these reinforcement bars are insufficient to prevent the door from opening towards the inside of the vehicle, during a side impact at a speed of less than 60 km / h.
Cette ouverture de la porte vers l'intérieur du véhicule est préjudiciable à l'égard des passagers. Cette ouverture est due à une trop faible résistance de la partie inférieure de la porte située sous les barres de renfort précitées. En effet, cette trop faible résistance permet à celle-ci de se déformer en passant au-dessus de la feuillure du caisson de bas de caisse du véhicule. La partie inférieure de la porte n'étant plus retenue par cette feuillure, la porte peut s'ouvrir vers l'intérieur, en blessant gravement, voire en tuant, les passagers.This opening of the door towards the interior of the vehicle is detrimental to the passengers. This opening is due to too low resistance of the lower part of the door located under the aforementioned reinforcement bars. Indeed, this too low resistance allows it to deform by passing over the rabbet of the subwoofer of the vehicle. The lower part of the door is no longer retained by this rabbet, the door can open inwards, seriously injuring or even killing passengers.
Le but de la présente invention est de remédier à cet inconvénient en renforçant la partie inférieure des portes de véhicules automobiles.The object of the present invention is to overcome this disadvantage by reinforcing the lower part of the doors of motor vehicles.
Suivant l'invention, la porte de véhicule automobile comprenant un panneau extérieur et un panneau intérieur de caisson reliés entre eux à leur partie inférieure par une paroi de bas de porte s'étendant transversalement par rapport aux deux panneaux, est caractérisée en ce que ladite paroi de bas de porte est renforcée par un élément de renfort fixé à cette paroi et s'étendant suivant une partie prépondérante de la longueur et de la largeur de cette paroi. Selon une version de l'invention, ledit élément de renfort est constitué par au moins une plaque métallique présentant une épaisseur plus importante que celle de ladite paroi de bas de porte.According to the invention, the motor vehicle door comprising an outer panel and an inner box panel interconnected at their lower part by a door bottom wall extending transversely with respect to the two panels, is characterized in that said door bottom wall is reinforced by a reinforcing element fixed to this wall and extending along a preponderant part of the length and width of this wall. According to one version of the invention, said reinforcing element is constituted by at least one metal plate having a greater thickness than that of said bottom door wall.
Dans un premier mode de réalisation de l'invention, ledit élément de renfort est une plaque métallique dont l'un des bords longitudinaux est fixé contre la face interne du panneau intérieur de caisson et dont l'autre bord longitudinal est fixé contre la face interne de la paroi de bas de porte, près du panneau extérieur.In a first embodiment of the invention, said reinforcing element is a metal plate one of whose longitudinal edges is fixed against the inner face of the inner box panel and whose other longitudinal edge is fixed against the inner face. the bottom wall of the door, near the outer panel.
De préférence, ladite plaque forme un angle aigu avec le panneau intérieur de caisson et avec la paroi du bas de porte et présente, sur chacun de ses bords longitudinaux, une bordure pliée parallèlement à la paroi à laquelle elle est fixée.Preferably, said plate forms an acute angle with the inner box panel and with the wall of the door bottom and has, on each of its longitudinal edges, a folded edge parallel to the wall to which it is attached.
Les essais ont montré que cette plaque empêchait l'ouverture de la porte vers l'intérieur en cas de chocs latéraux engendrés à des vitesses moyennes.Tests have shown that this plate prevents the opening of the door inwards in the event of side impacts generated at average speeds.
Dans un second mode de réalisation de l'invention, ledit élément de renfort comprend au moins une barre fixée contre la face extérieure de la paroi de bas de porte.In a second embodiment of the invention, said reinforcing element comprises at least one bar fixed against the outer face of the door bottom wall.
Selon d'autres particularités de ce second mode de réalisation : - ladite barre est fixée dans un renfoncement embouti dans ladite paroi de bas de porte, de façon que la face extérieure de ladite barre soit située sensiblement dans le prolongement de la partie de la paroi de bas de porte située à l'extérieur dudit renfoncement ; l'un des bords longitudinaux de la barre est situé sensiblement dans le prolongement de la paroi interne de caisson, de façon à être situé en regard de la feuillure formée dans le caisson du bas de caisse du véhicule, lorsque la porte est fermée. De préférence, ledit bord longitudinal présente une section transversale en forme de pointe adaptée pour pouvoir s'enfoncer dans la feuillure adjacente du bas de caisse en cas de choc latéral sur la porte.According to other features of this second embodiment: - said bar is fixed in a recess stamped in said bottom door wall, so that the outer face of said bar is located substantially in the extension of the wall portion lower door located outside said recess; one of the longitudinal edges of the bar is located substantially in the extension of the inner casing wall, so as to be located opposite the rabbet formed in the subwoofer box of the vehicle, when the door is closed. Preferably, said longitudinal edge has a peak-shaped cross-section adapted to be able to sink into the adjacent rebate of the sill in the event of a side impact on the door.
Cette disposition apporte une protection accrue en cas de choc latéral, en réduisant encore davantage les risques d'ouverture de la porte vers l'intérieur du véhicule.This provision provides increased protection in case of side impact, further reducing the risk of opening the door to the interior of the vehicle.
Dans une réalisation encore plus préférée de l'invention, le bas de la porte est renforcé à la fois par au moins une plaque du type décrit ci- dessus et par au moins une barre telle que décrite plus haut. D'autres particularités et avantages de l'invention apparaîtront encore dans la description ci-après.In an even more preferred embodiment of the invention, the bottom of the door is reinforced both by at least one plate of the type described above and by at least one bar as described above. Other features and advantages of the invention will become apparent in the description below.
Aux dessins annexés, donnés à titre d'exemples non limitatifs : la figure 1 est une vue en perspective d'une porte de véhicule automobile dont le panneau extérieur a été enlevé, montrant un élément de renfort de la paroi du bas de porte, la figure 2 est une vue en coupe transversale d'une porte de véhicule automobile comportant l'élément de renfort et du caisson de bas de caisse du véhicule, - la figure 3 est une vue analogue à la figure 2, montrant la déformation de la porte sous l'effet d'un choc latéral, la figure 4 est une vue en coupe transversale d'une porte et du caisson de bas de caisse d'un véhicule, la paroi du bas de porte étant renforcée par une barre, - la figure 5 est une vue de la face interne d'une porte et de la paroi du bas de porte renforcée par deux barres.In the accompanying drawings, given by way of nonlimiting example: FIG. 1 is a perspective view of a motor vehicle door whose outer panel has been removed, showing a reinforcing element of the wall of the door bottom, the FIG. 2 is a cross-sectional view of a motor vehicle door comprising the reinforcement element and the vehicle sill box, and FIG. 3 is a view similar to FIG. 2, showing the deformation of the door. under the effect of a side impact, Figure 4 is a cross-sectional view of a door and the sill box of a vehicle, the wall of the door bottom being reinforced by a bar, - the figure 5 is a view of the inner face of a door and the wall of the door bottom reinforced by two bars.
Dans la réalisation représentée sur les figures 1 et 2, la porte de véhicule automobile comprend un panneau extérieur 1 (enlevé sur la figure 1) et un panneau intérieur de caisson 2 reliés entre eux à leur partie inférieure par une paroi de bas de porte 3 s'étendant transversalement par rapport aux deux panneaux 1 , 2. Selon l'invention, ladite paroi de bas de porte 3 est renforcée par un élément de renfort 4 fixé à cette paroi 3 et s'étendant suivant une partie prépondérante de la longueur et de la largeur de cette paroi 3, en recouvrant la zone centrale de celle-ci.In the embodiment shown in Figures 1 and 2, the motor vehicle door comprises an outer panel 1 (removed in Figure 1) and an inner panel of box 2 connected to each other at their lower part by a door bottom wall 3 extending transversely with respect to the two panels 1, 2. According to the invention, said door bottom wall 3 is reinforced by a reinforcing element 4 fixed to this wall 3 and extending along a predominant part of the length and the width of this wall 3, covering the central area thereof.
Cet élément de renfort 4 est constitué, dans cet exemple, par une plaque métallique, par exemple en acier ou en aluminium, présentant de préférence une épaisseur plus importante que celle de la paroi de bas de porte 3. Comme montré par les figures 1 et 2 et notamment la figure 2, l'élément de renfort 4 est une plaque métallique dont l'un 4a des bords longitudinaux est fixé, de préférence par soudage, contre la face interne du panneau intérieur de caisson 2 et dont l'autre bord longitudinal 4b est fixé de la même manière contre la face interne de la paroi de bas de porte 3, près du panneau extérieur 1.This reinforcing element 4 consists, in this example, of a metal plate, for example of steel or aluminum, preferably having a greater thickness than that of the door bottom wall 3. As shown in FIGS. 2 and in particular FIG. 2, the reinforcing element 4 is a metal plate one of which 4a of the longitudinal edges is fixed, preferably by welding, against the inner face of the inner panel of caisson 2 and whose other longitudinal edge 4b is fixed in the same way against the inner face of the bottom wall of the door 3, near the outer panel 1.
Dans l'exemple représenté sur la figure 2, la plaque 4 forme un angle aigu avec le panneau intérieur de caisson 2 et avec la paroi du bas de porte 3 et présente, sur chacun de ses bords longitudinaux, une bordure pliée parallèlement à la paroi 2 ou 3 à laquelle elle est fixée. La plaque 4 forme ainsi une équerre qui renforce la partie inférieure de la porte. La figure 3 montre la déformation subie par un choc latéral appliqué par une barrière 5 se déplaçant à une vitesse de l'ordre de 60 km/h.In the example shown in FIG. 2, the plate 4 forms an acute angle with the inner panel of box 2 and with the wall of the door bottom 3 and has, on each of its longitudinal edges, a folded edge parallel to the wall 2 or 3 to which it is fixed. The plate 4 thus forms a bracket which reinforces the lower part of the door. Figure 3 shows the deformation experienced by a side impact applied by a barrier 5 moving at a speed of the order of 60 km / h.
Cette barrière 5 se déplace au-dessus du caisson de bas de caisse 6 du véhicule et notamment au-dessus de la feuillure 7 qui est en regard de la partie inférieure 2a de la paroi de caisson 2 de la porte.This barrier 5 moves above the sill box 6 of the vehicle and in particular above the rabbet 7 which is opposite the lower part 2a of the box wall 2 of the door.
On voit sur la figure 3 que la porte et le caisson 6 de bas de caisse sont plies vers l'intérieur du véhicule mais la partie inférieure 2a de la paroi de caisson 2 de la porte reste appliquée contre la feuillure 7. La porte ne s'est pas ouverte. Ce résultat s'explique par la présence de la plaque de renfort 4 qui augmente significativement la résistance de la partie inférieure de la porte à l'égard de la déformation engendrée en cas de choc latéral.It can be seen in FIG. 3 that the door and the sill box 6 are folded towards the inside of the vehicle but the lower part 2a of the box wall 2 of the door remains applied against the rebate 7. The door is not open. This result is explained by the presence of the reinforcing plate 4 which significantly increases the resistance of the lower part of the door with respect to the deformation generated in case of side impact.
Dans la réalisation représentée sur les figures 4 et 5, l'élément de renfort comprend deux barres métalliques 8 fixées, au moyen de vis 9, contre la face extérieure de la paroi de bas de porte 3.In the embodiment shown in FIGS. 4 and 5, the reinforcing element comprises two metal bars 8 fixed, by means of screws 9, against the outer face of the door bottom wall 3.
Dans cet exemple, les barres 8 sont fixées dans un renfoncement 10 embouti dans la paroi de bas de porte 3, de façon que la face extérieure 8a des barres 8 soit située sensiblement dans le prolongement de la partie 3a de la paroi de bas de porte 3 située à l'extérieur du renfoncement 10.In this example, the bars 8 are fixed in a recess 10 embossed in the door bottom wall 3, so that the outer face 8a of the bars 8 is located substantially in the extension of the portion 3a of the door bottom wall 3 located outside the recess 10.
Par ailleurs, l'un 8b des bords longitudinaux des barres 8 est situé sensiblement dans le prolongement de la partie inférieure 2a de la paroi interne de caisson 2, de façon à être situé en regard de la partie inférieure de la feuillure 7 formée dans le caisson du bas de caisse 6 du véhicule, lorsque la porte est fermée.Furthermore, one 8b of the longitudinal edges of the bars 8 is located substantially in the extension of the lower portion 2a of the inner casing wall 2, so as to be located facing the lower part of the rabbet 7 formed in the body of the sill 6 of the vehicle, when the door is closed.
En outre, le bord longitudinal 8b des barres 8 présente une section transversale en forme de pointe 8c adaptée pour pouvoir s'enfoncer dans la feuillure adjacente 7 du bas de caisse 6 en cas de choc latéral sur la porte. Dans l'exemple représenté sur la figure 4, la partie inférieure de la porte comporte non seulement les barres de renfort 8, mais également la plaque de renfort 4 décrite en référence aux figures 1 à 3. La présence simultanée de la plaque de renfort 4 et des barres 8 confère à la partie inférieure de la porte une résistance accrue à l'égard des chocs latéraux.In addition, the longitudinal edge 8b of the bars 8 has a tip-shaped cross section 8c adapted to be able to sink into the adjacent rebate 7 of the rocker 6 in case of side impact on the door. In the example shown in FIG. 4, the lower part of the door comprises not only the reinforcing bars 8, but also the reinforcing plate 4 described with reference to FIGS. 1 to 3. The simultaneous presence of the reinforcing plate 4 and the bars 8 gives the lower part of the door an increased resistance against side impacts.
En cas de choc latéral, l'arête pointue 8c des barres 8 se fiche dans la feuillure, ce qui évite encore davantage le risque d'ouverture de la porte vers l'intérieur du véhicule.In the event of a side impact, the sharp edge 8c of the bars 8 is plugged into the rabbet, which further avoids the risk of opening the door towards the interior of the vehicle.
Le double renforcement ci-dessus convient en particulier pour les véhicules à deux portes présentant chacune une longueur relativement importante, c'est-à-dire sensible aux chocs latéraux, comme dans le cas des coupés. The double reinforcement above is particularly suitable for vehicles with two doors each having a relatively large length, that is to say, sensitive to side impacts, as in the case of coupes.
