Description

SYSTEME DE MONTAGE ETANCHE DU PIED CENTRAL DE LA CAISSE D'UN VEHICULE AUTOMOBILE SUR LE LONGERON DU SOUBASSEMENT La présente invention concerne un système de montage étanche du pied central de la caisse d'un véhicule automobile sur le longeron du soubassement. La face supérieure du longeron comporte une feuillure définie par deux bordures de tôle soudées par points l'une à l'autre. The present invention relates to a waterproof mounting system of the central foot of the body of a motor vehicle on the underside of the base. The upper face of the spar has a rabbet defined by two edges of sheet metal welded by points to each other.

Cette soudure ne permet pas de réaliser l'étanchéité de la feuillure de sorte que du bruit et la poussière sont transmis dans la cavité du pied central, ce qui nuit à l'agrément des utilisateurs. La cavité du pied central sert de logement pour l'enrouleur de la ceinture de sécurité. This weld does not make it possible to seal the rabbet so that noise and dust are transmitted into the cavity of the central foot, which is detrimental to the approval of users. The central foot cavity serves as a seat for the seat belt retractor.

La cavité de l'enrouleur de la ceinture de sécurité est le plus souvent rendue étanche, en injectant de la mousse dans cette cavité après montage du pied central. Cependant, cette opération est délicate en raison de la mauvaise ergonomie de position de l'opérateur et la médiocre accessibilité de la cavité. The cavity of the seat belt retractor is most often sealed, by injecting foam into this cavity after mounting the central foot. However, this operation is difficult because of the poor ergonomics of the operator's position and the poor accessibility of the cavity.

De plus, cette mousse peut avoir été oubliée par erreur. Dans tous les cas cette opération est coûteuse, en matière et en main d'oeuvre et elle n'apporte pas de solution à l'étanchéité de la feuillure du longeron. Le but de la présente invention est de remédier aux inconvénients ci-dessus. L'invention vise ainsi un système de montage étanche du pied central de la caisse d'un véhicule automobile sur le longeron du soubassement, la partie supérieure de ce longeron comportant une feuillure définie par deux bordures de tôle soudées l'une contre l'autre, le pied central comportant un renfort inférieur en tôle emboutie dont la base porte une partie qui recouvre la face latérale intérieure du longeron et deux bords opposés qui se raccordent à la face supérieure du longeron et s'étendent transversalement entre la feuillure et la face latérale intérieure du longeron. Dans un système de montage de ce type, le but de l'invention est atteint grâce au fait qu'entre la base du renfort inférieur du pied central et la face supérieure du longeron est disposé un insert gonflant composé d'une matière qui 2 est capable de gonfler à partir d'une température prédéterminée pour réaliser l'étanchéité entre la base dudit renfort et le longeron. Cet insert est facile à manipuler car il est disposé sur la face supérieure du longeron avant le montage du pied central. In addition, this foam may have been forgotten by mistake. In all cases, this operation is costly, in terms of material and labor, and it does not provide a solution to the tightness of the groove of the spar. The object of the present invention is to overcome the above disadvantages. The invention thus relates to a sealed mounting system of the central foot of the body of a motor vehicle on the spar of the base, the upper part of this spar comprising a rabbet defined by two edges of sheet welded against each other , the central leg having a lower sheet metal reinforcement whose base carries a portion which covers the inner side face of the spar and two opposite edges which are connected to the upper face of the spar and extend transversely between the rabbet and the side face inside the spar. In a mounting system of this type, the object of the invention is achieved by the fact that between the base of the lower reinforcement of the central foot and the upper face of the spar is disposed a swelling insert composed of a material which 2 is capable of inflating from a predetermined temperature to seal between the base of said reinforcement and the spar. This insert is easy to handle because it is arranged on the upper face of the spar before mounting the central foot.

L'étanchéité entre la base du renfort inférieur du pied central, le longeron et la feuillure de celui-ci est ainsi obtenue avec un faible coût de matière et de main d'oeuvre. De préférence, ledit insert gonflant est fixé sur la face supérieure du longeron. io Cette fixation permet de garantir une position optimale de l'insert gonflant sur le longeron. Dans une version avantageuse de l'invention, l'insert gonflant comporte un support en matière rigide muni de doigts en saillie encliquetés dans des trous pratiqués dans la face supérieure du longeron. 15 Ce mode de fixation est de mise en oeuvre facile et permet d'obtenir une fixation précise de l'insert sur le longeron et dont la position ne risque pas d'être modifiée lors des opérations ultérieures de montage du pied central. De préférence, l'insert gonflant présente la forme d'un cadre rectangulaire dont le contour suit celui de la base du renfort. 20 Du fait de cette forme, l'insert peut être manipulé facilement comme une pièce de fabrication. Dans ce mode de réalisation, l'un des brins longitudinaux du cadre s'étend le long de la feuillure du longeron sur le côté opposé à la face latérale intérieure du longeron, les deux brins transversaux du cadre traversant chacun une encoche 25 pratiquée dans la feuillure et s'étendant entre la face supérieure du longeron et l'un desdits bords opposés du renfort, le second brin longitudinal du cadre s'étendant le long du bord supérieur de la face latérale du longeron et la face intérieure du renfort. Cette disposition permet de réaliser simultanément l'étanchéité de la feuillure 30 et de la cavité intérieure du pied central. 3 De préférence, le cadre comporte un brin transversal reliant les deux brins longitudinaux sensiblement au milieu de ceux-ci, ce brin transversal traversant une encoche pratiquée dans la feuillure. Ce brin transversal s'étendant au milieu du cadre permet notamment de renforcer la tenue mécanique du cadre, ce qui facilite sa manipulation. Dans un mode de réalisation encore plus avantageux, chacun des deux brins transversaux du cadre est relié audit second brin longitudinal par un brin oblique. Habituellement le pied central comporte une doublure en tôle emboutie dont la partie inférieure recouvre le renfort inférieur du pied central. io Selon une particularité avantageuse de l'invention, un moyen d'étanchéité est prévu entre le renfort inférieur et la doublure. De préférence, ledit moyen d'étanchéité est un insert gonflant de forme linéaire comportant un support rigide fixé sur la surface extérieure du renfort inférieur. 15 Cet insert gonflant peut être remplacé dans certains cas par un cordon de matière d'étanchéité telle que du mastic classique. L'insert gonflant ou le cordon ci-dessus s'étend de préférence sensiblement au niveau du bord supérieur de la face latérale intérieure du longeron. D'autres particularités et avantages de l'invention apparaîtront encore tout au 20 long de la description ci-après. Aux dessins annexés, donnés à titre d'exemples, non limitatifs : - la figure 1 est une vue en perspective montrant partiellement un renfort inférieur de pied central fixé sur la face supérieure d'un longeron, - la figure 2 est une vue analogue à la figure 1 montrant le montage étanche 25 réalisé grâce à un insert gonflant disposé entre le longeron et le pied central, - la figure 3 est une vue montrant l'insert gonflant disposé sur le longeron avant montage du renfort inférieur du pied central, - la figure 4 est une vue en coupe partielle de l'insert gonflant montrant les 30 moyens de fixation de celui-ci sur le longeron, - la figure 5 est une vue analogue à la figure 3 après montage du renfort inférieur du pied central, 4 - la figure 6 est une vue en coupe transversale du longeron et de la partie inférieure d'un pied central montrant l'insert gonflant. La figure 1 représente un renfort de pied central 1 qui recouvre la partie inférieure d'un pied central 2 monté sur le longeron 3 du soubassement de la caisse d'un véhicule automobile. Le renfort de pied central 1 est évasé vers le longeron 3 dans la direction longitudinale X du véhicule. La partie supérieure du longeron 3 comporte une feuillure 4 définie par deux bordures de tôle 4a, 4b (voir figure 6) soudées par points l'une contre l'autre. io Le renfort inférieur 1 est en tôle emboutie et sa base porte (voir figures 5 et 6) une partie 5 qui recouvre la face latérale intérieure 6 du longeron 3 et deux bords opposés 1 a, 1 b qui se raccordent (voir figure 5) à la face supérieure 7 du longeron 3 et s'étendent transversalement entre la feuillure 4 et la face latérale intérieure 6 du longeron 3. 15 Le renfort de pied central 1 comporte également deux bords latéraux 8, 9 (voir figures 1, 2 et 5) qui sont situés sensiblement dans le prolongement de la feuillure 4. Conformément à l'invention, entre la base du renfort inférieur 1 du pied central et la face supérieure 7 du longeron 3 est disposé un insert gonflant 10 20 composé d'une matière qui est capable de gonfler à partir d'une température prédéterminée pour réaliser l'étanchéité entre la base du renfort 1 et le longeron 3. Cet insert gonflant 10 est fixé sur la face supérieure 7 du longeron 3 et comporte à cet effet (voir figure 3) un support 10a en matière plastique rigide muni de doigts en saillie tels que le doigt 11 encliquetés dans des trous, tels que le trou 25 12, pratiqués dans la face supérieure 7 du longeron 3. La matière 10b qui recouvre le support 10a a une composition en elle-même connue lui permettant de gonfler à une température par exemple supérieure à 100°C. Dans l'exemple représenté sur les figures 2 et 3, l'insert gonflant 10 présente 30 la forme d'un cadre rectangulaire dont le contour suit celui de la base du renfort 1. The seal between the base of the lower reinforcement of the central foot, the spar and the rabbet thereof is thus obtained with a low cost of material and manpower. Preferably, said swelling insert is fixed on the upper face of the spar. This attachment ensures an optimal position of the inflating insert on the spar. In an advantageous version of the invention, the inflating insert comprises a support made of rigid material provided with projecting fingers snapped into holes made in the upper face of the spar. This method of attachment is easy to implement and provides a precise attachment of the insert on the spar and whose position is not likely to be changed during subsequent operations of mounting the central foot. Preferably, the swelling insert has the shape of a rectangular frame whose contour follows that of the base of the reinforcement. Because of this shape, the insert can be easily handled as a workpiece. In this embodiment, one of the longitudinal strands of the frame extends along the groove of the spar on the side opposite to the inner side face of the spar, the two transverse strands of the frame each passing through a notch 25 formed in the rabbet and extending between the upper face of the spar and one of said opposite edges of the reinforcement, the second longitudinal strand of the frame extending along the upper edge of the side face of the spar and the inner face of the reinforcement. This arrangement makes it possible to simultaneously seal the rabbet 30 and the inner cavity of the central foot. Preferably, the frame comprises a transverse strand connecting the two longitudinal strands substantially in the middle thereof, this transverse strand passing through a notch made in the rabbet. This transverse strand extending in the middle of the frame allows in particular to strengthen the mechanical strength of the frame, which facilitates its handling. In an even more advantageous embodiment, each of the two transverse strands of the frame is connected to said second longitudinal strand by an oblique strand. Usually the central foot has a stamped sheet metal lining whose lower part covers the lower reinforcement of the central foot. According to an advantageous feature of the invention, a sealing means is provided between the lower reinforcement and the liner. Preferably, said sealing means is a linear form of inflating insert comprising a rigid support fixed on the outer surface of the lower reinforcement. This swelling insert may in some cases be replaced by a bead of sealing material such as conventional putty. The inflating insert or cord above preferably extends substantially at the upper edge of the inner side face of the spar. Other features and advantages of the invention will become apparent throughout the description hereinafter. In the accompanying drawings, given by way of nonlimiting example: FIG. 1 is a perspective view partially showing a lower central foot reinforcement fixed on the upper face of a spar, FIG. 2 is a view similar to FIG. FIG. 1 showing the sealed assembly 25 made by means of a swelling insert disposed between the spar and the central foot; FIG. 3 is a view showing the swelling insert disposed on the spar before mounting the lower reinforcement of the central foot, FIG. 4 is a fragmentary sectional view of the inflating insert showing the fastening means thereof to the spar; FIG. 5 is a view similar to FIG. 3 after mounting the lower reinforcement of the central foot; Figure 6 is a cross-sectional view of the spar and the lower portion of a central leg showing the swelling insert. Figure 1 shows a central foot reinforcement 1 which covers the lower part of a central leg 2 mounted on the spar 3 of the underbody of the body of a motor vehicle. The central foot reinforcement 1 is flared towards the spar 3 in the longitudinal direction X of the vehicle. The upper part of the spar 3 has a rabbet 4 defined by two edges of sheet metal 4a, 4b (see Figure 6) welded by points against each other. The lower reinforcement 1 is made of pressed sheet metal and its base carries (see FIGS. 5 and 6) a portion 5 which covers the inner lateral face 6 of the spar 3 and two opposite edges 1a, 1b which are connected (see FIG. 5). at the upper face 7 of the spar 3 and extend transversely between the rabbet 4 and the inner side face 6 of the spar 3. The central foot reinforcement 1 also has two lateral edges 8, 9 (see FIGS. 1, 2 and 5 ) which are located substantially in the extension of the rabbet 4. According to the invention, between the base of the lower reinforcement 1 of the central foot and the upper face 7 of the spar 3 is arranged a swelling insert 10 20 made of a material which is able to inflate from a predetermined temperature to achieve the seal between the base of the reinforcement 1 and the spar 3. This inflating insert 10 is fixed on the upper face 7 of the spar 3 and comprises for this purpose (see Figure 3 ) a support 10a rigid plastic material provided with protruding fingers such as the finger 11 snapped into holes, such as the hole 12, formed in the upper face 7 of the spar 3. The material 10b which covers the support 10a has a composition in it - Even known to allow it to swell at a temperature for example greater than 100 ° C. In the example shown in FIGS. 2 and 3, the inflating insert 10 has the shape of a rectangular frame whose contour follows that of the base of the reinforcement 1.

La figure 3 montre que l'un 13 des brins longitudinaux du cadre s'étend le long de la feuillure 4 du longeron 3 sur le côté opposé à la face latérale intérieure 6 du longeron 3. Les deux brins transversaux 14, 15 du cadre traversant chacun une encoche 5 16, 17 pratiquée dans la feuillure 4 et s'étendent chacun entre la face supérieure 7 du longeron 3 et l'un des bords opposés 1 a, 1 b du renfort 1 (voir figure 5). Le second brin longitudinal 18 du cadre s'étend le long du bord supérieur 6a de la face latérale 6 du longeron 3 et la face intérieure du renfort 1. Le cadre formé par l'insert gonflant 10 comporte un brin transversal 19 reliant io les deux brins longitudinaux 13, 18 sensiblement au milieu de ceux-ci. Ce brin transversal 19 traverse également une encoche 20 pratiquée dans la feuillure 4. Chacun des deux brins transversaux 14, 15 est relié à l'un 18 des brins longitudinaux par un brin oblique 21, 22.FIG. 3 shows that one of the longitudinal strands of the frame extends along the rabbet 4 of the spar 3 on the side opposite to the inner lateral face 6 of the spar 3. The two transverse strands 14 and 15 of the transverse frame each a notch 5 16, 17 made in the rabbet 4 and each extend between the upper face 7 of the spar 3 and one of the opposite edges 1a, 1b of the reinforcement 1 (see Figure 5). The second longitudinal strand 18 of the frame extends along the upper edge 6a of the lateral face 6 of the spar 3 and the inner face of the reinforcement 1. The frame formed by the swelling insert 10 comprises a transverse strand 19 connecting the two longitudinal strands 13, 18 substantially in the middle thereof. This transverse strand 19 also passes through a notch 20 made in the rabbet 4. Each of the two transverse strands 14, 15 is connected to one of the longitudinal strands 18 by an oblique strand 21, 22.

15 Dans l'exemple de la figure 6, le pied central comporte une doublure 23 en tôle emboutie dont la partie inférieure recouvre la partie 5 du renfort inférieur 1 et un moyen d'étanchéité 24 est prévu entre le renfort inférieur 1 et la doublure 23. Le moyen d'étanchéité 24 peut être un insert gonflant de forme linéaire comportant un support rigide fixé sur la surface extérieure du renfort inférieur 1, 20 par des organes d'encliquetage 25, comme montré sur la figure 5. Suivant le jeu existant entre le renfort 1 et la doublure 23, le moyen d'étanchéité 24 peut être un cordon de matière d'étanchéité, par exemple en mastic. Dans l'exemple montré sur les figures 5 et 6, le moyen d'étanchéité 24 25 s'étend sensiblement au niveau du bord supérieur de la face latérale 6 du longeron 3. Pour réaliser le montage étanche d'un pied central sur le longeron 3, il suffit de poser sur la face supérieure 7 du longeron l'insert gonflant 10, comme montré sur la figure 3, puis de fixer sur le longeron selon les méthodes connues, le pied 30 central avec son renfort inférieur 1 et sa doublure 23.In the example of FIG. 6, the central foot comprises a stamped sheet metal liner 23 whose lower part covers the part 5 of the lower reinforcement 1 and a sealing means 24 is provided between the lower reinforcement 1 and the liner 23. The sealing means 24 may be a linearly shaped swelling insert having a rigid support fixed to the outer surface of the lower reinforcement 1, 20 by snap-fasteners 25, as shown in FIG. the reinforcement 1 and the liner 23, the sealing means 24 may be a bead of sealing material, for example mastic. In the example shown in Figures 5 and 6, the sealing means 24 extends substantially at the upper edge of the side face 6 of the spar 3. To achieve the tight fitting of a central foot on the spar 3, it suffices to place on the upper face 7 of the spar the inflating insert 10, as shown in FIG. 3, then to fix on the spar according to the known methods, the central foot 30 with its lower reinforcement 1 and its lining 23 .

6 La pose de l'insert gonflant 10 sur le longeron 3 est une opération facile du fait que l'insert est d'une seule pièce et comporte un support rigide qui lui confère une certaine tenue mécanique. La position géométrique de l'insert 10 sur le longeron est définie d'une 5 manière très précise grâce aux doigts 11 engagés par encliquetage dans des trous pratiqués sur le longeron 3. Avant la pose de la doublure 23 on fixe sur le renfort 1 comme montré sur la figure 5, un second insert gonflant 24 ou on applique sur ce renfort un cordon de mastic. Io Après application des différentes couches de peinture sur la caisse du véhicule, le passage de celle-ci dans l'étuve de séchage a pour effet de chauffer la matière composant les inserts 10 et 24 et de provoquer le gonflement de cette matière. Le gonflement de cette matière permet de réaliser une étanchéité parfaite au 15 niveau de la feuillure 4, de la cavité Cl (voir figure 6) située à la base du pied central au-dessus du longeron 3 et de la cavité C2 comprise entre le renfort 1 et la doublure 23. 6 The installation of the inflating insert 10 on the spar 3 is an easy operation because the insert is in one piece and comprises a rigid support which gives it a certain mechanical strength. The geometric position of the insert 10 on the spar is defined in a very precise manner thanks to the fingers 11 engaged by snapping into holes made on the spar 3. Before the laying of the liner 23 is fixed on the reinforcement 1 as shown in FIG. 5, a second swelling insert 24 or a bead of mastic is applied to this reinforcement. After application of the different layers of paint on the vehicle body, the passage of the latter in the drying oven has the effect of heating the material constituting the inserts 10 and 24 and causing the swelling of this material. The swelling of this material makes it possible to achieve a perfect seal at the rabbet 4, the cavity C1 (see FIG. 6) situated at the base of the central foot above the spar 3 and the cavity C2 between the reinforcement. 1 and the liner 23.
