- the support structure 1 0 is here produced by assembling a tube 1 2 of generally rectangular section here extending over the entire length of the structure from its end 1 4 said driver to its other end 1 5 said passenger; from the conductive end 1 4 of the structure 1 0, the tube 1 2 has a rectangular section with rounded edges, over almost half the length of the structure 1 0, then, beyond a connection zone and up to 'at the passenger end 1 5, its section is larger, practically square.
- a tube is for example conveniently obtained by hydroforming at constant perimeter of a cylindrical tube. Such a hydroforming process is described in particular in document EP-A-0 294 034.
- a beam 1 1 in U is joined by welding to the tube 1 2 which is partially engaged between the wings of the U of the beam 1 1 in U, which extends from the end conductor 1 4, along the part of the tube 1 3 of smaller section, then connects to the part of the latter of larger section whose section is however smaller than that encompassed by the beam 1 1.
- a support structure 1 0 of high mechanical resistance is thus obtained, including in the area close to the conductive end which supports the steering column.
- the references 1 3 show examples of locations intended for fixing the equipment placed in line with the dashboard; these are generally holes with or without collars, with smooth edges or tapped.
- each end of the support structure 1 it has one (or more) pair (s) of transversely facing openings for the passage of fasteners, such as through screws, for fixing the structure support 1 0 to the frame of the vehicle body; on the side of the conductive end 1 4, two pairs of openings are provided, a couple openings 1 6 affecting the walls of the beam 1 1 and the tube 1 2, and a couple of openings 1 8 affecting the walls of the beam 1 1 alone; on the side of the passenger end 1 5, a single pair of openings 1 7 is provided; advantageously, all of these openings are oblong in shape to take account of any dispersions of the bodywork.
- the support structure 1 0 according to the invention comprises at each of its ends a plastic collapse stopper.
- Figures 5 and 6 show the plug only which corresponds to the conductive end 1 4 of the support structure 1 0; this stopper referenced 20 has a flat sole 24 from which two blocks 21 and 22 emerge here separated by a gap 23.
- each block 21, 22 has a through passage, respectively 26, 28, the section of which corresponds to that of the openings 1 6, 1 8; here, each passage 26, 28 is bordered by an oblong metal tube 27, 29 around which the blocks 21 and 22 are overmolded.
- the block 21 is adapted to be force-fitted into the tube 1 2 and the block 22 in the closed space of the beam 1 1 limited by the tube 1 2; the production of gadroons not shown on the peripheral surface of the blocks 21, 22 allows the peripheral surface of the blocks 21, 22 to slightly deform to adapt to the dimensional variations of these blocks and of the support structure 1 0 in which they are inserted;
- the oblong tube 27 has a length which corresponds to the distance internally separating the walls of the tube 1 2 defining the openings 1 6, and the oblong tube 29 has a length which corresponds to the distance internally separating the wings of the beam 1 1 in U ;

- the plug when the plug is force-fitted into the beam structure 1 0, it is integral with it and forms part of it integral of said structure, without requiring bonding or welding; when in place, as shown in Figure 7, the passages 26, 28 are perfectly in line with the transversely facing openings 1 6, 1 8 respectively, the plug 20 being positioned in the support structure 1 0 by the coming in abutment, against the end edge of the support structure 10, of the rim 25 defined by the sole 24 around the blocks 21, 22; it should be noted that the ends of the oblong tubes 27, 29 are then at the right, and almost in contact, of the walls of the tube 1 2 and of the beam 1 1 carrying the openings: consequently, these oblong tubes 27, 29 play the role of spacers preventing these walls from flaming during the tightening of the fixing members of the support structure 1 0 passing through the passages 26, 28; thanks to the invention, the oblong tubes are perfectly positioned and economically, without the need to use a template; moreover, the passages 26, 28 guide
- Figures 8 to 1 0 are respectively similar to Figures 5 to 7 which have just been described but correspond to the plug 30 adapted to the passenger end 1 5 of the support structure 1 0; the plug 30, all other things being equal with respect to the plug 20, only has a plastic block 31 made from a sole 34 defining a flange 35 around it, and only a single passage 36 bordered by an oblong tube 37; the block 31 is adapted to the section of the tube 1 2 to the right of the passenger end 1 5.
- the passages 26, 28, 36 are bordered by oblong tubes 27, 29, 37 respectively; according to a variant not shown, the oblong tubes are eliminated and the role of anti-collapse spacer is performed by the plastic itself which constitutes the plug (s); good results have been obtained using, as plastic, polypropylene, polyvinyl chloride, polyethylene.
- an anti-collapse plug such as the plugs described above, is used to attach, to the beam structure 1 0, end plates.
- the plug 40 is associated with an end flange 100; to do this, the plug 40, provided with a through passage 46, here of circular section, consists of a block 41 of plastic material overmolded around a metal stirrup 42 in general U shape having a core 43 and two wings 44 embedded in block 41; the wings 44 of the stirrup 42 extend outside the block 41 according to returns 45 extending here parallel to the core 43 and located in the same plane away from one another; it is by the returns 45 that the plug 40 is fixed to the flange 1 00, for example by welding points 47.
- the plug 40, equipped with the flange 1 00 can be introduced into the support structure 1 0 on the vehicle assembly area just before it is attached to the bodywork and the above drawbacks are avoided.
- Figures 14, 1 5 and 1 6 show a plug 50 similar to the plug 40 described above, but here the stirrup 42 is not molded by the block 51 of plastic; the latter carries at the periphery of three of its sides a groove 53 whose width corresponds to that of the stirrup 42; the U of the stirrup 42 takes place in the groove 53, thus overlapping the block 51, then is fixed to the flange 100; thanks to the groove 53, the block 51 is held laterally; it will also be noted that here the cross section of the plastic block 51 is of generally circular shape, the plug then being adapted to equip a support structure 10 with tubular section; it can be seen that the invention applies to any kind of structure, whatever its section.
- the through passage 46, or 56 extends parallel to the wings of the stirrup 53; according to a variant not shown, the through passage extends perpendicular to the wings of the stirrup, that is to say parallel to the core of said stirrup, in which case the wings of the stirrup are provided with openings for the outlet of the through passage 46, 56.
- the support structures such as the support structure 1 0, can be obtained by hydroforming; it is also possible to produce by this process the openings such as 1 6, 1 7 or 1 8: in this case, as we know, the material displaced to make these openings does not detach from the structure but remains attached to it the manner of a tongue extending inside perpendicular to the wall provided with the corresponding opening; in this case, it is advantageous to provide, in the plastic block, a lateral notch 54 visible in Figures 1 7, 1 8 to avoid these tabs when mounting the plug in the support structure.
- Figure 1 9 shows an end flange 1 00 in which there has been formed, by cutting and stamping, an anchor 61 on which we just overmold the plastic block, which avoids the use of a jumper .
- an anchor for the plastic block is made by two tabs 62 cut from the flange 1 00 and then folded.
- the plugs are advantageously force-fitted at the ends of the support structure; similar results are obtained by simply inserting the plugs into the ends of the support structure and temporarily holding them there using holding means such as screws, pins or the like, the final connection of the plug and of the structure being achieved by fixing the latter on the framework bodywork; of course, in this case, the plugs and the support structure are adapted to receive said holding means.

Description
"Structure de support creuse de forme allongée comportant un bouchon anti-effondrement et bouchon anti-effondrement pour une telle structure" "Hollow support structure of elongated shape comprising an anti-collapse plug and anti-collapse plug for such a structure"
La présente invention a pour objet une structure de support creuse de forme allongée destinée en particulier à supporter les équipements d'un véhicule automobile placés au droit de sa planche de bord.The present invention relates to a hollow support structure of elongated shape intended in particular to support the equipment of a motor vehicle placed in line with its dashboard.
Une telle structure de support est bien connue ; habituellement dénommée traverse, elle est métallique et disposée transversalement, par rapport à l'axe longitudinal du véhicule, à l'avant de l'habitacle du véhicule et permet de supporter les équipements tels que la colonne de direction, l'appareil de chauffage ou de climatisation, le (ou les) sac(s) gonflables, la planche de bord elle-même, ainsi que d'autres équipements.Such a support structure is well known; usually called cross member, it is metallic and arranged transversely, with respect to the longitudinal axis of the vehicle, at the front of the passenger compartment of the vehicle and makes it possible to support equipment such as the steering column, the heater or air conditioning, the airbag (s), the dashboard itself, as well as other equipment.
Les traverses sont généralement fixées à l'ossature de la carrosserie du véhicule au voisinage de leurs extrémités. Pour ce faire, des éléments sont rapportés à leurs extrémités, notamment par soudage, comme le montrent par exemple les documents EP-A-694 465 ou US-A-4 826 235 ouThe crosspieces are generally fixed to the frame of the vehicle body near their ends. To do this, elements are attached at their ends, in particular by welding, as shown for example in documents EP-A-694,465 or US-A-4,826,235 or
US-A-5 387 023. Une telle façon de procéder est coûteuse.US-A-5 387 023. Such a procedure is expensive.
Pour réduire ces coûts, on a proposé de fixer la traverse par des organes de fixation, tels que des vis traversantes, traversant directement de part en part la traverse ; malheureusement, il s'est avéré que souvent le serrage de ces organes de fixation conduisait à une déformation par effondrement de la structure creuse constituant la traverse ; pour éviter cet inconvénient, on a proposé de renforcer l'intérieur des extrémités de la traverse en y logeant une entretoise anti-effondrement métallique solidarisée à la traverse par soudage ; dès lors, on a perdu les avantages conférés par le mode de fixation, un tel renforcement étant onéreux.To reduce these costs, it has been proposed to fix the cross member by fixing members, such as through screws, passing directly through the cross member; unfortunately, it has been found that often the tightening of these fixing members leads to a deformation by collapse of the hollow structure constituting the cross-member; to avoid this drawback, it has been proposed to reinforce the interior of the ends of the cross member by accommodating therein a metal anti-collapse spacer secured to the cross member by welding; therefore, the advantages conferred by the method of attachment have been lost, such reinforcement being expensive.
On a proposé, notamment dans le document US-A-4 863 21 4, de placer, à l'intérieur d'une structure creuse de forme allongée, une pièce nervurée pour positionner et maintenir des tubes anti-effondrement en face d 'ouvertures ; plus précisément, la structure selon ce document est réalisée sous forme de deux coquilles : la pièce nervurée est mise en place dans une première coquille en tôle emboutie à laquelle elle est solidarisée, en y
soudant par exemple deux des tubes anti-effondrement, et sur cet ensemble ainsi constitué est soudée une seconde coquille pour réaliser la structure creuse.It has been proposed, in particular in document US-A-4,863,214, to place, inside a hollow structure of elongated shape, a ribbed part for positioning and maintaining anti-collapse tubes in front of openings ; more precisely, the structure according to this document is produced in the form of two shells: the ribbed part is put into place in a first shell of stamped sheet metal to which it is secured, welding for example two of the anti-collapse tubes, and on this assembly thus formed is welded a second shell to produce the hollow structure.
Comme on le voit, une telle structure est complexe, et donc coûteuse ; par ailleurs, la fixation de la structure par ses extrémités n'est nullement évoquée.As can be seen, such a structure is complex, and therefore expensive; moreover, the fixing of the structure by its ends is in no way mentioned.
La présente invention a pour objet une structure de support creuse de forme allongée destinée en particulier à supporter les équipements d'un véhicule automobile placés au droit de sa planche de bord, les extrémités de ladite structure comportant, d'une part, des ouvertures transversalement en regard pour le passage d'organes de fixation et, d'autre part, des moyens anti-effondrement, ladite structure de support étant à un prix de revient inférieur à celui des structures de support connues jusqu'ici.The present invention relates to a hollow support structure of elongated shape intended in particular to support the equipment of a motor vehicle placed in line with its dashboard, the ends of said structure comprising, on the one hand, transverse openings opposite for the passage of fasteners and, on the other hand, anti-collapse means, said support structure being at a cost price lower than that of support structures known hitherto.
Selon l'invention, une structure de support du genre ci-dessus est caractérisée par le fait que les moyens anti-effondrement sont constitués d'un bouchon en matière plastique introduit dans ladite structure de support, aux extrémités de celle-ci, ledit bouchon présentant un passage traversant aligné avec iesdites ouvertures.According to the invention, a support structure of the above kind is characterized in that the anti-collapse means consist of a plastic plug inserted in said support structure, at the ends thereof, said plug having a through passage aligned with said openings.
De préférence, les ouvertures et le passage traversant ont une section de forme oblongue.Preferably, the openings and the through passage have an oblong section.
Avantageusement, la surface intérieure d'une extrémité, ou des deux, de la structure de support creuse destinée(s) à recevoir un bouchon est munie de moyens permettant de faciliter la mise en correspondance du, ou des, passage(s) traversant(s) avec Iesdites ouvertures. Par exemple, la surface intérieure d 'une extrémité, ou des deux, de la structure de support creuse destinée(s) à recevoir un bouchon n'est pas une surface de révolution de sorte que l'on n'a pas à faire tourner le bouchon pour mettre en correspondance le passage traversant et les ouvertures.Advantageously, the interior surface of one or both ends of the hollow support structure intended to receive a plug is provided with means making it possible to facilitate the matching of the crossing passage (s) ( s) with said openings. For example, the interior surface of one or both ends of the hollow support structure for receiving a plug is not a surface of revolution so that one does not have to rotate the plug to match the through passage and the openings.
En variante, la surface intérieure d'une extrémité, ou des deux, de la structure de support creuse est une surface de révolution et comporte en bout une encoche apte à coopérer avec un relief ménagé à la surface extérieure du, ou des, bouchon(s) .
Avantageusement, le bouchon présente une semelle d 'où émerge au moins un bloc, ladite semelle débordant par rapport au bloc en sorte que périphériquement est défini un rebord transversal.As a variant, the interior surface of one or both ends of the hollow support structure is a surface of revolution and comprises at the end a notch capable of cooperating with a relief formed on the exterior surface of the plug (s) ( s). Advantageously, the plug has a sole from which at least one block emerges, said sole projecting with respect to the block so that a transverse rim is defined peripherally.
De préférence, le passage traversant est bordé par un tube métallique ; avantageusement, le bloc est surmoulé autour du tube métallique.Preferably, the through passage is bordered by a metal tube; advantageously, the block is molded around the metal tube.
De préférence, la section de la structure de support délimitant plusieurs espaces fermés, de la semelle émergent plusieurs blocs dont chacun est adapté à être monté dans l'un desdits espaces.Preferably, the section of the support structure delimiting several closed spaces, from the sole several blocks emerge, each of which is adapted to be mounted in one of said spaces.
Avantageusement, le bouchon est adapté à être introduit à force dans ladite structure.Advantageously, the plug is adapted to be forced into said structure.
De préférence, le bouchon est solidaire d'un flasque d'extrémité.Preferably, the plug is integral with an end flange.
Avantageusement, la solidarisation du bouchon au flasque d'extrémité est réalisée au moyen d'un étrier présentant des retours par lesquels il est assujetti au flasque d'extrémité, par exemple par soudage. De préférence, le bloc du bouchon présente une rainure dans laquelle prend place l'étrier en chevauchant le bloc ; en variante, le bloc du bouchon est surmoulé autour de l'étrier.Advantageously, the plug is secured to the end flange by means of a stirrup having returns by which it is secured to the end flange, for example by welding. Preferably, the block of the plug has a groove in which the stirrup takes place, overlapping the block; alternatively, the plug block is molded around the stirrup.
De préférence, l'étrier est en forme générale de U et le passage traversant du bloc du bouchon s'étend parallèlement aux ailes de l'étrier ; en variante, l'étrier est en forme générale de U et le passage traversant du bloc du bouchon s'étend perpendiculairement aux ailes de l'étrier qui sont munies d'ouvertures pour le débouché du passage traversant.Preferably, the stirrup is generally U-shaped and the through passage of the block of the plug extends parallel to the wings of the stirrup; alternatively, the stirrup is generally U-shaped and the through passage of the block of the plug extends perpendicular to the wings of the stirrup which are provided with openings for the outlet of the through passage.
En variante, à la place d'un étrier, le flasque d'extrémité présente un ancrage sur lequel est surmoulé le bloc du bouchon : l'ancrage est obtenu par découpe et emboutissage ; en variante, l'ancrage est obtenu par découpe et pliage de pattes.Alternatively, instead of a stirrup, the end flange has an anchor on which the block of the plug is molded: the anchoring is obtained by cutting and stamping; alternatively, the anchoring is obtained by cutting and folding tabs.
Lorsque les ouvertures de la structure sont obtenues par hydroformage, le bloc présente avantageusement une échancrure latérale permettant d'éviter, lors du montage du bouchon dans la structure, la languette résultant de l'opération d'hydroformage.When the openings of the structure are obtained by hydroforming, the block advantageously has a lateral notch making it possible to avoid, during the mounting of the plug in the structure, the tongue resulting from the hydroforming operation.
La présente invention a également pour objet un bouchon antieffondrement pour une structure de support creuse de forme allongée ; selon
l'invention, un bouchon anti-effondrement a les caractéristiques du bouchon anti-effondrement évoqué ci-dessus.The present invention also relates to an anti-collapse plug for a hollow support structure of elongated shape; according to the invention, an anti-collapse plug has the characteristics of the anti-collapse plug mentioned above.

En se reportant aux figures 1 à 4, on voit que la structure de support 1 0 est ici réalisée par l'assemblage d'un tube 1 2 de section ici globalement rectangulaire s'étendant sur toute la longueur de la structure depuis son extrémité 1 4 dite conducteur jusqu'à son autre extrémité 1 5 dite passager ; depuis l'extrémité conducteur 1 4 de la structure 1 0, le tube 1 2 a une section rectangulaire à bords arrondis, sur presque la moitié de la longueur de la structure 1 0, puis, au delà d'une zone de raccordement et jusqu'à l'extrémité passager 1 5, sa section est plus grande, pratiquement de forme carrée. Un tel tube est par exemple commodément obtenu par hydroformage à périmètre constant d'un tube cylindrique. Un tel procédé d'hydroformage est notamment décrit dans le document EP-A-0 294 034.Referring to Figures 1 to 4, it can be seen that the support structure 1 0 is here produced by assembling a tube 1 2 of generally rectangular section here extending over the entire length of the structure from its end 1 4 said driver to its other end 1 5 said passenger; from the conductive end 1 4 of the structure 1 0, the tube 1 2 has a rectangular section with rounded edges, over almost half the length of the structure 1 0, then, beyond a connection zone and up to 'at the passenger end 1 5, its section is larger, practically square. Such a tube is for example conveniently obtained by hydroforming at constant perimeter of a cylindrical tube. Such a hydroforming process is described in particular in document EP-A-0 294 034.
Du côté de l'extrémité conducteur 1 4, une poutre 1 1 en U est solidarisée par soudage au tube 1 2 qui est engagé partiellement entre les ailes du U de la poutre 1 1 en U, laquelle s'étend, depuis l'extrémité conducteur 1 4, le long de la partie du tube 1 3 de plus faible section, puis se raccorde à la partie de celui-ci de plus grande section dont la section est toutefois plus petite que celle englobée par la poutre 1 1 . On obtient ainsi une structure de support 1 0 de grande résistance mécanique y compris dans la zone proche de l'extrémité conducteur qui supporte la colonne de direction. Les repères 1 3 montrent des exemples d'emplacements destinés à la fixation des équipements placés au droit de la planche de bord ; ce sont généralement des trous avec ou sans collet, à bord lisse ou taraudés.On the side of the conductive end 1 4, a beam 1 1 in U is joined by welding to the tube 1 2 which is partially engaged between the wings of the U of the beam 1 1 in U, which extends from the end conductor 1 4, along the part of the tube 1 3 of smaller section, then connects to the part of the latter of larger section whose section is however smaller than that encompassed by the beam 1 1. A support structure 1 0 of high mechanical resistance is thus obtained, including in the area close to the conductive end which supports the steering column. The references 1 3 show examples of locations intended for fixing the equipment placed in line with the dashboard; these are generally holes with or without collars, with smooth edges or tapped.
A chaque extrémité de la structure de support 1 0, celle-ci présente un (ou des) couple(s) d'ouvertures transversalement en regard pour le passage d 'organes de fixation, tels que des vis traversantes, pour fixer la structure de support 1 0 à l'ossature de la carrosserie du véhicule ; du côté de l'extrémité conducteur 1 4, deux couples d'ouvertures sont prévus, un couple
d'ouvertures 1 6 affectant les parois de la poutre 1 1 et du tube 1 2, et un couple d 'ouvertures 1 8 affectant les parois de la poutre 1 1 seule ; du côté de l'extrémité passager 1 5, un seul couple d'ouvertures 1 7 est prévu ; avantageusement, toutes ces ouvertures sont de forme oblongue pour tenir compte des dispersions éventuelles de la carrosserie.At each end of the support structure 1 0, it has one (or more) pair (s) of transversely facing openings for the passage of fasteners, such as through screws, for fixing the structure support 1 0 to the frame of the vehicle body; on the side of the conductive end 1 4, two pairs of openings are provided, a couple openings 1 6 affecting the walls of the beam 1 1 and the tube 1 2, and a couple of openings 1 8 affecting the walls of the beam 1 1 alone; on the side of the passenger end 1 5, a single pair of openings 1 7 is provided; advantageously, all of these openings are oblong in shape to take account of any dispersions of the bodywork.
La structure de support 1 0 selon l'invention comporte à chacune de ses extrémités un bouchon anti-effondrement en matière plastique.The support structure 1 0 according to the invention comprises at each of its ends a plastic collapse stopper.
Les figures 5 et 6 montrent le bouchon seul qui correspond à l'extrémité conducteur 1 4 de la structure de support 1 0 ; ce bouchon référencé 20 présente une semelle 24 plane d'où émergent ici deux blocs 21 et 22 séparés par un interstice 23.Figures 5 and 6 show the plug only which corresponds to the conductive end 1 4 of the support structure 1 0; this stopper referenced 20 has a flat sole 24 from which two blocks 21 and 22 emerge here separated by a gap 23.
Ici, chaque bloc 21 , 22 présente un passage traversant, respectivement 26, 28, dont la section correspond à celles des ouvertures 1 6, 1 8 ; ici, chaque passage 26, 28 est bordé par un tube oblong métallique 27, 29 autour duquel les blocs 21 et 22 sont surmoulés. Le bloc 21 est adapté à être monté à force dans le tube 1 2 et le bloc 22 dans l'espace fermé de la poutre 1 1 limité par le tube 1 2 ; la réalisation de godrons non représentés sur la surface périphérique des blocs 21 , 22 permet à la surface périphérique des blocs 21 , 22 de légèrement se déformer pour s'adapter aux variations dimensionnelles de ces blocs et de la structure de support 1 0 dans laquelle ils sont insérés ; le tube oblong 27 a une longueur qui correspond à la distance séparant intérieurement les parois du tube 1 2 définissant les ouvertures 1 6, et le tube oblong 29 a une longueur qui correspond à la distance séparant intérieurement les ailes de la poutre 1 1 en U ; les deux blocs 21 , 22 ont bien entendu en commun la semelle 24 qui les relie, l'ensemble étant obtenu d'une seule pièce par moulage ; l'interstice 23 a une largeur qui correspond à l'épaisseur de la paroi du tube 1 2, située à l'intérieur de la poutre 1 1 , qu'il est adapté à recevoir. La semelle 24 déborde par rapport aux blocs 21 , 22 en sorte que périphériquement est défini un rebord transversal 25.Here, each block 21, 22 has a through passage, respectively 26, 28, the section of which corresponds to that of the openings 1 6, 1 8; here, each passage 26, 28 is bordered by an oblong metal tube 27, 29 around which the blocks 21 and 22 are overmolded. The block 21 is adapted to be force-fitted into the tube 1 2 and the block 22 in the closed space of the beam 1 1 limited by the tube 1 2; the production of gadroons not shown on the peripheral surface of the blocks 21, 22 allows the peripheral surface of the blocks 21, 22 to slightly deform to adapt to the dimensional variations of these blocks and of the support structure 1 0 in which they are inserted; the oblong tube 27 has a length which corresponds to the distance internally separating the walls of the tube 1 2 defining the openings 1 6, and the oblong tube 29 has a length which corresponds to the distance internally separating the wings of the beam 1 1 in U ; the two blocks 21, 22 have of course in common the sole 24 which connects them, the assembly being obtained in one piece by molding; the gap 23 has a width which corresponds to the thickness of the wall of the tube 1 2, located inside the beam 1 1, which it is adapted to receive. The sole 24 projects beyond the blocks 21, 22 so that a transverse edge 25 is defined peripherally.
Ainsi, comme on le comprend aisément, lorsque le bouchon est monté à force dans la structure de poutre 1 0, il en est solidaire et fait partie
intégrante de ladite structure, sans nécessiter de collage ou soudage ; lorsqu'il est en place, comme le montre la figure 7, les passages 26, 28 sont parfaitement au droit des ouvertures transversalement en regard 1 6, 1 8 respectivement, le bouchon 20 étant positionné dans la structure de support 1 0 par la venue en butée, contre le bord d'extrémité de la structure de support 1 0, du rebord 25 défini par la semelle 24 autour des blocs 21 , 22 ; il est à noter que les extrémités des tubes oblongs 27, 29 sont alors au droit, et quasiment au contact, des parois du tube 1 2 et de la poutre 1 1 portant les ouvertures : dès lors, ces tubes oblongs 27, 29 jouent le rôle d'entretoises empêchant ces parois de flamber lors du serrage des organes de fixation de la structure du support 1 0 traversant les passages 26, 28 ; grâce à l'invention, les tubes oblongs sont parfaitement positionnés et ce de manière économique, sans qu'il soit nécessaire d'utiliser un gabarit ; par ailleurs, les passages 26, 28 guident les organes de fixation lors du montage de la structure de support 1 0 sur l'ossature de la carrosserie.Thus, as is easily understood, when the plug is force-fitted into the beam structure 1 0, it is integral with it and forms part of it integral of said structure, without requiring bonding or welding; when in place, as shown in Figure 7, the passages 26, 28 are perfectly in line with the transversely facing openings 1 6, 1 8 respectively, the plug 20 being positioned in the support structure 1 0 by the coming in abutment, against the end edge of the support structure 10, of the rim 25 defined by the sole 24 around the blocks 21, 22; it should be noted that the ends of the oblong tubes 27, 29 are then at the right, and almost in contact, of the walls of the tube 1 2 and of the beam 1 1 carrying the openings: consequently, these oblong tubes 27, 29 play the role of spacers preventing these walls from flaming during the tightening of the fixing members of the support structure 1 0 passing through the passages 26, 28; thanks to the invention, the oblong tubes are perfectly positioned and economically, without the need to use a template; moreover, the passages 26, 28 guide the fastening members when the support structure 1 0 is mounted on the bodywork of the body.
Les figures 8 à 1 0 sont analogues respectivement aux figures 5 à 7 qui viennent d'être décrites mais correspondent au bouchon 30 adapté à l'extrémité passager 1 5 de la structure de support 1 0 ; le bouchon 30, toutes choses égales par ailleurs par rapport au bouchon 20, ne comporte qu'un bloc 31 en matière plastique issu d'une semelle 34 définissant un rebord 35 autour de celui-ci, et qu'un seul passage 36 bordé par un tube oblong 37 ; le bloc 31 est adapté à la section du tube 1 2 au droit de l'extrémité passager 1 5.Figures 8 to 1 0 are respectively similar to Figures 5 to 7 which have just been described but correspond to the plug 30 adapted to the passenger end 1 5 of the support structure 1 0; the plug 30, all other things being equal with respect to the plug 20, only has a plastic block 31 made from a sole 34 defining a flange 35 around it, and only a single passage 36 bordered by an oblong tube 37; the block 31 is adapted to the section of the tube 1 2 to the right of the passenger end 1 5.
Dans les exemples qui viennent d'être décrits, les passages 26, 28,36 sont bordés par des tubes oblongs 27,29,37 respectivement ; selon une variante non représentée, les tubes oblongs sont supprimés et le rôle d'entretoise anti-effondrement est réalisé par la matière plastique elle-même qui constitue le(s) bouchon(s) ; de bons résultats ont été obtenus en utilisant, comme matière plastique, du poiypropylène, du polychlorure de vinyle, du polyéthylène.
Selon un deuxième aspect de l'invention, un bouchon antieffondrement, tel que les bouchons décrits ci-dessus, est utilisé pour rapporter, sur la structure de poutre 1 0, des flasques d'extrémité.In the examples which have just been described, the passages 26, 28, 36 are bordered by oblong tubes 27, 29, 37 respectively; according to a variant not shown, the oblong tubes are eliminated and the role of anti-collapse spacer is performed by the plastic itself which constitutes the plug (s); good results have been obtained using, as plastic, polypropylene, polyvinyl chloride, polyethylene. According to a second aspect of the invention, an anti-collapse plug, such as the plugs described above, is used to attach, to the beam structure 1 0, end plates.
Plus précisément, il est en général prévu de solidariser à chaque bout de la structure de poutre un flasque disposé transversalement pour la fixation et/ou le maintien de la planche de bord elle-même, le contour desdits flasques étant adapté à la section de ladite planche, voire l'habillage de celle- ci.More specifically, provision is generally made to secure at each end of the beam structure a flange arranged transversely for fixing and / or maintaining the dashboard itself, the contour of said flanges being adapted to the section of said board, or even the covering of it.
Jusqu'ici, de tels flasques sont solidarisés par soudage à la structure de support. Outre le fait que cette opération est difficile et onéreuse, elle ne facilite pas le stockage ni le transport desdites structures ainsi équipées jusqu'à l'aire de montage des véhicules, d'autant plus que lesdits flasques peuvent être de grandes dimensions ; de plus, ceux-ci sont fragiles et peuvent se déformer lors du stockage ou du transport. Grâce à l'invention, ces inconvénients sont supprimés.So far, such flanges are secured by welding to the support structure. In addition to the fact that this operation is difficult and expensive, it does not facilitate the storage or the transportation of said structures thus equipped to the vehicle assembly area, all the more so since said flanges can be large; moreover, these are fragile and can deform during storage or transport. Thanks to the invention, these drawbacks are eliminated.
Selon les figures 1 1 à 1 3, le bouchon 40 est associé à un flasque d'extrémité 100 ; pour ce faire, le bouchon 40, muni d'un passage traversant 46, ici de section circulaire, est constitué d'un bloc 41 en matière plastique surmoulée autour d'un étrier métallique 42 en forme générale de U ayant une âme 43 et deux ailes 44 noyées dans le bloc 41 ; les ailes 44 de l'étrier 42 se prolongent à l'extérieur du bloc 41 selon des retours 45 s'étendant ici parallèlement à l'âme 43 et situés dans un même plan en s'éloignant l'un de l'autre ; c'est par les retours 45 que le bouchon 40 est fixé sur le flasque 1 00, par exemple par des points de soudage 47. Ainsi, le bouchon 40, équipé du flasque 1 00, peut être introduit dans la structure de support 1 0 sur l'aire de montage des véhicules juste avant la fixation de celle-ci sur l'ossature de carrosserie et les inconvénients ci-dessus sont évités.According to Figures 1 1 to 1 3, the plug 40 is associated with an end flange 100; to do this, the plug 40, provided with a through passage 46, here of circular section, consists of a block 41 of plastic material overmolded around a metal stirrup 42 in general U shape having a core 43 and two wings 44 embedded in block 41; the wings 44 of the stirrup 42 extend outside the block 41 according to returns 45 extending here parallel to the core 43 and located in the same plane away from one another; it is by the returns 45 that the plug 40 is fixed to the flange 1 00, for example by welding points 47. Thus, the plug 40, equipped with the flange 1 00, can be introduced into the support structure 1 0 on the vehicle assembly area just before it is attached to the bodywork and the above drawbacks are avoided.
Les figures 14, 1 5 et 1 6 montrent un bouchon 50 analogue au bouchon 40 décrit ci-dessus, mais ici l'étrier 42 n'est pas surmoulé par le bloc 51 en matière plastique ; celui-ci porte à la périphérie de trois de ses côtés une rainure 53 dont la largeur correspond à celle de l'étrier 42 ; le U de
l'étrier 42 prend place dans la rainure 53, chevauchant ainsi le bloc 51 , puis est fixé au flasque 100 ; grâce à la rainure 53, le bloc 51 est maintenu latéralement; on notera également qu'ici la section transversale du bloc 51 en matière plastique est de forme globalement circulaire, le bouchon étant alors adapté à équiper une structure de support 10 à section tubulaire ; on voit que l 'invention s'applique à toute sorte de structure, quelle que soit sa section.Figures 14, 1 5 and 1 6 show a plug 50 similar to the plug 40 described above, but here the stirrup 42 is not molded by the block 51 of plastic; the latter carries at the periphery of three of its sides a groove 53 whose width corresponds to that of the stirrup 42; the U of the stirrup 42 takes place in the groove 53, thus overlapping the block 51, then is fixed to the flange 100; thanks to the groove 53, the block 51 is held laterally; it will also be noted that here the cross section of the plastic block 51 is of generally circular shape, the plug then being adapted to equip a support structure 10 with tubular section; it can be seen that the invention applies to any kind of structure, whatever its section.
Dans les exemples décrits aux figures 1 1 à 1 6, le passage traversant 46, ou 56, s'étend parallèlement aux ailes de l'étrier 53 ; selon une variante non représentée, le passage traversant s'étend perpendiculairement aux ailes de l'étrier, c'est-à-dire parallèlement à l'âme dudit étrier, auquel cas les ailes de l'étrier sont munies d'ouvertures pour le débouché du passage traversant 46, 56.In the examples described in Figures 1 1 to 1 6, the through passage 46, or 56, extends parallel to the wings of the stirrup 53; according to a variant not shown, the through passage extends perpendicular to the wings of the stirrup, that is to say parallel to the core of said stirrup, in which case the wings of the stirrup are provided with openings for the outlet of the through passage 46, 56.
Les structures de support, telles que la structure de support 1 0, peuvent être obtenues par hydroformage ; il est possible également de réaliser par ce procédé les ouvertures telles que 1 6, 1 7 ou 1 8 : dans ce cas, comme on le sait, la matière déplacée pour réaliser ces ouvertures ne se détache pas de la structure mais y reste accrochée à la manière d'une languette s'étendant à l'intérieur perpendiculairement à la paroi munie de l'ouverture correspondante ; dans ce cas, il est avantageux de prévoir, dans le bloc en matière plastique, une échancrure latérale 54 visible sur les figures 1 7, 1 8 permettant d'éviter ces languettes lors du montage du bouchon dans la structure support.The support structures, such as the support structure 1 0, can be obtained by hydroforming; it is also possible to produce by this process the openings such as 1 6, 1 7 or 1 8: in this case, as we know, the material displaced to make these openings does not detach from the structure but remains attached to it the manner of a tongue extending inside perpendicular to the wall provided with the corresponding opening; in this case, it is advantageous to provide, in the plastic block, a lateral notch 54 visible in Figures 1 7, 1 8 to avoid these tabs when mounting the plug in the support structure.
La figure 1 9 montre un flasque d'extrémité 1 00 dans lequel on a ménagé, par découpe et emboutissage, un ancrage 61 sur lequel on vient surmouler le bloc en matière plastique, ce qui permet d'éviter l'utilisation d'un cavalier.Figure 1 9 shows an end flange 1 00 in which there has been formed, by cutting and stamping, an anchor 61 on which we just overmold the plastic block, which avoids the use of a jumper .
Selon la figure 20, un ancrage pour le bloc en matière plastique est réalisé par deux pattes 62 découpées dans le flasque 1 00 puis pliées. Dans tout ce qui précède, les bouchons sont avantageusement introduits à force aux extrémités de la structure de support ; des résultats analogues sont obtenus en introduisant simplement les bouchons aux
extrémités de la structure de support et en les y maintenant provisoirement à l'aide de moyens de maintien tels que vis, goupilles ou autres, la solidarisation définitive du bouchon et de la structure étant réalisée par la fixation de celle-ci sur l'ossature de carrosserie ; bien entendu, dans ce cas, les bouchons et la structure de support sont adaptés à recevoir lesdits moyens de maintien.
According to Figure 20, an anchor for the plastic block is made by two tabs 62 cut from the flange 1 00 and then folded. In all of the above, the plugs are advantageously force-fitted at the ends of the support structure; similar results are obtained by simply inserting the plugs into the ends of the support structure and temporarily holding them there using holding means such as screws, pins or the like, the final connection of the plug and of the structure being achieved by fixing the latter on the framework bodywork; of course, in this case, the plugs and the support structure are adapted to receive said holding means.
