Description

Titre : Ensemble de traverse de planche de bord pour véhicule comprenant deux portions longitudinales fixées ensemble au moyen d’un raccord de fixation Title: Dashboard crossmember assembly for a vehicle comprising two longitudinal portions fixed together by means of a fixing connector
Domaine technique Technical area
[0001] La présente invention est relative à un ensemble de traverse de planche de bord (ou CCB, de l’anglais « Cross Car Beam ») pour véhicule. L’invention se rapporte également à un ensemble de planche de bord pour véhicule, notamment pour véhicule automobile, comportant un tel ensemble de traverse. [0001] The present invention relates to a dashboard cross-member assembly (or CCB, from English “Cross Car Beam”) for a vehicle. The invention also relates to a dashboard assembly for a vehicle, in particular for a motor vehicle, comprising such a cross member assembly.
Technique antérieure Prior art
[0002] Dans le domaine automobile, un ensemble de traverse de planche de bord est connu, qui permet notamment de fixer la planche de bord à la caisse du véhicule automobile. Un tel ensemble de traverse de planche de bord peut également avoir une fonction de sécurité, par exemple en absorbant une partie de l’énergie en cas de choc frontal provoquant une déformation de la caisse, afin de limiter la déformation de la planche de bord. [0002] In the automotive field, a dashboard cross member assembly is known, which makes it possible in particular to fix the dashboard to the body of the motor vehicle. Such a dashboard crossmember assembly can also have a safety function, for example by absorbing part of the energy in the event of a frontal impact causing deformation of the body, in order to limit the deformation of the dashboard.
[0003] Classiquement, un tel ensemble de traverse de planche de bord est en métal. [0003] Conventionally, such a dashboard crosspiece assembly is made of metal.
[0004] Cependant, il est connu, par exemple de la demande EP-A-3 162 671 , un ensemble de traverse de planche de bord, dit « hybride », dont la traverse comporte une première portion longitudinale en un premier matériau, notamment en métal, et une deuxième portion longitudinale en un deuxième matériau, notamment en matériau composite. Un tel ensemble de traverse de planche de bord est notamment moins lourd qu’un ensemble de traverse de planche de bord identique, entièrement réalisé en métal. Des accessoires de la planche de bord sont fixés sur la première portion longitudinale et sur la deuxième portion longitudinale de la traverse. [0004] However, it is known, for example from application EP-A-3 162 671, a dashboard cross member assembly, called "hybrid", the cross member of which comprises a first longitudinal portion made of a first material, in particular made of metal, and a second longitudinal portion made of a second material, in particular a composite material. Such a dashboard cross member assembly is notably less heavy than an identical dashboard cross member assembly, made entirely of metal. Dashboard accessories are fixed on the first longitudinal portion and on the second longitudinal portion of the crossmember.
[0005] Selon ce document, la deuxième portion longitudinale est emmanchée dans la première portion longitudinale. De cette façon, la traverse obtenue présente une rigidité satisfaisante. [0005] According to this document, the second longitudinal portion is fitted into the first longitudinal portion. In this way, the crosspiece obtained has satisfactory rigidity.
[0006] Cependant, pour certaines applications, il peut être préférable que les portions longitudinales soient fixées ensemble de manière plus fiable et/ou résistante, de préférence en demeurant démontable. Le démontage des portions longitudinales l’une par rapport à l’autre peut notamment faciliter le recyclage des portions longitudinales, en particulier quand ces portions longitudinales sont en des matériaux différents. However, for certain applications, it may be preferable for the longitudinal portions to be fixed together in a more reliable and/or resistant manner, preferably while remaining removable. Dismantling the longitudinal portions from one another can in particular facilitate the recycling of the longitudinal portions, in particular when these longitudinal portions are made of different materials.
[0007] Par ailleurs, il est connu du brevet JP-B-4496592, un ensemble de traverse de planche de bord dont la traverse comprend deux portions métalliques extrudées, de sections transversales différentes, fixées ensemble au moyen d’un connecteur cylindrique, en métal, interposé entre les deux portions métalliques. Selon ce document, chaque portion métallique est fixée au connecteur à l’aide d’un moyen mécanique de fixation, tel qu’un boulon. [0007] Furthermore, it is known from patent JP-B-4496592, a dashboard cross member assembly whose cross member comprises two extruded metal portions, of different cross sections, fixed together by means of a cylindrical metal connector, interposed between the two metal portions. According to this document, each metal portion is fixed to the connector using a mechanical fixing means, such as a bolt.

Description d’exemples de réalisation Description of implementation examples
[0027] Sur les différentes figures, les mêmes références désignent des éléments identiques ou de fonction identique. Seules les différences entre les différents exemples présentés sont décrites en détail. [0027] In the different figures, the same references designate identical elements or identical functions. Only the differences between the different examples presented are described in detail.
[0028] Les figures 1 et 2 représentent un exemple d’ensemble de traverse de planche de bord 10 pour véhicule automobile. [0028] Figures 1 and 2 represent an example of a dashboard crossmember assembly 10 for a motor vehicle.
[0029] L’ensemble de traverse de planche de bord 10 est destiné à former un élément de structure de la planche de bord D du véhicule automobile V. L’ensemble de traverse de planche de bord 10 est notamment destinée à rigidifier la caisse BIW (ou caisse en blanc, de l’anglais « body in white ») du véhicule automobile V et/ou à supporter des équipements ou accessoires du véhicule automobile V, notamment la planche de bord D et/ou une colonne de direction et/ou des conduits d’air d’un système de chauffage, de ventilation et de climatisation HVAC (ou HVAC, pour l’anglais « Heating, Ventilation and Air- Conditioning ») de l’habitacle du véhicule automobile V et /ou un écran S et /ou une boîte à gants G et/ou un module de coussin gonflable de sécurité Ab et/ou un dispositif d’affichage tête haute H. The dashboard cross member assembly 10 is intended to form a structural element of the dashboard D of the motor vehicle V. The dashboard cross member assembly dashboard 10 is in particular intended to stiffen the BIW body (or body in white) of the motor vehicle V and/or to support equipment or accessories of the motor vehicle V, in particular the dashboard. edge D and/or a steering column and/or air ducts of an HVAC heating, ventilation and air conditioning system (or HVAC, for English “Heating, Ventilation and Air-Conditioning”) of the the passenger compartment of the motor vehicle V and/or a screen S and/or a glove box G and/or an airbag module Ab and/or a head-up display device H.
[0030] Tel qu’illustré, l’ensemble de traverse de planche de bord 10 comprend tout d’abord une traverse 12. La traverse 12 s’étend principalement selon un axe longitudinal A destiné à être orientée selon une direction transversale dans le véhicule automobile V. La traverse 12 est dite hybride en ce qu’elle comporte une première portion 14 longitudinale, en métal, et une deuxième portion 16 longitudinale, en matériau contenant du plastique. Par matériau contenant du plastique, on entend ici un matériau plastique, éventuellement chargé de fibres de renfort, notamment de fibres de verre. Ainsi, les matériaux contenant du plastique comprennent les plastiques et les matériaux composites. Le matériau dont est formé la deuxième portion longitudinale 16 de la traverse 12 comprend par exemple au moins 50 % en masse de fibres de verre ou de carbone, de préférence au moins 60 % en masse de fibres de verre ou de carbone. As illustrated, the dashboard cross member assembly 10 firstly comprises a cross member 12. The cross member 12 extends mainly along a longitudinal axis A intended to be oriented in a transverse direction in the vehicle automobile V. The crossmember 12 is called hybrid in that it comprises a first longitudinal portion 14, made of metal, and a second longitudinal portion 16, made of material containing plastic. By material containing plastic, we mean here a plastic material, possibly loaded with reinforcing fibers, in particular glass fibers. Thus, materials containing plastic include plastics and composite materials. The material from which the second longitudinal portion 16 of the crosspiece 12 is formed comprises for example at least 50% by mass of glass or carbon fibers, preferably at least 60% by mass of glass or carbon fibers.
[0031] Ici, les deux portions longitudinales 14, 16 s’étendent l’une à côté de l’autre dans la direction de l’axe A d’extension de la traverse 12. En d’autres termes, ici, une majorité de la longueur de la première portion longitudinale 14 et/ou une majorité de la longueur de la deuxième portion longitudinale 16 ne sont pas superposées, selon une direction perpendiculaire à la direction de l’axe A d’extension de la traverse 12. [0031] Here, the two longitudinal portions 14, 16 extend one next to the other in the direction of the axis A of extension of the crosspiece 12. In other words, here, a majority of the length of the first longitudinal portion 14 and/or a majority of the length of the second longitudinal portion 16 are not superimposed, in a direction perpendicular to the direction of the axis A of extension of the crosspiece 12.
[0032] Telle qu’illustrée, la première portion 14 est de forme sensiblement tubulaire. Ici la première portion 14 est de section sensiblement circulaire. Comme visible sur les figures 1 et 2, l’ensemble de traverse de planche de bord 10 comprend un support 17 de colonne de direction fixé sur la première portion 14. Notamment, le support de colonne de direction 17 peut être soudé sur la première portion 14. Il apparait en effet préférable qu’un tel support de colonne de direction 17 soit fixé sur une portion 14 de la traverse 12 en métal, ceci afin d’assurer une résistance satisfaisante en cas de choc, notamment de choc frontal. En d’autres termes, une telle configuration dans laquelle un support de colonne de direction 17 est fixé sur une portion en métal de la traverse 12 apparait préférable à des fins de sécurité du conducteur du véhicule automobile V. [0033] Par ailleurs, un dispositif 18 de fixation de la traverse 12 sur la caisse BIW du véhicule V, notamment au tablier Ta de la caisse BIW du véhicule automobile et/ou à la traverse inférieure de baie T de la caisse BIW du véhicule automobile V, peut être fixé sur la première portion longitudinale 14 de la traverse 12. Par exemple, comme cela est illustré, le dispositif de fixation 18 est disposé sensiblement au même niveau longitudinalement sur la première portion longitudinale 14 de la traverse 12, que le support de colonne de direction 17. As illustrated, the first portion 14 is of substantially tubular shape. Here the first portion 14 is of substantially circular section. As visible in Figures 1 and 2, the dashboard crossmember assembly 10 comprises a steering column support 17 fixed on the first portion 14. In particular, the steering column support 17 can be welded to the first portion 14. It in fact appears preferable for such a steering column support 17 to be fixed on a portion 14 of the metal crossmember 12, in order to ensure satisfactory resistance in the event of an impact, particularly a frontal impact. In other words, such a configuration in which a steering column support 17 is fixed on a metal portion of the crosspiece 12 appears preferable for safety purposes for the driver of the motor vehicle V. [0033] Furthermore, a device 18 for fixing the crossmember 12 to the BIW body of the vehicle V, in particular to the apron Ta of the BIW body of the motor vehicle and/or to the lower bay crossmember T of the BIW body of the vehicle automobile V, can be fixed on the first longitudinal portion 14 of the crosspiece 12. For example, as illustrated, the fixing device 18 is arranged substantially at the same level longitudinally on the first longitudinal portion 14 of the crosspiece 12, as the steering column support 17.
[0034] L’ensemble de traverse de planche de bord 10 comprend encore un premier étrier 20 fixé à une extrémité longitudinale de la première portion 14 de la traverse 12, formant une extrémité de la traverse 12. Le premier étrier 20 est par exemple emmanché en force et/ou vissé sur la première portion 14 de la traverse 12. Alternativement, le premier étrier 20 est par exemple soudé sur la première portion 14 de la traverse 12. Le premier étrier 20 est par exemple en matériau contenant du plastique ou en métal. Le premier étrier 20 permet de fixer l’ensemble de traverse de planche de bord 10 sur la caisse BIW du véhicule automobile V, par exemple à un premier montant A (de l’anglais « A-pillar») de la caisse BIW du véhicule automobile V. The dashboard cross member assembly 10 further comprises a first stirrup 20 fixed to a longitudinal end of the first portion 14 of the cross member 12, forming one end of the cross member 12. The first stirrup 20 is for example fitted in force and/or screwed onto the first portion 14 of the crosspiece 12. Alternatively, the first stirrup 20 is for example welded to the first portion 14 of the crosspiece 12. The first stirrup 20 is for example made of a material containing plastic or of metal. The first bracket 20 makes it possible to fix the dashboard cross member assembly 10 to the BIW body of the motor vehicle V, for example to a first A-pillar (from the English “A-pillar”) of the BIW body of the vehicle automobile V.
[0035] L’ensemble de traverse de planche de bord 10 comprend un deuxième étrier 22 de fixation de la traverse 12 sur la caisse BIW du véhicule automobile V. Le deuxième étrier 22 permet par exemple de fixer la traverse 12 à un deuxième montant A de la caisse BIW du véhicule automobile V. Le deuxième étrier 22 est par exemple en matériau contenant du plastique ou en métal. Le deuxième étrier 22 est par exemple emmanché en force et/ou vissé et/ou soudé sur la deuxième portion 16 de la traverse 12. The dashboard crossmember assembly 10 comprises a second bracket 22 for fixing the crossmember 12 to the BIW body of the motor vehicle V. The second bracket 22 makes it possible, for example, to fix the crossmember 12 to a second pillar A of the BIW body of the motor vehicle V. The second stirrup 22 is for example made of material containing plastic or metal. The second stirrup 22 is for example press-fitted and/or screwed and/or welded onto the second portion 16 of the crosspiece 12.
[0036] Dans la suite, on décrit plus en détail la deuxième portion 16 de la traverse 12, notamment en regard des figures 3 à 6. [0036] In the following, the second portion 16 of the crosspiece 12 is described in more detail, in particular with reference to Figures 3 to 6.
[0037] Comme visible sur les figures 3 et 4, la deuxième portion 16 de la traverse 12 comprend essentiellement une partie centrale 16i de forme extérieure cylindrique, s’étendant selon la direction de l’axe A d’extension de la traverse 12, entre un premier relief d’extrémité 162 et un deuxième relief d’extrémité 163. Par « cylindrique », on entend ici une forme présentant une section transversale dont le contour est constant, s’étendant selon un axe longitudinal, correspondant ici à l’axe A d’extension de la traverse 12. De préférence, la partie centrale 161 de la deuxième portion 16 de la traverse 12 a une section transversale sensiblement en forme de « S ». As visible in Figures 3 and 4, the second portion 16 of the crosspiece 12 essentially comprises a central part 16i of cylindrical external shape, extending in the direction of the axis A of extension of the crosspiece 12, between a first end relief 162 and a second end relief 163. By “cylindrical” is meant here a shape having a cross section whose contour is constant, extending along a longitudinal axis, corresponding here to the axis A of extension of the crosspiece 12. Preferably, the central part 161 of the second portion 16 of the crosspiece 12 has a cross section substantially in the shape of an “S”.
[0038] La partie centrale 161 de la deuxième portion 16 de la traverse 12 forme une pluralité de premières interfaces de fixation 24, ici sous la forme de premiers logements 25. Ici, tous les premiers logements 25 sont identiques. Selon l’exemple représenté, vingt-quatre premiers logements 25 sont réalisés sur l’intégralité de la longueur de la partie centrale 161 de la deuxième portion 16 de la traverse 12. Bien entendu, ce nombre n’est nullement limitatif et un nombre différent de premiers logements 25 peut être réalisé sur la partie centrale 161. Notamment, un nombre de premiers logements 25 supérieur ou égal à 4, de préférence supérieur ou égal à 8, et/ou inférieur ou égal à 40, de préférence inférieur ou égal à 30, peut être formé sur la partie centrale 161 de la deuxième portion 16 de la traverse 12. En outre, ici, les premiers logements 25 sont réalisés sur sensiblement toute la longueur de la partie centrale 161 de la deuxième portion 16 de la traverse 12. Alternativement, des premiers logements 25 peuvent n’être réalisés que sur une longueur limitée de la partie centrale 16i de la deuxième portion 16 de la traverse 12. De préférence, des premiers logements 25 sont réalisés sur au moins 25 %, de préférence sur au moins 50 %, de préférence encore sur au moins 75 % et de manière encore plus préférée sur 100 % de la longueur de la partie centrale 161 de la deuxième portion 16 de la traverse 12. The central part 161 of the second portion 16 of the crosspiece 12 forms a plurality of first fixing interfaces 24, here in the form of first housings 25. Here, all the first housings 25 are identical. According to the example shown, twenty-four first housings 25 are made over the entire length of the central part 161 of the second portion 16 of the crosspiece 12. Of course, this number is in no way limiting and a different number of first housings 25 can be made on the central part 161. In particular, a number of first housings 25 greater than or equal to 4, preferably greater than or equal to 8, and/or less than or equal to 40, preferably less than or equal to 30, can be formed on the central part 161. 161 of the second portion 16 of the crosspiece 12. In addition, here, the first housings 25 are made over substantially the entire length of the central part 161 of the second portion 16 of the crosspiece 12. Alternatively, the first housings 25 can n be made only over a limited length of the central part 16i of the second portion 16 of the crosspiece 12. Preferably, first housings 25 are made over at least 25%, preferably over at least 50%, more preferably over at least 75% and even more preferably over 100% of the length of the central part 161 of the second portion 16 of the crosspiece 12.
[0039] Lorsque la partie centrale 161 de la deuxième portion 16 de la traverse 12 a une section transversale sensiblement en forme de « S », la forme en « S » peut être définie par une branche centrale, s’étendant entre deux branches d’extrémité, de préférence sensiblement parallèles à la branche centrale, chaque branche d’extrémité étant reliée à la branche centrale par une branche de liaison, de préférence sensiblement verticale. Avec une telle section transversale en « S » de la partie centrale 161 de la deuxième portion 16 de la traverse 12, les logements 25 peuvent être délimités par la branche centrale et l’une des deux branches d’extrémité - aussi dite extérieure ou extrémale, notamment supérieure - du « S », d’une part, et par deux nervures ou parois de renfort voisines, d’autre part, les nervures ou parois de renfort s’étendant entre les faces de la parties centrale 161 de la deuxième portion 16 de la traverse 12 formant la branche centrale et la deuxième branche. Par exemple, les nervures ou parois de renfort s’étendent sensiblement verticalement. When the central part 161 of the second portion 16 of the crosspiece 12 has a cross section substantially in the shape of an “S”, the “S” shape can be defined by a central branch, extending between two branches of end, preferably substantially parallel to the central branch, each end branch being connected to the central branch by a connecting branch, preferably substantially vertical. With such an "S"-shaped cross section of the central part 161 of the second portion 16 of the crosspiece 12, the housings 25 can be delimited by the central branch and one of the two end branches - also called outer or extremal , in particular upper - of the "S", on the one hand, and by two neighboring ribs or reinforcing walls, on the other hand, the ribs or reinforcing walls extending between the faces of the central part 161 of the second portion 16 of the crosspiece 12 forming the central branch and the second branch. For example, the ribs or reinforcing walls extend substantially vertically.
[0040] Ici, chaque premier logement 25 a une forme sensiblement prismatique, à section transversale carrée, s’étendant selon un axe longitudinal compris dans un plan normal à la direction A d’extension de la traverse 12. Bien entendu, d’autres formes des premiers logements peuvent être imaginées, qui sont accessibles à l’Homme de l’art. [0040] Here, each first housing 25 has a substantially prismatic shape, with a square cross section, extending along a longitudinal axis included in a plane normal to the direction A of extension of the crosspiece 12. Of course, other forms of the first housing can be imagined, which are accessible to those skilled in the art.
[0041] Chaque premier logement 25 permet ainsi de recevoir, serré, un ergot 26 d’une patte de fixation 28. Chaque ergot 26 est de forme complémentaire à un premier logement 25 associé. Cependant, pour faciliter l’insertion de l’ergot 26 dans un premier logement 25, l’ergot 26 peut être muni de lames 30 qui entrent en contact avec les parois d’un premier logement 25 quand l’ergot 26 est inséré dans le premier logement 25. Ainsi, le frottement entre l’ergot 26 et les parois du premier logement 25 associé intervient sur une surface moindre, facilitant l’insertion de l’ergot 26 dans le premier logement 25 associé. Chaque lame 30 peut s’étendre par exemple sensiblement perpendiculairement à la surface dont elle est issue. De préférence, les ergots 26 sont creux pour faciliter leurs réalisations, notamment par moulage. Alternativement, l’ergot 26 est reçu dans le premier logement 25 avec jeu. Dans ce cas, l’ergot 26 peut être fixé dans le premier logement 25 au moyen d’un élément de fixation, comme par exemple une vis et/ou un rivet. [0041] Each first housing 25 thus makes it possible to receive, tight, a lug 26 of a fixing lug 28. Each lug 26 is of complementary shape to a first associated housing 25. However, to facilitate the insertion of the lug 26 in a first housing 25, the lug 26 can be provided with blades 30 which come into contact with the walls of a first housing 25 when the lug 26 is inserted into the first housing 25. Thus, the friction between the lug 26 and the walls of the first associated housing 25 occurs on a smaller surface, facilitating the insertion of the lug 26 in the first associated housing 25. Each blade 30 can extend for example substantially perpendicular to the surface from which it comes. Preferably, the lugs 26 are hollow to facilitate their production, in particular by molding. Alternatively, the lug 26 is received in the first housing 25 with play. In this case, the lug 26 can be fixed in the first housing 25 by means of a fixing element, such as for example a screw and/or a rivet.
[0042] Dans un mode de réalisation non représenté, un dispositif de fixation par emboîtage élastique (ou clip de fixation), par exemple métallique, est intégré dans le premier logement 25, de préférence au fond du premier logement 25. L’ergot 26 peut alors comporter une forme complémentaire, par exemple un relief complémentaire, pour coopérer avec ce dispositif de fixation par emboîtage élastique. [0042] In an embodiment not shown, a fixing device by elastic fitting (or fixing clip), for example metallic, is integrated into the first housing 25, preferably at the bottom of the first housing 25. The lug 26 can then include a complementary shape, for example a complementary relief, to cooperate with this fixing device by elastic interlocking.
[0043] Comme cela est notamment visible sur la figure 5, chaque patte de fixation 28 peut comporter en outre une première surface 31 , ici supérieure, et/ou une deuxième surface 33, ici inférieure, définissant un logement recevant la deuxième portion 16 longitudinale de traverse 12, serrée. Ainsi, la deuxième portion 16 longitudinale de traverse 12 peut être serrée entre au moins l’un parmi : [0043] As is particularly visible in Figure 5, each fixing lug 28 may further comprise a first surface 31, here upper, and/or a second surface 33, here lower, defining a housing receiving the second longitudinal portion 16 of crosspiece 12, tight. Thus, the second longitudinal portion 16 of crosspiece 12 can be clamped between at least one of:
- les deux surfaces 31 , 33, - the two surfaces 31, 33,
- entre la première surface 31 et un ergot 26 de la patte de fixation 28, et/ou - between the first surface 31 and a lug 26 of the fixing bracket 28, and/or
- entre la deuxième surface 33 et un ergot 26 de la patte de fixation 28. - between the second surface 33 and a lug 26 of the fixing lug 28.
[0044] Ici, en outre, la partie centrale 161 de la deuxième portion 16 de la traverse 12 forme une pluralité de deuxièmes interfaces de fixation 36. Chaque deuxième interface de fixation 36 est ici réalisée sous la forme d’un deuxième logement 37. Ici, tous les deuxièmes logements 37 sont identiques. Selon l’exemple représenté, vingt-quatre deuxièmes logements 37 sont réalisés sur l’intégralité de la longueur de la partie centrale 161 de la deuxième portion 16 de la traverse 12. Bien entendu, ce nombre n’est nullement limitatif et un nombre différent de deuxièmes logements 37 peut être réalisé sur la partie centrale 161. Notamment, un nombre de deuxièmes logements 37 supérieur ou égal à 4, de préférence supérieur ou égal à 8, et/ou inférieur ou égal à 40, de préférence inférieur ou égal à 30, peut être formé sur la partie centrale 161 de la deuxième portion 16 de la traverse 12. En outre, ici, les deuxièmes logements 37 sont réalisés sur sensiblement toute la longueur de la partie centrale 16i de la deuxième portion 16 de la traverse 12. Alternativement, des deuxièmes logements 37 peuvent n’être réalisés que sur une longueur limitée de la partie centrale 161 de la deuxième portion 16 de la traverse 12. De préférence, des deuxièmes logements 37 sont réalisés sur au moins 25 %, de préférence sur au moins 50 %, de préférence encore sur au moins 75 % et de manière encore plus préférée sur 100 % de la longueur de la partie centrale 161 de la deuxième portion 16 de la traverse 12. [0045] Lorsque la partie centrale 161 de la deuxième portion 16 de la traverse 12 a une section transversale sensiblement en forme de « S », comme décrite précédemment, les logements 37 peuvent être délimités par la branche centrale et l’une des deux branches d’extrémité - aussi dite extérieure ou extrémale, notamment inférieure - du « S », d’une part, et par deux nervures ou parois de renfort voisines, d’autre part, les nervures ou parois de renfort s’étendant entre les faces de la parties centrale 161 de la deuxième portion 16 de la traverse 12 formant la branche centrale et la deuxième branche. Par exemple, les nervures ou parois de renfort s’étendent sensiblement verticalement. [0044] Here, in addition, the central part 161 of the second portion 16 of the crosspiece 12 forms a plurality of second fixing interfaces 36. Each second fixing interface 36 is here produced in the form of a second housing 37. Here, all the second housings 37 are identical. According to the example shown, twenty-four second housings 37 are made over the entire length of the central part 161 of the second portion 16 of the crosspiece 12. Of course, this number is in no way limiting and a different number second housings 37 can be produced on the central part 161. In particular, a number of second housings 37 greater than or equal to 4, preferably greater than or equal to 8, and/or less than or equal to 40, preferably less than or equal to 30, can be formed on the central part 161 of the second portion 16 of the crosspiece 12. In addition, here, the second housings 37 are made over substantially the entire length of the central part 16i of the second portion 16 of the crosspiece 12 Alternatively, second housings 37 can only be made over a limited length of the central part 161 of the second portion 16 of the crosspiece 12. Preferably, second housings 37 are made over at least 25%, preferably over at least 50%, more preferably at least 75% and even more preferably 100% of the length of the central part 161 of the second portion 16 of the crosspiece 12. When the central part 161 of the second portion 16 of the crosspiece 12 has a cross section substantially in the shape of an "S", as described previously, the housings 37 can be delimited by the central branch and one of the two branches end - also called external or extremal, in particular lower - of the "S", on the one hand, and by two neighboring ribs or reinforcing walls, on the other hand, the ribs or reinforcing walls extending between the faces of the central part 161 of the second portion 16 of the crosspiece 12 forming the central branch and the second branch. For example, the reinforcing ribs or walls extend substantially vertically.
[0046] Ici, chaque deuxième logement 37 a une forme sensiblement prismatique, à section transversale carrée, s’étendant selon un axe longitudinal compris dans un plan normal à la direction A d’extension de la traverse 12. Bien entendu, d’autres formes des deuxièmes logements 37 peuvent être imaginées, qui sont accessibles à l’Homme de l’art. [0046] Here, each second housing 37 has a substantially prismatic shape, with a square cross section, extending along a longitudinal axis included in a plane normal to the direction A of extension of the crosspiece 12. Of course, other shapes of the second housings 37 can be imagined, which are accessible to those skilled in the art.
[0047] Les deuxièmes logements 37 sont ici réalisés de manière à déboucher sur une face de la partie centrale 161 de la deuxième portion 16 de la traverse 12, opposée à la face de la partie centrale 161 de la deuxième portion 16 de la traverse 12, sur laquelle les premiers logements 25 débouchent. The second housings 37 are here made so as to open onto one face of the central part 161 of the second portion 16 of the crosspiece 12, opposite the face of the central part 161 of the second portion 16 of the crosspiece 12 , onto which the first housing units 25 lead.
[0048] Ici, comme cela est illustré aux figures 5 et 6, dans un plan transversal à l’axe A d’extension de la traverse 12, la section de chaque deuxième logement 37 est sensiblement symétrique à la section d’un premier logement 25, par rapport à l’axe A d’extension de la traverse 12. [0048] Here, as illustrated in Figures 5 and 6, in a plane transverse to the axis A of extension of the crosspiece 12, the section of each second housing 37 is substantially symmetrical to the section of a first housing 25, relative to the axis A of extension of the crosspiece 12.
[0049] Chaque deuxième logement 37 permet de recevoir, serré, un ergot 26 d’une patte de fixation 28. Pour faciliter l’insertion de l’ergot 26 dans un deuxième logement 37, l’ergot 26 peut être muni de lames 30 qui entrent en contact avec les parois d’un deuxième logement 37 quand l’ergot 26 est inséré dans le deuxième logement 25 associé. Ainsi, le frottement entre l’ergot 26 et les parois du deuxième logement 37 associé s’effectue sur une surface moindre, facilitant l’insertion de l’ergot 26 dans le premier logement 37 associé. Dans ce cas, chaque lame 30 peut s’étendre perpendiculairement à la surface dont elle est issue. [0049] Each second housing 37 makes it possible to receive, tight, a lug 26 of a fixing lug 28. To facilitate the insertion of the lug 26 in a second housing 37, the lug 26 can be provided with blades 30 which come into contact with the walls of a second housing 37 when the lug 26 is inserted into the second associated housing 25. Thus, the friction between the lug 26 and the walls of the second associated housing 37 takes place over a smaller surface area, facilitating the insertion of the lug 26 into the first associated housing 37. In this case, each blade 30 can extend perpendicular to the surface from which it comes.
[0050] Alternativement, l’ergot 26 peut être reçu dans le deuxième logement 37 avec un jeu. Dans ce cas, l’ergot 26 peut être fixé dans le deuxième logement 37 au moyen d’un élément de fixation, comme par exemple une vis et/ou un rivet. Alternatively, the lug 26 can be received in the second housing 37 with a clearance. In this case, the lug 26 can be fixed in the second housing 37 by means of a fixing element, such as for example a screw and/or rivet.
[0051] Dans un mode de réalisation non représenté, un dispositif de fixation par emboîtage élastique (ou clip de fixation), par exemple métallique, est intégré dans un deuxième logement 37, de préférence au fond du deuxième logement 37. L’ergot 26 peut alors comporter une forme complémentaire, par exemple un relief complémentaire, pour coopérer avec ce dispositif de fixation par emboîtage élastique. [0051] In an embodiment not shown, a fixing device by elastic fitting (or fixing clip), for example metallic, is integrated in a second housing 37, preferably at the bottom of the second housing 37. The lug 26 can then include a complementary shape, for example a complementary relief, to cooperate with this fixing device by elastic interlocking.
[0052] Comme cela est notamment visible sur la figure 6, chaque patte de fixation 28 peut comporter en outre une première surface 31 , ici supérieure, et/ou une deuxième surface 33, ici inférieure, définissant un logement recevant la deuxième portion 16 longitudinale de traverse 12, serrée. Ainsi, la deuxième portion 16 longitudinale de traverse 12 peut être serrée entre au moins l’un parmi : [0052] As is particularly visible in Figure 6, each fixing lug 28 may further comprise a first surface 31, here upper, and/or a second surface 33, here lower, defining a housing receiving the second longitudinal portion 16 of crosspiece 12, tight. Thus, the second longitudinal portion 16 of crosspiece 12 can be clamped between at least one of:
- les deux surfaces 31 , 33, - the two surfaces 31, 33,
- entre la première surface 31 et un ergot 26 de la patte de fixation 28, et/ou - between the first surface 31 and a lug 26 of the fixing bracket 28, and/or
- entre la deuxième surface 33 et un ergot 26 de la patte de fixation 28. - between the second surface 33 and a lug 26 of the fixing lug 28.
[0053] Chaque patte de fixation 28 appartient à un support 34 de fixation d’un accessoire sur la traverse 12. Comme notamment illustré à la figure 10, chaque accessoire pouvant être ainsi fixé sur la traverse 12, notamment sur la deuxième portion 16 de la traverse 12, peut par exemple être choisi parmi : [0053] Each fixing tab 28 belongs to a support 34 for fixing an accessory on the crosspiece 12. As illustrated in particular in Figure 10, each accessory can thus be fixed on the crosspiece 12, in particular on the second portion 16 of the crosspiece 12, can for example be chosen from:
- une boîte à gants G ; - a glove box G;
- un module de coussin gonflable de sécurité Ab ; - an Ab safety airbag module;
- un module électronique M ; - an electronic module M;
- un écran S, notamment un écran central ; - an S screen, in particular a central screen;
- une planche de bord D ; - a dashboard D;
- un habillage intérieur Tr, notamment côté conducteur et/ou côté passager ; - interior trim Tr, in particular on the driver's side and/or passenger's side;
- un dispositif de vision tête haute H ; - a head-up vision device H;
- un tableau de bord Tb comprenant au moins un compteur ou dispositif d’affichage Di équivalent d’une information relative au véhicule automobile V, notamment un compteur de vitesse et/ou de régime moteur du véhicule automobile V, et/ou au moins un tel compteur ou dispositif d’affichage Di. - a dashboard Tb comprising at least one counter or display device Di equivalent of information relating to the motor vehicle V, in particular a speed and/or engine speed counter of the motor vehicle V, and/or at least one such meter or display device Di.
[0054] Comme visible sur la figure 1 , chaque support 34 de fixation d’un accessoire sur la traverse 12 peut comporter une patte de fixation 28, deux pattes de fixation 28 voire plus de deux pattes de fixation 28. Le nombre de pattes de fixation 28 d’un support 34 peut notamment être choisi en fonction du poids de l’accessoire à supporter. [0054] As visible in Figure 1, each support 34 for fixing an accessory on the crosspiece 12 can comprise a fixing lug 28, two fixing lugs 28 or even more than two fixing lugs 28. The number of fixing lugs fixing 28 of a support 34 can in particular be chosen according to the weight of the accessory to be supported.
[0055] Alternativement ou au surplus, au moins une patte de fixation 28 peut être fixée à la caisse BIW du véhicule automobile V et renforcer ainsi la fixation de l’ensemble de traverse de planche de bord 10 sur la caisse BIW du véhicule automobile V. Une telle patte de fixation 28 peut par exemple être fixée au tablier Ta de la caisse BIW du véhicule automobile ou à une traverse inférieure de baie T de la caisse BIW du véhicule automobile V. [0056] On rappelle ici que la caisse BIW d'un véhicule automobile V comporte, d'avant en arrière, un compartiment moteur qui est fermé par un capot et qui est séparé de l'habitacle du véhicule par un tablier Ta et, en partie supérieure, par une traverse inférieure de baie T. La traverse inférieure de baie T peut être monobloc avec le tablier Ta. La traverse inférieure de baie Ta se distingue alors du tablier T du fait qu’elle s’étend sensiblement horizontalement alors que le tablier Ta s’étend plutôt verticalement ou en biais dans la direction verticale. La traverse inférieure de baie T est destinée à supporter une partie inférieure d'un pare-brise du véhicule automobile V. [0055] Alternatively or additionally, at least one fixing bracket 28 can be fixed to the BIW body of the motor vehicle V and thus reinforce the fixing of the dashboard crossmember assembly 10 on the BIW body of the motor vehicle V Such a fixing bracket 28 can for example be fixed to the apron Ta of the BIW body of the motor vehicle or to a lower bay cross member T of the BIW body of the motor vehicle V. [0056] We recall here that the body BIW of a motor vehicle V comprises, from front to rear, an engine compartment which is closed by a hood and which is separated from the passenger compartment of the vehicle by an apron Ta and, in upper part, by a lower bay crossbar T. The lower bay crossbar T can be in one piece with the apron Ta. The lower bay crosspiece Ta is then distinguished from the apron T in that it extends substantially horizontally whereas the apron Ta extends rather vertically or at an angle in the vertical direction. The lower bay cross member T is intended to support a lower part of a windshield of the motor vehicle V.
[0057] Par ailleurs, le deuxième relief d’extrémité 163 est adapté pour permettre une fixation du premier étrier 20, par exemple par complémentarité de formes. Par exemple, le premier étrier 20 forme un logement de réception serrée d’une partie au moins du deuxième relief d’extrémité 163 et/ou le deuxième relief d’extrémité 163 forme un logement de réception d’un relief complémentaire du premier étrier 20. De préférence, le premier étrier 20 forme un logement de réception serrée d’une partie au moins du deuxième relief d’extrémité 163 et le deuxième relief d’extrémité 163 forme un logement de réception d’un relief complémentaire du premier étrier 20, les reliefs et logements étant coaxiaux, par exemple d’axe l’axe A d’extension de la traverse 12. Alternativement ou au surplus, le deuxième relief d’extrémité 163 et le premier étrier 20 comprennent chacun un relief, par exemple un trou, pour permettre de visser ensemble la deuxième portion 16 de la traverse 12 et le premier embout 20, notamment lorsque le logement du premier étrier 20 reçoit une partie au moins du deuxième relief d’extrémité 163 et/ou que le logement dans le deuxième relief d’extrémité 163 reçoit le relief complémentaire du premier étrier 20. [0057] Furthermore, the second end relief 163 is adapted to allow fixing of the first stirrup 20, for example by complementarity of shapes. For example, the first stirrup 20 forms a housing for tightly receiving at least part of the second end relief 163 and/or the second end relief 163 forms a housing for receiving a complementary relief of the first stirrup 20 Preferably, the first stirrup 20 forms a housing for tightly receiving at least part of the second end relief 163 and the second end relief 163 forms a housing for receiving a complementary relief of the first stirrup 20, the reliefs and housings being coaxial, for example of axis the axis A of extension of the crosspiece 12. Alternatively or additionally, the second end relief 163 and the first stirrup 20 each comprise a relief, for example a hole , to allow the second portion 16 of the crosspiece 12 and the first end piece 20 to be screwed together, in particular when the housing of the first stirrup 20 receives at least part of the second end relief 163 and/or the housing in the second relief end 163 receives the complementary relief of the first stirrup 20.
[0058] Le premier relief d’extrémité 162 comporte au moins l’un parmi un relief adapté à être reçu serré dans la première portion longitudinale 14 et un relief adapté à recevoir une extrémité de la première portion longitudinale 14, serrée. De préférence, le premier relief d’extrémité 162 comporte à la fois un relief adapté à être reçu serré dans la première portion longitudinale 14 et un relief adapté à recevoir une extrémité de la première portion longitudinale 14, serrée. Tel qu’illustré, le premier relief d’extrémité 162 est saillant longitudinalement depuis une base 42, sensiblement plane, perpendiculaire à l’axe A d’extension de la traverse 12. La base 42 est saillante radialement par rapport à la partie centrale 163 de la deuxième portion 16 de la traverse 12. Ici, la base 42 a une forme générale de disque, de centre compris sur l’axe A d’extensions de la traverse 12. The first end relief 162 comprises at least one of a relief adapted to be received tightly in the first longitudinal portion 14 and a relief adapted to receive one end of the first longitudinal portion 14, clamped. Preferably, the first end relief 162 comprises both a relief adapted to be received tightly in the first longitudinal portion 14 and a relief adapted to receive one end of the first longitudinal portion 14, clamped. As illustrated, the first end relief 162 projects longitudinally from a base 42, substantially flat, perpendicular to the axis A of extension of the crosspiece 12. The base 42 projects radially relative to the central part 163 of the second portion 16 of the crosspiece 12. Here, the base 42 has a general disc shape, with a center included on the axis A of extensions of the crosspiece 12.
[0059] La traverse 12 obtenue par l’emmanchement, ici en force, des première et deuxième portions longitudinales 14, 16 ensemble, est reçue dans un raccord de fixation 56, tel qu’illustré à la figure 7. Par « emmanchement », on entend ici un recouvrement partiel des deux portions longitudinales 14, 16, notamment la réception d’une partie au moins d’une portion longitudinale dans l’autre partie longitudinale. On entend par « emmanchement en force », un recouvrement partiel avec frottement, notamment une réception d’une partie au moins d’une portion longitudinale dans l’autre partie longitudinale, avec frottement. The crosspiece 12 obtained by the fitting, here by force, of the first and second longitudinal portions 14, 16 together, is received in a fixing connector 56, as illustrated in Figure 7. By "fitting", here we mean a partial covering of the two longitudinal portions 14, 16, in particular the reception of at least part of one longitudinal portion in the other longitudinal part. By “forced fitting” is meant a partial covering with friction, in particular a reception of at least part of a longitudinal portion in the other longitudinal part, with friction.
[0060] Comme cela est notamment visible sur la figure 1 ou la figure 2, le raccord de fixation 56 s’étend à l’extérieur des première et deuxième portions longitudinales 14, 16. De préférence, le raccord de fixation 56 est cependant en contact avec chacune des première et deuxième portions longitudinales 14, 16, par exemple sur une partie des première et deuxième portions longitudinales 14, 16 correspondant à un secteur angulaire d’un tronçon longitudinal des première et deuxième portions longitudinales 14, 16. Le contact entre le raccord de fixation 56 et chacune des première et deuxième portions longitudinales 14, 16, à l’extérieur de ces portions longitudinales 14, 16 contribue à renforcer la fixation des première et deuxième portions longitudinales 14, 16 ensemble, notamment en limitant voire en évitant au moins certains mouvements relatifs des portions longitudinales 14, 16, l’une par rapport à l’autre, et/ou un mouvement de l’ensemble formé des première et deuxième portions longitudinales 14, 16 par rapport à la caisse du véhicule BIW. [0060] As is particularly visible in Figure 1 or Figure 2, the fixing connector 56 extends outside the first and second longitudinal portions 14, 16. Preferably, the fixing connector 56 is however in contact with each of the first and second longitudinal portions 14, 16, for example on a part of the first and second longitudinal portions 14, 16 corresponding to an angular sector of a longitudinal section of the first and second longitudinal portions 14, 16. The contact between the fixing connector 56 and each of the first and second longitudinal portions 14, 16, outside of these longitudinal portions 14, 16 contributes to reinforcing the fixing of the first and second longitudinal portions 14, 16 together, in particular by limiting or even avoiding at least certain relative movements of the longitudinal portions 14, 16, relative to each other, and/or a movement of the assembly formed of the first and second longitudinal portions 14, 16 relative to the body of the BIW vehicle.
[0061] Comme illustré sur cette figure 7, le raccord de fixation 56 comporte tout d’abord un premier logement 58 de réception d’une portion d’extrémité de la première portion 14 de la traverse 12. Ici le premier logement 58 est formé par une surface 60 bombée de manière complémentaire à la surface extérieure de la portion d’extrémité de la première portion 14 de la traverse 12. Ainsi, la surface 60 a ici la forme d’un secteur angulaire de cylindre, de rayon sensiblement égal au rayon extérieur de la première portion 14 de la traverse 12 et d’axe correspondant à l’axe A d’extension de la traverse 12 dans l’ensemble de traverse de planche de bord 10. [0061] As illustrated in this Figure 7, the fixing connector 56 firstly comprises a first housing 58 for receiving an end portion of the first portion 14 of the crosspiece 12. Here the first housing 58 is formed by a surface 60 curved in a manner complementary to the exterior surface of the end portion of the first portion 14 of the crosspiece 12. Thus, the surface 60 here has the shape of an angular sector of a cylinder, of radius substantially equal to the outer radius of the first portion 14 of the cross member 12 and axis corresponding to the axis A of extension of the cross member 12 in the dashboard cross member assembly 10.
[0062] La surface 60 présente ici un trou traversant 62 destiné à être disposé en vis-à-vis d’un trou traversant la paroi de la portion d’extrémité de la première portion 14 de la traverse 12 dans l’ensemble de traverse de planche de bord 10. Il est ainsi possible de fixer ensemble le raccord de fixation 56 et la première portion 14 de la traverse 12, reçue dans le premier logement 58, en un premier point de fixation, par exemple au moyen d’un dispositif de fixation démontable. Une fixation démontable permet de démonter la traverse en fin de vie, pour récupérer ses éléments constitutifs et les recycler. Un dispositif de fixation démontable est par exemple une vis ou un boulon. Par opposition, une soudure, par exemple, n’apparait pas comme un dispositif de fixation démontable. Ici, le trou traversant 62 est destiné à être en regard d’une ouverture dans le premier relief d’extrémité 162 de la deuxième portion 16 de la traverse 12 et d’une ouverture dans la première portion longitudinale 14 de la traverse 12. Ainsi, en ce premier point de fixation, on fixe ensemble, à l’aide d’un seul dispositif de fixation démontable, le raccord de fixation 56, la première portion 14 de la traverse 12 et la deuxième portion 16 de la traverse 12. [0062] The surface 60 here has a through hole 62 intended to be arranged opposite a hole passing through the wall of the end portion of the first portion 14 of the crosspiece 12 in the crosspiece assembly dashboard 10. It is thus possible to fix together the fixing connector 56 and the first portion 14 of the crosspiece 12, received in the first housing 58, at a first fixing point, for example by means of a device removable fixing. A removable fixing allows the crosspiece to be dismantled at the end of its life, to recover its constituent elements and recycle them. A removable fixing device is for example a screw or a bolt. In contrast, a weld, for example, does not appear as a removable fixing device. Here, the through hole 62 is intended to face an opening in the first end relief 162 of the second portion 16 of the crosspiece 12 and an opening in the first longitudinal portion 14 of the crosspiece 12. Thus , at this first fixing point, we fix together, using a single removable fixing device, the fixing connector 56, the first portion 14 of the crosspiece 12 and the second portion 16 of the crosspiece 12.
[0063] Le raccord de fixation 56 comporte également un deuxième logement 64 adapté à recevoir une partie d’extrémité de la deuxième portion 16 de la traverse 12, disposée au voisinage du premier relief d’extrémité 162. Le deuxième logement 64 est ainsi délimité par une surface 66 cylindrique, d’axe l’axe A d’extension de la traverse 12, dans l’ensemble de traverse de planche de bord 10. La section transversale de la surface 66 est sensiblement complémentaire au contour externe de la section transversale de la deuxième portion 16 de la traverse 12, en particulier au voisinage du premier relief d’extrémité 162. [0063] The fixing connector 56 also comprises a second housing 64 adapted to receive an end part of the second portion 16 of the crosspiece 12, arranged in the vicinity of the first end relief 162. The second housing 64 is thus delimited by a cylindrical surface 66, of axis the axis A of extension of the cross member 12, in the dashboard cross member assembly 10. The cross section of the surface 66 is substantially complementary to the external contour of the cross section of the second portion 16 of the crosspiece 12, in particular in the vicinity of the first end relief 162.
[0064] En outre, ici, deux ergots 38 tels que décrits précédemment, s’étendent depuis la surface 66 délimitant le deuxième logement 64 du raccord de fixation 56. Les deux ergots 38 sont ici adaptés à être reçus serrés, dans des deuxièmes logements 37 de la deuxième portion 16 de la traverse 12. Comme illustré, les ergots 38 peuvent comprendre des lames 30 s’étendant perpendiculairement à la surface dont les lames 30 sont issues. Les ergots 38 permettent ainsi de fixer le raccord de fixation 56 à la deuxième portion 16 de la traverse 12. [0064] Furthermore, here, two lugs 38 as described above extend from the surface 66 delimiting the second housing 64 of the fixing connector 56. The two lugs 38 are here adapted to be received tight, in second housings 37 of the second portion 16 of the crosspiece 12. As illustrated, the lugs 38 may comprise blades 30 extending perpendicular to the surface from which the blades 30 come. The lugs 38 thus make it possible to fix the fixing connector 56 to the second portion 16 of the crosspiece 12.
[0065] Ici, en outre, un trou traversant 68 est prévu à travers la surface 66 délimitant le deuxième logement 64, destiné à être en vis-à-vis d’une ouverture 70 à travers une paroi délimitant un premier logement 25 dans la deuxième portion 16 de la traverse 12. Il est ainsi possible de fixer ensemble le raccord de fixation 56 et la deuxième portion 16 de la traverse 12 en un deuxième point de fixation, par exemple au moyen d’un dispositif de fixation démontable. Là encore, par dispositif de fixation démontable, on comprend par exemple une vis ou un boulon. [0065] Here, in addition, a through hole 68 is provided through the surface 66 delimiting the second housing 64, intended to be opposite an opening 70 through a wall delimiting a first housing 25 in the second portion 16 of the crosspiece 12. It is thus possible to fix together the fixing connector 56 and the second portion 16 of the crosspiece 12 at a second fixing point, for example by means of a removable fixing device. Here again, by removable fixing device, we understand for example a screw or a bolt.
[0066] Le raccord de fixation 56 comporte encore un troisième logement 72, disposé entre les premier et deuxième logements 58, 64 dans la direction de l’axe A d’extension de la traverse 12, dans l’ensemble de traverse de planche de bord 10. Le troisième logement 72 comporte une gorge 74 en creux, adaptée à recevoir la base 42 du premier relief d’extrémité I62 de la deuxième portion 16 de la traverse 12. Ici, la gorge 74 du troisième logement 72 est conformée pour limiter voire empêcher un mouvement de la base 42 reçue dans la gorge 74, selon la direction de l’axe A d’extension de la traverse 12, dans l’ensemble de traverse de planche de bord 10. Ici, la gorge 74 est délimitée par une paroi en forme de portion de cylindre, d’axe l’axe A d’extension de la traverse 12. [0066] The fixing connector 56 also comprises a third housing 72, disposed between the first and second housings 58, 64 in the direction of the axis A of extension of the crosspiece 12, in the board crosspiece assembly. edge 10. The third housing 72 comprises a recessed groove 74, adapted to receive the base 42 of the first end relief I62 of the second portion 16 of the crosspiece 12. Here, the groove 74 of the third housing 72 is shaped to limit or even prevent movement of the base 42 received in the groove 74, in the direction of the axis A of extension of the cross member 12, in the dashboard cross member assembly 10. Here, the groove 74 is delimited by a wall in the form of a portion of a cylinder, with axis A of extension of the crosspiece 12.
[0067] Selon une variante, un élément de fixation fixe le raccord de fixation 56, au niveau du troisième logement 72, à la fois avec une partie de la première portion longitudinale 14 de la traverse 12 et une partie de la seconde portion longitudinale 16 de la traverse 12. De préférence, l’élément de fixation est en contact avec la première portion longitudinale 14 et la deuxième portion longitudinale 16 au niveau de la zone d’emmanchement l’une dans l’autre des première et deuxième portions longitudinales 14, 16. L’élément de fixation est par exemple une vis et/ou un rivet. Le raccord de fixation 56 contribue ainsi à une fixation particulièrement robuste des deux portions 14, 16 longitudinales de la traverse 12, ensemble. According to a variant, a fixing element fixes the fixing connection 56, at the level of the third housing 72, both with a part of the first longitudinal portion 14 of the crosspiece 12 and a part of the second longitudinal portion 16 of the crosspiece 12. preferably, the fixing element is in contact with the first longitudinal portion 14 and the second longitudinal portion 16 at the level of the fitting zone one into the other of the first and second longitudinal portions 14, 16. The element fixing is for example a screw and/or a rivet. The fixing connector 56 thus contributes to a particularly robust fixing of the two longitudinal portions 14, 16 of the crosspiece 12, together.
[0068] En outre, dans l’exemple illustré, le raccord de fixation 56 forme une jambe de force 32. La jambe de force 32 peut par exemple être destinée à être fixée à la caisse BIW du véhicule automobile V, notamment au tunnel Tu formé par le plancher de la caisse BIW pour recevoir un arbre de transmission et/ou un conduit d’échappement de gaz. Alternativement, la jambe de force 32 peut être destinée à être fixée à un boîtier de système de chauffage, de ventilation et de climatisation HVAC de l’habitacle du véhicule automobile V. Dans ce cas, la fixation des deux portions longitudinales 14, 16 de la traverse 12 est encore renforcée. [0068] Furthermore, in the example illustrated, the fixing connector 56 forms a strut 32. The strut 32 can for example be intended to be fixed to the BIW body of the motor vehicle V, in particular to the tunnel Tu formed by the floor of the BIW body to receive a transmission shaft and/or a gas exhaust duct. Alternatively, the strut 32 can be intended to be fixed to an HVAC heating, ventilation and air conditioning system housing of the passenger compartment of the motor vehicle V. In this case, the fixing of the two longitudinal portions 14, 16 of the crosspiece 12 is further reinforced.
[0069] Alternativement, le raccord de fixation 56 peut former une patte de fixation 28, destinée à permettre la fixation d’un accessoire sur la traverse 12. [0069] Alternatively, the fixing connector 56 can form a fixing lug 28, intended to allow the fixing of an accessory on the crosspiece 12.
[0070] Les figures 11 et 12 illustrent schématiquement en perspective, un détail d’un deuxième exemple d’ensemble de traverse de planche de bord 10. [0070] Figures 11 and 12 schematically illustrate in perspective, a detail of a second example of a dashboard crossmember assembly 10.
[0071] Le raccord de fixation 56 mis en œuvre dans ce deuxième exemple se distingue du raccord de fixation 56 illustré à la figure 7, essentiellement en ce qu’il est conformé pour ses ergots 38 soient reçus dans des premières interfaces de fixation 24, destinées à être orientées vers l’habitacle du véhicule équipé du deuxième exemple d’ensemble de traverse de planche de bord 10. La jambe de force 32 formé par le raccord de fixation 56 illustré sur les figures 11 et 12 est ainsi coudé, en l’espèce au voisinage de son extrémité destinée à être fixée à la caisse BIW du véhicule, notamment au tunnel Tu formé par le plancher de la caisse BIW du véhicule automobile V. [0071] The fixing connector 56 used in this second example differs from the fixing connector 56 illustrated in Figure 7, essentially in that it is shaped so that its lugs 38 are received in first fixing interfaces 24, intended to be oriented towards the passenger compartment of the vehicle equipped with the second example of a dashboard crossmember assembly 10. The strut 32 formed by the fixing connector 56 illustrated in Figures 11 and 12 is thus bent, in l species in the vicinity of its end intended to be fixed to the BIW body of the vehicle, in particular to the tunnel Tu formed by the floor of the BIW body of the motor vehicle V.
[0072] En outre, comme cela est notamment visible sur la figure 13, la tête 76 du raccord de fixation 56, formant les premier deuxième et troisième logements 58, 64 et 72, comporte une fente 78 traversante. Ici, la fente 78 est de section transversale sensiblement rectangulaire. La fente 78 traverse ici la tête 76 selon une direction sensiblement perpendiculaire à la direction de l’axe A d’extension de la traverse 12. [0072] Furthermore, as is particularly visible in Figure 13, the head 76 of the fixing connector 56, forming the first second and third housings 58, 64 and 72, has a through slot 78. Here, the slot 78 is of substantially rectangular cross section. The slot 78 here passes through the head 76 in a direction substantially perpendicular to the direction of the axis A of extension of the crosspiece 12.
[0073] La fente 78 débouche en vis-à-vis d’un renfoncement 80 dans le raccord de fixation 56. Le renfoncement 80 est ici formé dans la jambe de force 32, au voisinage de la tête 76 du raccord de fixation 56. [0074] Comme cela est visible sur les figures 11 et 12, le deuxième exemple d’ensemble de traverse de planche de bord 10 comprend en outre une pièce 82 (ci-après pièce de fixation 82) de fixation du tableau de bord Tb sur l’ensemble de traverse de planche de bord 10, notamment sur la traverse 12. La pièce de fixation 82 est notamment visible sur la figure 14. La pièce de fixation 82 comprend une tête 84 et une patte de fixation 28 du tableau de bord Tb et/ou à la traverse inférieure de baie de pare-brise. [0073] The slot 78 opens opposite a recess 80 in the fixing connector 56. The recess 80 is here formed in the strut 32, in the vicinity of the head 76 of the fixing connector 56. [0074] As can be seen in Figures 11 and 12, the second example of a dashboard crosspiece assembly 10 further comprises a part 82 (hereinafter fixing part 82) for fixing the dashboard Tb to the dashboard cross member assembly 10, in particular on the cross member 12. The fixing part 82 is particularly visible in Figure 14. The fixing part 82 comprises a head 84 and a fixing bracket 28 of the dashboard Tb and/or the lower windshield bay crossmember.
[0075] La pièce de fixation 82 est fixée sur la deuxième portion 16 de la traverse 12 sensiblement en vis-à-vis de la pièce de raccord 56. En d’autres termes, la pièce de fixation 82 et la pièce de raccord 56 sont fixées sensiblement à la même distance d’une des deux extrémités longitudinales de la traverse 12. [0075] The fixing part 82 is fixed on the second portion 16 of the crosspiece 12 substantially opposite the connecting part 56. In other words, the fixing part 82 and the connecting part 56 are fixed substantially at the same distance from one of the two longitudinal ends of the crosspiece 12.
[0076] La tête 84 de la pièce de fixation 82 comprend ici deux ergots 38 similaires aux ergots 38 de la pièce de raccord 56. Les ergots 38 de la tête 84 de la pièce de fixation 82 sont reçus chacun dans une deuxième interface de fixation 36, c'est-à-dire chacun dans un logement 37 complémentaire. [0076] The head 84 of the fixing part 82 here comprises two lugs 38 similar to the lugs 38 of the connecting part 56. The lugs 38 of the head 84 of the fixing part 82 are each received in a second fixing interface 36, that is to say each in complementary housing 37.
[0077] Par ailleurs, la patte de fixation 28 est ici à section transversale en « U ». L’extrémité frontale de la patte de fixation 28 forme, avec la tête 84, un logement 86 délimité par une surface 88 bombée de manière complémentaire à la surface extérieure de la partie centrale 161 de la deuxième portion 16 de la traverse 12. La surface 88 est percée d’un trou 90 au niveau de l’extrémité frontale de la patte de fixation 28, pour sécuriser au moyen d’un élément de fixation traversant la surface 88 et une paroi de la deuxième portion 16 de la traverse 12, la fixation de la pièce de fixation 82 à la deuxième portion 16 de la traverse 12 par réception des ergots 38 dans les logements 37 complémentaires. L’élément de fixation est de préférence démontable. L’élément de fixation est par exemple une vis, un boulon ou un rivet. D’autres moyens de fixation de la pièce de fixation 82 sur la deuxième portion 16 de la traverse 12 sont accessibles à l’Homme de l’art. [0077] Furthermore, the fixing bracket 28 here has a “U” cross section. The front end of the fixing tab 28 forms, with the head 84, a housing 86 delimited by a surface 88 curved in a manner complementary to the exterior surface of the central part 161 of the second portion 16 of the crosspiece 12. The surface 88 is pierced with a hole 90 at the front end of the fixing tab 28, to secure by means of a fixing element passing through the surface 88 and a wall of the second portion 16 of the crosspiece 12, the fixing the fixing part 82 to the second portion 16 of the crosspiece 12 by receiving the lugs 38 in the complementary housings 37. The fixing element is preferably removable. The fixing element is for example a screw, a bolt or a rivet. Other means of fixing the fixing part 82 on the second portion 16 of the crosspiece 12 are accessible to those skilled in the art.
[0078] Par ailleurs, une languette d’emboîtage élastique (ou clipsage) 92 est ici formée sur la tête 84 de la pièce de fixation 82. La languette d’emboîtage élastique 92 s’étend ici sensiblement parallèlement et dans le même sens que les ergots 38 de la pièce de fixation 82. La languette d’emboitage élastique 92 est formée d’une languette déformable élastiquement avec un cran rigide. La languette d’emboîtage élastique 92 est insérée dans la fente 78 du raccord de fixation 56 pour emboîter élastiquement le raccord de fixation 56 et la pièce de fixation 82 ensemble. La pièce de fixation 82 est ainsi directement fixée sur le raccord de fixation 56, lui-même fixé à la caisse BIW du véhicule. La fixation du tableau de bord Tb est ainsi particulièrement résistante. [0079] Alternativement ou de manière complémentaire, la pièce de fixation 82 peut être fixée sur la pièce de raccord 56 par d’autres moyens qu’un emboîtage élastique. Par exemple, la pièce de fixation 82 et la pièce de raccord 56 sont fixées ensemble au moyen d’une vis, d’un boulon ou d’un rivet. D’autres moyens de fixations, de préférence démontables, sont accessibles à l’Homme de l’art. [0078] Furthermore, an elastic interlocking tongue (or clipping) 92 is here formed on the head 84 of the fixing part 82. The elastic interlocking tongue 92 extends here substantially parallel and in the same direction as the lugs 38 of the fixing part 82. The elastic fitting tongue 92 is formed of an elastically deformable tongue with a rigid notch. The elastic nesting tab 92 is inserted into the slot 78 of the fixing connector 56 to elastically nest the fixing connector 56 and the fixing part 82 together. The fixing part 82 is thus directly fixed on the fixing connection 56, itself fixed to the BIW body of the vehicle. The Tb dashboard fixing is therefore particularly resistant. [0079] Alternatively or in a complementary manner, the fixing part 82 can be fixed on the connecting part 56 by means other than elastic fitting. For example, the fixing part 82 and the connecting part 56 are fixed together by means of a screw, a bolt or a rivet. Other means of fixing, preferably removable, are accessible to those skilled in the art.
[0080] Selon une autre alternative, la pièce de raccord 56 et la pièce de fixation 82 ne sont pas fixées directement l’une sur l’autre, la fixation de ces pièces étant indirectement obtenue par fixation de la pièce de raccord 56 sur la traverse 12 et de la pièce de fixation 82 sur la traverse 12. Dans ce cas, la pièce de raccord 56 et la pièce de fixation 82 peuvent toutefois coopérer, par exemple par réception d’un relief saillant de l’une dans un logement de l’autre, pour limite voire empêcher un mouvement selon au moins un degré de liberté, de la pièce de raccord 56 par rapport à la pièce de fixation 82. [0080] According to another alternative, the connecting part 56 and the fixing part 82 are not fixed directly to each other, the fixing of these parts being indirectly obtained by fixing the connecting part 56 to the crosspiece 12 and the fixing part 82 on the crosspiece 12.
