Description

AGENCEMENT DE FIXATION D'UN ELEMENT DE VEHICULE AUTOMOBILE ARRANGEMENT FOR FASTENING A MOTOR VEHICLE ELEMENT
La présente invention concerne un agencement de fixation d'un élément de véhicule automobile et plus particulièrement un agencement dans lequel cet élément est monté sur un moyen structurel du véhicule par l'intermédiaire d'un boîtier qui est solidaire de ce moyen structurel et qui forme une cage dans laquelle un écrou de fixation est monté avec jeu, cet écrou pouvant collaborer avec une vis de fixation pour le montage de l'élément, de sorte que le jeu de l'écrou permet de rattraper les dispersions de ce montage.The present invention relates to a fastening arrangement of a motor vehicle element and more particularly to an arrangement in which this element is mounted on a structural means of the vehicle via a housing which is integral with this structural means and which forms a cage in which a fixing nut is mounted with clearance, this nut being able to collaborate with a fastening screw for mounting the element, so that the play of the nut makes it possible to catch the dispersions of this assembly.
Il est connu des agencements de ce type pour la fixation de siège automobile, dans lequel l'écrou, dit écrou flottant est centré mais non fixé dans une cage. Cet écrou présente donc des degrés de liberté permettant l'ajustement entre la vis rendu par la suite solidaire du siège et l'écrou. Afin de ne pas autoriser une liberté de rotation qui empêcherait la stricte immobilisation du fauteuil une fois monté, l'écrou présente une forme sensiblement rectangulaire de sorte que la rotation soit empêchée par Ic contact entre l'écrou et les parois de la cage. Cette cage et l'écrou associé sont montés sur le véhicule et rendus solidaires du plancher. Avant le montage définitif des sièges, le véhicule passe dans un bain de cataphorèse. Un inconvénient majeur de l'état de l'art est que l'écrou et la cage sont collés par ce bain, et que iors du vissage de la vis dans l'écrou, un effort important est nécessaire pour décoller ces deux éléments, ce qui peut provoquer un à coup entre l'écrou et la vis et abîmer le pas de vis.It is known arrangements of this type for the attachment of car seat, wherein the nut, said floating nut is centered but not fixed in a cage. This nut has thus degrees of freedom for the adjustment between the screw made by a joint following the siege and nut. In order not to allow a freedom of rotation that would prevent the rigid immobilization of the chair once mounted, the nut has a substantially rectangular shape so that the rotation is prevented by the contact between the nut and the walls of the cage. This cage and the associated nut are mounted on the vehicle and secured to the floor. Before the final assembly of the seats, the vehicle goes into a cataphoresis bath. A major disadvantage of the state of the art is that the nut and the cage are bonded by this bath, and that when screwing the screw in the nut, a significant effort is required to take off these two elements, this which can cause a sudden blow between the nut and the screw and damage the thread.
Un des objectifs de l'invention est donc de proposer un agencement de fixation du type décrit ci dessus qui améliore le montage de l'élément sur le moyen structurel, par exemple le montage du siège sur le plancher, et qui en particulier minimise l'effort nécessaire pour le vissage.One of the objectives of the invention is therefore to propose a fixing arrangement of the type described above which improves the mounting of the element on the structural means, for example the mounting of the seat on the floor, and which in particular minimizes the effort required for screwing.

• l'écrou présente une forme sensiblement rectangulaire et en ce que les éléments nervures en forment les diagonales, • la cage comporte d'une part un élément support formant la partie inférieure de la cage et sur lequel l'écrou mobile est positionné, et d'autre part un élément de renfort formant la partie supérieure de la cage, cet élément de renfort présentant un orifice apte à laisser le passage à la vis de fixation solidaire du siège, • les dimensions de l'écrou mobile sont telles que cet écrou est bloqué en rotation par au moins une paroi de la cage formée par l'élément de renfort et/ou par l'élément support,The nut has a substantially rectangular shape and in that the rib elements form the diagonals, the cage comprises on the one hand a support element forming the lower part of the cage and on which the movable nut is positioned, and on the other hand a reinforcing element forming the upper part of the cage, this reinforcing element having an orifice adapted to allow the passage to the fixed fastening screw of the seat, the dimensions of the movable nut are such that this nut is prevented from rotating by at least one wall of the cage formed by the reinforcing member and / or the support member,
• au moins une paroi de la cage formée par l'élément de renfort et/ou par l'élément support présente des éléments nervures. L'invention vise à protéger également un véhicule automobile comprenant un siège monté par l'intermédiaire d'au moins un dispositif de fixation selon l'invention.At least one wall of the cage formed by the reinforcing element and / or by the support element has rib elements. The invention aims to also protect a motor vehicle comprising a seat mounted via at least one fastening device according to the invention.
D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui suit pour la compréhension de laquelle on se reportera aux dessins annexés dans lesquels :Other features and advantages of the invention will appear on reading the detailed description which follows for the understanding of which reference will be made to the appended drawings in which:

Dans la description qui va suivre, on adoptera à titre non limitatif une orientation longitudinale, verticale et transversale selon l'orientation traditionnellement utilisée dans l'automobile et indiquée par le trièdre L, V, T de la figure 1.In the following description, a longitudinal, vertical and transverse orientation will be adopted in a nonlimiting manner according to the orientation conventionally used in the automobile and indicated by the trihedron L, V, T of FIG.
La description qui va suivre divulgue un mode de réalisation particulier de l'invention dans lequel l'agencement de fixation est relatif à la fixation d'un siège. Il sera compris que d'autres éléments, dont le montage nécessite un rattrapage des dispersions, du véhicule peuvent bénéficier de cet agencement de fixation selon l'invention.The following description discloses a particular embodiment of the invention in which the fastening arrangement relates to the attachment of a seat. It will be understood that other elements, the assembly of which requires a retrieval of dispersions, the vehicle can benefit from this fastening arrangement according to the invention.
La figure 1 représente une moitié gauche du soubassement central 1 d'un véhicule, délimité vers l'extérieur du véhicule par le bavolet gauche 2 et vers l'intérieur du véhicule par un tunnel 3. Par symétrie par rapport à ce tunnel 3, l'invention est également applicable à la moitié droite du soubassement central. Toutefois, pour des soucis de simplification, seule la moitié gauche et les fixations du siège correspondant seront décrits.1 shows a left half of the central base 1 of a vehicle, delimited at the outside of the vehicle by the left sill 2 and inward of the vehicle by a tunnel 3. By symmetry with respect to the tunnel 3, the The invention is also applicable to the right half of the central bed. However, for the sake of simplification, only the left half and the attachments of the corresponding seat will be described.
Ce soubassement central est renforcé par deux traverses de plancher central 4 et 5, qui sont soudées au plancher 6. Ces deux traverses 4 et 5, moyens structurels du véhicule, permettent la fixation d'un siège.This central base is reinforced by two crosspieces central floor 4 and 5, which are welded to the floor 6. These two cross members 4 and 5, structural means of the vehicle, allow the attachment of a seat.
Longitudinalement, deux fixations avant 7 du siège sont montées sur le moyen structurel du véhicule formé par la traverse avant de plancher 4. et deux fixations arrière 8 de ce siège sont montées sur le moyen structurel du véhicule formé par la traverse arrière de plancher 5. Les fixations avant 7 et arrière 8 du siège situées du côté du tunnel 3 sont réalisées par un ensemble sans jeu. Il est alors préférable que les fixations avant 7 et arrière 8 du siège situées du côté du bavolet 2 présentent un jeu de montage pour prendre en compte les dispersions induites lors de la mise en position du siège sur les éléments structurels 4 et 5 du véhicule.Longitudinally, two front fasteners 7 of the seat are mounted on the structural means of the vehicle formed by the front floor cross member 4. and two rear fasteners 8 of this seat are mounted on the structural means of the vehicle formed by the rear floor cross member 5. The front fasteners 7 and rear 8 of the seat located on the side of the tunnel 3 are formed by a set without clearance. It is then preferable that the front and rear fasteners 8 of the seat located on the side of the flap 2 have a mounting set to take in account the dispersions induced during the positioning of the seat on the structural elements 4 and 5 of the vehicle.
Ce jeu de montage est assuré par la présence d'un écrou mobile 40 dans une cage 20, formée dans un boîtier 10. Tel que représenté à la figure 2, ce boîtier 10 peut être rapporté sur un moyen structurel 4, 5 du véhicule, ou le boîtier 10 et le moyen structurel 4, 5 peuvent être réalisés d'une seule et même pièce. A titre d'exemple, à la figure 2. un boîtier rapporté 10a est utilisé pour les fixations du siège sur la traverse de plancher avant 4, et la traverse de plancher arrière 5 intègre un boîtier de fixation 10b. Il sera compris que cette disposition pourrait être inversée, ou que quatre boîtiers rapportés 10a pourraient être utilisés. Tel que représenté à la figure 2. chaque configuration est conforme à la présente invention dès lors que les fixations extérieures du siège, proches du bavolet 2, sont des dispositifs de fixations présentant un jeu de montage.This mounting clearance is provided by the presence of a movable nut 40 in a cage 20, formed in a housing 10. As shown in Figure 2, this housing 10 can be attached to a structural means 4, 5 of the vehicle, or the casing 10 and the structural means 4, 5 can be made of a single piece. By way of example, in FIG. 2, an insert box 10a is used for the seat fasteners on the front floor crossmember 4, and the rear floor crossmember 5 incorporates a fastening box 10b. It will be understood that this provision could be reversed, or that four reported cases 10a could be used. As shown in Figure 2. each configuration is according to the present invention since the outer fasteners of the seat, close to the flap 2, are fasteners having a mounting set.
Une cage 20 est disposée à l'intérieur du boîtier de fixation 10, que ce boîtier soit intégré à la traverse ou rapporté sur cette traverse. A titre d'exemple, une cage 20 est positionnée selon un sens sensiblement longitudinal, soudée sur la traverse de plancher avant 4 ou arrière 5, et au moins recouverte par le boîtier de fixation 10 correspondant à cette traverse.A cage 20 is disposed within the fixing housing 10, this housing is integrated into the transom or attached to the crossmember. By way of example, a cage 20 is positioned in a substantially longitudinal direction, welded to the front floor beam 4 or rear 5, and at least covered by the fixing housing 10 corresponding to this cross member.
Les figures 3 et 4 représentent un mode de réalisation d'une cage 20 selon l'invention. Un élément support 21 forme la partie inférieure de la cage 20. Cet élément support 21 est obtenu par le pliage multiple d'une lame de telle sorte que l'élément support 21 présente une forme en escalier. Un premier pliage à quatre vingt dix degrés détermine la liaison entre Ia zone principale 22 de l'élément support 21 et un premier bord tombé 23, descendant par rapport à la zone principale et formant une première patte de fixation. Un second pliage à quatre vingt dix degrés détermine la liaison entre l'extrémité, opposée au premier bord tombé 23, de la zone principale 22 de l'élément support 21 et un second bord tombé 24, montant par rapport à la zone principale 22. Un troisième pliage à quatre vingt dix degrés détermine la liaison entre le second bord tombé 24 et une seconde patte de fixation 25, sensiblement parallèle à la zone principale 22 de l'élément support 21. Des rainures 26 sont réalisées dans l'élément support 21 à chaque arête de pliage, afin que l'angle droit de ces pliages soient consolidés.Figures 3 and 4 show an embodiment of a cage 20 according to the invention. A support element 21 forms the lower part of the cage 20. This support element 21 is obtained by the multiple folding of a blade so that the support element 21 has a stepped shape. A first ninety-degree fold determines the connection between the main zone 22 of the support member 21 and a first fallen edge 23, descending with respect to the main zone and forming a first fastening tab. A second ninety-degree fold determines the connection between the end, opposite the first dropped edge 23, of the main zone 22 of the support member 21 and a second fallen edge 24, rising relative to the main zone 22. A third ninety-degree fold determines the connection between the second dropped edge 24 and a second fastening tab 25, substantially parallel to the main zone 22 of the support member 21. Grooves 26 are formed in the support member 21 at each folding edge, so that the right angle of these folds are consolidated.
Une partie supérieure de cette cage 20 est formé par un élément de renfort 27, qui présente à ses extrémités des formes complémentaires de l'élément support 21 , pour que l'élément support 21 et l'élément de renfort 27 soient soudés au niveau des pattes de fixations 23 et 25 de F élément support 21. La cage 20 formée par ces deux parties présente un espace creux 28, logement dans lequel est mobile un écrou 40.An upper part of this cage 20 is formed by a reinforcing element 27, which at its ends has complementary shapes of the support member 21, so that the support member 21 and the reinforcing member 27 are welded at the fixing lugs 23 and 25 of support member F 21. The cage 20 formed by the two parts has a hollow space 28 housing in which a nut 40 is movable.
La zone principale 22 de l'élément support 21 correspond à la partie inférieure du logement 28 de l'écrou mobile 40. Cette zone 22 présente un orifice 29 dans lequel vient se positionner un col 41 de l'écrou 40, ce col 41 étant une portion cylindrique en saillie de la base 42 de l'écrou 40. L'orifice 29 de la zone principale 22 est de diamètre plus important que le diamètre du col 41 de l'écrou 40. Une légère translation est ainsi autorisée pour l'écrou mobile 40, avant que le col 41 de l'écrou 40 ne soit bloqué par le bord de l'orifice 29.The main zone 22 of the support element 21 corresponds to the lower part of the housing 28 of the movable nut 40. This zone 22 has an orifice 29 in which a collar 41 of the nut 40 is positioned, this collar 41 being a cylindrical portion projecting from the base 42 of the nut 40. The orifice 29 of the main zone 22 is of greater diameter than the diameter of the neck 41 of the nut 40. A slight translation is thus authorized for the mobile nut 40, before the neck 41 of the nut 40 is blocked by the edge of the orifice 29.
Un trou 30 est prévu dans l'élément de renfort 27 pour laisser le passage à une vis de fixation solidaire du siège. Le mouvement de translation autorisé de l'écrou mobile 40 permet un ajustement de la position de cet écrou 40 de sorte qu'il se retrouve sous le trou 30 de l'élément de renfort 27 et à la verticale de la vis de fixation. Cet ajustement permet de rattraper les dispersions de montage du siège et de pouvoir aligner la vis, le passage 30 de vis aménagé dans la cage 20 et l'écrou mobile 40 pour permettre la fixation du siège sur le moyen structurel 4. 5 du véhicule.A hole 30 is provided in the reinforcing element 27 to allow passage to a fastening screw secured to the seat. The translational movement permitted of the movable nut 40 permits adjustment of the position of the nut 40 so that it is found under the hole 30 of the reinforcing member 27 and vertically above the screws. This adjustment makes it possible to catch up with the mounting dispersions of the seat and to be able to align the screw, the screw passage provided in the cage 20 and the movable nut 40 to enable the seat to be attached to the structural means 4 of the vehicle.
A titre d'exemple, le siège est muni de deux rails sur lequel il peut coulisser. Ces rails sont posés sur les boîtiers 10 et présentent des alésages pour que les vis de fixation puissent solidariser ces rails sur les boîtiers de fixation 10. Le siège est coulissé dans sa position extrême avant ou extrême arrière, selon que l'opérateur visse les rails du siège sur le boîtier arrière ou le boîtier avant.For example, the seat is provided with two rails on which it can slide. These rails are placed on the housings 10 and have bores so that the fastening screws can secure these rails to the fastening boxes 10. The seat is slid in its extreme front or rear end position, depending on whether the operator screws the rails seat on the rear or front housing.
Les dimensions de l'écrou mobile 40 et de l'espace creux 28 aménagé entre l'élément support 21 et l'élément de renfort 27 sont telles que l'écrou mobile 40 ne peut tourner sur lui même, les faces 43 de l'écrou 40 entrant dans ce cas en contact avec les parois 31 de l'espace creux 28 formé par l'élément support 21 et l'élément de renfort 27. 11 sera compris que cette fonction anti¬ rotation peut être réalisée par un contact unique entre l'écrou 40 et une paroi 31 de l'élément de renfort 27, ou, dans une variante qui permet à la cage 20 de mieux tenir les efforts de couple du vissage, la fonction anti-rotation peut être réalisée par un double contact entre l'écrou 40 et une paroi de l'élément de renfort 27 et une paroi 31 de l'élément support 21.The dimensions of the movable nut 40 and the hollow space 28 provided between the support member 21 and the reinforcing member 27 are such that the nut 40 mobile can turn on itself, the faces 43 of the nut 40 used in this case in contact with the walls 31 of the cavity 28 formed by the support 21 and the element member 27. reinforcement 11 will understood that anti¬ rotation function can be achieved by a single contact between the nut 40 and a wall 31 of the reinforcing element 27, or, in a variant that allows the cage 20 to better withstand the torque forces of the screwing, the anti-rotation function can be achieved by a double contact between the nut 40 and a wall of the reinforcing element 27 and a wall 31 of the support element 21.
Tel que représenté à la figure 5, l'écrou 40 présente une forme sensiblement rectangulaire. Il est formé plus précisément d'une base 42 sensiblement parallélépipède, dont une face 44 est munie d'un col cylindriqueAs shown in Figure 5, the nut 40 has a substantially rectangular shape. It is more precisely formed of a substantially parallelepiped base 42, one face 44 of which is provided with a cylindrical neck
41 faisant saillie de cette base 42. Comme cela a été décrit plus haut, ce col 41 présente un diamètre approprié pour permettre un léger mouvement de translation de l'écrou 40 par rapport à l'élément support 21 de la cage 20. Il présente également une hauteur suffisante pour assurer un arrêt en translation lorsque le col 41 entre en contact avec l'orifice 29 formé dans l'élément support 21 de la cage 20.41 as it has been described above, this neck 41 has a suitable diameter to allow a slight translational movement of the nut 40 relative to the support member 21 of the cage 20. It presents also a height sufficient to ensure a translation stop when the neck 41 comes into contact with the orifice 29 formed in the support member 21 of the cage 20.
Des éléments nervures 45 sont disposés sur au moins la face 44 de l'écrou 40 qui repose sur la zone principale 22 de l'élément support 21. Ces éléments nervures 45 permettent de ne générer qu'une surface de contact minime entre l'écrou mobile 40 et la cage 20. Le passage du véhicule dans un bain de cataphorèse n'entraîne alors le collage que d'une bande de contact 46 entre l'écrou 40 et la cage 20, et l'opérateur réalisant le montage du siège peut par la suite décoller ces deux éléments par la simple action de vissage dans le boîtier de fixation 10. Le fait que l'écrou 40 et la cage 20 ne soient collés que par les bandes de contact 46 permet de conserver, après cataphorèse, l'écrou 40 dans un plan sensiblement parallèle au plan de la zone principale 22 de la cage 20. On évite ainsi une prise en biais de la vis de fixation dans l'écrou 40 lors du montage.Rib elements 45 are disposed on at least the face 44 of the nut 40 which rests on the main zone 22 of the support member 21. These rib elements 45 allow to generate only a minimal contact surface between the nut mobile 40 and the cage 20. The passage of the vehicle in a cataphoresis bath then causes the bonding only a contact strip 46 between the nut 40 and the cage 20, and the operator carrying out the assembly of the seat can thereafter take off these two elements by the simple action of screwing in the fixing housing 10. The fact that the nut 40 and the cage 20 are glued only by the contact strips 46 can maintain, after cataphoresis, the nut 40 in a plane substantially parallel to the plane of the main zone 22 of the 20. This avoids a biasing of the fixing screw in the nut 40 during assembly.
Il sera compris que des éléments nervures 45 peuvent être positionnés sur d'autres faces de l'écrou 40, et en particulier les faces situées en regard des parois 31 de la cage 20. A titre de variante, tel que représenté à la figure 4, des seconds éléments nervures 33 peuvent être portés par les parois 31 de la cage 20, l'objectif d'une résistance moindre au décollage après cataphorèse restant le même.It will be understood that rib elements 45 can be positioned on other faces of the nut 40, and in particular the faces facing the walls 31 of the cage 20. Alternatively, as shown in Figure 4 second rib members 33 may be carried by the walls 31 of the cage 20, the objective of a lower resistance to take-off after cataphoresis remaining the same.
A titre d'exemple, ces nervures 45 forment les diagonales de l'écrou mobile 40. Il sera compris qu'elles pourraient également être parallèles, ou perpendiculaires. Tel que représenté aux figures 4 et 5, une disposition des éléments nervures 45 en diagonale peut être prise en combinaison avec un embouti 32 réalisé sur l'élément support 21 vers l'intérieur de l'espace creuxFor example, these ribs 45 form the diagonals of the movable nut 40. It will be understood that they could also be parallel or perpendicular. As shown in Figures 4 and 5, an arrangement of the ribs 45 diagonally can be taken in combination with a stamped 32 made on the support member 21 towards the interior of the hollow space
28 de la cage 20. Cet combinaison permet d'obtenir des contacts ponctuels, et en l'occurrence un contact à quatre points, entre la face nervurée 44 de l'écrou mobile 40 et la cage 20. La résistance au décollage après cataphorèse en est d'autant moins forte.28 of the cage 20. This combination makes it possible to obtain point contacts, and in this case a four-point contact, between the ribbed face 44 of the movable nut 40 and the cage 20. The resistance to take-off after cataphoresis is even less strong.
L'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. The invention is not limited to the embodiment described and illustrated which has been given by way of example.
