Description

Agencement de fixation d'enrouleur de ceinture de sécurité pour siège de véhicule automobile  Seat belt retractor fastening arrangement for a motor vehicle seat
La présente invention concerne un agencement de fixation d'enrouleur de ceinture de sécurité de siège de premier rang dans un véhicule automobile. The present invention relates to a fastening arrangement for a first seat seat belt retractor in a motor vehicle.
Les documents DE 10 2009 018 330 et F 2 948 908 font connaître des dispositifs permettant de fixer un enrouleur de ceinture de sécurité à l'intérieur de la partie inférieure d'un pied milieu de la caisse d'un véhicule automobile. Le dernier document notamment fait connaître, en figures 1 et 2, une pièce métallique dont une extrémité inférieure est fixée à une face latérale (tournée vers l'intérieur du véhicule) du bavolet sur lequel est soudé le pied milieu, tandis que l'extrémité supérieure comporte un orifice de fixation de l'enrouleur. La pièce métallique est par ailleurs pliée selon des lignes de pliure parallèles au bavolet et donc à la direction longitudinale X du véhicule. Documents DE 10 2009 018 330 and F 2 948 908 disclose devices for fixing a seat belt retractor inside the lower part of a central pillar of the body of a motor vehicle. The last document, in particular, shows, in FIGS. 1 and 2, a metal part whose lower end is fixed to a lateral face (turned towards the inside of the vehicle) of the flap on which the middle foot is welded, while the end upper has a fixing hole of the winder. The metal part is also folded along fold lines parallel to the flap and therefore to the longitudinal direction X of the vehicle.
La Demanderesse a constaté que cet agencement, satisfaisant sur le plan mécanique, pouvait faire l'objet de nuisances acoustiques constatées dans certaines conditions de conduite.  The Applicant has found that this arrangement, which is mechanically satisfactory, could be subject to acoustic nuisance noted under certain driving conditions.
Le but de l'invention est de remédier à cette situation et de proposer un agencement de fixation qui ne s'accompagne pas de ces nuisances acoustiques. The object of the invention is to remedy this situation and to propose a fixing arrangement which is not accompanied by these acoustic nuisances.
Afin d'atteindre ce but, des recherches et des essais de la Demanderesse ont montré que ces nuisances trouvaient leur source dans un bruit de cliquetis qui se faisait entendre dans l'enrouleur, dû à des mouvements intempestifs de la bille de blocage contenue dans l'enrouleur. La Demanderesse est parvenue à résoudre le problème de l'invention grâce à un agencement de fixation d'enrouleur sur un bavolet support de pied milieu d'une caisse automobile, le bavolet comportant une face interne verticale et une face supérieure horizontale, l'agencement comprenant une plaque métallique comportant une extrémité inférieure fixée à ladite face interne de bavolet et une extrémité supérieure dotée d'un point de fixation d'enrouleur, caractérisé en ce que la plaque est une plaque rigide sensiblement plane, en dehors d'au moins une patte anti-rotation formée orthogonalement à l'extrémité inférieure de plaque et fixée sur la face supérieure du bavolet. In order to achieve this goal, researches and tests of the Applicant have shown that these nuisances found their source in a rattling noise that was heard in the reel, due to inadvertent movements of the locking ball contained in the reel. The Applicant has been able to solve the problem of the invention by means of a reel fastening arrangement on a support lip of the center pillar of a car body, the cap having a vertical inner face and a horizontal upper face, the arrangement comprising a metal plate having a lower end attached to said inner flap face and an upper end having a fastening point retractor, characterized in that the plate is a substantially flat rigid plate, outside at least one anti-rotation tab formed orthogonally to the lower plate end and fixed on the upper face of the flap.
La Demanderesse s'est en effet aperçu qu'une telle mesure permettait d'augmenter suffisamment l'inertance (raideur) de la fixation de l'enrouleur dans la direction transversale Y, laquelle est assez sollicitée en raison de la fixation en porte-à-faux de l'enrouleur sur l'extrémité supérieure de la plaque. Cette augmentation de raideur en Y permet de supprimer le bruit de cliquetis de l'enrouleur. The Applicant has in fact realized that such a measure makes it possible to increase sufficiently the inertness (stiffness) of the fastening of the winder in the transverse direction Y, which is sufficiently stressed due to the fastening in the door to -faux of the retractor on the upper end of the plate. This increase in stiffness in Y makes it possible to suppress the rattling noise of the winder.
De préférence, il est prévu deux pattes de fixation de part et d'autre de l'extrémité inférieure de la plaque. Preferably, there are provided two fastening tabs on either side of the lower end of the plate.
Avantageusement, la fixation sur la face interne du bavolet est une fixation par vis et la fixation de la ou des pattes anti-rotation sur la face supérieure du bavolet est une fixation par soudure. Advantageously, the fixing on the inner face of the flap is a screw fixing and the attachment of the anti-rotation tab or tabs on the upper face of the flap is a welding attachment.
Avantageusement, la plaque est dotée sur sa surface d'une nervure de rigidification, par exemple en V. Advantageously, the plate is provided on its surface with a stiffening rib, for example V.
D'autres caractéristiques et avantages de l'invention ressortiront de la description suivante d'un exemple de réalisation. Il sera fait référence à la figure unique qui représente l'agencement de fixation de l'invention. Other features and advantages of the invention will emerge from the following description of an exemplary embodiment. Reference will be made to the single figure which shows the fastening arrangement of the invention.
On y voit représenté assez schématiquement une partie de côté de caisse de véhicule montrant un pied milieu 1 entre deux ouvertures latérales avant et arrière de véhicule 2 et 3. Le bas du pied milieu 1 est soudé sur le bavolet longitudinal 4 qui fait partie des longerons de la structure de soubassement du véhicule, non représentée. Le bavolet 4 comprend une face verticale interne 5 et une face supérieure horizontale 6, éventuellement bordée du côté externe par une bordure relevée verticale 6a. On voit aussi un pontet 7 de fixation de siège fixé lui-même à la face interne 5 du bavolet 4 et au plancher 8 du véhicule. L'agencement de fixation de l'invention comprend essentiellement la plaque métallique 10, par exemple en acier, sensiblement plane, en dehors d'une nervure de rigidification 1 1 de faible hauteur, par exemple en V arrondi, disposée sur sa surface en son centre, et de deux pattes pliées anti-retour 12. La nervure 1 1 est facilement obtenue par emboutissage de la plaque, de faible profondeur, et les pattes pliées 12 peuvent être formées dans une presse plieuse. La plaque 10 comporte une extrémité inférieure centrale arrondie 13, dans laquelle un trou 14 permet de passer une vis non représentée pour la fixation de la plaque sur la face interne 5 du bavolet 4. Les deux pattes pliées 12 sont de part et d'autre de l'extrémité inférieure 13 et sont soudées à la surface supérieure 6 du bavolet, assurant ainsi une fonction anti-rotation de la plaque 10 et également une certaine raideur en direction Y. Par ailleurs, les deux pattes pliées 12 permettent également de répondre aux exigences des différentes réglementations, notamment européenne, sur l'accrochage des ceintures, en répartissant les efforts entre la vis et les deux pattes pliées soudées 12. La plaque 10 se poursuit en hauteur par une extrémité 15 dont la largeur s'amenuise, et elle est dotée d'un ou plusieurs moyens de fixation 16 (par exemple un orifice) d'un enrouleur (esquissé en 17), qui sera donc maintenu en porte-à-faux sur la plaque 10 et sera caché à la vue par une doublure (non représentée) prévue sur le pied milieu 1. There is shown schematically a vehicle body side portion showing a center leg 1 between two front and rear lateral openings of vehicle 2 and 3. The bottom of the middle leg 1 is welded to the longitudinal flap 4 which is part of the side members of the underbody structure of the vehicle, not shown. The flap 4 comprises an inner vertical face 5 and a horizontal upper face 6, optionally bordered on the outer side by a vertical raised edge 6a. We also see a bracket 7 of seat fastening itself fixed to the inner face 5 of the flap 4 and the floor 8 of the vehicle. The fastening arrangement of the invention essentially comprises the metal plate 10, for example made of steel, which is substantially flat, apart from a stiffening rib 11 of low height, for example a rounded V, disposed on its surface in its shape. center, and two folded tabs 12. The rib 1 1 is easily obtained by stamping the plate, shallow, and the folded tabs 12 may be formed in a press brake. The plate 10 has a rounded central bottom end 13, in which a hole 14 makes it possible to pass a not shown screw for fastening the plate to the internal face 5 of the flap 4. The two folded tabs 12 are on both sides of the lower end 13 and are welded to the upper surface 6 of the flap, thus providing an anti-rotation function of the plate 10 and also a certain stiffness in the Y direction. Moreover, the two folded tabs 12 also make it possible to respond to the requirements of the various regulations, in particular European regulations, on the fastening of the belts, by distributing the forces between the screw and the two welded folded tabs 12. The plate 10 continues in height by an end 15 whose width is diminishing, and is provided with one or more fastening means 16 (for example an orifice) of a winder (sketched at 17), which will thus be held cantilevered on the plate 10 and will be hidden at the seen by a lining (not shown) provided on the middle leg 1.
L'agencement conforme à l'invention, en augmentant la raideur du support d'enrouleur, s'oppose à l'entrée en résonnance de la bille à l'intérieur de l'enrouleur et met un terme au cliquetis intempestif observé jusque-là. The arrangement according to the invention, by increasing the stiffness of the retractor support, opposes the entry into resonance of the ball inside the reel and ends the untimely rattling observed until then .
