Then, a transverse engagement of the side brackets of the bumper skin can be carried out. This commitment will be described in this description.
Le presseur 12 est apte à rester dans une position engagée avec le rebord 4.1 au moyen des pions 14. Préférentiellement, le maintien en position du presseur 12 sur l’aile 4 est réalisé au moyen d’un crochet élastique 16 qui s’étend depuis la face 12 et qui est apte à se déformer pour assurer une retenue avec le rebord 4.1 dès l’insertion des pions 14 à travers les trous 4.3 de centrage. The presser 12 is able to remain in a position engaged with the rim 4.1 by means of the pins 14. Preferably, maintaining the presser 12 in position on the wing 4 is achieved by means of an elastic hook 16 which extends from the face 12 and which is able to deform to ensure retention with the rim 4.1 as soon as the pins 14 are inserted through the centering holes 4.3.
Dans cette configuration, les crosses latérales comprenant chacune, un retour transversal (non représenté à la figure 2) peuvent s’engager avec le rebord 4.1 . De préférence, le véhicule automobile comprend deux presseurs 12 distincts et configurés pour s’engager avec le rebord 4.1 des ailes 4. Chaque presseur 12 peut être obtenu à partir d’un moulage de matériau plastique. Le presseur 12 permet avantageusement d’absorber les efforts en cas de choc frontal de manière à éviter d’endommager les optiques avant et les ailes latérales 4. In this configuration, the lateral brackets each comprising a transverse return (not shown in Figure 2) can engage with the rim 4.1. Preferably, the motor vehicle comprises two separate pressers 12 configured to engage with the edge 4.1 of the wings 4. Each presser 12 can be obtained from a molding of plastic material. The presser 12 advantageously absorbs the forces in the event of a frontal impact so as to avoid damaging the front headlights and the side wings 4.
Alternativement, les presseurs 12 peuvent faire partie intégrante d’une partie de renfort de la peau de pare-chocs, ladite partie de renfort étant distincte des crosses latérales. A cet effet, le retour transversal des crosses peut être ajusté suivant la direction transversale. Alternatively, the pressers 12 can form an integral part of a reinforcing part of the bumper skin, said reinforcing part being distinct from the side brackets. For this purpose, the transverse return of the stocks can be adjusted in the transverse direction.
Les figures 3 et 4 représentent, respectivement, une vue en perspective des pions supérieur et inférieur du presseur. Figures 3 and 4 represent, respectively, a perspective view of the upper and lower pins of the presser.
En référence aux figures 3 et 4, on peut voir que les pions 14 sont identiques et comprennent chacun la portion distale 14.1 et une portion proximale 14.2 comprenant une épaisseur réduite par rapport à la portion distale 14.1 . With reference to Figures 3 and 4, it can be seen that the pins 14 are identical and each comprise the distal portion 14.1 and a proximal portion 14.2 comprising a reduced thickness compared to the distal portion 14.1.
En effet, la portion distale 14.1 présente une augmentation d’épaisseur par rapport à la portion proximale 14.2 de manière à former une face de retenue 15 du retour transversal de la peau de pare-chocs. Indeed, the distal portion 14.1 has an increase in thickness compared to the proximal portion 14.2 so as to form a retaining face 15 of the transverse return of the bumper skin.
La portion proximale 14.1 comprend, dans cette configuration, deux faces parallèles correspondant à la face 12.1 du presseur 12 et à la face de retenue 15 appartenant à la portion distale 14.1 . The proximal portion 14.1 comprises, in this configuration, two parallel faces corresponding to the face 12.1 of the presser 12 and to the retaining face 15 belonging to the distal portion 14.1.
Avantageusement, la portion proximale 14.1 est délimitée par les deux faces 12.1 et 15, est configurée pour loger, à la fois, le rebord de l’aile et le retour transversal de la peau. Advantageously, the proximal portion 14.1 is delimited by the two faces 12.1 and 15, is configured to accommodate both the edge of the wing and the transverse return of the skin.
A cet égard, la face de retenue 15 présente un espacement e avec la face 12.1 préférentiellement compris entre 1 et 4 mm, et plus préférentiellement égal à 3,5 mm. In this regard, the retaining face 15 has a spacing e with the face 12.1 preferably between 1 and 4 mm, and more preferably equal to 3.5 mm.
De préférence, la portion proximale 14.1 comprend un évidement 12.2 dans le presseur 12 au pied du pion 14 permettant avantageusement le démoulage d’une portion intérieure (suivant la direction transversale) et de faciliter le passage du retour transversal des crosses latérales. Le presseur 12 comprend, en outre, des nervures 18 de guidage s’étendant suivant la direction d’ajustement transversal de la peau de pare-chocs et sont dimensionnées pour mettre en contrainte et plaquer longitudinalement le retour transversal des crosses latérales contre la face de retenue 15 du pion 14 de centrage. Les nervures 18 permettent ainsi d’assurer un montage sans jeu du rebord et du retour transversal entre la face 12.1 et la face de retenue 15. Preferably, the proximal portion 14.1 comprises a recess 12.2 in the presser 12 at the foot of the pin 14 advantageously allowing the demoulding of an interior portion (in the transverse direction) and facilitating the passage of the transverse return of the lateral stocks. The presser 12 further comprises guide ribs 18 extending in the direction of transverse adjustment of the bumper skin and are dimensioned to constrain and longitudinally press the transverse return of the lateral brackets against the face of retainer 15 of centering pin 14. The ribs 18 thus make it possible to ensure clearance-free mounting of the rim and the transverse return between the face 12.1 and the retaining face 15.
La partie gauche de la figure 5 représente une vue en perspective du retour transversal 6.2 de la peau 6 de pare-chocs, et la partie droite de la figure 5 représente schématiquement l’engagement transversal du retour transversal 6.2 avec les pions 14 de centrage. The left part of Figure 5 represents a perspective view of the transverse return 6.2 of the bumper skin 6, and the right part of Figure 5 schematically represents the transverse engagement of the transverse return 6.2 with the centering pins 14.
On peut voir que le retour transversal 6.2 de la crosse 6.1 comprend deux encoches 20 et 22 débouchant transversalement vers l’intérieur du véhicule automobile (suivant la direction d’ajustement), chacune étant configurée pour chevaucher la portion proximale 14.1 du pion 14 correspondant. It can be seen that the transverse return 6.2 of the stock 6.1 comprises two notches 20 and 22 opening transversely towards the interior of the motor vehicle (in the direction of adjustment), each being configured to overlap the proximal portion 14.1 of the corresponding pin 14.
Les deux encoches 20 et 22 présentent une portion proximale 24 avec deux bords 24.1 parallèles. The two notches 20 and 22 have a proximal portion 24 with two parallel edges 24.1.
L’encoche supérieure 20 comprend une portion distale 26 présentant une largeur s’évasant, formant deux bords 26.1 divergents, suivant la direction d’ajustement transversal de la peau 6 de pare-chocs, dans un sens E d’engagement avec le pion 14 de centrage correspondant. The upper notch 20 comprises a distal portion 26 having a flaring width, forming two diverging edges 26.1, following the direction of transverse adjustment of the bumper skin 6, in a direction E of engagement with the pin 14 corresponding centering.
Le montage de la peau de pare-chocs 6 sur l’aile (non représentée ici) du véhicule automobile se fait par l’engagement transversal E de chacune des deux encoches 20 et 22 avec les pions 14 de centrage. The assembly of the bumper skin 6 on the wing (not shown here) of the motor vehicle is done by the transverse engagement E of each of the two notches 20 and 22 with the centering pins 14.
Il est à noter que le presseur 12 est préalablement monté sur le rebord d’aile et les pions 14 traversant les trous de centrage. Le rebord n’a pas été illustré à la partie droite de la figure 4 de manière à faciliter la lecture de la figure. It should be noted that the presser 12 is previously mounted on the wing edge and the pins 14 pass through the centering holes. The edge has not been illustrated on the right side of Figure 4 so as to facilitate reading of the figure.
L’engagement des encoches 20 et 22 avec les pions peut comprendre un écartement latéral des chacune des deux crosses latérales 6.1 du véhicule automobile. The engagement of the notches 20 and 22 with the pins can include a lateral spacing of each of the two side brackets 6.1 of the motor vehicle.
Préférentiellement, le pion 14 de centrage comprend un renfort 17 correspondant à une rampe 17 s’étendant depuis la face 12.1 du presseur 12 vers la portion proximale 14.2 suivant un sens opposé à celui de l’engagement transversal E. Avantageusement, le renfort 17 permet de rigidifier la portion proximale 14.2. Preferably, the centering pin 14 comprises a reinforcement 17 corresponding to a ramp 17 extending from the face 12.1 of the presser 12 towards the portion proximal portion 14.2 in a direction opposite to that of the transverse engagement E. Advantageously, the reinforcement 17 makes it possible to stiffen the proximal portion 14.2.
Suite à l’engagement du retour transversal 6.2 avec le presseur 12 et le rebord d’aile, le vissage de l’ensemble peut être effectué. Avantageusement, le montage de la peau de pare-chocs sur le véhicule automobile est réalisé transversalement de manière simple et rapide, et cela, sans risque de dégradation des éléments de la face avant du véhicule automobile. Following engagement of the transverse return 6.2 with the presser 12 and the wing edge, the assembly can be screwed. Advantageously, the mounting of the bumper skin on the motor vehicle is carried out transversely in a simple and rapid manner, without risk of damage to the elements of the front face of the motor vehicle.
