EP 1 623 879 A1 discloses a front block assembly comprising means for reinforcing a bumper skin in the form of a reinforcing beam extending between two optical block fixing brackets and serving as support to an upper edge of the bumper skin. However, such a reinforcement is not sufficient on some vehicles with more enveloping bumper skins. In addition, it is desirable that the bumper skin can fit without stress or deformation with the surrounding bodywork elements, such as optical blocks, fenders or hood of the vehicle, so that perceived quality is high. . It is an object of the invention to provide a front block assembly which has reinforcing means adapted for wraparound bumper skins, while allowing an adjustment of the bumper skin when assembled on the front face. . For this purpose, the subject of the invention is a reinforcing liner panel intended to be applied to the back of a motor vehicle bumper skin to reinforce it, characterized in that it is in one piece and comprises at least a first portion and a second reinforcing portion interconnected by a connecting zone of the flexibility panel greater than that of the first portion and the second portion. The panel according to the invention may comprise one or more of the following features: the connection zone is formed by a notch formed on one edge of the panel; - It comprises a connecting tongue spanning the notch to connect the second part to the first part; The connecting tongue has a thickness which is smaller than the thickness of the first part and the second part which it connects; the connection zone comprises a film hinge; and the first and second portions comprise a central portion for reinforcing a region of the bumper skin between optical blocks, and side reinforcing portions of bumper skin areas defining a receiving space therebetween. an optical block, each lateral part being connected by a connecting zone to the central part. The invention also relates to a front block assembly for a motor vehicle, comprising: a front face intended to be fixed to the front of a motor vehicle structure; two optical block fixing brackets fixed on the front face and distant from each other; and 10 - a bumper skin covering the front face, characterized in that it further comprises a panel as described above for reinforcing at least an upper portion of the bumper skin. The front block assembly according to the invention may include the feature that the first portion of the panel extends between the optical block attaching brackets, the panel having second portions provided for reinforcing areas of the bumper skin. -choc intended to border optical blocks. The invention also relates to a motor vehicle, characterized in that it comprises a front block assembly as described above. The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended drawings, in which: FIG. 1 is a diagrammatic perspective exploded view of a front block assembly for a motor vehicle according to the invention; Figure 2 is a view illustrating in detail a reinforcing liner panel of the front block assembly of Figure 1; and FIG. 3 is a view showing the section along the line III-III of FIG. 2. FIG. 1 illustrates a front vehicle block assembly 10 according to the invention. In all that follows, the terms front, rear, longitudinal, transverse, lateral, upper and lower are understood by reference to the usual orthogonal reference frame of the motor vehicles illustrated in FIG. 1, and comprising: a longitudinal axis XX, directed from the back to the front; - a transverse axis Y-Y, oriented from right to left; and - a vertical axis Z-Z, oriented from bottom to top. The assembly 10 comprises a front face 12, two optical block fixing brackets 14, a bumper skin 16, and a panel 18 forming a reinforcing lining of the bumper skin 16. The front face 12, essentially rigid and having the general shape of a frame, comprises an upper cross member, a lower cross member 22, the two crosspieces 20, 22 being substantially horizontal, and two uprights 24 extending substantially vertically between the crosspieces 20, 22. The crosspiece 20 has end portions 25 extending laterally outwardly of the frame and rearwardly. The front face 12 is adapted to be fixed to the front of a structure (not shown) of a motor vehicle.

Pour ce faire, les montants 24 sont par exemple reliés, sensiblement à mi-hauteur, à des longerons inférieurs de la structure, et les portions d'extrémité 25 sont reliées à des longerons supérieurs de la structure. Les supports 14 sont fixés de chaque côté de la face avant 12, à distance l'un de l'autre. Chaque support 14 est fixé sur un montant 24 respectif.  For this purpose, the uprights 24 are for example connected, substantially at mid-height, to lower longitudinal members of the structure, and the end portions 25 are connected to upper longitudinal members of the structure. The supports 14 are fixed on each side of the front face 12, at a distance from each other. Each support 14 is fixed on a respective amount 24.

Chaque support 14 comporte une poutre 28 possédant une extrémité 26 fixée au montant 24 correspondant, sensiblement à mi-hauteur, et s'étendant horizontalement, latéralement vers l'extérieur et vers l'arrière à partir du montant 24 correspondant. La poutre 28 de chaque support 14 est destinée à supporter un bloc optique 30, seul un des blocs optiques étant représenté sur la Figure 1. Chaque bloc optique 30 est destiné à être reçu sensiblement entre la poutre 28 correspondante et la portion 25 adjacente. La peau de pare-choc 16 est conçue pour recouvrir la face avant 12 sur toute sa largeur.  Each support 14 comprises a beam 28 having an end 26 fixed to the corresponding upright 24, substantially at mid-height, and extending horizontally, laterally outwardly and rearwardly from the corresponding upright 24. The beam 28 of each support 14 is intended to support an optical block 30, only one of the optical blocks being shown in FIG. 1. Each optical block 30 is intended to be received substantially between the corresponding beam 28 and the adjacent portion 25. The bumper skin 16 is designed to cover the front face 12 along its entire width.

La peau de pare-choc 16 est réalisée par exemple d'une seule pièce de matériau plastique, et obtenue par moulage par injection. La peau de pare-choc 16 est munie, de chaque côté, d'un évidement 32 de forme complémentaire de celle d'une partie du bloc optique 30 correspondant, et propre à recevoir celle-ci.  The bumper skin 16 is made for example of a single piece of plastic material, and obtained by injection molding. The bumper skin 16 is provided on each side with a recess 32 of shape complementary to that of a portion of the corresponding optical block 30 and adapted to receive it.

Le panneau 18 est adapté pour être appliqué sur la surface arrière (au dos) d'une partie 34 supérieure de la peau de pare-choc 16 s'étendant entre les évidements 32. Le panneau 18 est distinct des supports 14 de fixation de bloc optique.  The panel 18 is adapted to be applied to the rear surface (at the back) of an upper portion 34 of the bumper skin 16 extending between the recesses 32. The panel 18 is distinct from the block fixing brackets 14 optical.

Le panneau 18 est monobloc et comprend une partie centrale 36 allongée destinée à être appliquée sur la zone de la partie 34 se situant entre les évidements 32 de sorte que, lorsque la peau 16 et le panneau 18 sont assemblés à la face avant 12, la partie centrale 36 s'étend entre les supports 14. Le panneau 18 comprend, à chaque extrémité, deux parties latérales 38 prolongeant la partie centrale 36 latéralement vers l'extérieur, prévues pour renforcer la peau de pare-choc 16 dans des zones 40 bordant l'évidement 32 adjacent et délimitées en pointillés sur la Figure 1. Une partie latérale 38 supérieure renforce une zone 40 s'étendant au-dessus du bloc optique 30, et l'autre partie latérale 38 inférieure renforce une 15 zone 40 située au-dessous de l'évidement 32. Chaque partie latérale 38 est reliée à la partie centrale 36 par une zone de liaison 42 du panneau 18 qui présente une flexibilité supérieure à celle de la partie centrale 36 et de la partie latérale 38 correspondante. Comme on le voit mieux sur la Figure 2, chaque zone de liaison 42 est 20 formée par une encoche 44 ménagée sur un bord 46 du panneau 18 destiné à border les blocs optiques 30, entre la partie centrale 36 et la partie latérale 38 correspondante. A chaque encoche 44 est associée une languette de liaison 48 reliant la partie latérale 38 correspondante et la partie centrale 36, et enjambant 25 l'encoche 44. Les languettes de liaison 48 sont venues de matière avec le panneau 18 et présentent une épaisseur e plus faible que l'épaisseur E de la partie centrale 36 et des parties latérales 38 qu'elles relient (voir Figure 3). Le panneau 18 est réalisé d'une seule pièce, par exemple de matériau 30 plastique, et obtenu par moulage par injection. De manière connue, le panneau 18 comporte, sur sa partie centrale 36, des reliefs de rigidification.  The panel 18 is integral and comprises an elongated central portion 36 intended to be applied on the zone of the portion 34 situated between the recesses 32 so that, when the skin 16 and the panel 18 are assembled to the front face 12, the central portion 36 extends between the supports 14. The panel 18 comprises, at each end, two lateral portions 38 extending the central portion 36 laterally outward, provided to reinforce the bumper skin 16 in areas 40 bordering the adjacent recess 32 and dashed in FIG. 1. An upper side portion 38 reinforces an area 40 extending above the optical block 30, and the other lower side portion 38 reinforces an area 40 located in the area below the recess 32. Each lateral portion 38 is connected to the central portion 36 by a connecting zone 42 of the panel 18 which has a greater flexibility than that of the central portion 36 and the portion la 38 corresponding. As best seen in FIG. 2, each connecting zone 42 is formed by a notch 44 formed on an edge 46 of the panel 18 for flanking the optical blocks 30, between the central portion 36 and the corresponding lateral portion 38. Each notch 44 is associated with a connecting tongue 48 connecting the corresponding lateral portion 38 and the central portion 36, and straddling the notch 44. The connecting tongues 48 are integral with the panel 18 and have a thickness e plus weak as the thickness E of the central portion 36 and the side portions 38 that they connect (see Figure 3). The panel 18 is made in one piece, for example of plastic material, and obtained by injection molding. In known manner, the panel 18 comprises, on its central portion 36, stiffening reliefs.

Pour le montage de la face avant, le panneau 18 est fixé sur la peau de pare-choc 16 par clippage de la partie centrale 36 du panneau 18 le long du bord supérieur de la partie 34 supérieure de la peau 16. Une soudure par points est également prévue entre les parties 5 latérales 38 du panneau 18 et les zones 40 de la peau 16, de façon générale sur le pourtour des évidements 32. Les blocs optiques 30 sont fixés sur les poutres 28 et sur les ailes (non représentées) du véhicule. L'ensemble peau 16 / panneau 18 est fixé sur la face avant 12 et sur les blocs optiques 30, par exemple au niveau d'extrémités 50 de la peau 16. Les encoches 44 et les languettes de liaison 48 confèrent une certaine flexibilité localisée au panneau 18, permettant ainsi de limiter les contraintes d'assemblage entre la peau de pare-choc 16 et le panneau 18, de limiter les déformations de la peau de pare-choc 16 et d'ajuster la peau de pare-choc 16 lors de son assemblage sur la face avant 12. La zone de liaison 42 de chaque partie latérale 38 supérieure autorise un mouvement de flexion de la partie latérale 38 associée sensiblement dans un plan défini par les axes Y-Y et Z-Z comme illustré par la flèche FI, tandis que la zone de liaison 42 de chaque partie latérale 38 inférieure autorise un mouvement 20 de flexion de la partie latérale 38 associée sensiblement dans un plan défini par les axes X-X et Y-Y comme illustré par la flèche F2. La flexibilité conférée aux parties latérales 38 du panneau 18 permet un mouvement des zones 40 de la peau 16 par rapport aux blocs optiques 30 afin d'ajuster les jeux entre les bords de la peau 16 destinés à border les blocs 25 optiques 30 et ces derniers, améliorant ainsi la cohésion des différents éléments composant l'ensemble 10 de bloc avant selon l'invention. Les languettes de liaison 48 permettent d'obtenir un bon compromis flexibilité/rigidité pour chaque zone de liaison 42 du panneau 18. Grâce au panneau 18, la rigidité de la peau de pare-choc 16 est 30 accrue, notamment dans le cas d'une sollicitation verticale résultant par exemple de l'appui d'une personne sur la partie avant du véhicule. Ceci améliore la qualité perçue du véhicule.  For the mounting of the front face, the panel 18 is fixed on the bumper skin 16 by clipping the central portion 36 of the panel 18 along the upper edge of the upper portion 34 of the skin 16. A spot weld is also provided between the side portions 38 of the panel 18 and the zones 40 of the skin 16, generally around the periphery of the recesses 32. The optical blocks 30 are fixed on the beams 28 and on the wings (not shown) of the vehicle. The skin assembly 16 / panel 18 is fixed on the front face 12 and on the optical blocks 30, for example at the ends 50 of the skin 16. The notches 44 and the connecting tabs 48 confer a certain localized flexibility to the skin. panel 18, thus making it possible to limit the assembly constraints between the bumper skin 16 and the panel 18, to limit the deformations of the bumper skin 16 and to adjust the bumper skin 16 during its assembly on the front face 12. The connecting zone 42 of each upper lateral portion 38 allows a bending movement of the associated lateral portion 38 substantially in a plane defined by the axes YY and ZZ as illustrated by the arrow FI, while the connecting zone 42 of each lower lateral portion 38 allows a bending movement 20 of the associated lateral portion 38 substantially in a plane defined by the axes XX and YY as illustrated by the arrow F2. The flexibility imparted to the side portions 38 of the panel 18 allows movement of the areas 40 of the skin 16 relative to the optical blocks 30 to adjust the clearances between the edges of the skin 16 for tying the optical blocks 30 and the latter , thus improving the cohesion of the different elements composing the front block assembly 10 according to the invention. The connecting tongues 48 make it possible to obtain a good flexibility / stiffness compromise for each connection zone 42 of the panel 18. Thanks to the panel 18, the rigidity of the bumper skin 16 is increased, in particular in the case of a vertical stress resulting for example from the support of a person on the front part of the vehicle. This improves the perceived quality of the vehicle.

6 Le panneau 18 renforce également la peau 16 lors d'un choc avec un piéton, et permet de mieux amortir un tel choc pour limiter les blessures du piéton. Dans une variante, chaque zone de liaison 42 est réalisée sous la 5 forme d'une charnière film. La flexibilité des parties latérales du panneau 18, apportée par chaque zone de liaison 42, permet durant le montage de l'ensemble 10 sur la structure du véhicule, d'obtenir une déformation légère de ces parties latérales, et une qualité d'assemblage et une esthétique optimale de l'avant du véhicule, 10 constante dans le temps et ce sans opérations de reprise et d'ajustement supplémentaires postérieures à l'assemblage du véhicule. Le panneau selon l'invention permet donc de rigidifier les peaux de pare-choc enveloppantes, tout en évitant d'induire des contraintes d'assemblage dans la peau de pare-choc et en permettant un ajustement de la peau de pare- 15 choc lors de son assemblage sur la face avant.The panel 18 also strengthens the skin 16 during a shock with a pedestrian, and better dampens such a shock to limit the injury of the pedestrian. In a variant, each connecting zone 42 is made in the form of a film hinge. The flexibility of the lateral parts of the panel 18, provided by each connecting zone 42, allows during assembly of the assembly 10 on the vehicle structure, to obtain a slight deformation of these lateral parts, and a quality of assembly and an optimal aesthetics of the front of the vehicle, 10 constant in time and without additional recovery and adjustment operations subsequent to the assembly of the vehicle. The panel according to the invention therefore makes it possible to stiffen the enveloping bumper skins, while avoiding inducing assembly constraints in the bumper skin and by allowing an adjustment of the bumper skin during of its assembly on the front face.
