[0001] The present invention relates to the field of motor vehicles, more particularly to the field of motor vehicle bumpers. Previous technique
[0002] The evolution of the style of current motor vehicles gives rise to more salient shapes, appreciated by motorists, particularly in the area of the optical blocks which may, for example, have a C-shape so as to present a hollow area requiring its coverage by an outgrowth of the bumper skin.
[0003] However, such a design complicates the assembly of the bumper skin on the motor vehicle, because it is necessary to ensure good clearance and final flushness of the protrusion with the optical block at the right of the hollow area, and this while ensuring durable retention of said bumper skin.
[0004] The published patent document FR 3 070 928 Al discloses a support device comprising a part having a return lug exerting a force on a lower wall directly indexed on a housing of the optical block, to prevent the latter from tilting downwards by gravity.
[0005] However, the solution disclosed by the document has room for improvement, because the indexing of the lower wall on the housing creates stresses on the weld of the glass on the housing, which may hinder the sealing of the optical block. Description of the invention

[0012] According to one embodiment, at least one orifice on the extension comprising two oblong orifices, and at least one clipping member comprising two clipping members engaging in said two oblong orifices, respectively.
[0013] According to one embodiment, the at least one fastening element further comprises a flat tab coupled to the at least one clipping member, said tab comprising a width corresponding to at most 70% of a width of the at least one orifice.
[0014] According to one embodiment, the recess and the protrusion extend along a main horizontal direction or inclined at less than 10° to the horizontal.
[0015] According to one embodiment, the recess and the protrusion extend along a main direction curved in a horizontal plane or inclined at less than 10° with respect to a horizontal plane.
[0016] According to one embodiment, the recess and the protrusion are located at a junction between a side face and a front or rear face of the motor vehicle.
[0017] According to one embodiment, the support is located mainly under the housing and has a stepped profile supporting a lower edge of said housing.
[0018] According to one embodiment, the recess has a total surface area corresponding to at least 30% of a total surface area of the ice.
[0019] The measures of the invention are advantageous in that the fixing of the protrusion on the extension in the recess makes it possible to ensure rigid support of the bumper wall on the motor vehicle without risking affecting the sealing of the optical block or damaging it.
[0020] In addition, the invention makes it possible to guarantee good play and a flushness of the protrusion with the optical block, so as to respect increasingly demanding stylistic constraints.
[0021] Advantageously, the motor vehicle of the invention does not require the addition of any extra parts, thus offering a reduction in manufacturing costs. brication, and facilitating the assembly and disassembly operations of the bumper panel on the motor vehicle.

[0028] Fig. 1 represents a perspective view of a motor vehicle 2 comprising two optical blocks 4 and a bumper wall 6, said motor vehicle 2 being according to the invention.
[0029] The optical block 4 illustrated in [Fig.4] corresponds to a left rear light of the vehicle 2, the optical block 4 comprises a glass 4.1 fixed to a housing 4.1, the latter being fixed to the body of the motor vehicle 2 by means of a support which will be detailed in this description.
[0030] It can be seen that the optical block 4 has a recess 4.3 covered entirely by an extension 6.1 of the bumper wall 6. In this configuration, the recess 4.3 and the extension 6.1 are located at a junction between a side face 2.1 and a rear face 2.2 of the motor vehicle 2.
[0031] Alternatively, optical units corresponding to the front lights of the motor vehicle may have the recess 4.3 similarly to the rear light 4 shown in [Fig. 1]. Thus, the protrusion of a front bumper wall and said recess 4.3 will be located at a junction between the side face 2.1 and a front face of the motor vehicle 2.
[0032] Fig. 2 represents a perspective view of an internal face 6.2 of the protrusion 6.1 of the bumper wall 6.
[0033] The protrusion 6.1 comprises, on the right side of the inner face 6.2, a platform 8 comprising at least one fastening element 10, and preferably two fastening elements 10 comprising clipping members 10.1 intended to engage in corresponding holes presented at the level of the mounting support (not shown here) of the housing 4.2 on the body of the motor vehicle 2 of [Fig.1], so as to ensure a fastening of the protrusion 6.1 to the vehicle 2, such fastening will be detailed in this description.
[0034] The platform 8 is fixed to the inner face 6.2 by clipping or welding. Each fastening element 10 comprises a flat tab 10.2 extending projecting from the platform 8, said flat tab 10.2 is coupled to at least one clipping member 10.1.
[0035] Fig. 3 represents a perspective view of the optical block 4 with the mounting support 12 of said optical block 4 to the motor vehicle 2.
[0036] It can be seen that the recess 4.3 has a total surface area corresponding to at least 30% of a total surface area of the glass 4.1 of the optical block 4, said surface area being able to reach half of the surface area of the glass 4.1.
[0037] The mounting support 12 is located predominantly under the housing 4.2 and includes a stepped longitudinal profile so as to support a lower edge 4.4 of the housing 4.2.
[0038] Advantageously, the support 12 includes a lower part 12.2 extending vertically below the lower edge 4.4 of the housing 4.2 and includes openings 12.3 adapted to receive clips 6.3 of the wall 6 (illustrated in [Fig.2]) in order to ensure that said wall 6 is held on the support 12. The lower part 12.2 also includes two fixing holes 12.4 for screwing the support 12 onto the body of the motor vehicle.
[0039] The support 12 further includes an extension 12.1 extending into a projection of the recess 4.3. In this configuration, the extension 12.1 is positioned substantially at the right angle of the recess 4.3.
[0040] Preferably, the extension 12.1 extends vertically to the support 12 so that said extension 12.1 is substantially parallel to, and longitudinally close to, the protrusion of the bumper wall, and thus allow the latter to be fixed at the recess 4.3.
[0041] Fig. 4 represents a perspective view of the protrusion 6.1 of Fig. 2 mounted on the extension 12.1 of the support 12.
[0042] In this configuration, the two clipping members 10.1 of the fastening elements 10 of the platform 8 are engaged in the two corresponding oblong orifices 11.
[0043] Advantageously, mounting the protrusion 6.1 onto the support 12 is simple to perform. Indeed, the mounting can be carried out by an initial approach movement of the wall 6, illustrated by arrow A, towards the extension 12.1 at the level of the hollowing, up to the insertion of the fixing elements 10 into the orifices 11, followed by a second movement illustrated by the arrow B, allowing the protrusion 6.1 to be folded laterally in order to engage the clipping members 10.1 with the orifices.
[0044] Preferably, each tab 10.2 comprises a width, along a substantially horizontal direction, corresponding to at most 70% of a width of the oblong orifice 11. This allows to keep a lateral play wide enough to facilitate the assembly and disassembly operations of the bumper wall 6.
[0045] Fig. 5 represents a perspective view of a rear part of the optical block 4 and the support 12 illustrated in Fig. 3.
[0046] The optical unit 4 is shown in a normal mounting position on the motor vehicle (without the bumper panel). The housing 4.2 includes indexing pins 4.5 allowing the optical unit 4 to be indexed on the motor vehicle.
[0047] The recess 4.3, the extension 12, and the protrusion extend along a principal horizontal direction, corresponding to the XY plane, or inclined at less than 10° to said horizontal. Alternatively, the recess 4.3, the extension 12, and the protrusion may extend along a direction curved with respect to the horizontal.
[0048] Fig. 6 shows a cross-sectional view along axis AA passing through the optical block 4 and the support 12 of Fig. 5. Here, the protrusion 6.1 of the bumper wall 6 is shown in a mounting position in which each of the clipping means 10.1 is engaged in the corresponding oblong hole 11.
[0049] Preferably, the clipping means 10.1 is fixed on the tab 10.2, it comprises a V-shaped form made from an elastically deformable material.
[0050] Advantageously, the protrusion 6.1 is easily removable from the extension 12.1, so a replacement of the lamp of the optical block 4 is simple and quick, without risk of breaking the glass 4.1.
[0051] The present invention makes it possible to ensure that the protrusion is flush with the glass at the level of the recess without affecting the sealing of the optical unit or damaging it. To this end, increasingly demanding stylistic requirements of the motor vehicle can be met without the need for additional parts.
