• the French patent application FR 2985472 discloses a front projector for a motor vehicle whose lower part of the housing is provided with a lower anchoring element intended to cooperate with a tab rigidly connected to said body structure of this vehicle.
• This lower anchoring element comprises two vertical parallel flanges integrally formed with the housing, each comprising a receiving slot extending longitudinally from their rear end.
• the tab slides simultaneously along the two slots to reach the bottom portion of the latter whose width corresponds to the thickness of this leg , so as to vertically lock the projector vis-à-vis the body structure of the vehicle.
• This lower anchoring element plays also ensures a premaintenance of the projector facilitating the screwing of the upper anchoring elements on the body structure.
• the present invention is therefore aimed at ensuring a more effective pre-hold as well as obtaining improved touches of touch between the projector glass and the adjacent elements of the vehicle.

• said lower anchoring element comprises a vertical connecting wall transversely connecting said flanges and said slits extending longitudinally from their rear end and to near said connecting wall;
• said flanges extend at the front of said connecting wall by a respective reinforcing rib extending to the peripheral edge of said housing supporting said cover glass;
• At least one of said reinforcing ribs has a frangible zone constituted by a weakening groove extending longitudinally in the extension of the corresponding receiving slot;
• said connecting wall has a notch extending vertically from its lower end to a height slightly greater than that of said receiving slots, said elastically deformable tongue taking root at the upper end of said notch and extending rearwardly between said flanges by tilting down;

• the terms “front”, “rear”, “lower”, “upper”, “longitudinal” and “transverse” will be defined with respect to the mounting position of this projector 10 on the vehicle.
• the projector 10 comprises a housing 11 enclosing at least one light source 12 and whose peripheral edge supports a transparent cover glass 13.
• the housing 11 includes anchoring elements for mounting the projector 10 on the body structure of the vehicle.
• this housing 11 comprises two upper anchoring elements 14 disposed at its two upper lateral ends, and a lower anchoring element 15 disposed in its lower part near its outer lateral end.
• This lower anchoring element 15 is provided to cooperate, when mounting the projector 10 on the body structure, with a rigid flat metal lug 3 rigidly connected to the body structure.
• this lug 3 constitutes the front end of a metal tongue 2 provided with an arcuate longitudinal rib 2A for reinforcing its rigidity.
• the lower anchoring element 15 is integral with the rest of the housing 11 by molding from a suitable thermoplastic polymer such as acrylonitrile butadiene styrene (ABS).

• the two flanges 16, 17 extend forward of the connecting wall 20 by a respective reinforcing rib 22, 23 extending to the peripheral edge 11A of the housing 11 supporting the transparent cover ice 13.
• reinforcement rib 23 of the outer flange 17 is thus much shorter than that 22 of the inner flange 16 ( Figure 6).
• This reinforcing rib 22 has a frangible zone consisting of a weakening groove 22A extending longitudinally on the inner side over its entire length in the extension of the receiving slot 18 ( Figures 1 and 6).
• the connecting wall 20 has a substantially rectangular notch 24 which extends vertically from its lower end to a height slightly greater than that of the two receiving slots 18, 19.
• An elastically deformable tongue 25 takes root at the upper end of this indentation 24 and extends rearwardly between the two flanges 16, 17 by tilting slightly downwards.
• This tongue 25 has at its free end, a ratchet tooth 26 located at the same height as the two receiving slots 18, 19 and intended to cooperate with a rectangular window 4 formed in the metal tab 3 rigidly connected to the structure of vehicle body ( Figures 2 and 3).

• This collapsing movement of the projector 10 has the collateral effect of automatically placing the lower anchoring element 15 opposite the corresponding rigid flat tab 3.
• This projector 10 is also locked vertically due to the correspondence between the width of the slots 18, 19 and the thickness of the tab 3.
• this lower anchoring element 15 has clipped correctly on the leg 3 (a sound confirmation of the smooth running of this operation being provided to the operator thanks to the noise emitted by the tongue when it returns to its position. initial position), the projector 10 is permanently pre-maintained in its mounting position on the body structure. The operator can then serenely make the fastening by screwing the upper anchoring elements 14 on corresponding tabs rigidly connected to the body structure.
• the lower anchoring element 15 also contributes to improving the passive safety of the vehicle in the event of a frontal impact, in particular with the legs of a pedestrian.
• the headlamp 10 is urged violently towards the rear and the force exerted by the rigid metal lug 3 on the two flanges 16, 17 causes them to break in the extension of the receiving slots 18, 19 (the rupture of the flange 17 with the reinforcement rib 23 of larger dimension being facilitated by the presence of the weakening groove 25.
• This rupture of the flanges 16, 17 thus allows the projector 10 to sink inside the body structure by absorbing a portion of the energy dissipated during the shock, which reduces the trauma suffered by the legs of the pedestrian.
