Note that the attachment of the rear part of the projector 2 on the hinge support 4 is not blocked in the X direction so as to meet the regulations on pedestrian impacts (the elements must go unhindered in the direction X when an effort exceeds an effort predetermined threshold). Similarly, for the same reasons related to pedestrian impacts, the fasteners of the projector 2 on the support 9, on the bridge 14 and on the lower part of the technical front face 1 are shaped to break in the longitudinal direction X when an applied force exceeds a predetermined threshold force.
