Front unit assembly of an automotive vehicle, comprising an improved components-fastening device, and vehicle equipped with such an assembly

Front unit assembly of an automotive vehicle, comprising a front face (7) having a central section (9) and two lateral sections (11), a bumper (17), a bumper skin (19) forming the fillet of said bumper, two brackets (43), each extending from the central section (9) to which it is fixed towards a respective lateral section (11) and forming support members for said bumper skin (19), and two optical units (21), each being supported by a respective lateral section (11) and having a lateral peripheral section suitable for cooperating with a complementary recess (25) in a respective front wing section (5), wherein each optical unit (21) and the respective front wing section (5) are fixed rigidly to the corresponding bracket (43) at a same reference point of attachment (60), said bracket (43) being endowed with an elasticity substantially greater than that of the front face (7), so that it is prone to elastic deformation as a function of relative adjustment movements of the bumper skin (19), the wing (5) and/or the optical unit (21).
