Claim 13:
14. A bumper reinforcement that is produced by molding a thermoplastic material and intended to be integrated into a front assembly for a motor vehicle between a bumper and a technical part, characterized in that the bumper reinforcement comprises at least one mounting plate for supporting at least one sensor, is integral with said bumper reinforcement, and is linked by its perimeter to said bumper reinforcement by means of a fragile material bridge,
wherein the material bridge is formed by an alternation of at least one first zone (Z1), in which the material bridge has a thickness (e1) that is less than or equal to the thickness (ep) of a wall of the mounting plate and greater than or equal to an intermediate thickness (ei) that is strictly less than the thickness (ep) of the wall of said mounting plate (ei≤e1≤ep), and at least one second zone (Z2) in which the material bridge has a thickness (e2) that is less than or equal to the intermediate thickness (ei) and greater than or equal to zero thickness (0≤e2≤ei),
wherein the material bridge comprises at least one first hinge zone (Z1c) in which a thickness of the material bridge is equal to a thickness (ep) of the wall of the mounting plate.
