Transverse beam of a frontal module of a vehicle, frontal module and radiator support comprising such a transverse beam

The crossbeam has an inertia part (12) and a geometrical stabilization part (14) longitudinally divided into two parts (14a, 14b) at a side and opposite side of a hood, respectively. The parts (14a, 14b) are projected from the stabilization part such that force equivalent to collision of a pedestrian with the hood is transmitted towards a part (14b) by deforming the inertia part and the part (14a). An independent claim is also included for a support of a cooling module of a motor vehicle.
