    Abstract: A cross member (1) for a bumper beam includes an outer beam (2) with a main beam portion (3) comprising an upper beam wall (12), a lower beam wall (14) and a front beam wall (16), defining together a beam inner volume (17) open in a back direction, a reinforcement element (4) defining a reinforced area (24) of the outer beam (2), located inside a part of said beam inner volume (17) and having a cross section, defining a reinforcement inner volume (25) open in the rear direction, a closing plate (6) closing at least a part of the beam inner volume (17). The cross section of the reinforcement element (4) has a shape which is not matching the shape of the outer beam (2) in the reinforced area (24).

    Abstract: A cross member for a bumper beam includes an outer beam, an inner reinforcement element extending inside at least a part of the outer beam inner volume and comprising at least two reinforcement ribs protruding towards the front beam wall, the reinforcement ribs being connected together at least at their back end, opposite to the front beam wall, by an upper transversal branch and a lower transversal branch, the upper and lower transversal branches being attached respectively to the upper and lower beam flanges of the outer beam, wherein each reinforcement rib abuts the front beam wall and the length of the upper transversal branch is less than the length of the upper beam wall and the length of the lower transversal branch is less than the length of the lower beam wall, the lengths being measured in the longitudinal direction.
