    Abstract: A bumper-reinforcing system (1) intended for a motor vehicle includes: a bumper beam (2) with a single-piece elongated profile with a closed cross section and including a center zone (21) extending at least over part of the entire width of the bumper beam and an end zone (22) at each extremity of the bumper beam, two bumper fasteners (3) connected to the rear side of the bumper beam (2) at the intersection between the center zone (21) and the end zone (22) of the bumper beam (2), two reinforcing tubes (4) connected by their first end to the rear side of the end zone (22) of the bumper beam (2), extending from the bumper beam (2) so as to form an angle α below 45° with the vertical plane of symmetry of the bumper beam and suited to be connected by their other end on the front rail of the vehicle for which the bumper-reinforcing system (1) is provided, and two covers (5) with a single-piece elongated profile with an open cross section, in contact with the rear side of the end zone (22) of the bumper beam (2) and extending at least from the first end of one of the reinforcing tubes (4) to one of the bumper fasteners (3).

    Abstract: The vehicle underbody structure (20) includes a floor panel (24) and an underbody reinforcement element (26), the underbody reinforcement element (26) including at least a front transversal beam (112a, 112b) and a rear transversal beam (114), the transversal beams (112a, 112b, 114) extending parallel to each other and being attached to the floor panel (24). The front transversal beam (112a, 112b) and the rear transversal beam (114) are made of a press hardening steel having a tensile strength higher than or equal to 1300 MPa.

    Abstract: A vehicle front body structure containing an upper longitudinal beam and a upper fender rail for supporting a fender of the vehicle, said upper fender rail extending in a longitudinal direction substantially parallel to the upper longitudinal beam and having a front end and a rear end spaced apart along the longitudinal direction.
    The resistance to plastic deformation of the upper fender rail increases from the front end of the upper fender rail to the rear end of the upper fender rail. The yield strength of the material of the rear section is greater than the yield strength of the material of the front section and/or the rear section has a greater wall thickness than the wall thickness of the front section.
