A longitudinal member (LV) is installed parallel to a longitudinal side (CL) of a floor (PV) of a structure (SV) of a motor vehicle (VA), and comprises a profile (PL) having longitudinal internal walls and delimiting longitudinal internal boxes (C11-C32) and an inner edge (BI) participating in the delimitation of two first upper (C11) and lower (C12) internal boxes separated by a first intermediate internal box (C13) having a cross section in the general shape of a convex pentagon pointing initially towards an outer edge (BE) and capable, in the event of forces absorbed during an impact by the latter, to deform into a concave pentagon pointing towards the inner edge (BI) in order to allow a rotation of the profile (PL) about a longitudinal axis that causes a majority transfer of the forces towards the floor (PV).
