According to the method, to manufacture a rear frame side member for a vehicle, firstly a plate is formed by welding a front plate and a rear plate (31, 33) to each other, which are made of different steels so that the rear sheet (33) defines a rear segment of the side member (11) with greater deformability under strain with low directed longitudinally; a further sheet (32) is welded onto the front sheet (31) of the plate so as to form a flat blank (34), which is then hot pressed, so as to define a U-shaped cross section, and cooled so as to harden the steel of the front sheet (31).
