On at least one surface of a structural part, on all or part of a hollow section between outer and inner peripheral borders, is associated at least one cover sheet made of rigid metallic material. The at least one cover sheet is mechanically fixed with the edge of the peripheral borders of the structural part, and covers all or part of inner cavities formed on open sides of the part. The at least one cover sheet has a triple function: to increase the rigidity of the structural part, to absorb shock by deforming in a plane while remaining integral with the part, and to allow reduction of the mass of the structural part and optimization of the mass/performance ratio.
