<p>Bumper structure 10 for a motor vehicle comprising at least two polymeric crash boxes 30 having preferably an alveolar structure, and comprising a cross member 20 which extends between the at least two polymeric crash boxes 30, in which the cross member 20 is a metallic cross member 20. The bumper structure 10 comprises connection means 40 which extend between the metallic cross member 20 and a frame of the motor vehicle, and besides which are positioned in proximity of the at least two polymeric crash boxes 30. The connection means 40 are plastically deformable and are unable to resist to compression stresses avoiding advantageously to transmit the compression stresses to the frame.</p> |
