A polymeric crash box (10) for a motor vehicle having a first open frontal extremity (12) and a second rear extremity (14), further including a substantially alveolar structure (20) having a plurality of channels (30) realized in just one piece which extends internally to the polymeric crash box (10), each channel (30) further being internally tapered towards the second rear extremity (14). The polymeric crash box (10) includes at least a substantially planar polymeric fixing element (52) which is realized in a single piece in proximity of the first frontal open extremity (12) and which further can be fixed to a crossbeam (60). A bumper structure for a vehicle including at least two polymeric crash boxes (10) and having a substantiallyΩ-shaped cross-section, and an external polymeric bumper housing covering the crossbeam (60) and the two at least polymeric crash boxes (10). |
