| 摘要 |
<p>The invention relates to a structural part (13) capable of dissipating energy generated during an impact that compresses said part along an axis Z, comprising a web (131) having two opposite surfaces (133), characterized in that said part comprises: a through-window (134) extending between said opposite surfaces of the web, dividing said web into two main parts, referred to as a first part (135) and a second part (136), respectively, arranged in series along the axis Z; and a so-called energy-dissipation device comprising cutting means (112, 122) arranged within said window and capable of cutting at least one of said parts of the web into strips (139) by means of a compressive force exerted on said part along the Z axis, and means (113, 123) for clearing away the thus-formed strips.</p> |
