Title (EN) ENERGY ABSORBING STRUCTURE
(FR) STRUCTURE D'ABSORPTION D'ENERGIE
Abstract:
(EN) An energy absorbing structure (1) suitable for example for use in a motor vehicle body panel to absorb impact loads comprises a wall (3) having a plurality of ridges (2) extending in a longitudinal direction corresponding to the expected direction of an applied load, and at least one reinforcement (6) secured to the wall on adjacent ridges. The dimensions of the ridges and the points (7) at which the reinforcement is secured are so arranged that the wall undergoes progressive collapse under impact in the longitudinal direction (A).
(FR) Structure d'absorption d'energie (1) appropriee par exemple a une utilisation dans une tole de carrosserie d'un vehicule automobile pour absorber les charges d'impact, comprenant une paroi (3) ayant une pluralite d'aretes (2) s'etendant dans un sens longitudinal correspondant au sens presume d'une charge appliquee, et au moins un renforcement (6) fixe sur la paroi sur les aretes adjacentes. Les dimensions des aretes et les points (7) au niveau desquels le renforcement est fixe sont disposes de telle sorte que la paroi soit soumise a un enfoncement progressif sous le choc dans le sens longitudinal.
