An energy absorbing assembly (10) is provided for decelerating an object that impacts the assembly. The assembly comprises an incident member (12) having an incident surface (14) that meets the impacting object and at least one energy absorbing member (16) attached to an attachment region (17) of an opposing face (18) of the incident member (12) for accommodating deformation of the assembly (10). The energy absorbing member (16) comprises a lattice of interconnected strands (20), wherein the strands (20) intersect to define a plurality of cells (22). The energy absorbing member (16) is oriented such that the plane of each cell (22) is substantially perpendicular to the attachment region (17) in order to maximize energy absorption over a given distance. The lattice collapses and at least some of the cells (22) become at least partially closed during energy absorption.
L'invention concerne un ensemble absorbant l'énergie (10), conçu pour ralentir un objet venant heurter l'ensemble. Ledit ensemble se compose d'un élément d'incidence (12) ayant une surface d'incidence (14) avec laquelle l'objet percutant vient en contact et au moins un élément absorbant l'énergie (16) fixé à une zone de fixation (17) d'une face opposée (18) de l'élément d'incidence (12), et destiné à s'adapter à la déformation de l'ensemble (10). L'élément absorbant l'énergie (16) présente un treillis de fils (20) reliés entre eux et se croisant pour définir plusieurs cellules (22). L'élément absorbant l'énergie (16) est orienté de sorte que le plan de chaque cellule (22) est sensiblement perpendiculaire à la zone de fixation (17), et que l'absorption d'énergie soit maximisée sur une distance donnée. Le treillis s'affaisse et au moins certaines des cellules (22) restent au moins partiellement fermées pendant l'absorption d'énergie.
