An energy absorber (10) comprising a base (12) and a plurality of recesses (16) extending from the base (12). At least some of the plurality of recesses (16) have a rim (22), a first wall (17) extending between the base (12) and the rim (22), a first floor (44), and a second wall (42) extending between the rim (22) and the first floor (44). At least some of the plurality of recesses (16) are oriented such that their first and second walls (17, 42) are inclined respectively at angles alpha and beta to a major incident component (24) of the impacting force, where alpha and beta lie between 1 and 45 degrees.
L'invention concerne un absorbeur d'énergie (10) comprenant une base (12) et une pluralité de renfoncements (16) s'étendant à partir de la base (12). Au moins certains des renfoncements (16) présentent une couronne (22), une première paroi (17) s'étendant entre la base (12) et la couronne (22), un première fond (44), une seconde paroi (42) s'étendant entre la couronne (22) et le premier fond (44). Au moins certains des renfoncements (16) sont orientés de sorte que leur première paroi (17) et que leur seconde paroi (42) sont inclinées, respectivement selon un angle alpha et selon un angle bêta, vers un composant incident principal (24) de la force d'impact, alpha et bêta étant compris entre 1 et 45 degrés.
