Abstract

Dispositif d'absorption du choc. Il comprend un corps polyédrique creux pourvu d'une pluralité de fentes découpées dans chacune de ses parois latérales, ces fentes étant parallèles les unes aux autres dans une direction perpendiculaire à l'axe longitudinal du corps, chaque fente ayant l'un de ses bords longitudinaux en saillie vers l'extérieur par rapport à l'autre bord longitudinal, de façon à absorber l'énergie de choc par déformation ou rupture partielle. Application aux automobiles ou camions.
