Abstract

Un dispositif d’absorption d’énergie (30) pour une colonne de direction (10) comporte une tôle (42) comportant une zone d’interférence (50) traversée par une lumière d’interférence (74) s’étendant parallèlement à une direction longitudinale (200) du dispositif d’absorption (30), et un curseur de déformation (84) apte à provoquer une déformation plastique de la tôle (42) par interférence de forme avec les parois de la lumière d’interférence (74) lors d’un mouvement relatif de translation parallèlement à la direction longitudinale (200). La tôle (42) comporte deux zones latérales (52) situées de part et d’autre de zone d’interférence (50) et reliées à la zone d’interférence (50) chacune par une zone de raccordement (56) plastiquement déformable comportant au moins deux plis (58). (Figure de l’abrégé : Fig. 2)An energy absorbing device (30) for a steering column (10) comprises a sheet metal (42) comprising an interference zone (50) traversed by an interference lumen (74) extending parallel to a longitudinal direction (200) of the absorbing device (30), and a deformation slider (84) capable of causing plastic deformation of the sheet metal (42) by shape interference with the walls of the interference lumen (74) during a relative translational movement parallel to the longitudinal direction (200). The sheet metal (42) comprises two lateral zones (52) located on either side of the interference zone (50) and connected to the interference zone (50) each by a plastically deformable connection zone (56) comprising at least two folds (58).
