Abstract

Le procédé consiste à: a) détecter une collision moyennant un système de capteurs; b) en cas de collision frontale ou de capotage, b1) diminuer la hauteur par rapport à l'extrémité de la partie du siège la plus proche à la partie dossier par rapport à l'extrémité opposée de la partie de siège; b2) faire tourner la partie de dossier par rapport à la partie de siège pour en rapprocher les parties; c) en cas de collision arrière; c1) faire que la partie dossier augmente l'angle formé avec la partie siège de manière que les deux parties soient alignées; c2) faire que tout le siège décrive un mouvement général vers l'arrière.
