Abstract

La présente invention concerne un siège de véhicule comprenant un dossier (2), une assise (3) et un système de ceinture de sécurité à quatre points (4; 4') qui comprend deux ceintures d'épaule (5, 6) qui présentent respectivement à leur extrémité supérieure un point de fixation supérieur (8, 9) dans la zone du dossier (2) et qui présentent respectivement à leur extrémité inférieure dans la zone de l'assise (3) du siège de véhicule (1; 1'), un point de fixation inférieur (10, 11). Pour permettre, lors de l'utilisation d'un système de ceinture de sécurité à quatre points (4; 4'), d'éviter un glissement du bassin du passager du véhicule lors d'un accident, le système de ceinture de sécurité à quatre points (4; 4') est selon l'invention doté d'une ceinture de bassin (7; 7') qui relie les deux ceintures d'épaule (5, 6) entre elles par l'intermédiaire de dispositifs de renvoi (12, 13) correspondants dans la zone des points de fixation inférieurs (10, 11).
