Abstract

L'invention concerne une automobile comportant un élément de renvoi supérieur d'un système de ceinture de sécurité, maintenue sur un élément composé d'un revêtement intérieur et d'un revêtement extérieur, en particulier la colonne B ou la colonne C de l'automobile. L'élément de renvoi est fixé sur l'élément muni d'un revêtement de colonne, à l'aide d'un système de jonction transmettant la charge. L'invention vise à diminuer la sollicitation dont la personne munie de la ceinture fait l'objet en cas de choc latéral. A cet effet, il est prévu que l'élément de renvoi soit fixé sur une tôle support (22)introduite dans l'élément (10) et montée déplaçable par rapport audit élément (10) par l'intermédiaire de l'espace creux formant une section d'amortissement entre le revêtement intérieur (12) et le revêtement extérieur (11) de l'élément (10). Le revêtement de la colonne (14) présente quant à lui une structure lui permettant de suivre le mouvement de déplacement de l'élément de renvoi.
