Abstract

L'invention concerne un système pantographique qui comprend une carcasse, un siège de véhicule, une paire de supports de fixation, au moins une structure de pliage, un arbre de base, deux arbres diagonaux, deux supports de couplage, deux raccords, deux moyens de fixation et une région de raccordement. La présente invention vise à fournir une structure de pliage destinée à être couplée à la structure d'un siège de véhicule d'une automobile, permettant une nouvelle solution lorsqu'il s'agit de déplacer un siège de véhicule d'une position verticale à une position horizontale, lorsque le siège de véhicule est déjà couplé au véhicule dans lequel le siège de véhicule sera installé, afin d'obtenir une meilleure facilité d'utilisation, ce qui se traduirait par un meilleur confort, ainsi qu'un meilleur ajustement.
