Abstract

Le problème décrit par la présente invention est de supprimer un déplacement d'un coussin par rapport à un cadre de dossier de siège dans un siège de véhicule. La solution selon l'invention porte sur un siège de véhicule 3 qui inclut un cadre de dossier de siège 11, un coussin 16 et un dispositif de verrouillage 34 qui est disposé sur le cadre de dossier de siège et qui vient en prise de façon détachable avec une saillie de mise en prise 33 disposée sur la carrosserie de véhicule ou un siège adjacent 2. Le cadre de dossier de siège comporte des éléments latéraux gauche et droit 21 qui s'étendent verticalement pour former des parties latérales gauche et droite du dossier de siège.
