Abstract

L'invention concerne un siège de véhicule (101) comprenant une partie siège (120) qui peut passer d'une position d'utilisation à une position de non-utilisation, un dossier de siège (110), une base (140), et une cinématique de siège (K) reliant la partie siège (120) par pivotement à la base (140), la cinématique de siège (K) ayant une bascule (160) qui, au moyen d'un premier joint rotatif (I), est déviée par pivotement sur un adaptateur (151 ; 151A, 151B) relié à la base (140) et qui, au moyen d'un second joint rotatif (II) est déviée par pivotement sur la partie siège (120). Un espacement (A) entre la base (140) et la partie siège (120) peut être modifiée en sélectionnant un premier point d'articulation (191A, 191B) pour l'articulation du premier joint de pivot (I) sur l'adaptateur (151A, 151A, 151B) reliée à demeure à la base (140) et/ou en sélectionnant un second point d'articulation (192A, 192B) pour l'articulation du second joint de pivot (II) sur la partie siège (120). L'invention concerne également un procédé d'assemblage d'un tel siège de véhicule (101).
