Abstract

L'invention concerne une carrosserie de véhicule comportant un montant de carrosserie (3), en particulier un montant milieu, qui présente un support modulaire (14) qui porte des éléments fonctionnels (20, 21, 23, 24) d'un système de ceinture de sécurité (19) et/ou un habillage de montant (17). Selon l'invention, le support modulaire (9) fait partie intégrante d'une unité de prémontage (VM) séparée de la carrosserie de véhicule (50), unité de prémontage sur laquelle les éléments fonctionnels (20, 21, 23, 24) et/ou un habillage de montant (17) sont prémontés. Le support modulaire (9) est assemblé en au moins un point d'attache (S), côté montant, du montant de carrosserie (3), dans une étape de processus d'assemblage (ZSB). Afin de simplifier l'étape de processus d'assemblage (ZSB), le support modulaire (9) et le montant de carrosserie (3) présentent un auxiliaire de positionnement (P) au moyen duquel le support modulaire (9) peut être prépositionné en position correcte dans une position de liaison, en particulier une position de vissage (SP), dans laquelle le support modulaire (9) peut être assemblé au montant de carrosserie (3).
