Abstract

L'invention concerne une unité de verrouillage (10) destinée à un siège de véhicule (1), comprenant une poignée de déverrouillage (82) qui est reliée à un cliquet (30) au moyen d'une tige d'actionnement (57). Selon l'invention, une attache de montage (92) qui est élastiquement déformable, peut passer d'une position initiale dans laquelle l'attache de montage (92) empêche le mouvement de la tige d'actionnement (57) en direction axiale, à une position de montage dans laquelle le mouvement de la tige d'actionnement (57) en direction axiale est possible.
