摘要

The adjusting mechanism for the backrest of the vehicle comprises a base (2) joined to the seat part and a base (3) attached to the lower area of the backrest, both rotating around a central axis (33). A hub (15) attached to the drive shaft (18) is divided by gaps into several axially positioned elements with hook-shaped front ends (20) engaging with the complementary base (3). Each of the elements is separated by a concentric slot (24) in an inner (26) and an outer segment (25) being slightly spread apart during assembly.
