Abstract
To enable the inclination of the metal framework of a seat-back of a vehicle seat to be adjusted with respect to the metal framework of the seat-bottom of this seat, elements of these two frameworks are constituted in the form of curvilinear sectional bars (6, 7) nestable contiguously in one another and centered on the same transverse horizontal axis positioned close to the pivoting axis of the hips of a person sitting on the seat and an adjusting and locking mechanism (13, 14) is provided enabling the degree of mutual fitting into one another of these sectional bars to be adjusted as desired.
