Abstract

A vehicle seat in which the backrest is controlled in terms of rotation about an axis of pivoting by an adjustment mechanism which includes an input shaft, a fixed flange integral with the framework of the seat cushion, and a mobile flange which can rotate about an axis parallel to the axis of pivoting of the backrest but offset therefrom. The mobile flange is integral with a pin which penetrates an oblong slot in the framework of the backrest so as to be able to rotate inside this slot and so as to be able to slide radially with respect to the axis of pivoting of the backrest. This pin is further from the axis of pivoting of the backrest than from the axis of rotation of the mobile flange, so that the adjustment mechanism can withstand low torques.
