Abstract: An articulation for an automobile seat includes a mobile flange having an inner toothing, a fixed flange having an inner toothing for cooperating directly with the mobile flange and an eccentric means positioned between the mobile flange and the fixed flange for biasing aa articulating element. The eccentric means including a driving axis provided with a snug and a pair of discs rotatable about the axis relative to one another. Each disc having a central recess and an arc-shaped window. The central recess having a hollow housing extending outwardly for receiving the snug of the axis. A resilient member is positioned within the arc-shaped windows of the discs and bears against bearing surfaces provided at the ends of the windows. When the two discs are spaced apart from one another by the eccentric means, the articulation ensures the clearance take-up and the irreversibility of the articulation.
