An articulation used in automobile seats, comprising: a mobile flange having a mobile flange inner toothing; a double satellite; a fixed flange having a fixed flange inner toothing for cooperating with said double satellite, the toothings of which mesh on one side with the fixed flange inner toothing of the fixed flange, and on another side with the mobile flange inner toothing of the mobile flange; an eccentric acting on the double satellite; a driving axis of the eccentric provided with at least one snug, the eccentric being made of two discs angularly mobile with respect to one another, each disc having an arched window; and a resilient element, said discs being connected to one another by said resilient element housed in said arched windows, while a central portion of each of said discs is formed with at least one circular recess, extended by a hollow housing adapted for receiving one of said snugs, and wherein each disc is noncircular and housed inside a bore of the double satellite; the two discs, when in a position spaced apart from one another, ensuring a clearance take-up and also an irreversibility of the articulation.
