1. An articulation mechanism comprising:
first and second frames mounted in a rotatable manner with respect to one another and connected together by a gear that has:
a first circular toothing directed outwards, centered on a first axis and integral with the first frame,a second circular toothing directed inwards, centered on a second axis parallel to the first axis and offset in relation to said first axis, said second toothing presenting an inner diameter greater than the outer diameter of the first toothing, the first frame having a cylindrical housing of revolution centered on the first axis, a control device with an eccentric cam and radial play adjustment, mounted in a rotatable manner around the second axis in the cylindrical housing of the first frame, said articulation mechanism having a rigid load-spreading washer disposed radially in relation to the second axis, which is mounted in a rotatable manner on the second frame around the second axis and which is disposed in the cylindrical housing of the first frame with play, the outer periphery of the load-spreading washer being circular and centered on the first axis, and the load-spreading washer being rotated by the control device. |
