Abstract
The invention relates to an articulation joint which can move in a controlled manner between two elements that can rotate in relation to one another about an axis .DELTA., comprising: a hub (6) which is equipped with a cylindrical bore (7) having a .DELTA. axis and which is intended to be fixed to the first element; and a shaft (10) which is engaged in the bore in the hub (6), such that it can move in relation to the hub in rotation about axis .DELTA., and which is intended to be fixed to the second element. The invention is characterised in that the hub (6) and the shaft (10) are elastic and can deform under a stress (F3, F4) which is perpendicular to the .DELTA. axis and which is greater than a given value, in order to lock or brake the .DELTA. axis rotation.
