ABSTRACT OF THE DISCLOSURE In order to connect two adjacent elements (E1,E2) joined, for example, onto a satellite solar panel, an antifriction joint (10) is used, the deployment kinematics of said joint able to be known extremely accurately. This joint comprises two braces (12,14) suitable for rolling one onto the other by two cylindrical surfaces (12a,14a). Guiding of rolling is ensured by two flexible members, such as rolling plates (16,28) whose extremities are secured to the braces and which pass by crossing between the cylindrical surfaces (12a,14a). A traction prestressing stored in the plates avoids any stray movement between the braces, especially at the time of deployment. The drive torque ensuring the automatic deployment of the joint and its end-of-travel locking are ensured by elastic bands (36) connecting the two braces and each formed of two superimposed plates.
