<p>This relates to a tensor device for a cable kinematic chain, for example a window-winder for an automobile vehicle, made up of a triangular grooved cylindrical body (2), perpendicular to its shaft, which is mounted on one of the drive outlets, and receives a toothed open ring (3) in the opposite direction to the above, made of flexible thermoplastic material, which clamps onto the cylinder. Mounted inside the casing is a spring (4) which acts on the grooved cylindrical body. The relative movements of the ring and the cylindrical body on the casing, and of the cylinder on the ring and the casing provide the system with its double tensing capacity, which differentiates permanent stretching from temporary elongations caused by an overload on the system. <IMAGE></p> |
