Swivelling cable fastener and dynamic cable guiding method

A cable fastener (2) for fastening at least one cable (6) to a structure (1), part of which is movable between an initial position and an end position, the cable fastener (2) comprising:

• a base plate (4) defining a reference plane (H) and integral with the structure (1);
• a cable clamp (3), the clamp (2) being inserted in the base plate (4);
• a return device arranged between the cable clamp (3) and the base plate (4), each of which has an anchoring mechanism (5a, 5b) connected to the return device, the latter holding the cable clamp (3) in a nominal position when the movable part of the structure (1) is in the initial position;
• the cable clamp (3) pivoting about a pivot axis (P) in the base plate from the nominal position when at least one of the cables is stressed in a direction (D) by the movement of the movable part of the structure (1) and pivoting back to the nominal position under the effect of the return device when the cables are released, and the return device being a torsion spring (5) along an axis coincident with the pivot axis (P) of the cable clamp (3) and comprises a body (5c) as well as two ends (5d, 5e) extending tangentially with respect to the body (5c),
• wherein the base plate (4) has a hollow cylinder (4c) around which the torsion spring (5) is arranged and into which the cable support (3a) of the cable clamp (3) is inserted.
