Abstract:
1. A device for tensioning a belt, the device comprising: a supporting base; a belt winding reel, the winding reel being able to rotate relative to the base about an axis of rotation a ring gear rotating integrally with the reel, an operating lever for rotating the reel in a first predetermined direction of rotation for winding the belt; and a ratchet gear assembly operating on the ring gear, the ratchet gear assembly including a first tooth mounted to a support arm for engagement with the ring gear, the first tooth pivoting relative to the support arm about a first axis of oscillation and the support arm pivoting about a second axis of oscillation, the first tooth being designed to oscillate about the first and second axes of oscillation in order to prevent reel rotation in a second direction of rotation opposite to the first predetermined direction; and a respective release mechanism which disengages the first tooth from the ring gear in order to allow belt unwinding by reel rotation in the second direction of rotation.
