Abstract (en)
[origin: EP2570863A1] The assembly (1) has a driving spring (2) mounted between a drum (3) and a reception surface (5) of a core (4). Maximum radius of the core with respect to a pivoting axis (D) is less than ten times the maximum thickness of the spring. An arbor (18) comprises a ratchet holder (81) placed between an end shoulder (85) and a bearing (84), and provided with another bearing to drive a ratchet (12). The ratchet holder directly or indirectly limits the play of the drum relative to a bearing surface of the core that borders the reception surface. An independent claim is also included for a movement.
