Abstract (en)
[origin: EP2746865A1] The barrel (1) has a spring (7) accommodated between a drum (6) and a cover (8) and attached between the drum at its outer end and a shaft (3) at its inner end. The shaft is secured to pivot with a ratchet (2) around a pivot axis. A single-piece subset (10) is coaxial to the shaft and regroups the ratchet or/and the shaft around a core (4). The single-piece subset is pivoted at upper bearing surface (13) in a hole (51) of the bridge or of a stone (52) comprising the bridge. The stone includes an upper shoulder (11) whose race is limited by a lower surface of the bridge or stone.
