Abstract (en)
[origin: EP2434353A1] The anti-tripping hairspring (1) has a blocking unit for blocking multiple turns (13), when rotation amplitude of the hairspring from balancing position to an extreme position attains determined angle. The unit has transversal segments (15) integrated to the turns, where the transversal segments are radial. The transversal segments are extended beyond two portions of a spiral (14), where the hairspring is made of silicon and metal. An independent claim is also included for a detect escapement of a timepiece comprising a tilting unit.
