Abstract (en)
[origin: US2019032644A1] Mechanical horological movement comprising at least one energy storage means designed to drive a gear train of which an output mobile component is designed to pivot about a drive axis and comprising a rotary resonator which comprises at least one central mobile component designed to pivot about a central axis and comprising an input mobile component designed to collaborate with the output mobile component, this rotary resonator comprises a plurality of inertial elements each one designed to pivot with respect to the central mobile component about a secondary axis perpendicular to the central axis and each returned towards a rest position, relative with respect to the central mobile component, by at least one elastic return element, and each secondary axis passes through the centre of mass of the inertial element associated with it.
