Abstract (en)

[origin: US2019324401A1] A timepiece resonator mechanism including a structure carrying, via a flexible suspension system, an anchor unit to which is suspended an inertia element oscillating with a first rotational degree of freedom RZ, under the action of return forces exerted by a flexure pivot including first elastic strips each fixed to the inertia element and to the anchor unit, the flexible suspension system being arranged to allow the anchor unit some mobility in every degree of freedom except the first rotational degree of freedom RZ wherein only the inertia element can move to avoid any disturbance to its oscillation, and the stiffness of the suspension system in the first rotational degree of freedom RZ is very considerably higher than the stiffness of the flexure pivot in this same rotational degree of freedom RZ.
