Abstract

See full text

A horological resonator mechanism, including a structure and an anchoring unit from which is suspended at least one inertial element arranged to oscillate along a first degree of freedom in rotation RZ about a pivoting axis extending along a first direction Z, the inertial element being subjected to return forces exerted by a virtual pivot including a plurality of substantially longitudinal elastic strips, each fastened, at a first end to the anchoring unit, and at a second end to the inertial element. Each elastic strip is deformable essentially in a plane XY perpendicular to the first direction Z. The anchoring unit is suspended from the structure by a flexible suspension arranged to allow the mobility of the anchoring unit along a plurality of degrees of freedom including at least two in the plane XY, along a direction X and along a direction Y orthogonal to the direction X.
