  • the invention relates to the field of clock resonators, and especially those which comprise elastic blades acting as return means for the operation of the oscillator.
  • Shock resistance is a delicate point for most watch oscillators, and especially for cross-wound resonators. In fact, during out-of-plane shocks, the stress experienced by the blades quickly reaches very high values, which reduces the amount of travel the part can travel before yielding.
  • Shock absorbers for timepieces come in many variants. However, their main purpose is to protect the fragile pivots of the axis, and not the elastic elements, as conventionally the spiral spring.

  • the flexible elements consist of elastic blades crossed at a distance from each other in two parallel planes, the projections of the directions on one of the parallel planes intersect at the pivot axis virtual part of the mobile part.
