Shock-absorber device, in particular for a micromechanical clockwork component

A shock-absorber and/or vibration-absorber device for cooperating with at least two micromechanical clockwork components, comprising:

• a shock-absorber assembly extending between a first end and a second end;
• said shock-absorber assembly comprising at least one flexible blade able to deform under the effect of a stress, said flexible blade being made of a material having a Young's Modulus greater than or equal to 50 GPa;
• and
• at least one dissipative layer made from a material having a shear modulus lower than the shear modulus of the flexible blade, a shock-absorbing factor greater than the shock-absorbing factor of said flexible blade, and at least partially secured to said flexible blade such that a flexion of the flexible blade, under the effect of a stress, provides shearing of the dissipative layer allowing dissipation of at least part of the energy from said stress;
• said first end of said at least a shock-absorber assembly being configured to cooperate with a first clockwork component;
• second end of said at least a shock-absorber assembly being configured to cooperate with a second clockwork component to absorb the shock when the first clockwork component moves relative to the second clockwork component,
• wherein said device comprises a plurality of shock-absorber assemblies extending from a central crown, each shock-absorber assembly comprising at least two curved flexible blades and at least one dissipative layer extending between said curved flexible blades.
