Abstract
A shock absorber spring (1) for a timepiece (200), extending substantially in a plane (P1) and having a first axis of symmetry (A1) perpendicular to the plane (P1), the spring including at least two first spring-fixing elements (11, 11′, 11″), these first fixing elements each comprising at least a first fixing surface (11a, 11b, 11a′, 11b′, 11a″, 11b″) oriented at least substantially radially relative to the first axis (A1) and towards the first axis (A1).
Claims20
A shock absorber spring for a timepiece, extending substantially in a plane and comprising a first axis of symmetry perpendicular to the plane, the spring comprising:
- at least two first spring-fixing elements,
- wherein each of the first fixing elements comprises at least one first fixing surface oriented at least substantially radially relative to the first axis and towards the first axis, wherein the at least one first fixing surface is on a lobe projecting toward the first axis relative to respective adjacent surfaces also oriented at least substantially radially relative to the first axis and towards the first axis, the adjacent surfaces being respectively located on either side of the at least one first fixing surface along an orthoradial direction relative to the first axis.
A bearing body having a second axis of symmetry, the bearing body comprising:
- at least two second spring-fixing elements for fixing a spring,
- wherein each of the second spring-fixing elements comprises at least one second fixing surface oriented at least substantially radially relative to the second axis and in a direction away from the second axis,
- wherein each of the second fixing elements comprises a stud, the second fixing surfaces being created on the studs.
