Abstract

Pour améliorer le pivotement et le rendement d'un barillet, l'invention concerne un ressort de barillet de mouvement de montre, caractérisé en ce qu'il comporte une pluralité de lames (10a, 10b) coplanaires enroulées en spirale l'une dans l'autre,
en ce que les extrémités intérieures de chaque lame sont chacune solidaires d'un dispositif d'attache (12), pour être fixé sur un arbre de barillet,
en ce que les extrémités extérieures de chaque lame sont disposées sensiblement symétriquement par rapport au centre de la spirale et sont
agencées de manière à pouvoir coopérer avec un tambour de barillet.
L'invention concerne également un barillet contenant un tel ressort.
