Abstract
A timepiece mechanism comprising a regulator, an energy distributing member a pallet fork controlled by the regulator to alternate in locking and releasing the energy distributing member, and a decoupling member elastically connected to the pallet fork and to the regulator. The decoupling member is arranged so as to oscillate between two stop elements.

A mechanism for a timepiece comprising:
- a regulator comprising a regulating member adapted to oscillate with a certain nominal amplitude and a certain period of oscillation;
- an energy distributing member provided with teeth and intended to be biased by an energy storage device;
- a pallet fork engaging with the teeth of the energy distributing member, said pallet fork being controlled by the regulator to periodically and alternately lock and release the energy distributing member so that said energy distributing member is biased by the energy storage device to move in incremental steps in a cycle of repetitive motion, and said pallet fork being adapted to transfer mechanical energy to the regulator during this cycle of repetitive motion;
- said mechanism comprising:
- a decoupling member elastically connected to the pallet fork by a first elastic link and to the regulating member by a second elastic link, said decoupling member being arranged to oscillate with a certain amplitude between first and second extreme positions and with the same period of oscillation as the regulating member;
- motion limiting means for imposing said extreme positions.
