Patent ID: 7384190

Claim:
A crown for a timepiece including a housing of axis X 1 inside which are arranged in particular: at least one first element, able to be deformed resiliently, cooperating in rotation about said axis X 1 , in at least a first direction of rotation, with a rigid element, as long as the rotational couple transmitted by one of said elements to the other is less than a predefined value beyond which said first deformable element is capable of being deformed to disconnect the rotational cooperation between said first element and said rigid element, wherein a pipe including, in the region of a first end, means for securing a winding stem, is disposed within the housing of axis X 1 wherein said resiliently deformable element is secured to said pipe whatever the value of the rotational couple, whereas said rigid element is fixed in relation to the crown, and wherein said deformable element cooperates in rotation with the inner periphery of the rigid element of annular shape.
