Classification: CPC B  F | IPC B  F

Claim 1:
2. The parking brake of claim 1, wherein the inhibitor device comprises:
(a) a first disk adapted to be keyed onto the drive shaft, having a rotation axis and comprising a perimeter edge with a set of first recesses,
(b) a second disk, coaxial to the first disk, mounted so as to be able to perform angular movements with respect to the first disk about the rotation axis of the first disk, and that can be mounted idle with respect to the drive shaft; wherein the second disk comprises a perimeter edge with a set of second recesses, the first recesses and the second recesses having an approximately equal angular pitch; and
(c) a centrifugal mass adapted to rotate at the angular speed of the first disk and connected to the second disk so that when the rotation speed of the first disk is higher than a minimum speed, the centrifugal mass holds the second disk in an angularly staggered position with respect to the first disk, so that the first recesses are angularly staggered with respect to the second recesses, wherein the locking member is shaped so as to be fitted into the first recesses and into the second recesses, when the first recesses and the second recesses are in an angular position phased with respect to each other; wherein the insertion of the locking member in the first recesses and in the second recesses is prevented when the second disk is in an angularly staggered position with respect to the first disk.
