1. A parking brake for a motor-driven vehicle, the parking brake comprising:
an inhibitor device, adapted to be associated to a drive shaft for rotating therewith, the inhibitor device being actuated by means of centrifugal force; and
a locking member adapted to engage the inhibitor device;
wherein the inhibitor device is configured to move from:
a first angular position in which the inhibitor device prevents the engagement of the locking member when said drive shaft rotates at a rotation speed greater than a minimum speed,
to a second angular position in which the inhibitor device allows the engagement of the locking member when said drive shaft rotates at a rotation speed lower than said minimum speed; and
wherein said inhibitor device is actuated by means of a centrifugal force, correlated to said rotation speed.
