Abstract
The device includes a barrel ( ) inserted in the kinematic chain between the rotor ( ) of the generator ( ) and the oscillating weight ( ). The barrel includes a spiral coiled spring ( ) and a sliding strip ( ), wound in the same direction as the spiral coiled spring over the length of a turn, without any mechanical connection with the spring, but forming a protective envelope in the open position in case of shock. The shockproof device can be applied to the generator of a wristwatch.
