DRIVE SYSTEM FOR ROTATING A FIRST DEVICE RELATIVE TO A SECOND DEVICE ABOUT AN AXIS OF ROTATION

A drive system for rotating a first device for a vehicle about an axis of rotation relative to the vehicle. The system includes a support a support that is capable of relative movement relative to the first support, a piezoelectric element that is secured to the second support, and the second support and/or the piezoelectric element fixed to the first device, a friction surface; and at least one tip that is secured to the piezoelectric element. The piezoelectric element is configured to impart a movement to of the tip(s) when the piezoelectric element is supplied with an electrical voltage. The tip(s) are configured such that one end of the tip(s) comes into contact with the friction surface during at least a portion of the movement in order to allow relative movement between the first support and the second support about the axis of rotation.
