Claim:
1. A yaw rate sensor for detecting a rotational movement, comprising: a first sensor structure having a first oscillating mass coupled via a first deflection element to a drive structure, and configured to detect a first yaw rate around a first axis of rotation; a second sensor structure having a second oscillating mass coupled to the drive structure, and configured to detect a second yaw rate around a second axis of rotation and a third yaw rate around a third axis of rotation different from the second axis of rotation; and the drive structure coupled to the first and second oscillating masses and configured to provide a drive motion in a drive direction; wherein the first oscillating mass is drivable into a first drive oscillation along a first oscillation direction, the second oscillating mass is drivable into a second drive oscillation along a second oscillation direction different from the first oscillation direction, the first axis of rotation is perpendicular to the first oscillation direction, and the second and third axes of rotation are perpendicular to the second oscillation direction, and the first deflection element includes four pivot elements, each configured to pivot to produce the first drive oscillation along the first oscillation direction of the first oscillating mass in response to the drive motion in the drive direction of the drive structure, the drive direction being perpendicular to the first oscillation direction.
