MICROMECHANICAL YAW-RATE SENSOR
First Claim
1. A micromechanical yaw-rate sensor, comprising:
- a first yaw-rate sensor element which outputs a first sensor signal containing information about a rotation around a first rotational axis;
a second yaw-rate sensor element which outputs a second sensor signal containing information about a rotation around a second rotational axis, the second rotational axis being perpendicular to the first rotational axis;
a coupling link which mechanically couples the first yaw-rate sensor element and the second yaw-rate sensor element to one another; and
a drive which drives the first yaw-rate sensor element, driving of the first yaw-rate sensor element by the drive also causing driving of the second yaw-rate sensor element due to the mechanical coupling by the coupling link.

Abstract
A micromechanical yaw-rate sensor comprising a first yaw-rate sensor element, which outputs a first sensor signal, which contains information about a rotation around a first rotational axis, a second yaw-rate sensor element, which outputs a second sensor signal, which contains information about a rotation around a second rotational axis, which is perpendicular to the first rotational axis, a drive, which drives the first yaw-rate sensor element, and a coupling link, which mechanically couples the first yaw-rate sensor element and the second yaw-rate sensor element to one another, so that driving of the first yaw-rate sensor element also causes driving of the second yaw-rate sensor element.
