Patent ID: 8213066

Claim:
A micromechanical actuator, in particular a micro-mirror scanner, with an actuator unit in an outer frame, which is suspended via two torsion elements in the outer frame extending along an outer tilting axis of the actuator unit, and electrostatic tilt drives of intermeshing first and second comb-type or finger-type electrodes, which are vertically offset from each other, and of which the first electrodes are rigidly connected with the outer frame and the second electrodes are connected with the outer frame via an outer connecting element, and with the actuator unit via an inner connecting element, wherein the outer connecting element is designed such that it enables a bending in a vertical direction to a plane of the outer frame, and wherein the inner connecting element comprises two springs, which extend in parallel to the outer tilting axis, in each case are connected in a region of the actuator unit that lies closer to the outer tilting axis than an edge of the actuator unit opposite to the outer tilting axis, and which are designed and arranged such that they are rigid in the vertical direction and are flexible at a right angle to the vertical direction.
