The micromechanical sensor element

The micromechanical sensor element (1) having a substrate (2) and the substrate (2) suspended first seismic mass (10), which acceleration acting by a perpendicular to a main plane (100) from a first rest position, can be deflected, wherein the micro-mechanical sensor element ( 1) has a second seismic mass (20) which can be deflected by acceleration from a second rest position, said perpendicular (to the main extension plane 100) is provided an at least partial overlap of the first seismic mass (10) to the second seismic mass (20) characterized in that the first seismic mass (10) by means of a first coupling means (11) is substantially rotatably rotatably second about a first axis of rotation (12) and the second seismic mass (20) by means of a second coupling means (21) is essentially a axis of rotation (22) directly or indirectly to the substrate (2) is fixed.
