Classification: CPC B  G | IPC B

Claim 0:
1. A micromechanical component for a pressure sensor device comprising:
a substrate having a boundary surface formed by a substrate surface of the substrate and/or by at least one intermediate layer at least partially covering the substrate surface;
a frame structure, situated on the boundary surface, including a diaphragm whose inner diaphragm side borders on an interior volume, framed by the frame structure and having a reference pressure prevailing within, in such a way that the diaphragm is warped into the interior volume when a pressure prevailing on an outer diaphragm side facing away from the inner diaphragm side is above the reference pressure; and
a rocker structure suspended on the inner diaphragm side, which at least in an operating mode of the rocker structure is able to be set into a rocker motion by the diaphragm warping into the interior volume;
wherein when a pressure prevailing on the outer diaphragm side is above the reference pressure, but below a predefined minimum operating pressure, an open gap exists respectively between at least one stop face of the rocker structure and the boundary surface, which is closed only when the pressure prevailing on the outer diaphragm side becomes greater than or equal to the minimum operating pressure, whereby the rocker structure is transferred into the operating mode.
