Abstract

An acceleration sensing device includes a rotational speed sensor which is mounted on a substrate and detects rotational speed, at least one oscillating structure with a deflectable seismic mass, and an acceleration sensor that detects linear acceleration and has at least one additional seismic mass which is suspended on flexible elements so that it can be deflected. The seismic masses of the two sensors are deflected independently of one another.
