Abstract:
1. A micromechanical acceleration sensor comprising: at least one substrate; a first comb structure; an airbag sensor including at least a first frame including a second comb structure is suspended on the substrate by at least one spring element, and is deflected with respect to the substrate when a first acceleration greater than a first acceleration threshold of 25 g acts in a first axis, such that the second comb structure moves with respect to the first comb structure thereby allowing the sensor to sense movement in the first axis; and an electronic stability program sensor including at least a first seismic mass which is suspended on the first frame or an additional frame by at least one torsion spring element, and is deflected rotationally with respect to the first frame or the additional frame when a second acceleration less than a second acceleration threshold of 10 g acts in a second axis perpendicular to the first axis, such that the first seismic mass moves with respect to at least one electrode thereby allowing the sensor to sense movement in the second axis.
