Title:
MICROMECHANICAL SENSOR UNIT FOR DETECTING ACCELERATION
Document Type and Number:
WIPO Patent Application WO/1995/027216
Kind Code:
A1
Abstract:
A micromechanical sensor unit for detecting acceleration has at least one pendulum with a spiral spring (B) and a seismic mass (P), a support (E) for each pendulum and at least two position sensors (S). Each position sensor (S) and its pendulum form a switch with a defined triggering threshold and at least two switches respond to the same direction of acceleration. At least one switch is a safing switch (SS) with a separate sensor signal tapping.
