Abstract
A sensor, particularly for automatic release of occupant safety devices in power vehicles in the event of an accident, the sensor comprises a housing which forms a closed chamber; a body located in the housing and formed as a seismic mass, the closed chamber of the housing being completely filled with a fluid, the body being formed as a pendulum of a predetermined length, the chamber having a wall on which a boundary layer of the fluid is formed, the chamber having in all swinging direction of the pendulum a radius which is greater than the length of a pendulum and the boundary layer of the fluid formed on the wall of the chamber, the pendulum and the fluid having specific weights which differ from one another, the pendulum and the fluid being selected so that a friction during movement of the pendulum relative to the fluid leads to an aperiodecal damping of the pendulum.
