ABSTRACT:
An acceleration sensor for the automatic triggering of occupant protection systems in vehicles comprises a liquid which is moved in a housing as a function of the acceleration, with a detector which responds to a critical acceleration value. The housing is a level tube which is aligned relative to the acceleration to be determined and contains both the liquid and an indicating medium. The detector responds to the position of the indicating medium, as it moved in the liquid as a function of the acceleration.
