Abstract

A sensor for acceleration measurement, for example for automatic release of occupant protective devices in vehicles, especially power vehicles, in which during deceleration of the vehicle or vehicle part a control signal is produced. The sensor comprises a support, a pendulum with a seismic mass mounted on two bending bars formed in the support, resistances each provided on a respective one of the bending bars, and further resistances each arranged on the support in the region between the bending bars and on the pendulum in the region between the bending bars, the first mentioned resistances and the further resistances being connected in a Wheatstone bridge.
