PCT No. PCT/DE91/00853 Sec. 371 Date Jun. 19, 1992 Sec. 102(e) Date Jun. 19, 1992 PCT Filed Nov. 2, 1991 PCT Pub. No. WO92/08989 PCT Pub. Date May 29, 1992.A sensor for automatically triggering safety devices in motor vehicles has a housing a having a recess, a body arranged in the housing so as to serve as a seismic mass and to trigger a control signal when a predetermined threshold value is exceeded, a permanent magnet enclosed by a region of magnetically nonconductive material, a Hall element arranged in the body in working connection with the permanent magnet and comprising magnetically conducting material. The Hall element substantially evaluates magnetic flux lines running parallel to a polarization direction of the permanent magnet, so that the Hall element evaluates the magnetic flux lines running parallel to the polarization direction of the permanent magnet in a basic position, and evaluates the magnetic flux lines running in an opposite direction in a tilting position.
