ABSTRACT:
A Hall effect device (60) is exposed to a magnetic field having flux lines extending in a first direction relative to the Hall effect device (60) if a seat belt tongue (16) is not locked in a seat belt buckle (12). The Hall effect device (60) is exposed to a magnetic field having flux lines extending in a second, opposite direction relative to the Hall effect device if the tongue (16) is locked in the buckle (12). The output of the Hall effect device (60) indicates whether or not the tongue (16) is locked in the buckle (12).
