Capacitive object recognition method in vehicles

The method involves using a capacitor (2,3) in a seat back part and in a sitting part with capacitances influenced by an object. The capacitors are subjected to an alternating voltage, the time variation of their capacitances is determined and a table derived for assessment of the object. If both assessments of the object agree regarding the type of object an occupant protection device associated with the seat is suitably activated as required.
