Abstract

La présente invention concerne un dispositif capacitif (2) dans un véhicule automobile pour détecter la présence d'un occupant à l'intérieur du véhicule, ledit dispositif comprenant - une première électrode (20) séparée d'une deuxième électrode (21) par un matériau diélectrique (22) pour former un capteur capacitif, ledit capteur capacitif étant disposé sur une surface d'un composant du véhicule, - un générateur de tension (23) agencé pour générer une tension alternative entre lesdites première et deuxième électrodes (20,21), et - un circuit de mesure de courant (24) agencé pour mesurer le courant entre la deuxième électrode et une masse électrique du véhicule, la présence dudit occupant à proximité dudit composant étant fonction du courant mesuré.
