To sense the occupancy status of the seat surface of a seat, in particular in a vehicle, an electrically conductive foamed plastic is used, at least in sections, in the seat surface, and a signal corresponding to the resistance value between a top-side and a bottom-side electrode is utilized for discrimination purposes to determine whether the seat is occupied or not. An array of a plurality of parallel strips or a matrix of patches of the conductive foamed plastic permits a more thorough discrimination in terms of the occupying object or the occupying person.
