Abstract
Seat springs as the frequency-determining component in a vehicle seat are assigned to an oscillating circuit. When there is a load on the vehicle seat, the inductance of the seat springs changes and thus the resonant frequency of the oscillating circuit changes. Occupancy of a seat is detectable in this way.
