Abstract
A vehicle seat is provided in combination with a seat heater and a capacitive occupant detection system. The seat heater comprises a seat heating element disposed in the vehicle seat while the capacitive occupant detection system comprises a measurement circuit and an electrode arrangement, which is also disposed in the vehicle seat. The electrode arrangement includes a sensing electrode and a shielding electrode. The measurement circuit is operatively connected to the sensing electrode and to the shielding electrode and configured to keep the sensing electrode and the shielding electrode at substantially the same electric potential during the capacitive measurement. Of the seat heating element, the sensing electrode and the shielding electrode, the seat heating element is closest to a seating region of the vehicle seat and the sensing electrode is arranged between the seat heating element and the shielding electrode.
