摘要： An electrode unit for detecting whether a seat is occupied or not (occupancy conditions) is embedded in a seat of an automotive vehicle together with an electrically powered seat heater. Both of the electrode unit and the seat heater are flat, and the electrode unit is laminated on the heat heater. The electrode unit is composed of an upper electrode, a lower electrode and an insulating film disposed between both electrodes. The occupancy conditions are detected based on changes in a capacitance between the upper electrode and a member grounded to a vehicle body. To reduce a capacitance between the upper electrode and seat heater and to thereby improve sensitivity of the detection of the occupancy conditions, an alternating voltage that alternates in accordance with an alternating voltage supplied to the upper electrode is supplied to the lower electrode.

摘要： A passenger seat device includes a seat heater embedded in a seat and a detector electrode embedded underneath the seat heater. Electric power is supplied to the seat heater from an on-board battery through seat heater switches. Alternating voltage or current is supplied to the detector electrode. The detector electrode potential relative to the ground is lowered when the seat is occupied by a passenger. The changes in the potential of the detector electrode is detected by an occupant detector including a microcomputer. The detection is performed when the seat heater is brought to a floating state to suppress an amount of capacitance formed between the seat heater and the detector electrode. Thus, a sensitivity of the occupant detector is improved. The detector electrode may be eliminated, and the occupant conditions may be detected based on a potential of the seat heater to which alternating current or voltage is supplied.

摘要： A passenger seat device includes a detector electrode for detecting occupancy of the seat, a seat heater powered by an on-board electric power source, and a waterproof sheet for preventing water permeated into the seat from reaching the seat heater. Whether the seat is occupied or not is detected based on changes in an impedance coupled to the detector electrode. The impedance is affected by the water if it reaches the seat heater, and a sensitivity of the occupancy detection is adversely affected. A shielding electrode insulated from the detector electrode and disposed between the detector electrode and the seat heater may be provided to reduce an amount of parasitic capacitance formed between the detector electrode and the seat heater. An alternating voltage may be supplied to the detector electrode and the shielding electrode.
