<p><P>PROBLEM TO BE SOLVED: To provide a vehicular seat device having excellent occupant seating detection sensitivity even if buried in a seat while superimposed with a seat heater, and a preferable manufacturing method thereof. <P>SOLUTION: A lower side electrode 12 is disposed between an upper side electrode 11 and a seat heater 8, alternating current voltage working together with alternating current voltage applied to the upper side electrode 11 is applied to the lower side electrode 12. Therefore, the deterioration of detection sensitivity by parasitic electrostatic capacitance between the seat heater 8 alternatingly regarded as a constant electrical potential electrode and the upper side electrode 11 is suppressed. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
