PROBLEM TO BE SOLVED: To alarm a sitting person and recommend a right posture by detecting sitting on a seat, a sitting posture, a posture deviated from the posture suitable for the seat. SOLUTION: Variation of static capacity between a common electrode 12-1 in the vicinity of an objective vehicle seat and a spine detecting electrode 12-1 set on a spine contact area on the seat back and a hip detecting electrode 12-2 set on the hip contact area on the seat cushion is converted to detection voltages E1, E2 to be outputted values to detect and monitor a condition. The values outputted by the detecting electrodes are compared to prescribed detecting values K (K1, K2), Ks (Ks1, Ks2) to discriminate sitting or not, the sitting posture, and fatigue. If the outputted values E1, E2 do not satisfy a prescribed condition, an alarm and a recommendation therefore are displayed by letters on a display 42. |
