Abstract
A seat state detecting apparatus is provided with a sensor unit including a plurality of pressure sensitive switch units connected in parallel to each other. Each of the pressure sensitive switch units is switched to an on state or an off state in correspondence to a pressure. A plurality of pressure sensitive switch units are arranged in the seat in a dispersed manner. The seat state detecting apparatus determines a load applied to the seat on the basis of the on/off state of a plurality of pressure sensitive switch units. Each of the pressure sensitive switch units includes a plurality of pressure sensitive switches connected in series to each other. Accordingly, it is possible to improve a reliability for determining that a load applied onto a seat surpasses a predetermined value.
