Abstract:
1. A seat sensor for a vehicle seat having a seat face portion, the seat sensor comprising: a plurality of sensor cells, each of which is disposed to the seat face portion of the vehicle seat, the each of the plurality of sensor cells having two electrodes that are arranged to face with each other, one of the two electrodes contacting an other one of the two electrodes to make the each of the plurality of sensor cells become electrically conductive when the each of the plurality of sensor cells is applied with a load, wherein: a first one of the plurality of sensor cells is displaced from a second one of the plurality of sensor cells in a longitudinal direction of the vehicle and in a transverse direction of the vehicle; one of the two electrodes of the second one of the plurality of sensor cells is directly and exclusively connected in series with one of the two electrodes of the first one of the plurality of sensor cells; a third one of the plurality of sensor cells is displaced from the second one of the plurality of sensor cells in the longitudinal direction of the vehicle and in the transverse direction of the vehicle, the third one of the plurality of sensor cells being displaced from an imaginary straight line that connects the first one and the second one of the plurality of sensor cells; and an other one of the two electrodes of the second one of the plurality of sensor cells is directly and exclusively connected in series with one of the two electrodes of the third one of the plurality of sensor cells.
