Abstract: A flat spring of a vehicular seat is elastically supported by means of supporting springs that extend in accordance with the load of an occupant. The seat has displacement sensors, first-stage determination step, second-stage determination step, and third-stage determination step. The displacement sensors output electrical signals corresponding to the respective elongations of the springs. The first-stage determination step determines the occupant in the seat in accordance with voltage values delivered from the displacement sensors. The second-stage determination step determines whether or not the result of determination by the first-stage determination step is maintained for a given period of time. The third-stage determination step compares the result of determination by the second-stage determination step with the preceding result of determination and specifies the occupant in accordance with the result of the comparison.

Abstract translation: 通过支撑弹簧弹性地支撑车辆座椅的弹簧，所述支撑弹簧根据乘员的负载而延伸。 座椅具有位移传感器，第一阶段确定步骤，第二阶段确定步骤和第三阶段确定步骤。 位移传感器输出对应于弹簧的相应伸长率的电信号。 第一阶段确定步骤根据从位移传感器传递的电压值确定座椅中的乘客。 第二级确定步骤确定第一级确定步骤的确定结果是否保持给定的时间段。 第三级确定步骤将通过第二级确定步骤的确定结果与先前的确定结果进行比较，并根据比较结果指定乘客。
