<p>A seat weight measuring apparatus that simplifies the circuit configuration of the load sensors to reduce the circuit costs and which, when the load sensors fail, immediately detects the failure of the load sensors, thereby improving the reliability. In the case where four load sensors are arranged at four locations, for example front and rear on both sides, of the bottom of the automotive seat, the seat weight measuring apparatus includes two pairs of load sensors, a detection circuit for detecting a difference between outputs from the two antiphase-connected pairs of load sensors, and a seat weight calculator for calculating the weight of the automotive seat based on an output from the detection circuit. This can simplify the circuit configuration and eliminate problems of circuit costs and reliability. <IMAGE></p> |
