ABSTRACT:
In a passenger weight measuring apparatus, each of bend parts of front and rear brackets for supporting a seat to a vehicle main body side becomes bent and deformed in response to the load applied by the weight of the passenger sit in the seat. A load sensor on each the bend part detects the load based on the bend deformation and outputs a voltage signal of magnitude responsive to the load to a signal processor. The processor generates a load detection signal clamped in the voltage range corresponding to a preset passenger weight load range from the voltage signal and outputs the load detection signal to an output terminal. When the detected load is a collision load set in a load region out of the load range, the processor outputs an abnormal load detection signal different from the load detection signal to the same output terminal.
