Abstract
A seat load measuring system for use in a vehicle occupant protection device for a vehicle seat has a zero point adjusting capability. The seat load measuring system comprises four weight sensor assemblies; a hub assembly for collecting the weight sensor outputs and providing an output determined by the weight sensor outputs; and means for communicating a user's desire for a zero point adjustment to each weight sensor assembly. Each weight sensor assembly includes a zero point adjusting section, which receives an output from the communication means for executing a zero point adjusting operation. If a zero point of a weight sensor assembly is not within a predetermined range, the zero point adjusting section may providing an alert. A zero point adjusting command may be entered by a command input device and passed to the zero point adjusting section. Alternatively, the zero point adjustment may be initiated through a momentary switch provided in the hub assembly.
