Abstract
A system for detecting the weight of a person seated in a vehicle seat includes a pair of load sensor beams. Each load sensor beam has an intermediate section extending between a pair of opposite end sections. The opposite end sections of the load sensor beams are connected to a base frame of the vehicle seat. The load sensor beams are also connected to a seat pan of the vehicle seat that is positioned adjacent the base frame. The end sections of the load sensor beams are connected to opposite sides of the seat pan so that a plurality of loads generated by the weight of a person sitting on a seat cushion carried by the seat pan are transmitted to the intermediate sections of the load sensor beams. At least one sensor is mounted on the intermediate section of each load sensor beam for outputting signals representative of the plurality of loads generated by the weight of the person sitting on the seat cushion.
