Seat occupant detection apparatus

摘要

A beam is mounted to a mounting flange. A seat pan is mounted to opposite end portions of the beam. Provided near a middle portion of the beam is a sensor unit for detecting flexure of the middle portion of the beam. The sensor unit has a sensor beam whose length is sufficiently less than the distance between fulcrums of the beam, and a transmission member that transmits the flexure of the beam occurring at a middle point thereof to the sensor beam. The sensor beam is provided with a strain sensor.
