Sitting passenger detecting apparatus and sitting passenger detecting method

摘要

A sensor attaching portion of an upper rail and a sensor attaching portion of a cushion frame are provided with a sensor attaching plate having a sensor disposed thereon. The upper rail and the seat cushion frame are connected with a bracket at a position facing the sensor attaching plate. When the passenger sits on the seat, the seat cushion frame moves down and a bent portion of the bracket is pressed and deformed downwards. At this time, the center in the vertical direction of the sensor attaching plate is bent outward in the lateral direction of the seat. The sensor serves to detect the generated deformation.
