Patent ID: 7216895

Claim:
A seating detector, comprising: a plurality of cells provided at a seating surface of a seat to be defined by a two-dimensional array including rows and columns for detecting partial loads applied to the seating surface of the seat; an unevenness calculating means for calculating the number of cells when a partial pressure detected at the each cell is larger than a partial pressure detected at one abutting cell positioned next to the cell at one side thereof in one direction and larger than a partial pressure detected at the other abutting cell positioned next to the cell at the other side thereof in one direction, or when a partial pressure detected at the each cell is smaller than a partial pressure detected at one abutting cell positioned next to the cell at one side thereof in one direction and smaller than a partial pressure detected at the other abutting cell positioned next to the cell at the other side thereof in one direction; a determining means for determining that the seat is occupied by a child restraint system based on a comparison between the number of the cells calculated by the unevenness calculating means and a threshold.
