Occupant weight detecting device
First Claim
1. An occupant weight detecting device comprising;
- a load detecting means for detecting a load applied to a seat body;
a calculating means for calculating an initial load value based upon a detected load value by the load detecting means and for calculating an occupant load value applied to the seat body by subtracting the initial load value from the detected load value; and
a filter means with a cutoff frequency so as to attenuate a fluctuation of the detected load value due to elements except a deterioration inherent to the load detecting means.

Abstract
An occupant weight detecting device includes a load detecting means equipped to a seat body for detecting a load applied to the seat body, a calculating means for calculating an initial load value during the seat body under an initial condition based upon a detected load value by the load detecting means and for calculating a value of an occupant load applied to the seat body by subtracting the initial load value from the detected load value, and a filter housed in the calculating means and possessing a cutoff frequency so as to attenuate a fluctuation of the detected load value generated due to an element other than a deterioration inherent to the load detecting means.
