Occupant discriminating method for vehicular seat
First Claim
1. An occupant discriminating method for a vehicular seat, which comprises a seat cushion frame, a load receiving member on the seat cushion frame on which the load of an occupant acts, springs which are interposed between the load receiving member and the frame and extend in accordance with the load, and displacement sensors which output electrical signals corresponding to the respective elongations of the springs, the occupant discriminating method comprising:
- first-stage determination step which determines the type of an occupant in the seat in accordance with the electrical signals; and
second-stage determination step which determines whether or not the result of determination by the first-stage determination step is maintained for a given period of time and settles the type of the occupant if the result of determination by the first-stage determination step is maintained for the given period of time.

Abstract
A flat spring of a vehicular seat is elastically supported by means of supporting springs that extend in accordance with the load of an occupant. The seat has displacement sensors, first-stage determination step, second-stage determination step, and third-stage determination step. The displacement sensors output electrical signals corresponding to the respective elongations of the springs. The first-stage determination step determines the occupant in the seat in accordance with voltage values delivered from the displacement sensors. The second-stage determination step determines whether or not the result of determination by the first-stage determination step is maintained for a given period of time. The third-stage determination step compares the result of determination by the second-stage determination step with the preceding result of determination and specifies the occupant in accordance with the result of the comparison.
