Method for Adjusting Sensitivity of Load Detecting Device of Seat for a Vehicle
First Claim
1. A method for adjusting sensitivity of a load detecting device of a seat for a vehicle, the load detecting device including a plurality of load sensors outputting signals respectively so as to measure a load of an occupant seated on a seat cushion and arranged between a floor-side fixing member adapted to be fixedly mounted on a floor of the vehicle and a seat-side fixing member adapted to be fixed to the seat cushion of the seat, and a processing device inputted with the signals and processing the signals, the method comprising:
- a sensor assembling step for assembling the plurality of load sensors;
a seat assembling step for assembling the seat for the vehicle by arranging the plurality of load sensors assembled in the sensor assembling step between the floor-side fixing member and the seat-side fixing member;
a zero point adjusting step for obtaining a non-load output value by totaling values corresponding to the signals of the load sensors when no load is applied on the seat for the vehicle assembled in the seat assembling step and for memorizing the non-load output value in a memory of the processing device;
an adjusted output value calculating step for obtaining an adjusted output value by subtracting the non-load output value from a total output value including a total of the values corresponding to the signals of the load sensors when a predetermined load is applied on the seat for the vehicle;
a trimming coefficient calculating step for calculating a trimming coefficient by dividing a designed output value corresponding to the predetermined load by the adjusted output value; and
a trimming coefficient memorizing step for memorizing the trimming coefficient in the memory of the processing device.
