Abstract

A load detecting device includes a plurality of load sensors which are disposed in a matrix shape and correcting means for setting at least one of the plural load sensors as a standard load sensor and for correcting level of output values of each load sensors to level of output value of the standard load sensor on the basis of the output values of each load sensors.

Claims

1. A load detecting device for a vehicular seat comprising:

a plurality of load sensors which are disposed in a matrix shape and

correcting means for setting at least one of the plural load sensors as a standard load sensor and for correcting a level of output values of each load sensor based on the level of the output value of the standard load sensor.

2. A load detecting device for a vehicular seat according to claim 1, wherein the load sensors are formed by printing and the standard load sensor is disposed at approximately a central portion of the matrix shape.

3. A vehicular seat provided with a load detecting device according to claim 1, wherein the correcting means sets as the standard load sensor a load sensor disposed at a central portion of the plural load sensors disposed in the matrix shape.

4. A load detecting device for a vehicular seat comprising:

a plurality of load sensors which are disposed in a matrix shape including a standard load sensor disposed at a standard line in the matrix shape and

correcting means for correcting a level of output values of each load sensor based on a level of the output value of the standard load sensor.

5. A load detecting device for a vehicular seat according to claim 4, wherein the load sensors are formed by printing in a row direction of the matrix and the standard line is a line which is disposed at approximately central portion of the matrix shape.

6. A vehicular seat provided with a load detecting device, the load detecting device comprising:

a plurality of load sensors disposed in a matrix shape and including a standard load sensor disposed at a central portion of the matrix; and

correcting means for correcting a level of output value of each load sensor based on the level of output value of the standard load sensor.

7. A vehicular seat provided with a load detecting device according to claim 6, wherein the load sensors are formed by printing and the standard load sensor is disposed at approximately a central portion of the matrix shape.
