1. A device for calibrating a belt-force sensor, comprising:
- a detecting arrangement to detect an unloaded state of a belt-force sensor, the detecting arrangement including an arrangement for detecting a belt-buckle state; and
an arrangement to set a measured value of the belt-force sensor to zero when the belt-force sensor is in the unloaded state in order to calibrate the belt-force sensor.

Abstract
A device and a method for calibrating a sensor, e.g., a force sensor such as a belt-force sensor, which allow reliable calibration of the sensor in a simple manner to counteract age-related distortion of measured values. The device for calibrating a sensor includes an arrangement for detecting at least one defined state of the sensor. When the sensor is in a defined state thusly detected, a corresponding adjustment of the measured value of the sensor may be implemented within the framework of the method.
