Abstract
A method for detecting the displacement position of a vehicle seat is described. When the vehicle seat is being displaced, a magnetic field-sensitive sensor device monitors a change of one magnetic field component and depending on the output signal which has been generated by the sensor device, a conclusion is drawn about the adjustment position of the vehicle seat. The magnetic field-sensitive sensor device is displaced relative to a measuring section using the magnetic field-sensitive device. An absolute value of the magnetic field strength of a magnetic field whose magnetic field strength changes essentially continuously along a longitudinal extension of the measuring section is detected and converted into an absolute displacement position of the vehicle seat.
