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.

Abstract: A seat belt lock with a Hall sensor for detection of a locking state of a seat belt lock having a metal seat belt lock frame arranged in a housing. The seat belt lock frame has an upper part and a lower part, connected to a define slit-like channel. A spring-loaded locking device for an inserted seat belt latch is mounted on the seat belt lock frame. A spring-loaded ejector for the inserted seat belt latch is arranged in the channel.

The Hall sensor is arranged on or in the seat belt lock frame and is covered by a metal shielding element, which extends essentially parallel to the seat belt lock frame and forms a flow concentrator.
