A device for determining a neutral position of two components (1, 2) that are displaceable relative to one another, comprising an adjustment device for moving the components (1, 2) into any arbitrary relative position and a positional sensor (9) for detecting the relative position, as well as path marker (6) located on the first component (1) and a marker sensor (8) provided on the second component (2) to detect the path marker (6) in a detection region (7), characterized in that in the neutral position the components (1, 2) are aligned with each other in such a manner that the path marker (6) is arranged outside the detection region (7) of the marker sensor (8), wherein the distance (10) between the detection region (7) and the path marker (6) is known, and the device comprises a data processing installation that is linked to the marker sensor (8) and the positional sensor (9), said installation determining the neutral position, when there is detection of the path marker (6) by the marker sensor (8) on the basis of the relative position detected by the positional sensor (9) and the known distance (10) between the detection region (7) of the marker sensor (8) and the path marker (6).
