Abstract: The present invention concerns an apparatus for adjusting, without rails, the vertical and longitudinal position and the inclination of a vehicle seat (1) relative to a vehicle floor (4). The apparatus according to the present invention has at least two pivot levers (10, 14), spaced apart from one another in an adjustment direction (B), that are articulated respectively on the vehicle seat (1) and on the vehicle floor (4) by way of pivot pins (12a, 12b, 12c, 12d) extending parallel to one another. The pivot pins (12a, 12b; 12c, 12d), arranged on the vehicle seat (1) and on the vehicle floor (4), of at least one of the pivot levers (10, 14) are lockable independently of one another, the pivot lever (10, 14) having the lockable pivot pins (12a, 12b, 12c, 12d) comprising an additional pivot pin (12e) extending parallel to the pivot pins (12a, 12b, 12c, 12d) and thereby being subdivided into two lever segments (14, 16) joined in articulated fashion to one another.
