A longitudinal adjusting device for vehicle seats, whose backrest, which is adjustable in inclination positions which are selectable as the case may be, is swivelably connected with a seat part, has running rails and guide rails, wherein the seat part is fastened to the running rails. Each running rail is displaceable longitudinally in one of the guide rails fixed to the vehicle floor. A locking device secures at least one of the running rails to the respective guide rail in selectable longitudinal positions. A spring member supports at least one of the running rails at the guide rail for purposes of a forward displacement of the running rails, wherein the spring member is a spiral spring. A winding drum is rotatably supported on the running rail, wherein a first end of the spiral spring is associated with the running rail and a second end of the spiral spring is associated with the guide rail, wherein the second end of the spiral spring associated with the guide rail is held at the winding drum. A pull rope is fixed with one end to the winding drum and with the other end to the front area of the guide rail.
