Adjustment device for a vehicle seat as well as a vehicle seat

An adjustment device for a vehicle seat comprising

• a first adjuster and a second adjuster adjustable in relation thereto, where on the first adjuster a toothed rack with an interlocking is hinged, and on the second adjuster a pinion is pivoted, where the toothed rack collaborates with a spring means coupled to the second adjuster, the spring means biasing the toothed rack in the direction of the pinion,
• the interlocking of the toothed rack engaging with the pinion in such a way that the toothed rack is adjusted when the pinion is rotated about a pinion axis, where by means of such adjustment of the toothed rack the adjusters can be moved in relation to one another,
• wherein a toothed rack blocking element is affixed to the second adjuster, and the toothed rack, when adjusted, runs between the toothed rack blocking element and the pinion,
• wherein the spring means extends as a separate component between the toothed rack blocking element and a spring blocking element spaced apart there from, the spring means comprising a curvature oriented towards the toothed rack in a middle region located between the toothed rack blocking element and the spring blocking element, the curvature being in contact with the toothed rack at a pressure point while exerting a pressure force so as to bias the toothed rack in the direction of the pinion, the curvature being formed by attaching a local thickening to a surface of the spring means in a direction facing an upper side of the toothed rack, the local thickening of the curvature pressing at the pressure point against the upper side of the toothed rack with the pressure force.
