Die Erfindung betrifft eine Verstelleinrichtung für einen Fahrzeugsitz, welche mindestens ein aus einem hochmanganhaltigen Stahl bestehendes Beschlagteil (1, 2) umfasst. Es ist vorgesehen, dass das Materialgefüge mindestens eines Beschlagteiles (1, 2) in einem Bearbeitungsbereich (B-n) unter gleichzeitiger Ausbildung mindestens einer spezifischen Teilkomponente (1A, 1A', 1C, 1D, 2A, 2C) des mindestens einen Beschlagteiles (1, 2) kalt bearbeitet und dadurch lokal verfestigt wird. The method involves forming material structure of one fitting portion (1,2) in a machining region with the simultaneous formation of one specific subcomponent of one fitting portion. The material structure of fitting portion is locally solidified. One collar (1C,2C) and/or one bead (1D) of the fitting portion is formed in the corresponding processing region. An inner tooth (1A) and/or external tooth system (2A) is formed in the corresponding processing region. An independent claim is included for an adjusting device.
