Abstract
Methods for enhancing the sliding performance of an adjusting device for longitudinal adjustment of a vehicle seat are disclosed. The adjusting device comprises a first rail and a second rail movably guided relative to the first rail. Friction-reducing members are disposed between the two rails in a bearing area. The geometry and dimensions of the friction-reducing members are precisely adjusted in accordance with the geometry and dimensions of the two rails in the bearing areas, which are measured separately. The friction-reducing members may be produced using additive manufacturing technology, with a geometry and dimensions precisely in accordance with the geometry and dimensions of the two rails. The friction-reducing members may also be produced using conventional injection molding, whereas the geometry and dimensions of the friction-reducing members are adjusted subsequently by varying the thickness of friction-reducing layers or coatings applied to outer surfaces of the friction-reducing members using e.g. ablative techniques.
