Abstract: The present disclosure relates to a seat height adjustment device for adjusting the height of a seat cushion in relation to a seat frame, in particular, an upper rail, the seat height adjustment device comprising an actuating device, which may be, in particular, an electric motor, with a toothed pinion driven by the actuating device, and a toothed gear rack, the toothed gear rack comprising a hinge end for hinging onto the vehicle seat, and a front end including a gear rod region engaging with the toothed pinion, for adjusting the hinge end upon rotation of the toothed pinion. The present disclosure provides that the toothed gear rack is hot forged, the toothed gear rack comprises, between the hinge end and the gear rod region, a reinforced region, and the reinforced region comprises a profile.

Abstract: An adjustment arrangement for an adjustment device of a vehicle seat comprises a transverse tube and at least one connecting part connected fixedly in terms of rotation to the transverse tube. The transverse tube is inserted into a bore in the connecting part.

Abstract: A vehicle seat structural component comprises a transverse tube and a structural element, in particular a vehicle seat side frame element the transverse tube is connected to the structural element in a connecting region. The structural element comprises a conical sleeve the structural is arranged captively in axial direction between deformed sections. One section is a curling wherein the conical sleeve is also arranged captively in radial direction.

Abstract: A height adjustment device of a motor vehicle seat and a method for the production thereof includes a transverse pipe and a pair of links. The transverse pipe has two end-side bearing regions which merge in a central region having a larger diameter and each link rests on a bearing region of the transverse pipe.

Abstract: A method for producing a component comprising a row of teeth for adjusting a motor vehicle seat. A method of producing the component includes the row of teeth being pre-cut to its raw contours and subsequently heated and, in this state, shaped into its final contours in a stamping tool, or in that the region of the component in which the row of teeth is to be formed is heated and subsequently, in this state, cut to its final shape in punching tool.
