Abstract: A backrest of a vehicle seat includes an armature and an upholstery fixed to the armature. The upholstery has a slit for accommodating a headrest support rod by relative movement of the upholstery with respect to the armature in a longitudinal direction of the vehicle seat. The backrest further includes first and second trim elements. Each trim element forms a notch. The notches of the first and second trim elements define a passage for a headrest support rod. The second trim element partially covers the slit in the upholstery. The first and/or the second trim elements is/are in contact with the upholstery.

Abstract: An apparatus for connecting first and second seat areas is provided. The first and second seat area extend substantially with each other and each of the first seat areas have a corresponding second seat which it is connected to. The apparatus comprises a receiving bore fixed to one of the first and second seat areas. A threaded stem penetrates at least one connected set of the first and second areas crosswise through the receiving bore. The threaded stem has a conical spreading area and bears a nut on the side opposite the conical spreading area such that the threaded stem is freely movable axially on one side. A spreading bush encompasses the threaded stem.
