    DESCRIPTION OF THE PREFERRED EMBODIMENTS

    [0040] Referring to the drawings, a vehicle seat 1 that is illustrated in FIG. 5 comprises a seat part 3 and a backrest 5 that is fastened to the latter. The backrest 5 has a load-bearing backrest structure and a cushion that covers the backrest structure. A foam part of the cushion is provided with a cushion cover 100 or is configured so as to be integral to the latter.

    [0041] The cushion cover 100 in a localized manner has a plurality of embossings 120, for example an emblem or a brand logo.

    [0042] The production of the cushion cover 100 is illustrated in FIGS. 1 to 4. In a first method step that is illustrated in FIG. 1, a surface layer 102, provided with a carrier layer 104, of the cushion cover 100 is disposed between a female mold 14, having a plurality of depressions 18, and a male mold 12, having a plurality of elevations 16, of a tool 10. The elevations 16 are complementary to the depressions 18. The depressions 18 in the exemplary embodiment are embodied as through bores such that a direct localized treatment of the surface layer 102, for example by heating, radiating, spraying, soaking, or the like, is possible during embossing. The thickness of the female mold 14 in the exemplary embodiment corresponds to approximately the height of the elevations 16 of the male mold 12.

    [0043] The female mold 14 and the male mold 12 are subsequently converged. The elevations 16 of the male mold 12 herein deform the surface layer 102 and the carrier layer 104 in that, by means of the elevations 16, material of the surface layer 102 and of the carrier layer 104 is pushed into the depressions 18 of the female mold 14. The tool 10 remains in a closed state for a defined period of time. The surface layer 102 and the carrier layer 104 are preferably heated in the tool 10 such that the deformation is performed at a temperature that is elevated in relation to room temperature. In a variation of the exemplary embodiment, the surface layer 102 can additionally be welded to the carrier layer 104 under the influence of high frequency, for example ultrasound.

    [0044] In a further method step that is illustrated in FIG. 2a, the surface layer 102 that is provided with the carrier layer 104 is removed from the tool 10. The surface layer 102 and the carrier layer 104 now have a plurality of embossings 120, a total of seven in FIG. 2a, which in a localized manner protrude from the surface layer 102 in relation to neighboring regions of the surface layer 102. Respective cavities 122 are located on the reverse side of the embossings 120.

    [0045] In a further method step that is illustrated in FIG. 3a, the cavities 122 are filled with inserts 106 that are composed of a foam material. This can be performed outside the tool 10, or the female mold 14 of the tool 10 is rotated and the surface layer 102 that is provided with the carrier layer 104 is inserted into the female mold 14. The cavities 122 of the surface layer 102 that is provided with the carrier layer 104 point upward. The cavities 122 are subsequently filled with foam.

    [0046] FIG. 4 shows a section through a cushion cover 100 which in further method steps is additionally provided with a foam tier 108 and a woven fabric layer 110. In variations of the exemplary embodiment the foam tier 108 and/or the woven fabric layer 110 can be omitted.

    [0047] FIGS. 7a to 10 show exemplary embodiments having dissimilarly molded embossings 120. However, the embossings 120 can also have shapes that deviate from the exemplary embodiments.

    [0048] FIGS. 7a and 7b show a linear arrangement of a plurality of circular-cylindrical pot-shaped embossings 120.

    [0049] FIGS. 8a and 8b show an arrangement of a plurality of elliptic pot-shaped embossings 120. FIG. 9 shows a section along a major semiaxis of one of the elliptic embossings 120.
