Abstract

The invention relates to a vehicle seat having a seat part, having a backrest part and having an upholstery part for upholstering the seat part, wherein the upholstery part comprises an upholstery part cover element, a carrier layer element for supporting the upholstery cover element, an upholstery core element, a main upholstery element and a barrier layer, and wherein the main upholstery element is spatially separated by the barrier layer from the carrier layer element, the upholstery core element and the upholstery part cover element, the barrier layer having a seamless barrier layer element, which is arranged continuously as a strip product directly on the main upholstery element.

Claims

1. A vehicle seat having a seat part, having a backrest part and having an upholstery part for upholstering the seat part, wherein the upholstery part comprises an upholstery cover element, a carrier layer element for supporting the upholstery cover element, an upholstery core element, a main upholstery element and a barrier layer, and wherein the main upholstery element has an upper surface with side edges that define a width of the seat part, wherein the main upholstery element is spatially separated by the barrier layer from the carrier layer element, the upholstery core element, and the upholstery cover element, characterized in that the barrier layer is seamless and is positioned continuously and directly on the main upholstery element, wherein the barrier layer is applied over the entire upper surface of the main upholstery element, and therefore continuously and directly on the entire upper surface of the main upholstery element in the longitudinal direction of the seat part and also with regard to a width of the seat part transverse to the longitudinal direction, wherein the upholstery core element is limited to a central level region having a width less than the width of the seat part and does not extend laterally into two additional functional regions.

2. The vehicle seat according to claim 1, wherein the barrier layer is arranged spaced apart from the upholstery core element.

3. The vehicle seat according to claim 1, wherein the barrier layer comprises a polyurethane film and, in particular, has a thickness of between 0.25 μ

m and 1.5 μ

m.

4. The vehicle seat according to claim 1, wherein the upholstery core element is arranged embedded between the carrier layer element and the upholstery cover element.

5. The vehicle seat according to claim 1, wherein the upholstery core element comprises a cut foam, a reticulated foam or a spacer fabric and, in particular, has a thickness of between 3 mm and 50 mm.

6. The vehicle seat according to claim 1, wherein the carrier layer element comprises a laminating foam and, in particular, has a thickness of between 1 mm and 10 mm.

7. The vehicle seat according to claim 1, wherein at least one of the upholstery cover element, the carrier layer element and the upholstery core element are produced from a strip product.
