Abstract

A cover material, in particular a seat cover material, having an upper side and a lower side and at least one seam that runs over at least a part of the cover material and that is visible on the upper side. An electrically conductive element that generates an electric field is arranged on the lower side in the region where the seam runs.

First claim

What is claimed is:

1. A vehicle seat assembly, comprising:
a vehicle seat, with a backrest ( 3 ), a seat part ( 2 ), and a seat cover ( 6 );
an electrically conductive element ( 7 ) set at an electric potential that differs from the ground potential and thereby generates an electric field; and
a control unit ( 8 ), which is coupled with the electrically conductive element ( 7 ) such that the electric field is modified when a user's finger approaches or touches an upper side of the seat cover ( 6 ) in the vicinity of a seam ( 4 , 4 ′, 4 ″, 4 ′″, 4 ″″), and wherein the control unit ( 8 ) receives an electric signal generated by a modification of the electric field.

2. The vehicle interior according to claim 1 , wherein the vehicle seat assembly has an electric seat function ( 9 ), that is accessible by the control unit ( 8 ) as a result of the generated signal.

3. The vehicle interior according to claim 2 , wherein the electric seat function includes at least one function selected from the group consisting of: backrest angle adjustment, seat length adjustment, seat height adjustment, illumination, seat ventilation, seat heating, seat depth adjustment, lumbar support adjustment, headrest adjustment, side bolster adjustment, and seat massage function.

4. The vehicle interior according to claim 1 , wherein the seam ( 4 , 4 ′, 4 ″, 4 ′″, 4 ″″) runs over at least a part of the seat cover ( 6 ) and is visible on the upper side of the seat cover ( 6 ), and the electrically conductive element ( 7 ) that generates the electric field is arranged on a lower side ( 6 a ) of the seat cover ( 6 ) in a region where the seam ( 4 , 4 ′, 4 ″, 4 ′″, 4 ″″) runs.

5. The vehicle interior according to claim 4 , wherein the electrically conductive element ( 7 ) is a strip with at least one electrically conductive section.

6. The vehicle interior according to claim 4 , wherein the electrically conductive element ( 7 ) is attached to the seat cover by the seam ( 4 , 4 ′, 4 ″, 4 ′″, 4 ″″) on the lower side.

7. The vehicle interior according to claim 4 , wherein the seam ( 4 , 4 ′, 4 ″, 4 ′″, 4 ″″) and the cover material ( 6 ) are not electrically conductive.

8. The vehicle interior according to claim 4 , wherein the cover material ( 6 ) is configured in multiple layers.

9. The vehicle interior according to claim 4 , wherein the electrically conductive element ( 7 ) is encapsulated so that the electrically conductive element ( 7 ) is impermeable to moisture.

10. The vehicle interior according to claim 4 , wherein the seam ( 4 , 4 ′, 4 ″, 4 ′″, 4 ″″) is not electrically conductive.

11. The vehicle interior according to claim 4 , wherein the cover material ( 6 ) is not electrically conductive.
