Abstract

A motor vehicle seat includes a reclining or pivotable backrest, on which an electrical load is arranged and a transmission device for transmitting signals and/or power between the electrical load and a vehicle-side device. Signals and/or power can be contactlessly transmitted by the transmission device.

First claim

What is claimed is:

1. A motor vehicle seat comprising
a seat part having a seating surface;
a backrest pivotably positionable relative to the seating surface and having an electrical load arranged thereon;
a vehicle-side device; and
a transmission device operably coupled between the vehicle side device and the backrest and configured to contactlessly transmit an electrical signal between the vehicle-side device and the electrical load.

2. The motor vehicle seat according to claim 1 , wherein the transmission device is configured to inductively transmit the electrical signal by the transmission device.

3. The motor vehicle seat according to claim 1 , wherein the transmission device is configured to capacitively transmit the electrical signal by the transmission device.

4. The motor vehicle seat according to claim 1 , wherein the transmission device comprises a first transmission element arranged on the backrest and a second transmission element arranged on at least one of a vehicle side structure or a seat substructure adjacent to but not in contact with the first transmission element.

5. The motor vehicle seat according to claim 4 , wherein the backrest is pivotably positionable from an upright, locked use position into a horizontal, nonuse position, wherein the first and second transmission elements are configured to contactlessly transmit the electrical signal between the vehicle-side device and the electrical load when the backrest is in the use position.

6. The motor vehicle seat according to claim 5 , wherein the first and second transmission elements are configured to contactlessly transmit an attenuated electrical signal between the vehicle-side device and the electrical load when the backrest is in the nonuse position.

7. The motor vehicle seat according to claim 5 , wherein the first and second transmission elements are configured to not transmit the electrical signal between the vehicle-side device and the electrical load when the backrest is in the nonuse position.

8. The motor vehicle seat according to claim 7 , wherein the first and second transmission elements overlap each other at least in the use position of the backrest, and do not overlap each other in the nonuse position.

9. The motor vehicle seat according to claim 5 , wherein the backrest is configured to pivot within a predetermined first pivoting range having two or more use positions into which the backrest can be locked, wherein the first and second transmission elements are configured to contactlessly transmit the electrical signal between the vehicle-side device and the electrical load when the backrest is in the two or more use positions.

10. The motor vehicle seat according to claim 9 , wherein the backrest is configured to pivot within a predetermined second pivoting range between the first pivoting range and the nonuse position, wherein the first and second transmission elements are configured to contactlessly transmit an attenuated electrical signal between the vehicle-side device and the electrical load when the backrest is in the second pivoting range.

11. The motor vehicle seat according to claim 9 , wherein the backrest is configured to pivot within a predetermined second pivoting range between the first pivoting range and the nonuse position, wherein the first and second transmission elements are configured to not transmit the electrical signal between the vehicle-side device and the electrical load when the backrest is in the nonuse position.

12. The motor vehicle seat according to claim 5 , wherein the second transmission element is arranged on a vehicle-side plate fastened to the plate facing the backrest, wherein a pivoting axis of the backrest extends through the plate, and an electrical terminal of the second transmission element is arranged on a side of the plate facing away from the backrest.

13. The motor vehicle seat according to claim 12 , wherein the first transmission element is arranged on a backrest plate fastened to a side of the backrest facing the second transmission element, wherein the pivoting axis of the backrest extends through the backrest plate, and an electrical terminal of the first transmission element is arranged on the side of the backrest plate facing away from the second transmission element.

14. The motor vehicle seat according to claim 1 , wherein the electrical load is selected from a group consisting of a seat heater and a loudspeaker.

15. A motor vehicle comprising a vehicle body having a front seat position and a rear seat position located behind the front seat position and at least one motor vehicle seat according to claim 1 arranged in the rear seat position.

16. A motor vehicle seat comprising
a seat part having a seating surface;
a backrest pivotably positionable relative to the seating surface and having an electrical load arranged thereon, the backrest being pivotably positionable from an upright, locked use position into a horizontal, nonuse position;
a vehicle-side device; and
a transmission device operably coupled between the vehicle side device and the backrest and configured to contactlessly transmit an electrical signal between the vehicle-side device and the electrical load, the transmission device comprising a first transmission element arranged on the backrest and a second transmission element arranged on at least one of a vehicle side structure or a seat substructure adjacent to but not in contact with the first transmission element, wherein the first and second transmission elements are configured to contactlessly transmit the electrical signal between the vehicle-side device and the electrical load when the backrest is in the use position and are configured to not transmit the electrical signal between the vehicle-side device and the electrical load when the backrest is in the nonuse position.
