Abstract

A device for inductively transferring electrical energy and/or data from a primary-sided carrier to at least one positionable secondary-sided recipient includes at least one primary-sided coil arrangement, which inductively interacts with at least one secondary-sided coil arrangement. Meander-shaped windings of a predeterminable winding number of the primary-sided and/or secondary-sided coil arrangement are arranged on at least one flexible carrier by embroidering a high frequency strand, and the meander-shaped windings have straight courses in the region of crossovers of the embroidered high frequency strands.

First claim

What is claimed is:

1. A device for inductively transferring electrical energy and/or data from a primary-sided carrier to at least one positionable secondary-sided recipient comprising
at least one primary-sided coil arrangement; and
at least one secondary-sided coil arrangement;
wherein the at least one primary-sided coil arrangement transfers the electrical energy and/or data to the at least one secondary-sided coil arrangement by electromagnetic induction;
wherein the at least one primary-sided coil arrangement or the at least one secondary-sided coil arrangement comprises an embroidered high frequency strand configured to carry electrical energy and/or data and with a predeterminable winding number embroidered on at least one flexible carrier so as to have meander-shaped windings with crossover regions where a first portion of the embroidered high frequency strand crosses over a second portion of the embroidered high frequency strand; and
wherein the meander-shaped windings are not embroidered in the crossover regions so as to have straight courses without punctures in the at least one flexible carrier in the crossover regions of the embroidered high frequency strand.

2. The device according to claim 1 , wherein the individual windings of several identical meander-shaped windings are arranged on the at least one flexible carrier in relation to at least one folding line in such a way that the meander-shaped windings come to rest one above the other offset in relation to one another by folding together the at least one flexible carrier along the at least one folding line.

3. A method for producing a device for inductively transferring electrical energy and/or data, comprising:
providing first and second flexible carriers; and
embroidering first and second high frequency strands configured to carry electrical energy and/or data on the first and second flexible carriers so that the first flexible carrier has a primary-sided coil arrangement comprising an embroidered first high frequency strand configured to have a primary-sided meander-shaped winding with crossover regions where a first portion of the embroidered first high frequency strand crosses over a second portion of the embroidered first high frequency strand and the second flexible carrier has at least one secondary-sided coil arrangement comprising an embroidered second high frequency strand configured to have at least one secondary-sided meander-shaped winding with crossover regions where a first portion of the embroidered second high frequency strand crosses over a second portion of the embroidered second high frequency strand;
wherein the primary-sided meander shaped winding and the at least one secondary-sided meander-shaped winding are not embroidered on the first and second carriers in the crossover regions so as to have straight courses without punctures in the first and second carriers in the crossover regions.

4. The method according to claim 3 , further comprising arranging several identical secondary-sided meander-shaped windings on the second flexible carrier by embroidering.

5. The method according to claim 4 , further comprising embroidering the secondary-sided meander-shaped windings relative to at least one folding line onto the second flexible carrier in such a way that the secondary-sided meander-shaped windings come to rest one above the other offset in relation to one another by folding together the second flexible carrier along the at least one folding line.
