Claims

1.-13. (canceled)

14. A heat pad comprising at least one or more heat cells, wherein at least one of the one or more heat cells has a shape of at least two concentrically arranged rings joined to one another via lines and comprising a heat-generating substance mixture which comprises a heat-generating material mixture comprising at least iron powder and carbon powder.

15. The heat pad of claim 14, wherein at least one of the one or more heat cells has a shape of a target.

16. The heat pad of claim 14, wherein at least a part of a surface of the pad has an adhesive layer thereon.

17. The heat pad of claim 14, wherein a defined amount of the heat-generating material mixture is fully surrounded by two polymer films bonded to one another, at least one of the polymer films being oxygen-permeable.

18. The heat pad of claim 14, wherein a defined amount of heat-generating material mixture is enclosed in a tube or a hose, the tube or hose consisting of an oxygen-permeable material.

19. The heat pad of claim 14, wherein the one or more heat cells are exchangeable.

20. The heat pad of claim 14, wherein the heat pad comprises at least four heat cells in annular form.

21. The heat pad of claim 20, wherein the heat pad is in the form of a triangle which has concave recesses in its sides and is rounded off at its corners.

22. The heat pad of claim 25, wherein the heat pad has a rectangular elongated form.

23. The heat pad of claim 22, wherein the heat pad comprises at least two cells in annular form arranged successively in longitudinal direction.

24. The heat pad of claim 21, wherein the heat cells in annular form are configured as targets bonded to one another.

25. The heat pad of claim 23, wherein the heat cells in annular form are configured as targets bonded to one another.

26. The heat pad of claim 14, wherein the heat-generating material mixture comprises, in at least one heat cell, a microencapsulated phase change material (PCM).

27. The heat pad of claim 14, wherein a lenticular, semi-convex layer of heat-conducting polymers is present on a skin-facing side of the heat pad in a region of the heat cells.

28. The heat pad of claim 14, wherein the heat pad further comprises a heat display.

29. The heat pad of claim 14, wherein the heat pad further comprises at least one active ingredient on a surface thereof.

30. The heat pad of claim 29, wherein the at least one active ingredient is selected from hyperemizing ingredients and non-steroidal antirheumatics.

31. A heat belt, wherein the heat belt comprises at least one heat pad according to claim 14.

32. The heat belt of claim 31, wherein the heat belt comprises from 2 to 4 heat pads.

33. The heat belt of claim 31, wherein the heat belt is configured to enable joining in the form of a loop, enwrapping a body, by belt elements mounted on a longitudinal axis and ending in a fastener system.

Description

FIGURES

[0083] FIG. 1 shows, by way of example and in schematic form, a target-shaped composed of two concentric rings 2, 3 centered on a point 4 and bridged via the mutually orthogonal connections (lines of the cross) 5, 6.

[0084] FIG. 2 shows, by way of example, a heat pad 7 having one heat cell 8, wherein the heat cell has the shape of four target-shaped units 8, 8, 8 and 8 joined to one another.

[0085] FIG. 3 shows, by way of example, a triangular heat pad 9 having two separate heat cells 10, 11, wherein there is a target-shaped heat cell 11 at the center. A heat cell 10 forms around the central heat cell 11, and is formed from three mutually connected target-shaped heat cell units 10, 10 and 10.

[0086] FIG. 4 shows, by way of example, an elongated rectangular heat pad 12 with two target-shaped heat cells 13, 14.

[0087] FIG. 5 shows, by way of example, a heat cell having two concentric circles in the form of four-leaved clovers connected by four lines that intersect at the center.
