Abstract
Abstract Heating garment intended for hindering little the wearer''s movements and for uniformly distributing the warmth. Heating elements are placed inside passages made by sewing two fabrics the one with the other along parallel lines. The heating elements are not sewn to the fabrics but are maintained by the sewing lines. The form of the heating elements allows them to stretch.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
147 words
Heating garment, comprising conduits each of which contain at least one heating element adapted to be connected to a source of heating medium, the garment in the zone thereof containing the heating elements being made from a fabric which is extensible at least in one direction and each said heating element being extensible at least over the greater portion of its length, characterized in that each said heating element is loosely disposed within said conduits and is extensible due to the fact that it has a configuration whereby it undulates within each of said conduits in a plane parallel to the fabrics between which it is disposed, the developed length of a portion of the heating element being at least 1.5 times the length of its mean line, and due to the fact that said conduits are formed by the assembly together of two fabrics along lines.
Claim 2
Dependent Claim
147 words
Heating garment, comprising conduits each of which contain at least one heating element adapted to be connected to a source of heating medium, the garment in the zone thereof containing the heating elements being made from a fabric which is extensible at least in one direction and each said heating element being extensible at least over the greater portion of its length, characterized in that each said heating element is loosely disposed within said conduits and is extensible due to the fact that it has a configuration whereby it undulates within each of said conduits in a plane parallel to the fabrics between which it is disposed, the developed length of a portion of the heating element being at least 1.5 times the length of its mean line, and due to the fact that said conduits are formed by the assembly together of two fabrics along lines.
Claim 3
Dependent Claim
38 words
Heating garment according to claim 1, characterized in that the heating elements are maintained only by the two fabrics, by the conduits therein and by the means which connect said heating elements with said source of heating medium.
Claim 4
Dependent Claim
30 words
Heating garment according to claim 1, characterized in that the lines of assembly of said fabrics are resilient due to the nature of the substance serving to assemble said fabrics.
Claim 5
Dependent Claim
17 words
Heating garment according to claim 1, characterized in that there is a single heating element per conduit.
Claim 6
Dependent Claim
26 words
Heating garment according to claim 1, characterized in that the heating elements constitute a plurality of networks, the heating powers of the said networks being different.
Claim 7
Dependent Claim
32 words
Heating garment according to claim 5, characterized in that it comprises distributor means for energizing said heating elements, said distributor means permitting connection of heating elements either in series or in shunt.
Claim 8
Dependent Claim
40 words
Heating garment according to claim 1, characterized in that the heating elements are flexible and comprise an electrical resistance wire, consisting of a plurality of strands surrounded by a water-impermeable layer of a substance which is flexible and electrically insulating.
Claim 9
Dependent Claim
40 words
Heating garment according to claim 7, characterized in that the assembly comprising the resistance wire and the said layer is surrounded by a flexible metallic sheath which is surrounded by a water-impermeable layer of a flexible and electrically insulating substance.
Claim 10
Dependent Claim
20 words
Heating garment according to claim 1, characterized in that some of the portions thereof, are not provided with heating elements.
Claim 11
Dependent Claim
30 words
Heating garment according to claim 1, characterized in that the said fabrics are made from filaments comprising a mixture of substances which, under the action of heat, carbonize without melting.
Claim 12
Dependent Claim
27 words
Heating garment according to claim 1 characterized in that at least one portion of said garment is removable and provided with connections for feeding with heating medium.
Claim 13
Dependent Claim
34 words
Heating garment according to claim 1 wherein said assembly together of said fabrics is by sewing and further wherein the lines of assembly of said fabrics are resilient due to the sewing stitch used.
Claim 14
Dependent Claim
37 words
Heating garment in accordance with claim 1, wherein said heating elements are flexible and comprise an electrical resistance wire consisting of one strand surrounded by a water-impermeable layer of a substance which is flexible and electrically insulating.
