Embodiment Construction

[0023] Provides fabric heating elements that can be embedded in materials that require heat (eg, vehicle seats, clothing, etc.) and are compatible with the material to be heated, thereby providing heat from the inside, which is more efficient than supplying heat from the outside of the material and faster.

[0024] In one example, the device includes a non-metallic porous or perforated fabric heating element comprising an electrically conductive inner discontinuous fibrous mesh layer with integrated conductive busbar strips. The inner layer is joined and sandwiched between two outer insulating layers of woven or nonwoven material (eg, continuous fiber material). Fabric heating elements are configured for use as heated fabrics or embedded in laminates or solid materials. In some embodiments, such as those in which the inner layer is perforated, the resulting structure may include an adhesive between the inner and outer layers and extending through the perforations in the inner...

Abstract

A fabric heating element including an electrically conductive, non-woven fiber layer having a plurality of conductive fibers collectively having an average length of less than 12mm. The fabric heating element also including at least two conductive strips electrically connected to the fiber layer over a predetermined length, positioned adjacent opposite ends of the fiber layer, and configured to be electrically connected to a power source.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to US Provisional Application No. 62 / 102,169, filed January 12, 2015. The contents of US Provisional Application No. 62 / 102,169 are incorporated herein by reference. technical field [0003] The present invention relates to fabric heating elements and methods for making fabric heating elements. SUMMARY OF THE INVENTION [0004] One embodiment includes a fabric heating element comprising a layer of conductive nonwoven fibers having a plurality of conductive fibers, wherein the plurality of conductive fibers collectively have an average length of less than 12 mm. The fabric heating element also includes at least two conductive strips electrically connected to the fibrous layer across a predetermined length, positioned adjacent opposite ends of the fibrous layer, and configured to be electrically connected to a power source. [0005] In one embodiment, the fabric heating element further c...
