Abstract
A composite heating device for homogeneous heating of surfaces, especially curved surfaces, such as in particular for homogeneous heating of steering wheels, the composite heating device having a heating element and a multipart thermally conductive layer that includes at least two thermally conductive portions with different thermal conductivities, a first portion of the thermally conductive portions being in contact with the heating element. Steering wheel integrating such a composite heating device.
Claims18
A composite heating device for homogeneous heating of a surface, wherein the composite heating device comprises a heating element and a multipart highly thermally conductive layer comprising at least two highly thermally conductive portions with different thermal conductivities, wherein a first portion of said at least two highly thermally conductive portions is in contact with the heating element, and wherein the heating element is small in surface as compared to the multipart highly thermally conductive layer, representing 2 to 40% of the surface of the multipart highly thermally conductive layer.
