Vehicle interior assemblies having electrically conductive coating layer(s) within the A-surface of their covers
A vehicle interior assembly, such as a vehicle seat or a steering wheel, includes a cover assembly covering a frame. The cover assembly includes a vinyl or non-woven textile cover and an electrically conductive coating layer (“ECCL”) within an A-surface of the cover. The ECCL may function as a heater, a capacitive touch control, or lighting. Another cover assembly includes first and second ECCLs within an A-surface of a cover. The first ECCL functions as a heater and the second ECL functions as a capacitive touch control. Another cover assembly includes an ECCL and a Positive Temperature Coefficient (PTC) coating layer within an A-surface of a cover. The ECCL functions as a heater dependent on current received from a power source via the PTC coating layer. The PTC coating layer regulates the current received by the ECCL from the power source dependent on a temperature of the PTC coating layer.
