US Patent 12109925 Ventilated seat with perforated electroconductive fabric heating elements

The present disclosure provides a climatized seat equipped with a ventilation system and a heating system for use separately or synergistically. The heating system includes electroconductive fabric sections having at least one perforation positioned in surrounding relation to a passageway formed in a seat element, for instance a cushion assembly. Each electroconductive fabric section includes conductors electrically coupled to a controller for activating the electroconductive fabric. The electroconductive fabric can be perforated to accommodate complex shapes, features and transitions associated with the surface to be heated and provides more direct and even heat distribution as compared to conventional resistive wires woven into fabric.
