SHEET HEATING ELEMENT AND SEAT INCORPORATING SAID ELEMENT Russian patent published in 2010 - IPC H05B3/34 

FIELD: heating.

SUBSTANCE: invention relates to thin sheet heating element. Proposed element comprises electro insulating substrate, pair of electrodes, polymer resistor connected with electrodes and including resin composition, gross-linked by one oxygen and nitrogen atoms, at least, one fiber conductor and flake conductor mixed with aforesaid resin composition. The said resin composition represents a product of reaction between reactive resin and reaction resin. Reaction resin features positive temperature coefficient. Fiber conductor comprises either conducting ceramic hairs, or conducting ceramic fibers, or metal fibers, or insulating ceramic hairs, or insulating ceramic fibers, or carbon fibers, or carbon nanotubes and fiber conducting polymer. Proposed seat comprises above described heating element. Substrate can be arranged on either seat or back surfaces.

EFFECT: higher flexibility and lower costs.
