Abstract

L'invention concerne un circuit de chauffage. Le circuit est caractérisé en ce qu'il comprend des bornes d'entrée 9, 10, un conducteur de chauffage 2 et un fusible thermique 8 branchés en série entre les bornes 9, 10, un fil détecteur 3 de même longueur que le conducteur de chauffage 2 et comportant deux conducteurs 5, 6, séparés par un moyen thermosensible 7 ainsi qu'une résistance 11 branchée en série avec l'impédance du moyen thermosensible 7 et couplée thermiquement avec le fusible 8. Application à des couvertures et coussins électriques chauffants.
