Abstract
Un système chauffant pour un coussin chauffant fait appel à des éléments chauffants en un matériau à coefficient de température positif, agencés parallèlement entre un conducteur connecté par un fusible (5) à un pôle d'une source d'alimentation en courant alternatif sans mise à terre et un conducteur connecté par un commutateur à triacs (T1) à un pôle de la source d'alimentation en courant alternatif, avec mise à terre. Ces deux conducteurs ont des extensions constituant des liaisons de sécurité vers un circuit intégré à micro-ordinateur (14). Lorsqu'il se produit une défaillance, telle qu'une rupture dans un conducteur à l'intérieur ou près du système de chauffage, une lampe au néon connectée à l'extension de sécurité du conducteur sans mise à terre s'éteint rapidement, par manque de tension. D'autres pannes sont détectées par l'extension de conducteur avec mise à terre, qui a un diviseur de tension avec mise à terre. Un signal de courant alternatif commande un transistor (Q1) qui est mis sur MARCHE lorsque le transistor (Q1) n'est pas amené sur ARRET à cause d'une panne.
