Title
(EN) ELECTRIC CUSHION HEATER
(FR) COUSSIN CHAUFFANT ELECTRIQUE
Abstract
(EN)
An electric heater (1) intended for heating foam-moulded cushions, for instance for vehicle seats (2) or mattresses. The heater consists of an electric conductor (3), e.g. an insulated or non-insulated metal wire, which is configured into the shape of one or several bands (4) of closely juxtaposed bights, each one of which comprises a loop and an open portion facing away from the associated loop, substantially all open portions being interconnected by means of local interconnections, e.g. by means of glue, plastic welds or seams, whereby one or several bands (4) of coherent patterns are formed, said patterns intended to be positioned in a mould for casting of cushions, such that the heater to an essential extent becomes anchored in the cushion.
(FR)
La présente invention concerne un élément chauffant électrique (1) destiné à réchauffer des cousins moulés en mousse, par exemple, des sièges de véhicules (2) ou des matelas. L'élément chauffant est constitué d'un conducteur électrique (3), tel qu'un fil métallique isolé ou non isolé disposé en une ou plusieurs bandes (4) d'anses jointives. Chacune de ces anses présente une boucle et une partie ouverte opposée au fond de l'anse, toutes les parties ouvertes étant sensiblement interconnectées au moyen d'interconnexions locales, par exemple au moyen de colle, de soudure plastique ou de coutures. Cela permet de réaliser une ou plusieurs bandes (4) à motifs cohérents, lesdits motifs étant conçus pour être disposés dans un moule destiné à couler les coussins de façon que l'élément chauffant soit dans une certaine mesure scellé dans le coussin.
