Abstract

Le dispositif de sécurité selon l'invention comprend un réseau électrique en nappe (1) connecté électriquement à un dispositif électronique de contrôle (2) qui produit un signal de sortie en cas de défaut du réseau électrique en nappe (1). Le réseau électrique est formé de deux fils électriques élémentaires (4, 5), isolés l'un de l'autre par un moyen isolant et assemblés l'un avec l'autre en un fil composite (6) lui-même gainé. Le fil composite (6) est par exemple agencé selon une disposition en allers-retours à brins parallèles de type tissage sur des fils ou bandes de chaîne (7), avec des interstices intermédiaires élémentaires (8) de petite taille. Le dispositif électronique de contrôle (2) détecte la rupture de l'un au moins des fils électriques élémentaires (4, 5) et/ou la mise en contact mutuel d'au moins deux des fils électriques élémentaires (4, 5) l'un avec l'autre, et produit alors le signal de sortie sur la sortie (3).Un tel dispositif de sécurité est particulièrement fiable, et est particulièrement difficile à inhiber ou neutraliser.The safety device according to the invention comprises an electrical tablecloth network (1) electrically connected to an electronic control device (2) which produces an output signal in the event of a fault in the electrical tablecloth network (1). The electrical network is formed of two elementary electrical wires (4, 5), insulated from each other by an insulating means and assembled with each other in a composite wire (6) which is itself sheathed. The composite yarn (6) is for example arranged in a back and forth arrangement with parallel strands of the weaving type on son or warp bands (7), with elementary intermediate interstices (8) of small size. The electronic control device (2) detects the breaking of at least one of the elementary electric wires (4, 5) and / or the mutual contact of at least two of the elementary electric wires (4, 5). with each other, and then produces the output signal on the output (3). Such a safety device is particularly reliable, and is particularly difficult to inhibit or neutralize.
