Abstract

Circuit pour système de condamnation centralisée de véhicule automobile. Il est pourvu d'un dispositif de protection du conducteur du véhicule dans l'éventualité d'une agression perpétrée par une personne déjà présente à l'intérieur du véhicule. Normalement, le système de condamnation devient actif lorsqu'on actionne un interrupteur de portière (5, 6), par exemple au moyen d'une clé ou d'une télécommande (21, 22). Ainsi, le système actionne des dispositifs (14-18) de commande des serrures des portières et du coffre. Cependant, lorsque le système de condamnation centralisée est inactif, le conducteur peut actionner depuis l'intérieur du véhicule lesdits dispositifs (14-18) de commande des serrures. On a prévu un interrupteur de sécurité (4) destiné à lancer cette opération, les dispositifs (15-18) de commande des serrures des portières et du coffre étant ainsi actionnés (verrouillés). Néanmoins, la portière (14) du conducteur peut encore s'ouvrir afin que le conducteur puisse s'échapper, à la suite de quoi la serrure (14) de cette portière est également actionnée. Ainsi, l'agresseur potentiel se retrouve enfermé dans le véhicule. Un dispositif (20) d'immobilisation du moteur et un signal d'alarme (19) sont également actionnés. Des interrupteurs dissimulés (2, 3) permettent de désamorcer le circuit de sécurité.
