Abstract

Dans les mécanismes de blocage de portières ou hayons de véhicules, le blocage de l'axe (13) se fait de sorte que plusieurs éléments sont mobiles et une défaillance de n'importe lequel des différents éléments peut faire que ladite portière ou ledit hayon ne se ferme pas bien. L'invention vise à détecter cette situation par l'inclusion d'un plus grand nombre de capteurs qui se chargent non seulement de contrôler la position dudit axe (13), mais également la position relative d'un premier élément de pêne (12) et d'un second élément de pêne (14), par l'intermédiaire de capteurs (8-8'-8'') associés à des circuits respectifs PCBA (7- 7'-7'') qui sont reliés par l'intermédiaire de circuits flexibles (10) à un PCBA général (9) qui recueille les signaux des trois capteurs et émet un unique signal d'état, qui prévient d'une mauvaise fermeture si tous les éléments contrôlés par les capteurs ne coïncident pas avec la position relative prévue par ceux-ci, tout ceci intégré dans un boîtier formellement approprié pour s'adapter à la configuration du pêne.
