Abstract
L'invention concerne un dispositif de détection des Vibrations comprenant un organe électriquement conducteur normalement supporté sur un siège, comprenant au moins deux éléments espacés formant des contacts électriques. Selon l'invention, le siège comprend deux plaques électriquement conductrices et espacées 1, ayant chacune une voie annulaire 2 formée d'un trou 3 symétrique autour de son axe central; l'organe électriquement conducteur est une barre allongée 4 de section transversale symétrique, montée entre les plaques 1 sur les voies annulaires 2; l'aire en section transversale de la barre 4 par rapport à celle du trou 3 est telle qu'elle permette le mouvement de la barre 4 au loin de la voie 2 lors de Vibrations du dispositif. L'invention s'applique notamment aux équipements de sûreté et de sécurité.
