Abstract

L'invention porte sur un dispositif antivol pour automobile, comprenant une attache et un module d'avertissement. L'attache est montée sur le pare-brise d'une automobile et sollicite différentes positions dans la surface de la vitre par une force élastique de l'attache. Lorsque la vitre est rompue, l'attache rompt une région de la vitre pour détecter la rupture. Le module d'avertissement est disposé sur l'attache et est actionné pour délivrer en sortie une alarme sonore lorsque l'attache rompt la région de la vitre.
