Abstract

L'invention concerne un dispositif pour le renouvellement de l'air dans l'habitacle d'automobiles lors de l'incidence de taux de CO2 égaux ou supérieurs aux limites préprogrammées avec une augmentation de 400 ppm par rapport à la limite recommandée de 1000 ppm, de manière qu'un capteur (2) enregistre 1000 ppm quand la concentration (3) en CO2 est d'approximativement 600 ppm, et émet un signal sonore ou lumineux (4) soit pour l'automobiliste, afin qu'il actionne le système de ventilation (5) ou ouvre partiellement au moins une des fenêtres (6), soit pour un éventuel occupant pour qu'il actionne l'allumage (8) de l'automobile. Sans intervention humaine, l'actionneur (9) actionne le système de ventilation (5) pendant 5 minutes tout au plus et le mécanisme d'ouverture des fenêtres (6), au cas où la ventilation (5) n'est pas suffisante et que persiste la concentration en CO2, il actionne le déverrouillage des portes (10).
