Abstract

Dispositif permettant de faire apparaître l'indication du risque de verglas directement sur la surface du pare-brise, face au conducteur ou éventuellement sur une partie de la surface du rétroviseur extérieur. Il est composé d'un film multiple emprisonnant des cristaux liquides, collé sur le pare-brise ou le rétroviseur extérieur et permettant la visualisation instantanée d'une température inférieure à la limite de formation du verglas, c'est-à-dire environ + 1 degrés suivant une figure symbolique quelconque, par exemple la lettre V pour verglas. L'invention peut être utilisée pour tous les véhicules dont la conduite est rendue dangereuse par la présence de verglas.
