Abstract

L'invention concerne un dispositif de projection (100), destiné à un affichage tête haute, comprenant un boîtier pourvu d'une ouverture destinée au passage d'un faisceau lumineux représentant une image virtuelle. Le dispositif de projection (100) comprend un support de combineur (104) destiné à maintenir une vitre de combineur (106). Le support de combineur (104) peut tourner entre une position de projection, dans laquelle la vitre de combineur (106) projette le faisceau de lumière dans une zone de vision d'un conducteur, et une position fermée dans laquelle la vitre de combineur (106) est abaissée dans le boîtier (1100), disposée dans le boîtier ou peut être disposée dans le boîtier. En outre, le dispositif de projection (100) comporte un moyen de guidage (102) pourvu d'au moins un rail de guidage (108) pour guider un élément de recouvrement (110) destiné à recouvrir l'ouverture du boîtier. L'élément de recouvrement (110) est disposé ou peut être disposé de façon mobile en rotation et/ou en translation dans le rail de guidage (108). Le rail de guidage (108) est conçu pour guider un plan d'extension principal de l'élément de recouvrement (110) sensiblement parallèlement à un plan d'extension principal de la vitre de combineur (106). En outre, le dispositif de projection (100) comprend un mécanisme d'entraînement (112) destiné à synchroniser le mouvement de l'élément de recouvrement (110) avec le mouvement du support de combineur (104). Le mécanisme d'entraînement (112) comporte au moins un premier élément de sortie (118) couplé à l'élément de recouvrement (110), un second élément de sortie (120) couplé au support de combineur (104) et un élément d'entraînement (116) s'engageant dans le premier élément de sortie (118) et dans le second élément de sortie (120).
