Abstract

Le but de la présente invention est d'améliorer le confort pour les occupants par la suppression d'une augmentation ou d'une baisse excessive de la température de l'air conditionné apporté à chaque sortie dans le cas où de l'air conditionné doit être fourni apporté non seulement aux occupants de siège avant mais également aux occupants de siège arrière. À l'intérieur d'un boîtier (10) est disposée une plaque de déviation (50) qui est pourvue : d'une partie de guidage d'air chaud (51) pour guider l'air chaud s'écoulant à l'extérieur depuis l'extrémité aval d'un passage d'air chaud (31) vers un passage de siège arrière (37) ; et d'une partie de guidage d'air froid (55) pour guider l'air froid s'écoulant à l'extérieur depuis l'extrémité aval d'un passage d'air froid (33) vers un passage de chaleur (36).
