Air conditioner system for automotive vehicle

An air conditioner system for automotive vehicles comprising:

• conditioning air passage means defining a conditioning air path which branches into front and rear air paths, which rear air path includes rear vent and rear foot air outlets which open into a vehicular cabin near the back seat for discharging conditioning air into said vehicular cabin in the vicinity of the occupant on the back seat and the front air passage includes front vent and front foot air outlets;
• conditioning air generating means disposed within said conditioning air passage means, said conditioning air generating means including a cooling unit for cooling the air flowing through said conditioning air path and a heating unit for heating the air flowing through said conditioning air path, said cooling and heating units being cooperative for producing conditioning air of a desired temperature;
• a door associated with said rear vent and rear foot air outlets operable between a first position in which said door fully closes said rear vent air outlet and fully opens said rear foot air outlet in a first operation mode of the air conditioner system, a second position in which said door fully opens said rear vent air outlet and fully closes said rear foot air outlet in a second operation mode of the air conditioner system, and a third position in which said door opens said rear vent and rear foot air outlet in a third operation mode of the air conditioner system;
• and
• manually operable switch means for selecting one of said operation modes in an ON position, and controlling said door position as a function of an opening condition of said front vent and said front foot air outlets in an OFF position.
