1. Apparatus for distributing the flow of air in a motor vehicle air conditioning installation comprising a casing (1) for distribution of the flow, in which distribution means are adapted to direct the flow of air passing into said casing towards three openings which respectively correspond to an outlet for ventilation, an outlet for demisting and an outlet for heating, the demisting opening (8) and the heating opening (12) being disposed on respective sides of the ventilation opening (9), characterised in that the distribution means respectively comprise a first flap (4) and a second flap (6) which are both movable, the first flap (4) being movable between a position of closing the demisting opening (8), in which said flap opens the ventilation opening (9), and a position of closing the last-mentioned opening, in which said flap opens the demisting opening, and the second flap (6) being movable between a position of closing the heating opening (12), in which said flap opens the ventilation opening (9), and a position of closing the ventilation opening (9), in which said second flap opens the heating opening (12), said two flaps (4, 6) never simultaneously closing the ventilation opening (9), said two flaps (4, 6) being adapted each to assume all intermediate positions between their limit positions and thus to provide for distribution of the flow between the two openings (8, 9 and 12, 9 respectively) with which they are respectively associated. |
