Abstract:
1. A ventilation unit for ventilating the interior of a motor vehicle, the ventilation unit having an inner supply channel and a flow exit control apparatus, the flow exit control apparatus comprising: a first component having an upper surface defining a flow exit plane, and a second component, which can be brought into different displacement conditions relative to the first component, each of the first and second components having closure surfaces, the second component being laterally displaceable with respect to the first component parallel to the flow exit plane to direct air at various exit angles, the second component being vertically displaceable with respect to the first component and the flow exit plane so that separated confronting closure surfaces on the first and second components can all lie on one another to permit complete closure of the flow exit control apparatus to inhibit the exit of air from the ventilation unit by eliminating any air flow between the first and second component, wherein the flow exit control apparatus of the unit is connected to a motor vehicle windscreen, and lateral displacement of the second component to a first position directs an air flow toward the windscreen and lateral displacement of the second component to a second position directs an air flow toward a central interior of the motor vehicle.
