Abstract:
1. A system for distribution of air within a passenger compartment of a vehicle, said system comprising: at least one air-outflow louver located at an airflow opening on a surface facing an internal space of the passenger compartment, for supplying within the passenger compartment a flow of air coming from an air-conditioning device; and a first surface of the passenger compartment and a second surface of the passenger compartment, said first surface and said second surface facing the internal space of the passenger compartment, said first surface and said second surface set adjacent to one another and substantially divergent from one another starting from an area between said first surface and said second surface where said at least one outflow louver is located, a flow-perturbing element separate and downstream from said louver and spaced from said louver along said second surface, said flow-perturbing element moveable between an active position in which said element projects from said second surface, and an inactive position in which said element retracts away from said first surface below a side of said second surface closest to said first surface, and wherein a relative arrangement of the outflow louver and of said first surface and said second surface of the passenger compartment, and the profile of said first surface and said second surface of the passenger compartment, are such that: when the perturbing element is in said inactive position, the flow of air at output from the outflow louver tends to adhere to said second surface of the passenger compartment due to the Coanda effect; and when the perturbing element is brought into its active condition, the flow of air detaches from said second surface of the passenger compartment and tends to adhere, and to remain adherent, to said first surface of the passenger compartment due to the Coanda effect.
