<p>A dashboard for a motor vehicle is prearranged in such a way that the air for ventilation of the passenger compartment of the motor vehicle that exits from a top opening (11) of the dashboard is deviated, by the Coanda effect, along the top surface (1a) of the dashboard and beyond the dashboard in the direction of the occupants of the passenger compartment. The dashboard (1) is moreover provided with at least one flow-perturbing element (13), which can be brought into an active position thereof, in which it projects above the top surface (1a) of the dashboard, in an area immediately downstream of the aforesaid top opening (11), with reference to the direction of the flow of air coming out of the top opening (11). In the active position of the flow-perturbing element, the flow of air coming out of the top opening (11) is deviated towards the windscreen (12) of the motor vehicle. The movement of the flow-perturbing element (13) is governed in synchronism with the movement of an open/close element (18) that controls the flow of air to side front openings (15) provided on the front surface of the dashboard, for the flow of air into the passenger compartment, and to auxiliary side openings (17), provided at the ends of the dashboard, for outflow of air in the direction of the side windows of the motor vehicle. The dashboard is without outlet openings for the air in the main central portion of its front surface, facing the occupants of the passenger compartment.</p> |
