Abstract
Abstract Air inlet for a vehicle dash-panel of the type whereby the air supply opening is screened off. For directing the air flowing through the said opening, the inlet is provided with a number of deflecting vanes, arranged side by side and designed to divert the air flow parallel with a first plane perpendicular to the said vanes, and a pair of deflecting surfaces designed to divert the air flow parallel with a second plane perpendicular to the said first plane, and supporting the said vanes hinged perpendicularly to respective front edges coplanar with the said opening and adjacent to the said screen.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
262 words
An air inlet for a vehicle dash panel comprising: an air duct having a substantially rectangular cross section defined by a first pair of spaced parallel side walls and a second pair of spaced parallel top and bottom walls whose ends are integral with the top and bottom respectively of said first pair of spaced parallel side walls; a plurality of movable vertical vanes arranged side by side for diverting air flow in a horizontal direction, said vertical vanes being rotatable about their vertical axis fixed with respect to said second pair of spaced parallel top and bottom walls; a first means for simultaneously moving said vertical vanes in a horizontal direction, said first means for moving being manually accessible from the exterior of said air duct on the front face of said dash panel; a pair of movable horizontal vanes one each located near each wall of said second pair of spaced parallel top and bottom walls respectively, said horizontal vanes being rotatable about their horizontal axis fixed with respect to said first pair of spaced parallel side walls; a second means for simultaneously moving said pair of horizontal vanes in a vertical direction, said second means for moving being manually accessible from the exterior of said air duct on the front face of said dash panel; and a screen for covering said air duct and both said vertical and horizontal vanes which does not impede access to both of said first and second means for moving while allowing air to flow through said air duct and into the vehicle interior.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
76 words
The device of claim 1, wherein said pair of movable horizontal vanes further comprises first and second hinge means proximate said vane's front and rear edges respectively, said first and second hinge means of each of said horizontal vanes being connected to first and second straight guide members respectively, said first and second straight guide members being capable of cooperating with said second means for moving to enable air to be directed in a vertical direction.
