This disclosure relates to a grille for an air extractor that vents air from a passenger compartment of a vehicle to improve air flow within the passenger compartment.
Air extractors are currently provided in the passenger compartment to enhance airflow inside the vehicle. Poor air flow can cause window fogging if moist air is not drawn away from the inner surface of the window glass. Air extractors also vent air from the passenger compartment to reduce the force required to close the doors of the vehicle.
Currently available air extractors include holes or perforations in the package tray (a panel that extends from the top of rear seatback to the lower edge of a rear window). Air extraction holes in the package tray create sight lines from outside the rear window and inside the vehicle to sheet metal and structural components beneath the package tray. To eliminate objectionable sight lines, the holes may be covered by textile covering materials that block the airflow through the air extractors. Blocking air flow through the extractors may exacerbate window fogging problems and increase the effort required to close the doors of the vehicle.
This disclosure is directed to solving the above problems and other problems as summarized below.
An air extractor is disclosed for a package tray including a fixed vane grille that covers air extractor openings in the package tray. The grille has curved vanes that extend transversely across the vehicle. The vanes have an upper edge that is closest to the rear window glass and a lower edge that is forward of the upper edge. The orientation of the vanes is intended to block sight lines from inside and outside the vehicle to the vehicle structure below the package tray. The vanes are also located and oriented to draw heavier moist air away from the rear window glass and out of the passenger compartment.
According to one aspect of this disclosure, an air extractor vent is disclosed for a vehicle having a rear window disposed behind a rear seatback. A package tray extends between the rear seatback and the rear window and defines at least one air extraction opening adjacent the rear window. A grille is assembled over the air extraction opening that includes vanes for directing air passing through the grille and away from the rear window.
According to another aspect of this disclosure, a grille is provided for a package tray that defines an air extraction opening adjacent a rear window of a vehicle. The grille comprises a frame extending around a perimeter of the air extraction opening and a plurality of fixed vanes. The fixed vanes are attached to the frame and extend parallel to the rear window. The vanes obstruct less than 50% of the open area of the air extraction opening.
According to other aspects of this disclosure, the vanes may be curved to more extensively block sight lines through the air extraction opening from outside the vehicle and from inside the vehicle to an area below the package tray. The vanes may have a lower edge and an upper edge disposed rearward relative to the lower edge to draw moist air from a rear edge of the rear window where the rear window meets the package tray.
The above aspects of this disclosure and other aspects will be described in greater detail below with reference to the attached drawings.
The illustrated embodiments are disclosed with reference to the drawings. However, it is to be understood that the disclosed embodiments are intended to be merely examples that may be embodied in various and alternative forms. The figures are not necessarily to scale and some features may be exaggerated or minimized to show details of particular components. The specific structural and functional details disclosed are not to be interpreted as limiting, but as a representative basis for teaching one skilled in the art how to practice the disclosed concepts.

The curved vanes increase the extent to which the grille 20 blocks the line of sight through the opening 38 to body structures 40 that are disposed below the package tray 16. The line of sight from inside the vehicle 10 is indicated by the arrow LSi. The arrow LSo indicates the line of sight from the outside of the vehicle through the rear window 12. The shape and orientation of the curved vanes 36 are more effectively block the lines of sight LSi and LSo compared to the flat vanes 28 shown in
The embodiments described above are specific examples that do not describe all possible forms of the disclosure. The features of the illustrated embodiments may be combined to form further embodiments of the disclosed concepts. The words used in the specification are words of description rather than limitation. The scope of the following claims is broader than the specifically disclosed embodiments and also includes modifications of the illustrated embodiments.
