Abstract

The cabin exhaust device ventilates vehicles provided with retractable windows and mounts on a portion of the vehicle, preferably on a door frame or in an opening between a window panel and a window frame. The cabin exhaust device comprises a squeegee and a ventilation panel having an air dam, a first portion, and a second portion, wherein the first and second portions are provided with angularly oriented apertures, thereby creating a vacuum on the vehicle'"'"'s interior side. The first and second portions are outwardly convexed, thereby facilitating the creation of a pressure differential between the vehicle'"'"'s interior and its exterior, thus forcing the air and other contaminants out from the vehicle'"'"'s interior.

Claims

1. A cabin exhaust device for ventilating a vehicle, the cabin exhaust device comprising;

a vehicle cabin ventilating panel including an inner surface, an outer surface, a top side removably mountable to a window frame of the vehicle, a first portion having an outwardly convex shape, a second portion having an outwardly convex shape, and a bottom side, wherein the outwardly convex shape of the first portion and the second portion is defined between the top side and the bottom side;

a plurality of apertures disposed in the first portion and the second portion facing outwardly away from the outer surface, the plurality of apertures extending from the outer surface to the inner surface; and

an angled air dam disposed between the first portion and the second portion extending across the vehicle cabin ventilating panel from the bottom side to the top side, wherein an end of the first portion is spaced apart from an end of the second portion at the angled air dam by a predetermined distance wherein the predetermined distance is a function of the height of the angled air dam as measured outwardly from the outer surface of the first portion.

2. The cabin exhaust device of claim 1, wherein the plurality of apertures disposed in the first portion are pointing at an angle towards the angled air dam and wherein the plurality of apertures disposed in the second portion are pointing at an angle away from the angled air dam.

3. The cabin exhaust device of claim 1, wherein the plurality of apertures comprises a plurality of inlets disposed on the inner surface of the vehicle cabin ventilating panel and a plurality of outlets disposed on the outer surface of the vehicle cabin ventilating panel.

4. The cabin exhaust device of claim 1, wherein the plurality of apertures are formed at an angle of 20 degrees to 80 degrees.

5. The cabin exhaust device of claim 1, wherein the first portion and the second portion extend longitudinally along the top side and the bottom side of the vehicle cabin ventilating panel.

6. The cabin exhaust device of claim 1, wherein the angled air dam extends perpendicularly to the top side and the bottom side of the vehicle cabin ventilating panel.

7. The cabin exhaust device of claim 1, further comprising:

a rear panel attached to the inner surface directly behind the first portion and the second portion.

8. The cabin exhaust device of claim 1, further comprising:

a drip shield attached to the bottom side of the vehicle cabin ventilating panel extending along an entire length of the vehicle cabin ventilating panel.

9. The cabin exhaust device of claim 8, further comprising:

a squeegee attached to the inner surface and disposed between the bottom side and the drip shield.

10. A method for ventilating a moving vehicle comprising:

providing a vehicle cabin ventilating panel having a top side, a bottom side, an inner surface, and an outer surface;

providing a first portion having an outwardly convex shape and a second portion having an outwardly convex shape in the vehicle cabin ventilating panel extending longitudinally along the top side and the bottom side, wherein the outwardly convex shape of the first portion and the second portion is defined between the top side and the bottom side;

providing a plurality of apertures in the first portion and the second portion facing outwardly away from vehicle cabin ventilating panel and extending from the outer surface to the inner surface;

providing an angled air dam between the first portion and the second portion extending across the vehicle cabin ventilating panel from the bottom side to the top side, wherein an end of the first portion is spaced apart from an end of the second portion at the angled air dam by a predetermined distance wherein the predetermined distance is a function of the height of the angled air dam as measured outwardly from the outer surface of the first portion; and

mounting the top side of the vehicle cabin ventilating panel to a window frame of the vehicle to direct air flow from an interior of the vehicle to an exterior of the vehicle through the plurality of apertures when the vehicle is in motion.

11. The method of claim 10, wherein providing a vehicle cabin ventilating panel having a top side and a bottom side comprises:

providing a top side extending longitudinally along the window frame of the vehicle;

providing a bottom side extending parallel to the top side.

12. The method of claim 10, wherein providing a plurality of apertures in the first portion and the second portion facing outwardly away from the vehicle cabin ventilating panel comprises:

providing a plurality of apertures pointing at an angle towards the angled air dam in the first portion; and

providing a plurality of apertures pointing at an angle away from the angled air dam in the second portion.

13. The method of claim 10, wherein providing an angled air dam between first portion and the second portion extending across the vehicle cabin ventilating panel from the bottom side to the top side comprises:

providing an angled air dam extending perpendicularly to the top side and the bottom side of the vehicle cabin ventilating panel.

14. The method of claim 10, wherein mounting the top side of the vehicle cabin ventilating panel to a window frame of the vehicle to direct air flow from an interior of the vehicle to an exterior of the vehicle through the plurality of apertures when the vehicle is in motion comprises:

providing a plurality of inlets in the plurality of apertures on an inner surface of the vehicle cabin ventilating panel;

providing a plurality of outlets in the plurality of apertures on an outer surface of the vehicle cabin ventilating panel; and

directing air flow through the plurality of apertures from the plurality of inlets to the plurality of outlets.

15. The method of claim 10, further comprising:

providing a drip shield attached to the bottom side;

providing a squeegee attached to an inner surface of the vehicle cabin ventilating panel and between the bottom side and the drip shield; and

facilitating the creation of a pressure differential between the interior of the vehicle and the exterior of the vehicle when the squeegee meets a top of a window panel of the vehicle.

16. A cabin ventilating device comprising:

a vehicle cabin ventilating panel comprising a top side, a bottom side, and a first portion having an outwardly convex shape and a second portion having an outwardly convex shape extending longitudinally along the top side and the bottom side, wherein the outwardly convex shape of the first portion and the second portion is defined between the top side and the bottom side;

a plurality of apertures disposed in the first portion and the second portion facing outwardly away from the vehicle cabin ventilating panel, the plurality of apertures being defined by a protruding portion extending inwardly from an inner surface of the vehicle cabin ventilating panel; and

an angled air dam disposed between the first portion and the second portion extending across the vehicle cabin ventilating panel perpendicularly to the top side and the bottom side, wherein an end of the first portion is spaced apart from an end of the second portion at the angled air dam by a predetermined distance wherein the predetermined distance is a function of the height of the angled air dam as measured outwardly from an outer surface of the first portion.

17. The cabin ventilating device of claim 16, wherein the plurality of apertures comprises:

a first plurality of apertures disposed in the first portion pointing at an angle towards the angled air dam; and

a second plurality of apertures disposed in the second portion pointing at an angle away from the angled air dam.

18. The cabin ventilating device of claim 16, further comprising:

a rear panel attached to the inner surface of the vehicle cabin ventilating panel directly behind the first portion and the second portion.
