Vehicle air duct including strength rib
View Patent ↗A vehicle air duct includes a plurality of walls that are connected and define an interior air space. The plurality of walls includes inner and outer surfaces. The air duct extends from a first end to a second end where the first end includes a connection opening. At least one of the plurality of walls includes at least one rib in a region corresponding to the connection opening. The rib extends outward from the outer surface of the at least one wall for maintaining the shape of the vehicle air duct.
1. A vehicle air duct comprising:
a plurality of walls connected and defining an enclosed interior air space, the plurality of walls including inner and outer surfaces, the vehicle air duct extending from a first end to a second end, the first end including a connection opening; and
wherein at least one of the plurality of walls includes at least one rib formed thereon in a region corresponding to the connection opening, the rib extending outward from the outer surface of the at least one wall, the at least one rib further defining the interior air space allowing transport of air and maintaining the shape of the vehicle air duct, wherein the at least one rib includes a pair of outwardly extending side walls extending from the outer surface of the air duct and joined by a top wall wherein the top wall of the at least one rib includes a planar top surface supporting a mating surface above the air duct and wherein the pair of outwardly extending sidewalls and top wall extend longitudinally relative to the air duct.
2. The vehicle air duct of claim 1 wherein the plurality of walls includes a top wall, bottom wall and side walls connected to each other.
3. The vehicle air duct of claim 1 wherein the first end of the air duct includes an arcuate shape proximate the connection opening.
4. The vehicle air duct of claim 1 wherein the at least one rib comprises a plurality of spaced ribs formed thereon.
5. The vehicle air duct of claim 4 including three ribs formed thereon.
6. The vehicle air duct of claim 1 wherein the connection opening includes a flared surface formed thereon that extends outward from the opening.
7. The vehicle air duct of claim 1 wherein the side walls of the ribs include a radius formed at a connection with the top surface of the air duct and at a connection with the top surface of the rib.
8. The vehicle air duct of claim 1 wherein the connection opening has a width exceeding a height of the opening.
9. A vehicle air duct comprising:
a plurality of walls connected and defining an enclosed interior air space, the plurality of walls including inner and outer surfaces, the vehicle air duct extending from a first end to a second end, the first end having an arcuate shape terminating at a connection opening; and
wherein at least one of the plurality of walls includes a plurality of ribs formed thereon in a region corresponding to the connection opening, the ribs extending outward from the outer surface of the at least one wall, the plurality of ribs further defining the interior air space allowing transport of air and maintaining the shape of the vehicle air duct wherein the ribs include a pair of outwardly extending side walls extending from the outer surface of the air duct and joined by a top wall wherein the top wall of the ribs include a planar top surface supporting a mating surface above the air duct and wherein the pair of outwardly extending sidewalls and top wall extend longitudinally relative to the air duct.
