Problems solved by technology

However, since the longitudinal and transverse bars are spaced apart from the roof, the longitudinal and transverse bars interfere and disturb the airflow over the roof, thereby increasing the drag acting on the vehicle and reducing the vehicle's fuel efficiency

Embodiment Construction

[0012] Referring to the drawings, wherein like numerals refer to like parts throughout the several views, the vehicle is shown generally at 20 . refer to Figures 1 to 3 , the vehicle 20 may include any type and / or size of vehicle 20 including, but not limited to, a passenger car, a sport utility vehicle, or a van.

[0013] The vehicle 20 includes a body 22 . The body 22 extends along a longitudinal axis 24 and includes a first end 26 and a second end 28 at opposite ends of the vehicle 20 along the longitudinal axis 24 . As shown, the first end 26 is the front end of the vehicle 20 and the second end 28 is the rear end of the vehicle 20 . However, it should be appreciated that the relative positions of the first end 26 and the second end 28 may be reversed.

[0014] The body 22 defines a roof 30 . The roof 30 may include the uppermost portion of the body 22 . However, the roof 30 should be construed to include any generally horizontal portion of the vehicle 20 . The roof...

Abstract

A rack system for a roof of a vehicle includes a pair of longitudinal bars extending along a longitudinal axis of the vehicle, and a pair of transverse bars attached to the longitudinal bars and extending across the vehicle. A plurality of riser assemblies pivotably interconnects the longitudinal bars to the roof, to raise and lower both the longitudinal bars and the transverse bars between a deployed position and a stowed position. When in the stowed position, the longitudinal bars and the transverse bars are flush with an exterior surface of the roof. When in the deployed position, the longitudinal bars and the transverse bars are spaced from the exterior surface of the roof.

Description

technical field [0001] The present invention relates generally to vehicles, and more particularly to a vehicle having a roof rack system located on the exterior surface of the roof. Background technique [0002] Many vehicles include a roof rack system that is disposed on the outer surface of the roof. Roof rack systems may be used to secure items (eg, luggage, bicycles, rowboats, etc.) to the roof of the vehicle. Roof rack systems typically include a pair of longitudinally extending rods fixedly attached to the roof, and a pair of transverse rods attached to and extending between the longitudinal rods. [0003] The longitudinal and transverse rods of the roof rack system are spaced from the outer surface of the roof to provide space for tying items to the longitudinal and transverse rods. However, because the longitudinal and transverse rods are spaced from the roof, the longitudinal and transverse rods interfere and disturb the airflow on the roof, thereby increasing dra...
