A ROOF RAIL SYSTEM FOR BEING ARRANGED ON THE ROOF OF A VEHICLE AND A METHOD FOR MOUNTING THE ROOF RAIL SYSTEM

A roof rail system for a vehicle includes first and second roof rails each having front and back attachment structures and a rail bar. The first rail bar is attached to its front attachment structure via a first hinge and its back attachment structure via a first lock. The second rail bar is attached to its back attachment structure via a second hinge and its front attachment structure via a second lock. A length of the first rail bar is equal to a first separating distance between the first hinge and the second lock and a length of the second rail bar is equal to a second separating distance between the second hinge and the first lock. The hinges rotate the rail bars in a horizontal plane to attach to the front attachment structures and to rotate the rail bars 90 degrees around length axes of the rail bars, respectively.
