US Patent 9616819 Ditch rail stowable article carrier system and method

A vehicle article carrier is disclosed for use on a vehicle having a roof, where the roof has a pair of parallel extending ditch rails forming elongated recesses in the roof. The vehicle article carrier may incorporate a pair of tracks configured to rest within the ditch rails and to be fixedly secured within the ditch rails. A pair of cross bars may be removably securable to the tracks. Each cross bar may further be configured with a cross sectional shape to rest at least partially within an associated one of the ditch rails when placed in a stowed configuration. Each cross bar may further be securable to the tracks so as to extend perpendicularly between the tracks and above the roof when placed in an operative position.
