Retractable cross rail for vehicle roof rack

Image Number 2 for United States Patent #7422130.

A vehicular roof rack system has a cross bar that employs a base member, a top member that is retractable to a position within the base member, a spring for biasing the top member away from the base member, and a spring case encompassing the spring to limit spring extension and thus protraction of the top member. The spring case is a two-piece case within which the spring biases against the base member when the top member is in its stowed position to place the top member in its protracted position. The top member and the base member fit together in the retracted position to form an aerodynamic part to permit the cross bar to reduce drag and wind noise when moved through a medium. When protracted, the top member and the bottom member define a gap therebetween so that cargo to be secured can be tied to the top member.
