US Patent 10086680 Integrated sunroof drainage conduit

A sunroof drainage conduit integrated into a heating, ventilation and air conditioning duct (HVAC) duct for a vehicle is provided. The duct may include an elongated, hollow body defining an air passage. The drainage conduit may be integrally formed on a surface of the body of the duct, such as an inside surface or an outside surface. The integrated drainage conduit may be routed through the duct's air passage or around the duct's exterior. A first drain tube may connect the sunroof to an inlet of the drainage conduit for directing drainage away from the sunroof's gutter or trough. A second drain tube may connect to an outlet of the drainage conduit for directing drainage from the drainage conduit to ambient.
