Roof assembly windshield defogging system

摘要

A vehicle roof assembly is coupled to a windshield. The roof assembly includes an outer roof member and an inner roof member which form a duct for conducting conditioned air therethrough. A body panel includes a front panel and a bottom panel which are integrally joined together at a corner. The corner has a plurality of apertures formed therein. An adhesive strip attaches an upper edge of the windshield to the front panel. The apertures receive conditioned air from the duct and form an airflow boundary layer which flows over an inner surface of the windshield. This assembly forms a windshield defogging system.
