HOLLOW VANE WITH STRUCTURE

摘要

A hollow vane structure for an active grille system 100 having a first piece 12 of the vane body 10 that includes a front side 14 and a back side 16. The first piece 12 has a concave cross-section extending from the front side 14 toward the back side 16. This concave section creates a hollowed inward section 18 on the back side 16 of the first piece 12. The first piece 12 also includes an edge surface 20 formed on the first piece which defines a perimeter of the hollowed inward section 18. A second piece 22 of the vane body is connected to the back side 16 of the first piece 12 and extends across the hollowed inward section 18 and is connected to the first piece 12 to at least the edge surface 20 on the back side 16 of the first piece 12.
