摘要

The device has a peripheral wall (3) forming an air duct, and a set of wings (4) extending according to a direction and movable in rotation around axes (A). Each wing includes a main face (10) extending parallel to the wall in a central position from the wing. The wing includes a line of reliefs (16) projecting from the face, and is distributed on the face. Each relief forms a null angle with an axis of the wing to reduce a space between the face of the wing and the adjacent wing or the peripheral wall in the central position. An independent claim is also included for an instrument panel.
