Abstract: An apparatus for alleviating window buffeting noise and associated vibrations along a rear window of an automotive vehicle is provided. The apparatus includes a baffle received in a recess of a B-pillar. The B-pillar is located forward of the rear window, and the baffle is disposed vertically along the B-pillar. The baffle extends over at least a portion of the height of the opening to the rear window. An actuation mechanism moves the baffle outward of the B-pillar when the window is lowered to a predetermined lower position, such that the baffle deflects air flow and thus reduces window buffeting along the open window. The actuation mechanism also retracts the baffle back into the B-pillar when the window is raised to a predetermined raised position, at which window buffeting is no longer significant.
