ALLEVIATING REAR WINDOW NOISE APPARATUS

摘要

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.

主权项

1. An noise alleviating apparatus associated with a door of a motor vehicle for alleviating noise caused in response to movement of a window within a window opening of the door, the noise alleviating apparatus comprising:
a baffle support mounted to a forward vertically-extending pillar section of the door adjacent to the window opening; a baffle supported by the baffle support for movement between a retracted position disposed within the baffle support and a deployed position extending outwardly from the baffle support; and an actuation mechanism connected to the baffle and operable for moving the baffle from its retracted position into its deployed position in response to the window moving from a closed position to a predetermined lowered window position within the window opening, the actuation mechanism further operable for moving the baffle from its deployed position to its retracted position in response to the window moving from an open position to a predetermined raised window position within the window opening.
