  • Motor vehicle sunroof with reduced buffeting noise
    Patent number: 6244654
    Abstract: The invention relates to a sliding roof for motor vehicles with reduced sliding roof buffeting noise. It comprises a sliding roof opening, as well as a movable sliding cover (7) for covering the sliding roof opening, whereby, depending on the actual position of the sliding cover (7), a resulting clear sliding roof opening (3) is formed. Pursuant to the invention, the geometry of sliding roofs with an essentially rectangular or trapezoidal, resulting clear sliding roof opening is modified due to the partial or complete covering (5) of at least one of the, as seen in the driving direction, rear corner regions of the resulting clear sliding roof opening (3).
