An apparatus for reducing buffeting in a vehicle caused by airflow over a removable or retractable roof-opening includes a rail that is mounted adjacently to the leading edge of the roof-opening. Attached to the rail is an angled deflector that diverts the airflow away from the roof-opening. Extending from the top edge of the deflector is a trip segment that causes the airflow to stabilize and reattach at a point beyond the roof-opening of the vehicle.

Air deflecting apparatus for a motor vehicle

A flexible top for a motor vehicle is provided. The flexible top includes an outer surface, an inner surface, a plurality of air cells coupled between the inner and outer surfaces along the length of the flexible top and a plurality of air inlet ports coupled to the plurality of longitudinal air cells. Operation of the vehicle above a predetermined speed causes air to be forced over an air scoop device which directs a portion of the air over the outer surface as well and another portion of the air into the plurality of air inlet ports. Air flowing into the plurality of air inlet ports flows and into the plurality of longitudinal air cells, inflating and pressurizing the plurality of air cells and tending to separate the outer and inner surfaces to provide the flexible top with increased rigidity. When inflated, the plurality of air cells provide the outer surface with an air foil-like longitudinal cross-section that further enhances the resistance of the flexible top to vibration and flapping.
