WIND DEFLECTOR DEVICE ON A CLOSABLE ROOF CUTOUT OF A MOTOR VEHICLE

A wind deflector device of this kind having a wind deflector bracket on which a flexible wind deflector structure is held, and which has at least one lateral wind deflector arm which can be displaced by means of a guide mechanism in the vertical direction and in the longitudinal direction of the openable roof section between a lower rest position and an upwardly extended functional position, wherein the guide mechanism has a linear positive guide with a curved guide track along which the wind deflector arm can be displaced relative to the roof section in the longitudinal and vertical directions, is known. According to the invention, at least one additional support surface is assigned to the wind deflector arm, which is supported on a stationary sliding surface running parallel to the guide track. Application in passenger motor vehicles.
