Wind deflector for convertible vehicle

The wind deflector is provided by an air guidance element (10) which is moved between a lowered stowed position and a raised working position, in which it extends across the heads of passengers in the front passenger seats (3), at the rear of the latter, for lifting the air flow (L) passing over the top of the front windscreen over the heads of the passengers in the rear passenger seats (4). The air guidance element has an aerodynamic profile.
