Abstract: A wind deflector for shielding the occupants of a convertible vehicle from backdraughts, has a rigid board mounted on a substantially flat surface behind the seats of the vehicle, the board being mounted on the flat surface by means of a linkage mechanism by which it may be moved between a retracted position, in which it lies flat against the flat surface, to an operative position in which it extends upwardly behind the seats to a height sufficient to shield the occupants of the vehicle from backdraughts, the lower edge of the rigid board being spaced above the flat surface when the rigid board is in its operative position and an extension of the deflector being attached to the rigid board and the flat surface, to fill the gap therebetween.
