Wind deflector with additional joints

The deflector (1) has upper and lower frames (2b, 2a) comprising two sets of props, where a folding joint (8) is arranged in one of the sets of props that is divided into a set of prop portions such that the frames are foldable about a folding axis. A joint (10) is arranged in the other set of props that is divided into another set of prop portions. A rotational axis (11) of the joint extends outside a plane stretched by the frames and a flat material such that the former set of prop portions are rotatable into a stored position around the rotational axis after folded around the folding axis.
