<p>The windshield device has a frame divided in two sub-frames and another frame divided in other two sub-frames, where the latter frame is pivotally connected with the former frame around a folding axis. The longitudinal sections (13) of the former frame are partially stored above the longitudinal sections (3) of the latter frame, while the cross-sections (14) of the former frame are immerged with an partially inclined or domed contour characteristic in the latter frame such that the axes (7,17) of the pivoting hinges (6,16) of the cross-sections are laid on a common axis.</p> |
