Shading device for a window of an automotive vehicle

A shading device for a window of an automotive vehicle, comprising a shading structure which is displaceable in vehicle-fixed lateral guiding rails between a lowered rest position and a deployed shading position using a drive, the shading structure in the rest position being lowered down in a vehicle-fixed chamber through a passage, the passage being closable by a cover which is movable between an open position and a closed position, the shading device further including a control arrangement for opening and closing the cover and being coupled to a displacement move of the shading structure, the control arrangement comprising a control plunger engaging on the cover, which control plunger is articulated to the cover in opposed pull and push directions, the control plunger being in operative connection with the cover via a spiral tension spring which is spring-elastically tensioned in one movement direction and inactively relaxed in an opposite movement direction, the spiral tension spring including at least one terminal spring winding acting as a tensioning member in the pull direction, all spring windings of the spiral tension spring being compressed to block in the push direction, the spiral tension spring being flanked on an exterior side or on an interior side by a supporting body to clamp the spring windings in a force-fitting manner.
