Shading device

A shading device, comprising:

• guides that run horizontally or at an inclination of at most 30° to a horizontal;
• a lead bar that is slidably guided in the guides;
• a cloth that can be spread out in a cloth plane and is connected to the lead bar;
• and
• at least one blocking device attached to the guides, the at least one blocking device having a displaceable stop part, a displaceably mounted switching part and a transmission device,
• wherein the stop part is displaceable between a stop position, in which the stop part is brought into contact with the lead bar, and a release position,
• wherein the at least one blocking device is arranged below the cloth plane and below the lead bar,
• wherein the switching part is displaced a displacement movement when contacted by the lead bar,
• wherein the transmission device is connected between the switching part and the stop part, such that when the displacement movement of the switching part acts on the transmission device, the transmission device displaces the stop part between the stop position and the release position, and
• wherein prior to being contacted by the lead bar, the switching part is in a starting position and while the stop part is in the stop position, the switching part is in the starting position.
