A covering system for a rear storage space of a vehicle, with two guide rails running parallel and arranged on both sides of the rear storage space, includes a largely dimensionally stable closing surface element which has guide devices on both sides. The guide devices are arranged movably within the guide rails and make it possible for the largely dimensionally stable closing surface element to be movable along the guide rails between a lower and an upper end position.At least one pivoting section of the closing surface element is designed such that it can be pivoted downward at least in the upper end position.
