摘要

The groundsheet (1) has a sail (3) and a raised edge that is attached to an edge of the sail. A groundsheet flap (11) is attached to a part of the edge of the sail, where the flap length, which is perpendicular to the edge of the sail, is greater than the height of the raised edge. The sail is essentially rectangular, where the sail on one side of the rectangle is free of edges, and the flange is formed by an inflatable band (5).
