Abstract: A barrier assembly for mounting to the end of a folding bleacher assembly for blocking access to the area under the bleacher seats. The folding barrier panel may be constructed of a heavy-gauge fabric material. The rearward edge of the panel is attached to a stationary connection at the rearward end of the bleacher assembly, and the forward edge of the panel is attached to a moving connection at the forwardmost seat section, so that the panel is pulled out straight when the bleacher assembly is extended. A chain or cable along the lower edge of the panel member is also stretched out straight between the two connections, so as to prevent persons from lifting the lower edge of the panel and passing thereunder. The upper edge of the panel may be attached directly to the rearward edges of the stacked deck sections, or it may be suspended from the deck sections on a series of pendant chains.
