Stadium seat stabilization system

A stadium fitting, the stadium fitting comprising:

• a fitting member;
• a support member configured to secure the fitting member to a rail, wherein the rail comprises an upper surface, a front overhang, and a rear overhang;
• wherein the support member comprises a return portion and an intermediate portion;
• wherein, with the support member securing the fitting member to the rail, (i) the return portion engages and wraps at least partially around the rear overhang of the rail and (ii) the intermediate portion extends from the return portion along the upper surface of the rail and at least partially beyond the front overhang;
• wherein the intermediate portion comprises a pocket having an aperture, and wherein, with the support member securing the fitting member to the rail, the aperture communicates with the upper surface of the rail;
• a moveable insert that includes a fastener, wherein the moveable insert, with the support member securing the fitting member to the rail, is received in the pocket and engages the upper surface of the rail;
• and
• wherein, with the support member securing the fitting member to the rail, and with the moveable insert received in the pocket and engaging the upper surface of the rail, advancement or rotation of the fastener translates the moveable insert relative to the pocket, causing the moveable insert to exert an upward force on the support member and a downward force on the rail through the aperture, urging the return portion toward engagement with the rear overhang of the rail and securing the support member against the rail.
