Safety installation for stadiums or performance halls

摘要

The installation is intended for stadiums or performance halls comprising terraces. It consists of bracelets (1, 2, 3) attached to the terraces and distributed over the terraces with a number equal to the number of spectators allowed in and intended to be voluntarily placed around the wrist by the spectators. They enable the occupation of the terraces to be controlled and may be lockable from a central unit. IMAGE
