<p>Apparatus for protecting an occupant of a building from flying debris from a frangible structure such as a window or the like, in the event of an explosion or other blast. The apparatus comprises a protective louver system (10) disposed adjacent the building structure. The louver system (10) comprises a plurality of louvers (12) that are movable from an open position to a closed position wherein they form a protective barrier covering the building structure. A louver closing device (30) is operatively connected to the louvers (12) and is operable to move them to the closed position in the event of an explosion or other blast. The louvers (12) are provided with locking portions (22) so that they are interlocked when in the closed position and displaced inwardly by an explosion or other blast. Reinforcing cables (14) may be positioned adjacent the inner surface of the louver system (10) to support the louvers (12) in the closed position when they are displaced inwardly by the explosion or other blast.</p> |
