Claim:
A shutter system for covering an opening in a wall of a building, the shutter system comprising: a mounting assembly that includes at least one pair of guide tracks, each guide track of the at least one pair being mountable to the building on opposing sides of the opening, each guide track including a plurality of inner surfaces that define a guide channel, two of the inner surfaces opposing one another and at least one of said two, opposing inner surfaces including at least one protruding member that extends into the guide channel and angles away from an open end of the guide channel; and a barrier assembly that includes a plurality of interlocking flexible slats, at least some of the slats defining at least one angled recess constructed to accommodate unobstructed passage of the slats in the guide channel during deployment and retraction of the barrier assembly and further constructed to enable the slats to engage the at least one protruding member of the guide track and thereby retain the slats in the guide channel in the event that the slats are deflected due to exertion of a displacement farce against the barrier assembly.
