A bomb blast drapery is defined by a sheet of substantially resilient fabric having high burst strength and substantial fullness in width and length such as to project peripherally beyond a glass window in a wall opening of an associated building. The fabric sheet has a fullness in a width direction approximately 21/2 times the wall opening width and a length fullness ranging from 20" for a window height of approximately 10" up to approximately 380" for a window height of up to 190". The burst strength of the fabric sheet is approximately 110 lbs. and the weight thereof is substantially 4.2 oz. per linear yard. A bottom hem of the flexible sheet includes a weight and the hem further includes a multiplicity of overfolds housed in a trough. The strength of the fabric sheet, its width and vertical fullness and the weighted bottom hem essentially prevent debris, such as glass shards, created by a bomb blast from adversely effecting humans and property adjacent a window with which the bomb blast drapery is associated.

[ I claim:] [1.] Bomb blast drapery comprising a sheet of substantially resilient fabric having relatively high burst strength and substantial fullness in width and length such as to project peripherally beyond a glass window in a wall opening with which the drapery is adapted to be associated, means for securing an upper edge portion of said fabric sheet to a wall with which the glass window is associated, said drapery including a multi-folded lower end portion having a terminal end portion, and weight means at said terminal end portion for imparting motion resistance to said fabric sheet when the latter is subject to the force of a bomb blast during and after unfolding of said multi-folded lower end portion.
