Abstract
An inflatable barrier system for a doorway or other opening comprising a front side envelope of rectangular front elevation and dog bone shaped horizontal plane cross section, inflatable with gas and fillable with a hardening foam, combined with an inflatable back side array of tubular air beams configured with self sealant, both connected to a source of gas for inflating the fabric envelope and the back side array of tubular air beams. The front side envelope is configured for frontal resistance to predetermined levels of push, cut, puncture, flame, chemical, and ballistic attack. The system is used as a method for closing a doorway to such attacks by erecting and inflating the system within the opening such that the edges on either side of the opening are gripped between the lobes of the respective ends of the dog bone profile of the front side envelope.
