The pressure drop in a pressurized cabin, for example, in an aircraft cabin, is delayed following the occurrence of an emergency resulting from a door failure, by a mat which has a low air permeability. Such a mat is mechanically secured to the cabin structure to cover the openings in the cabin or body on the inside thereof, for example, to cover a door opening in flight. The air permeability of these mats is such that a pressure equalization is delayed by a time safe enough for humans, whereby the pressure equalization rate does not exceed approximately 2.4 PSI/sec.
