Abstract

An inflatable packing element (10) for an inflatable packer or bridge plug utilized in subterranean wells comprises a tubular elastomeric sleeve (30) which is surrounded by a plurality of circumferentially overlapping flexible metal ribs (12). The opposite ends of the ribs (12) are respectively welded to an external surface provided on a force transmitting sleeve (14). The sleeve (14) is provided with a shoulder (14a) having an abutting relationship with an internally projecting shoulder (20a) provided on the tubular mounting structure (20) for the inflatable element (10). <IMAGE>
