Abstract:
1. A method of forming an inflatable structure in the form of a bulkhead assembly having a tubular member with at least a semi-cylindrical inner surface forming at least first and second compartments separated by a panel interposed therebetween; a flexible connection member comprising a first flexible leg, a second flexible leg extending from the first leg and a third flexible leg extending from the first and second flexible legs, said method comprising the steps of: joining the first and second legs to the semi-cylindrical surface of the tubular member and joining the third leg with an outer periphery of the panel, the first and second legs are joined to the inner surface of the tubular member, while the tubular member is flat and before it is inflated so as to form a tubular shape body, whereas the third leg and the panel are joined together after inflation of the tubular member and formation of the semi-cylindrical inner surface, and forming the bulkhead assembly wherein the first and second legs follow the inner surface of the tubular member so as to have a semi-cylindrical configuration, with the third leg extending substantially normally to a longitudinal axis of the tubular member.
