Abstract: The system for event-induced unfolding and stiffening of textile surface- and body structure for their controllable volume- and shape changeability, is claimed. The textile surface and body structures completely or partially consist of hollow connection structures (2) that are filled with liquid or gaseous media and are present in the form of tube-shaped or tubular structures, or materials in an elongated transcript with hollow-profile cross-section. The textile surface and body structures are enclosed by flexible outer envelopes as contiguous textile-made structures as scrim or fabric. The system for event-induced unfolding and stiffening of textile surface- and body structure for their controllable volume- and shape changeability, is claimed. The textile surface and body structures completely or partially consist of hollow connection structures (2) that are filled with liquid or gaseous media and are present in the form of tube-shaped or tubular structures, or materials in an elongated transcript with hollow-profile cross-section. The textile surface and body structures are enclosed by flexible outer envelopes as contiguous textile-made structures as scrim, fabric, knitted fabric or woven fabric. The flexible outer envelopes completely or partially consist of membrane filter materials. Modular sub-segments having textile characters are assembled and joined together in the textile in a production-wise manner, and are made of different plant materials and pre-products of textile surface and body structures consisting of hollow connection structures. The integrative or adaptive textile sub-segments of products represent as textile system, and redundantly receive an integrative static support or acquisition of static and stabilized functions of specifically gas pressurized chambers under pressure in the case of functional failures such as during damages of pressure sheaths by activated spacer fabrics (1) in a comparably, completely, partially and temporally definable manner. The filling of the individual tubular or tube-shaped connection structures occurs over regulatable valve mechanisms and takes place in a cyclically regulatable flow. The individual hollow connection structures are sectionally, irreversibly/reversibly and pressure- and/or level-adjustably fillable over common regulatable valve mechanisms in a bundled manner. The regulatable and monitorable filling- and regulating mechanisms of the hollow connection structures are present in top layers of the textile surface and body structures. The valve mechanisms are sectionally and separately fed from a centrally fed pressure collecting container over filling lines and/or sectionally reverse-secured pressure accumulator. The valve mechanisms are microelectronically and sensorically controllable, are controlled and regulatable over mechanical pressure-redirecting mechanisms, and are made for filling and/or evacuating the hollow connection structures after the venous valve principle. The textile surface and body structures have zones with different stiffness, which the zones bring the different stiffness in a given spatial form during unfolding. The textile surface and body structures have hollow connection structures, which allow the functional guarantee of the textile surface and body structure system as a redundant backup in the case of failure of structural parts or the alteration or maintenance of static properties and loading capacities and/or shape and/or size of the textile surface and body structure at a desired time point after the activation and inducing of the system in an event-induced and regulatable manner. The reagents for the event-induced unfolding and stiffening of the textile surface- and body structure are deposited in a separate reaction chamber (4). Deposition mechanisms such as single- or multi-stage prefilter mechanisms are arranged in a suction area of the membrane filter materials, where the prefilter mechanisms suppress the penetration of foreign bodies and/or undesired gaseous media, liquid media or media occurred in the form of dusts, and prevent and/or delay a premature clogging and blocking of the membrane filter. The membrane filter materials are fixed to the textile carrier material in the form of coatings, and consist of materials such as aquaporins suited for ultrafiltration and/or desalination. An independent claim is included for a method for event-induced unfolding and stiffening of a textile surface- and body structure.
