<p>The process of making of three-dimensional bodies and shapes, substantially hollow, whose deformability and elasticity is controllable as a function of quantity and quality of at least a fluid present in at least one of its internal hollows, includes the provision of a sealed outer bag (1, 1') of substantially laminar material which is provided with an inlet as well as the provision of interwall connections (30, 30'), whereby to permit a limited expansion thereof and such that all over a wide range of pressures inside the bag (1, 1') the body expansion do not go beyond those foreseen or permitted. The covering or sealed bag of substantially laminar material is naturally provided by the skin resulting about a body of foamed resin being molded. The quantity and quality of at least a fluid (5) present in at least one of its internal hollows is controlled by at least an inlet and/or outlet valve (2) connectable to a fluid supplying device such as a pumping system.</p> |
