Abstract
A process for the manufacture of a protecting and immobilizing element of the mattress-like type consists in providing containing means (2, 20) and a layer of flexible material (3, 21) inside them, with the peripheral edges (4, 22) of the flexible layer (3, 21) protruding from the containing means (2, 20). Anchoring means (5) and a first netting structure (6, 23) are also arranged inside the containing means (2, 20) so that the netting structure (6, 23) is in direct contact with the flexible layer (3, 21) and the anchoring means (5) pass through the netting structure at predetermined positions (12, 25). The containing means (2, 20) are then filled with a filling material (7) comprising solid and/or fluid elements, and a second netting structure (8) is superposed on the filling material. Finally, by superposing, at least partially, the peripheral edges (4, 22) of the flexible layer (3, 21), a closed cover is produced from which the ends (11, 27) of the anchoring means (5) protrude.
