A support device (1) is provided for, comprising a support surface (2) suitable to be placed in contact with an object; at least one inflatable device (3), comprising an air chamber (30) suitable to vary its extension depending on the internal pressure thereof, and an inflation valve (31) suitable to permit a variation of the pressure inside the air chamber (30), at least one depressurisation device (4) positioned between the air chamber (30) and the support surface (2) and comprising: - a main casing (40) impermeable to the passage of fluid, flexible and defining a main volume (40a); an inner casing (41) placed inside the main casing (40), permeable to the passage of gas and flexible; filler particles (42) housed in the inner casing (41); a depressurisation valve (43) suitable to form or interrupt a connection for fluid passage between the main volume (40) and the environment external to the main volume (40) and suitable to permit the depressurisation of the main volume (40a) defining a relaxed configuration in which the filler particles (42) are movable inside the inner casing (41); and a compressed configuration in which the filler particles (42) are compacted and substantially define at least one solid body (42a). |
