<p>A shock-absorbing device (1) comprising an outer container (2) which is flexible and impermeable to air, defining a primary outer volume (2a); a primary inner container (3) which is permeable to air, housed in the outer container (2), defining a primary inner volume (3c) and comprising a plurality of secondary inner containers (3d) which are permeable to air, defining secondary inner volumes (3a); a plurality of filling particles (4) housed in the secondary inner volumes (3a); at least one valve (5) arranged on said outer container (2) and suitable to make or interrupt an air-passage connection between the primary outer volume (2a) and the external environment and suitable to permit the depressurization of the primary volume (2a), so as to define a released configuration, in which the filling particles (4) are movable inside the inner containers (3a), and a compressed configuration in which the primary volume (2a) is depressurized and the distinct particles (4) are compacted; and in which each of the secondary inner volumes (3a) comprises filling particles (4) of a same type and in which at least two different secondary inner volumes (3a) are provided with filling particles (4) of different types.</p> |
