DETAILED DESCRIPTION

[0039] With reference to FIGS. 1 and 2, the self-wrapping safety device for the physical restraint of a person according to the present invention, indicated in its entirety with the reference number 1, comprises a main body 10, at least one self-wrapping strip 11 coupled to said main body 10, at least one pair of activation handles 14 coupled to said at least one self-wrapping strip 11 and a plurality of support handles 13 arranged on said main body 10.

[0040] The main body 10 of the device 1 according to the present invention is able to move from a first position to a second position wherein it is arranged wrapped and rolled up on itself or around the person who needs to be immobilized.

[0041] In particular, said main body 10 comprises a first 10.sub.a and a second 10.sub.b end.

[0042] Said first 10.sub.a and second 10.sub.b end are arranged, in said first position, opposite to each other and coplanar, whilst, in said second position, they are wrapped on themselves or on said person.

[0043] As can be seen in FIGS. 1 and 2, in the embodiment described, said main body 10 has a longitudinal development along a plane XY when it is in said first position, whilst it has a substantially cylindrical shape along the Y axis direction, when it is in said second position.

[0044] In particular, said main body 10 moves from said first position to said second position by a wrapping or rolling around the Y axis direction, in the direction indicated by the arrows shown in FIG. 1.

[0045] Said main body 10 comprises a first 10′ and a second 10″ surface, preferably made of a flexible, strong and washable fabric.

[0046] In more detail, said first surface 10′ or inner surface 10′ is preferably made of a bullet-proof fabric, for example a fabric of the Kevlar type, and/or a fabric which protects against sharp weapons.

[0047] Without departing from the protective scope of the present invention, it is also possible for it to have only a central portion of said first surface 10′ made of that bullet-proof fabric so as to protect in particular a respective part of the body of the user of said safety device 1. That allows, among other things, a reduction in the costs of production of said safety device 1.

[0048] Said first surface 10′ is configured to protect the person immobilized from any impacts or scuffles which could cause physical harm to that same person or to the user of said device 1.

[0049] Similarly to said first surface 10′, said second surface 10″, or outer surface 10″, is also preferably made of flexible, strong and washable material.

[0050] Said main body 10 further comprises a first 12.sub.a and a second 12.sub.b fixing elements respectively arranged on said second surface 10″ in correspondence of said first 10.sub.a and second 10.sub.b end of said main body 10.

[0051] Said first 12.sub.a and second 12.sub.b fixing elements, made for example of Velcro bands, are configured to hook to each other when said main body 10 is in said second position.

[0052] That allows said first 10.sub.a and said second 10.sub.b end of said main body 10 to be fixed to each other, preventing the unintentional reopening of said safety device 1.

[0053] As can be seen in particular from FIGS. 1 and 3, said safety device 1 comprises at least one self-wrapping strip 11 of the known type with longitudinal development along the X axis direction.

[0054] Said self-wrapping strip 11 is preferably made of a metallic material or the like.

[0055] Said self-wrapping strip 11 may also be made of flexible plastic alloys.

[0056] Said self-wrapping strip 11 is coupled to said main body 10, and therefore, similarly to said main body 10, it is able to move from said first position to said second position.

[0057] In the embodiment which is the object of the present invention, said self-wrapping strip 11 is inserted within said main body 10, between said first 10′ and second 10″ surface.

[0058] Without departing from the protective scope of the present invention, it is also possible to provide other ways of coupling between said self-wrapping strip 11 and said main body 10.

[0059] For example, said self-wrapping strip 11 may be coupled to said first surface 10′ or to said second surface 10″.

[0060] In particular, said self-wrapping strip 11 comprises a first 11.sub.a and a second 11.sub.b end.

[0061] Said first 11.sub.a and second 11.sub.b end of each self-wrapping strip 11 are arranged, in said first position, opposite to each other and coplanar, whilst, in said second position, they are wrapped on themselves or on said person.

[0062] Said first end 11.sub.a of said self-wrapping strip 11 is arranged in correspondence of said first end 10.sub.a of said main body 10 and said second end 11.sub.b of said self-wrapping strip 11 is arranged in correspondence of said second end 10.sub.b of said main body 10.

[0063] In more detail, in particular with reference to FIGS. 7a and 7b, each self-wrapping strip 11 is able to move from said first position wherein it is convex in the plane XY, relative to the positive Z axis, to said second position wherein it is concave, in the plane XY, relative to the same positive Z axis.

[0064] Indeed, each self-wrapping strip 11, during the movement from said first position to said second position, inverts its concavity and wraps on itself or on the person placed in contact with said main body 10.

[0065] In particular, each self-wrapping strip 11 is able to invert its concavity following a pressure exerted by the body of the person to be immobilized, or following a tensile force exerted from the outside by a user, or following a combination of such stresses.

[0066] In particular with reference to FIG. 1, in the embodiment described, if the person subjected to being immobilized exerts, by means of their body, a pressure on the main body 10, and therefore on said self-wrapping strip 11, along the plane XY and towards the positive Z axis, that force will allow the inversion of concavity and therefore for wrapping of said self-wrapping strip 11 on itself.

[0067] In more detail, that force allows said self-wrapping strip 11 to move from said first position to said second position wherein it is wrapped on itself or on the person, that is to say, to invert its concavity and consequently, said main body 10 will also move from said first position to said second position, forced by the movement in the position of said self-wrapping strip 11.

[0068] As indicated, that safety device 1 comprises at least one pair of activation handles 14.

[0069] Said at least one pair of activation handles 14 is coupled to said at least one self-wrapping strip 11.

[0070] As indicated, if a user exerts a tensile force on said at least one pair of activation handles 14 towards the positive Z axis, said at least one self-wrapping strip 11, being coupled with said at least one pair of activation handles 14, will wrap on itself or on the person placed in contact with said main body 10.

[0071] In more detail, that tensile force exerted on said at least one pair of activation handles 14 allows the self-wrapping strip 11, coupled with said at least one pair of activation handles 14, to move from said first position to said second position wherein it is wrapped on itself or on the person, that is to say, to invert its concavity.

[0072] In particular with reference to FIGS. 4 and 5, each activation handle 14 is fixed to said at least one self-wrapping strip 11 by fixing means 15.

[0073] Said fixing means 15 are for example, screws, bolts, rivets or the like.

[0074] In particular, each activation handle 14 comprises a respective cable 14′, preferably made of steel, provided with a first 14.sub.a and a second 14.sub.b end connected to respective fixing means 15.

[0075] Suitably, that cable 14′ allows an increase in the hold and resistance of said activation handle 14 in the case of stresses, for example tensile or twisting, exerted by a user.

[0076] By way of example, each activation handle 14 is preferably made of woven polymeric threads with turned-up edges to contain said cable 14′ and prevent any physical harm to the user.

[0077] As can be seen from FIG. 5, said fixing means 15 allow the coupling of each activation handle 14 of at least one pair of activation handles 14 with a respective self-wrapping strip 11. In that way, the user is able to activate the safety device 1 when desired.

[0078] In addition, as previously said, the combination of a tensile force exerted by a user on each activation handle 14 and of a pressure exerted by the body of the person who needs to be immobilized on said self-wrapping strip 11, allows wrapping of the self-wrapping strip 11 and therefore of the main body 10 which is faster than in the case of the individual stresses.

[0079] In order to make the safety device 1 more reactive, it is possible to insert a plurality of self-wrapping strips 11 within said main body 10, each provided with a pair of activation handles 14.

[0080] In a further embodiment of the safety device 1, said plurality of self-wrapping strip 11 comprises a first self-wrapping strip 11, or main self-wrapping strip 11, arranged in the central portion of said main body 10 and coupled to said at least one pair of activation handles 14, and at least one second self-wrapping strip 11, or secondary self-wrapping strip 11, arranged parallel to said first self-wrapping strip 11 and having a smaller size than said first self-wrapping strip 11.

[0081] If a user exerts a tensile force on said at least one pair of activation handles 14 towards the positive Z axis, said first self-wrapping strip 11, being coupled with said at least one pair of activation handles 14, is wrapped on itself or on the person placed in contact with said main body 10. Moreover, said at least one second self-wrapping strip 11, having a resistance lower than said first self-wrapping strip 11, wraps on itself or on the person placed in contact with said main body 10, at the same moment wherein wrapping of said first self-wrapping strip 11 occurs, without the use of dedicated activation handles.

[0082] Said device 1 also comprises a plurality of support handles 13.

[0083] Each support handle 13, is integrally fixed with said second surface 10″ of said main body 10.

[0084] Each support handle 13 allows, for example, a user to easily grasp said safety device 1 for transporting it if necessary when it is in the closed position, or for stabilizing and controlling the movements of the person wrapped by that device 1, or the like.

[0085] FIGS. 6a and 6b show a second embodiment of the connection between said activation handle 14 and said self-wrapping strip 11.

[0086] Each activation handle 14 is fixed to said self-wrapping strip 11 by a connection element 14.sub.e.

[0087] In particular, as can be seen from FIGS. 6a and 6b, each activation handle 14 is provided with a first 14.sub.c and a second 14.sub.d pin connected to said connection element 14.sub.e.

[0088] In particular with reference to FIG. 8, in a further embodiment of the present invention, said main body 10 comprises within it a plurality of supporting strips 16, between said first 10′ and second 10″ surface.

[0089] In particular, as can be seen from FIG. 8, each supporting strip 16 has a development along the Y axis direction and is arranged in correspondence of at least one self-wrapping strip 11. In particular, each supporting strip 16 does not interfere with said at least one self-wrapping strip 11.

[0090] In more detail, each supporting strip 16 of said plurality of supporting strips 16 is configured to support, in use, said main body 10. Therefore, each supporting strip 16 is preferably made of rigid material such as, for example, plastic material or the like.
