Definitions

• the present invention refers to a structure for protecting the back, particularly it refers to a back protector for sports use, for example for motorcycle riders.
• back protectors In the sports scope, for example in the practice of skiing, motocross, enduro and motorbike speed competitions, it is known to protect the back wearing protection structures specifically intended for this purpose, usually defined as back protectors.
• the back protectors worn by the user as a technical article of clothing, protect the back, and particularly the spine, in case of fortuitous impacts against the ground or other obstacles, thereby minimizing the risk of being subjected to contusions, perforations by sharpened objects, fractures or other bone damages.
• Generally back protectors consist of a plurality of shaped protective elements, each of which enveloping at least a corresponding portion of the back extending in succession from the cervical vertebrae to the lumbar vertebrae or the coccyx.
• the shaped protective elements are coupled one to another, for example they are fit together, or they are fixed to a supporting vest the user could wear.
• the back protector Independently from the coupling type existing between the shaped elements, usually the back protector is flexible to adapt to the spine curvature of the user.
• a play is defined between the various shaped elements, allowing the relative rotation between the consecutive shaped elements and / or their partial overlapping.
• the shaped elements are mold as curved plates or lamina enveloping at least partially a portion of the user's back at both sides of the spine.
• the shaped elements may all have one or more protruding portions overlapping at least partially on an adjacent shaped element.
• each shaped element is generally solid.
• the shaped elements may be implemented as plates made of a rigid or partially flexible plastic material, or they may have a sandwich structure obtained by overlapping a number of resilient and rigid material layers, having different shock absorbing coefficients.
• the impacts the shaped elements eventually are subjected to, are transmitted partially softened to the user, because part of the collision force is absorbed by the shaped elements themselves, and any way they are divided on a large area of the back; in this way the forces acting on limited portions of the back are minimized. Further the shaped elements form a shield against the penetration of possible injuring objects.
• the back protectors are usually provided with belts allowing the user to wear the back protector as a knapsack.
• the belts usually of the extension adjustable type, are fixed to the first and the last shaped element of the back protector, that is at the upper and lower portions thereof.
• the belts may be fixed also laterally, at the intermediate shaped elements of the back protector.
• the back protectors may comprise the afore described vest.
• a first drawback is because the conventional back protectors usually do not adapt immediately to an occurred change of the user's spine extension. For example, when the user suddenly stretches out the back changing from a sitting position to an upright and bent - forward position, the spine is extended; in this way the upper cervical vertebrae (e.g. the first three cervical vertebrae) and some lumbar vertebrae may be no more protected by the shaped elements of the back protector, with evident risks for the user safety. For example, in motocross some rider movements, standing on the motorbike footboards, entail an increase of the spine length up to the 15% compared to the extension corresponding to the user seating on the motorbike. The rider spine may extend in the afore said way also in case of fall, for example in case wherein the user, banging against the ground, tends to bring the knees to the chest.
• the upper cervical vertebrae e.g. the first three cervical vertebrae
• some lumbar vertebrae may be no more protected by the shaped elements of the back protector,
• Some conventional back protectors provide for the possibility of changing the number of shaped element, but this operation can be done, obviously, only in case of non-use.
• a second drawback of the conventional back protectors is the fact that the shaped elements usually have not a great intrinsic capacity of absorbing shocks. In other words, each shaped elements is not able to deform appreciably for minimizing the impact force transmitted to the user as much as possible.
• a third drawback is because the elements composing the back protector have little breathability. This feature affects negatively on comfort of the user wearing the back protector. The air circulation between the back and the back protector is at minimum or absent, and this is the cause of an intense sweating.
• back protectors are also available in which, alternatively to the plurality of shaped elements, a single flexible element is present, made of a resilient material, e.g. a rubber pad.
• the present invention does not concern this type of back protector.
• the U.S. Patent 4,680,812 describes a back protector comprising a shield made of a foamy material in the inside thereof structural elements hinged one to another are present. Every structural element is contained in the shield, that is configured as single shell (col. 4, lines 9 - 17). In an embodiment (figure 8), the structural elements are constrained one to another by a sliding coupling allowing just the shield bending, but actually it does not allow the longitudinal extension of the back protector, remaining any way defined by the shield, that is the shell made of foamy material, with no possibility of changes.
• the US Application n°. 2010/02631 1 1 describes a solution similar to the previous one, wherein the structural elements are hinged one to another to allow the shield to flex and adapt to the back curvature of the user.
• the shield (reference 54 in the figures), comprising the structural elements in its inside, does not allow these elements to move away one from another, that is it prevents the extension of the back protector.
