    [0001] The present invention relates to the technical field of body protection and more particularly the technical field of absorption structures and / or dissipation of mechanical shocks, that of body protectors and that of protective clothing.
    [0002] The term "body protector" is generally understood to mean an arrangement of materials that absorb and / or dissipate the energy generated during an impact in order to provide some protection to the part of the body facing the protection under normal conditions. use. This absorbing and / or energy dissipating material may or may not be structured.
    [0003] Such body protectors are generally incorporated in protective clothing worn during the exercise of a given activity, and particularly in areas of the body that should be protected against mechanical shocks. Examples of these areas are the shoulders, elbows, forearms, hips, knees, upper shins, mid-shins, lower shins, entire shin, back or head. Examples of such body protectors are presented in the standards EN1621-1: 2013 and EN1621-2: 2014 relating to protective clothing against mechanical shocks for motorcyclists. These body protectors must generally be made of a material that can absorb and / or dissipate the forces generated during a mechanical shock. However, other criteria must also be considered in order to provide comfortable body protectors. Thus, the body protectors should be flexible so as to be able to adapt to the shape of the part of the body to be protected, in particular the joints, that they allow the movement of the wearer, whether light, and that they be breathable. A more particular example is shown, for example, in EP 2399470. The protection element described in this document comprises a base and protuberances, each of the protuberances extending from and normally to the base. The protuberances also have a through hole. Each of the protuberances is either a solid of revolution about a central axis (that is to say that the outer wall and the inner wall of the protuberances are straight cylinders with a circular base), or a solid with rotational symmetry of order 6 with regular hexagonal base.
    [0004] The base here is non-ventilated, that is to say that outside the orifices passing through the protuberances, there are no other orifices present in the material. Due to the presence of through holes, the protective element and the body protector have a certain degree of breathability, but it would be interesting to be able to make the material even more breathable while maintaining the impact resistance properties. Another solution would be to make elastomeric nets, but according to current knowledge, such nets do not have sufficient impact resistance in the conditions dictated by the standards, including those mentioned above.
    [0005] Thus, the need for a protective element that absorbs and / or dissipates mechanical shocks is always present. Such a protective element should preferably be both sufficiently absorbent and / or dissipative, sufficiently breathable, sufficiently light, sufficiently flexible, sufficiently resistant to high and low temperatures, and sufficiently comfortable.
    [0006] It was only after long mistakes and unsuccessful explorations that the present authors succeeded in obtaining a satisfactory element of protection. Thus, the present invention relates to a protective element in the form of a structure for absorbing and / or dissipating mechanical shocks comprising: connectors forming an aerated base having a base surface; and protuberances, each of the protuberances comprising a central axis along which it extends from the aerated base, the central axis being normal to the base surface, two neighboring protuberances being connected to each other by a connector. This structure is sufficiently ventilated while imparting mechanical properties of satisfactory impact resistance.
    [0007] By the term "aerated base" is meant here a base having orifices other than in front of the possible orifices of the protuberances. Thus, the base of the structure of the protective element of EP 2399470 is not aerated within the meaning of the present invention while that visible in Figures 1 to 4 attached is ventilated. In the examples illustrated in these figures, the airy character of the base is conferred in particular by the spaces between the connectors. By the term "base surface" it is always understood the surface of the aerated base from which extend the protuberances.
    [0008] 3035300 3 The term "normal" and its derivatives take their geometric meaning here. Thus, throughout the present discussion, when a relation of normality is mentioned with respect to the base surface, it should be understood that this relation is contemplated at the place considered and that the term "normal" means "perpendicular" at the tangent plane of the base surface at the considered location. For example, the central axis of a protuberance is said to be normal to the base surface when, at the point where the central axis of the protuberance is located, it is perpendicular to the tangent of the base surface to this place. The base surface may be planar, in which case the notions of normality and perpendicularity merge. The base surface may be curved to conform to the contours of the body portion of the wearer against which the structure is applied to protect that body part. Preferably, the structure has a breathability of 10 to 70%, preferably 18.5 to 58.5%, preferably 26.5 to 46.5%, preferably about 35%. This makes it possible to ensure adequate ventilation of the structure, making the wearing of the body protector more pleasant, as well as the wearing of the protective clothing in which the protector is provided, even during intense physical activity. Breathability is defined at the base area and corresponds to the percentage of the area of the base area corresponding to a vacuum relative to the total area of the base area. In addition or alternatively, the structure has a Shore A hardness of 5 to 90, preferably 11.5 to 68.5, preferably 18.5 to 46.5, preferably about 25. conditions to meet performance level 2 of EN1621-1: 2013 and / or performance level 1 of EN1621-2: 2014. The Shore A hardness is measured with a durometer according to DIN 53505: In addition or alternatively, the ratio between the height of the protuberances and the thickness of the aerated base is from 6 to 9, preferably from 6.5 to 8.5, preferably from 6 to 8, preferably about 7.5. . This ratio guarantees both the lightness, the breathability and the mechanical strength properties of the structure.
    [0009] The height of the protuberances corresponds to the height taken from the base surface of the ventilated base from which the protuberances extend to the free ends of the protuberances and parallel to the central axis of the protuberances. If the free end of the protuberances is not parallel to the base surface, the farthest level will be considered. The thickness of the aerated base is the thickness of the connectors (see below). The connectors preferably have a cylindrical shape, the director of the cylinder being collinear with the base surface. Thus, they may have a band shape whose surfaces are flat (cylindrical rectangular base). Alternatively, the connectors have a non-cylindrical shape, such as a curved or hollowed-out band shape. Preferably, the surface of the strips has a flat central part and two external parts inclined with respect to the central part so that the section of the collinear connector to the directrix and perpendicular to the base surface decreases as one moves away from the central part. The cylinder can also be circular, or polygonal (preferably regularly polygonal as square or hexagonal). In addition or alternatively, the connectors have a length of 0.01 to 25 mm, preferably 0.50 to 17.5 mm, preferably 1.0 mm to 9.5 mm, preferably 1.7 mm. The length of a connector is measured parallel to the base surface and between the outer walls of the protuberances that the connector connects directly and physically. The outer wall of the protuberances can be curved, so we will take the shortest length. In addition or alternatively, the connectors have a thickness of 0.1 to 1.4 mm, preferably 0.35 to 1.2 mm, preferably 0.55 to 1.0 mm, preferably about 0.80. mm. The thickness of the connectors, which is also the thickness of the aerated base, is normally measured at the base surface. The thickness of the connectors is not necessarily constant over the entire surface of the connectors, in such a case, it will be understood by "thickness" the maximum thickness. Thus, if each of the connectors is a curved strip at its center, the thickness is taken at the center; on the contrary, if each of the connectors is a hollow strip, the thickness is taken at its lateral edges.
    [0010] In addition or alternatively, the connectors have a width of 0.3 to 25 mm, preferably 1.2 to 17.5 mm, preferably 2.0 to 10.5 mm, preferably about 3.0 mm. . In addition or alternatively, the ratio between the equivalent outside diameter of the protuberances taken at the base surface and the distance between the central axes of two adjacent protuberances is 0.65 to 1.5, preferably 0.76 to 0.93, preferably 0.8 to 0.89, preferably about 0.85. Such a ratio ensures optimal flexibility of the structure without loss of mechanical properties conferring protection.
    [0011] The equivalent outer diameter corresponds to the diameter of a circle in which the outer wall of the protrusion, taken perpendicular to the central axis, is inscribed with a maximum of common points between the circle and the outer wall of the protuberance. In addition or alternatively, the distance between two adjacent protuberances is 6 to 60 mm, preferably 7.5 to 43.5 mm, preferably 9.5 to 27.5 mm, preferably about 11 mm. The distance between two adjacent protuberances is taken between the central axes of these protuberances and parallel to the base surface. In a particular embodiment, the protuberances are all present on the same side of the ventilated base. Alternatively, the protuberances are present on either side of the ventilated base, preferably the central axes of the protuberances on one side of the ventilated base are aligned with those of the protuberances on the other side of the ventilated base. Alternatively, the central axes of the protuberances on one side of the ventilated base are staggered relative to those of the protuberances on the other side of the ventilated base. In cases where the protuberances are present on both sides of the aerated base, the latter then has two base surfaces. In the case where the characteristics depend on a base surface, the base surface to contemplate is that from which the protrusion considered extends. In one embodiment, each protuberance having an outer wall, the outer wall has a symmetry of revolution about the central axis. In a variant, each protuberance having an outer wall, the outer wall is superposable on its image by rotation about the central axis of 360 ° / n angle where n is an integer strictly greater than 1, preferably strictly greater than 2; preferably 2 to 10, preferably 3 to 10, preferably 4 to 8, preferably 5 to 7, preferably 6. For example, the cross section of the outer wall is a regular polygon of 3 to 10 vertices, preferably 4 to 8, preferably 5 to 7, preferably 6. In one embodiment, the equivalent outer diameter of the protuberances is constant from the ventilated base. This means that the protuberances are straight cylinders (mathematical sense). Alternatively, the equivalent outer diameter of the protuberances decreases linearly from the aerated base with an angle greater than 00 and less than or equal to 30 °, preferably greater than 2 ° and less than or equal to 15 °, preferably greater than 4 ° and less than or equal to 8 °, preferably about 6 °. The angle of 6 ° is particularly designed to allow easy demolding of the structure of its mold. In addition, or alternatively, the equivalent outer diameter at the base surface is 3 to 25 mm, preferably 5 to 20 mm, preferably 7 to 14 mm, preferably about 9.5 mm. In addition, or alternatively, each of the protuberances is traversed by a through hole 15 extending along the central axis and defining an inner wall of the protuberance. This allows both to increase the breathability of the structure and to improve the lightness. Alternatively, the orifice is not through but blind on the side of the ventilated base which improves the lightness of the structure without changing its breathability.
    [0012] In one embodiment, the inner wall has symmetry of revolution about the central axis. In a variant, the inner wall is superposable on its image by rotation about the central axis of 360 ° / n angle where n is an integer strictly greater than 1, preferably strictly greater than 2; preferably from 2 to 10, preferably from 3 to 10, preferably from 4 to 8, preferably from 5 to 7, preferably 6. For example, the cross section of the inner wall is a regular polygon comprising 3 to 10 vertices, preferably 4 to 8, preferably 5 to 7, preferably 6. In the latter case, if the cross section of the outer wall is also a regular polygon, it preferably has the same shape as the cross section of the inner wall and the vertices these polygons are angularly aligned.
    [0013] In one embodiment, the equivalent inner diameter of the protuberances is constant from the ventilated base. The equivalent inner diameter corresponds to the diameter of a circle in which the inner wall of the protrusion, taken perpendicularly to the central axis, is inscribed with a maximum of common points between the circle and the inner wall of the protuberance. Alternatively, the equivalent inner diameter of the protuberances decreases linearly from the base surface with an angle greater than 00 and less than or equal to 30 °, preferably greater than 5 ° and less than or equal to 15 °, preferably greater than 4 ° and less than or equal to 8 °, preferably about 6 °. Alternatively again, the equivalent inner diameter of the protuberances increases linearly from the base surface with an angle greater than 0 ° and less than or equal to 30 °, preferably greater than 2 ° and less than or equal to 15 °, preferably greater than 4 ° and less than or equal to 8 °, preferably about 6 °. An angle of 6 ° is particularly studied to allow easy demolding of the structure of its mold. In addition or alternatively, the thickness of the protuberance is defined by the difference between the equivalent inner diameter and the equivalent outer diameter of the protuberance at the base surface. The thickness of the protrusion is 0.5 to 10 mm, preferably 0.65 to 7 mm, preferably 0.85 to 4 mm, preferably about 1 mm. In addition or alternatively, the height of the protuberances is 2 to 8.5 mm, preferably 3.5 to 7.5 mm, preferably 4.5 to 6.5 mm, preferably about 6 mm.
    [0014] The protuberances are preferably distributed in a regular mesh, for example in a square mesh (each of the protuberances having four neighbors) or regular triangular (each of the protuberances having six neighbors). Therefore, the connectors are the same length. The structure is preferably a flexible material. Hose means a material whose overall shape may be modified to conform more closely to the shape of the part of the body to which it is disposed. The flexible material is preferably a viscoelastic material, preferably with a glass transition temperature Tg of -20 to 50 ° C, preferably 0 to 40 ° C, preferably 15 to 25 ° C. The glass transition temperature Tg can be obtained by dynamic mechanical analysis using the METRAVIB instrument, type DMA + 450 from ACOEM. Although it is easier for manufacturing reasons to provide the ventilated base and the protuberances in the same viscoelastic material, it is also possible to provide that the ventilated base and the protuberances are made of different viscoelastic materials. It is even possible in these two cases to provide two or more populations of different protuberances, each being in a viscoelastic material different from the other 5. In the following description, the amounts of the compounds used in the composition of the viscoelastic material are expressed by weight relative to the total weight of the viscoelastic material. The major constituent of the viscoelastic material is a polymer such as polynorbornene, polyacrylonitrile, polyvinyl chloride (PVC), ethylene-vinyl acetate copolymer (EVA), chlorobutyl rubber (in English chlorobutyl rubber) and mixtures thereof. preferably polynorbornene alone or a mixture of polynorbornene with at least one of the other polymers mentioned above. By major constituent is meant the constituent present in greater quantity in the viscoelastic material. The viscoelastic material may advantageously comprise from 27 to 55% of polynorbornene, preferably from 40 to 50%, preferably from 42 to 48%, preferably about 45%. The viscoelastic material may also include a plasticizer such as an oil. Aromatic oils are preferred but it is also possible to use a paraffinic oil (PA), a naphthenic oil (HNA), a silicone oil or C9 resins (especially those supplied by Konimpex under the name "Hydrocarbon C9"). The viscoelastic material preferably comprises from 33 to 50% plasticizer, preferably from 37 to 45%, preferably from 39 to 43% by weight, preferably about 40%. The viscoelastic material may also include a filler such as silica, kaolin, aluminum oxide (Al (OH) 3), stearic acid powder or a mixture thereof. The viscoelastic material preferably comprises from 4 to 8% filler, preferably from 5 to 7%, preferably from 5.5 to 6.5%, preferably about 6%.
    [0015] The viscoelastic material may also include other compounds such as a preservative, an antioxidant, an anti-UV agent, an anti-scratch agent, a vulcanizing agent, a vulcanization accelerator and a coloring agent. Examples of preservatives are aluminum hydroxide (Al (OH) 3), metal oxides such as zinc oxide (ZnO) or titanium dioxide (TiO 2), ethylene vinyl acetate ( EVA), and an ethylene propylene-diene monomer (EPDM). The viscoelastic material may also be preservative free. Examples of antioxidants are phenolic antioxidants (for example 2,6-di-tert-butyl-4-methylphenol), phenyl-p-phenylene diamine and its derivatives such as N- (1-diamine, 3-dimethylbutyl) -N'-phenyl-p-phenylene (6PPD); the preferred antioxidants being phenyl-p-phenylene diamine and 6PPD. Examples of anti-UV agents are paraffin waxes and metal oxides such as zinc oxide (ZnO) or titanium dioxide (TiO 2). An example of an anti-scratch agent is N- (cyclohexylthio) phthalmide.
    [0016] Examples of vulcanizing agents are sulfur and di (benzothiazol-2-yl) disulfide (MBTS). Examples of vulcanization accelerators are titanium dioxide (TiO 2), N-cyclohexyl-2-benzothiazole sulphenamide (CBS), bis (N, N-dimethylthiocarbamyl) sulfide, stearic acid, blends of accelerators such as Deovulc EG 3 which is a synergistic combination of highly active accelerators containing ethylenethiourea, available from DOG Deutsche Oelfabrik and King Industries, Inc., and metal oxides such as zinc oxide (ZnO) or titanium dioxide (TiO 2), preferably stearic acid or mixtures of accelerators such as Deovulc EG 3.
    [0017] Examples of coloring agents are preferably organic and inorganic pigments such as iron oxides (such as yellow or red oxides), titanium dioxide (TiO 2), zinc oxide (ZnO) or carbon black . The structure of absorption and / or dissipation of mechanical shocks may be entirely homogeneous, that is to say that these connectors and protuberances are regularly arranged over the entire structure forming a single pattern and that the structure of absorption and / or dissipation of mechanical shocks is made in a single material. Alternatively, the absorption and / or dissipation structure 3035300 10 comprises several different zones. These zones may differ from each other either by at least one dimension of one of its elements (connectors, protuberances), or by the material used for the shaping of the zones, or by at least one dimension of one of its elements and by the material used for the shaping of the 5 zones. The invention also relates to a body protector at least partially made using the structure of absorption and / or mechanical shock dissipation described above. The term "body protector" herein refers to a suitably dimensioned mechanical absorption and / or shock dissipation structure or arrangement of such adequately sized structures to provide some protection to the part of the body facing the body. protection under normal conditions of use. In its simplest embodiment, the body protector is made entirely by means of the absorption and / or mechanical shock dissipation structure as described above. Examples of embodiment of body protector as to their shape are those presented in the standards EN1621-1: 2013 and EN1621-2: 2014 relating to protective clothing against mechanical shocks for motorcyclists.
    [0018] The body protector may be generally planar, that is, the aerated base of the thermal shock absorbing and / or dissipating structure of the component itself is planar. Thus, when it is integrated in a protective clothing, the body protector is folded, the free ends of the protuberances approaching or moving away from each other. In order to increase the flexibility of the body protector, it may have generally V-shaped cutouts, the tip being directed inwardly of the protector and the diagonals extending to the edge of the protector. The diagonals of the V can be straight or curved. In the case where the diagonals of the V are curved, they are curved on the same side. When folding, the diagonals of the V are brought together and then generally sealed to each other for example by gluing or welding, the protector then forming a dome to generally house the head or a joint such as the shoulder, the elbow or the knee. At the tip of the V a small circular cutout may be provided to facilitate the bending of the body protector at this location. By small size, it is here included a circular cutout of diameter less than 5 mm. The body protector may also be curved, that is to say that prior to its incorporation into a protective garment, it does not need to be folded: it already has the right curvatures adapted to the part of the body to protect. Thus, the structure of absorption and / or dissipation of mechanical shocks is shaped directly into the final form of use of the body protector. The body protector notably satisfies at least the performance level 1 of the EN1621-1: 2013 standard or the EN1621-2: 2014 standard, preferably the performance level 2. In particular, the body protector satisfies the level of performance 2 of EN1621-1: 2013 and performance level 1 of EN1621-2: 2014. The invention also relates to a protective clothing comprising a body protector as described above.

    [0021] The structure 1 for absorbing and / or dissipating mechanical shocks also comprises protuberances 3, each of the protuberances comprising a central axis AA along which it extends from the aerated base B, the central axis AA being normal to the base area. The protuberances 3 are present on one side of the aerated base B. Each protrusion 3 has an outer wall 31, the outer wall 31 having a symmetry of revolution about the central axis.

The inner wall 33 has a symmetry of revolution about the central axis AA. The protuberances 3 are distributed in a regular triangular mesh, that is to say that each of the protuberances has six neighbors and the central axes of the neighbors draw a regular hexagon. Another particular example of an absorption and / or dissipation structure according to the invention is described below with reference to FIG. 2. The structure 1 is homogeneous.

FIG. 3 shows an example of a section perpendicular to the aerated base for the examples of absorption and / or mechanical shock dissipation structures of FIGS. 1 and 2. In FIG. 3, the equivalent external diameter of protrusions 3 decreases 10 linearly from the aerated base B at an angle of 6 ° while the equivalent inner diameter Di of the protuberances 3 increases linearly from the aerated base B with an angle of 6 °.

This structure achieves performance level 2 for EN1621-1 and level 1 for EN1621-2.
    [0025] Referring to Figure 4, an example of body protector is described below. This example of body protector corresponds to the examples contained in the standard EN1621-1: 2013 (see Figure 1 and Table 1 of this standard). The body protector 10 can be defined simply using three parameters: two rays r1, r2 and a length /. It comprises three parts centered on a longitudinal axis BB which is also an axis of symmetry of the body protector 10. A first end portion 11 has the shape of a semicircle of radius r1 and a second end portion 12 has the form of a 'a semicircle of radius r2. The two end portions 11, 12 are connected to each other by a central portion 13 of trapezoidal shape and having as an axis of symmetry the longitudinal axis BB and a height /.
    [0026] Such a shape can be used to protect the following body parts: shoulder (S); elbow and forearm (E); hip (H); knee and upper shin (K); knee, upper and middle tibia (K + L); lower shin (L).
