Description

Title of the invention: Three-dimensional fabric made by knitting, garment made from such a fabric, equipment comprising such a garment and method of knitting such a fabric FIELD OF THE INVENTION

[0001] The present invention relates to the field of physical protection equipment such as that which may be worn by users exposed to bodily attacks.

[0002] More specifically, the invention relates to a fabric for manufacturing a garment with a protective function against physical attacks, in particular attacks using a sharp weapon. TECHNOLOGICAL BACKGROUND

[0003] In order to ensure optimal protection, protective clothing should preferably be easy to wear, i.e. easy to put on and take off, and also light, i.e. it limits little, if at all, the movements of the person wearing it.

[0004] The fabric from which the garment is made can be: • A fabric: that is to say a mesh formed by one or more weft threads which interweave one or more warp threads; • A knit: that is to say a set of loops made in one or more threads which are passed through each other.

[0005] It is therefore known to manufacture protective clothing that resembles classic, everyday clothing: a T-shirt, a jacket, trousers, etc. Such protective clothing is made from a fabric providing a protective function. The function is chosen according to the type of protection to be provided.

[0006] In order to provide the protective function, the fabric is made from one or more so-called technical yarns, i.e. yarns which have particular properties. In general, such a fabric provides limited comfort: it is rougher, more rigid, so that direct contact with the skin of a user is prohibited because irritations could occur. Thus, it is known to form with this fabric a protective garment that is worn over more conventional, more comfortable clothing, and to avoid any direct contact with the skin.

[0007] Such a fabric has several disadvantages. For example, it requires that the protective clothing be worn over conventional clothing: the user must therefore remember to put on the protective clothing when the situation requires it. In addition, the protective clothing must be correctly worn over the conventional clothing to cover the body optimally: a slip between the two clothing may cause a defect in protection.

[0008] It is then known to produce fabrics as a superposition of two layers: a technical layer made of technical yarn, and a comfort layer, made of yarn that is more pleasant for contact with the skin, for example yarn comprising wool or cotton. The two layers of the fabric are connected together by a so-called binding yarn, so as to keep them fixed relative to each other. The comfort layer is oriented towards the reverse of the garment, so as to provide comfortable contact with the user's skin.

[0009] For example, document EP3237659 describes a fire and heat resistant textile, intended in particular for firefighters. According to one example, the first layer is made in weft and warp by a modacrylic (60%) and cotton (40%) yarn, and the second layer is made in warp by a para-aramid yarn, or a mixture of modacrylic (60%) and cotton (40%), and in warp by a para-aramid yarn.

[0010] Document US2879654 proposes an undergarment offering protection against firearm bullets. The thread of the outer layer is a very high strength thread, for example nylon, and the inner layer, intended to be in contact with the skin, is made of a cotton / wool blend.

[0011] Document EP3545124 describes a fabric for clothing resistant to abrasion, and / or tearing and / or laceration and / or tearing and / or perforations. It comprises an upper layer, a lower layer and an intermediate layer. A thread connects the upper layer with the lower layer, and constitutes the intermediate layer. The upper layer is oriented outwards to protect against cuts and the lower layer is turned inwards in contact with the skin.

[0012] Such protective clothing therefore presents the technical yarn layer on the outside, that is to say that the technical layer will give the garment an aesthetic appearance, which will necessarily be limited. Indeed, the coloring of technical yarns is not always feasible depending on the nature of the yarn, and in all cases it involves an additional cost. In addition, the arrangement of the yarns of the technical layer must primarily meet the protective function, so that the mesh styles for forming the technical yarn layer are limited.

[0013] Therefore, a garment with a protective layer is easily distinguished to the naked eye from conventional yarn garments, particularly due to its limited aesthetic aspect. A user wearing such a garment is then more easily spotted, which can cause problems when discretion is required.

[0014] The invention thus aims to provide a solution in particular to the aforementioned drawbacks.

[0015] A first aspect of the invention is to propose a new fabric for producing a clothing that provides effective protection against attacks.

[0016] A second aspect of the invention is to propose a new fabric for producing a garment that increases discretion.

[0017] A third aspect of the invention is to propose a new fabric for producing a garment that is pleasant for the user to wear.

[0018] A fourth aspect of the invention is to propose a new fabric for producing a garment with enhanced aesthetics.

[0019] A fifth aspect of the invention is to provide a new fabric for making a wide range of clothing. Summary of the invention

[0020] Thus, the invention relates to a three-dimensional fabric made by knitting for the production of a so-called anti-laceration garment. By anti-laceration, we mean here a garment corresponding to at least the lowest level of the classification in accordance with the ISO13997 standard, and preferably corresponding to the highest level F of the ISO 13997 standard. The fabric comprises at least: • a first outer layer called the upper layer knitted from a first yarn, • a second outer layer called the lower layer knitted from a second yarn of a different nature from the first yarn, said second yarn giving the lower layer laceration resistance properties which are greater than those of the upper layer, • a third wire connecting the upper layer and the lower layer.

[0021] More particularly, the second yarn may be formed by assembling at least two other yarns and be knitted in single jersey to form the lower layer. Said lower layer is then intended to form an inner side of said anti-aggression garment, that is to say that it is oriented towards the skin side of a person wearing said garment.

[0022] The fabric thus formed has laceration resistance properties allowing it to be classified according to the ISO 13997 standard, and to form part of a complete anti-aggression assembly. The lower layer of the fabric is also particularly soft, allowing it to be in contact with the skin, so that the upper layer, with the first thread, can be produced in a conventional manner, with selected patterns and colors, in order to produce a discreet anti-laceration garment, having the appearance of a conventional garment.

[0023] According to different aspects, it is possible to provide one and / or the other of the characteristics below taken alone or in combination.

[0024] According to one embodiment, the second yarn may comprise a determined maximum count corresponding to the sum of the counts of the at least two yarns assembled to form it, said maximum count being between 350 and 650 Dtex. For example, said maximum titration is between 400 and 600 Dtex, and for example again, said maximum titration is equal to 440 Dtex.

[0025] Such titrations make it possible to obtain a good compromise between resistance to laceration and softness of the lower layer of the fabric.

[0026] According to one embodiment, the second wire can be produced by assembling at least identical wires, which makes it possible to limit storage and inventory problems.

[0027] According to one embodiment, the second thread can be made of polyethylene optimized to resist laceration. This is for example UHMW polyethylene, which makes it possible to achieve high performance in terms of laceration resistance.

[0028] According to one embodiment, the first thread can be made from natural fibers, in particular cotton and / or wool, in particular for the discretion of the garment made from the fabric, for the ease of handling these fibers, and their availability on the market.

[0029] According to one embodiment, the connecting thread may be of the same nature as the second thread, so as to maintain homogeneity in the nature of the threads on the lower layer, and to maintain the anti-laceration properties of the lower layer.

[0030] According to a second aspect, the invention relates to a garment made from the fabric as presented above, in which the second layer constitutes the reverse side of said garment, intended to be turned towards the skin of a person wearing said garment.

[0031] Indeed, the lower layer is soft enough to be in contact with the skin, so that the upper layer can be turned outwards, giving the appearance of a classic garment, thus offering increased discretion to the wearer of the garment.

[0032] According to a third aspect, the invention relates to anti-aggression equipment comprising a garment as presented above and an anti-ballistic device called a pack. The equipment further comprises a removable attachment system between the garment and the pack.

[0033] According to a fourth aspect, the invention relates to a method of knitting a fabric as presented above, comprising: • A step of simultaneous knitting of the upper layer and the lower layer connected by the third thread, in which the first thread is passed over a front bed, the second thread is passed over a back bed, and the third thread passes successively from the front bed to the back bed, and in which a bridge between the front bed and the back bed is made between each stitch; • A washing step in a bath.

[0052] The invention relates to a three-dimensional fabric 1 made by knitting for the production of a so-called anti-laceration garment. The garment is intended to be worn in contact with the skin of a user, without prohibiting the use of an undergarment in another fabric.

[0053] Knitting here means the production of a knit, that is to say a set of loops which are passed through each other and locked, so as to form a coherent stitch, in particular using needles.

[0054] By anti-laceration, we mean the property of the fabric to resist stresses during of an attack, in particular using a blade, in accordance with ISO 13997. More precisely, what is meant here is that fabric 1 corresponds to at least level A, i.e. the lowest level, of the classification in accordance with standard ISO13997, and preferably corresponding to level F, the highest, of standard ISO 13997.

[0055] The fabric 1 is said to be three-dimensional because it extends in three directions by the superposition of at least two layers linked together. More precisely, the fabric 1 comprises: • a first outer layer 2 called upper knitted from a first thread 3, • a second outer layer 4 called lower knitted from a second yarn 5 of a different nature from the first yarn 3, said second yarn 5 conferring laceration resistance properties to the lower layer 4 which are greater than those of the upper layer 2, • a third 6 wire called a connecting wire connecting the upper layer 2 and the lower layer 4.

[0056] In the following, the second yarn 5 will be described as a technical yarn, that is to say a yarn having particularly sought-after technical properties with regard to laceration, unlike the first yarn 3 which is described in the following as conventional, that is to say without any attempt to confer on it particular technical properties, other than conventional properties for making a garment, linked for example to aesthetics, warmth and / or softness.

[0057] The upper layer 2 and the lower layer 4 are said to be external because they are both intended to have one face facing the outside of the fabric 1, the other face of each layer 2, 4 being facing the inside of the fabric.

[0058] The upper layer 2 and the lower layer 4 thus extend one above the other, the connecting thread 6 passing successively through the loops of the upper layer 2 and the lower layer 4, so as to secure the two layers and ensure coherence for the fabric 1. Preferably, the connecting thread 6 tightens the layers 2, 4 so as to prevent one from slipping relative to the other. More precisely, the two layers 2, 4 are handled and felt by the user of the garment made from the fabric 1 as a single layer.

[0059] The lower layer 4 is intended to form an inner side of the anti-laceration garment, that is to say it is intended to be oriented towards the skin of a person wearing said garment. Thus, the softness to the touch of the lower layer 4 must be sufficient to provide the comfort necessary for contact with the skin. Softness, although being a subjective criterion, can be evaluated by a panel of users expressing their feelings when wearing the anti-laceration garment, the feeling when touching it in comparison with a fabric made of natural materials such as cotton or wool, and the absence of skin irritation when wearing the garment made from this fabric 1. The combination of the softness of the lower layer 4 and the anti-laceration properties is obtained in particular thanks to the following characteristics of the technical yarn 5.

[0060] The second yarn 5 is formed by assembling at least two yarns 7, 8, that is to say that the technical yarn 5 is obtained by taking at least two separate yarns 7, 8, themselves technical, and assembling them for knitting. According to one embodiment, which is that of the figures, the second yarn is formed by assembling two yarns 7, 8. More precisely, the two yarns 7, 8 forming the second yarn 5 are used as forming a single yarn. Even more precisely, the two assembled yarns 7, 8 are passed through the same knitting needle head A as a single yarn to form the lower layer 4. For example, the two yarns 7, 8 can be twisted to form the second yarn 5.

[0061] The second yarn 5 is knitted in single jersey to form the lower layer 4. In fact, the single jersey stitch ensures the density and homogeneity of the lower layer 4 in order to obtain sufficient tightening of the loops of the knit, and to confer the desired anti-laceration properties, while being suitable for forming the three-dimensional fabric 1 by the connection with the third yarn 6.

[0062] The two threads 7, 8 assembled to form the second thread 5 are made of so-called technical material, conferring the properties of resistance to laceration. According to one embodiment, the two threads 7, 8 assembled to form the second thread 5 are in the same material. Each thread 7, 8 is for example formed of braided or twisted fibers. Alternatively, each thread 7, 8 comprises a fiber core and a coating forming an envelope around the fibers. According to one embodiment, the second thread 5 is made of polyethylene optimized to resist lacerations. For example, the second thread 5 is made of so-called ultra-high molecular weight polyethylene (PE-UHMW). An additional treatment can be carried out in order to reinforce the threads 7, 8 assembled to form the second thread 5 and confer the desired anti-laceration properties. For example, the wires 7, 8, before or after assembly to form the second wire 5, can be immersed in one or more baths of determined additives.

[0063] The second 5 has a determined maximum count which is between 350 and 650 Dtex (decitex), and which corresponds to the sum of the counts of two yarns 7, 8 assembled to form the second yarn 5. Indeed, it has been determined that below 350 Dtex, the anti-laceration properties are not adequate, and above 650 Dtex, the softness of the lower layer 4 is not satisfactory for forming the inner side of the anti-laceration garment. According to one embodiment, the count of the second yarn 5 is between 400 and 600 Dtex and is for example equal to 440 Dtex.

[0064] According to one embodiment, the two wires 7, 8 assembled to form the second wire 5 are identical, that is to say they have the same count and are made of the same material. For example, the count of each of the threads 7, 8 is equal to 220 Dtex, and they are both made of PE-UHMW, possibly treated.

[0065] According to one embodiment, the first yarn 3 is made of natural fibers such as cotton, pima cotton or wool, or any other fiber conventionally used to make everyday clothing without particular technical properties. The mesh of the upper layer 2 is for example of the single jersey type, but may be other. The choice of the mesh of the upper layer 2 may respond to aesthetic choices. For example, the mesh is chosen to make patterns on the outer layer 4. The first yarn 3 may also have different colors on different places of the upper layer 2, again for example to form patterns for aesthetic purposes. Since the upper layer 2 does not require particular anti-laceration characteristics, the choice of the first yarn 3, the mesh and the colors may be guided solely by aesthetics, and the usual considerations with this type of yarn.In addition, the association of the upper layer 2 with the lower layer 4 resistant to lacerations limits the risks of deformation of the upper layer 2. The first thread 3 can be a single thread, that is to say formed from a single thread, or be formed by the assembly of at least two threads assembled and passed through the same needle head. The count of the first thread 3 is then for example Nm (metric number) 2 / 34.

[0066] The connecting thread 6 interweaves the loops of the upper layer 2 and the lower layer 4, so as to locally form part of the upper layer 2 and the lower layer 3. In order not to degrade the anti-laceration properties of the lower layer 4, the connecting thread 3 is preferably a technical thread with anti-laceration properties, for example in the same material as the second thread 5. It is preferably a single thread, that is to say a single thread passed through the head of a needle. Its count is for example 220 Dtex.

[0067] Surprisingly, the lower layer 4 thus obtained has sufficient softness to be in contact with the skin, offering comfort similar to that of a 100% natural fiber fabric. Without linking this result to a particular theory, it has been noted that the use of at least two yarns 7,8 assembled to form the second yarn 5 knitted to form the lower layer 4 makes it possible to obtain improved softness compared to the formation of a layer of technical yarn with a single single yarn. Indeed, the use of at least two yarns 7,8 to obtain a determined count for the second yarn 5 reduces the rigidity of the lower layer 4 compared to the use of a single yarn of the determined count. The single jersey stitch also contributes to providing the softness of the lower layer 4, while providing sufficient mesh density to confer the anti-laceration properties.The jersey mesh is also particularly suitable for the implementation of the connecting thread 3 between the upper layer 2 and . the lower layer 4.

[0068] An example of a manufacturing process by knitting the fabric 1 will now be described, illustrated in [Fig.6].

[0069] Fabric 1 is knitted for example on a flat knitting machine model Vesta VD from Steiger in gauge 10.

[0070] In order to form a first stitch, the first thread 3 is placed on the needles of a front needle bed of the machine, and the second thread 5 is placed on the needles of a rear needle bed of the machine. The third thread is passed successively between the needles of the front needle bed and the needles of the rear needle bed. A first stitch of the fabric 1 is thus formed.

[0071] To form a second stitch, the operations of placing the first thread 3, the second thread 5 and the third thread 6 on the needles are repeated, with a cross-stitch between the rear needle bed and the front needle bed relative to the formation of the first stitch. A second stitch of the fabric 1 is then formed.

[0072] The third stitch is formed in a similar manner to the first stitch, the fourth stitch is formed in a similar manner to the second stitch, and so on until all the stitches of the fabric 1 are formed. In other words, the stitches are formed successively with, between each stitch, a trestle between the front needle bed and the back needle bed.

[0073] Thus, the upper layer 2 and the lower layer 4 are knitted simultaneously. Once the knitting step has been carried out, the fabric 1 may undergo a washing treatment in a bath specially designed to adjust the tension in the stitches of the knit in order to ensure dimensional stability of the fabric 1 and of the garment made from said fabric 1, and / or to further soften the fabric 1 if necessary.

[0074] The fabric 1 thus produced can be used to manufacture all or part of an anti-laceration protective garment 10. The knit offers a visual rendering that is particularly suitable, but not limited, to upper body garments such as sweaters, vests and T-shirts.

[0075] According to one embodiment, the garment 10 made from the fabric 1 is a sweater. The fabric 1 can be used to make the entire sweater 10. However, the edges of the sweater such as the cuffs, the collar and / or the bottom of the sweater can be made from another fabric as will be explained later.

[0076] According to this embodiment, the sweater 10 can be knitted in the fabric 1 in several pieces. For example, the sweater 10 is made by knitting the fabric 1 separately to form a front bib 11, a back bib 12 and the sleeves 13. Then, the pieces are assembled to obtain the sweater. The bottom 14 of the front bib 11 and the bottom 15 of the bib 12, as well as the edges 16 of the arms, at the wrists, can be knitted in a stitch different from that of the fabric 1, in order for example to provide a finished appearance and / or provide elasticity. Elasticity can also be increased by adding a more elastic yarn to the knitting stitch of the edges 14, 15, 16 than the yarns 3, 5 and 6 of the fabric 1. The front plastron 11, the back plastron 12 and the sleeves are then assembled to form the garment 10.

[0077] The collar 17 of the sweater 10 can also be formed in a different mesh from that of the fabric 1.

[0078] The garment 10 may comprise a so-called high collar 17, that is to say it covers part of the neck of the user of the garment 10. In the case of a sweater, this is called a turtleneck or high collar. Since the neck is a particularly vulnerable area, the anti-laceration properties of the collar 17 of the garment can be reinforced. According to an exemplary embodiment, the high collar 17 is made by knitting a strip, a first half of which is knitted with a so-called technical yarn, and the second half is knitted with a yarn made of natural fibers such as cotton or any other natural fiber, preferably of the same nature as the natural fiber used for the upper layer 2 of the fabric 1 used for the garment 10. The technical yarn is for example of the same nature as the second yarn 5 of the fabric 1, that is to say polyethylene.The knit of the stand-up collar is for example a 1x1 rib with a gauge, the technical yarn being of the same nature as the yarn 5 of the lower layer 4 of the fabric 1 used for the garment 10. In order to reinforce the stand-up collar, the count of the technical yarn may be higher than the count of the second yarn 5 to make the fabric 1. For example, the count of the technical yarn for the collar is 660 Dtex, and is obtained by joining two or even three yarns. The strip thus knitted is folded back on itself, the first half in technical yarn being superimposed on the second half, to form the collar 17 comprising two superimposed layers, each layer corresponding to one half of the initially knitted strip. The collar is then joined to the rest of the garment, the layer corresponding to the first half in technical yarn being oriented towards the reverse, that is to say it is intended to be in contact with the user's skin.By using the 1x1 gauged mesh, the elasticity of the collar is increased compared to the rest of the garment, to facilitate the passage of the wearer's head while keeping the collar 17 in position to cover the neck and protect it. The high count of the technical yarn layer of the collar 17 increases the resistance to lacerations, providing optimal protection on the neck.

[0079] The fabric 1 makes it possible to form any type of garment, which can then be worn discreetly like an ordinary-looking garment, the layer 4 providing the anti-laceration properties not being visible when the garment is worn.

[0080] The garment 10 formed from the fabric 1 thus makes it possible to provide effective protection against lacerations, in accordance with the ISO 13997 standard, while remaining discreet. In particular, tests carried out in accordance with the ISO 13997 standard made it possible to classify the fabric 1 at level F, which is the highest level, i.e. as re resistant to an applied load greater than or equal to 30N (Newtons). More precisely, the test according to ISO 13997 consists of moving a blade over a determined distance on a sample of fabric 1, gradually loading the blade, and determining the load necessary to obtain the cut of fabric 1 when the blade is moved over 20 mm, using a computed tomography (CT) scanner. For example, in the case where fabric 1 is made using a first cotton yarn 3 with a count Nm 2 / 34 for the upper layer 2, a second yarn 5 comprising two yarns 7, 8, each with a count of 220 Dtex in polyethylene for the lower layer 4, with a double-sided jersey knitting, the load to achieve the cut of the fabric is greater than 30N, more precisely is greater than 35N, even more precisely is equal to 40N. More generally, garment 10 made from fabric 1 is classified as level F.Thus, in addition to fabric 1, in the case of collar 17 in 1x1 gauged mesh, the layer of technical yarn being made of three assembled yarns, in polyethylene with a count of 220 Dtex each and the other layer being made of cotton with a count Nm 2 / 34, the load to make the cut of collar 17 is greater than 30N, more precisely, greater than 40N, more precisely still greater than 50 N, and is for example equal to 56.3 N.

[0081] Furthermore, the garment 10 can be combined with an additional anti-ballistic device, to provide complete anti-aggression protection.

[0082] Thus, the invention proposes anti-aggression equipment 100 comprising the anti-laceration garment 10 for the upper body associated with an anti-ballistic device for the upper body, called pack 20, which is removably attached to the garment 10.

[0083] By antiballistic, we mean a product meeting the NU (National Institute of Justice) standard. In this case, the NU has defined several levels of protection depending on the maximum kinetic energy stopped by the antiballistic device. A performance level of the NU standard means that the antiballistic device meets the minimum performance requirements defined by the NU for this level. For example, the pack 20 used corresponds to the minimum at level IIA, or even III+ of the NU.

[0084] Although in the example below the anti-laceration garment 10 is made from the fabric 1 described above, a garment made from any other fabric with anti-laceration properties may also be suitable. However, the garment 10 made from the fabric 1 is particularly lightweight, making it particularly suitable for association with an anti-ballistic pack. Furthermore, the removable properties of the pack 20 can be advantageously combined with the discretion of the fabric 1: by removing the pack 20, the garment 10 can be worn as an ordinary-looking garment.

[0085] The garment 10 is an upper body garment, and in particular a sweater, a T-shirt, a shirt or a vest.

[0086] More specifically, for this purpose, the equipment 100 comprises a fixing system removable in two parts: a first part 101 fixed on the garment 10 and a second part 102 fixed on the pack 20. The two parts 101, 102 of the fastening system are complementary to each other to provide the removable fastening. By removable, we mean here the fact that the fastening can be removed and replaced manually and successively a plurality of times, without degrading the integrity of the garment 10 and / or the pack 20.

[0087] Preferably, the two parts 101, 102 are rigidly fixed respectively to the garment 10 and the pack 20, that is to say that each part 101, 102 is intended to remain permanently in place on the garment 10 and the pack 20 respectively.

[0088] Thus, the equipment 100 can take two positions: • An assembled position, in which the garment 10 and the pack 20 are fixed to each other, the first part 101 of the fixing system being locked onto the second fixing part 102, so as to form a protective assembly; • A separate position, in which the garment 10 and the pack 20 are separated from each other, so that they can be handled independently of each other.

[0089] In the assembled position, the equipment 100 forms the protective assembly which thus provides complete anti-aggression protection. In the separate position, the garment 10 can be worn alone in order to provide anti-laceration protection.

[0090] According to one embodiment, the fastening system 101, 102 is of the self-gripping type, and comprises a male part formed of hooks and a female part formed of loops cooperating with the hooks of the male part to provide adhesion between the two parts.

[0091] According to one embodiment, the female part of the self-gripping system corresponds to the part 101 fixed to the garment 10, and the male part corresponds to the part 102 fixed to the pack 20.

[0092] More precisely, the part 101 fixed to the garment 10 comprises two female strips 103 each fixed at the level of a shoulder of the garment, on the inside of the garment, that is to say on the side towards the skin of the user when the garment 10 is worn. The fixing of each female strip 103 is carried out for example astride the front plastron 11 and the rear plastron 12, by the middle of the strip corresponding to the junction between the front plastron 11 and the rear plastron 12. The fixing of the strip 103 is carried out by sewing and / or by gluing on the garment 10.

[0093] The pack 20 comprises a front panel 21, intended to cover in particular the torso of the user who wears it and a rear panel 22 intended to cover in particular the back of the user. Each panel 21, 22 is made for example by a plate of anti-ballistic material covered with a fabric, by a cloth or a knit, sufficiently soft to be in contact with the user's skin. The part 102 of the fastening system fixed to the pack 20 can then comprise four male strips 104, 105, namely two front male strips 104 on the front panel 21 and two rear male strips 105 on the rear panel 22. The pack 20 is then assembled to the garment 10 by placing each female strip 103 straddling a front male strip 104 and a rear female strip 105.

[0094] The two panels 21, 22 can be sewn together, or be presented separately from each other.

[0095] In order to tighten the panels 21, 22 around the upper body, the equipment 100 may further comprise a removable tightening system for the panels 21, 22. The tightening system for the panels 21, 22 of the pack 20 may also be of the self-gripping type. In this case, the tightening system may comprise two straps 106, two opposite end regions 107 of which are provided with a first part of a fastening system, for example the hooks forming the male part of a self-gripping system. In a complementary manner, the front panel 21 then comprises a tightening surface 108 provided with a second part of a fastening system, for example the loops of the female part of a self-gripping system, and the rear panel 22 comprises a tightening surface 109 also provided with loops.

[0096] According to one example, in order to form the anti-aggression equipment 100, the two panels 21, 22 of the pack 20 are connected to each other by means of the tightening system around the user's body. More precisely, each strap 106 is connected to a panel 21, 22: a first end region 107 of the strap is fixed on the tightening surface 108 of the front panel 21 and the second region 107 of the strap 106 is fixed on the tightening surface 109 of the rear panel 22. The adjustment on the user's body can be adjusted by positioning the end regions 107 of the straps 106 on the tightening surfaces 108, 109.

[0097] The user then puts on the garment 10, in this case the sweater, over the pack 20. Each female strip 103 of the garment 10 covers a front strip 104 and a rear male strip 105, so as to straddle the front panel 21 and the rear panel 22, ensuring the connection between the garment 10 and the pack 20. The position of the garment 10 is thus locked relative to the pack 20 at the user's shoulders.

[0098] To separate the garment 10 from the pack, the user removes the garment 10 like a conventional garment, exerting a greater tensile force at the bands 103, 104, 105 to break the connection and the locking.

[0099] Any other way of forming and removing the anti-aggression equipment 100 may also be suitable.
