Description

Title of the invention: RIDING HARNESS AND METHOD FOR MANUFACTURING SUCH A HARNESS Technical field

[0001] The invention relates to a roping harness and to a method of manufacturing a roping harness. Prior art

[0002] For activities at height, it is conventional to use a rope harness which has a belt and a pair of leg loops. The rope harness is equipped with an adjustment system which is configured to adjust the circumference of the belt.

[0003] Conventionally, in rope harnesses for climbing or mountaineering, the belt or leg loop is formed by one or more resistance straps which are attached to a support element which is a comfort foam, a woven material or a knitted material. The dimensions of the resistance threads and the resistance straps as well as their attachment positions are chosen to withstand the forces during a fall and to better distribute the forces against the user's body.

[0004] The support is functionalized in particular as equipment holders which are intended to support carabiners, shackles and other equipment of the climber or mountaineer. Since the support does not have significant mechanical strength, the equipment holders must be attached to the resistance wires and straps.

[0005] There are a few precautions to take when attaching the equipment holder in order to best distribute the stress on the resistance wires / straps and to ensure good longevity of the attachment seams.

[0006] A similar problem exists for all equipment that must be attached to the belt and / or thigh circumference, such as the straps of the belt / thigh circumference adjustment device.

[0007] A means is therefore sought to improve the attachment of equipment with the support intended to form the belt or the thigh strap.

[0008] It is also known from document US 2019 / 0308040 to form a roping harness by means of two woven layers which are formed independently of each other and which are superimposed and fixed in order to define a cavity. The cavity is intended to receive a comfort foam so as to change the comfort level of the roping harness and to change the compromise between weight and comfort. The two woven layers are connected by a sewn resistance strap to ensure mechanical support with the ventral suspension point. Subject of the invention

[0009] An object of the invention is to provide a harness which has better management of the functionalization of a belt or a leg loop and for example better installation of equipment such as a material holder or a strap of an adjustment device with a support intended to form the belt or the leg loop of the harness.

[0010] According to one aspect of the invention, the roping harness comprises a waist belt, a pair of leg loops, a woven layer shaped into a loop to form one of the waist belt and a leg loop and a closure secured at first and second ends of the woven layer opposite each other in a first direction.

[0011] The woven layer has first threads attached to the closure and extending continuously from the first end to the second end.

[0012] The woven layer comprises an outer sheet and an inner sheet which are superimposed and which are each woven.

[0013] The woven layer comprises outer longitudinal yarns and outer transverse yarns woven to form the outer web and inner longitudinal yarns and inner transverse yarns woven to form the inner web.

[0014] The inner ply and the outer ply are connected to each other by the interlacing of at least one connecting thread intertwining in the inner ply and in the outer ply so that the inner ply and the outer ply deform in the same way at least in the first direction, the at least one connecting thread being chosen from the inner longitudinal threads, the inner transverse threads, the outer longitudinal threads, the outer transverse threads and at least one binding thread, the at least one binding thread being woven with the inner ply and the outer ply.

[0015] The woven layer forms at least one cavity delimited on the one hand by a support and on the other hand by a cover fixed to each other by at least two anchors, each cavity being intended to receive an object between the cover and the support.

[0016] A portion of the internal sheet forms the support of the at least one cavity.

[0017] The cover of the at least one cavity comprises cover wires connecting the two anchors, the cover wires being chosen from internal longitudinal wires, internal transverse wires, external longitudinal wires, external transverse wires and the binding wire.

[0019] Advantageously, the cover wires bypass at least one of the wires of the internal sheet to fix the cover to the internal layer, said at least one of the wires of the internal sheet belonging to the first five wire bypasses made by the cover wire leaving the cover.

[0020] In a particular configuration, in the anchors, the cover wires pass through the outer ply and bypass at least one of the inner longitudinal wires or one of the inner transverse wires to directly fix the cover to the inner layer.

[0021] In an advantageous development, the hood is a woven hood formed by weaving the hood yarns with other yarns selected from the inner longitudinal yarns, the inner transverse yarns, the outer longitudinal yarns, the outer transverse yarns and the binding yarn.

[0022] Preferably, the external sheet forms the cover and the internal sheet forms the support.

[0024] In an advantageous development, the at least one tunnel comprises a tunnel which passes through in a second direction perpendicular to the first direction.

[0025] Preferably, the at least one tunnel extends continuously from a first edge to a second opposite edge of the woven layer in the second direction.

[0026] In another advantageous development, the at least one tunnel comprises a blind tunnel in a second direction perpendicular to the first direction.

[0027] Preferably, the cover is non-woven, the cover threads only comprise internal transverse threads and / or external transverse threads and / or binding threads extending in a second direction perpendicular to the first direction.

[0030] Preferably, the rope harness comprises at least two tunnels. The object is a wire element connecting the two tunnels, the wire element being fixed to at least one of the support or the cover of each tunnel.

[0031] In a particular configuration, a seam secures together the wire element, the cover and the support of each tunnel and secures the wire element to at least one of the first wires.

[0032] Advantageously, the rope harness comprises at least three tunnels offset in the first direction, at least one of the tunnels passing through in a second direction perpendicular to the first direction and forming a central tunnel arranged between the two other tunnels in the first direction, the wire element passing through the central cavity and extending to the two other tunnels by two separate strands.

[0033] Preferably, the at least one tunnel is a blind hole according to the first direction.

[0034] In another advantageous development, the hood is a woven hood formed by weaving the hood yarns with other yarns selected from the inner longitudinal yarns, the inner transverse yarns, the outer longitudinal yarns, the outer transverse yarns and the binding yarn.

[0035] In a particular configuration, the inner sheet forms the support and the outer sheet forms the cover.

[0054] Figures 1 to 12 illustrate different embodiments of a roping harness which comprises a belt 1 and a pair of leg loops 2. As illustrated in Figures 1 and 2, the harness also comprises a woven layer 3 arranged in the form of a ring and intended to form one of the belt 1 and a leg loop 2. The ring is closed by means of a closure 4. The closure 4 is fixedly arranged at a first end 3a and at a second end 3b of the ring. The first end 3a and the second end 3b are opposite in the direction XX.

[0055] Depending on the embodiments, the closure 4 is selected from an adjustment system 5 configured to adjust the circumference of the woven layer 3 shaped into a ring, an opening-closing system configured to open and close the ring, or a seam that securely holds the two ends of the ring in place. [Fig. 2] illustrates different adjustment systems 5 that are also systems opening-closing.

[0056] The adjustment system 5 preferably comprises a first element and a second element which cooperate with each other to adjust the circumference of the ring. Advantageously, the first element is a first strap element 5a and the second element is a second loop element 5b. The second loop element 5b has a loop which is crossed by a strap of the first strap element 5a to adjust the circumference. The first strap element 5a and the second loop element 5b are fixedly arranged at each of the ends of the woven layer 3 in the first direction XX. The strap of the first strap element 5a is wedged in the loop of the second loop element 5b to fix the circumference of the ring. The opening-closing system is associated with the woven layer 3 in the same way with a first element fixed to the first end 3a and a second element fixed to the second end 3b.

[0057] As illustrated in Figures 3, 4, 5, 6, 7 and 10, the woven layer 3 comprises longitudinal yarns 6 and transverse yarns 7 woven together to form a weave. The longitudinal yarns 6 extend in the first direction XX while the transverse yarns 7 extend in the second direction YY perpendicular to the first direction XX. The weave extends continuously from the first end 3a to the opposite second end 3b in the first direction XX. The weave extends continuously from the first edge 3c to the opposite second edge 3d in the second direction YY.

[0058] The longitudinal wires 6 comprise first wires 6a. Each first wire 6a extends continuously in the first longitudinal direction XX from the first end 3a to the opposite second end 3b to ensure the expected mechanical strength of the belt 1 or the thigh strap 2 during a fall. The first wires 6a are fixed to the closure 4 to ensure the mechanical integrity of the ring in the closed position in the event of a fall.

[0059] The transverse wires 7 comprise second wires 7a which extend in the second direction YY. The second wires 7a extend continuously from the first edge 3c to the opposite second edge 3d in the second direction YY and they connect the first wires 6a, preferably all the first wires 6a.

[0060] The woven layer 3 comprises first yarns 6a and second yarns 7a which are interlaced in order to provide the expected mechanical performance in the first direction XX and the second direction YY. Advantageously, the woven zone has a first zone whose woven longitudinal yarns are only first yarns 6. The first woven zone extends continuously in the second direction YY. Preferably, the first woven zone is unique, that is to say that all the first yarns 6a are included in the first zone. The first woven zone is formed only by the first threads 6a which ensures the mechanical resistance of the woven layer 3 in the direction XX in the event of a fall in order to ensure the integrity of the ring.

[0061] The first wires 6a may comprise only wires of identical or substantially identical resistance to ensure that a predefined mechanical resistance is obtained along the first direction XX. Alternatively, the first wires 6a may comprise wires having different mechanical resistances in order to have a better compromise between the mechanical resistance and the surface area occupied by the first wires 6a along the second direction YY. The nature of the first wires 6a as well as their sections are defined so as to obtain the desired mechanical performance along the first direction XX. Advantageously, all the first wires 6a are identical.

[0062] To improve comfort when the user is suspended in his harness, it is advantageous to have a mechanically active contact surface which is as large as possible in the second direction YY to stress a large number of first wires 6a. However, the width of the harness cannot be increased too much so as not to penalize its comfort outside of suspended situations, its weight and, where appropriate, its compressibility.

[0063] The woven layer 3 has a thickness which is defined by the diameters of the threads used and the weave(s) applied.

[0064] As illustrated in Figures 3, 4, 5 and 6, the woven layer 3 comprises at least a first ply and a second ply which are superimposed and bonded to each other to define at least an inner ply 10 and an outer ply 11 in the direction of the thickness. The outer ply 11 is the outermost ply of the stack, i.e. the last ply, the one which is not covered by another ply. The inner ply is the closest to the user of the two ply.

[0065] The at least two plies are woven plies. The outer ply 11 has outer yarns with outer longitudinal yarns and outer transverse yarns 7n that are woven together. The inner ply 10 has inner yarns with inner longitudinal yarns and inner transverse yarns 7i0 that are woven together. The inner longitudinal yarns and the outer longitudinal yarns are longitudinal yarns 6 that extend in the first direction XX at least one of the two plies and preferably both plies have first yarns 6ai0 and 6an. The inner transverse yarns 7i0 and the outer transverse yarns 7n are transverse yarns 7 that extend in the second direction YY. At least one of the two plies and preferably both plies have second yarns 7ai0 and 7an.

[0066] The inner sheet 10 and the outer sheet 11 are mechanically connected together so that the two sheets deform together in the first direction YY and preferably in the second direction YY. The mechanical connection between the two plies can be obtained by different means when weaving the plies. The plies are mechanically held together by at least one connecting thread 12 according to one or more weaving patterns that are known. The at least one connecting thread 12 entangles in the inner ply 10 and in the outer ply 11 in the direction of the transverse threads and / or in the direction of the longitudinal threads to bypass internal and external threads and ensure the mechanical connection between the plies. The entanglement pattern can be any.

[0067] The mechanical connection between the inner ply 10 and the outer ply 11 is obtained by an inversion of the outer longitudinal threads and the inner longitudinal threads and / or by an inversion of the outer transverse threads and the inner transverse threads which then form the binding threads. In other words, an outer thread replaces an inner thread to weave into the inner ply and an inner thread replaces an outer thread to weave into the outer ply. Then the thread returns to its original ply. Alternatively or in addition, the at least one binding thread is an additional thread to the inner and outer threads and called binding thread 12.

[0068] The longitudinal threads and / or the transverse threads can be bonded in the internal layer or in the external layer, by convention, the internal longitudinal threads and the internal transverse threads have a majority of entanglements with the threads present in the internal layer. For example, the internal longitudinal threads and the internal transverse threads are mainly entangled with each other. The external longitudinal threads and the external transverse threads have a majority of entanglements with the threads present in the external layer. For example, the external longitudinal threads and the external transverse threads are mainly entangled with each other.

[0069] The woven layer 3 defines at least one cavity 13 which will form a tunnel intended to receive an object, for example a wire element 14 or a connector. The cavity 13 is delimited on the one hand by a support 15 and on the other hand by a cover 16. The cover 16 is connected to the support 15 by two anchors 9 arranged opposite each other in the longitudinal direction XX or in the transverse direction YY. Between the two anchors 9, the cover 16 and the support 15 are not connected by the connecting thread(s). The distance between two anchors 9 is preferably at least equal to 5 threads, preferably at least equal to 10 threads. [Fig.7] illustrates different embodiments of cavities.

[0070] A portion of the internal sheet 10 forms the support 15 while the cover 16 is formed by cover threads which connect the two anchors 9 and which are among the internal longitudinal threads, the internal transverse threads, the external longitudinal threads, the external transverse threads and the binding thread.

[0071] Depending on the configurations, the cover 16 may be a woven or non-woven material. In a woven material, it is possible to identify a weaving pattern with transverse threads and longitudinal yarns. When the cover is non-woven, the cover has only longitudinally extending yarns or transversely extending yarns.

[0072] Preferably, the texture of the internal longitudinal threads and the external longitudinal threads is constant from the first end 3a to the second end 3b. It is also advantageous for the texture of the internal transverse threads and the external transverse threads to be constant from the first edge 3c to the second edge 3d. The same may be true for the binding thread if necessary. Consequently, for a given dimension in the transverse direction or in the longitudinal direction, the number of threads is constant. The assembly representing the cover 16 and the support 15 is formed by the same number of longitudinal threads as the threads used on one side or the other of the tunnel in the longitudinal direction XX. The assembly representing the cover 16 and the support 15 is formed by the same number of transverse threads as the threads used on one side or the other of the tunnel in the transverse direction XX.

[0073] For example, the internal sheet 10 only comprises the internal wires and forms the support 15 and the external sheet only comprises the external wires and forms the cover 16. One or more internal wires can be exchanged with the same number of external wires to modify the mechanical characteristics of the support 15 or the cover 16.

[0074] It is possible to have a cover 16 having more transverse wires or more longitudinal wires than the immediately adjacent external sheet 11 (for a given dimension) and the support has fewer transverse wires or more longitudinal wires to compensate. The reverse is also possible.

[0075] When the cover 16 is a non-woven material, it only comprises yarns oriented longitudinally or transversely. The cover yarns are chosen from the internal transverse yarns and the external transverse yarns or the cover yarns are chosen from the internal longitudinal yarns and the external longitudinal yarns. When the woven layer 3 has one or more binding yarns 12, the binding yarn 12 can also form one or more of the cover yarns depending on whether it extends in the transverse direction YY or the longitudinal direction XX and depending on the orientation of the cavity 13. The transverse and / or longitudinal yarns which are not used to form the cover are present in the support 15. The same can be true for the binding yarn 12 if necessary.

[0076] In one embodiment, the cavity 13 is a through cavity, i.e. it is possible to introduce a wire element or a connector through each of the two ends of the cavity 13. In one embodiment, the two ends are separated along the longitudinal direction XX and the two anchors 9 are opposite each other along the transverse direction YY. In another embodiment, the two ends are separated along the transverse direction YY and the two anchors 9 are opposite each other. along the longitudinal direction XX.

[0077] In an alternative embodiment, the cavity 13 is a blind hole. This embodiment is preferably intended for the fixing of a wire element 14.

[0078] In a particular embodiment, the wire element 14 is introduced into the cavity 13 between the inner ply 10 and the outer ply 11. The wire element 14 is fixed to first wires 6a, preferably by a seam 8. It is advantageous if the seam 8 is used to fix together the inner ply 10, the outer ply 11 and the wire element 14. The support 15 and / or the cover 16 have first wires 6a which belong to a wall of the cavity 13. The first wires 6a partly define the cavity 13 and they are fixed to the wire element 14. By means of the sewing fixing, the cover 16 is mechanically linked to the support 15.

[0079] The anchoring of the cover 16 with the support 15 is formed by the multiple cover threads which extend continuously from one anchor 9 to the other and which extend into the plies to form, depending on the configurations, the internal threads, the external threads and / or the binding threads 12. The anchor 9 is formed by at most five consecutive bypasses of a thread of the internal ply or of the external ply from the end representing the interface between the cover 16 and the anchor 9.

[0080] In a particular embodiment intended to improve the anchors 9, at least a portion of the cover wires or all of the cover wires bypass at least one wire of the internal sheet in the first five bypasses adjacent to the interface with the area without mechanical connection. In other words, the cover wire bypasses at least one of the wires of the internal sheet to fix the cover 16 to the internal layer 10. The wire of the internal sheet belongs to the first five wire bypasses made by the cover wire leaving the cover 16.

[0081] For example, the cover threads pass through the outer ply 11 and bypass at least one of the inner longitudinal threads or one of the inner transverse threads to directly fix the cover 16 to the inner layer 10. This embodiment is particularly advantageous when the cover 16 is non-woven. The thread absent from the cover 16 to form the weave defines the outer ply 11 which is preferentially woven with a thread from the inner ply to prevent the threads from being too free.

[0082] The cover 16 defines a bridge projecting from the support 15. The hole defined by the cover 16 allows the introduction of a wire element 14 or a connector. The cover deforms to facilitate the insertion of the wire element 14 or the connector. The weaving is preferably carried out to allow stretching of the cover wires which makes it possible to form a hole capable of allowing insertion. Alternatively or in addition, the cover wires are made of a material which deforms plastically to define a cover whose length is greater than the distance between the two anchors 9 in a straight line. The difference in lengths is preferably less than 30%.

[0083] Alternatively or in addition, during weaving, the hood yarn is formed longer than the equivalent yarn of the support 15. In order to maintain high weaving rates, the difference in lengths is preferably less than 30% and the number of yarns in the perpendicular direction is constant.

[0084] The absence of mechanical connection between the internal sheet 10 and the external sheet 11 makes it possible to deform the cover 16 and possibly the support 15 to define a hole, for example a tube intended for insertion.

[0085] In another embodiment, the cavity is defined by a woven support and a woven cover, i.e. the cover yarns are woven with at least one other yarn to define a weave. It is advantageous for the cover to be woven without adding any yarn other than the yarns defined above, i.e. the yarns performing the weaving with the cover yarns are chosen from internal longitudinal yarns, internal transverse yarns, external longitudinal yarns, external transverse yarns and the binding yarn. When the cover yarns are transverse yarns, the other yarns are internal and / or external longitudinal yarns. When the cover yarns are longitudinal yarns, the other yarns are internal and / or external transverse yarns. It is also possible to use the binding yarns 12 if necessary.The production of a woven hood makes it possible to form a hood which has better mechanical strength in the longitudinal direction and in the transverse direction.

[0086] Preferably, the outer sheet 11 forms the cover 16 and the inner sheet 10 forms the support 15. The dimensions of the cavity 13 are defined by the absence of the connecting threads. The dimensions of the cavity are easy to define with the loom.

[0087] Advantageously, the cavity 13 passes through in the first direction XX or in the second direction YY. When the cavity 13 is oriented in the second direction YY and more preferably when the cavity 13 passes through from a first edge 3c to a second edge 3d, the cavity 13 advantageously forms a tube intended to receive a connector, for example a carabiner with a large opening such as the carabiner marketed under the name Caritool which will receive equipment. The cover wires are advantageously internal and / or external longitudinal wires. When the cavity 13 passes through in the second direction YY, the cover wires are advantageously internal and / or external transverse wires. Such an embodiment is illustrated in [Fig. 10].

[0088] If the cavity 13 is a through cavity and extends only over a portion of the length or width of the woven layer 3, perpendicular to the two anchors 9, a step of cutting the threads of the external sheet 11 can be carried out to open the two ends of the tunnel 13 after weaving the woven layer 3. The cavity 13 can be a through cavity along the first direction XX or along the second direction YY. Cutting the threads creates a discontinuity in the threads.

[0089] The use of a through cavity extending only over a portion of the width of the woven layer 3 is advantageous for the installation and fixing of a wire element, and in particular of a wire element 14 forming a material carrier. [Fig.8] illustrates a material carrier configuration.

[0090] In the same way, it is possible to form a cavity 14 which is a blind hole as illustrated in [Fig.9]. A single cut is made to define the termination of the tunnel 13 and thus form a pocket. It is advantageous to install one end of the wire element 14 in the pocket.

[0091] In one case, the cavity 13 has a first termination which opens onto one of the first edge 3c, the second edge 3d, the first end 3a or the second end 3b. The cavity 14 is then accessed via the periphery of the woven layer 3. The wire element 14 is installed in the cavity 13 and the wire element is fixed with the support 15 and / or the cover 16 advantageously by at least one seam 18.

[0092] In a particular embodiment illustrated in [Fig. 12], the cavity 13 opens onto a first end 3a of the woven layer 3 and a strap is introduced into the cavity 13. The strap forms a strap of a device for adjusting the circumference of the woven layer 3 arranged in a ring. The strap may be a folded strap, the two ends of which are introduced into the cavity 13 and are fixed to the woven layer 3 to secure an adjustment buckle, for example a metal buckle. The strap may be the strap intended to be inserted into the adjustment buckle to adjust the circumference. The strap may be part of a clip intended to form an opening-closing system for a belt or an openable thigh strap. The strap forms the wire element 14.

[0093] In a particular embodiment, the cover 16 is non-woven and it only comprises threads which extend continuously from a first anchor 9 to a second anchor 9. The cavity 13 can be through-threaded in the first direction XX with transverse cover threads. The cavity 13 can be through-threaded in the second direction YY with longitudinal cover threads as illustrated in [Fig. 10],

[0094] When the cover threads comprise internal longitudinal threads and / or external longitudinal threads, the cover 16 spans several internal transverse threads and / or several external transverse threads of the outer layer 11. When the cover threads comprise internal transverse threads and / or external transverse threads, the cover 16 spans several internal longitudinal threads and / or external longitudinal threads of the outer layer 11. In the absence of the wire element 14, the cover 16 is deformable and movable relative to the support 15 between the two anchors 9. A non-woven cover allows for greater mobility in the longitudinal direction and in the transverse direction. [Fig. 11] illustrates a force applied to the support 15 and the cover for form the walls of the tunnel in order to increase the section of the cavity and adapt it to the shape of the connector, the wire element or the comfort / stiffening foam to be introduced.

[0095] When a cover yarn spans several other yarns, the cover yarn is arranged at a distance from said other yarns without contact. Preferably, the cover yarns have a length between the two anchors 9 which is less than 1.5 times the length of an equivalent yarn of the support 15 between the two anchors 9 and in a straight line. When a cover yarn is a transverse yarn, an equivalent yarn is a transverse yarn of the lower ply or of the upper ply which extends from a first anchor to a second anchor. The excess length of the cover yarn is obtained for example by stretching the cover yarn relative to the rest of the weaving which makes it possible to form the cavity without modifying the weaving pattern and only avoiding binding the yarns. In a particular embodiment, the support 15 is deformed with a curvature opposite to that of the cover 16 to form the cavity.

[0096] When the cover 16 is non-woven, it is advantageous for the portion of external sheet 10 forming the support 15 and delimiting the cavity 13 to comprise threads directed in the same direction as the cover threads and which intertwine the threads of the external sheet 11 and of the internal sheet 10 to provide improved mechanical strength of the cavity 14.

[0097] Figures 7, 8 and 9 illustrate different embodiments of a nonwoven cavity. In the embodiment illustrated in [Fig.7], the cover threads comprise or are constituted by the binding threads 12. Preferably, the first threads 6a intertwine the outer sheet 11 and the inner sheet 10 to mechanically bind the two sheets. First threads 6a form the inner longitudinal threads as well as the outer longitudinal threads.

[0098] In the embodiment illustrated in [Fig.8], the cover threads comprise or are constituted by the first threads 6a of the external ply 11. Preferably, the first threads 6a intertwine the external ply 11 and the internal ply 10 to mechanically bind the two plies. First threads 6a form the internal longitudinal threads as well as the external longitudinal threads. The two plies are devoid of binding threads 12.

[0099] In the embodiment illustrated in [Fig.9], the cover threads comprise or are constituted by the first threads of the internal ply 10. Preferably, the binding threads 12 and the first threads 6a intertwine the external ply 11 and the internal ply 10 to mechanically bind the two plies. First threads 6a of the internal ply 10 form the internal longitudinal threads as well as the external longitudinal threads.

[0100] To form a material carrier, it is advantageous for the woven layer 3 to have two cavities 13 which are offset from each other in the first direction XX. The wire element 14 is fixed to each of the two cavities, for example the support and / or the cover. Pre preferably the wire element 14 is fixed to the two cavities and it is free of deformation between the two cavities. More preferably the cavities comprise first wires and even more preferably the two cavities only comprise first wires 6a which continuously connect each of the two anchors 9.

[0101] In a particular embodiment illustrated in [Fig.l 1], the woven layer 3 has at least three cavities 13 and at least one of the cavities is a through cavity in the second direction YY. The at least three cavities are offset from each other in the first direction XX. The through cavity is a central cavity, that is to say it is arranged between two other cavities. The wire element 14 passes through the through cavity and is fixed to the through cavity, for example at least to one of the cover 16 and the support 15 and preferably to both. The wire element extends on either side of the central cavity to define a first strand and a second strand which are respectively fixed to a first cavity and a second cavity arranged on either side of the central cavity.Preferably, both ends of the wire element 14 and the portion in the central cavity are attached to first wires 6a and preferably to the same first wires 6a and more preferably by stitching. The equipment attached to the wire element 14 applies a weight to the first wires.

[0102] In a particular embodiment, the woven layer 3 comprises at least one cavity 13 which is a cavity that opens at the first end 3a, at the second end 3b, at the first edge 3c or at the second edge 3d. The cavity 13 may be blind or through. When the cavity 13 is through, the cavity may connect the first end 3a with the second end 3b or the first edge 3c with the second edge 3d. The cavity 13 may also connect the first end 3a with one of the first edge 3c and the second edge 3d. The cavity 13 may also connect the second end 3b with one of the first edge 3c and the second edge 3d. It is also possible for the cavity 13 to connect one end with two opposite edges or one edge with two opposite ends. It is also possible for the cavity 13 to open at two distinct locations of the same edge or the same end.

[0103] Preferably, an adjustment system 5 is installed in the cavity 13 and the cavity opens at the first end 3a. The adjustment system 5 is configured to adjust the circumference of the loop-shaped woven layer. The adjustment system 5 can adjust the circumference of the belt 1 or a leg circumference 2 depending on the woven layer 3 forms the belt 1 or a leg circumference 2. It is advantageous for the adjustment system 5 to be fixed to the ends of the woven layer. For example, the adjustment system 5 has a strap, a rope or a braid which is installed in the cavity 13. The installation of the adjustment system 5 in the cavity 13 makes it possible to improve the service life of the fastener. Preferably, the dimensions of the cavity 13 and of the part of the adjustment system 5 are chosen to form complementary elements. at least in the direction perpendicular to the axis of the cavity 13. More preferably, the adjustment system 5 is a strap and the woven layer 3 forms the woven element which slides in the loop to adjust the circumference of the woven layer 3.

[0104] A cavity 13 which opens from one of the edges advantageously receives a wire element which connects the belt 1 to one of the leg loops 2. The cavity 13 can be a cavity of the belt or of a leg loop. The wire element can connect a cavity 13 of the belt 1 to a cavity 13 of a leg loop 2. The wire element can be an elastic element.

[0105] It is also advantageous to form a cavity 13 which is a receptacle for an object which is removable from the woven layer, for example a comfort foam or a stiffener. The stiffener may be a metal part, a composite material such as a carbon part. The comfort foam and the stiffener modify the behavior of the woven layer by increasing the rigidity of the woven layer 3. Document US 2019 / 0308040 discloses a harness which defines a cavity in the belt or in a leg loop to introduce a comfort foam therein. The belt and the leg loop are formed by two fabrics which are fixed on the respective edges by two resistance straps which extend to the adjustment system to ensure the mechanical continuity of the belt and the leg loop.The formation of a cavity defined by the interlacing of the threads of the plies or a binding thread makes it possible to form a more efficient configuration of the belt or the leg loop. The mechanical strength is not provided by a possible strap or braid arranged on the edges but by the first threads 6a which are arranged in the plies. This makes it possible to define the dimension of the cavity 13 from the weaving stage which avoids an additional sewing stage. This also makes it possible to improve the capacity of the woven layer to be compressed and this makes it possible to limit the mass of the woven layer 3.

[0106] The roping harness can be made by means of the method comprising the following steps: - weaving several threads using a loom so as to form a width, the width forming at least one cavity 13; - cutting the width to form at least one woven layer 3 which comprises at least one cavity 13; - shape the woven layer 3 in the form of a ring closed by a fastener 4; - mount the woven layer so as to form a belt 1 or a leg loop 2 of the rope harness.

[0107] When weaving the width, the cavity is not necessarily accessible, particularly when the support and the cover are woven because there is continuity of the longitudinal threads. longitudinal and transverse threads. To access the at least one cavity, it is advantageous to take advantage of the step of cutting the width which makes it possible to form a cavity which opens out on at least one of the first end, the second end, the first edge and the second edge. It is also possible to carry out an additional step of cutting the external sheet of the width to cut a few longitudinal threads or a few transverse threads and thus access a cavity 13. Finally, when the cavities 13 have a non-woven cover 16, the cavity 13 is directly accessible as soon as weaving is finished, that is to say before cutting the width.

[0108] The width can be cut to define several patterns intended to form several woven layers. The different patterns can form a belt and two leg loops. The same width can be used to form belts of different sizes.

[0109] [Fig. 12] illustrates a width that has been woven and which defines five patterns intended to form leg loops 2. The patterns all have a cavity 13 that is not accessible in the width and which forms a blind hole after cutting the first edge 3c. Two patterns have a cavity 13 that is not accessible in the width and which forms a blind hole after cutting each of the first end 23a and the second end 3b. Four patterns have cavities 13 whose covers are non-woven with only first threads 6a or only threads 7a.

[0110] The width also includes a pattern intended to form a belt 1 with two cavities 13 opening at the first end 3a and at the second end 3b when cutting the width, for example for the installation of the adjustment system. The belt 1 also has two cavities opening at the second edge 3d for the installation of a wire element intended to connect the belt with the leg loops 2. The belt 1 also has a cavity obtained after cutting a few longitudinal wires 6 to form a cavity intended for the insertion of comfort foam or a stiffener.
