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, the adjustment system is formed by two elements which are commonly an adjustment buckle and an adjustment strap. The adjustment strap passes through the adjustment buckle and is locked in such a way as to define the value of the circumference. The two elements of the adjustment system are connected to each other by one or more resistance straps which ensure the mechanical resistance of the belt in the event of a fall.

[0004] It is known to make a belt or a leg loop with a single strap of constant and large width. The greater the width of the strap, the lower the pressure between the strap and the user in the event of a fall, which reduces the risk of injury. However, the use of a strap with a constant and large width is not very practical and / or is not very comfortable because a compromise must be found between the size and the contact surface. The stiffness of the strap limits the comfort of use.

[0005] In order to increase comfort, comfort foam can be installed between the strap and the user. The comfort foam extends over almost the entire circumference of the belt to connect the two elements of the adjustment system. The width of the strap is defined to withstand the forces of the fall. The strap is arranged substantially in the middle of the width of the comfort foam. The comfort foam distributes the pressure force applied by the strap on the user's body. A good compromise must be found between the width of the strap and the characteristics of the comfort foam, which are in particular the width, the thickness and the stiffness, to provide good comfort when the harness is worn. One embodiment is illustrated in documents EP0736310. It is also known to preform the comfort foam in order to define preferential deformation zones.

[0006] It has been proposed to use thin straps or cords made of strong material which are arranged in a substantially uniform manner across the entire width of a comfort foam or a moderately rigid textile support. The straps are attached to the support which defines the belt so that, during a fall, the forces experienced by the multiple straps / cords are transferred more uniformly to the user's body by means of the textile support. However, this configuration is time-consuming to implement and expensive because the multiple straps / cords must be arranged on the textile support and then attached according to a predefined pattern so that the tensioning of the straps / cords is substantially identical across the entire surface of the comfort foam during a fall.

[0007] According to another embodiment, the belt is formed by a strap, the weft thread is removed in a portion of the strap so as to free the warp threads relative to each other in the direction perpendicular to the longitudinal axis of the warp threads. The warp threads are spaced from each other to locally increase the width of the belt. The warp threads are blocked relative to each other by means of a support, by gluing or by sewing. Such teaching is present in document EPI834543.

[0008] It has also been known from document US2016 / 0375278 whose belt is formed by a strap having three series of warp threads which extend in the longitudinal direction of the strap. A first series of warp threads extends continuously from one end to the other to ensure technical resistance while the other two series of warp threads are removed at specific locations between the two ends so as to limit the bulk. Such a belt is complicated to implement and the compromise between comfort and compactness is perfectible. The belt being formed by a strap, has a symmetrical shape with respect to a longitudinal axis which does not represent the best adaptation to the morphology of the user. Subject of the invention

[0009] An object of the invention is to provide a harness which presents a better compromise between its size and its comfort.

[0010] According to one aspect of the invention, the roping harness comprises a belt, a pair of leg loops, a woven layer shaped into a ring and forming one of the belt and at least one leg loop and a closure closing the ring by fixing a first end of the woven layer with a second opposite end in a first direction.

[0011] The woven layer has a weave extending continuously from the first end to the second end and from a first edge to a second edge in a second direction perpendicular to the first direction.

[0012] The woven layer comprises longitudinal yarns and transverse yarns woven together, the longitudinal yarns comprising first yarns extending continuously from the first end to the second end to provide mechanical strength of the ring.

[0013] The weave defines a plurality of transverse strips which are woven and arranged adjacent in the first direction, the adjacent transverse strips of each pair of adjacent transverse strips having different mechanical properties.

[0014] The harness is remarkable in that the first threads have a constant texture from the first end to the second end; and in that each transverse strip has a constant texture of the transverse threads from the first edge to the second edge.

[0015] Advantageously, the plurality of transverse strips comprises at least a first transverse strip and a second transverse strip offset in the first direction and differing by a difference in chemical composition of the transverse threads.

[0016] In a particular configuration, the first transverse strip and the second transverse strip are woven with the same weaving pattern from the first edge to the second edge.

[0017] In an advantageous development, the first transverse strip is more rigid than the second transverse strip in the second direction, the transverse wires of the first transverse strip having a different nature and / or a different section from the transverse wires of the second transverse strip.

[0018] Preferably, the plurality of transverse strips comprises a hinge zone arranged between two transverse strips in the first direction, the hinge zone extending from the first edge to the second edge and forming a hinge in privileged bending between two transverse strips in response to a force perpendicular to the first direction and to the second direction.

[0019] According to one embodiment, the harness comprises a first woven longitudinal strip consisting of the first threads and transverse threads and a first additional longitudinal strip woven from at least a portion of the transverse threads and first additional threads, the first additional threads extending in the first direction over a portion of the distance between the first end and the second end.

[0020] In an advantageous development, the first longitudinal strip and the first additional longitudinal strip are differentiated by a difference in chemical composition between the first threads and the first additional threads.

[0021] Preferably, the first threads have a breaking strength greater than a breaking strength of the first additional threads.

[0022] In another advantageous development, the woven layer comprises at least one folded portion where two portions of the woven layer are folded over each other to define a fold line extending mainly in the first direction.

[0023] Preferably, the first additional longitudinal strip is folded over the first longitudinal strip, the fold line being misaligned with respect to the longitudinal direction by at least 5°.

[0024] Advantageously, one end of the fold line is on the interface between the first longitudinal strip and the first additional longitudinal strip.

[0025] In a particular embodiment, the first end is fixed to the second end by at least one seam extending in the second direction, the at least one seam fixing together the two ends of the first threads.

[0026] In another preferred development, the closure is an adjustment system configured to close and adjust the circumference of said ring and / or an opening-closing system configured to open and close the ring, the adjustment system and / or the opening-closing system is attached exclusively to the first wires.

[0027] Advantageously, the adjustment system is provided with a second loop element and a strap, the strap being intended to pass through the second loop element to fix a circumference of the ring. The second transverse strip forms one of the ends of the woven layer, the second transverse strip being a folded area which forms the strap of the adjustment system.

[0028] In a particular development, the adjustment system is provided with a second loop element and a strap, the strap being intended to pass through the second loop element to fix a circumference of the ring. The second transverse strip forms one of the ends of the woven layer, the second transverse strip being a folded area which is folded over it in the first direction to define a hole, the loop passing through the hole.

[0029] Preferably, the first sections have increased bending strength compared to the second section, the bending strength being measured perpendicular to the first direction. The first sections have stiffer cross-strands than the cross-strands of the second section. Alternatively, the first sections have increased comfort compared to the second section, the first sections having thicker cross-strands than the cross-strands of the second section.

[0030] In an advantageous embodiment, the second section has a water vapor permeability greater than the water vapor permeability of the first sections.

[0031] In another advantageous development, the two transverse bands of each group of two adjacent transverse bands are differentiated by at least one of the characteristics chosen from: - a difference in chemical composition and / or diameter of the transverse threads, - a difference in texture of the transverse threads, - a difference in weaving pattern between the transverse threads and the longitudinal threads.

[0032] Preferably, the woven material has a wide portion having a greater width than a narrow portion, the wide portion and the narrow portion being arranged consecutively in the first direction, the width being measured in the second direction. The narrow portion is formed by a folded zone in which the woven layer is folded locally along a fold line extending mainly in the first direction so as to reduce its effective width in said second direction, the number of first threads being constant between the narrow portion and the wide portion.

[0033] Advantageously, the at least one folded zone comprises a support zone covered by an overlap zone which are held together fixedly by a seam.

[0034] In a particular development, the at least one narrow zone comprises at least two transverse bands.

[0035] The invention also relates to a method of manufacturing a roping harness which is easier to produce than the configurations of the prior art to form a harness which presents a better compromise between comfort and bulk.

[0036] This result is achieved by means of a method of manufacturing a rope harness comprising the following steps: - providing a woven web comprising at least one warp band and a plurality of weft bands or at least one weft band and a plurality of warp bands, a weft band extending in the direction of a weft and comprising a set of weft threads and a warp band extending in the direction of a warp and comprising a set of warp threads, in which each weft band is distinguished from the adjacent weft band by at least one difference in the texture of the weft threads, the nature of the weft threads or a diameter of the weft threads, in which each warp band is distinguished from the adjacent warp band by at least one difference in the texture of the warp threads, the nature of the warp threads or a diameter of the warp threads; - cutting the width to form at least one woven layer representative of a belt or at least one thigh loop, the plurality of weft bands or the plurality of warp bands forming a plurality of transverse bands extending according to a second direction from a first edge to a second edge, the at least one warp or weft strip forming at least one longitudinal strip extending in a first direction from a first end to a second end, each transverse strip having a constant texture of transverse threads from the first edge to the second edge; - shape the woven layer into a ring; - closing the ring by a closure fixed at the first end and at the second end, the longitudinal threads comprising first threads extending continuously from the first end to the second end and having a constant texture from the first end to the second end.

[0044] [Fig.7]: [Fig.7] schematically illustrates a width intended to be cut to form one or more woven layers representing a belt or a thigh circumference. Description of the embodiments

[0045] Figures 1 to 5 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 second end 3b are opposite in direction XX.

[0046] Depending on the embodiments, the closure 4 is selected from an adjustment system 5 configured to adjust the circumference of the ring-shaped woven layer, 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 that are also opening-closing systems.

[0047] 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.

[0048] The woven layer 3 comprises longitudinal threads 6 and transverse threads 7 woven together to form a weave. The longitudinal threads 6 extend in the first direction XX while the transverse threads 7 extend in the second direction YY perpendicular to the first direction XX. The weave extends continuously from the first end 3a to the second end 3b opposite in the first direction XX. The weave extends continuously from the first edge 3c to the second edge 3d opposite in the second direction YY.

[0049] 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 to ensure the mechanical integrity of the ring in the closed position in the event of a fall.

[0050] 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.

[0051] 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 layer 3 has a first zone whose longitudinal woven yarns 6 are only first yarns 6a. 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 yarns 6a which ensures the mechanical strength of the woven layer 3 in the direction XX in the event of a fall in order to ensure the integrity of the ring.

[0052] 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.

[0053] To improve comfort when the user is suspended in his harness, it is advantageous to have a mechanically active contact surface that is as large as possible 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.

[0054] The woven layer 3 has a thickness which is defined by the diameters of the threads used and the weave(s) applied.

[0055] The woven layer 3 preferably has a wide portion 3f and a narrow portion 3e, the wide portion 3f having a greater width than the narrow portion 3e. The wide portion 3f and the narrow portion 3e are woven. The wide portion 3f and the narrow portion 3e are offset along the first direction XX. The width is measured along the second direction YY. The variation in width of the woven layer 3 makes it possible to better adapt the shape of the belt 1 or the thigh circumference 2 to the morphology of the user. The continuous weaving along the directions XX and YY ensures better distribution of pressure when the user is suspended. It is preferable to have a wide portion 3f in the dorsal part of the belt 1 or in the rear part of the thighs 2. On the other hand, a narrow portion 3e is preferred in the abdominal part so as not to hinder a user who leans forward. The front part of the Leg loops 2 can also be associated with a narrower area because the force recovery is moderate. This adaptation of the shapes makes it possible to lighten the harness.

[0056] To withstand significant forces in the event of a fall, the aim is to stress a large number of first threads 6a. In the configurations of the prior art, such a result is obtained by using a single strap of great width. The wider the strap, the greater the number of first threads 6a to be stressed. The width is much greater than what is necessary to withstand the forces of a fall, but this makes it possible to reduce the pressure forces on the user. In return, the adjustment system is more voluminous.

[0057] In order to provide a woven layer 3 which presents a better compromise between the resistance in the first direction XX and the comfort represented by the width in the second direction YY, the woven layer 3 preferably has at least one narrow portion 3e and a wide portion 3f. The narrow portion 3e is formed by at least one fold. The fold is defined by a fold line 8 which represents an edge of the narrow zone 3e where the woven layer 3 is folded over it. The fold line 8 extends mainly in the first direction XX so as to make the first threads 6a work effectively during a fall. Preferably the fold line 8 also has a component in the second direction YY.

[0058] When the fold line 8 is parallel to the second direction YY or almost parallel to the second direction YY, the mechanical stress on the folded area causes the two portions of the first wires 6 arranged on either side of the fold to work differently.

[0059] The folded area is formed from the woven layer 3 which defines a support portion 3' and a covering portion 3” as illustrated in [Fig.4]. The covering portion 3” is folded over the support portion 3' as illustrated in [Fig.5]. The support portion 3” and the covering portion 3' have one or more first threads 6a in common. The covering of the support portion 3' by the covering portion 3” makes it possible to maintain the number of first threads 6a while reducing the effective width of the woven layer 3 which will be stressed in the event of a fall. By folding and locally increasing the thickness, it is possible to make a large number of first threads 6a work as is the case in the dorsal part of the belt 1 or the rear part of the thigh loop 2.

[0060] The covering portion 3” and the support portion 3' have second wires 7a in common, which allows for better transfer of forces in the folded part. The use of first wires 6a and second wires 7a common between the covering portion 3” and the support portion 3' ensures better transfer of forces.

[0061] The use of first threads 6a which connect the two ends 3a and 3b and which pass through the wide zone 3f and the narrow zone 3e makes it possible to provide a woven layer 3 which adapts better to the morphology of the user while being able to have a large number of first threads 6a. The wide zone 3f and the narrow zone 3e have an identical number of first threads 6a. The second threads 7a which connect the two thicknesses ensure a good transfer of forces between the two folded layers while the two thicknesses ensure greater rigidity. It is advantageous for the number of threads / cm to be constant from the first end to the first end, for each given group of consecutive first threads, for example at least ten first threads. It is also advantageous for the number of threads / cm in the portion containing the first threads to be constant from one end to the other in the YY direction.

[0062] The increase in thickness makes it possible to have a local increase in the rigidity of the woven layer 3, which can be advantageous near an adjustment system or an opening-closing system in order to facilitate its use, in particular with gloves.

[0063] The narrow zone 3e and the wide zone 3f are crossed by the same number of first threads 6a. They have the same performance or substantially the same mechanical performance in the first direction XX. The distribution of the first threads 6a over at least two thicknesses of the woven layer 3a makes it possible to use a large number of first threads 6a, which makes it possible, for example, to reduce the cross-section of the first threads 6a and / or to reduce the thickness of the comfort foam. In one case, the belt 1 and / or the thigh loop 2 is devoid of comfort foam. The reduction in the cross-section of the threads makes it possible to improve the flexibility of the woven layer 3.

[0064] Folding is a simple operation to carry out and well mastered, which makes it possible to form a rope harness economically.

[0065] Preferably, the longitudinal threads 6 comprise the first threads 6a as well as first additional threads 6b. The first additional threads 6b do not extend continuously from the first end 3a to the second end 3b and / or are not fixed at at least one of their ends with the closure 4. The first additional threads 6b are connected to the first threads 6a by the second threads 7a to ensure mechanical cohesion from the first edge 3c to the second edge 3d.

[0066] During a fall, the first additional threads 6b are not stressed as much as the first threads 6a and they cannot be used to ensure the mechanical integrity of the harness. The first additional threads 6b are woven with the second threads 7a so as to form at least one woven zone which extends beyond the first threads in the wide zone 3b. This at least one woven zone makes it possible to improve comfort by slightly absorbing the forces and increasing the contact zone with the user.

[0067] The first additional wires 6b are preferably made of a material different from the material forming the first wires 6a. Preferably, the first wires 6a form a single zone extending continuously along the second direction YY. The first additional yarns 6b form one or two woven zones on one side or on each side of the zone constituted by the first yarns 6a along the second direction YY.

[0068] Preferably, the fold line 8 defines with the first direction XX an angle less than 30°. More preferably, the fold line 8 defines an angle less than 20°. The smaller the angle, the closer the behaviors between the first folded wires 6a and the first unfolded wires 6a are. Advantageously, the fold line 8 defines an angle at least equal to 5° in order to have a good compromise between the length of the narrow zone 3e along the first direction XX and the overlap surface 3” along the direction Y Y.

[0069] Preferably, each first wire 6a is discontinuous from the other first wires 6a and each second wire 7a is discontinuous from the other second wires 7a. In other words, the first wires 6a and the second wires 7a are not formed by a single wire. The first wires 6a and the second wires 7a are cut at their two ends. The second wires 7a provide the transverse mechanical connection between the first wires 6a by mechanically connecting all the first wires 6a and more preferably all the longitudinal wires.

[0070] The woven layer may be formed by cutting a fabric or webbing, for example by laser cutting. The fabric or webbing has warp and weft threads that are woven together in a predefined two-dimensional or three-dimensional pattern. The fabric or webbing is then cut in a predetermined pattern to form the woven layer 3 with the correct positioning of the first threads 6a and the first additional threads 6b if applicable.

[0071] Following the cutting of the fabric or the strap, the first threads 6a are independent of each other in response to a point stress in the longitudinal direction XX. The second threads 7a are independent of each other in response to a point stress in the second direction YY. The cutting of the initial material to form the woven layer 3 may prevent determining which thread is a weft thread and which thread is a warp thread.

[0072] The independence of the second threads 7a along the second direction YY makes it possible to have greater flexibility of the woven material compared to a fabric where the first threads or the second threads correspond to the same thread.

[0073] It is advantageous for the narrow portion 3e to have a width that is less than the width of the wide portion 3f by at least 30%. In a particular embodiment illustrated in Figures 4 and 5, a narrow portion 3e is formed by a single fold of the woven layer 3. It is possible to provide that the narrow portion 3e or another narrow portion 3a is formed by two folds with two fold lines 8. The choice between a single 8 fold line or two 8 fold lines depends on the shape of the narrow area 3rd and the ease of making cuts and folds.

[0074] The narrow portion 3e formed by at least one fold makes it possible to have a part of the woven layer 3 which covers another part of the woven layer 3 in the direction of the thickness which is perpendicular to the first direction XX and to the second direction YY. In order to have good work of the first threads 6a, it is advantageous for the first threads 6a of the two thicknesses of the narrow zone 3e to be misaligned as illustrated in [Fig.5]. The narrow zone 3e has at least one seam 9 which fixes the misalignment between the first threads 6a. In other words, it is not advantageous to want to make a second fold in the continuity of the first fold so that the first threads 6a are arranged parallel. The two consecutive folds brought together in the direction XX will create an asymmetry in the forces applied between the different first threads 6a.

[0075] In a particularly advantageous configuration, the narrow zone 3e is sufficiently narrow to form a strap capable of passing through a conventional buckle of an adjustment system 5. This embodiment is particularly advantageous because the first threads 6a of the woven layer 3 form the strap of the first strap element 5a, i.e. the part which passes through the buckle and moves inside the buckle to define the circumference of the ring and locks in the buckle to fix the circumference of the ring.

[0076] This embodiment is particularly advantageous because it avoids fixing a strap on the end of the woven layer 3 so as to achieve mechanical continuity between the woven layer 3 and the first strap element 5a. The force transfer is better applied. The woven layer 3 then forms part of the adjustment system 5.

[0077] In a preferred embodiment, the end of the woven layer 3 intended to receive the second loop element 5b forms a narrow portion 3e. The narrow portion 3e is obtained by at least one fold line. In one case, the woven layer 3 is folded so that the width is equal or substantially equal to the width of the strap supporting the loop of the second loop element 5b. In another case, the narrow portion 3e forms a wire element such as a strap supporting the loop of the second loop element 5b. The wire element forms a ring which is closed. The ring is closed by a seam extending in the second direction YY, for example from one edge to the other. The loop of the adjustment system 5 is enclosed in the ring. In this case, the woven layer 3 forms a part of the adjustment system 5.As with the previous configuration, the folding of the woven layer 3 makes it possible to have a large contact surface with the user in the wide portion with a large number of first threads 6a, for example the dorsal part. of the harness and to keep this large number of first threads 6a in the adjustment system 5. Near the median sagittal plane, the width of the woven layer 3 decreases so as not to hinder the user who bends forward.

[0078] In order to provide an improved compromise between comfort and ease of adjustment, it is advantageous for both ends of the woven layer 3 to be narrow portions 3e. A first narrow portion 3e is intended for fixing or forming the strap of the first strap element 5a and a second narrow portion 3e is intended for fixing the second buckle element 5b or for fixing the buckle. This embodiment is particularly advantageous because it makes it possible to have a harness whose mass is reduced.

[0079] It is particularly advantageous that the folded areas, i.e. the areas where two thicknesses of the woven layer 3 overlap, are fixed to each other by at least one fixing seam 9. The use of a fixing seam 9 makes it possible to fix the position of the first threads 6a relative to each other and to form a narrow area 3e which is more rigid. The increase in rigidity makes it possible to have a more homogeneous stress on the first threads 6a in comparison with an area where the two thicknesses of woven layer 3 can deform independently of each other.

[0080] The rope harness can be produced using a production method which is simple and easy to implement.

[0081] A width of woven material is provided which comprises longitudinal threads 6 woven with transverse threads 7. The woven material comprises at least first threads 6a woven with second threads according to one or more predefined weaving patterns. The width may be a fabric or possibly a webbing. The first threads 6a extend in the first direction XX. The second threads 7a extend in the second direction YY. The width has a thickness. Preferably, a fabric is used which makes it possible to offer greater freedom in the shape and / or definition of the woven areas with different mechanical performances, for example differences in the threads used, in the weaving pattern used.The use of a fabric makes it possible to form one or more woven patterns arranged in a non-symmetrical manner with respect to the first direction XX or with respect to the second direction YY, which is preferential for forming several designs representative of a belt 1 and / or a thigh circumference 2 on the same width.

[0082] The width is cut into a predefined shape to define a woven layer 3 intended to form a belt 1 or a leg loop 2 of a roping harness. The weaving extends continuously from the first end 3a to the second end 3b in the first direction XX and from a first edge 3a to a second edge 3d in the second direction YY. Each first thread 6a extends continuously along the first direction XX, for example from the first strap element 5a to the second loop element 5b to achieve mechanical continuity. The second threads 7a extend continuously from the first edge 3c to the second edge 3d.

[0083] Each second wire 7a mechanically connects all the first wires 6a along the second direction YY and is discontinuous from the other second wires 7a. Each first wire 6a is discontinuous from the other first wires 6a. Each first wire 6a preferentially connects all the second wires 7a.

[0084] A portion of the woven layer 3 is folded so as to form a wide portion 3b and a narrow portion 3e. The wide portion 3f and the narrow portion 3e are woven. The wide portion 3f and the narrow portion 3e are offset along the first direction XX. The width is measured along the second direction YY.

[0085] The narrow zone 3e is obtained by folding with at least one fold line 8 extending mainly in the first direction XX. The narrow zone 3e has at least two thicknesses of the woven layer 3. The two thicknesses of the woven layer 3 are mechanically linked by a continuity of the first threads 6a and the second threads 7a.

[0086] A first strap element 5a and a second loop element 5b are formed, arranged at the two opposite ends of the woven layer 3 in the first direction XX and configured to adjust the circumference of said one of the belt 1 and a thigh circumference 2. Each first thread 6a extends continuously in the first direction XX from the first strap element 5a to the second loop element 5b to achieve mechanical continuity. The first threads 6a of two thicknesses of the narrow zone 3e extend from the first strap element 5a to the second loop element 5b.

[0087] When forming the width of woven material, the first threads 6a are woven with the second threads 7a so as to form a woven pattern which is representative of a belt 1 or a thigh circumference 2. The woven pattern is cut, for example by laser cutting to form the woven layer 3. Preferably, the cut pattern has the woven portion constituted by the first threads 6a and the second threads 7a as well as the additional portion(s) constituted by the first additional threads 6b and the second threads 7a woven together. The first additional threads 6b are arranged parallel to the first threads 6a. The characteristics of the first threads 6a, their number and the weaving pattern with the second threads 7a have been defined beforehand to withstand a set of stresses representative of a belt 1 or a thigh circumference 2.

[0088] The shape of the woven layer 3 and in particular of the woven pattern constituted by the first threads 6a and the second threads 7a is produced by the loom. The shape of the patterns additional patterns consisting of the first additional threads 6b and the second threads 7a is made by the same loom. All these patterns are made in the same weaving operation, that is to say by means of the same loom and in one go.

[0089] Depending on the configurations, the first threads 6a and the second threads 7a are respectively warp threads and weft threads or weft threads and warp threads.

[0090] Several patterns representative of a belt and / or a thigh loop are produced on the same width using a single loom in a single weaving operation. The width is then cut so as to delimit several woven layers 3 which are intended to form the belts 1 and / or the thigh loops 2. The same width can be subjected to several successive cutting operations to form different patterns representative of belts 1 having different lengths and / or widths and / or different patterns representative of thigh loops 2 having different lengths and / or widths.

[0091] Preferably, the woven layer 3 representative of a belt 1 or a thigh strap 2 comprises a central band having only first threads 6a in the direction XX and which extends mainly in the first direction XX. The pattern preferably comprises one or more additional zones which extend from the central band and which form at least part of an edge of the woven layer 3.

[0092] Once the width has been cut to form the woven layer, folding is carried out by defining a fold line 8. The folding makes it possible to have a reduction in the width of the woven layer 3 with mechanical continuity of the first threads 6a and the second threads 7a. The folding(s) reduce the width of the woven layer 3 and make it possible to have a substantially constant tensile strength from the first end 3a to the second end 3b.

[0093] Preferably, a sewing step is carried out on the folded area so as to fix the positions of the first threads 6a relative to each other in the first direction XX for the at least two superimposed thicknesses. This makes it possible to have a more uniform deformation between the two thicknesses of the woven layer 3 and therefore to have a more uniform stress on the first threads 6a.

[0094] In a particular embodiment, the first strap element 5a comprises a strap which is sewn to one end of the woven layer. The width of the strap corresponds to the width of the narrow zone 3e so as to stress all the first threads 6a. In another particular embodiment, the second loop element 5b comprises a strap which is sewn to one end of the woven layer 3. The width of the strap corresponds to the width of the narrow zone 3e so as to stress all the first threads 6a. Preferably, the strap is fixed by sewing. A sewing thread passes through the multiple thicknesses of the woven layer 3 fabric in the direction of the thickness. Sewing the two plies of the woven material makes it possible to fix the position of the two plies and therefore to fix the spatial configuration of the first threads 6a.

[0095] In a preferred embodiment, the covering layer 3” comprises first threads 6b and first additional threads 6b and the covering layer 3” has a shape identical to the support layer 3'. The covering layer 3” and the support layer 3' are fixed to each other by sewing threads 9. Although the covering layer 3” has first additional threads 6b, the complete covering of the support layer from one edge to the other allows for mechanical operation of the narrow zone 3e.

[0096] This configuration is particularly advantageous because it makes it possible to form a belt 1 or a thigh loop 2 which has a significant proportion of first threads 6a compared to the longitudinal threads 6. The belt 1 or the thigh loop 2 can be formed without comfort foam, which makes it possible to reduce the weight and bulk. The woven layer 3 can be made from a fabric comprising two plies, that is to say with two sets of weft threads and warp threads arranged one on top of the other. One ply ensures the mechanical strength of the woven layer 3. The other ply forms a protective layer to avoid direct contact with the first threads 6a on one face of the woven layer 3.

[0097] When the second threads 7a have a constant diameter between the narrow portion 3e and the wide portion 3b, the creation of a fold makes it possible to form a woven layer 3 which is thicker than the wide portion 3b. When the second threads 7a are identical or substantially identical between the narrow portion 3a and the wide portion 3f, the fold makes it possible to increase the rigidity of the narrow portion 3a relative to the wide portion 3f. The increase in rigidity is particularly advantageous when the first threads 6a form the strap which passes through the buckle of the adjustment system. This allows for better control in handling the strap. Where appropriate, the second fold may be formed in a material which has a lower static and / or dynamic coefficient of friction than the coefficient of friction of the first threads 6a in order to better maintain the ring in the chosen circumference.

[0098] To form the narrow portion 3e or one end of the narrow portion 3e, it is also advantageous to choose second wires 7a different from other second wires 7a so as to have a lower static and / or dynamic friction coefficient than the static and / or dynamic friction coefficient of the first wires 6a in order to better maintain the ring in the chosen circumference. The second wires 7a can also be chosen to adjust the stiffness value of the narrow portion 3e or of a part of the narrow portion 3e.

[0099] Such embodiments may be used to form the narrow portion 3e intended to receive the second loop element 5b or to hang the loop.

[0100] As an alternative or in addition to a woven layer 3 which comprises a narrow zone 3e obtained by folding, it is particularly advantageous to provide a woven layer 3 which has several woven sections arranged consecutively in the first direction XX and / or the second direction YY and which have different technical characteristics. As previously, the woven layer 3 has a weave extending continuously from the first end 3a to the second opposite end 3b in the first direction XX and from the first edge 3c to the second edge 3d in the second direction YY.

[0101] The woven layer 3 comprises longitudinal threads 6 and transverse threads 7 woven together. The longitudinal threads 6 comprise first threads 6a extending continuously from the first end 3a to the second end 3b to ensure mechanical strength of the ring.

[0102] It is particularly advantageous to provide that two adjacent zones of each pair of adjacent zones have different mechanical properties. The two adjacent zones have common longitudinal or transverse wires. The difference in mechanical properties between two adjacent zones corresponds to at least one of the characteristics chosen from: - a difference in chemical composition and / or diameter of the transverse threads for two adjacent zones offset in the first direction (XX), - a difference in chemical composition and / or diameter of the longitudinal threads for two adjacent zones offset in the second direction (YY), - a difference in the texture pattern of the transverse threads, - a difference in weaving pattern between the transverse threads and the longitudinal threads.

[0103] Preferably, two distinct adjacent zones arranged consecutively only in the first direction XX or in the second direction YY. In other words, two adjacent distinct zones share only longitudinal threads 6 or only transverse threads 7. Figures 4 and 6 illustrate a woven layer 3 which has different zones arranged one behind the other in the first direction XX or in the second direction YY. The zones 3g, 3h, 3i, 3j, 3k, 31, 3m and 3n are distinct zones arranged one behind the other in the first direction XX which can be a warp direction or a weft direction. The zones 3o and 3p are distinct zones arranged one behind the other in the second direction YY which can be a weft direction or a warp direction.

[0104] The use of at least a first zone, for example 3g and a second zone, for example 3h, arranged consecutively in the first direction XX and which are crossed by the first threads 6a allows for good transfer of forces from the first end 3a to the second end 3b while functionalizing the woven layer 3, i.e. by adapting the mechanical characteristics of the woven layer 3 to respond to specific problems. The functionalization is carried out by using different second threads 7a and / or a different weaving pattern between the first zone and the second zone.

[0105] The first zone has a first type of second yarns 7a and a first weaving pattern. The second zone has a second type of second yarns 7a and a second weaving pattern. The first type of second yarns is different from the second type of second yarns and / or the first weaving pattern is different from the second weaving pattern. For example, the different zones 3g-3n are all distinguished from the adjacent zone by a mixture of different second yarns.

[0106] The first zone is distinguished from the second zone by a difference in water permeability depending on the direction of the thickness. The water permeability is measured by means of a test according to ISO 2528 or EN ISO 12572. The difference in permeability allows for better regulation of perspiration. For example, the large zone portion 3d or 31 has a higher water permeability than the 3g or 3h zone because it is intended to have more continuous contact with the body. It must therefore be able to better wick away perspiration.

[0107] Alternatively or in addition, the first zone is distinguished from the second zone by a difference in air permeability depending on the direction of the thickness. The air permeability is measured by means of a test according to ISO 9237.

[0108] Alternatively or in addition, the first zone is distinguished from the second zone by a difference in flexural strength for a force applied in the direction of the thickness ZZ. The difference in flexural strength makes it possible to adjust the comfort of the woven layer.

[0109] Alternatively or in addition, the first zone is distinguished from the second zone by a difference in thickness which makes it possible to modulate the comfort and therefore better adapt the mechanical performance to the morphology of the user. It is advantageous to have a difference in thickness between zones 3g and 3h to better adjust the ease of use of the part involved in the manipulation of an adjustment device 5 or opening-closing device.

[0110] Alternatively or in addition, the first zone is distinguished from the second zone by a difference in elasticity along the second direction YY. The difference in elasticity makes it possible to have different displacements of the first threads 6a relative to each other along the second direction YY depending on the zone, which makes it possible to have a better adaptation of the shape of the woven layer to the morphology of the user. The 3h and 3d zones have different flexibilities to better adapt to the needs of the user suspended in the harness.

[0111] Preferably illustrated in [Fig.6], the woven layer 3 has at least three consecutive zones along the first direction XX. The at least three zones define two zones separated by a hinge zone. The weaving and / or the nature of the second threads in the hinge zone is configured to define a preferred bending along the first direction XX in response to a force along the direction ZZ. The hinge zone has a lower rigidity than the rigidity of the two adjacent zones. For example, zone 3k forms a hinge zone between zones 3j and 31.

[0112] It is advantageous to provide that the woven layer 3 has a zone of greater rigidity at each end of the woven layer 3. Preferably, the zone of greater rigidity is one of the narrow zones. More preferably, the two ends of the woven layer 3 are narrow zones 3e. For example, zones 3g and 3h have greater rigidity than zones 3j, 3k, 3m and 3n to have greater comfort in the zone which is almost continuously in contact with the body and less comfort resulting from greater rigidity in a portion where the pressure on the body is less.

[0113] When the woven layer 3 has a folded area, that is, an area that is formed by two superimposed layers of the woven layer 3, it is advantageous for the second yarns 7a of the folded area to be formed by different second yarns from the area adjacent to the folded area. It is preferable for the folded area to have second yarns 7a that have greater rigidity. For example, the second yarns used to form areas 3g, 3h, and 3i are different from the second yarns 7a used in area 3j, and they may be different from each other.

[0114] In a particular embodiment, the woven layer 3 has one end which is a folded area. The folded area has an area of ​​greater rigidity and a more flexible area which are arranged consecutively in the first direction XX. The more flexible area is intended to be folded over itself and fixed by sewing to fix the loop of the second loop element 5b or a loop of an opening-closing device. For example, the area 3g uses second threads 7a different from those of the area 3h to facilitate its folding relative to a fold line parallel to the second direction YY.

[0115] The use of a flexible zone makes it easier to fold the end of the woven layer 3 which is already a folded layer. There are then four layers of fabric superimposed on each other. For example, we seek to reduce the thickness of zone 3g compared to zone 3h.

[0116] The functionalization of the woven layer 3 by adjusting the mechanical performance of the second threads 7a or the weaving makes it possible to have a woven layer 3 of low thickness and better adapted to the needs of the user.

[0117] The modification of the second wires 7a to define the at least two zones can be obtained in different ways. The difference of second wires between the first zone and the second zone can be chosen from a different diameter, a different chemical composition or a different surface condition.

[0118] In the same zone, the second wires 7a may be identical or it may be a mixture of several wires of different natures and / or sizes.

[0119] In a particular case, the first zone is defined by second yarns 7a of a first nature, for example second yarns made of high tenacity polyamide formed by multifilaments, and the second zone is defined by a mixture of second yarns 7a of a first nature and second yarns 7a of a second nature, for example second yarns 7a of high tenacity polyamide and second yarns 7a of monofilament type.

[0120] The second yarns 7a extending in the second direction YY from the first edge 3c to the second edge 3d, the woven layer 3 defines consecutive transverse bands 3g-3n where there is a unit of the second yarns 7a. Two consecutive transverse bands can be distinguished by a difference in chemical composition of the second yarns 7a.

[0121] Preferably, the weaving pattern is identical from the first edge 3c to the second edge 3d in a given transverse band. Advantageously, the texture is constant for a given transverse band 3g-3n.

[0122] The woven layer 3 has a longitudinal strip 3o-3p which extends in the first direction XX and which has a unit in the longitudinal threads 6 used. The woven layer 3 comprises at least one first longitudinal strip 3o which is formed by all or part of the first threads 6a. When the first threads 6a are identical, the first threads 6a define only the first longitudinal strip 3o. When the first threads 6a have two different types of threads dissociated in the direction YY to provide two different mechanical behaviors, the first threads 6a define the first longitudinal strip and a second longitudinal strip.

[0123] Advantageously, the woven layer 3 has at least two distinct longitudinal strips 3o and 3p. The second longitudinal strip 3p is devoid of first threads 6a.

[0124] The longitudinal and transverse strips intersect to define distinct functional zones which have different mechanical characteristics from the immediately adjacent functional zone in the first direction XX or according to the second direction YY. The use of common longitudinal yarns 6 or common transverse yarns 7 allows for better transfer of forces while being able to adapt the performance of the woven layer 3. This avoids adding one or more layers on the woven layer 3.

[0125] The woven layer 3 is obtained from a width which comprises several distinct functional zones. The width has weft bands extending in the weft direction and / or warp bands extending in the warp direction. Preferably, in a warp band, the texture of the warp threads is constant from one end of the warp band to the other, the same warp threads are present and with the same arrangement. Preferably, in a weft band, the texture of the weft threads is constant from one end of the weft band to the other, the same weft threads are present and with the same arrangement. The width comprises at least one weft band and several warp bands or at least one warp band and several weft bands.

[0126] The warp bands cross the weft bands to define an area with precise mechanical characteristics that come from the weft and warp threads used and the weaving pattern employed. The area is preferably in the shape of a rectangle. The warp and weft threads are chosen and the weaving program of the loom is configured to form the multiple areas of the width by means of the different weft bands and warp bands.

[0127] A width is formed by means of a loom. The loom weaves the different threads which will form the longitudinal threads 6 and the transverse threads 7 according to the previously defined program. The width has zones which are distinguished from the immediately adjacent zones according to the warp direction or the weft direction by a difference in the threads used and / or in the weaving pattern.

[0128] The width is cut, for example by laser cutting, in order to form the woven layer 3 which is intended to form a belt or a thigh strap. The weft strips and the warp strips form the transverse strips and the longitudinal strips or vice versa. The weft strips and the warp strips have been defined in their dimensions and in their mechanical characteristics in order to form a woven layer having particular mechanical characteristics. The width is cut to place the weft strips and the warp strips in the expected positions for the transverse strips and the longitudinal strips or vice versa.

[0129] The loom offers great freedom in the way of forming the weft bands and the warp bands, it is even possible to form the two thigh loops using the same width. The width may include one or more patterns representative of a belt 1 and / or one or more patterns representative of a leg loop thigh 2 or a pair of thigh loops 2. The patterns can be arranged one behind the other according to the direction of the weft or the warp.

[0130] As illustrated in [Fig.7], the same width may contain belt patterns 1 having different dimensions in order to form belts adapted to different body sizes. The same may apply to thigh circumferences 2.

[0131] The width coming from weaving by a loom and in particular with a Jacquard type loom, the shapes of the zones are free which makes it possible to form, in a single operation of a loom, a width which includes patterns better adapted to the formation of several patterns representative of a belt and / or a thigh circumference which limits losses compared to the manufacture of a strap.
