Description

[Technical field]

[0001] The present invention relates to a rope harness. [Background technology]

[0002] In the field of work at height, it is known to use a rope harness comprising a belt, a pair of leg ropes and a shoulder strap, the rope harness having a number of attachment points, in particular a ventral attachment point, which is designed to be attached to an attachment point such as an anchor point or to a lifeline.

[0003] The ventral attachment point can be used to attach the shoulder strap in a removable manner to make it easier for the user to don the harness, however, using the same ring to attach the shoulder strap and to suspend the user by the belt compromises the ergonomics of the suspension point and complicates the work of the rope access technician.

[0004] It is known to use two webbing straps from the leg loops to form two rings protruding from the belt. The two rings are placed substantially inside each other to form a single loop. A removable connector that connects the shoulder strap to the belt and a connector designed to be fixed to an anchor point are threaded through the two rings. These two connectors share the same loop, which has disadvantages. This configuration is widely used because it provides high multidirectional strength to the ventral suspension point, but it is less ergonomic.

[0005] From document EP 2401038 it is known to form a rope harness with two webbing rings arranged inside each other and closed by a belt. The first webbing ring forms a first loop, called the inner loop, provided with a non-detachable D-shaped connector. The connector serves as a ventral suspension point. The second webbing ring forms a second loop, called the outer loop, designed to attach a shoulder strap to the belt. The two loops are attached at substantially the same point on the belt, so that distortions between the shoulder strap and the ventral suspension point are absorbed at the same point relative to the user's centre of gravity. The inner and outer rings are formed by webbing straps extending the leg loops. However, it is clear that this configuration does not provide optimal ergonomics.

[0006] Climbing harnesses use a different structure to provide greater freedom of movement for the user between the leg loops and the belt: the belt and leg loops pass through rings located in a ventral position, but this structure is not optimal for long periods of suspended work, especially since the harness does not have shoulder straps. Summary of the Invention

[0007] One object of the present invention is to provide a rope harness having improved ergonomics of the ventral suspension points and shoulder straps as compared to prior art configurations.

[0008] This result tends to be achieved by a rope harness which: - a joining strap forming a belt, a first leg loop, a second leg loop and a leg loop link (11) connecting said first leg loop and said second leg loop; - a ring fixedly attached to the belt, through which the leg loop link passes; - a first loop fixed to said belt forming a ventral suspension point; Equipped with.

[0009] The connecting strap forms a first fold between a first strand extending from the first leg loop and a central portion, and a second fold between a second strand extending from the second leg loop and the central portion.

[0010] With the central portion secured to the belt between the first fold and the second fold, the central portion extends primarily from the first fold to the second fold in the longitudinal direction of the belt.

[0011] The ring includes the first loop, the first loop being positioned to project from the belt in the direction opposite the first leg loop and the second leg loop.

[0012] The first fold and the second fold are disposed beyond the ring on each side of the ring in the longitudinal direction.

[0013] With the ring surrounding the belt and the central portion of the interface strap, at least one stitch fixedly secures the ring, the central portion of the interface strap, and the belt.

[0014] Advantageously, said first fold and said second fold are secured to said belt by at least one stitch.

[0015] In a particular configuration, the leg loop link is secured to the belt by a belt seam and the ring is formed by a first strap having a first end secured to a second end by a resistance seam, the resistance seam withstands a first stress applied between the first loop and the leg loop, and the belt seam yields to the first stress.

[0016] In an advantageous development, the first fold and / or the second fold are fixed to the belt by fold seams and the ring is formed by a first strap having a first end fixed to a second end by resistance seams, the resistance seams withstanding a first stress applied between the first loop and the first and second leg loops and the fold seams yielding to the first stress.

[0017] In an advantageous development, the first strap is fixed to the second strap along the first loop by a first loop stitch and a first end of the first strap is fixed to a second end of the first strap by a resistance stitch, the resistance stitch withstanding a first stress applied between the second loop and the belt and the first loop stitch yielding to the first stress.

[0018] Advantageously, the leg loop link is made of a joining strap which exhibits a breaking strength in a direction connecting the first leg loop to the second leg loop which is lower than the breaking strength of the ring in a direction perpendicular to the longitudinal direction of the belt.

[0019] Other advantages and features will become more apparent from the following description of particular embodiments and implementations of the invention, given by way of non-limiting example only and illustrated in the accompanying drawings, in which: [Brief description of the drawings]

[0021] Figures 1 and 2 show a rope harness. The rope harness comprises a belt 1 and a pair of leg loops 2 having a first leg loop 2' and a second leg loop 2". The rope harness also comprises a shoulder strap 3, preferentially one end of which is detachable relative to the belt 1.

[0022] The rope harness also comprises a ventral suspension point 4 having a first loop 5 and a second loop 6. The first loop 5 is preferentially designed to receive an attachment of a shoulder strap 3, such as a shoulder strap connector 7. The second loop 6 is preferentially designed to connect to an anchor point, such as a lifeline. The second loop 6 is designed to receive a wire element, a suspension connector 8, or any other element allowing suspension of the harness.

[0023] The ventral suspension point 4 is also referred to as the umbilical suspension point. The ventral suspension point 4 can support a user attached to a harness and suspended by the harness. The ventral suspension point 4 is disposed in the midsagittal plane and is located near the user's umbilicus.

[0024] The belt 1 has a belt strap extending in a longitudinal direction and defining a circumference of the belt 1. The belt strap has a length greater than its width, which is itself greater than its thickness. The belt 1 has an inner surface designed to face and preferably contact the user, and an opposite outer surface.

[0025] The ventral suspension point 4 has a first strap 9. The first strap 9 is fastened to the belt 1 by, for example, a stitch, thereby securing the ventral suspension point 4 to the belt. The first strap 9 forms a ring 10 around the belt 1. In other words, the belt 1 passes through the ring 10.

[0026] The ventral suspension point 4 has a first loop 5 and a second loop 6 that are separate from each other. The first loop 5 and the second loop 6 are located inside a ring 10. Because the first loop 5 is separate from the second loop 6, an item attached to the first loop 5, such as a rope or connector, cannot move and reach the second loop 6, and vice versa.

[0027] The first loop 5 is outside the second loop 6 and the second loop 6 is outside the first loop 5. The arrangement of the two loops differs from the structure disclosed in document EP2401038, in which the outer loop is arranged around the inner loop with the two connectors arranged one above the other along the user's body axis. The connector arranged on the inner loop can only move inside the space defined by the outer loop, and forward movement of the inner loop tends to move the other connector attached to the other loop, which may be disadvantageous.

[0028] The first loop 5 and the second loop 6 are arranged in a ring 10. The first loop 5 and the second loop 6 are separate from the ring 10. By forming the ring 10 through which the belt 1 passes, it is possible to have a ventral suspension point 4 that remains firmly fixed to the belt 1 even in the event of a hard fall. This configuration allows for a reduction in constraints on other attachments, in particular other seams if applicable.

[0029] In a particularly advantageous manner, the two leg loops 2 are joined to each other by a leg loop link 11 passing through the ring 10. In an alternative embodiment, each leg loop 2 is fixed to the belt 1 independently of the ring 10, for example by specific stitching.

[0030] In the configuration of document EP2401038, a strap from the leg loop forms the ventral suspension point. The strap is fastened to the belt. The strap is wide and the seam is dimensioned to withstand any drop stress. The strap dimensions imply a certain rigidity. The use of a ring 10 formed by a strap separate from the leg loop 2 allows the width of the strap to be reduced and the fastening seam between the leg loop 2 and the belt 1 to be reduced, which improves the comfort of the connection between the leg loop 2 and the belt 1.

[0031] The first loop 5 and the second loop 6 are arranged side by side in a direction parallel to an axis passing through the outer and inner surfaces of the belt 1. In other words, the first loop 5 is designed to be located between the second loop 6 and the user. In a preferential embodiment, the first loop 5 receives a shoulder strap connector 7 that provides a mechanical connection between the shoulder strap 3 and the belt 1. The shoulder strap connector 7 may be a detachable connector. The second loop 6 can receive a hanging connector 8, which is preferably a non-detachable connector.

[0032] The first loop 5 and the second loop 6 are arranged at the attachment position of the belt 1 and the ring 10 so as to be movable relative to each other in a direction parallel to a first direction passing through the inner and outer surfaces.

[0033] The first loop 5 and the second loop 6 are attached so as to project from the belt 1 in a direction extending towards the shoulder strap 3, i.e. upwards when the user is standing. This allows a movement between the two loops and therefore between the two elements placed in the two loops, allowing a stress transfer in the belt 1. The movement of one loop relative to the other takes place in a direction passing through the outer and inner surfaces of the belt 1.

[0034] In a preferential embodiment, both the first loop 5 and the second loop 6 are pivotally mounted with respect to the belt 1. The pivot axis of each of the two loops extends in the longitudinal direction of the belt 1.

[0035] In a particularly advantageous embodiment, the ring 10 is attached to the belt 1 so as to fix the position of the ventral suspension point 4 in the longitudinal direction of the belt 1 and so as not to rotate longitudinally and perpendicularly around the belt 1. By attaching the ring 10 to the belt 1, a better functioning of the two loops 5 and 6 can be achieved.

[0036] In the particular embodiment shown in FIG. 3, the two loops 5 and 6 are formed by a single first strap 9 having two ends attached to one another to form a ring 10, the first strap 9 being shaped to define the two loops 5 and 6.

[0037] In an advantageous embodiment shown in Figures 4, 8 and 10, a first strap 9 and a second strap 12 are used to form a first loop 5 and a second loop 6. The first strap 9 forms a ring 10 that encircles the belt 1. The second strap 12 is disposed in the ring 10 so as to divide the ring 10 into the first loop 5 and the second loop 6.

[0038] The first strap 9 is separate from the strap forming the first leg loop 2' and separate from the strap forming the second leg loop 2", as is the second strap 12. The second strap 12 is secured to the first strap 9, preferably by a stitch, to define two loops.

[0039] A second strap 12 separates the first loop 5 and the second loop 6. The first strap 9 and the second strap 12 are advantageously fixed to the belt 1. The second strap 12 is placed inside a ring 10 to separate the two spaces forming the two loops 5 and 6.

[0040] The first loop 5 is not located inside the second loop 6, and vice versa. Preferentially, each loop has a first end fixed to the belt 1, which makes it easier for distortions of the belt 1 to be absorbed. More preferentially, each loop has a second end fixed to the belt 1. As each of the loops is separate from the other, an item located in the first loop 5 cannot move towards the second loop 6, and vice versa.

[0041] The first loop 5 and the second loop 6 are arranged to protrude from the belt 1 in the direction of the shoulder strap 3 .

[0042] In a preferential manner, the closure of the ring 10 by the seam joining the two opposing ends of the first strap 9 is separate from the seam that provides its attachment to the belt 1. This causes the seam that closes the ring 10 and the seam that attaches the ring 10 to the belt 1 to function in a different manner.

[0043] In a preferential embodiment, the two ends of the first strap 9 are fixed to each other to close the ring 10, thereby forming all or part of the first loop 5 or the second loop 6, and more preferentially at least part of the second loop 6. The doubling of the thickness increases the rigidity of the loop and makes it easier to handle.

[0044] It is advantageous for the overlap length between the two ends of the first strap 9 to represent at least 30% of the length of the second loop 6, preferably the distance separating the two attachment points to the belt 1. More preferentially, the overlap length represents at least 50% of the length of the second loop 6, or even more than 70% of the length of the second loop 6.

[0045] It is particularly advantageous for the second strap 12 to form the bent part of the second loop 6, i.e. the part designed to receive the shoulder strap connector 7. The second strap 12 prevents the first strap 9 from being worn. It is preferred that the second strap 12 has a single end which is fixedly attached to the belt 1. Directly attached to the belt means an attachment in which a part of the second strap is fixedly placed relative to a part of the belt 1. The second strap 12 may be in direct contact with the belt 1 or may be spaced apart, for example by the leg loop link 11. The fastening is preferentially obtained by a stitched seam. Here, a sewing thread may pass through the second strap 12 and the belt 1, and then through the leg loop link 11 and preferentially through the first strap 9. The fastening of only one end of the second strap 12 to the belt 1 ensures that the first strap 9 and the belt 1 are stressed when the connector wants to leave the belt 1. This also facilitates the formation of the second loop 6. Possibly also the sewing operation.

[0046] In a preferential embodiment, the overlap region between the two ends of the first strap 9 has an attachment, e.g., a resistance seam 14, that extends continuously or nearly continuously over the entire overlap length to prevent a connector or wire element from being placed between the two strands of the first strap 9, thereby preventing the formation of an additional loop.

[0047] It is also advantageous for the attachments between the belt 1 and the first strap 9, and between the belt 1 and the second strap 12, to extend continuously or nearly continuously, thereby preventing the placement of connectors or wire elements between the belt 1 and each of the first strap 9 and second strap 12, which would otherwise cause further loops to be formed.

[0048] It is also advantageous for the attachment between the second strap 12 and the first strap 9, for example by the first loop seam 13, to extend continuously or nearly continuously, thereby preventing the placement of connectors or wire elements between the belt 1 and each of the first strap 9 and second strap 12, which would otherwise create additional loops.

[0049] These configurations prevent the attachments from functioning in an adverse manner, in particular from peeling, when the attachments are seams, especially if the ventral suspension points 4 are subjected to high stresses.

[0050] If the attachment between the first strap 9 and the second strap 12 were to yield, the connector(s) and / or wire element(s) located in the first loop 5 and / or the second loop 6 would remain firmly secured to the ring 10 and therefore to the belt 1. The same is true if the attachment between the belt 1 and the first strap 9 were to break.

[0051] This construction is advantageous since the ring 10 maintains the fastening of the various elements to the belt 1. Thus, by selecting a ring 10 that exhibits selected mechanical properties to withstand a given stress, the size of the ventral suspension point 4 can be reduced. This makes it possible, for example, to select the thickness, width, material and configuration of the attachment that closes the ring 10 on the first strap 9.

[0052] The attachment parts between the belt 1 and the first strap 9, the attachment parts between the belt 1 and the second strap 12, and the attachment parts between the first strap 9 and the second strap 12 can be selected to have low performance. Also, the second strap 12 can be selected to have lower performance than the first strap 9.

[0053] In a preferred embodiment, the first loop 5 receives the attachment of the shoulder strap 3 and the second loop 6 receives the attachment to an anchor point, for example a lifeline. The first loop 5 is at least partially covered by a second strap 12. More preferentially, the attachment between the first strap 9 and the second strap 12 is obtained by a sewn seam.

[0054] When a stress is applied between the first loop 5 and the second loop 6, the first loop seams 13 along the first loop 5 between the first strap 9 and the second strap 12 peel off. These first loop seams 13 are advantageously configured to yield when subjected to a first threshold stress equal to the maximum permissible stress, but less than the stress that would cause the ring 10 to break. Above this first threshold stress, the suspension point can no longer be used. In other words, the first strap 9 is fixed to the second strap 12 along the first loop 5 by the first loop seams 13, and a first end of the first strap 9 is fixed to a second end of the first strap 9 by a resistance seam 14. The resistance seam 14 resists a first stress applied between the second loop 6 and the belt 1. The first loop seams 13 yield to this first stress.

[0055] Thus, upon noticing a break in the stitching thread forming the link along the first loop 5 between the first strap 9 and the second strap 12, the user knows that the harness is no longer usable. The stitching thread acts as an indicator that the harness has been stressed beyond its maximum allowable stress.

[0056] The same is true for the seam thread forming the attachment between the ring 10 and the belt 1. For example, the first strap 9 is fixed to the belt 1 by a belt seam 15, and a first end of the first strap 9 is fixed to a second end of the first strap 9 by a resistance seam 14. The resistance seam 14 resists a first stress applied between the second loop 6 and the belt 1, and the belt seam 15 yields to this first stress. The same is true if the belt seam 15 secures the belt 1 and the first strap 9 to each other, if the belt seam 15 secures the belt 1 and the second strap 12 to each other, or if the belt seam 15 secures the belt 1 and the first strap 9 and the second strap 12 to each other.

[0057] In the embodiment of Fig. 4, the second strap 12 is placed against the outer surface of the belt 1, but as shown in Fig. 5, the second strap 12 can be placed against the inner surface of the belt 1 with a very similar function. The mechanical performance of the ventral suspension point 4 remains almost the same whether the second strap 12 is placed on one side of the belt 1 or on the other side. On the other hand, attaching the second strap 12 to the belt 1 ensures better absorption of distortions by the belt 1 compared to when the second strap 12 is attached to the second loop 6 and the second loop 6 is closed.

[0058] In an alternative embodiment, the second strap 12 has an elongation to break that is lower than the elongation to break of the attachment portion. The second strap 12 breaks at the separation region between the first loop 5 and the second loop 6 when subjected to a large stress. Noticing the break in the second strap 12 is an indication of a stress exceeding a threshold value.

[0059] It is advantageous to form the second loop 6 by the two ends of the first strap 9, since in the event of severe stress, e.g. a fall, the attachment between the two ends works better and thus provides better breaking strength.

[0060] In the embodiment shown in figures 6 and 7, the second strap 12 is arranged in the second loop 6. The first loop 5 is closed by a first loop seam 13 and serves as an indicator that will yield if the suspension point is subjected to a large stress. It is also possible to break the second strap 12. However, this embodiment is less advantageous than the embodiment of figures 4 and 5, since it is more difficult to monitor the breaking stress of the indicator. Here too, the second strap 12 can be arranged on one side of the belt 1 or on the other side.

[0061] Figures 7 and 8 show an embodiment in which a second strap 12 is used, but which does not provide a separation between the two loops. This embodiment is less advantageous than the previous one due to the fact that the closure of the loops is performed by at least one stitch, preferably a stitch at the end of each loop. This embodiment is less advantageous because the separation between the loops is not achieved very well in time due to the high stress on the stitches.

[0062] The first strap 9 forms a ring 10 which encircles the belt 1. Preferentially, the leg loop link 11 passes through the ring 10. More preferentially, the leg loop link 11 is fixed to the belt 1 by the same stitch as the first strap 9 and possibly the second strap 12.

[0063] Preferentially, the first loop 5 and the second loop 6 are arranged facing each other in a direction perpendicular to the outer surface of the belt 1. The two loops penetrate the belt 1 in the longitudinal direction.

[0064] The use of a leg loop link 11 connecting the two leg loops 2 and passing through the ring 10 is highly advantageous as it provides a mechanical connection between the leg loop 2 and the belt 1 and relaxes the technical constraints on the attachment between the leg loop 2 and the belt 1.

[0065] The ventral suspension point 4 may have a first loop 5 and a second loop 6. However, as an alternative, the suspension point may have only the first loop 5 or only the second loop 6, as shown in FIG.

[0066] In the embodiment shown in FIG. 10, the ventral suspension point 4 defines three loops, including a further loop located within the first loop 5. The further loop is formed by the second strap 12, preferentially utilizing a portion of the second strap 12 that separates the first loop 5 from the second loop 6. In a preferential manner, the shoulder strap connector 7 is located outside the further loop, within the first loop 5. More preferentially, the shoulder strap connector 7 is detachable from the first loop 5. The shoulder strap connector 7 forms a connecting link between the shoulder strap 3 and the belt 1.

[0067] It may be advantageous to place one or more detachable connectors in the further loop. The second loop 6 is used to attach the harness to an anchor point.

[0068] Professional harnesses designed for working at height typically have a ventral suspension point located opposite the user's navel. This configuration facilitates the installation of various equipment used during prolonged suspension. This is why the configuration of harnesses designed for working at height differs from mountaineering harnesses, which are commonly referred to as "sports harnesses."

[0069] In prior art work at height harness configurations, the webbing straps forming the leg loop links are secured to the belt and form a loop or loops that define the ventral suspension point, and therefore the performance of the leg loop straps is selected to withstand the stresses of the ventral suspension point.

[0070] Traditionally, the loops at the ventral suspension point are formed using a wide strap that extends to the two leg loops. To provide strength in the event of a fall, it is necessary to provide a seam over a large surface area between each of the webbing strands and the belt. The prior art configuration means that the inclination of the leg loop link from the ventral suspension point 4 to the leg loop 2 is large. Such a configuration limits the comfort of the user, especially at thigh level, when the user is suspended in the harness.

[0071] To improve the user's comfort around the ventral suspension point 4 without overcomplicating the manufacture of the rope harness, it is advantageous to use a joining strap joining the first leg loop to the second leg loop. The joining strap passes through a ring 10, which ensures that the joining strap remains firmly attached to the belt 1 at all times.

[0072] The connection strap defines folds 16, including a first fold 16' between a central portion of the connection strap and a first strand extending from a first leg loop 2'. The connection strap defines a second fold 16" between a central portion of the connection strap and a second strand extending from a second leg loop. The first fold is separated from the second fold by a ring 10. The two strands are attached to the belt 1 at a greater distance apart than prior art configurations.

[0073] In a preferential manner, the first fold and the second fold are fixedly attached to the belt 1 by at least one stitch. Advantageously, the central part of the connection strap is fixedly attached to the belt 1, so that the belt 1 and the central part deform in the longitudinal direction of the belt 1 and in the transverse direction of the belt 1 in the same manner.

[0074] The first fold 16' and the second fold 16'' are separated in the longitudinal direction of the belt 1 by a ring.

[0075] In a preferential embodiment, the first fold 16' and / or the second fold 16" are attached to the belt 1 by a fold seam 17. The ring 10 is formed by a first strap 9, the first end of which is attached to the second end by a resistance seam 14. The resistance seam 14 withstands a first stress applied between the first loop 5 and the leg loop 2. The fold seam 17 yields to this first stress.

[0076] Advantageously, the leg loop link 11 is attached to the belt 1 by a belt seam 15. The ring 10 is formed by a first strap 9, the first end of which is attached to the second end by a resistance seam 14. The resistance seam 14 withstands a first stress applied between the first loop 5 and the leg loop 2. The belt seam 15 yields to this first stress.

[0077] By using belt seams 15 and / or fold seams 17 that are less strong than resistance seams 14, an indication of severe stress on the harness is obtained. The first stress may indicate the maximum stress that can be tolerated on the harness. If the harness is subjected to a stress higher than a threshold, the fold seams 17 and / or belt seams 15 will yield. The yielded seams act as an indicator.

[0078] By placing the leg loop link 11 inside the ring 10 and separating it from the loop designed to be attached to the anchor point, the mechanical behavior of the strap forming the link between the leg loop 2 and the ventral suspension point 4 can be modified. The wider the first strap 9 forming the ring, the greater the strength the ventral suspension point 4 can have, provided other parameters remain unchanged. However, if the strap extends up to the leg loop 2, this reduces the practicality of the loop and limits the comfort of the user of the leg loop link.

[0079] It is advantageous to use narrower straps to form the leg loop links 11 than the straps of the prior art, in order to improve the comfort of the latter. In particular, it is advantageous to use straps which are narrower and / or thinner than the straps forming the belt 1. Furthermore, it is also possible to use straps with a higher flexibility, which generally corresponds to a strap with a lower elongation at break, if other parameters, in particular costs, are not adversely affected.

[0080] In a preferential embodiment, between the first fold 16' and the second fold 16", the leg loop link 11 extends mainly or solely in the longitudinal direction of the belt 1, and the leg loop link 11 is firmly attached to the belt 1. The leg loop link 11 and the belt 1 deform in a similar manner, so that the mechanical function between the leg loop link 11 and the belt 1 becomes more homogenous.
