Description

Technical Field

[0001] The utility model relates to a rope harness. Background Art

[0002] In the field of working at heights, it is known to use a rope harness provided with a waist belt, a pair of leg loops and shoulder straps. The rope harness has 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 a lifeline.

[0003] The ventral attachment point can be used to removably attach the shoulder straps, making it easier for the user to put on the harness. However, using the same loop to attach the shoulder straps and to suspend the user (via the waist belt) compromises the ergonomics of the suspension point, complicating the work of the rope access technician.

[0004] It is known to use two woven straps from the leg loops to form two loops protruding from the waist belt. The two loops are substantially arranged to nest within each other to form a single loop. The two loops are passed through by a removable connector that effects the connection between the shoulder straps and the waist belt, and also by a connector designed to be fixed to an anchor point. The two connectors share the same loop, which is detrimental. This configuration is widely used because it provides high multi-directional strength for the ventral suspension point, but is offset by reduced ergonomics.

[0005] From the document EP2401038, it is known to form a rope harness having two woven loops arranged to nest within each other and closed by a waist belt. The first woven loop forms a first loop called the inner loop and is provided with a non-removable D-shaped connector. This connector acts as the ventral suspension point. The second woven loop forms a second loop called the outer loop, which is designed to attach the shoulder straps to the waist belt. The two loops are substantially attached at the same position on the waist belt, such that strain absorption between the shoulder straps and the ventral suspension point occurs at the same position relative to the user's center of gravity. The inner loop and the outer loop are formed by a woven strap extending the leg loops. However, it is obvious that this configuration does not achieve optimized ergonomics.

[0006] In climbing harnesses, different structures are used to provide the user with greater freedom of movement between the leg loops and the waist belt. The waist belt and the leg loops pass through a loop located in the ventral position. However, this structure is not most suitable for working for a long time when suspended in the harness, especially when the harness is not equipped with shoulder straps. Summary of the Utility Model

[0007] An object of the utility model is to provide a rope harness which presents improved ergonomics of the ventral suspension point and the shoulder straps compared to the configurations of the prior art.

[0008] This result tends to be achieved by means of a harness, which comprises:

[0009] - a waistband, a first leg loop and a second leg loop, and a shoulder strap, the waistband having an inner face and an outer face;

[0010] - a first loop, which is attached to the waistband and is designed for the attachment of the shoulder strap;

[0011] - a second loop, which is attached to the waistband and is different from the first loop, the second loop being designed to form a ventral attachment point.

[0012] The harness is notable in that at least a first webbing strap defines a loop, which is firmly attached to the waistband and the leg loops, the first strap being fixed to the waistband by means of a seam;

[0013] - the first loop and the second loop are arranged within the loop, the first loop being outside the second loop and the second loop being outside the first loop; and

[0014] - the first loop is arranged to face the second loop in a direction parallel to a first direction passing through the inner face and the outer face of the waistband.

[0015] Advantageously, the first loop is mounted to be movable relative to the second loop in a direction parallel to the first direction.

[0016] In a particular configuration, the first loop is mounted to be movable relative to the second loop in a second direction perpendicular to the first direction and perpendicular to the longitudinal direction of the waistband.

[0017] In an advantageous refinement, the harness comprises a second strap separating the first loop and the second loop. The second strap has a first end fixed to the first strap.

[0018] Preferably, the second strap has a second end fixed to the waistband.

[0019] Preferably, the second strap at least partially covers a part of the first strap forming the first loop, the first loop being designed to receive the attachment portion of the shoulder strap.

[0020] According to one embodiment, the second strap is fixed to the waistband within the loop.

[0021] In a preferred manner, the first loop is designed to be arranged between the second loop and the ventral part of the user.

[0022] Advantageously, the harness comprises a leg loop link joining the first leg loop and the second leg loop. The leg loop link is arranged within the loop.

[0023] In a preferred refinement, the leg loop link is fixed to the waistband and the first strap.

[0024] In an advantageous refinement, the first strap is fixed to the second strap along a first loop by means of a first loop seam, and the first end of the first strap is fixed to the second end of the first strap by means of resistance seams. The resistance seams withstand a first stress applied between the second loop and the waistband, and the first loop seam yields to the first stress.

[0025] Advantageously, the first strap is fixed to the second strap along the waistband by means of a waistband seam, and the first end of the first strap is fixed to the second end of the first strap by means of resistance seams. The resistance seams withstand a first stress applied between the second loop and the waistband, and the waistband seam yields to the first stress.

[0026] Preferably, the second strap defines an additional loop arranged in the first loop, and the two ends of the second strap are fixed to the waistband.

[0027] In a preferred refinement, a removable connector of a link formed between the shoulder strap and the waistband is mounted in the first loop. Description of the Drawings

[0039] Figure 1 and Figure 2 Shows a harness including a waist belt 1 and a pair of leg loops 2, the leg loops 2 having a first leg loop 2' and a second leg loop 2". The harness also has a shoulder strap 3, one end of the shoulder strap 3 being preferably removably assembled relative to the waist belt 1.

[0040] The harness also includes a ventral suspension point 4 provided with a first loop 5 and a second loop 6. The first loop 5 is preferably designed to receive the attachment portion of the shoulder strap 3, such as a shoulder strap connector 7. The second loop 6 is preferably designed to be connected to an anchor point, such as a lifeline. The second loop 6 is designed to receive a line element, a suspension connector 8, or any other component by which the harness is suspended.

[0041] The ventral suspension point 4 is also referred to as the navel suspension point. The ventral suspension point 4 is capable of supporting a user mounted in the harness and suspended by the harness. The ventral suspension point 4 is arranged in the midsagittal plane and is located near the user's navel.

[0042] The waist belt 1 has a waistband that extends in the longitudinal direction defining the circumference of the waist belt 1. The length of the waistband is greater than its width, and its width itself is greater than its thickness. The waist belt 1 has an inner surface and an opposite outer surface, the inner surface being designed to face the user and preferably to contact the user.

[0043] The ventral suspension point 4 has a first strap 9 fixed to the waist belt 1, for example by a seam, to fix the ventral suspension point 4 to the waist belt 1. The first strap 9 forms a loop 10 around the waist belt 1. In other words, the waist belt 1 passes through the loop 10.

[0044] The ventral suspension point 4 has a first loop 5 and a second loop 6 that are different from each other. The first loop 5 and the second loop 6 are mounted within the loop 10. Since the first loop 5 is different from the second loop 6, an item (such as a rope or a connector) assembled in the first loop 5 cannot move to reach the second loop 6, and vice versa.

[0045] 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 is different from the structure disclosed in document EP2401038, which presents an outer loop arranged around an inner loop, where two connectors are arranged one above the other along the user's mouth-tail axis. The connector placed in the inner loop can only move within the space defined by the outer loop, and the forward movement of the inner loop will move another connector assembled in the other loop, which may be disadvantageous.

[0046] The first ring 5 and the second ring 6 are arranged in the loop 10. The first ring 5 and the second ring 6 are different from the loop 10. Forming the loop 10 through which the belt 1 passes enables the ventral suspension point 4 to be provided, which remains firmly fixed to the belt 1 in the event of a severe fall. This configuration enables the constraints on other attachments to be relaxed, especially on other seams where applicable.

[0047] In a particularly advantageous manner, the two leg loops 2 are joined to each other by a leg loop link 11 passing through the loop 10. In an alternative embodiment, each leg loop 2 is fixed to the belt 1, for example, by a specific seam, independently of the loop 10.

[0048] In the configuration of document EP2401038, the strap from the leg loop forms the ventral suspension point. The strap is fixed to the belt. The strap is wide and the dimensions of the seam are defined to withstand all fall stresses. The dimensions of the strap imply a certain stiffness. By using the loop 10 formed by a strap different from the leg loop 2, the width of the strap can be reduced and the fixed seam between the leg loop 2 and the belt 1 can be reduced, thereby improving the comfort of the connection between the leg loop 2 and the belt 1.

[0049] The first ring 5 and the second ring 6 are arranged side by side with respect to each other in a direction parallel to the axis passing through the outer and inner surfaces of the belt 1. In other words, the first ring 5 is designed to be located between the second ring 6 and the user. In a preferred manner, the first ring 5 receives the shoulder strap connector 7, which effects the mechanical connection between the shoulder strap 3 and the belt 1. The shoulder strap connector 7 can be a removable connector. The second ring 6 can receive the suspension connector 8, which is preferably a non-removable connector.

[0050] The first ring 5 and the second ring 6 are mounted to be movable relative to each other at the location of the attachment between the belt 1 and the loop 10 in a direction parallel to a first direction passing through the inner and outer surfaces.

[0051] The first ring 5 and the second ring 6 project from the belt 1 in a direction extending along the direction of the shoulder strap 3 (i.e., upward when the user is standing). Subsequently, movement can occur between the two rings, and thus between the two elements mounted in the two rings, thereby improving stress transfer on the belt 1. The movement of one ring relative to the other occurs in a direction passing through the outer and inner surfaces of the belt 1.

[0052] In a preferred manner, both the first ring 5 and the second ring 6 are mounted to be rotatable relative to the belt 1. The axis of rotation of each of the two rings extends in the longitudinal direction of the belt 1.

[0053] In a particularly advantageous manner, the loop 10 is attached to the belt 1 so as to freeze the position of the ventral suspension point 4 in the longitudinal direction of the belt 1 and to prevent the loop 10 from rotating around the belt 1 in the longitudinal direction and from rotating perpendicular to the longitudinal direction. Attaching the loop 10 to the belt 1 enables a better function of the two rings 5 and 6 to be achieved.

[0054] In Figure 3 In the particular embodiment shown, the two rings 5 and 6 are formed by a single first band 9, the two ends of the first band 9 being attached to each other to form the loop 10, and the first band 9 being shaped to define the two rings 5 and 6.

[0055] In Figures 4 to 8 and Figure 10 In the advantageous manner shown, the first band 9 and the second band 12 are used to form the first ring 5 and the second ring 6. The first band 9 forms the loop 10 around the belt 1. The second band 12 is arranged in the loop 10 to divide the loop 10 into the first ring 5 and the second ring 6.

[0056] The first band 9 is different from the band forming the first leg loop 2' and from the band forming the second leg loop 2". The same applies to the second band 12. The second band 12 is preferably fixed to the first band 9 by a seam to define the two rings.

[0057] The second band 12 separates the first ring 5 and the second ring 6. It is advantageous to fix the first band 9 and the second band 12 to the belt 1. The second band 12 is mounted within the loop 10 so as to separate the two spaces forming the two rings 5 and 6.

[0058] The first ring 5 is not located within the second ring 6 and vice versa. Preferably, each ring has a first end fixed to the belt 1, thus contributing to strain absorption on the belt 1. More preferably, each ring has a second end fixed to the belt 1. Each ring is different from the other ring such that an item placed in the first ring 5 cannot move to the second ring 6 and vice versa.

[0059] The first ring 5 and the second ring 6 are arranged to project from the belt 1 in the direction of the shoulder strap 3.

[0060] In a preferred manner, the loop 10 is closed by a seam joining two opposite ends of the first band 9, which seam is different from the seam performing the attachment to the belt 1, such that the seam closing the loop 10 and the seam attaching the loop 10 to the belt 1 work differently.

[0061] In a preferred manner, the two ends of the first band 9 fixed to each other to close the loop 10 form all or part of the first ring 5 or the second ring 6, and more preferably form at least part of the second ring 6. The doubling of the thickness increases the stiffness of the ring, making the latter easier to handle.

[0062] Advantageously, the overlap length between the two ends of the first strap 9 represents at least 30% of the length of the second loop 6, preferably the distance separating the two attachment points to the belt 1. More preferably, 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.

[0063] Particularly advantageously, the second strap 12 forms the curved part of the second loop 6 (i.e. the part designed to receive the shoulder strap connector 7). The second strap 12 prevents wear of the first strap 9. Preferably, the second strap 12 has a single end directly fixed to the belt 1. Direct attachment to the belt means an attachment in which a part of the second strap 12 is mounted in a fixed manner relative to a part of the belt 1. The second strap 12 can be in direct contact with the belt 1 or separated therefrom, for example, by the leg loop link 11. The fixation is preferably obtained by a stitching seam, in which the stitching thread passes through the second strap 12 and the belt 1 and can pass through the leg loop link 11 and preferably through the first strap 9. By fixing only one end of the second strap 12 to the belt 1, it is possible to ensure that when the connector tries to move away from the belt 1, stress is applied to the first strap 9 and the belt 1. This also promotes the formation of the second loop 6. If applicable, the stitching operation also becomes easier.

[0064] In a preferred manner, the overlap area between the two ends of the first strap 9 has an attachment, such as a stop seam 14, which extends in a continuous or almost continuous manner over the entire overlap length to prevent the installation of a connector or a wire element between the two strands of the first strap 9, thus preventing the formation of an additional loop.

[0065] It is also advantageous that the attachment between the belt 1 and the first strap 9 and the attachment between the belt 1 and the second strap 12 extend in a continuous or almost continuous manner to prevent the installation of a connector or a wire element between the belt 1 and each of the first strap 9 and the second strap 12, thus preventing the formation of an additional loop.

[0066] It is also advantageous that the attachment between the second strap 12 and the first strap 9 (for example, by the first loop seam 13) extends in a continuous or almost continuous manner to prevent the installation of a connector or a wire element between the first strap 9 and the second strap 12, thus preventing the formation of an additional loop.

[0067] These configurations prevent the attachment from working in an adverse mode, especially peeling when the attachment is a seam and especially when the ventral suspension point 4 is subjected to large stresses.

[0068] In the case where the attachment between the first strap 9 and the second strap 12 yields, one or more connectors and / or wire elements installed in the first loop 5 and / or the second loop 6 remain firmly fixed to the loop 10 and thus remain firmly fixed to the belt 1. This also applies in the case where the attachment between the belt 1 and the first strap 9 breaks.

[0069] This structure is advantageous because the different components are fixed to the belt 1 by means of the loop 10. Thus, the size of the ventral suspension point 4 can be reduced by choosing the loop 10, which exhibits mechanical properties selected to withstand a predefined set of stresses. This makes it possible, for example, to choose the thickness, width, material and configuration of the attachment of the loop 10 closed on the first strap 9.

[0070] The attachment between the belt 1 and the first strap 9, the attachment between the belt 1 and the second strap 12, and the attachment between the first strap 9 and the second strap 12 can be chosen to have lower properties. The second strap 12 can also be chosen to have lower properties than the first strap 9.

[0071] 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 (such as a lifeline). The first loop 5 is at least partially covered by the second strap 12. More preferably, the attachment between the first strap 9 and the second strap 12 is obtained by a stitched seam.

[0072] When a stress is applied between the first loop 5 and the second loop 6, the first loop seam 13 between the first strap 9 and the second strap 12 along the first loop 5 acts in peel. Advantageously, these first loop seams 13 are configured to yield when subjected to a first threshold stress, which is equal to the maximum allowable stress above which the suspension point can no longer be used, and which is lower than the stress that causes the loop 10 to break. In other words, the first strap 9 is fixed to the second strap 12 along the first loop 5 by the first loop seam 13, and the first end of the first strap 9 is fixed to the second end of the first strap 9 by a stop seam 14. The stop seam 14 resists the first stress applied between the second loop 6 and the belt 1, and the first loop seam 13 yields to the first stress.

[0073] Thus, when the user observes the breakage of the seam line forming the link between the first strap 9 and the second strap 12 along the first loop 5, the user detects that the harness is no longer usable. The seam line serves as an indication that a stress greater than the maximum allowable stress has been applied.

[0074] The same applies to the seam line forming the attachment between the loop 10 and the belt 1. For example, the first strap 9 is fixed to the belt 1 by a belt seam 15, and the first end of the first strap 9 is fixed to the second end of the first strap 9 by a stop seam 14. The stop seam 14 resists the first stress applied between the second loop 6 and the belt 1, and the belt seam 15 yields to the first stress. The same applies when the belt seam 15 fixes the belt 1 and the first strap 9 to each other, or the belt 1 and the second strap 12 to each other, or the belt 1, the first strap 9 and the second strap 12 to each other.

[0075] In Figure 4In the embodiment, the second strap 12 is arranged to abut against the outer side of the waistband 1, but very similar operation can be obtained by placing the second strap 12 to abut against the inner side of the waistband 1, as Figure 5 shown. Placing the second strap 12 on one side or the other side of the waistband 1 only slightly changes the mechanical properties of the ventral suspension point 4. On the other hand, attaching the second strap 12 to the waistband 1 ensures better strain absorption of the waistband 1 compared to the second strap 12 attached to the second loop 6 to close the second loop 6.

[0076] In an alternative embodiment, the second strap 12 has a breaking elongation rate lower than that of the attachment portion. If a large stress is applied, the second strap 12 breaks in the separation area between the first loop 5 and the second loop 6. The breakage of the second strap 12 is observed as an indication that the stress is higher than the threshold.

[0077] It is advantageous to form the second loop 6 by means of the two ends of the first strap 9, because in the case of applying a severe stress, such as in the case of a fall, the attachment portion between the two ends works in a more favorable mode, so that better breaking strength can be achieved.

[0078] In Figure 6 and Figure 7 the shown embodiment, the second strap 12 is arranged in the second loop 6. The first loop 5 can be closed by the first loop seam 13 to serve as an indication of yielding when the suspension point is subjected to a large stress. The second strap 12 can also be broken. However, this embodiment is not as advantageous as Figure 4 and Figure 5 the embodiment, because it is more difficult to monitor the breaking stress of the indication. Similarly, the second strap 12 can be located on one side or the other side of the waistband 1.

[0079] Figure 7 and Figure 8 show an embodiment in which the second strap 12 is used and the second strap does not perform separation between the two loops. This embodiment is not as advantageous as the previous embodiments, because the closing of the loop is performed by at least one seam, preferably by the seams at the ends of each loop. This embodiment is less advantageous because: due to the higher stress applied to the seams, the separation between the loops is not easily grasped in time.

[0080] The first strap 9 forms a loop 10 around the waistband 1. Preferably, the leg loop link 11 passes through the loop 10. More preferably, the leg loop link 11 is fixed to the waistband 1 by the same seam as the first strap 9 and possibly the same seam as the second strap 12.

[0081] Preferably, the first loop 5 and the second loop 6 are arranged to face each other in a direction perpendicular to the outer side of the waistband 1. The two loops pass through in the longitudinal direction of the waistband 1.

[0082] It is particularly advantageous to use a leg loop link 11 that connects the two leg loops 2 and passes through the loop 10, as it provides a mechanical connection between the leg loops 2 and the belt 1 while relaxing the process constraints of the attachment between the leg loops 2 and the belt 1.

[0083] 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 Figure 9 shown.

[0084] In Figure 10 the embodiment shown, the ventral suspension point 4 defines three loops and an additional loop, where the additional loop is located in the first loop 5. The additional loop is formed by the second strap 12, and preferably the part of the second strap 12 that separates the first loop 5 and the second loop 6 is used. In a preferred manner, the shoulder strap connector 7 is mounted in the first loop 5 outside the additional loop. More preferably, the shoulder strap connector 7 can be removed from the first loop 5. The shoulder strap connector 7 forms a connecting link between the shoulder strap 3 and the belt 1.

[0085] Advantageously, one or more removable connectors are mounted in the additional loop. The second loop 6 is used to attach the harness to an anchor point.

[0086] In professional harnesses designed for working at height, there is typically a ventral suspension point positioned facing the user's navel. This configuration makes it easier to mount items of different equipment that will be used during long suspension phases. This explains why the configuration of a harness designed for working at height is different from that of a climbing harness, which is more commonly referred to as a "sports harness".

[0087] In the configuration of prior art harnesses for working at height, the woven strap forming the leg loop link is fixed to the belt and forms one or more loops that mark the ventral suspension point. Therefore, the performance of the leg loop strap is selected to withstand the stress of the ventral suspension point.

[0088] Broad straps are typically used to form the loops of the ventral suspension point, and the strap extends to the two leg loops. To provide strength in the event of a fall, seams need to be stitched over a large surface between each webbing strand and the belt. The prior art configuration means that the leg loop link has a large inclination from the ventral suspension point 4 until the leg loop 2. This configuration limits the comfort of the user at the thigh level, especially when the user is suspended by the harness.

[0089] To improve the user's comfort around the ventral suspension point 4 without making the rope harness too complex to manufacture, it is advantageous to use a joining strap that joins the first leg loop to the second leg loop. The joining strap passes through the loop 10 such that the joining strap is always firmly attached to the belt 1 via the loop 10.

[0090] The joining band defines folding portions 16, where a first folding portion 16' is between the central portion of the joining band and a first strand extending from the first leg loop 2'. A second folding portion 16'' is defined by the joining band between the central portion of the joining band and a second strand extending from the second leg loop. The first folding portion is separated from the second folding portion by the loop 10. The two strands are attached to the waistband 1 at a greater separation distance than in the prior art configuration.

[0091] In a preferred manner, the first folding portion and the second folding portion are firmly attached to the waistband 1 by at least one seam. Advantageously, the central portion of the joining band is firmly attached to the waistband 1 such that the waistband 1 and the central portion deform in the same manner in the longitudinal direction of the waistband 1 and in the transverse direction of the waistband 1.

[0092] The first folding portion 16' and the second folding portion 16'' are separated by the loop in the longitudinal direction of the waistband 1.

[0093] In a preferred manner, the first folding portion 16' and / or the second folding portion 16'' are attached to the waistband 1 by a folding seam 17. The loop 10 is formed by a first band 9, and the first end of the first band 9 is attached to the second end by a stop seam 14. The stop seam 14 withstands a first stress applied between the first ring 5 and the leg loop 2, and the folding seam 17 yields to the first stress.

[0094] Advantageously, the leg loop link 11 is attached to the waistband 1 by a waistband seam 15. The loop 10 is formed by a first band 9, and the first end of the first band 9 is attached to the second end by a stop seam 14. The stop seam 14 withstands a first stress applied between the first ring 5 and the leg loop 2, and the waistband seam 15 yields to the first stress.

[0095] Using a waistband seam 15 and / or a folding seam 17 that is less strong than the stop seam 14 provides an indication of excessive stress on the harness. The first stress can be expressed as the maximum allowable stress of the harness. When the harness is subjected to a stress higher than a threshold, the folding seam 17 and / or the waistband seam 15 yield. The yielding seam acts as an indicator.

[0096] Mounting the leg loop link 11 inside the loop 10 and separating the leg loop link 11 and the ring designed to be attached to the anchor point enables modification of the mechanical behavior of the band forming the link between the leg loop 2 and the ventral suspension point 4. The wider the first band 9 forming the ring, the greater the strength of the ventral suspension point 4, all other parameters being equal. However, this makes the ring less practical and limits the user comfort of the leg loop link when the band extends upwards to the leg loop 2.

[0097] To form the leg loop link 11, it is advantageous to use a belt that is less wide than the belts of the prior art, thus improving the comfort of the leg loop link. In particular, it is advantageous to use a belt with a smaller width and / or a smaller thickness than the belt forming the waist belt 1. If other parameters, especially cost, are not adversely affected, a more flexible belt can also be used, which generally corresponds to a belt with a lower breaking elongation.

[0098] In a preferred manner, between the first fold 16' and the second fold 16'', the leg loop link 11 extends mainly or only in the longitudinal direction of the waist belt 1, and the leg loop link 11 is firmly attached to the waist belt 1. The leg loop link 11 and the waist belt 1 are deformed in a similar manner, resulting in a more uniform mechanical function between the leg loop link 11 and the waist belt 1.
