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 the 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 with two woven loops that are arranged to nest within each other and are closed by the 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 and outer loops are formed by a woven strap that extends 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 for the ventral suspension point and the shoulder straps compared to the configurations of the prior art.

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

[0009] - a waistband, a first leg loop, a second leg loop and a joining strap, the joining strap forming a leg loop link connecting the first leg loop and the second leg loop;

[0010] - a loop, which is firmly attached to the waistband and is passed through by the leg loop link;

[0011] - a first ring, which is fixed to the waistband to form a ventral suspension point.

[0012] The joining strap forms a first fold between a first strand extending from the first leg loop and a central portion, and forms a second fold between a second strand extending from the second leg loop and the central portion.

[0013] The central portion extends mainly in the longitudinal direction of the waistband from the first fold to the second fold, and the central portion is fixed to the waistband between the first fold and the second fold.

[0014] The loop contains a first ring, which is arranged to project from the waistband in a direction opposite to the first leg loop and the second leg loop.

[0015] The first fold and the second fold are arranged on each side of the loop in the longitudinal direction beyond the loop.

[0016] At least one seam fixedly fastens the loop, the central portion of the joining strap and the waistband, and the loop surrounds the central portion of the joining strap and the waistband.

[0017] Advantageously, the first fold and the second fold are fixed to the waistband by at least one seam.

[0018] In a specific configuration, the leg loop link is fixed to the waistband by a waistband seam, wherein the loop is formed by a first strap having a first end fixed to a second end by resistance seams. The resistance seams withstand a first stress applied between the first ring and the leg loops, and the waistband seam yields to the first stress.

[0019] In an advantageous improvement, the first fold and / or the second fold are fixed to the waistband by a folding seam, wherein the loop is formed by a first strap having a first end fixed to a second end by resistance seams, and wherein the resistance seams withstand a first stress applied between the first ring, the first leg loop and the second leg loop, and wherein the folding seam yields to the first stress.

[0020] In an advantageous improvement, the first strap is fixed to a second strap along the first ring by a first ring seam, and the first end of the first strap is fixed to the second end of the first strap by resistance seams. The resistance seams withstand a first stress applied between the second ring and the waistband, and the first ring seam yields to the first stress.

[0021] Advantageously, the leg loop link is made of a joining band that exhibits a breaking strength in the direction of connecting the first leg loop to the second leg loop that is lower than the breaking strength in the direction of the loop in a direction perpendicular to the longitudinal direction of the waistband.

[0033] Figure 1 and Figure 2 A harness including a waistband 1 and a pair of leg loops 2 is shown, the leg loops 2 having a first leg loop 2' and a second leg loop 2". The harness further has shoulder straps 3, one end of the shoulder straps 3 being preferably removably assembled relative to the waistband 1.

[0034] The harness further 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 an 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.

[0035] 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 median sagittal plane and is located near the user's navel.

[0036] The waist belt 1 has a waist belt strap that extends in the longitudinal direction defining the circumference of the waist belt 1. The length of the waist belt strap is greater than its width, and its width itself is greater than its thickness. The waist belt 1 has an inner face and an opposite outer face, and the inner face is designed to face the user and preferably contact the user.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] The first loop 5 and the second loop 6 are arranged in the loop 10. The first loop 5 and the second loop 6 are different from the loop 10. Forming the loop 10 through which the waist belt 1 passes enables the ventral suspension point 4 to remain firmly fixed to the waist belt 1 in the event of a severe fall. This configuration enables the relaxation of the constraints on other attachment portions, particularly on other seams where applicable.

[0041] 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 waist belt 1, for example by a specific seam, independently of the loop 10.

[0042] In the configuration of document EP2401038, the strap from the leg loop forms a ventral suspension point. The strap is fixed to the waist 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 waist belt 1 can be reduced, thereby improving the comfort of the connection between the leg loop 2 and the waist belt 1.

[0043] The first loop 5 and the second loop 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 waist belt 1. In other words, the first loop 5 is designed to be located between the second loop 6 and the user. In a preferred manner, the first loop 5 receives the shoulder strap connector 7, which performs the mechanical connection between the shoulder strap 3 and the waist belt 1. The shoulder strap connector 7 can be a removable connector. The second loop 6 can receive the suspension connector 8, which is preferably a non-removable connector.

[0044] The first loop 5 and the second loop 6 are mounted to be movable relative to each other in a direction parallel to a first direction passing through the inner and outer surfaces at the position of the attachment between the waist belt 1 and the loop 10.

[0045] The first loop 5 and the second loop 6 are assembled to protrude from the waist belt 1 in a direction extending along the shoulder strap 3 (i.e., upward when the user is standing). Subsequently, there can be movement between the two loops, and thus there can be movement between the two elements mounted in the two loops, thereby improving the stress transfer on the waist belt 1. The movement of one loop relative to the other occurs in a direction passing through the outer and inner surfaces of the waist belt 1.

[0046] In a preferred manner, both the first loop 5 and the second loop 6 are assembled to be rotatable relative to the waist belt 1. The axis of rotation of each of the two loops extends in the longitudinal direction of the waist belt 1.

[0047] In a particularly advantageous manner, the loop 10 is attached to the waist belt 1 so as to freeze the position of the ventral suspension point 4 in the longitudinal direction of the waist belt 1 and prevent the loop 10 from rotating around the waist belt 1 in the longitudinal direction and from rotating perpendicular to the longitudinal direction. Attaching the loop 10 to the waist belt 1 enables better functioning of the two loops 5 and 6.

[0048] In Figure 3 In the specific embodiment shown, the two loops 5 and 6 are formed by a single first strap 9, the two ends of the first strap 9 are attached to each other to form the loop 10, and the first strap 9 is shaped to define the two loops 5 and 6.

[0049] In Figures 4 to 8 And Figure 10In the advantageous manner shown, the first strap 9 and the second strap 12 are used to form the first loop 5 and the second loop 6. The first strap 9 forms a loop 10 around the waistband 1. The second strap 12 is arranged within the loop 10 to divide the loop 10 into the first loop 5 and the second loop 6.

[0050] The first strap 9 is different from the strap forming the first leg loop 2' and different from the strap forming the second leg loop 2". The same applies to the second strap 12. The second strap 12 is preferably fixed to the first strap 9 by a seam to define the two loops.

[0051] The second strap 12 separates the first loop 5 and the second loop 6. Advantageously, the first strap 9 and the second strap 12 are fixed to the waistband 1. The second strap 12 is mounted within the loop 10 so as to separate the two spaces forming the two loops 5 and 6.

[0052] The first loop 5 is not located within the second loop 6 and vice versa. Preferably, each loop has a first end fixed to the waistband 1, thereby contributing to strain absorption on the waistband 1. More preferably, each loop has a second end fixed to the waistband 1. Each loop is different from the other loop such that an item placed in the first loop 5 cannot move to the second loop 6 and vice versa.

[0053] The first loop 5 and the second loop 6 are arranged to project from the waistband 1 in the direction of the shoulder strap 3.

[0054] In a preferred manner, the loop 10 is closed by a seam joining two opposite ends of the first strap 9, which seam is different from the seam performing the attachment to the waistband 1, such that the seam closing the loop 10 and the seam attaching the loop 10 to the waistband 1 work differently.

[0055] In a preferred manner, the two ends of the first strap 9 fixed to each other to close the loop 10 form all or part of the first loop 5 or the second loop 6, and more preferably form at least part of the second loop 6. The doubling of the thickness increases the stiffness of the loop to make the latter easier to handle.

[0056] Advantageously, the overlapping 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 waistband 1. More preferably, the overlapping 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.

[0057] Advantageously, the second strap 12 forms the curved portion of the second loop 6 (i.e., the portion 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 waist belt 1. Direct attachment to the waist belt means an attachment in which a portion of the second strap 12 is mounted in a fixed manner relative to a portion of the waist belt 1. The second strap 12 may be in direct contact with the waist belt 1 or separated therefrom, for example, by the leg loop link 11. The fixation is preferably obtained by a stitching seam, where the stitching thread passes through the second strap 12 and the waist belt 1 and may 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 waist belt 1, it is ensured that when the connector attempts to move away from the waist belt 1, stress is applied to the first strap 9 and the waist belt 1. This also promotes the formation of the second loop 6. If applicable, the stitching operation also becomes easier.

[0058] In a preferred manner, the overlapping region between the two ends of the first strap 9 has an attachment, such as a stop seam 14, which extends continuously or almost continuously over the entire overlapping length to prevent the installation of a connector or a wire element between the two strands of the first strap 9, thereby preventing the formation of an additional loop.

[0059] It is also advantageous that the attachment between the waist belt 1 and the first strap 9 and the attachment between the waist belt 1 and the second strap 12 extend continuously or almost continuously to prevent the installation of a connector or a wire element between each of the waist belt 1 and the first strap 9 and the second strap 12, thereby preventing the formation of an additional loop.

[0060] It is also advantageous that the attachment between the second strap 12 and the first strap 9 (e.g., by the first loop seam 13) extends continuously or almost continuously to prevent the installation of a connector or a wire element between the first strap 9 and the second strap 12, thereby preventing the formation of an additional loop.

[0061] 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.

[0062] 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 waist belt 1. The same applies to the case where the attachment between the waist belt 1 and the first strap 9 breaks.

[0063] This structure is advantageous because the fixation of the different elements to the belt 1 is maintained by means of the loop 10. Thus, it is possible to reduce the size of the ventral suspension point 4 by choosing the loop 10, which presents mechanical properties chosen 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 to the first band 9.

[0064] The attachment between the belt 1 and the first band 9, the attachment between the belt 1 and the second band 12, and the attachment between the first band 9 and the second band 12 can be chosen to have lower properties. It is also possible to choose a second band 12 having lower properties than the first band 9.

[0065] 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 band 12. More preferably, the attachment between the first band 9 and the second band 12 is obtained by a stitched seam.

[0066] When a stress is applied between the first loop 5 and the second loop 6, the first loop seam 13 between the first band 9 and the second band 12 along the first loop 5 acts in peeling. 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 band 9 is fixed to the second band 12 along the first loop 5 by the first loop seam 13, and the first end of the first band 9 is fixed to the second end of the first band 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 said first stress.

[0067] Thus, when the user observes the breakage of the seam line forming the link between the first band 9 and the second band 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.

[0068] The same applies to the seam line forming the attachment between the loop 10 and the belt 1. For example, the first band 9 is fixed to the belt 1 by a belt seam 15, and the first end of the first band 9 is fixed to the second end of the first band 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 said first stress. The same is true when the belt seam 15 fixes the belt 1 and the first band 9 to each other, or the belt 1 and the second band 12 to each other, or the belt 1, the first band 9 and the second band 12 to each other.

[0069] 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 very 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 with attaching the second strap 12 to the second loop 6 to close the second loop 6.

[0070] 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.

[0071] 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.

[0072] 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 the embodiments of Figure 4 and Figure 5 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.

[0073] Figure 7 and Figure 8 show embodiments 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 closure of the loop is performed by at least one seam, preferably by seams at the ends of each loop. This embodiment is less advantageous because it is not easy to grasp the separation between the loops in a timely manner due to the high stress applied to the seams.

[0074] 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.

[0075] 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.

[0076] It is particularly advantageous to use a leg loop link 11 that connects 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 technological constraints of the attachment between the leg loops 2 and the belt 1.

[0077] The ventral suspension point 4 can have a first loop 5 and a second loop 6. However, as an alternative, the suspension point can have only the first loop 5 or only the second loop 6, as Figure 9 shown.

[0078] 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 a 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.

[0079] 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.

[0080] In professional harnesses designed for working at heights, there is usually 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 heights is different from that of a climbing harness, which is more commonly referred to as a "sports harness".

[0081] In the configuration of prior art harnesses for working at heights, 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.

[0082] 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 on 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 to the leg loops 2. This configuration limits the user's comfort at the thigh level, especially when the user is suspended by the harness.

[0083] 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 so that the joining strap is always firmly attached to the belt 1 through the loop 10.

[0084] The joining strap defines folding portions 16, where a first folding portion 16' is between the central portion of the joining strap and a first strand extending from the first leg loop 2'. A second folding portion 16'' is defined by the joining strap between the central portion of the joining strap and a second strand extending from the second leg loop. The first folding portion is separated from the second folding portion by a loop 10. The two strands are attached to the waistband 1 at a greater separation distance than in the prior art configuration.

[0085] 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 strap 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.

[0086] The first folding portion 16' and the second folding portion 16'' are separated by a loop in the longitudinal direction of the waistband 1.

[0087] 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 strap 9, and a first end of the first strap 9 is attached to a second end by a blocking seam 14. The blocking 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.

[0088] 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 strap 9, and a first end of the first strap 9 is attached to a second end by a blocking seam 14. The blocking 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.

[0089] Using a waistband seam 15 and / or a folding seam 17 that is less strong than the blocking 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 indication.

[0090] Mounting the leg loop link 11 inside the loop 10 and separating the leg loop link 11 from the ring designed to be attached to the anchor point enables modification of the mechanical behavior of the strap forming the link between the leg loop 2 and the ventral suspension point 4. The wider the first strap 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 strap extends upward to the leg loop 2.

[0091] In order to form the leg loop link 11, it is advantageous to use a strap that is less wide than the straps of the prior art, thereby improving the comfort of the leg loop link. In particular, it is advantageous to use a strap with a smaller width and / or a smaller thickness than the strap forming the waistband 1. If other parameters, in particular the cost, are not adversely affected, a more flexible strap can also be used, which generally corresponds to a strap with a lower elongation at break.

[0092] 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 waistband 1, and the leg loop link 11 is firmly attached to the waistband 1. The leg loop link 11 and the waistband 1 are deformed in a similar manner, resulting in a more uniform mechanical function between the leg loop link 11 and the waistband 1.
