    [0001] TECHNICAL FIELD OF THE INVENTION The invention relates to a roping harness comprising: - a pair of shorts consisting of a support belt and a pair of thigh turns, - a pair of straps each having a thoracic strap extended by a back strap, - at least one connecting loop for connection to a fall arrest apparatus, - and at least one retaining link having a first strap deployable in length, and consisting of two strands The bunches are held together by a safety seaming zone, which is capable of tearing during a fall to separate the two strands and move the connecting loop from a lowered position to a raised position. STATE OF THE ART For certain work at height, known harnesses have at the front 30 two ventral and / or sternal hooking loops intended to be connected to a fall arrest device for the safety of the users. The mechanical fall arrest device is arranged to slide along a rail or a lifeline, for example fixed to a fixed vertical ladder, following the progression of the user in the direction of the ascent or descent. In the event of a fall, the fall arrest device automatically locks to secure the user. Operation is facilitated when the fall arrest device is connected to the ventral loops located in the lower position in the vicinity of the belt. By cons in case of a fall, the user may turn around and fall head down. A recent European standard requires any fall protection connection point to be above the user's center of gravity after the fall. The connection of the fall arrest device to the sternal loops would be a solution that would meet the standard in the event of a fall. Nevertheless, during the normal progression of the user, the latter would have the fall arrest device permanently in front of and near his eyes, thereby causing some discomfort and visual discomfort. The documents WO2011 / 121242 and EP2552551 (Tractel) describe a harness comprising a metal hooking ring which during a fall, passes from a low point to a high point after tearing of a seam system. But the ring is disposed on a horizontal retaining strap extending between the front portions of the two straps. The whole remains attached to the belt that must withstand the shock in case of a fall.
    [0002] The passage from a downstream point to an upstream point of the connection loop of a harness is also known per se from EP 1803487. Object of the invention The object of the invention consists in producing a harness Advanced roping for work at height, having a secure and comfortable roping system in both normal progression situations and after the fall.
    [0003] The harness according to the invention is characterized in that the retaining link comprises a second strap connecting the sternal attachment to the strap of the corresponding thigh turn, and that the lower strand of the first strap is attached to the belt. and has a shorter length than the deployable upper strand, which is attached to the sternal attachment, such that tearing of the seam area releases the lower strand, while the upper strand moves to the raised position while remaining attached to the sternal tie so as to postpone the reaction of the shock received during the fall on the second strap in connection with the leg loops. This results in a separation of the connection loops with the belt, and a recovery of efforts by the sternal fasteners in connection with the shoulder straps and the second strap in extension of the leg loops. According to a preferred embodiment, the connection loop is carried by the lower end of the upper strand of the first strap and is in the lowered position above the closure loop of the belt. The connection of the lower strand is interrupted with the corresponding sternal tie when tearing the stitch area. Preferably, the sternal tie serves as a means of common attachment of the chest strap of the shoulder strap, the second strap, and the deployable upper strand of the first strap. BRIEF DESCRIPTION OF THE DRAWINGS Other advantages and features will emerge more clearly from the following description of an embodiment of the invention given by way of non-limiting example, and represented in the appended drawings in which: FIG. 1 is a schematic view of the harness according to the invention, with the two connection loops in the lowered position and corresponding to the normal state of progression of the user; FIG. 2 represents a view similar to FIGS. 1 and 2, during the triggering of the sewing zone of the link, following a fall of the user; FIG. 3 shows the end of the tearing phase of the seam zone of the connection, with the two connection loops in the raised position, above the user's center of gravity, and above the Sternal attachment loops, FIGS. 4 and 5 illustrate detailed views of the two constituent straps of the retaining links of FIGS. 1 and 3.
    [0004] Detailed Description of the Invention In Figures 1 to 3, a roping harness 10 is composed of a shorts 11 associated with a pair of straps 12, 13 crossed in the back of the user. The shorts 11 comprise a belt 14 for holding around the size of the user, and a pair of leg loops 15, 16 connected to the belt 14 on either side of the central closure loop 17. Each shoulder strap 12, 13 comprises at the front a thoracic strap 12a, 13a extended at the rear by a back strap 12b, 13b so as to pass over the shoulder of the user. Depending on the size of the user, the thoracic strap 12a, 13a is adjustable in length by means of a first adjustment loop 18, 19. The anterior ends of the two chest straps 12a, 12b of the straps 12, 13 are fixed at the front with two sternal fasteners 20, 21 in the form of rings. The posterior ends of the back straps 12b, 13b of the shoulder straps 12, 13 are attached to the waistband 14. Each leg circumference 15, 16 has a second adjustment loop 22, 23 to adjust the perimeter according to the morphology of the user.
    [0005] A pair of retaining links 24, 25 are further arranged at the front of the harness to connect the shoulder straps 12, 13 to the shorts 11. Each retaining link 24, 25 has a first strap 24a, 25a deployable in length. carrying a connecting loop 26, 27 at the end, and a second strap 24b, 25b connecting the sternal tie 20, 21 corresponding to an extension of the thigh strap 15, 16. The two connecting loops 26 27 form a double point of connection for a connector (not shown), which is intended to be connected by a flexible lanyard to a mechanical fall arrest device (not shown). This fall arrest safety device is independent of the harness 10, for example, being slidably mounted along a rail or a fixed lifeline. Such a fall arrest device follows the user during his progression uphill or down the rail. In the event of a fall of the user, the fall arrest device 20 automatically switches from the unlocked state to the locked state, so as to stop the fall and to secure the user. The latter is then hooked to the rail or the lifeline by the lanyard. The first deployable straps 24a, 24b in length are able to vary the positioning of the double point of connection of the connection loops 26, 27 during a fall. The double connection point of the connection loops 26, 27 then moves from the lowered position located near the level of the belt 11 (FIG. 1) to the raised position (FIG. 3) located above the level of the sternal fasteners. 21. The second 30 straps 24b, 25b permanently connect the straps of thighs 15, 16 to the corresponding sternal fasteners 20, 21 during this passage. According to the embodiment illustrated in FIGS. 1 to 3, the first deployable strap 24a, 25a of each retaining link 24, 25 comprises two strands A, B plated and held against one another by a seaming zone. ZC, which is configured to resist up to said predetermined voltage threshold. It is clear that the seams can be made by equivalent means, including self-gripping closure strips. The lower strand A of the first strap 24a, 25a is attached to the belt 14, while the upper strand B is not. The latter carries the connection loop 26, 27 at its lower end, and is fixed permanently by its end opposite the sternal attachment 20, 21. The lower strand A is not attached to the sternal attachment 20, 21, and its length is chosen to be smaller than that of the superimposed strand B. In case of tearing of the seam zone ZC (FIG. 3), the connection of the lower strand A is interrupted with the corresponding sternal fastener 20, 21. The operation of the harness 10 according to the invention is as follows: In FIG. 1, the seam zone ZC holds the two strands A, B of the first strap 24a, 25a against each other, so as to positioning the double connection point of the connection loops 26, 27 in the lowered position, just above the closure loop 17 of the belt 14. This position is advantageously located in the vicinity of the user's center of gravity, and corresponds in the normal progression phase along the rail or lifeline. The slip of the fall arrest device does not cause tearing of the ZC seam area. In case of a fall of the user, the tension exerted on the upper strand B causes the progressive tearing of the sewing zone ZC (FIG. 2). The strand B with its connecting loop 26, 27 is detached from the lower strand A in the direction of the sternal fastener 20, 21. In the position of Figure 3, tearing of the entire ZC stitching zone has caused the separation along the entire length of the two strands A, 35 B of the first deployable strap 24a, 25a. The lower strand of each deployable strap 24a, 25a is floating, but remains attached to the belt 14. The fully detached upper strand B is attached to the sternal strut 20, 21. The elongation maximum of the two retaining links 24, 25 places the double connection loop 26, 27 above the center of gravity and beyond the level of the two sternal attachments 20, 21. The reaction of the shock received during the fall is postponed completely on the second strap 24b, 25b in connection with the leg loops 15, 16. Such a raised position of the double loop connection 26, 27 provides comfortably secure the user in case of a fall. FIGS. 4 and 5 show detailed views of the two straps 25a, 25b constituting the right-hand retaining link of FIGS. 1 and 3, respectively before and after tearing of the ZC seam zone, that is to say when the connection loop 27 is in the lowered position and in the raised position deployed.
    [0006] It will be noted that the sternal fastener 21 serves as a means of common attachment of the thoracic strap 13a of the strap 13, the second strap 25b, and the expandable strand B of the first strap 25a. A fuse seam 28 is advantageously provided on the first strap 25a between the plating seam zone ZC and the belt 14. Fig. 5 shows the fusible seam 28 disjointed on the strand A after firing. A resistant seam 29 connects the second strap 25b and the upper end of the strand B of the first strap 25a to the sternal fastener 21. This results in a separation of the connection loop 27 with the belt 14, and a recovery efforts by the sternal tie 21 in connection with the shoulder strap 13a and the second strap 25b in extension of the leg circumference 16.
