A roping harness having a sit harness, pair of shoulder straps, and at least one securing link having a first strap unfurlable in the lengthwise direction, and composed of two superposed strands secured to one another by a stitching area, designed to tear when a fall happens separating the strands and moving the connecting loop from a lowered to a raised position. The securing link includes a second strap connecting the sternal attachment to the corresponding sit harness strap. The first strap bottom strand is attached to the belt and is shorter length than the unfurlable top strand. The top strand is fixed to the sternal attachment, such that tearing of the stitching area releases the bottom strand. The top strand moves to the raised position attached to the sternal attachment to transfer the reaction of the shock of a fall onto the second strap connected with the leg loops. |

1. A roping harness comprising:
a sit harness composed of a support belt and a pair of leg loops, a pair of shoulder straps each comprising a chest strap extended by a back belt, at least one connecting loop designed to be connected to a fall arrest apparatus, at least one securing link having a first strap unfurlable in the lengthwise direction and composed of two superposed strands secured to one another by a safety stitching area which is designed to tear in the event of a fall to separate the two strands and to move the connecting loop from a lowered position to a raised position, wherein the securing link comprises a second strap connecting the sternal attachment to the strap of the corresponding sit harness,
the bottom strand of the first strap being attached to the belt and having a shorter length than that of the unfurlable top strand,said top strand being fixed to the sternal attachment, such that tearing of the stitching area releases the bottom strand, whereas the top strand moves to the raised position remaining attached to the sternal attachment so as to transfer the reaction of the shock undergone when a fall occurs onto the second strap which is connected with the leg loops. |
