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 of the shoulder straps comprising a chest strap extended by a back belt, said chest strap having a front end attached to a sternal attachment,
at least one connecting loop designed to be connected to a fall arrest apparatus, and
at least one securing link having (1) a first strap unfurlable in the lengthwise direction, the first strap comprising 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 at least one connecting loop from a lowered position to a raised position, and (2) a second strap connecting the sternal attachment to the sit harness, wherein:
the two superposed strands include a bottom strand and a top strand, the top strand being unfurlable,
the bottom strand has a first end attached to the support belt and a second end stitched to the top strand by the safety stitching area, the bottom strand having a length that is shorter than a length of the top strand,
the at least one connecting loop is supported by a bottom end of the top strand and is above a closing loop of the support belt when in the lowered position,
the top strand is fixed to the sternal attachment, such that tearing of the safety stitching area releases the bottom strand from its connection to the top strand, whereas the top strand moves to the raised position remaining attached to the sternal attachment so as to transfer a reaction of shock undergone when a fall occurs onto the second strap which is connected with the leg loops, and
a mechanical connection of the bottom strand with the corresponding sternal attachment, via the top strand, is interrupted when tearing of the stitching area takes place such that the first end of the bottom strand remains attached to the support belt, and the second end of the bottom strand is capable of moving freely relative to the top strand.
