Abstract

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.

First claim

The invention claimed is:

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.

2. The roping harness according to claim 1 , wherein:
the at least one connecting loop is two connecting loops, and the at least one securing link is two securing links, and
the maximum elongation of the two securing links is capable of placing the two connecting loops above the center of gravity of the user and beyond the level of the two sternal attachments.

3. The roping harness according to claim 2 , wherein the two connecting loops form a double connection point for a connector.

4. The roping harness according to claim 1 , wherein the sternal attachment acts as a common attachment for the chest strap of the shoulder straps, the second strap, and the top strand of the first strap.

5. The roping harness according to claim 1 , wherein an auxiliary fusible stitching is provided on the first strap between the safety stitching area and the support belt.

6. The roping harness according to claim 1 , wherein the first end of the bottom strand is stitched to the support belt.

7. The roping harness according to claim 1 , wherein the front end of the chest strap extends through the sternal attachment and is stitched over itself.

8. The roping harness according to claim 1 , wherein the second strap and a top end of the top strand are connected to the sternal attachment by a resistant stitching.

9. The roping harness according to claim 1 , wherein the second strap connects the sternal attachment to one of the leg loops of the sit harness.
