Abstract

There is provided a full body harness comprising a chest strap, an abdomen strap and a damping unit between the chest strap and the abdomen strap. The damping unit is adapted in the event of a fall to limit the maximum loading acting on the wearer of the harness. The damping unit has a connection for connection to an external runner.

First claim

The invention claimed is:

1. A full body harness comprising:
a front chest strap that traverses a user's chest substantially horizontally from a right front side of the user to a left front side of the user when worn by the user;
a front abdomen strap that traverses the user's abdomen below the front chest strap substantially horizontally from a right front side of the user to a left front side of the user when worn by the user;
a runner adapted to run in a rail;
a ring or a fixing unit coupled to the runner; and
a damping unit having a first end, a middle portion, and a second end, the middle portion being between the first and second ends, the first end directly coupled to a center portion of the chest strap and the second end directly coupled to a center portion of the abdomen strap, the damping unit having a single longitudinal axis extending vertically between the center portion of the front chest strap and the center portion of the front abdomen strap, the ring or the fixing unit being directly coupled to the damping unit in the middle portion, the damping unit connected to the runner by the ring or the fixing unit, and the damping unit comprising a plurality of first layers that are sewn together and are configured to at least partially tear apart in the event of a fall and reduce a loading transferred to a person wearing the harness.

2. The full body harness according to claim 1 wherein the damping unit comprises a plurality of second layers that are woven together and are configured to tear apart in the event of a fall.

3. The full body harness according to claim 1 wherein the damping unit is sewn at seams in at least one of the longitudinal direction and the transverse direction, the seams being configured to at least partially tear apart in the event of a fall.

4. The full body harness according to claim 1 further comprising:
two leg straps coupled to the abdomen strap, and
two shoulder straps coupled to at least one of the front chest strap and the front abdomen strap.

5. The full body harness according to claim 1 wherein the front chest strap has a first ring and the front abdomen strap has a second ring, the damping unit being fixed between the first and second rings.

6. The full body harness according to claim 1 wherein the damping unit extends between the front chest strap and the front abdomen strap such that when worn by a user, the damping unit is located in front of the user's body.

7. The full body harness according to claim 1 , further comprising first and second shoulder straps having ends that are fixed directly to the front chest strap.

8. A harness comprising:
a front chest strap traversing a user's chest substantially horizontally from a right front side of the user to a left front side of the user when worn by the user;
a front abdomen strap traversing the user's abdomen substantially horizontally from a right front side of the user to a left front side of the user when worn by the user, wherein the front abdomen strap traverses the user's abdomen below the front chest strap;
a runner adapted to run in a rail;
a fixing unit coupled to the runner; and
a damping unit having a first end, a second end, and a middle portion between the first and second ends, the first end of the damping unit directly coupled to a middle portion of the front chest strap and the second end of the damping unit directly coupled to a middle portion of the front abdomen strap, the damping unit having a single longitudinal axis extending vertically from the middle portion of the front chest strap and the middle portion of the front abdomen strap, the fixing unit being directly coupled to the damping unit in the middle portion, the damping unit being coupled to the runner by the fixing unit, the damping unit being configured to tear in response to a threshold load being applied to it.

9. The harness according to claim 8 wherein the threshold load is applied to the damping unit when a person using the harness falls while the fixing unit is coupled to the runner.

10. The harness according to claim 8 wherein the damping unit includes a plurality of layers woven together at seams.

11. The harness according to claim 8 further comprising one or more of seams coupling layers of the damping unit together, wherein the one or more seams at least partially tears apart in response to the threshold load being applied to the damping unit.

12. The harness according to claim 8 wherein the first end of the damping unit is coupled to the front chest strap at a first ring, and the second end of the damping unit is coupled to the front abdomen strap at a second ring.

13. The harness according to claim 8 wherein the fixing unit is in a shape of a ring.

14. The harness according to claim 8 wherein the damping unit extends between the front chest strap and the front abdomen strap such that when worn by a user, the damping unit is located in front of the user's body.

15. The harness according to claim 8 , further comprising first and second shoulder straps having ends that are fixed directly to the front chest strap.
