Harness with integrated energy absorber
A fall protection harness for being removably worn by a user having at least two leg straps, a first shoulder strap and a second shoulder strap. At least one of the shoulder straps has an energy absorbing element integrated therewith. The energy absorbing element may be a tubular webbing material surrounding a tearable webbing material with at least two bound webbing components configured to tear from one another when the shoulder strap is subjected to a force that exceeds a predetermined threshold.
1. A wearable harness having a plurality of straps comprising:
a first shoulder strap and a second shoulder strap, wherein at least one of the first shoulder strap and the second shoulder strap is made from a tubular webbing; and
an energy absorbing element integrated with the tubular webbing of at least one of the first shoulder strap and the second shoulder strap,
wherein the energy absorbing element comprises at least two bound webbing components at least partially encased within the tubular webbing,
wherein the at least two bound webbing components have an unbound, starting tear point exposed from the tubular webbing through an opening in the tubular webbing between a first terminal end and a second terminal end of the tubular webbing,
wherein the at least two bound webbing components are configured to tear from one another when the first shoulder strap and the second shoulder strap are subjected to a force that exceeds a predetermined threshold during a fall event, and
wherein a connector element is connected to the at least two bound webbing components at the unbound, starting tear point.
2. The harness of claim 1 , wherein at least a portion of the energy absorbing element is configured to exit through the opening of the tubular webbing upon tearing.
3. The harness of claim 1 , wherein the tubular webbing comprises a substantially flat webbing material having opposing lateral ends connected to one another to define a tubular shape.
4. The harness of claim 1 , wherein the at least two bound webbing components are bound by a plurality of binder threads.
5. The harness of claim 4 , wherein the plurality of binder threads are configured to tear successively in a longitudinal direction of at least one of the first shoulder strap and the second shoulder strap when the at least one of the first shoulder strap and the second shoulder strap is subjected to the force that exceeds the predetermined threshold.
6. The harness of claim 4 , wherein the plurality of binder threads extend through at least a portion of a thickness of the at least two webbing components.
7. The harness of claim 4 , wherein the plurality of binder threads are arranged in two or more substantially parallel or intersecting rows extending along a longitudinal length or a lateral length of the webbing components.
8. The harness of claim 4 , wherein the plurality of binder threads are arranged in two or more thread groups arranged in a pattern and spaced apart from each other along a longitudinal length or a lateral length of the webbing components.
9. The harness of claim 1 , wherein the predetermined threshold is in a range of about 310 lbs to about 2,250 lbs.
10. The harness of claim 1 , wherein the at least two bound webbing components are bound together by an adhesive.
11. The harness of claim 1 , wherein the first shoulder strap and the second shoulder strap have an ending tear point having a reinforced area configured to prevent separation of the at least two bound webbing components.
12. The harness of claim 1 , wherein the energy absorbing element is located on an energy absorbing area at a rear portion of at least one of the first shoulder strap and the second shoulder strap.
13. A fall protection harness removably wearable by a user, the harness having a plurality of straps comprising:
a first shoulder strap and a second shoulder strap is made from a tubular webbing,
wherein at least one of the first shoulder strap and the second shoulder strap have an energy absorbing element integrated with the tubular webbing, the energy absorbing element comprising at least two bound webbing components at least partially encased within the tubular webbing, the at least two bound webbing components bound together by a plurality of binder threads configured to tear successively in a longitudinal direction of the first shoulder strap and the second shoulder strap when the first shoulder strap and the second shoulder strap are subjected to a predetermined force during a fall event,
wherein the at least two bound webbing components have an unbound, starting tear point exposed from the tubular webbing through an opening in the tubular webbing between a first terminal end and a second terminal end of the tubular webbing, and
wherein a connector element is connected to the at least two bound webbing components at the unbound, starting tear point.
14. The harness of claim 13 , wherein the energy absorbing element is located on an area at a rear portion of at least one of the first shoulder strap and the second shoulder strap.
15. In a harness removably attachable to a body of a user and having at least one strap comprising:
an energy absorbing element integrated with a tubular webbing defining the at least one strap,
wherein the energy absorbing element comprises at least two bound webbing components at least partially encased within the tubular webbing of the at least one strap,
wherein the at least two bound webbing components have an unbound, starting tear point exposed from the tubular webbing through an opening in the tubular webbing between a first terminal end and a second terminal end of the tubular webbing,
wherein the at least two bound webbing components are configured to tear from one another when the at least one strap is subjected to a force that exceeds a predetermined threshold during a fall event, and
wherein a connector element is connected to the at least two bound webbing components at the unbound, starting tear point.
