Harness with structural tear tape
A harness configured for being removably attachable to a body of a user has an optional pair of leg straps, an optional belt strap, and a shoulder strap. The shoulder strap has a front portion attached to a front end of each leg strap and a rear portion attached to a rear end of each leg strap. At least a portion of the shoulder strap has an energy absorbing element formed integrally therein having a tearable webbing material with at least two bound, load-bearing webbing components configured to tear from one another.
1. A harness removably attachable to a body of a user, the harness having a plurality of straps, comprising:
a shoulder strap configured to extend over at least a portion of a user's shoulders, the shoulder strap having a first end and a second end fixedly connected to each other to form a continuous loop defining a pair of straps with a front portion of the loop looped through an opening of a front connection element connected to a front portion of a belt strap and a rear portion of the loop looped through an opening of a rear connection element connected to a rear portion of the belt strap,
wherein each of the pair of straps comprises an energy absorbing element formed integrally therewith, the energy absorbing element having 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, and
wherein a first of the at least two bound webbing components of each of the pair of straps is connected to a common anchor element.
2. The harness of claim 1 , wherein the at least two bound webbing components are bound by a plurality of binder threads.
3. The harness of claim 2 , wherein the plurality of binder threads are configured to tear successively in a longitudinal direction of the shoulder strap when the shoulder strap is subjected to the force that exceeds the predetermined threshold.
4. The harness of claim 2 , wherein the plurality of binder threads extend through at least a portion of a thickness of the at least two webbing components.
5. The harness of claim 2 , wherein the plurality of binder threads are arranged in two or more rows extending along a longitudinal length or a lateral length of the webbing components.
6. The harness of claim 5 , wherein the rows are substantially parallel to each other.
7. The harness of claim 5 , wherein the rows intersect with each other at least once over the longitudinal length or the lateral length of the webbing components.
8. The harness of claim 2 , wherein the plurality of binder threads are arranged in two or more thread groups spaced apart from each other along a longitudinal length or a lateral length of the webbing components.
9. The harness of claim 8 , wherein the two or more thread groups are arranged in a pattern.
10. The harness of claim 2 , wherein a density of the plurality of binder threads increases from a rear portion to a front portion of the shoulder strap.
11. The harness of claim 1 , wherein the predetermined threshold is in the range of about 310 lbs to about 2,250 lbs.
12. The harness of claim 1 , wherein the at least two bound, load-bearing webbing components are bound together by an adhesive.
13. The harness of claim 1 , wherein the shoulder strap has a starting tear point at a rear portion where the at least two bound, load-bearing webbing components are unbound.
14. The harness of claim 1 , wherein the shoulder strap has an ending tear point having a reinforced area configured to prevent separation of the at least two bound, load-bearing webbing components.
15. The harness of claim 1 , wherein the energy absorbing element is formed on an energy absorbing area at a rear portion of the shoulder strap.
16. The harness of claim 1 , wherein the anchor element a frame with a first opening for receiving the first of the at least two bound webbing components of each of the pair of straps and a second opening for connecting to a line connected to an anchor point.
17. A harness removably attachable to a body of a user, the harness having a plurality of straps comprising:
a shoulder strap configured to extend over at least a portion of a user's shoulders, the shoulder strap having a first end and a second end fixedly connected to each other to form a continuous loop defining a pair of straps with a front portion of the loop looped through an opening of a front connection element connected to a front portion of a belt strap and a rear portion of the loop looped through an opening of a rear connection element connected to a rear portion of the belt strap,
wherein each of the pair of straps comprises an energy absorbing element formed integrally therewith on an energy absorbing area at the rear portion of the loop, the energy absorbing element having 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,
wherein a first of the at least two bound webbing components of each of the pair of straps is connected to a common anchor element, and
wherein the at least two bound webbing components are bound by a plurality of binder threads configured to tear successively in a longitudinal direction of the shoulder strap when the shoulder strap is subjected to the force.
18. The harness of claim 17 , wherein the shoulder strap has a starting tear area at the rear portion of the loop where the at least two bound webbing components are unbound.
19. At least one strap in a harness removably attachable to a body of a user, the at least one strap comprising:
a shoulder strap configured to extend over at least a portion of a user's shoulders, the shoulder strap having a first end and a second end fixedly connected to each other to form a continuous loop defining a pair of straps with a front portion of the loop configured for being looped through an opening of a front connection element connected to a front portion of a belt strap and a rear portion of the loop configured for being looped through an opening of a front connection element connected to a rear portion of the belt strap,
wherein each of the pair of straps comprises an energy absorbing element formed integrally therewith, the energy absorbing element having 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, and
wherein a first of the at least two bound webbing components of each of the pair of straps is connected to a common anchor element.
20. The strap of claim 19 , wherein the at least two bound webbing components are bound by a plurality of binder threads configured to tear successively in a longitudinal direction of the shoulder strap when the shoulder strap is subjected to the force that exceeds the predetermined threshold.
