Abstract
A shock absorbing lanyard having an integral fall arrest energy absorber formed in a one-piece woven, knitted or braided construction wherein partially oriented yarn (“POY”) fibers and high modulus yarn fibers are combined integrally in one section and are separate in another section in which the high modulus yarn fibers preferably form a sheath around a core of POY fibers.
Claims16
A shock absorbing lanyard that will deploy in response to a force of between 450 lbs. and 900 lbs., the lanyard comprising;
- a one piece webbing including partially oriented yarn fibers and high strength yarn fibers, the partially oriented yarn fibers being adapted to elongate under the force applied to the shock absorbing lanyard and to absorb energy;
- a first section of the one piece webbing, the partially oriented yarn fibers and the high strength yarn fibers being integrally assembled in the first section by one of weaving, knitting and braiding;
- and
- a second section of the one piece webbing, the partially oriented yarn fibers and the high strength yarn fibers being separately assembled in the second section, the high strength yarn fibers forming a sheath around the partially oriented yarn fibers in the second section.
A multi-leg shock-absorbing lanyard that will deploy in response to a force of between 450 lbs. and 900 lbs., the multi-leg lanyard comprising:
- a plurality of legs, each leg comprising a one-piece webbing including partially oriented yarn fibers and high-strength yarn fibers, the partially oriented yarn fibers being adapted to elongate under the force applied to each leg of the multi-leg shock absorbing lanyard and to absorb energy;
- a first section of the one piece webbing, the partially oriented yarn fibers and the high strength yarn fibers being integrally assembled in the first section by one of weaving, knitting and braiding;
- and
- a second section of the one piece webbing, the partially oriented yarn fibers and the high strength yarn fibers being separately assembled in the second section, the high strength yarn fibers forming a sheath around the partially oriented yarn fibers in the second section.
A harness including a shock absorbing lanyard that will deploy in response to a force of between 450 lbs. and 900 lbs., the shock absorbing lanyard comprising;
- a one piece webbing including partially oriented yarn fibers and high strength yarn fibers, the partially oriented yarn fibers being adapted to elongate under the force applied to the shock absorbing lanyard and to absorb energy;
- a first section of the one piece webbing, the partially oriented yarn fibers and the high strength yarn fibers being integrally assembled in the first section by one of weaving, knitting and braiding;
- and
- a second section of the one piece webbing, the partially oriented yarn fibers and the high strength yarn fibers being separately assembled in the second section, the high strength yarn fibers forming a sheath around the partially oriented yarn fibers in the second section.
