Abstract
A continuously woven web includes a first woven region interwoven with a plurality of yarns to define a first weave pattern and a second woven region forming a continuous weave with the first woven region and having a continuation of the yarns. The yarns are attached to the second woven region at a distal end thereof. The second woven region has a length defined by a length between a first end positioned adjacent a termination of the first weave pattern and the distal end. In the second woven region, the yarns have a greater elasticity in aggregate and a shorter length than the second woven region. Upon application of a tensile force to the webbing, the yarns in the second woven region may elongate to a length limited by the length of the second woven region.
Claims15
A woven webbing comprising:
- a first woven region woven region woven with a first set of yarns and interwoven with a second set of yarns to define a first weave pattern;
- and,
- a second woven region woven with said first set of yarns to form a continuous weave with said first woven region woven with said first set of yarns and having a continuation of said second set of yarns, said second set of yarns being attached to said second woven region woven with said first set of yarns at a distal end of said second woven region, with said second woven region woven with said first set of yarns having a length defined by a length between a first end positioned adjacent a termination of said first weave pattern and said distal end,
- wherein, in said second woven region, said second set of yarns has a shorter length than said second woven region woven with said first set of yarns such that, upon application of a tensile force to said webbing, said second set of yarns in said second woven region may elongate to a length limited by the length of said second woven region woven with said first set of yarns.
A lanyard with continuous, partially oriented yarns that serve as binders for a flat part of the lanyard and stuffers for a tubular part of the lanyard, a portion of the tubular part being inverted, doubled upon itself to form a double layer portion connected to and surrounding a portion of the flat part, whereby application of a tensile force to the lanyard causes the partially oriented yarns in the tubular part to stretch, enabling the double layer portion to undouble and form a single layer tube.
A lanyard with continuous, partially oriented yarns that serve as relatively tight binders for a flat part of the lanyard, stuffers for a tubular part of the lanyard and relatively loose binders for an intermediate part of the lanyard, the intermediate part alternately folding back upon itself in a serpentine manner to define an alternately folded portion having a longitudinal axis, the partially oriented yarns loosely weaving through the intermediate part substantially along the axis, whereby application of a tensile force to the lanyard causes the partially oriented yarns in the intermediate part and the tubular part to stretch, enabling the alternately folded portion to unfold.
