Webbing is formed by weaving wefts and warps of high extensibility and has warp threads of low or medium extensibility suitably spaced apart in the widthwise direction of the webbing and woven into the webbing to form energy absorbing portions.
Claims2
An energy-absorbing webbing for seat belts of at least double weave structure comprising first wefts of high extensibility, second wefts of water-soluble threads to be removed after weaving the webbing, the first and second wefts being alternately arranged, first warps of high extensibility interlaced with the first wefts, and second warps selected from threads of low and medium extensibility and woven to be interlaced with only the second wefts, whereby after removal of said second wefts said second warps are in undulated structure in the direction of the thickness of the webbing.
An energy-absorbing webbing for seat belts at least double weave structure comprising first wefts of high extensibility, second wefts readily breakable upon exertion of a predetermined load thereon, the first and second wefts being alternately arranged, first warps of high extensibility interlaced with the first wefts, and second warps selected from threads of low and medium extensibility and woven to be interlaced with only the second wefts.
