Abstract A seamless combined vehicle safety shoulder and waist belt has a shoulder section which is plastically elongatable and of high energy absorption, and a waist section of high tensile strength. The shoulder section is thinner than the waist section, the shoulder section including weft interwoven warps and linear core warps enclosed between the opposite faces of the shoulder section, and the waist section includes all of the shoulder section warps and additional warps, all the waist section warps being interwoven with wefts. In producing the belt, it is continuously woven with successive alternate waist and shoulder sections, the warps which form the waist sections and not in the shoulder sections floating in the shoulder sections and being thereafter severed proximate the areas of junction.
A combined vehicle safety belt shoulder and waist section structure in which said shoulder and waist sections are woven of warps and wefts and possess different strength and elongation properties characterized in that said shoulder and waist sections possess a plurality of common continuous warps with some of said warps in said waist section being discontinued in said shoulder section and said waist section possessing a greater number of warps than said shoulder section and at least some of said common continuous warps possessing high non-recoverable high energy absorbing properties and at least some of said high non-recoverable high energy absorbing warps in said waist section interwoven with wefts therein extending through said shoulder section as core yarns unwoven with wefts in said shoulder section.
