Patent attributes
The disclosed webbing for a passenger restraint belt may include warp yarns and weft yarns made of synthetic filaments and woven so as to extend orthogonally to each other. At least one of the warp yarns and the weft yarns may be formed using synthetic filaments comprising first filaments and second filaments. Also, the second filaments may be provided in the first filaments and have a melting temperature lower than that of the first filaments. The synthetic filaments may be high shrinking synthetic filaments which are contracted at a dimensional shrinkage rate of 20% to 60% after the second filaments are melted under conditions of 150° C. or more for 180 seconds or more. The webbing may have a weight of 60g/m or less, a tensile strength of 25 kN or more, and a retention rate after hexagonal bar abrasion of 70% or more.
