Abstract: A solid-color weave pattern belt comprising a weave in which warps are arranged at such a high density that wefts are substantially hidden behind the warps. The weave comprises a 2/2 twill weave having four warp threading phases with warp threading arrangement units selected from three kinds of units formed by omitting one to three warp threading phases from the four warp threading phases. A plurality of at least one warp threading arrangement units are successively adjacent to each other, thereby forming an uneven weave pattern of wefts substantially hidden behind the warps on the surface of the belt.

Abstract: A webbing suitable for use in a vehicle seat belt system includes wefts, each of which is composed in combination of a first weft thread having low bending stiffness and a second weft thread having high bending stiffness. Owing to the inclusion of the second weft threads, the webbing of this invention is resistant to lateral, i.e., widthwise flexure. Accordingly, there is a smaller danger for the webbing of this invention to develop jamming or turning-over when caused to extend through its associated through-anchor.
