Webbing suitable for use in vehicle seat belt system
First Claim
1. In a webbing suitable for use in a vehicle seat belt system, including a laterally-central main portion, and a woven selvedge portion and a knitted selvedge portion which are formed respectively along both side edges of the main portion, the improvement wherein the weave of the main portion comprises a number of wefts composed respectively of first weft threads and second weft threads inserted in pairs, the first weft threads have relatively low bending stiffness and the second weft threads have relatively high bending stiffness, the second weft threads are woven only in the main portion, the first weft threads are contained not only in the main portion but also in the knitted selvedge portion where the first weft threads are intertwined with their corresponding catch threads, which hold their associated wefts and comprise threads having relatively low bending stiffness, to form a hollow selvedge, and the woven selvedge portion forms a hollow selvedge with the first weft threads only.

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.
