Abstract:
1. A woven webbing for an automotive seat belt comprising: a first group of nonconductive warp threads having a first extensibility; and a second group of nonconductive warp threads having a second extensibility, the first extensibility being greater than the second extensibility; wherein at least one warp thread of the first group of warp threads includes an electrical conductor concealed in an interior of the woven webbing that electrically connects with an electronic device that is ultrasonic or laser welded to the first group of warp threads; and wherein the greater extensibility of the first group of warp threads compensates for any weakening of tensile strength due to the welding of the electronic device, such that when the first and second groups of warp threads are exposed to tensile stress all of the threads therein counter the tensile force substantially uniformly.
