ABSTRACT:
A tear webbing includes two woven straps each having a first length portion and an adjoining second length portion. The woven straps are, along the first length portion, in a parallel, superposed orientation and in a face-to-face engagement with one another and a binding yarn connects the woven straps to one another along the first length portion. The woven straps which are separate from one another along the second length portion are adapted to be exposed, in the second length portion, to pulling forces causing a progressive separation of the woven straps along the first length portion under an irreversible energy absorption. The tear webbing further includes an elastic coating matrix in which the woven straps are at least partially embedded along the first length portion.
