Impact protective multi-layered fabric

Abstract

The disclosure refers to an impact protective multi-layered fabric comprising a pile of layers of a dry-fabric material, wherein at least one of the layers is conformed to have least one closed fold extending longitudinally across the layer, the closed fold having first and second walls substantially facing each other, and wherein the first and second walls are stitched to each other by means of at least one yarn of a dry-fabric material. According to an aspect, the first and second walls of the closed fold, are stitched to each other by means of two or more stitching lines are arranged one above the other within the closed fold, such as when an object impact on the fabric layer, the stitches of the stitching lines break sequentially one after the other, such the energy absorption capability of the layer is increased in a simple manner and without increasing its weight.

What is claimed: 
     
         1 . An impact protective multi-layered fabric, comprising:
 a pile of layers of a textile material, wherein at least one of said layers is conformed to have at least one closed fold extending longitudinally across the layer, wherein said closed fold has a first wall and a second wall substantially facing each other, and wherein said first wall and said second wall are stitched to each other by means of at least one yarn of a textile material.   
     
     
         2 . The impact protective multi-layered fabric of  claim 1 , wherein the first and second walls of the closed fold are stitched to each other by means of at least two stitching lines, wherein each stitching line extends along the closed fold and in major part of the length of the same, and wherein said stitching lines are arranged one above the other. 
     
     
         3 . The impact protective multi-layered fabric of  claim 1 , wherein said at least one layer has at least two closed folds, wherein each closed fold extends longitudinally across the layer, and wherein the at least two closed folds are arranged substantially parallel to each other. 
     
     
         4 . The impact protective multi-layered fabric of  claim 1 , further comprising:
 at least two layers with at least two closed folds, and wherein the closed folds of different layers are arranged one above the other and are aligned.   
     
     
         5 . The impact protective multi-layered fabric of  claim 1 , further comprising:
 at least two layers with at least two closed folds, and wherein the closed folds of different layers are interleaved.   
     
     
         6 . The impact protective multi-layered fabric of  claim 4 , wherein the at least two closed folds are bended such as the first and second walls of each closed fold, are substantially parallel with the layer in which they are formed. 
     
     
         7 . The impact protective multi-layered fabric of  claim 4 , wherein the at least two closed folds are substantially perpendicular to the layer in which they are formed.
