Webbing roller

Abstract

A webbing roller suitable for being coupled to a portion of a webbing, drooping after an effective length of the webbing is adjusted. The webbing roller includes a pair of webbing roller bodies; an opening defined at first ends of the webbing roller bodies and having a retainer band which is connected to the first ends of the webbing roller bodies around the opening; and a fastening projection formed on second ends of the webbing roller bodies to allow the retainer band to be fastened thereto.

1 . A webbing roller comprising:
 a pair of webbing roller bodies formed parallel to each other;   a first wing and a second wing formed on both ends of the webbing roller bodies to be parallel to each other;   an opening defined at a side of the first wing such that a retainer band can be connected to the first wing around the opening; and   a fastening projection formed at a side of the second wing such that the retainer band connected to the first wing around the opening can be fastened to the fastening projection.   
   
   
       2 . The webbing roller according to  claim 1 , wherein a slit is defined between the pair of webbing roller bodies which are formed parallel to each other. 
   
   
       3 . The webbing roller according to  claim 1 , wherein depressions and prominences are formed on the webbing roller bodies so as to prevent a webbing from slipping on the webbing roller bodies. 
   
   
       4 . The webbing roller according to  claim 1 , wherein the pair of webbing roller bodies are formed to be placed at positions which are separated by a predetermined distance from both ends of the first wing and the second wing such that the first wing and the second wing can perform a guiding function when the webbing is wound around the pair of webbing roller bodies. 
   
   
       5 . The webbing roller according to  claim 1 , wherein the opening is defined outside a middle portion of the first wing, and first protrusions are formed on the middle portion of the first wing in such a way as to protrude sideward between first ends of the pair of webbing roller bodies. 
   
   
       6 . The webbing roller according to  claim 5 , wherein the first protrusions are formed to have a height of 1.5˜2.5 mm, preferably, 1.7˜1.8 mm, when measured from outer surfaces of the pair of webbing roller bodies. 
   
   
       7 . The webbing roller according to  claim 1 , wherein the fastening projection is formed on a middle portion of the second wing, and second protrusions are formed on the middle portion of the second wing in such a way as to protrude sideward between second ends of the pair of webbing roller bodies. 
   
   
       8 . The webbing roller according to  claim 7 , wherein the second protrusions are formed to have a height of 1.5˜2.5 mm, preferably, 1.7˜1.8 mm, when measured from the outer surfaces of the pair of webbing roller bodies. 
   
   
       9 . The webbing roller according to  claim 1 , wherein the retainer band is made of an elastic material. 
   
   
       10 . The webbing roller according to  claim 1 , wherein the fastening projection is formed to have a neck part which has a reduced thickness so as to allow the retainer band connected to the first wing around the opening to be fastened to the neck part of the fastening projection.
