Back supporting board

Abstract

A back supporting board includes a hard board, a buffering material, a filling material and an enclosure portion. The front surface of the hard board curves outwards longitudinally and curves inwards transversely. The buffering material and filling material are fitted to the front surface of the hard board. As we rest on the board, our back sinks into the concave region of the hard board and our waist, chest and neck may be supported by the convex region, buffering material and filling material. The sudden motion of our back at the moment we sit and lie back on the board may be buffered by the filling material and buffering material. Therefore, injuries to our back and body may be avoided and discomfort may be alleviated.

 a hard board ( 1 ), having a front surface;   a buffering material ( 2 ), which is fitted on the front surface of the hard board ( 1 ); and   an enclosure portion ( 4 ), which may enclose the buffering material ( 2 ) and hard board ( 1 ).   
     
     
         2 . The back supporting board as in  claim 1 , wherein the front surface of the hard board ( 1 ) curves outwards longitudinally and curves inwards transversely. 
     
     
         3 . The back supporting board as in  claim 1 , wherein the front surface of the hard board ( 1 ) curves inwards longitudinally and transversely. 
     
     
         4 . The back supporting board as in  claim 1 , wherein the buffering material ( 2 ) fully cover the entire front surface of the hard board ( 1 ). 
     
     
         5 . The back supporting board as in  claim 1 , wherein the buffering material ( 2 ) is in the form of rectangular portions, which are spaced apart and provided on the front surface of the hard board ( 1 ). 
     
     
         6 . The back supporting board as in  claim 1 , wherein at least a reinforcement strip ( 12 ) is disposed on the back surface of the hard board ( 1 ) for the purpose of reinforcement of the board. 
     
     
         7 . The back supporting board as in  claim 1 , wherein the buffering material ( 2 ) has small ball-like nipple-shaped protrusions or is in the form of a net. 
     
     
         8 . A back supporting board, comprising:
 a hard board ( 1 ), having a front surface, wherein a buffering material ( 2 ) and a filling material  3  are fitted on the front surface of the hard board ( 1 ); and   an enclosure portion ( 4 ), which may enclose the buffering material ( 2 ), filling material ( 3 ) and hard board ( 1 ).   
     
     
         9 . The back supporting board as in  claim 8 , wherein the front surface ( 11 ) of the hard board ( 1 ) curves outwards longitudinally and curves inwards transversely. 
     
     
         10 . The back supporting board as in  claim 8 , wherein the front surface ( 11 ) of the hard board ( 1 ) curves inwards longitudinally and transversely. 
     
     
         11 . The back supporting board as in  claim 8 , wherein at least a reinforcement strip ( 12 ) is disposed on the back surface of the hard board ( 1 ) for the purpose of reinforcement of the board. 
     
     
         12 . The back supporting board as in  claim 8 , wherein the area not covered by the buffering material ( 2 ) is covered by the filling material ( 3 ) so as to cover the entire area of the front surface ( 11 ) of the hard board ( 1 ). 
     
     
         13 . The back supporting board as in  claim 8 , wherein the buffering material ( 2 ) is in the form of rectangular portions, which are spaced apart and provided on the front surface of the hard board ( 1 ), and the area not covered by the buffering material ( 2 ) is covered by the filling material ( 3 ). 
     
     
         14 . The back supporting board as in  claim 8 , wherein a layer of the filling material ( 3 ) that fully covers the front surface is first fitted to the front surface ( 11 ) of the hard board ( 1 ) and a buffering material ( 2 ) with the same size is then fitted to the filling material ( 3 ). 
     
     
         15 . The back supporting board as in  claim 8 , wherein a layer of the filling material ( 3 ) that fully covers the front surface is first fitted to the front surface ( 11 ) of the hard board ( 1 ) and the buffering material ( 2 ) in the form of rectangular portions is then fitted to the filling material ( 3 ). 
     
     
         16 . The back supporting board as in  claim 8 , wherein a layer of the filling material ( 3 ) that fully covers the front surface is first fitted to the front surface ( 11 ) of the hard board ( 1 ) and a buffering material ( 2 ) with the same size is then fitted to the filling material ( 3 ) and then a layer of the filling material ( 3 ) with the same size is fitted to the buffering material ( 2 ). 
     
     
         17 . The back supporting board as in  claim 8 , wherein a plurality of support units or portions made of the buffering material ( 2 ) are spaced apart and fitted to the filling material ( 3 ). 
     
     
         18 . The back supporting board as in  claim 8 , wherein a plurality of support units with a certain thickness are formed by the combination of the buffering material ( 2 ) and the filling material ( 3 ) and these support units are spaced apart and disposed on the front surface ( 11 ) of the hard board ( 1 ).
