Mattress for bed frame with bow structure

Abstract

A mattress for bed frame with bow structure includes a fixed seat and multiple of arc-shaped elastic rods, the mattress is formed by staggered connection of horizontally arranged weft lines and longitudinally arranged warp lines, and the weft lines are unevenly distributed in high-density regions and low-density regions; the multiple of arc-shaped elastic rods are sequentially installed side by side on the fixed seat and in the same direction as the weft lines; the free ends of each of the arc-shaped elastic rods are connected on the edge of the mattress to tension and set up the mattress above the arc-shaped elastic rods. When a user sits on or lies on the mattress, an region of the mattress bearing weight matches the shape of a use's body in contact with the mattress to deform, thereby providing good elastic support for each part of the body.

What is claimed is: 
     
         1 . A mattress for bed frame with bow structure, comprising a fixed seat and multiple of arc-shaped elastic rods, said mattress is formed by staggered connection of horizontally arranged weft lines and longitudinally arranged warp lines, and said weft lines are unevenly distributed in high-density regions and low-density regions; said multiple of arc-shaped elastic rods are sequentially installed side by side on said fixed seat in a same direction as said weft lines; free ends of each of said arc-shaped elastic rods are respectively directly or indirectly connected on opposite edges of said mattress to tension and set up said mattress above said arc-shaped elastic rods. 
     
     
         2 . The mattress for bed frame with bow structure according to  claim 1 , wherein each of said high-density regions is composed of at least two of said weft lines side by side, each of said low-density regions is blank regions, or is composed of at least one of said weft lines and blank regions on both sides thereof, or said low density region is composed of several weft lines and said blank regions on both sides of each of said weft lines. 
     
     
         3 . The mattress for bed frame with bow structure according to  claim 2 , wherein a diameter of each of said weft lines is 0.04-2 mm, a width of each of said blank regions is 0.2-2 mm; said diameter of each of said weft lines is 2-100 times of that of each of said warp lines. 
     
     
         4 . The mattress for bed frame with bow structure according to  claim 1 , wherein said weft lines and said warp lines are both made of Teslin. 
     
     
         5 . The mattress for bed frame with bow structure according to  claim 1 , wherein said width of each of said high-density regions is equal or unequal to each other, while said width of said low-density regions is equal or unequal to each other. 
     
     
         6 . The mattress for bed frame with bow structure according to  claim 1 , wherein said warp lines distributes evenly or unevenly, a distance of said adjacent warp lines is 0.2-5 mm; said adjacent warp lines pass above or under each of said weft lines respectively. 
     
     
         7 . The mattress for bed frame with bow structure according to  claim 1 , wherein both edges of said mattress are sewn with reinforcement lines. 
     
     
         8 . The mattress for bed frame with bow structure according to  claim 1 , wherein said fixed seat includes two side rods; said free ends of all of said arc-shaped elastic rods are fixed on said side rods respectively, said opposite edges of said mattress are connected with said two side rods respectively. 
     
     
         9 . The mattress for bed frame with bow structure according to  claim 8 , wherein each of said edges wounds around one of said side rods and passes through joint points of said free ends and said side rods. 
     
     
         10 . The mattress for bed frame with bow structure according to  claim 8 , wherein each of said edges is folded to form a double-layer structure; said double-layer structure wounds one of said side rods and passes through joint points of said free ends and said side rod; said double-layer structure is provided with a limiting hole above said arc-shaped elastic rods, a inserting rod is inserted said limiting hole and against said arc-shaped elastic rods across one side of said double-layer structure, thereby fixing said edge.
