It can be the connection between two elements or the interaction between two elements. For those skilled in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0040] In one embodiment in the present invention, as shown in FIG. 4-7, the mattress 100 for bed frame with bow structure, which includes fixed seat 300 and multiple of arc-shaped elastic rods 200, the mattress 100 is formed by staggered connection of horizontally arranged weft lines 101 and longitudinally arranged warp lines 102, and the weft lines 101 are unevenly distributed in high-density regions 100a and low-density regions 100b. The multiple of arc-shaped elastic rods 200 are sequentially installed side by side on the fixed seat 300 in the same direction as the weft lines 101. The free ends of each of the arc-shaped elastic rods 200 are directly or indirectly connected with the edge of the mattress 100 to tension and set up the mattress 100 above the arc-shaped elastic rods 200.

[0041] When a user sleeps or sits on the mattress 100, the mattress 100 bears the weight of the user to deform and pull directly or indirectly the free ends 201 of each of the arc-shaped elastic rods 200, causing the arc-shaped elastic rods 200 to deform and store elastic potential energy, and the two free ends 201 to be relatively closed, so that the mattress 100 to deform from a flat state into a downward depression state. The region of the mattress 100 directly bearing the weight of the user, that is directly contacting with the body of the user, is concave downward, the weft lines 101 and the warp lines 102 passing through the region pull the weft lines 101 and warp lines 102 in other regions and connected thereto, causing interference between each other, resulting in corresponding concave deformation in the other regions as well. The concave range of the region of the matress100 directly bearing the weight is related to the magnitude of the weight borne. The greater the weight borne, the greater the concave range. The smaller the weight borne, the smaller the concave range. The concave range of the other regions, that have interference effects with the region of the matress100 directly bearing the weight, is also the same. In addition, the deformation of the mattress 100 is also defined by the body shape of the user, and its concave curve matches the body shape of the user.

[0042] Referring to FIG. 5, in the invention, the warp lines 101 are arranged in high-density regions 100a and low-density regions 100b unevenly, that is in the low-density regions, the number of the warp lines is reduced, thereby in some degree reducing the interfere effect, and reducing the concave rang caused by interference in the other regions connected to the region of the mattress directly bearing the weight. When the user sleeps on the mattress, the user's leg, buttocks, waist, back will apply pressure corresponding to their weight to the regions of the mattress directly contacting, resulting in corresponding degree of concave deformation. At the same time, due to the small interfere effect of these stressed regions and the other regions, the concave rang of each of the stressed regions is basically adapted to the pressure it is suffered.

[0043] Referring to FIG. 3, when user's lies on his back on the mattress 100, in the normal body curve, the buttocks and the back protrude from the waist, and the weight of these two parts is greater than the waist, causing the region of the mattress supporting the buttocks and the back to deform and depress significantly under pressure, so that the region corresponding to the waist can just fit tightly the waist and support it, thereby avoiding the waist from hanging in the air. When the user's sleeping position changes, for example, from lying on the user's back to lying on the user's side, the regions of the user's body contacting the mattress are changed, resulting in that the mattress is changed in corresponding deformation to adapt to the user's body shape, providing better supporting to the user's body.

[0044] The mattress 100 can adapt to the weight and the body of the user and deform accordingly, thereby providing elastic support for the user's body, greatly improving comfort, and preventing body diseases such as lumbar spondylosis caused by poor sleeping posture.

[0045] Referring to FIG. 5, each of the high-density regions 100a is composed of at least two of the weft lines 101 side by side. The number of the warp lines 101 of each of the high-density regions is preferably 3-10. In the high-density regions 100a, the adjacent warp lines 101 are side by side, when bearing weight, they interfere with each other and share weight, thereby reducing the pressure borne by each weft line.

[0046] It should be understood that the interfere of the regions of the mattress 100 directly contacting with the user's body and the other regions of the mattress 100 not contacting with the user's body is realized by the weft lines and the warp lines passing each of the regions and swagged connection. For reducing the interfere, the low-density regions may be blank regions. On this occasions, both sides of the high-density regions are blank regions. When the high density regions bears weight to deform, the weft lines 101 in this high density regions interfere the weft lines 101 and the warp lines 102 connected with them but not bearing weight in the other regions, causing them to deform. The black regions 102a have no the weft lines 101, it can not interfere the other regions by the swagged connection of the weft lines 101 and the warp lines 102, and the number of the warp lines 102 connected the weft lines 101 in this regions is less, although the interfere effect can be caused by the swagged connection of the warp lines 102 passing through this high-density regions and the weft lines 101 and the warp lines 102 passing the other high-density regions, the interfere effect is greatly reduced, thereby each of the regions of the mattress 100 can adapt relatively independently to the weight and the shape of the user it contacted and deform. It should be understood that the low-density regions may be composed of at least one of the weft lines and its blank regions on both sides, or the low density region is composed of several weft lines and the blank regions on both sides of each of the weft line. In addition, since the number of the weft lines 101 in the high-density regions is relatively larger than that of the weft lines 101 in the low-density regions, the knitting density of the high-density region 100a is higher than that of the low-density region 100b, the high-density regions 100a is stronger, and can improve the supporting force of the mattress 100, thereby providing a wider range of application. The low density region 100b, however, has blank regions. Compared with the high-density region 100a, the low density region 100b has a low weaving density, is easy to stretch and deform, has a better air permeability, can improve the self-adaptive performance of the mattress 100, better fits the user's body, can also improve the overall air permeability of the mattress, and improves the comfort of the user.

[0047] The diameter of each of the weft lines 101 is 0.04-2 mm, the width of each of the blank regions is 0.2-2 mm; the diameter of each of the weft lines 101 is 2-100 times of that of each of the warp lines 102. The weft lines and the warp lines are both made of Teslin. The diameter of the weft lines 101 is larger than that of the warp lines 102, the two has the same material, thereby that the warp line 102 has better deformation resistance than weft lines 101, while the weft lines 101 are relatively easily to deform. When the user sleeps on the mattress, the mattress bears the weight of the user and is easy to be deformed and depressed along the direction of the warp lines 102, however it is relatively difficult to be deformed and depressed along the direction of the weft lines 101, although the weft lines 101 are depressed together with the warp lines 102, thereby providing the user with a good support.

[0048] The widths of the high-density regions 110a are equal or unequal, while the widths of the low-density regions 100b are equal or unequal. It should be understood that the widths of the high-density regions 110a and that of the low-density regions 100b can be arranged according to the weight of the body parts of the user, for example. the waist is more weight than the leg, therefor, the high-density regions 110a corresponding to the waist should be wider, the low-density regions 110b corresponding to the waist should be more narrow.

[0049] It should be understood that the wider the high densityregions100 are, the worse the self-adaptive effect of the mattress is, the more difficult it is to deform according to the shape of the user's body, and the stiffer the mattress is perceived by the user. The more the low density regions 100b are, the easier the mattress is deformed, the better the self-adaptation is, and the softer the mattress is. The widths of the high density regions 100a and the low sealing regions 102 may also be adjusted according to requirements during production, so as to adjust the self-adaptation effect and the softness of the mattress 100.

[0050] Preferably, the weft lines 101 and the warp lines 102 are both made of Teslin.

[0051] The warp lines 102 distributes evenly or unevenly, the adjacent warp lines 102 pass above or under each of the weft line 101 respectively. The distance of the adjacent warp lines is 0.2-5 mm. The distance of the adjacent warp lines is greater than the distance of the adjacent weft threads, especially greater than the distance of the adjacent weft threads in the high-density regions. The sparse arrangement of the warp lines 102 also aims to increase the deformation degree of the mattress in the direction of the warp line, so that when the user sleeps on the mattress, the mattress can adapt to the user's body to be deformed, and the deformation degree in direction of the warp lines is greater 4 than that in the direction of the weft lines, especially that in the high-density regions, thereby better supporting the user's body.

[0052] Both side edges of the mattress are sewn with reinforcement lines. The reinforcement lines avoids the weft lines 101 from being spread out after the warp lines 102 are broken so that the mattress is more durable.

[0053] Referring to FIG. 6 and FIG. 7, the fixed seat 300 includes two side rods 301. The free ends 201 of all of the arc-shaped elastic rods 200 are fixed on the side rods 301 respectively, the opposite side edges 103 of the mattress 100 are connected with the two side rods 301 respectively.

[0054] Each of the side edges 103 pf the mattress 100 wounds around one of the side rods 301 and passes through joint points of the free ends 201 and the side rods 301.

[0055] Each of the edge sides 103 is folded to form a double-layer structure, wounding one of the side rods 301 and passes through the joint points of the free ends 201 and the side rods 301. The double-layer structure is provided with a limiting hole 104 above the arc-shaped elastic rods 200, the inserting rod 105 is inserted the limiting hole 104 and against all of the arc-shaped elastic rods 200 across one side of the double-layer structure, thereby fixing the side edge 103.

[0056] Preferably, each of the side rods 301 is provided with multiple of insertion tubes, the insertion tubes 302 correspond to the free ends 201 of the arc-shaped elastic rods 200, and each of the free ends 201 is inserted into one of the insertion tubes 302.

[0057] The arc-shaped elastic rods 200 are arranged in parallel sequentially, and a transparent glass fibre tube is sheathed outside of each of the arc-shaped elastic rods 200.

[0058] In an embodiment in the invention, referring to FIG. 8 and FIG. 9, a mattress with bow structure includes a mattress 400 and multiple of arc-shaped elastic rods 500, the mattress 400 is set above the multiple of arc-shaped elastic rods 500.

[0059] The mattress 400 is composed by alternately connecting multiple of high density regions 400a and multiple of low density regions 400b, including a plurality of transversely arranged woven belts 410 and a plurality of vertically arranged connection belts 420. The plurality of woven belts 410 are arranged side by side in parallel.

[0060] The woven belts 410 are corresponding with the arc-shaped elastic rods 200 one by one, both ends of each of the woven belts 410 are fixed with both ends of the arc-shaped elastic rods 500 respectively corresponding to it, thereby setting up the woven belts 410 above the arc-shaped elastic rods 500.

[0061] Preferably, referring to FIG. 2, the adjacent woven belts 410 are arranged in close proximity, so that the surface of the mattress 400 forms a plane, thereby better preventing the foot from being injured due to the user's denting.

[0062] The woven belts 410 are in the high density regions 400a, the space between the adjacent woven belts 410 are in the low density regions 400b. When the user sleeps on the mattress 400, the mattress 400 are self-adaptive to deform according the the body curve of the user, the woven belts 410 and the connection belts 420 are interfered with each other. The low density regions 400b has lower density and a better air permeability than the high density regions 400a, so that the overall air permeability of the mattress 400 and the comfort of a user can be improved. The high-density regions 400a has a relatively high knitting density, and is more robust than the low-density region 400b. The high-density region 400a increases a supporting force of the mattress 400, thereby applying in a wider range.

[0063] The width of the high density regions 400a and that of the low density regions 400b can be adjusted according the user's requirement.

[0064] The width of the high density regions 400a and that of the low density regions 400b are equal or unequal, the width of each of the high density regions 400a is equal or unequal, the width of each of the low density regions 400b is equal or unequal.
