Referring to fig. 1, 2, 3 and 4, a cushion support structure 100 includes a holder 110a and a plurality of adaptive units 120 integrally disposed side by side on the holder. Each of the adaptive units 120 includes a flexible carrier 121 and an elastic member 130; the elastic member 130 supports the flexible carrier 121 to be tensioned. Each of the elastic members 130 has two symmetrical rod ends 131, and the flexible bearing member 121 is fixedly connected with the rod ends 131. The flexible bearing part 121 is deformed by pressure, and pulls the rod end 131 of the elastic part 130 connected with the flexible bearing part to relatively deflect and fold, so that the elastic part 130 is deformed; when the pressure is removed, the elastic member 130 is restored, and the flexible carrier 121 is tensioned again.

It should be understood that the term "tension" as used herein means that the elastic member 130 supports the flexible carrier 121 in a stretched and tensed state, as shown in fig. 5, or in a natural state under tension, and exhibits a slightly sagging arc, as shown in fig. 6. In particular, when the flexible carrier 121 is an elongated flexible strap 121a or a block-shaped flexible braid 121b, the term "tension" in this application may be a stretched and taut state as shown in fig. 5, or may exhibit a natural downward curvature as shown in fig. 6.

In some embodiments of the present invention, as shown in fig. 5, the elastic member 130a is an elastic rod formed by integrally molding two rod ends 131a and an arc-shaped rod body 132 a. The elastic member 130a in this embodiment forms the adaptive unit 120a in an "arch" shaped structure together with the elongated flexible strap 121 a. Referring to fig. 7, the change state of the adaptive unit after being stressed is shown by a dotted line. When the strap 121a is pressed, for example, when a human body presses on the strap 121a, the strap 121a is sunken and deformed towards the direction of the elastic rod, and generates a radian adaptive to the human body, and simultaneously, the rod end 131a is pulled to deviate and approach towards the center direction of the arch, the middle part of the elastic rod is sunken further, and an effect of adapting to a physiological curve of the human body is formed, so that the physiological curve of the human body is improved, and lumbar spondylosis and the like are prevented or improved. When the human body leaves the strap 121a, the pressure is removed, the elastic rod is restored, and the strap 121a is restored to the original state.

It is understood that the elastic member 130a may also be used in cooperation with the block-shaped flexible braid 121b, as shown in fig. 2. In this case, one of the block-shaped flexible braids 121b is engaged with a plurality of elastic members 130 a. When the block-shaped flexible knitted fabric 121b is pressed, for example, a human body presses thereon, the block-shaped flexible knitted fabric 121b deforms to be concave towards the elastic member 130a, and generates an arc adaptive to the human body, and simultaneously pulls all the rod ends 131a connected with the block-shaped flexible knitted fabric to deviate towards the center direction of the elastic member 130a, and the middle part of the elastic member 130a is further concave. When the human body leaves the block-shaped flexible braid 121b, the pressure is removed, all the elastic members 130a are restored, and the block-shaped flexible braid 121b is restored to the original state. In this embodiment, the number of the elastic members 130a is determined according to the size of the braid 121 b.

In some embodiments of the present invention, referring to fig. 8, the elastic member 130b may also be two elastic rods formed by integrally molding the rod end 131b and an arc-shaped or straight rod body 132b, and the two elastic rods are symmetrically mounted on a mounting member 133. The mounting member 133 may be a straight bar, or a plate, or a frame. The structure of the invention is not limited uniquely, and the structure can meet the requirement that the elastic rods can be symmetrically arranged and can not easily shake relative to the ground. The elastic member 130b may also be used in cooperation with the elongated flexible band 121a or the block-shaped flexible braid 121b, respectively. It should be understood that when the elastic member 130b is used with the elongated flexible strip 121a, only one pair of symmetrical elastic rods need to be mounted on the mounting member 133, and when the elastic member 130b is used with the block-shaped flexible braid 121b, several pairs of symmetrical elastic rods need to be mounted on the mounting member 133.

In some embodiments of the present invention, referring to fig. 9, the elastic member 130c is formed by two arc-shaped rods 132c arranged in parallel, and two side ends of the two arc-shaped rods 132c are respectively connected to form the rod end 131c. The elastic member 130c may also be used in cooperation with the elongated flexible band 121a or the block-shaped flexible braid 121b, respectively. When the elastic member 130b is used in cooperation with the elongated flexible strip 121a, one elongated flexible strip 121a only needs to be used in cooperation with one elastic member 130 c. When the elastic member 130c is used with the block-shaped flexible braid 121b, one block-shaped flexible braid 121b needs to be used with a plurality of elastic members symmetrically arranged.

In some embodiments of the present invention, referring to fig. 10, the elastic member 130d is formed by two U-shaped members mounted on a mounting member, the U-shaped members are two arc-shaped rods 132d arranged in parallel, one end of each arc-shaped rod is connected to form the rod end 131d, and the two U-shaped members are symmetrically arranged on the mounting member 133. The elastic member 130d may also be used in cooperation with the elongated flexible band 121a or the block-shaped flexible braid 121b, respectively. When the elastic member 130d is used in cooperation with the elongated flexible strip 121a, one elongated flexible strip 121a only needs to be used in cooperation with one pair of the rod ends 131 d. When the elastic member 130d is used with the block-shaped flexible braid 121b, one block-shaped flexible braid 121b is used with a plurality of pairs of the rod ends 131 d.

In some embodiments of the present invention, referring to fig. 11 and 12, the elastic member 130e is an arc-shaped plate 132e, and both ends of a plurality of the elongated flexible bands 121a are loaded on the edge of the arc-shaped plate 132e, or the edge of the block-shaped flexible braid 121b is loaded on the edge of the arc-shaped plate 132 e.

In some embodiments of the present invention, the elastic member 130 and the flexible carrier 120 are fixedly connected or fixedly connected through a connecting member 150. The fixed connection of the two can be achieved by fixing the end or edge of the flexible carrier 120 to the rod end 131. Specifically, in some embodiments, the strap 121a is directly tied to the rod end 131, or a lace is provided at an edge of the block-shaped flexible braid 121b, and is tied to the rod end 131 through the lace. In some embodiments, a through hole or a groove is formed in the rod end 131, and when the flexible carrier 120 is the elongated flexible strap 121a, an end of the strap 121a is threaded through the through hole or the groove and then stitched on itself to form a buckle. When the flexible carrier 120 is a block-shaped flexible braided fabric 121b, a ring buckle made of a flexible braided fabric material is arranged at the edge of the flexible carrier, and the ring buckle penetrates through the through hole or the groove to realize fixed connection. In some embodiments, the flexible carrier 120 and the rod end 131 are fixedly connected by the connecting member. Preferably, the connecting member is preferably fixed to the rod end 131, which in turn connects to the flexible carrier 120. The connecting member should provide a structure that facilitates the fixed connection of the flexible carrier 120, such as a groove or a through hole, or other structures that facilitate the connection of the flexible carrier 120.

Preferably, in some embodiments of the present invention, the rod end 131 has a circular cross-section, and more preferably, an oval, square, rectangular, or polygonal cross-section, so as to prevent the elastic member 130 from rotating or shaking about itself when the elastic member 130 is pulled by the flexible carrier 120.

Preferably, in some embodiments of the present invention, the cross-section of the rod body is circular, and more preferably, is oval, square, rectangular, or polygonal, so as to prevent the elastic member 130 from rotating or shaking around itself when the elastic member 130 is pulled by the flexible carrier 120.

In some embodiments of the present invention, the elastic member 130 is made of epoxy resin fiber, aluminum alloy, carbon fiber, aircraft aluminum, glass reinforced fiber, and spring steel, which have a certain degree of elasticity and bending strength, and can deform under a force and recover to its original shape after the force is removed. The elasticity of the elastic part is 300N-10000N. The elasticity of the elastic piece is flexibly set according to objective requirements.

In some embodiments of the present invention, the arc of the rod body of the elastic member 130 is 8 ° to 90 °.

In some embodiments of the invention, the shaft is covered by a thin outer cover. The material of the thin layer outer sleeve can be plastic or stainless steel. The thin layer coat protects the rod body or decorates the rod body, so that the rod body is attractive in appearance, or the bending strength of the rod body is enhanced, and the cost is reduced.

In some embodiments of the present invention, the material of the flexible carrier 121 may be any flexible material such as cloth, fiber, nylon, etc.

Preferably, in some embodiments of the present invention, referring to fig. 3, the adaptive unit 120 further includes a support 140, and the support 140 supports the elastic member 130 to be movable up and down; the supporting member is disposed below, at two ends or above the elastic member 130. The structure of the supporting member 140 is flexible and changeable, and may be changed according to the structure of the elastic member 130 and its purpose, and is configured as an inelastic supporting member or an elastic supporting member. The non-elastic supporting member can be structurally arranged to be a holding groove or a holding hole matched with the shape and the extending direction of the rod body of the elastic member 130, the rod body penetrates through the holding groove or the holding hole, the holding groove or the holding hole is in the same direction as the extending direction of the rod body, and has a certain limiting effect, namely, sufficient deformation space is provided for the rod body, and the rod body is blocked in the deformation process in front and back directions of the rod body and can only deform in the left direction, the right direction and the up and down directions.

When the supporting member 140 is an elastic supporting member, the elastic member 130 is elastically supported to move up and down. That is, when the elastic member 130 moves downward, the elastic support member 140 is pressed downward, so that the elastic support member 140 is deformed to provide a downward movement space for the elastic member 130. When the pressure on the flexible carrier is removed, the elastic support 140 is reset, and the elastic member 130 is pushed to reset. The supporting elastic member 140 enables the elastic member 130 to move up and down, so that the adaptive unit 120 can move up and down according to the borne weight, and has a good buffering effect and a better adaptive effect, so that a person feels more comfortable. The elastic support 140 is preferably a circular wire spring or a spring plate.

Preferably, the supporting member 140 is mounted on the fixing base 110 b. Of course, the supporting member 140 can be mounted on other structures, such as the mounting member 133, according to the specific structure of the product.

Preferably, in some embodiments of the present invention, the fixing base 110 includes a plurality of limiting members 180, and the limiting members 180 are connected to the elastic member 130 in a one-to-one correspondence manner to limit that the elastic member 130 can only move up and down and cannot swing left, right, front, and back. Specifically, the elastic member 130 is provided with a mounting seat 142. The limiting member 180 may be a straight rod with elasticity as shown in fig. 14, and passes through an installation base 142, and two ends of the limiting member are fixed on the fixing base 110. The elastic member 130 and the limiting member 80 are fixedly connected through the mounting seat 142. When the elastic member 130 is pulled by the flexible carrier 121 to deform, the elastic member 130 presses the limiting member 180 through the mounting base 142, and two ends of the limiting member 180 are fixed and can only move up and down and cannot swing back and forth and left and right, so that the moving direction of the elastic member 130 is also limited. Preferably, the limiting member 180 is two straight rods with elasticity arranged in parallel. It should be understood that the limiting member 180 may be provided in other structures that can satisfy the requirement of "limiting the movement direction of the elastic member 130 to only move up and down".

It should be understood that the fixing base is used for integrating the adaptive unit, and the structure of the fixing base can be flexibly changed according to the shape of the rod body of the adaptive unit, the installation requirement and the product. For example, in some embodiments of the present invention, the cushion support structure 100 is used for a product that is convenient to take, such as a throw pillow or a back cushion, the fixing seat 110a may be a two-side connecting straight rod, as shown in fig. 1 and 2, the two-side connecting straight rod is provided with a plurality of slots corresponding to the rod ends 131 one by one; the rod end 131 passes through the slot and is constrained to move within the slot. The slot is preferably oblong. The slot is larger than the outer diameter of rod end 131 such that rod end 131 can pass through the slot within which the rod body can move. The slotted hole also limits the moving range of the rod body, so that the rod body is prevented from being bent or broken due to transition deformation under the action of pressure.

For example, in some embodiments of the present invention, the cushion support structure 100 is used for a sofa cushion, a car seat, a pillow, a mattress, etc. to be fixed on a product, the fixing base 110b may be configured to have a base and a bottom frame, etc., and the support member, the mounting base, the mounting member, etc. are fixed on the fixing base 110 b. As shown in fig. 3 and 13.

Referring to fig. 14 and 15, a cushion support structure includes a holder 110c, a plurality of elastic members 130 and at least one flexible carrier 121; the elastic members 130 are arranged on the fixed seat 110c side by side, each elastic member 130 has two symmetrical rod ends 131, and the two rod ends 131 are respectively and fixedly connected to the fixed seat 110c; two opposite side edges of the flexible carrier 121 are respectively and fixedly connected to the fixing seat 110c, so that the flexible carrier 121 is erected above the elastic member 130; the flexible carrier 121 is deformed by pressure, and pulls the fixing base 110c connected with the flexible carrier to relatively fold, so that the elastic member 130 is deformed; when the pressure is removed, the elastic member 130 is reset, and the flexible carrier 121 is tensioned again.

Each elastic member 130 has a rod 132 connected to the rod end 131, and the position near the connection between the rod end 131 and the fixed base 110 is an obtuse angle, so as to prevent the rod 132 from being contacted when the positions near two opposite sides of the flexible carrier 121 are pressed down.
