Technical Field

[0001] This utility model relates to the field of massage instrument technology, and in particular to a flexible massage backrest and massage sofa that conforms to the human back. Background Technology

[0002] Existing flexible massage backrest rack frames on the market, such as the suspended massage cushion disclosed in Chinese patent application number CN202421703757.2, include a walking massage mechanism and a pair of rack rails. The walking massage mechanism is clamped on the rack rails on both sides, and the rack rails provide support for the walking massage mechanism. The pair of rack rails are set on a middle plate, and a support frame is set outside the middle plate. At least one end of the middle plate is connected to the support frame through an elastic structure.

[0003] Currently, the middle plate and rack in the flexible massage backrest rack frame are in a flat state when not under load. When under massage load, the rack will adaptively bend to varying degrees according to the amount of force applied. When not under massage load, it returns to a flat state.

[0004] However, the middle plate and toothed rack cannot protrude in areas that require raised massage, such as the waist, or create depressions in areas that require recessed massage, such as the shoulder blades, to adapt to the curves of the human back. As a result, when the massage mechanism moves to the corresponding positions on the back, waist, or shoulder blades, it cannot conform to the curves of the back, affecting comfort. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a flexible massage backrest and massage sofa that conforms to the human back, which can make the middle plate and toothed strips deform in advance to adapt to the curve of the human back and improve comfort.

When the protruding structural member is fixed in a position corresponding to the waist, the protrusion faces the direction of the human waist, and the protrusion causes the middle plate and the rack to be lifted at the waist position to conform to the waist curve. When the protruding structure is fixed in a position corresponding to the scapula or head, the protrusion faces away from the back of the human body, and the protrusion causes the middle plate and rack to be recessed at the scapula or head position to conform to the curve of the scapula or head.

[0007] Furthermore, it also includes an outer frame, with the middle plate connected to the inside of the outer frame via elastic connectors.

[0008] Furthermore, the elastic connector includes a first connector with corrugated pleats, which is respectively disposed at the upper and lower ends of the middle plate.

[0009] Furthermore, the elastic connector also includes several corrugated second connectors, which are located at the corners of the middle plate.

[0010] Furthermore, the outer frame includes several border units, and a deformable third connector is integrally formed between adjacent border units.

[0011] Furthermore, the middle plate is also provided with a guide groove, and the massage mechanism is provided with a guide block, which is slidably connected in the guide groove.

[0012] Furthermore, a fixing block is provided on the side of the outer frame away from the back of the human body, and the two ends of the protruding structural member are respectively connected to the fixing block.

[0013] Secondly, this utility model also provides a massage sofa that conforms to the waist of the human body, including a flexible massage backrest that conforms to the back of the human body as described in the first aspect.

[0027] Example 1, please refer to Figures 1 to 4 This utility model provides a flexible massage backrest that conforms to the human back, including a middle plate 1 made of flexible material. The middle plate 1 is connected to a toothed rack 2, which is integrally formed on the side of the middle plate 1. The massage backrest also includes a protruding structural member 3 that causes the middle plate 1 to bend. The protruding structural member fixes the middle plate away from the human back. The protruding structural member 3 is fixed at a position corresponding to the waist, shoulder blade, or head. Both ends of the protruding structural member 3 are fixed to the outside of the middle plate 1. The middle part of the protruding structural member 3 has a protrusion 31, which is located between two toothed racks 2 arranged left and right. The protrusion 31 is connected to the middle plate, causing the middle plate to bend flexibly.

[0028] When the protruding structural member 3 is fixed at a position corresponding to the waist, the protrusion 31 faces the waist of the human body and abuts against the middle plate. The protrusion 31 causes the middle plate 1 and the rack 2 to be lifted at the waist position to conform to the waist curve.

[0029] When the protruding structural member 3 is fixed in a position corresponding to the scapula or head, the protrusion 31 faces away from the back of the human body. The protrusion 3 causes the middle plate 1 and the rack 2 to be recessed at the scapula or head position to conform to the curve of the scapula or head. The protrusion 31 faces away from the back of the human body, and the middle plate is connected to the protrusion 31 by screws or straps to pull the position on the middle plate corresponding to the scapula or head of the human body to the side away from the back of the human body, so that the middle plate is recessed at the scapula or head position.

[0030] Specifically, it also includes an outer frame 4, and the middle plate 1 is connected to the inner side of the outer frame 4 by an elastic connector. The outer frame 4 is also made of a flexible material, and the outer frame 4, the elastic connector, and the middle plate 1 are integrally formed.

[0031] Specifically, the elastic connector includes a first connector 5 with corrugated pleats, which is respectively disposed at the upper and lower ends of the middle plate 1. The elastic connector allows the middle plate 1, which carries the massage mechanism 6, to float up and down relative to the outer frame 4, adapting to changes in the human body's curves and maintaining a relatively constant massage force.

[0032] Specifically, the middle plate 1 is also provided with a guide groove 101, and the massage mechanism 6 is provided with a guide block, which is slidably connected in the guide groove 101. When the massage mechanism 6 moves, the guide groove 101 and the guide block cooperate to guide the movement of the massage mechanism 6.

[0033] Specifically, the outer frame 4 has a fixing block 41 on the side away from the back of the human body, and the two ends of the protruding structural member 3 are respectively connected to the fixing block 41.

[0034] Example 2, please refer to Figures 5 to 8 This utility model also provides a flexible massage backrest that conforms to the human back, including a middle plate 1 made of flexible material. The middle plate 1 is connected to a toothed rack 2, which is integrally formed on the side of the middle plate 1. The massage backrest also includes a protruding structural member 3 that causes the middle plate to flexibly bend. The protruding structural member 3 is fixed at a position corresponding to the waist, shoulder blade, or head. Both ends of the protruding structural member 3 are fixed to the outside of the middle plate 1. The middle part of the protruding structural member 3 has a protrusion 31, which is located between two toothed racks 2 arranged left and right. The protrusion 31 is connected to the middle plate, causing the middle plate to flexibly bend.

[0035] When the protruding structural member 3 is fixed at a position corresponding to the waist, the protrusion 31 faces the waist of the human body and abuts against the middle plate. The protrusion 31 causes the middle plate 1 and the rack 2 to be lifted at the waist position to conform to the waist curve.

[0036] When the protruding structural member 3 is fixed in a position corresponding to the scapula or head, the protrusion 31 faces away from the back of the human body. The protrusion 3 causes the middle plate 1 and the rack 2 to be recessed at the scapula or head position to conform to the curve of the scapula or head. The protrusion 31 faces away from the back of the human body, and the middle plate is connected to the protrusion 31 by screws or straps to pull the position on the middle plate corresponding to the scapula or head of the human body to the side away from the back of the human body, so that the middle plate is recessed at the scapula or head position.

[0037] Specifically, it also includes an outer frame 4, and the middle plate 1 is connected to the inner side of the outer frame 4 by an elastic connector. The outer frame 4 is also made of a flexible material, and the outer frame 4, the elastic connector, and the middle plate 1 are integrally formed.

[0038] Specifically, the elastic connector includes a first connector 5 with corrugated pleats, which is respectively disposed at the upper and lower ends of the middle plate 1. In this embodiment, there are four first connectors 5, which are divided into two groups and disposed at the upper and lower ends of the middle plate 1 respectively.

[0039] Specifically, the elastic connector further includes several corrugated second connectors 7, which are located at the corners of the middle plate 1. There are four second connectors 7, which are also divided into two groups, respectively located on the left and right sides of the middle plate 1. The two second connectors 7 in the same group are located near the upper and lower ends of the side of the middle plate 1, respectively.

[0040] like Figure 8 As shown, the first connecting member 5 extends along the Y-axis direction of the middle plate 1 (i.e., the upper and lower ends of the middle plate 1), and the second connecting member 7 is arranged along the X-axis direction of the middle plate 1 (i.e., the left and right sides of the middle plate 1), allowing the middle plate 1 to deform freely in both the X and Y directions. During use, this allows the middle plate 1 to float up and down relative to the outer frame 4, maintaining a relatively constant massage force. Under heavy pressure, the elastic connecting member will deform downwards, reducing the massage force; under light load, the elastic connecting member will return to its initial position.

[0041] Specifically, the outer frame 4 includes several border units, and a deformable third connector 8 is integrally formed between adjacent border units. Figure 8 As shown, the outer frame 4 is composed of a left side frame unit 42, a middle side frame unit 43, and a right side frame unit 44; the two ends of the middle side frame unit 43 are integrally formed with the left side frame unit 42 and the middle side frame unit 43 through a third connector 8, respectively; of course, those skilled in the art can divide the outer frame 4 into more frame units according to the technical solution of this utility model, and adjacent frame units can be integrally formed through an elastic third connector 8, which should also be covered within the scope of protection of the claims of this utility model.

[0042] like Figure 8 As shown, the left and right side frame units and the middle frame unit 43 are integrally formed by the elastic third connector 8, which allows the outer frame 4 to adapt to different massage sofa frames, making it easy to match with various massage sofa structures and broadening the product's applicability.

[0043] The third connector 8 is straight, and its thickness is less than that of the outer frame 4. In addition to enabling the outer frame 4 to adapt to different massage sofa frames, the third connector 8 can also be freely bent and deformed, so that the left side frame unit 42, the middle side frame unit 43, and the right side frame unit 44 can be assembled at a certain angle as required.

[0044] Of course, the third connector 8 can also be the same as the first connector 5 or the second connector 7, all of which adopt a corrugated pleated structure, so that the third connector 8 is elastic and can be deformed.

[0045] like Figure 8 As shown, the middle frame unit 42 is connected to the middle plate 1 via the first connector 5. The left frame unit 43 is connected to the middle plate 1 via a set of second connectors 7, and the right frame unit 44 is connected to the middle plate 1 via another set of second connectors 7.

[0046] Specifically, the middle plate 1 is also provided with a guide groove 101, and the massage mechanism 6 is provided with a guide block, which is slidably connected in the guide groove 101. When the massage mechanism 6 moves, the guide groove 101 and the guide block cooperate to guide the movement of the massage mechanism 6.

[0047] Example 3, please refer to Figures 5 to 8 This utility model also provides a massage sofa that conforms to the human waist, including a flexible massage backrest that conforms to the human back as described in Embodiment 2, and a support 9 made of a rigid material. The end of the protruding structural member 3 is fixedly connected to the support 9. In this embodiment, the rigid material refers to materials such as metal, wood, or plastic.

[0048] Specifically, the support 9 consists of a backrest support 91 and a seat cushion support 92. The flexible massage backrest is connected to the backrest support 91, and the seat cushion support 92 is connected to the seat cushion 10. The backrest support 91 and the seat cushion 10 are connected by a hinge 11 that can be adjusted to multiple positions. The hinge 11 with multiple positions is also called a joint hinge 11, commonly used in the backrest structure of sofas and recliners, and is existing technology; therefore, it will not be described in detail here. In this embodiment, the multiple positions of adjustment mean that the backrest support 91 can unfold relative to the surface of the seat cushion support 92 from 90° to 180°, forming multiple angles with the seat cushion support 92 to adapt to different user needs. Furthermore, it can be folded down to near 0° for storage when not in use, saving storage space. The seat cushion 10 also has a groove to avoid the backrest support 91 from pressing against the seat cushion 10 when the backrest support 91 and the seat cushion support 92 are folded.

[0049] Specifically, the seat cushion 10 is made of sponge or plastic. The upper surface of the seat cushion 10 conforms to the curve of the human buttocks. In this embodiment, the flexible massage backrest is screwed onto the backrest support 91, and the seat cushion 10 is screwed onto the seat cushion support 92. Of course, the massage sofa in this embodiment also includes a flexible cover (sofa cover) that covers the backrest support 91 and the seat cushion support 92, enclosing the seat cushion 10 and the flexible massage backrest. The flexible cover is made of leather or cloth.

[0050] The advantages of this invention are: by adding protruding structural components to the waist, shoulder blade or head position of the flexible massage backrest, the original flat middle plate and toothed rack are made to have a certain curvature to adapt to the curve of the human back, so that the massage mechanism can move to the corresponding position and fit the back for massage, thus improving the massage comfort.

[0051] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
