Description

Technical Field

[0001] This utility model relates to a massage backrest. Background Technology

[0002] In existing technologies, the design of massage backrests often focuses on the realization of massage functions while neglecting the comfort of the user experience. Massage backrests on the market cannot be lightweight, making them inconvenient to carry and use; their structures are relatively rigid, often failing to fit the body shape of each individual. During the massage, they cannot perfectly match the user's sitting posture, requiring the user to adjust to the position of the mechanism. This is because traditional backrest support structures often use straight or simple curved designs, making it difficult to fully conform to the natural curve of the user's back, especially during prolonged use, which can easily cause discomfort to the back muscles and bones. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a massage backrest for massaging the human body.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] It includes a back frame, a movement, and a rack, wherein the rack is fixed inside the back frame, and the movement moves up and down along the back frame under the guidance of the rack.

[0006] It also includes an outer cover and support bars, the support bars being made of elastic material, the support bars being at least two sets, and the two ends of each set of support bars being connected to one side of the back frame, the movement being disposed between the two sets of support bars, the support bars being curved and protruding towards the user, the height of the protruding support bars being higher than the height of the movement;

[0007] The outer cover covers the support bar, the back frame, and the movement. When in use, the support bar and the outer cover elastically abut against the user to create a cushion between the user and the movement.

[0008] The technical solution provided by this utility model has the following beneficial effects:

[0009] By designing support strips, the massage backrest becomes thinner and lighter, making it more portable. The support strips are elastic, creating a cushion between the user and the massage mechanism, effectively distributing pressure and reducing fatigue during prolonged use. The curved design and protruding shape of the support strips, together with the cover, can automatically adjust according to the user's different widths, pressures, and fitting angles. This allows the massage backrest to better conform to the body's contours at any angle and massage posture, resulting in a better massage effect and greater ergonomics. Attached Figure Description

Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0016] In the description of this invention, terms such as "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0018] Reference Figures 1 to 5 As shown, this embodiment provides a massage backrest for massaging the human body, including a backrest frame 3, a mechanism 1 and a rack 2. The rack 2 is fixed inside the backrest frame 3, and the mechanism 1 moves up and down along the backrest frame 3 under the guidance of the rack 2.

[0019] It also includes an outer cover (not shown in the figure) and support bars 4. The support bars 4 are made of elastic material. There are at least two sets of support bars 4, and the two ends of each set of support bars 4 are connected to one side of the back frame 3. The movement 1 is disposed between the two sets of support bars 4. The support bars 4 are curved and protrude towards the user. The height of the protrusion of the support bars 4 is higher than the height of the movement 1.

[0020] The outer cover covers the support bar 4, the back frame 3 and the movement 1. When in use, the support bar 4 and the outer cover elastically abut against the user to create a buffer between the user and the movement 1.

[0021] By designing support strips, the massage backrest becomes thinner and lighter, making it more portable. The support strips are elastic, creating a cushion between the user and the massage mechanism, effectively distributing pressure and reducing fatigue during prolonged use. The curved design and protruding shape of the support strips, together with the cover, can automatically adjust according to the user's different widths, pressures, and fitting angles. This allows the massage backrest to better conform to the body's contours at any angle and massage posture, resulting in a better massage effect and greater ergonomics.

[0022] Furthermore, it also includes a cloth strip (not shown in the figure) and cloth strip covers 5. The mechanism 1 also has limiting holes 6 for the cloth strip to pass through. At least two cloth strip covers 5 are provided on the upper and lower sides of the backrest frame 3 and fix the cloth strip in the middle of the backrest frame 3. When the mechanism 1 moves up and down along the rack 2, it also moves up and down along the cloth strip. The cloth strip makes the up and down movement of the mechanism 1 more stable, and when the user touches the massage backrest, the parts of the human body other than the part that touches the mechanism 1 can contact the flexible cloth strip, avoiding direct contact with the backrest frame 3, thus playing a supporting and cushioning role.

[0023] Furthermore, the backrest frame 3 has curved base plate portions 31 extending towards the user at both its upper and lower ends, and the support strip 4 is connected to the curved base plate portions 31. The support strip 4, which has a certain degree of elasticity, and the curved base plate portions 31 extending towards the user, not only ensure the structural strength of the massage backrest, but also transmit the user's pressure to the backrest frame 3, allowing the massage backrest to bend and deform at a certain angle, thus making it more suitable for different pressure usage scenarios.

[0024] Furthermore, a connecting strip 311 is provided at the top of the curved portion 31 of the base plate. The connecting strip 311 is connected to the support strip 4 and abuts against the user. The two connecting strips 311 at the top and bottom and the two support strips 4 at the left and right form a "U" shape to strengthen the structural strength of the support strip 4, and together they abut against the user to conform to the user's body.

[0025] Furthermore, the support bar 4 protrudes towards the user while also protruding outwards towards the back frame 3, in order to increase the contact area between the support bar 4 and the cover and the user, so as to adapt to different user body shapes.

[0026] Furthermore, a roller 11 is provided at the bottom of the movement 1. The roller 11 moves up and down on the side of the back frame 3 closest to the user. The roller 11 can share the pressure of the user and reduce the friction when the movement 1 moves up and down on the back frame 3.

[0027] Furthermore, the backrest frame 3 is provided with a bottom plate reinforcing rib 31 on the side away from the user. Preferably, the bottom plate reinforcing rib 31 is located on the side of the backrest frame 3 away from the user, which ensures the structural strength of the backrest frame 3, does not affect the up and down movement of the roller 11, and avoids the bottom plate reinforcing rib 31 from contacting the user and causing a foreign object sensation.

[0028] Furthermore, it also includes a PCB board 7, which controls the operation of the massage backrest.

[0029] Furthermore, it also includes a manual control box (not shown in the figure). The manual control box is connected to the PCB board 7 via a wire passing through the gap between the support bar 4 and the backrest frame 3, or the manual control box can be wirelessly connected to the PCB board 7. The manual control box is located below the support bar 4 or in another position where it does not come into contact with the user during massage. Due to the supporting effect of the support bar 4, the user will not put pressure on the manual control box when pressing or squeezing the massage backrest, thus avoiding accidental activation of the manual control box.

[0030] Furthermore, the support strip 4 is made of polypropylene. Of course, in other embodiments, the material of the support strip is not limited to this, such as engineering plastics.

[0031] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
