[0029] Reference below Figures 1-8 A waist support structure 100 according to an embodiment of the first aspect of the present invention is described.

[0030] like Figures 1-8 As shown, the lumbar support structure 100 according to the embodiment of the first aspect of the present invention includes: a lumbar support component 1 and an adjustment component 2.

[0031] Specifically, the lumbar support assembly 1 is arranged in the backrest of the seat, and the lumbar support assembly 1 includes: a support member 11 and a sliding seat 12, and the support member 11 is movably connected to the sliding seat 12. Figure 1 and Figure 2 As shown, the support member 11 extends vertically along an arc that bulges away from the sliding seat 12. The adjustment assembly 2 is connected to the support member 11 and is used to adjust the relative position of the support member 11 and the sliding seat 12. It can be understood that when the user squeezes the lumbar support structure 100, the support member 11 adaptively adjusts its front-to-back position based on the user's posture. The relative position of the support member 11 and the sliding seat 12 is adjusted by the adjustment assembly 2, thereby achieving adjustable position of the lumbar support assembly 1.

[0032] According to the lumbar support structure 100 of the embodiment of the present invention, an adjustment component 2 is provided, and the relative position between the support member 11 and the sliding seat 12 is changed by the adjustment component 2, thereby adjusting the height of the lumbar support, ensuring that the lumbar support can accurately support the user's waist to adapt to different sitting postures, meet the user's personalized needs, and improve the overall hardness and health and comfort.

[0033] In some embodiments of the present invention, the adjustment assembly 2 includes: an adjustment member, both ends of which are connected to the support member 11; a control member, which includes a fixed seat 22 and a knob 23. A sliding channel extending in the vertical direction is formed in the fixed seat 22, and at least part of the adjustment member is located in the sliding channel. The adjustment member can slide in the vertical direction relative to the fixed seat 22, and the knob 23 is rotatably connected to the fixed seat 22. The relative position of the adjustment member and the fixed seat 22 can be adjusted by rotating the knob 23. Figure 1-Figure 5 As shown, the user adjusts the height of the support member 11 by rotating the knob 23, and the rotation of the knob 23 is converted into the up and down movement of the adjustment member in the sliding channel. As a result, the difficulty of adjustment for the user is reduced, the adjustment accuracy is improved, and the service life is extended.

[0034] Furthermore, the fixing seat 22 includes two engaging parts that cooperate with each other, and the sliding channel is defined by the cooperation of the two engaging parts.

[0035] In some embodiments of the present invention, the knob 23 includes a rotating shaft 24, and the fixed seat 22 includes a latching member, the latching member is formed with a first meshing tooth, and one end of the rotating shaft 24 is formed with a second meshing tooth. The rotating shaft 24 and the latching member are meshedly connected via the first meshing tooth and the second meshing tooth. The adjusting member is connected to the latching member, and the rotating shaft 24 rotates to drive the latching member to move within the sliding channel. Specifically, the knob 23 includes a housing and a spring, the spring is provided in the latching member, the housing is connected to the rotating shaft 24, and the rotating shaft 24 is meshedly connected to the latching member. The rotating shaft 24 rotates to drive the latching member to move, and the latching member drives the pull wire 21 to move, thereby adjusting the relative position of the support member 11 and the fixed seat 22. As a result, the structure of the adjustment assembly 2 is simple and reliable, easy to assemble, not prone to failure, and has high adjustment accuracy, which can meet the needs of different users.

[0036] Furthermore, the adjustment assembly 2 also includes a locking member. When adjusted to a suitable position, the locking member is used to keep the tooth member in the current position, thereby ensuring the stability and reliability of the adjustment assembly 2.

[0037] In order to ensure the aesthetics of the adjustment assembly 2, the knob 23 further includes a cover and a decorative ring. The cover is provided on the side of the housing away from the fixing seat 22, and the decorative ring is provided on the housing. Preferably, the cover and the decorative ring are both resin parts, and the housing is a plastic part.

[0038] Reference Figure 4 As shown, a plurality of connection holes are formed on the side of the fixing seat 22 away from the knob 23 for passing fasteners therethrough to fix the fixing seat 22 to the backrest of the seat.

[0039] In some embodiments of the present invention, a first sliding hole 121 extending in the vertical direction is formed on the sliding seat 12. The first sliding hole 121 penetrates the sliding seat 12 in the thickness direction of the sliding seat 12. The lumbar support assembly 1 also includes a first connecting member 13, which is connected to the support member 11 via a fastener, and the fastener is disposed in the first sliding hole 121. As a result, the first sliding hole 121 limits the sliding distance and sliding direction of the support member 11, making the lumbar support structure 100 more stable and reliable, and improving the user experience.

[0040] Preferably, the support member 11 is pre-embedded with a nut 111 for threaded connection with a fastener; the sliding seat 12 is a plastic member, and the support member 11 is also a plastic member.

[0041] Further, if Figure 8As shown, the first sliding holes 121 include a plurality of them, spaced apart horizontally. The sliding seat 12 includes a second sliding hole 122 extending in the vertical direction. The second sliding hole 122 penetrates the sliding seat 12 in the thickness direction of the sliding seat 12. The second sliding hole 122 and the first sliding hole 121 are spaced apart in the vertical direction. The lumbar support assembly 1 also includes a second connecting member 14, which passes through the second sliding hole 122 and the support member 11. Thus, the plurality of first sliding holes 121 ensures synchronization during the movement of the support member 11, and the provision of the second sliding hole 122 further enhances the stability of the support member 11 during movement, reducing the failure rate of the lumbar support assembly 1 and extending the service life of the lumbar support assembly 1.

[0042] In some embodiments of the present invention, the lumbar support assembly 1 further includes: a sliding body 15, which is connected to the sliding seat 12; and a sliding base 17, which is detachably connected to the sliding body 15. This simplifies the assembly steps of the lumbar support assembly 1, reduces the difficulty of disassembly and assembly of the lumbar support assembly 1, and facilitates maintenance or replacement of parts.

[0043] Furthermore, a clamping member 16 is connected between the sliding base 17 and the sliding body 15, and a connecting channel is formed in the clamping member 16. The sliding body 15 is formed with a first connecting tube 151, and the first connecting tube 151 is located in the connecting channel. A first clamping protrusion is formed on the inner peripheral wall of the clamping member 16, and a first clamping groove is formed on the outer peripheral wall of the first connecting tube 151, and the first clamping protrusion extends into the first clamping groove. A second connecting tube 171 is formed on the sliding base 17, and the clamping member 16 is sleeved in the second connecting tube 171. A second clamping protrusion 161 is formed on the outer peripheral wall of the clamping member 16, and a second clamping groove is formed on the second connecting tube 171, and the second clamping protrusion 161 extends into the second clamping groove. Specifically, when the first connecting tube 151 is inserted into the connecting channel of the clamping member 16, the first latching protrusion on the clamping member 16 extends into the first latching groove on the first connecting tube 151, forming a snap fit. When the clamping member 16 is sleeved onto the second connecting tube 171, the second latching protrusion 161 on the clamping member 16 extends into the second latching groove on the second connecting tube 171, forming a snap fit. Thus, the connection between the sliding body 15 and the sliding base 17 is simple and reliable, and the clamping member 16 is cleverly designed, facilitating assembly and disassembly.

[0044] Furthermore, a first mounting protrusion is formed on the sliding base 17, and a second mounting protrusion is formed on the sliding body 15. An elastic member is connected between the first mounting protrusion and the second mounting protrusion, and the elastic member is located within the clamping member 16. Therefore, the provision of the elastic member between the sliding base 17 and the sliding body 15 improves the user experience and ensures the comfort of the lumbar support assembly 1.

[0045] Preferably, the sliding base 17 is a plastic part, the clamping part 16 is a polyoxymethylene part, and the sliding body 15 is a plastic part.

[0046] In some embodiments of the present invention, a first fixing groove is formed on the first connecting member 13, and the two ends of the adjusting member are arranged in the first fixing groove. The adjusting member includes a pull wire 21 and a bushing. The bushing is arranged in the second fixing groove of the sliding seat 12, and the pull wire 21 is sleeved in the bushing and is movable relative to the bushing. It is understandable that the two ends of the pull wire 21 are fixed in the first fixing groove of the first connecting member 13, the bushing is fixed in the second fixing groove, and the pull wire 21 is sleeved in the bushing. As a result, the friction between the pull wire 21 and the lumbar support assembly 1 is reduced, allowing the pull wire 21 to move smoothly.

[0047] In some embodiments, a fixing plate 3 is also included. The fixing plate 3 is arranged in the shaping cotton. Since direct contact and friction between the plastic part and the shaping cotton may cause jamming or stiffness during movement, the fixing plate 3 is formed as a polyformaldehyde part, which plays a lubricating role between the plastic part and the fixing plate 3.

[0048] When the user squeezes the lumbar support assembly 1, the lumbar support assembly 1 will adaptively adjust its front and rear position. By rotating the knob 23, the pull wire 21 can be adjusted up and down. Since the pull wire 21 is connected to the first connecting member 13, the pull wire 21 moves up and down, driving the support member 11 to move up and down, thereby realizing the up and down adjustment of the lumbar support assembly 1.

[0049] The seat according to the second embodiment of the present invention includes the lumbar support structure 100 according to the first embodiment of the present invention.

[0050] The seat according to the embodiment of the present invention is provided with the lumbar support structure 100 of the first embodiment, thereby improving the comfort of the seat and providing sufficient support for the user's waist.
