Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] As described in the background section, existing fishing chairs generally use a lumbar support structure to support the user's lower back. However, lumbar supports are usually fixed and passively supportive, which has problems such as insufficient support performance and lack of flexibility. They are difficult to effectively relieve the pressure on the lower back caused by prolonged sitting, resulting in poor comfort and reduced user experience.

[0029] Based on this, please refer to Figures 1-8 The present invention provides a lumbar support component 100 and a fishing chair 1000, which can effectively improve the technical problems mentioned above. That is, it has good support, strong support, flexibility and comfort, and can effectively relieve the pressure on the lower back caused by prolonged sitting, thereby improving the user's comfort and experience.

[0030] It should be noted that the first direction mentioned below refers to... Figures 1-8The Z direction is shown in the figure, and the second direction is... Figures 1-8 The Y direction shown in the figure, the third direction is Figures 1-8 The X direction is shown in the figure. The lumbar support assembly 100 and the fishing chair 1000 will be described in detail below.

[0031] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the fishing chair 1000 provided in this embodiment in its unfolded state. Figure 2 This is a schematic diagram showing the fishing chair 1000 provided in this embodiment in a folded state. (In conjunction with...) Figure 1 and Figure 2 The fishing chair 1000 includes a lumbar support component 100, a folding chair frame 200, and a backrest soft surface 300. The backrest soft surface 300 is disposed on the folding chair frame 200, and the lumbar support component 100 is disposed on the backrest soft surface 300. The lumbar support component 100 is used to provide support for the user's lower back.

[0032] For details, please refer to Figure 3 and Figure 4 , Figure 3 This is a structural schematic diagram of the lumbar support assembly 100 provided in this embodiment. Figure 4 This is an exploded view of the lumbar support assembly 100 provided in this embodiment. (In conjunction with...) Figure 3 and Figure 4 The lumbar support assembly 100 includes a mounting fastener 10, an elastic torsion structure 20, and at least two lumbar supports 30. The at least two lumbar supports 30 are spaced apart from the mounting fastener 10, and each lumbar support 30 is connected to the mounting fastener 10 via the elastic torsion structure 20. Under the action of an external force, the lumbar support 30 drives the elastic torsion structure 20 to twist, thereby swinging relative to the mounting fastener 10. Furthermore, when the external force is removed, the elastic torsion structure 20 drives the lumbar support 30 to swing, so that the lumbar support 30 returns to its initial state.

[0033] As is easily understood, during use, the user's lower back rests against the lumbar support 30. When the lower back twists, the lumbar support 30 applies force to the elastic torsional structure 20, allowing the lumbar support 30 to move with the lower back. Furthermore, the torsional force of the elastic torsional structure 20 ensures the lumbar support 30 remains firmly against the lower back, improving support and providing cushioning elasticity for enhanced support performance. Simultaneously, by incorporating at least two lumbar support structures 30, it can better conform to different positions of the lower back, offering good wrapping, flexibility, and comfort, effectively relieving pressure on the lower back caused by prolonged sitting and improving user comfort and experience.

[0034] It should be noted that in this embodiment, the number of lumbar supports 30 is specifically two; of course, in other embodiments, the number of lumbar supports 30 can also be three or four, etc. Furthermore, specifically in this embodiment, the mounting fastener 10 is a mounting plate; of course, in other embodiments, the mounting fastener 10 can also be a fixing pipe or other mounting and fixing structure.

[0035] Please combine them together Figures 1-4 Specifically, in this embodiment, the mounting fastener 10 is detachably mounted on the soft backrest surface 300. It should be noted that the folding chair frame 200 has a folding function, combined with... Figure 2 When the folding chair frame 200 is folded, the lumbar support component 100 will be stored inside the folding chair frame 200. That is, the overall volume of the fishing chair 1000 after being folded remains unchanged, without affecting the normal packaging volume, which can save space and reduce packaging and transportation costs.

[0036] To facilitate the disassembly and installation of the lumbar support assembly 100 and improve the efficiency of disassembly and installation, a first insertion port and a second insertion port (not shown in the figure) are respectively opened on the opposite sides of the backrest soft surface 300, and the two ends of the mounting fastener 10 are respectively inserted into the first insertion port and the second insertion port.

[0037] Furthermore, the lumbar support assembly 100 also includes a first hook and loop fastener 41 and a second hook and loop fastener 42, which are spaced apart from each other on the mounting fastener 10. A third hook and loop fastener (not shown) are respectively provided in the first and second insertion ports. The first hook and loop fastener 41 is used to adhere to the third hook and loop fastener, and the second hook and loop fastener 42 is used to adhere to the fourth hook and loop fastener. In other words, after the two ends of the mounting fastener 10 are inserted into the first and second insertion ports respectively, by attaching the first hook and loop fastener 41 to the third hook and the second hook and loop fastener 42 to the fourth hook and loop fastener, the stability of the lumbar support assembly 100 installed on the backrest soft surface 300 can be improved.

[0038] It should be noted that, specifically in this embodiment, the first Velcro 41 and the second Velcro 42 are respectively disposed at both ends of the mounting fastener 10; of course, in other embodiments, the first Velcro 41 and the second Velcro 42 can also be disposed at other positions of the mounting fastener 10, as long as they can achieve adhesive bonding.

[0039] In addition, the first and second sockets are respectively provided with a first cover and a second cover. When the lumbar support is removed and Velcro fastening is not required, the first cover and the second cover can cover the first and second sockets respectively, which can prevent damage to the Velcro and make the fishing chair look better overall.

[0040] Please refer to Figure 5 , Figure 5This is an exploded view of the lumbar support 30 and the elastic torsion structure 20 provided in this embodiment, combined with... Figure 4 and Figure 5 The elastic torsion structure 20 includes a fixed base 21, a pressure cover 22, and an elastic torsion member 23. The fixed base 21 is disposed on the side of the lumbar support 30 near the mounting fastener 10, and the pressure cover 22 is disposed on the side of the mounting fastener 10 near the lumbar support 30, with the pressure cover 22 and the fixed base 21 spaced apart; the elastic torsion member 23 is connected to both the fixed base 21 and the pressure cover 22.

[0041] As is easily understood, when an external force is applied to the lumbar support 30, it is transmitted to the elastic torsion member 23 through the fixed seat 21, causing the elastic torsion member 23 to twist. Simultaneously, the fixed seat 21 moves relative to the pressure cover 22, thereby causing the lumbar support 30 to move with the user's back. During this process, the torque of the elastic torsion member 23 acts on the lumbar support 30, ensuring it fits snugly against the back, thus providing stable support. Of course, when the external force is removed, i.e., when the back moves away from the lumbar support 30, the elastic torsion member 23 will cause the lumbar support 30 to return to its initial stationary state. Furthermore, by cooperating with the elastic torsion member 23, the stability of the lumbar support 30 during movement can be improved.

[0042] For details, please refer to Figure 6 , Figure 6 This is a schematic diagram of the elastic torsion structure 20 provided in this embodiment, combined with... Figures 4-6 The elastic torsion member 23 includes a first connecting portion 231, a first spiral portion 232, a snap-fit ​​portion 233, a second spiral portion 234, and a second connecting portion 235 connected in sequence. The first connecting portion 231 and the second connecting portion 235, as well as the first spiral portion 232 and the second spiral portion 234, are all spaced apart along a first direction; the first connecting portion 231 or the second connecting portion 235 and the snap-fit ​​portion 233 are spaced apart along a second direction. The first connecting portion 231 and the second connecting portion 235 are both connected to the fixing base 21, and the snap-fit ​​portion 233 snaps into the pressure cap 22; the first direction and the second direction form an angle.

[0043] In other words, the first spiral portion 232 and the second spiral portion 234 can provide torque for the movement of the first connecting portion 231 and the second connecting portion 235, causing the fixed seat 21 to swing relative to the pressure plate to match the specific movement of the waist and back. By fixing the first connecting portion 231 and the second connecting portion 235 to the fixed seat 21, the stability during the twisting process can also be improved; and the snap-fit ​​portion 233 can also facilitate the installation and removal of the pressure cover 22.

[0044] It should be noted that in this embodiment, the two lumbar supports 30 are spaced apart along a third direction, wherein the first direction, the second direction, and the third direction are perpendicular to each other. It is easy to understand that the first direction can be understood as the length direction of the lumbar support 30, the second direction as the thickness direction of the lumbar support 30, and the third direction as the width direction of the lumbar support 30.

[0045] Furthermore, it should be noted that in some other embodiments, only the first connecting part 231, the first spiral part 232 and the snap-fit ​​part 233 may be provided for cooperation, or only the snap-fit ​​part 233, the second spiral part 234 and the second connecting part 235 may be provided for cooperation, which can also enable the fixed seat 21 to drive the waist support 30 to swing.

[0046] Please refer to Figure 7 , Figure 7 This is a schematic diagram of the structure of the pressure cap 22 provided in this embodiment, combined with... Figures 5-7 The pressure cap 22 has a slot 221 on the side near the mounting fastener 10, and the locking part 233 is disposed in the slot 221. By placing the slot 221 on the side of the pressure cap 22 near the mounting fastener 10, after the mounting fastener 10 is connected to the pressure cap 22, the locking part 233 can be stably fixed between the mounting fastener 10 and the pressure cap 22, ensuring that the elastic torsion member 23 can better apply torque to the lumbar support 30, thereby improving the support performance of the lumbar support assembly 100.

[0047] Furthermore, the slot 221 includes a first bending groove 2211, a horizontal groove 2212, and a second bending groove 2213 connected in sequence. The engaging portion 233 includes a first bent section 2331, a horizontal section 2332, and a second bent section 2333 connected in sequence. The first bent section 2331 is disposed in the first bending groove 2211, the horizontal section 2332 is disposed in the horizontal groove 2212, and the second bent section 2333 is disposed in the second bending groove 2213. The first spiral portion 232 is connected to the first bent section 2331, and the second spiral portion 234 is connected to the second bent section 2333.

[0048] Combination Figures 4-7 To further improve the installation stability of the snap-fit ​​part 233, the elastic torsion structure 20 also includes a connecting plate 26 and at least one third fastener 27. The connecting plate 26 is disposed on the side of the mounting fastener 10 away from the waist support 30. At least one third fastener 27 is sequentially inserted through the connecting plate 26 and the mounting fastener 10 and connected to the pressure cover 22.

[0049] Furthermore, one end of the pressure cap 22 is provided with a first clearance notch 222 and a second clearance notch 223. The first clearance notch 222 and the second clearance notch 223 are spaced apart along the first direction. The two ends of the slot 221 are respectively connected to the first clearance notch 222 and the second clearance notch 223. A part of the first spiral part 232 is located in the first clearance notch 222, and a part of the second spiral part 234 is located in the second clearance notch 223.

[0050] By setting the first clearance notch 222 and the second clearance notch 223, on the one hand, the first spiral part 232 and the second spiral part 234 can be avoided, so as to prevent the pressure cover 22 from interfering with the elastic torsion member 23 during use; on the other hand, the distance between the pressure cover 22 and the fixed seat 21 can be reduced, thereby improving the overall compactness and structural stability of the elastic torsion structure 20 and further ensuring the support effect of the lumbar support 30.

[0051] Please refer to Figure 8 , Figure 8 This is a schematic diagram of the structure of the fixing base 21 provided in this embodiment, combined with... Figures 4-8 The fixing base 21 has a first fixing protrusion 211 and a second fixing protrusion 212 on the side near the pressure cover 22. The first fixing protrusion 211 and the second fixing protrusion 212 are spaced apart along a first direction. The elastic torsion structure 20 also includes a first fastener 24 and a second fastener 25. The first connecting part 231 is connected to the first fixing protrusion 211 through the first fastener 24, and the second connecting part 235 is connected to the second fixing protrusion 212 through the second fastener 25.

[0052] By setting the first fixing protrusion 211 and the second fixing protrusion 212, it is easy to connect with the first fastener 24 and the second fastener 25, thereby improving assembly efficiency and connection stability of the first connecting part 231 and the second connecting part 235.

[0053] It should be noted that in this embodiment, both the first fastener 24 and the second fastener 25 are screws, and one end of both the first connecting part 231 and the second connecting part 235 is provided with a ring buckle. The screw passes through the ring buckle and connects with the fixing protrusion, thereby realizing the connection and fixation between the elastic torsion member 23 and the fixed seat 21.

[0054] Furthermore, in order to facilitate the installation of the first fastener 24 and the first connecting part 231, the first fixing protrusion 211 is provided with a first mounting groove 2111 and a third clearance notch 2112. The first mounting groove 2111 and the third clearance notch 2112 are connected. A part of the first connecting part 231 is located in the first mounting groove 2111, and the other part passes through the third clearance notch 2112.

[0055] Similarly, in order to facilitate the installation of the second fastener 25 and the second connecting part 235, the second fixing protrusion 212 is provided with a second mounting groove 2121 and a fourth clearance notch 2122. The second mounting groove 2121 and the fourth clearance notch 2122 are connected. A part of the second connecting part 235 is located in the second mounting groove 2121, and the other part passes through the fourth clearance notch 2122.

[0056] It should be noted that, specifically in this embodiment, the first fastener 24 is connected and fixed to the bottom wall of the first mounting groove 2111, and the second fastener 25 is connected and fixed to the bottom wall of the second mounting groove 2121.

[0057] Please continue to combine Figure 5 The lumbar support 30 has an elastic soft surface structure 31 covering its surface, which can improve user comfort. In addition, the elastic soft surface structure 31 also has multiple ventilation holes 32, which can further improve user comfort.

The at least two lumbar supports 30 are spaced apart from the mounting fastener 10, and each lumbar support 30 is connected to the mounting fastener 10 via the elastic torsion structure 20. The lumbar supports 30 are used to drive the elastic torsion structure 20 to twist under external force, allowing them to swing relative to the mounting fastener 10. Furthermore, the elastic torsion structure 20 is used to drive the lumbar supports 30 to swing back to their initial state when the external force is removed. In use, the user's lower back rests against the lumbar supports 30. When the lower back twists, the lumbar supports 30 exert a force on the elastic torsion structure 20, allowing the lumbar supports 30 to move with the lower back. Under the torsion of the elastic torsion structure 20, the lumbar supports 30 are able to fit tightly against the lower back, improving support and providing cushioning elasticity, thus enhancing support performance.
