[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are for illustrative purposes only and do not represent the only implementation method.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains; the terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention; the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] like Figure 1 and Figure 2 As shown, a multifunctional office leisure chair with lumbar support adjustment function includes a backrest body 1, an adjustment structure 2 is provided inside the backrest body 1, a support frame 11 corresponding to the backrest body 1 is provided inside the backrest body 1, sliding grooves 12 are provided on both sides of the support frame 11 that penetrate the backrest body, and a connecting block 13 is provided on the outside of the sliding groove 12. The adjustment structure 2 includes a sliding shaft 21 placed inside the backrest body 1, and a plurality of stacked adjustment plates 22 are provided on the outside of the sliding shaft 21. The adjustment plates 22 are provided with torsion springs 23 fixedly connected to the backrest body.

[0026] In this embodiment, the utility model patent describes an adjustment structure for a seat backrest, which is designed to adapt to the user's back contour and leaning angle. An adjustment structure 2 is embedded in the backrest body 1. When the user leans on it, the adjustment piece 22 can rotate through the rotation of the sliding shaft 21. This design enables different adjustment pieces 22 to deflect accordingly according to the user's back shape and leaning angle, so that the surface of the backrest body 1 in contact with the user can produce corresponding deformation to enhance adaptability. In addition, the sliding shaft 21 can also drive the adjustment piece 22 to adjust the height position as a whole to change the position and height of the support to provide better comfort and support.

[0027] It should be noted that the present invention mainly relates to the lumbar support part of the seat. As for the functions of the seat under the existing technology or the filling in the backrest body 1, technicians and production personnel in this field can make their own choices according to production needs.

[0028] like Figure 3 and Figure 4 As shown, the connecting block 13 is provided with a locking pin 14 that passes through the connecting block and is inserted into the interior of the sliding shaft 21. The locking pin 14 corresponds to the sliding groove 12. The sliding shaft 21 passes through the non-center position of the adjusting piece 22. A partition 24 is provided between the adjusting pieces 22 and is penetrated by the sliding shaft 21. The partition 24 and the adjusting piece 22 are provided with corresponding grooves 25. The grooves 25 correspond to the torsion spring 23. The two ends of the torsion spring 23 are fixedly connected to the grooves 25 on the partition 24 and the adjusting piece 22 respectively.

[0029] In this embodiment, the locking pin 14 secures the position of the sliding shaft 21 within the sliding slot 12, preventing unwanted movement of the adjustment plate 22 during adjustment. When the user needs to adjust the strength of the lumbar support, they can operate the locking pin 14 to secure or release the movement of the sliding shaft 21, thereby precisely controlling the position of the adjustment plate 22. The torsion spring 23 is designed to provide a restoring force to the adjustment plate 22, allowing it to automatically return to its initial position without external forces. This design helps provide a natural, dynamic support that automatically adjusts the support strength according to the user's movements and posture. The partition 24 is an intermediate component connecting adjacent adjustment plates 22. It not only serves as a connection but also, together with the groove 25, forms a fixed structure for the torsion spring 23. The groove 25 on the partition 24 corresponds to the groove 25 on the adjustment plate 22, ensuring stable installation and effective function of the torsion spring 23. Furthermore, the stacked arrangement of the adjustment plates 22 allows the backrest body 1 to provide varying degrees of support in different areas. For example, the adjustment piece 22 in the waist area may be harder or denser than the adjustment piece in other areas of the back to provide stronger support. This design takes into account ergonomic principles and is intended to provide the user with optimal comfort and support.

[0030] When in use, first, the user needs to adjust the office leisure chair to the appropriate position, ensuring that the seat and backrest body 1 of the chair can comfortably support the user's sitting posture. The user sits down and leans on the backrest body 1. At this time, the adjustment structure 2 inside the backrest begins to work, and the adjustment piece 22 is adaptively adjusted according to the user's back contour and leaning angle. If the user feels that the lumbar support is insufficient or too strong, the adjustment handle on the side of the chair is not mentioned in the original text, but usually such chairs are equipped with an adjustment to adjust the locking pin 14. Rotating the adjustment handle will cause the locking pin 14 to move along the sliding groove 12, thereby changing the position of the sliding shaft 21. When the adjustment handle is rotated to adjust the position of the locking pin 14, the sliding shaft 21 is fixed or released. If the user wants to fix the current support strength, insert the locking pin 14 into the corresponding sliding groove 12 position to fix the sliding shaft 21. If the user wishes to release the adjustment plate 22 for finer adjustments, the locking pin 14 can be loosened. The user can fine-tune the position of the adjustment plate 22 by slightly changing the sitting posture, leaning strength, or directly operating the adjustment handle to achieve the best lumbar support effect. The design of the torsion spring 23 enables the adjustment plate 22 to provide dynamic support, automatically adapting to the user's movements and posture changes. Once the user finds the most comfortable support position and strength, the sliding shaft 21 can be fixed in the current position through the locking pin 14 to ensure that the adjustment plate 22 will not shift during long-term use. After completing the above steps, the user can enjoy the customized lumbar support provided by the multifunctional office leisure chair to improve comfort while working and reduce physical fatigue caused by long-term sitting and working.

[0031] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Anyone familiar with this technology may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
