[0028] Example

[0029] Depend on Figure 1 , Figure 3 As shown, this utility model embodiment provides an adjustable seat width armrest structure, including an upper armrest assembly 2, a lower armrest assembly 1, a sliding assembly 3, and a positioning member 4. The lower armrest assembly 1 is used to connect to the seat body 5, and has a mounting portion 11 adapted to the shape of the seat body 5. The mounting portion 11 has a first mounting surface 12 and a second mounting surface 13, which are flush with the seat plate and backrest of the seat body, respectively, thereby preventing the mounting surfaces from protruding from the seat body and affecting the comfort of the massage chair. The upper armrest assembly 2 is slidably connected to the mounting portion 11 via the sliding assembly 3, allowing the upper armrest assembly 2 to slide horizontally in a direction away from or towards the seat body to adjust the seat width. The positioning member 4 can position the sliding assembly 3 when the upper armrest assembly 2 slides to a designated position to fix the upper armrest assembly 2.

[0030] In this embodiment, the user can adjust the seat width by sliding the upper armrest assembly 2 away from or closer to the seat body. Once a comfortable seat width is achieved, the sliding assembly is positioned by a positioning component to fix the upper armrest assembly 2 and maintain the comfortable seat width. Through the armrest structure of this application, the seat width of the massage chair can be adjusted to meet the different comfort requirements of various users, thereby improving the comfort of the massage chair and enhancing the user experience.

[0031] Specifically, the sliding assembly 3 includes a mating slider 31 and a mating base 32. The mating slider 31 is bolted to the upper handrail assembly 2, and the mating base 32 is screwed to the mounting portion 11 of the lower handrail assembly 1. The mating base 32 is provided with a sliding groove that matches the mating slider 31. The mating slider 31 is slidably connected in the sliding groove, thereby allowing the upper handrail assembly 2 to be slidably connected to the mounting portion 11 of the lower handrail assembly 1.

[0032] The sliding member 31 has a positioning hole 33, and the base 32 has several adjustment holes 34. The positioning element 4 is a bolt, and each of the adjustment holes 34 has an internal thread that matches the bolt. The upper armrest assembly 2 is slid up so that the positioning hole 4 coincides with one of the adjustment holes 34, and then the bolt is screwed in to position the sliding member 33 and fix the upper armrest assembly 2. To readjust the seat width, the bolt is unscrewed, and the upper armrest assembly 2 is slid up again. In this embodiment, two adjustment holes 34 are provided, but more can be provided to achieve more width adjustments. It is understood that the positioning element 4 can be a positioning pin, or a ball bearing can be installed on the sliding member 31 for positioning.

[0033] Furthermore, both the sliding member 31 and the base 32 are provided with a clearance portion 35 for avoiding the screw. The clearance portion of the sliding member 31 is upwardly protruding, and the clearance portion of the base 32 is downwardly recessed.

[0034] Furthermore, the sliding member 31 has a wedge-shaped portion 36 at the end away from the seat body 5, and the base 32 has a wedge-shaped groove 37 at the end away from the seat body 5 that matches the wedge-shaped portion 36. During armrest installation, the upper armrest assembly 2 is inserted from the side of the lower armrest assembly 1 away from the seat body 5. The cooperation between the wedge-shaped portion 36 and the wedge-shaped groove 37 limits the sliding of the sliding member, facilitating the installation and positioning of the upper armrest assembly 2. Furthermore, during this limiting state, the seat width of the massage chair is in its initial state.

[0035] Furthermore, there are two sliding components 3. Both the first mounting surface 12 and the second mounting surface 13 are provided with a groove 14. The two sliding components 3 are respectively disposed in the groove 14, so that the upper armrest component 2 can be more stably slidably connected to the lower armrest component 1. And by providing the groove 14, the sliding component 2 can be prevented from protruding from the seat or backrest, thus affecting the comfort of the massage chair.

[0036] Furthermore, the upper armrest assembly 2 is provided with a receiving groove 21 for placing an arm on the side near the seat body 5. Massage components such as massage airbags can be installed in the receiving groove 21 to massage the user's arm.

[0037] Depend on Figure 4 and Figure 5 As shown, this application also provides a massage chair, including a seat body 5 and an adjustable seat width armrest structure as described above. The armrest structure is symmetrically installed on both sides of the seat body 5 via the lower armrest assembly 1.

[0038] Specifically, a number of fasteners 15 are provided on the side of the lower armrest assembly 1 near the seat body 5. The fasteners 15 have connecting holes. The seat body 5 has a number of fixing holes 51 with internal threads. The fasteners 15 are fixedly connected to the fixing holes 51 by screws, thereby installing the armrest structure on the seat body 1.

[0039] The above are embodiments of this utility model. It can be understood that the armrest structure of this application is not only applicable to massage chairs, but also to other backrest chairs to improve the comfort of the backrest chair.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
