[0017] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] Reference Figures 1-4 An embodiment of the present invention provides a motorcycle seat with an adjustable backrest, including a mounting base 1, a leather cover 2, a backrest 3 and a decorative piece 4, wherein an adjustment component is provided between the mounting base 1 and the backrest 3. The adjustment assembly includes a mounting bracket 501, a first support base 502, a second support base 503, a joint hinge 504, a first fixing screw 505, and an adjustment frame 506. The mounting bracket 501 is fixedly mounted inside the mounting base 1 by bolts. The first support base 502 and the second support base 503 are fixedly connected to the top of the mounting bracket 501. The joint hinge 504 is located on the top of the first support base 502 and the second support base 503. One end of the first fixing screw 505 is fixedly connected to the bottom of both ends of the joint hinge 504. One end of the adjustment frame 506 is fixedly mounted on the connecting end of the joint hinge 504. The first support base 502 and the second support base 503 have mounting holes in their middle sections that match the first fixing screw 505. The adjustment frame 506 is fixedly mounted on the top of the first support base 502 and the second support base 503 through the engagement of the first fixing screw 505 with the mounting holes. The adjustment frame 506 is U-shaped. The metal frame is fixedly connected to the inner wall of the backrest 3 by a plurality of evenly distributed bolts. The leather sleeve 2 is fixedly installed on the top of the mounting base 1, and the leather sleeve 2 has an adaptation opening corresponding to the position of the adjustment frame 506.

[0020] Among them, the joint hinge 504 belongs to the sofa seat hinge, also called the angle adjustment hinge. It is mainly used in furniture such as sofas with adjustable backrests and fishing chairs with adjustable backrests. Its model is HXM1507 or KY-301, which is a five-position 180-degree seat hinge.

[0021] It should be noted that both the adjustment frame 506 and the mounting frame 501 can be made of high-strength alloy steel U-shaped frame, such as Q235 steel. The first support seat 502 and the second support seat 503 are welded to the mounting frame 501. The edge of the fitting opening of the leather sleeve 2 corresponding to the adjustment frame 506 is sealed with PU rubber strip. This not only prevents the adjustment frame 506 from scratching the leather sleeve 2 during angle adjustment, but also prevents dust and rainwater from entering the interior of the mounting seat 1 through the opening gap. The joint hinge 504 is equipped with a spring anti-loosening washer at the connection end with the first fixing screw 505. After tightening the screw nut, the washer can generate a continuous pre-tightening force through elastic deformation, which effectively prevents the connection between the screw and the support seat from loosening due to vibration when the motorcycle is traveling at high speed or on bumpy roads. This ensures the stability of the backrest 3 and avoids the safety hazards caused by the unexpected displacement of the backrest 3 during driving.

[0022] In some embodiments, such as Figure 2 As shown, a fixing hole 601 is provided in the middle of the leather sleeve 2. The fixing hole 601 passes through the bottom of the mounting base 1. The bottom of the decorative part 4 is fixedly connected to a second fixing screw 602 that is compatible with the fixing hole 601. The decorative part 4 is fixedly installed on the top of the leather sleeve 2 through the cooperation of the second fixing screw 602 and the fixing hole 601. The decorative part 4 is located at one end of the joint hinge 504.

[0023] It should be noted that the purpose of setting the fixing hole 601 and the second fixing screw 602 is to install the decorative part 4. The decorative part 4 is used to cover the joint hinge 504 of the adjustment component to avoid causing discomfort to the passenger.

[0024] In practical applications, when in use, the driver holds the backrest 3 and uses the connection point between the adjustment frame 506 and the joint hinge 504 as the rotation point. The multi-position adjustment of the joint hinge 504 is used to achieve the angle suspension of the backrest 3, which can flexibly adjust the tilt angle and support position of the backrest 3 to adapt to the lumbar support needs of drivers of different heights and body types. This allows the driver's waist to fit against the backrest 3 while riding, significantly relieving fatigue during long rides. When not in use, the backrest 3 can also be laid flat against the end of the leather cover 2 for support. The adjustment process requires no tools and is easy to use.

[0025] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
