Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sofas and relates to a cushion component in an adjustable sofa. Background Art
[0002] The sofa is a kind of furniture commonly found in various living spaces, mainly placed in living rooms, study rooms, etc. It not only provides people with a comfortable place to rest and relax, but also often becomes an important part of home decoration, which can enhance the overall home atmosphere.
[0003] The sofa cushion components currently on the market are usually composed of a headrest and a backrest, and their positions are usually fixed and cannot be adjusted according to personal needs. Therefore, it is necessary to design an adjustable sofa cushion component. Summary of the Invention
[0004] The purpose of the utility model is to solve the above problems in the existing technology and to provide an adjustable sofa cushion assembly.
[0005] The purpose of the utility model can be achieved through the following technical solutions: a pillow assembly in an adjustable sofa, the pillow assembly includes pillow one and pillow two, characterized in that the height of pillow one is greater than the height of pillow two, the pillow assembly also includes a guide rail, a slider, a connecting seat and an adjustment frame, the guide rail is horizontally installed on the sofa body, the slider is slidably connected to the guide rail, the slider is threaded with a locking screw, the connecting seat is installed on the slider, and the adjustment frame is rotatably connected to the connecting seat via a rotating shaft, the middle part of pillow one is connected to the adjustment frame, and the upper part of pillow one is detachably connected to pillow two via a zipper.
[0006] The upper part of the first backrest pillow is also provided with a shielding cloth strip.
[0007] The adjustment frame is in a V-shape.
[0008] The middle part of the adjustment frame is also provided with an iron positioning piece. The connecting seat is connected with a magnet through a rubber block, and the magnet can cooperate with the iron positioning piece.
[0009] The locking screw is a thumb screw.
[0010] Compared with the prior art, the cushion assembly in the adjustable sofa has the following advantages:
[0011] In this utility model, when the mounting frame is horizontal, backrest 2 is connected to backrest 1 via a zipper and positioned above it, acting as a lumbar support. When the mounting frame is tilted upward, backrest 2 can be removed and placed below backrest 1, creating a larger support surface. Alternatively, backrest 1 can be adjusted backward without using backrest 2, maximizing seat space and providing a temporary play area for children. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0017] like Figure 1-Figure 3 As shown, the pillow assembly in the adjustable sofa includes a pillow 1 2 and a pillow 2 5. The height of the pillow 1 2 is greater than the height of the pillow 2 5. The pillow assembly also includes a guide rail 8, a slider 10, a connecting seat 7 and an adjustment frame 6. The guide rail 8 is horizontally installed on the sofa body 1, and the slider 10 is slidably connected to the guide rail 8. The slider 10 is threaded with a locking screw 9, specifically: the locking screw 9 is a hand screw; the connecting seat 7 is installed on the slider 10, and the adjustment frame 6 is rotatably connected to the connecting seat 7 through a rotating shaft 11. The middle part of the pillow 1 2 is connected to the adjustment frame 6, and the upper part of the pillow 1 2 is detachably connected to the pillow 2 5 through a zipper 4.
[0018] The upper portion of the pillow 2 is further provided with a shielding cloth strip 3. In this embodiment, the shielding cloth strip 3 is used to effectively shield the zipper 4.
[0019] The shape of the adjustment frame 6 is V-shaped. In this embodiment, the middle portion of the adjustment frame 6 is rotatably connected to the connecting seat 7 via a rotating shaft 11, and the middle portion of the headrest 2 is connected to the end portion of the adjustment frame 6.
[0020] The middle part of the adjustment frame 6 also has an iron positioning piece 12, which is connected to the connecting seat 7 through a rubber block 13 and a magnet 14, and the magnet 14 can cooperate with the iron positioning piece 12. With this structure, when the mounting frame is tilted, it plays a limiting role. At the same time, the magnet 14 cooperates with the iron positioning piece 12 to effectively fix the mounting frame.
[0021] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.
[0022] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
