Description

Technical Field

[0001] The utility model relates to the technical field of seats, in particular to an adjustable seat armrest. Background Art

[0002] In current furniture design, seats, as an indispensable component of daily life and work, are receiving increasing attention for their comfort and functionality. Traditional seat designs often focus solely on basic sitting and lying functions, overlooking users' needs for versatility and adaptability. This is especially true in specialized scenarios, such as home theaters, study rooms, and offices, where users often demand seats that offer greater convenience and comfort.

[0003] To meet users' diverse demands for seating functionality, a number of adjustable chair designs have emerged on the market. However, these designs mostly focus on factors such as seat height and backrest tilt, with relatively little attention paid to armrest design. Traditional armrests are often fixed to the seat base and cannot be adjusted to suit user needs, which to some extent limits the adaptability and comfort of the chair.

[0004] To solve the above problems, the Chinese patent application number 202111108975.2 discloses a seat with flippable armrests. The above-mentioned flippable armrest seat includes a seat body, the seat body includes a seat cushion, an armrest and a self-locking angle adjustment mechanism, and the armrest is hinged to the seat cushion through the self-locking angle adjustment mechanism. The self-locking angle adjustment mechanism includes a first connecting member connected to the seat cushion and a second connecting member connected to the armrest. The first connecting member and the second connecting member are hinged, and a plurality of slots are evenly arranged on the edge of the first connecting member around its hinge center. A clip-on member that cooperates with the multiple slots is slidably provided in the second connecting member. Chinese patent application number 202111244122.1 discloses a fabric sofa with adjustable armrest width. The fabric sofa with adjustable armrest width disclosed above includes a sofa body, a first seat cushion and a second seat cushion are laterally provided on the top surface of the sofa body, and a pressure-relieving cushion and a massage neck pillow are obliquely provided on the side of the backrest frame on the rear side of the sofa body. An armrest bag is provided on the side of the armrest frame outside the pressure-relieving cushion, and a control dial is provided on the side of the armrest frame near one end of the first seat cushion and the second seat cushion. A wear-resistant rubber pad is provided on the side of the folding frame below the armrest bag, and a first folding link is provided at one end of the combined inner wall of the wear-resistant rubber pad and the folding frame. A second folding link is obliquely provided on the inner wall of the folding frame away from one end of the first folding link. The sides of the first folding link and the second folding link away from one end of the inner wall of the folding frame are interconnected by an axle pin and are provided with four arc support plates.

[0005] In the above-mentioned prior art disclosed, the armrest is hinged to the seat cushion through a self-locking angle adjustment mechanism, and the self-locking angle adjustment mechanism includes a first connecting member and a second connecting member, and the first connecting member and the second connecting member are hinged. The armrest can adjust the angle of the armrest through the cooperation of the first connecting member and the second connecting member; however, in the prior art, the adjustment angle of the armrest is limited, and the armrest can only be flipped outward to a certain angle to make the armrest in an inclined state, and when the user's arm is placed on the armrest, the arm is easy to slip off the armrest, so that the armrest cannot provide effective support for the arm, reducing the user's comfort. Utility Model Content

The adjustment of the flip angle of the armrest 2 is achieved by a hinge 4 arranged between the armrest 2 and the base 1. At the same time, the armrest 2 is self-locked at different angles under the action of the hinge 4, thereby meeting the requirements for the armrest angle; in addition, an extension frame 3 is connected to the armrest 2, and the extension frame 3 is connected to the armrest 2 by a hinge 4, and the flip adjustment of the extension frame 3 is achieved, so that the extension frame 3 can be adjusted to a horizontal state, and the arm is placed on the extension frame 3, thereby achieving a supporting effect on the arm, ensuring that the arm will not slip on the extension frame 3, improving the comfort of the armrest, and thus improving the user experience.

[0032] A connecting column 201 and a connecting hole 202 are respectively provided at both ends of the handrail frame 2. The connecting column 201 and the connecting hole 202 are both used to connect the hinge 4. Furthermore, the connecting column 201 is located on the longer end of the handrail frame 2, and there are two connecting columns 201, and they are respectively located at the edges of the ends of the handrail frame 2; the connecting hole 202 is provided on the shorter end of the handrail frame 2, and there are also two connecting holes 202, and the two connecting holes 202 are also located at the edges of the ends of the handrail frame 2; the hinge 4 is installed on the handrail frame 2 by connecting with the connecting column 201. In addition, the hinge 4 on the extension frame 3 is connected to the connecting hole 202.

[0033] Both ends of the base 1 are provided with mounting columns 102 for installing the hinges 4. Furthermore, two mounting columns 102 are provided on each end of the base 1. The two mounting columns 102 correspond to the two hinges 4 on the handrail frame 2, and are connected to the mounting columns 102 through the hinges 4, thereby realizing the installation of the handrail frame 2.

[0034] The base 1 is provided with several fixing parts 101 for fixing the base 1, and the fixing parts 101 are formed with holes 1011 for fixing the base 1. Furthermore, the several fixing parts 101 are distributed on both sides of the base 1, and the several fixing parts 101 are arranged on the inner side of the base 1.
