Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to a sofa with an adjustable supporting structure. Background Art

[0002] With economic development and an aging population, the elderly and those who need health care have increasingly higher requirements for products, especially comfort. However, current elderly chairs are ordinary furniture with serious homogeneity. These functions are sufficient for most people with knee problems, but not for some people with moderate disabilities. Medical-grade chairs are also very expensive.

[0003] Current single chairs have three support points, allowing the waist, shoulders, and back of the head to rest on the curved backrest simultaneously. However, this does not provide lateral support to the supported areas during use, and cannot help users maintain the natural curve of the spine and an upright sitting posture.

[0004] At the same time, for those who need additional stability support, traditional single chairs cannot achieve effective support effects, so that users cannot obtain good support and comfort during use, thereby affecting the user's use and failing to provide users with comfortable rest services.

[0005] Therefore, a sofa with an adjustable supporting structure is proposed to solve the current shortcomings. Utility Model Content

[0007] In order to solve the above technical problems, the technical solution provided by the present invention is a sofa with an adjustable support structure: comprising a sofa body and support parts arranged on the upper and lower parts of the backrest of the sofa body;

[0008] The support portion includes a fixing plate and a supporting plate. The fixing plate is fixedly arranged on the sofa body. Both ends of the fixing plate are rotatably connected to the supporting plate through angle adjustment hinges.

[0009] The sofa further comprises a partition plate which is fixedly arranged on the sofa body and is located between the support parts of the upper and lower parts of the backrest of the sofa body.

[0010] As an improvement, the support plate located in the lower support portion is provided with a notch that cooperates with the armrest of the sofa body.

[0011] As an improvement, in the initial state, the fixing plate and the supporting plate are located in the same plane and fit with the sofa body.

[0012] As an improvement, the longitudinal height of the lower support portion is greater than the longitudinal height of the upper support portion.

[0013] The advantages of this utility model compared with the prior art are:

[0014] 1. The support parts located at the upper and lower parts of the sofa body can support the user's head, back and waist. At the same time, the rotation between the support plate and the fixed plate can achieve lateral support for the supported parts, thereby achieving an all-round support effect for the supported parts;

[0015] 2. The sofa has a simple structure and is easy to use and adjust. It can effectively support the user's waist, back and neck when the user is sitting or lying down, achieving all-round support for the supported parts, thereby helping the user maintain the natural curve of the spine and the correct sitting posture, and increasing body comfort.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the utility model more clear, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings herein can be arranged and designed in various different configurations.

[0026] In the description of the embodiments of the utility model, it should be noted that if the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc. appear, the orientation or positional relationship indicated is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use. These terms are only used to facilitate the description of the utility model and simplify the description, and do not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limitations on the utility model. In addition, the terms "first," "second," "third," etc. are used only to distinguish the description and should not be understood as indicating or implying relative importance.

[0027] Furthermore, the use of terms such as "horizontal," "vertical," and "overhanging" does not necessarily imply that the component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0028] In the description of the embodiments of the utility model, "a plurality of" means at least 2.

[0029] In the description of the embodiments of the utility model, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art can understand the specific meanings of the above terms in the utility model based on specific circumstances.

[0030] As shown in the accompanying drawings, a sofa with an adjustable support structure can provide all-round support for the user's upper body through the setting of the support structure. At the same time, the support structure can provide strong lateral support to help the user maintain the natural curve of the spine and the correct sitting posture. In addition, during the process of helping the user to stand up, the support part can also assist the user and give them a greater sense of security.

[0031] The sofa comprises a sofa body 1 and support parts 2 arranged on the upper and lower parts of the backrest of the sofa body 1. In this embodiment, the sofa body 1 is an existing single sofa.

[0032] In a specific implementation, the support part 2 located at the upper part of the backrest of the sofa body 1 is the head support part, which can support the user's head and neck, and the support part 2 located at the lower part of the backrest of the sofa body 1 is the waist support part, which can support the user's back and waist.

[0033] The support portion 2 includes a fixing plate 21 and a support plate 22. The fixing plate 21 is fixedly mounted on the sofa body 1. Both ends of the fixing plate 21 are rotatably connected to the support plate 22 via angle adjustment hinges 23. Specifically, the angle adjustment hinges 23 are conventional, and the angle between the support plate 22 and the fixing plate 21 can be adjusted and the relative angle between the two can be maintained constant, thereby providing lateral support to the supported area.

[0034] At the same time, the support plate 22 located in the lower support part 2 is provided with a notch 24 that cooperates with the armrest of the sofa body 1 to ensure the cooperation between the corresponding support plate 22 and the armrest of the sofa body 1.

[0035] Furthermore, the longitudinal height of the lower support portion 2 is greater than the longitudinal height of the upper support portion 2, which can increase the support area for the waist and back, ensure the support effect for the waist and back, and improve comfort.

[0036] It also includes a partition 3, which is fixed on the sofa body 1 and located between the upper and lower support parts 2 of the backrest of the sofa body 1 to ensure that the upper support part 2 and the lower support part 2 are flush.

[0037] At the same time, in order to ensure the comfort of use of the sofa, the sofa body 1 and the support part 2 are both wrapped with a flexible layer.

[0038] During the specific implementation of the present invention, in the initial state, the fixing plate 21 and the supporting plate 22 are located in the same plane and fit with the sofa body 1 .

[0039] During the adjustment process, the support part 2 located at the corresponding position on the sofa body 1 can be adjusted according to actual conditions to achieve support for different parts. Specifically, the support plates 22 located on both sides of the fixed plate 21 can be pulled up to achieve lateral support for different parts. At the same time, in conjunction with the support of the sofa body 1, the user's waist, back and neck can be effectively supported when the user is in a sitting or lying state, achieving all-round support for the supported parts, thereby helping the user maintain the natural curve of the spine and the correct sitting posture, and increasing body comfort.

[0040] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
