Technical Field

[0001] This utility model relates to the field of dining chair technology, and in particular to an ergonomic dining chair. Background Technology

[0002] As living standards improve, people's demands for furniture have gone beyond basic functionality; they now seek a balance between artistic beauty, cultural connotation, and user comfort. As a common piece of furniture in daily life, the design of dining chairs is of paramount importance.

[0003] The current design of dining chairs on the market has the following problems and shortcomings:

[0004] 1. Design homogenization is serious and lacks cultural connotation: Many dining chair designs focus on standardization and mass production, with monotonous shapes and rigid styles, lacking unique cultural connotations and artistic value, and failing to meet consumers' growing demand for personalized and emotional consumption.

[0005] 2. Insufficient application of ergonomics and need to improve comfort: The armrest design of some dining chairs does not fully consider the natural curve of the human arm, which may cause discomfort when leaning against it for a long time; the seat cushion is mostly filled with a single material, and the support is unevenly distributed, which can easily lead to fatigue after sitting for a long time.

[0006] 3. Poor integration of structure and aesthetics: Some dining chairs with unique design language often have complex structures or fail to effectively integrate design elements (such as natural curves) with the supporting structure, resulting in a contradiction between visual effect and structural stability.

[0007] In conclusion, it is necessary to design a dining chair that is rich in cultural imagery, ergonomic, and structurally sound, in order to overcome the aforementioned shortcomings of existing technologies. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-3 An ergonomic dining chair includes armrests 1, backrest 2, frame 3, legs 4, and seat 5. The armrests 1 and backrest 2 are integrally formed curved structures. The backrest 2 is located in the middle of the armrests 1. The frame 3 is located between the armrests 1 and the legs 4. The inner side of the legs 4 is provided with support rods 6. The seat 5 is located on the support rods 6. The seat 5 is provided with a cushion 7. The backrest 2 is provided with a backrest 8.

[0024] This utility model discloses an ergonomic dining chair whose overall shape mimics the natural curves of a sycamore branch. It mainly includes armrests 1, a backrest 2, a frame 3, legs 4, and a seat 5. The armrests 1 and backrest 2 form an integral, streamlined curved structure, which constitutes the core load-bearing frame 3 of the chair. The curved structure of the armrests 1 is designed according to the natural downward posture of the human arm, providing continuous support. The backrest 2 is located in the middle of the armrests 1 on both sides, allowing the user to lean back comfortably. The frame 3 is located between the armrests 1 and the legs 4, forming the core load-bearing structure together with the armrests 1 and backrest 2. The legs 4 support the entire chair, with support rods 6 on their inner sides and the seat 5 on the upper side of the support rods 6. The support rods 6 and seat 5 provide support and fixation. A seat cushion 7 and a backrest 8 are respectively placed on the seat 5 and backrest 2. The backrest 8 is located above the backrest 2 and is curved, conforming to the user's back to ensure comfort.

[0025] When a user sits down, their back rests against the backrest 2. The pressure exerted by the back on the backrest 2 is directly transmitted to the armrest 1 and frame 3 through the one-piece continuous curved surface structure, forming a uniform distribution of force. The user's arm weight is applied to the curved surface of the armrest 1, which transmits the load to the frame 3 through its connection with the backrest 2, dispersing the pressure. The seat cushion 7 on the seat surface 5 undergoes coordinated deformation when bearing the weight of the human body. Among them, the support rod 6 on the lower side of the seat surface 5 mainly provides elastic reaction force to resist compression, while the seat surface 5 undergoes adaptive deformation to increase the contact area. The two work together to achieve pressure dispersion and buffering.

[0026] In a preferred embodiment, refer to Figure 1-3The ergonomically designed dining chair has two support rods 6, which are arranged in a cross configuration. The two support rods 6 are connected by mortise and tenon joints or by connectors. The support rods 6 support the chair seat 5. The two chair legs 4 on the diagonal are connected together by a support rod 6. The middle part of the two cross-arranged support rods 6 is connected by a mortise and tenon structure. The specific structure and shape of the mortise and tenon structure are the same as or similar to existing ones, so they will not be described in detail here. Alternatively, connectors such as screws, bolts, or rivets can be used to connect the middle parts of the two support rods 6.

[0027] In a preferred embodiment, refer to Figure 1-3 The ergonomic dining chair has four legs 4. The upper ends of the two legs 4 on the left are connected together by the left frame 3, and the upper ends of the two legs 4 on the right are connected together by the right frame 3. A crossbar 9 is provided between the two legs 4 on the rear side. The lower end of the backrest 2 extends to the back of the crossbar 9 and is connected to it. The backrest 2 is tilted outward, and the angle with the crossbar is greater than 90°.

[0028] The chair legs 4 support the chair body. The upper end of the chair legs 4 is connected to the frame 3, and the upper end of the frame 3 is connected to the armrest 1. A crossbar 9 is set between the two chair legs 4 at the rear to ensure the overall stability of the dining chair. The backrest 2 is a long strip structure, with its lower end extending to the back of the crossbar 9 and then connected to the crossbar 9 through a connector to further ensure the stability of the backrest 2 when leaning back. By setting the backrest 2 to an outward tilting structure with an angle greater than 90° with the crossbar 9, it ensures that the user can recline backward, improving the comfort when sitting and meeting the needs of ergonomics.

[0029] In a preferred embodiment, refer to Figure 1-3 The ergonomically designed dining chair features armrests 1, backrest 2, frame 3, legs 4, and seat 5 made of wood. The seat cushion 7 and backrest cushion 8 consist of an outer soft covering layer and an inner soft padding layer, the latter being made of a composite of elastic materials. An arc-shaped groove 11 is located on the lower front side of the armrest 1.

[0030] The seat cushion 7 and back cushion 8 of this dining chair adopt a multi-layer structure. The soft cushion layer is made of composite materials with different densities and elasticities, which conforms to the curves of the human body, ensuring even distribution of support and reducing fatigue from prolonged sitting. By setting an arc-shaped groove 11 on the front side of the armrest 1, it ensures that the user can grip the armrest 1 when placing their hands on it, thus improving comfort.

[0031] This invention, by mimicking the curves of a sycamore branch and leaf and employing a streamlined, one-piece molded handrail design, presents a natural and flowing aesthetic, significantly enhancing its artistic value and cultural connotation. Actual testing shows that this one-piece molded frame structure, while maintaining the same load-bearing strength (static load test ≥1100N), reduces connecting parts by approximately 30% compared to traditional spliced ​​structures. This not only simplifies the production process but also fundamentally enhances the overall integrity and stability of the structure.

[0032] In terms of comfort, the ergonomically designed continuous curved armrests and layered cushions work synergistically. The combination of a high-density support base layer and a low-elasticity surface layer, as shown in pressure distribution tests, can disperse approximately 25% of the peak pressure in the ischial tuberosity area, significantly reducing fatigue from prolonged sitting. The overall solution successfully achieves an organic unity of artistic form, structural function, and user comfort, providing new ideas for furniture design.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
