[0042] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0043] This utility model proposes an adjustable seat assembly.

[0044] In this embodiment of the utility model, such as Figures 1 to 4 As shown, it includes:

[0045] Seat 1;

[0046] The first guide part 2 is provided on the support body of the dining chair. The extension direction of the first guide part 2 forms an angle with the height direction of the dining chair, which is used to realize the height adjustment of the seat 1.

[0047] The first sliding part 3 is slidably disposed on the first guide part 2, connected to the seat plate 1, and can drive the seat plate 1 to perform linear reciprocating motion along the first guide part 2;

[0048] A first locking mechanism is used to lock the first sliding part 3 and the first guide part 2 at a selected position.

[0049] Specifically, the first guide part 2 is a strip groove provided on the support body of the dining chair;

[0050] The first locking mechanism includes a plurality of insertion holes 21 disposed on the side wall of the strip groove and an insert 31 disposed on the first sliding part 3;

[0051] The plug-in 31 can be selectively inserted into any of the sockets 21 to lock, or withdrawn from the sockets 21 to unlock;

[0052] The plug-in 31 is connected to a button 32, and the plug-in 31 can be exited by operating the button 32.

[0053] This embodiment provides a specific, reliable, and cost-effective guiding and locking method. The strip groove is simple to manufacture and provides stable and reliable guidance. The cooperation between the socket 21 and the plug 31 is a mechanical interlock, resulting in a very stable locked state with strong load-bearing capacity, making accidental unlocking difficult. Unlocking is performed via button 32, a straightforward method that is easy for users to understand and operate, and can be completed with one hand, improving the user experience.

[0054] Specifically, a first spring is also provided, which applies an elastic force to the plug 31 to realize the function of automatically inserting the plug 31 into the socket 21.

[0055] Specifically, the plurality of the insertion holes 21 are spaced apart along the length of the strip groove.

[0056] The jacks 21 are spaced apart to form multiple clearly defined adjustment positions. This design makes the seat adjustment 1 stepped rather than stepless, with the following advantages: 1. It provides users with clear positional feedback, making it easy to find and repeat a previous comfortable position; 2. It simplifies the manufacturing and assembly process; 3. It ensures even force distribution and greater structural stability after each position is locked. The spacing between the positions can be optimized according to different age groups of children and common usage scenarios.

[0057] Specifically, the seat plate 1 and the first sliding part 3 are integrally formed;

[0058] Alternatively, the seat plate 1 and the first sliding part 3 are two independent components, which are connected and locked to each other by a plug-in structure and a fixed structure.

[0059] This application provides embodiments of two connection methods. A one-piece molded structure, for example, formed in one step through injection molding, has the advantages of high strength, high production efficiency, fewer parts, and good overall integrity. A split structure, on the other hand, provides greater flexibility and convenience, such as facilitating the individual disassembly, cleaning, replacement, or transportation of the seat 1, for example, by folding, and also allowing for the use of seat 1s of different materials or shapes, achieving modular design.

[0060] Specifically, when the seat plate 1 and the first sliding part 3 are two independent components,

[0061] The plug-in structure includes a plug-in part 11 provided on the seat plate 1 and a plug-in groove 33 provided on the first sliding part 3. The connection between the seat plate 1 and the first sliding part 3 is realized through the plug-in cooperation of the plug-in part 11 and the plug-in groove 33.

[0062] The fixing structure includes a locking member 12 disposed on the seat plate 1 and a locking hole disposed in the insertion slot 33;

[0063] The locking member 12 can pass through the plug-in part 11 and be inserted into the locking hole to lock the seat plate 1 and the first sliding part 3, or it can be removed from the locking hole to unlock.

[0064] The seat 1 is provided with an unlocking member 13 connected to the locking member 12. By operating the unlocking member 13, the locking member 12 is controlled to exit from the locking hole.

[0065] Specifically, a second spring 14 and a third spring 15 are also provided. The second spring 14 applies an elastic force to the locking member 12 to automatically insert into the locking hole, and the third spring 15 applies an elastic force to the unlocking member 13 to automatically reset.

[0066] This embodiment details the specific locking mechanism of the split-type connection. This pin-type connection method is simple, effective, and reliable. Users can quickly remove the seat 1 from the base by operating the unlocking component 13, such as a pull ring or wrench, without tools, making daily cleaning and maintenance very convenient. Furthermore, this connection method is usually accompanied by a "click" sound or a distinct tactile feedback during installation, providing users with a sense of confirmation that the installation is in place.

[0067] Specifically, foot pedal 4;

[0068] The second guide part 5 is provided on the support body of the dining chair. The extension direction of the second guide part 5 forms an angle with the height direction of the dining chair, and is used to realize the height adjustment of the foot pedal 4.

[0069] The second sliding part 6 is slidably disposed on the second guide part 5, connected to the foot pedal 4, and can drive the foot pedal 4 to perform linear reciprocating motion along the second guide part 5;

[0070] The second locking mechanism is used to lock the second sliding part 6 and the second guide part 5 at a selected position.

[0071] This embodiment extends the adjustable concept to the footrest 4. For children's high chairs or users who need to rest their feet, the height adjustment of the footrest 4 is crucial, directly affecting seating comfort and leg support. By employing a sliding and locking structure based on the same principle as the seat 1 adjustment, independent adjustment of the footrest 4 is achieved, allowing it to adapt to the leg lengths of children of different heights and growth stages, ensuring good posture and comfort. This symmetrical design also simplifies production and assembly.

[0072] Specifically, the first guide section 2 and the second guide section 5 are two independent strip grooves;

[0073] Alternatively, the first guide portion 2 and the second guide portion 5 may be the upper and lower sections of the same strip groove, respectively.

[0074] This embodiment provides two layout schemes for the guide section. Using two independent strip slots with insertion holes 21 allows for completely independent adjustment of the seat 1 and footrest 4, preventing interference and resulting in higher structural strength. This is suitable for products with high stability and load-bearing requirements, as well as seats that need to be folded. Using the upper and lower areas of a single strip slot saves materials, simplifies the structural design of the support structure, and reduces manufacturing costs and weight. This is suitable for products that prioritize cost-effectiveness, as well as non-foldable products. These two schemes provide options for different product positioning and design needs.

[0075] Specifically, the first locking mechanism and the second locking mechanism operate in the same way.

[0076] This design emphasizes consistency in user experience. Whether adjusting the seat 1 or the footrest 4, the user uses the same operating method—for example, pressing the same type of button to operate the same type of latch to insert or retract from the socket 21 to lock or unlock. This significantly reduces the learning curve for users, avoids confusion, makes the adjustment process more intuitive and convenient, and improves the overall usability of the product.

[0077] Specifically, the connection method between the foot pedal 4 and the second sliding part 6 is the same as the connection method between the seat 1 and the first sliding part 3.

[0078] This design achieves a high degree of modularity and component commonality. The seat 1 and footrest 4 can use the same or similar connection interfaces, such as one-piece molding or the same plug-in locking structure. The benefits of this include: reducing the number of parts, lowering supply chain management and inventory costs, simplifying the assembly process, and facilitating after-sales maintenance and parts replacement. From a design aesthetic perspective, it also maintains consistency in product style.

[0079] Specifically, the first guide portion 2 and the first sliding portion 3 are a pair arranged at left and right intervals;

[0080] The two first sliding parts 3 are respectively connected to the left and right sides of the seat plate 1;

[0081] The second guide portion 5 and the second sliding portion 6 are both a pair arranged at left and right intervals;

[0082] The two second sliding parts 6 are respectively connected to the left and right sides of the foot pedal 4.

[0083] This embodiment optimizes the layout of the guide and sliding structures. By employing a pair of symmetrically arranged guide and sliding parts, which jointly bear the load of the seat 1 and footrest 4, the stability, balance, and load-bearing capacity of the entire assembly during adjustment and use are greatly enhanced. This effectively prevents jamming, wear, or structural deformation problems that may be caused by unilateral force, and is particularly suitable for dining chair products that need to withstand greater weight or require higher safety.

[0084] This application also claims protection for a dining chair that includes the aforementioned adjustable seat assembly.

[0085] This dining chair possesses all the excellent features of the aforementioned adjustable seat assembly, including adjustable seat height 1, adjustable footrest 4, and detachable seat 1 and footrest 4.

[0086] This type of dining chair can better adapt to different users and different usage scenarios, such as the need to match dining tables of different heights, providing better comfort and convenience, and has a clear competitive advantage in the market compared to traditional fixed dining chairs.

[0087] This utility model's technical solution achieves linear reciprocating movement of the seat relative to the main support body of the dining chair through the sliding cooperation of the first sliding part and the first guide part, allowing the seat height to be flexibly adjusted according to the user's needs. The first locking mechanism reliably locks the first sliding part and the first guide part at a selected position, ensuring the seat remains stable in any adjusted position, providing good load-bearing capacity, preventing accidental displacement during use, and ensuring high safety and reliability. The entire component structure has a clear principle, few parts, and is easy to manufacture and assemble. While providing practical adjustment functions, it effectively controls manufacturing costs, facilitating market promotion.

[0088] 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. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
