Description

Technical Field

[0001] This utility model relates to the field of seat structure technology, specifically to a seat fixing structure and an automobile seat. Background Technology

[0002] As users demand higher levels of vehicle comfort, some cars are equipped with massage structures in their seats. Users can utilize these massage structures to alleviate fatigue during travel or driving. Existing car seat massage systems mainly consist of components such as airbags, air pumps, control valves, and air hoses. Multiple airbags are arranged along the backrest of the car seat. In use, the air pump generates compressed gas, which is then distributed to different air hoses by the control valves. Finally, the compressed gas is delivered to the corresponding airbags through these hoses, causing them to inflate and deflate to achieve the massage function. Currently, for ease of installation and subsequent control, the airbags, control valves, and air hoses are installed inside the seat backrest. To facilitate and stabilize the installation of the control valves and air hoses, existing technology typically involves fixing felt inside the backrest, then securing the control valve to the felt using screws or similar methods, and finally connecting the air hoses between the control valves and the airbags.

[0003] While existing methods offer convenient and stable installation of the control valve, in actual use, if the massage air tubes are not secured, relative movement and noise may occur when the user leans against the seat back and the backrest deforms. Although existing technologies use clamps or other fixing structures to secure multiple air tubes, installation requires first fixing the clamps to the felt, and then arranging and fixing the air tubes sequentially onto the clamps. This is complex and costly, and the air tubes may loosen from the clamps during use, resulting in inconsistent fixation and affecting the user experience. Utility Model Content

[0004] The present invention aims to provide a seat fixing structure and a car seat to solve the problem that the air tube fixing structure in the existing car seat massage system is complex and easily loosens, thus affecting its use.

[0005] To solve the above problems, the present invention adopts the following technical solution: a seat fixing structure, including a felt body and a control valve fixedly connected to one side of the felt body. The control valve is connected to multiple air pipes. The felt body is provided with multiple fixing units. Each fixing unit includes two slits opened on the felt body. The felt between the two slits elastically protrudes towards the side of the felt body where the control valve is located to form an elastic compression band. A fixing gap is formed between the elastic compression band and the felt body for fixing the air pipes.

[0006] The principle of this solution is as follows: In this application, the control valve is fixedly connected to one side of the felt body, and multiple air tubes are connected to the side of the control valve. The air tubes are used to inflate and deflate the airbags in the prior art. Since the number of airbags may be more than 10, the number of corresponding air tubes is also multiple. Therefore, when fixing the air tubes, in order to ensure neatness and high efficiency of fixing, multiple air tubes on the same side of the control valve are usually fixed at the same time. In this application, when setting up the fixing structure, the air pipes on the same side of the control valve are fixed using fixing units. For the specific structure of the fixing unit, each fixing unit has two slits. The two slits can be parallel to each other or at a certain angle. Since the felt body has good elasticity, when using it, it is only necessary to squeeze the felt part between the two slits toward the side of the felt body where the control valve is set. The felt between the two slits elastically deforms to form an elastic band protruding from one side of the felt body. The elastic compression band and the felt body form a fixed gap. Multiple air pipes are passed through the fixed gap, and then the air pipes are pressed so that all air pipes are arranged along the length of the elastic compression band. The elastic force of the elastic compression band acts on the air pipes, which can conveniently and stably install and fix all air pipes to the felt body.

[0007] The beneficial effects of this plan are:

[0008] 1. Low cost and high efficiency in tracheal tube installation: Compared to existing technologies that use clamps or cable ties to fix trachea, which require additional components and are not only more expensive but also more complex and inefficient, this application directly processes an elastic compression band onto the felt body. Utilizing the excellent elasticity of the felt itself, the elastic compression band provides stable positioning and fixation for multiple trachea tubes, eliminating the need for additional fixing components and effectively saving costs. During installation, simply pull up the elastic band, allowing the trachea to pass through the fixing gap, and then release the elastic band; the elastic compression band automatically fixes the trachea, making tracheal tube installation more convenient and efficient.

[0009] 2. The fixed unit is easy to process: In this application, the fixed unit is a bright strip cut on the felt body. During processing, it can be cut on the felt body with a cutter, which is very convenient.

[0010] 3. Stable fixation effect on trachea: In this application, after multiple tracheas are fixed in the fixed gap, under the elastic force of the elastic compression band, the multiple tracheas are automatically arranged and fixed along the length direction of the elastic compression band. During use, the position of the tracheas is stable, which can play a stable fixation effect on the tracheas and improve the comfort during vehicle use.

[0011] Preferably, as an improvement, the number of tracheas fixed in the fixed gap is N, the diameter of the tracheas is φ, and the length of the fixed gap is L, where L≥(N+1)*φ.

[0012] In this solution, in the massage system of the same vehicle model, the diameter of all air tubes is generally equal. When setting the length of the fixed gap, it is determined according to the number of air tubes to be fixed, and the fixed gap is greater than or equal to the diameter of (N+1) air tubes. This makes the length of the fixed gap greater than the sum of the lengths of all air tubes arranged side by side. On the one hand, this allows for a certain gap in the fixed gap, so that the air tubes can easily pass through the fixed gap and be fixed, making the installation operation more convenient. On the other hand, after all the air tubes are fixed, since the air tubes are fixed against one side of the felt body, the elastic compression band, when pressing and fixing all the air tubes, is set to the length range value in this solution. This ensures that the elastic compression band undergoes appropriate elastic deformation, which not only ensures that all air tubes are stably fixed, but also avoids the elastic compression band being too short and easily damaged by excessive tension during the fixing process, effectively ensuring the stability of the air tube fixing.

[0013] Preferably, as an improvement, in the two parallel slits within the fixing unit, the slit closer to the control valve has a longer length than the other slit.

[0014] In this design, the bright strip slits in the fixing unit are set to be one long and one short, with the longer slit closer to the control valve. When the elastic compression band undergoes elastic deformation, it forms a gap with a larger opening at one end, and the larger opening end is closer to the control valve. When the air tube connected to the control valve is passed through the fixing gap, it enters from the larger opening end and exits from the smaller opening end, making it easier to insert the air tube. The fixing gap, which is larger in the first part and smaller in the second part, can collect the air tubes. Furthermore, when the air tube exits the fixing gap, the width of the fixing gap decreases, allowing the air tubes to be neatly fixed side by side to the felt body.

[0015] Preferably, as an improvement, the distance between the fixed unit near the control valve and the control valve is greater than or equal to 20 mm.

[0016] In actual installation, the control valve and the air pipe are both connected to the same side of the felt body. When the air pipe is connected to the control valve side, the height of the air pipe is generally greater than the diameter of the air pipe itself. Therefore, the connection position of the air pipe and the control valve is in a "suspended" state relative to the side of the felt body. When the air pipe is fixed to the felt body, the air pipe and the side of the felt body are in a mutually close state. Therefore, after the air pipe is connected and led out from the control valve side, it needs to be bent towards the felt body to ensure that the air pipe can be stably fixed by being in close contact with the side of the felt body.

[0017] In this solution, whether one or multiple fixing units are used, the distance between the fixing unit closest to the control valve and the control valve is set to be greater than or equal to 20mm. That is, the air tube is only fixed by the fixing unit after it has been extended at least 20mm from the control valve. This ensures that there is enough distance for the end of the air tube closest to the control valve to bend to the side of the felt body, effectively ensuring the stability of the fixing unit in fixing the air tube. At the same time, it avoids the elastic compression band from exerting tension on the end of the air tube closest to the control valve during the fixing process, which could cause the end of the air tube to loosen.

[0018] Preferably, as an improvement, the elastic extrusion belt has an expansion joint along its length.

[0019] In this solution, expansion joints are made along the length of the elastic extrusion belt, which allows the elastic extrusion belt to undergo more stable elastic deformation along its own length, thereby improving the stability of the elastic extrusion belt.

[0020] Preferably, as an improvement, the width of the fixed gap is greater than or equal to 10 mm.

[0021] In this design, the width of the fixed gap is set to be greater than or equal to 10mm, so that the width of the elastic compression band is large enough to ensure that the elastic compression band can provide a stable compression and fixation effect on all trachea.

[0022] Preferably, as an improvement, the thickness of the felt body is greater than or equal to 2 mm.

[0023] Preferably, as an improvement, the basis weight of the felt body is in the range of 500-600 g / m².

[0024] In this scheme, the thickness of the felt body is set to be greater than or equal to 2mm, and the weight range of the felt body is set to 500-600g / ㎡, so that the felt body has sufficient strength and elastic deformation performance, ensuring that the elastic extrusion belt has good strength and elasticity, and that the elastic extrusion belt can play a stable fixing role for multiple air tubes.

[0025] Preferably, as an improvement, a reinforcing layer is fixedly connected to the felt body. The reinforcing layer is located at both ends of the cut and is perpendicular to the fixing gap, and the two ends of the reinforcing layer protrude from both sides of the fixing gap.

[0026] In this solution, a reinforcing layer is used to structurally strengthen both ends of the elastic compression band, reducing the risk of tearing and damage to the ends of the elastic compression band from the felt body during use, and improving the stability of the elastic compression band in fixing the trachea.

[0027] A car seat, including the aforementioned seat fixing structure.

[0028] In this solution, by setting the aforementioned seat fixing structure on the car seat, the air tube in the airbag system can be conveniently and stably fixed to the felt body at a very low cost. The structure is simple and the air tube is easy to install and fix. During use, the connection between the air tube and the felt body is stable, effectively improving the comfort of driving.

[0034] The following detailed description illustrates the specific implementation method:

[0035] The reference numerals in the accompanying drawings include: 1. Felt body; 2. Control valve; 3. Air pipe; 4. Elastic compression band; 5. Fixing gap; 6. Expansion joint; 7. Reinforcing layer.

[0036] Example 1

[0037] This embodiment is as shown in the appendix. Figure 1 The following describes a seat fixing structure: It includes a felt body 1 and a control valve 2 fixedly connected to one side of the felt body 1 by screws. Multiple air pipes 3 are detachably connected to the control valve 2. In this embodiment, the multiple air pipes 3 are distributed and connected to the left and right sides of the control valve 2. In this embodiment, multiple fixing units are provided on the felt body 1, and at least one fixing unit is provided on both the left and right sides of the control valve 2 to fix all the air pipes 3 on the corresponding sides. Figure 1 The diagram shows a configuration where four air pipes 3 are provided on both the left and right sides of the control valve 2, and a fixed unit is provided on both the left and right sides of the control valve 2. In other embodiments besides this one, the number of air pipes 3 on each side and the number of fixed units on each side can be set according to actual conditions, and will not be illustrated here.

[0038] Combination Figure 1 and Figure 2The fixing unit includes two slits cut into the felt body 1. In this embodiment, the two slits are of equal length and arranged parallel to each other. During use, the felt between the two slits elastically protrudes towards the side of the felt body 1 where the control valve 2 is fixed, forming an elastic compression band 4. After the elastic compression band 4 protrudes from one side of the felt body 1, it forms a fixing gap 5 between itself and the felt body 1 for fixing the air tubes 3. In this example, in order to ensure that the elastic compression band 4 can stably press and fix multiple air tubes 3 on the same side of the control valve 2 against the side of the felt body 1, when setting the fixing gap 5, the width S of the fixing gap 5 is greater than or equal to 10 mm, preferably 12 mm, the thickness of the felt body 1 is greater than or equal to 2 mm, preferably 2.5 mm, and the basis weight of the felt body 1 is in the range of 500-600 g / m², preferably 550 g / m². At the same time, in order to facilitate the arrangement of the air tubes 3, the distance between the fixing unit near the control valve 2 and the control valve 2 is set to be greater than or equal to 20 mm. Figure 1 D ≥ 20mm, preferably 20mm. Furthermore, in this embodiment, when setting the length of the fixed gap 5, the number of air tubes 3 fixed within the fixed gap 5 is N, the diameter of the air tube 3 is φ, and the length of the fixed gap 5 is L, where L ≥ (N+1)*φ. For example, in this embodiment, the number of air tubes 3 is four, and the diameter φ of the air tube 3 is 3mm, then L ≥ (4+1)*4 = 20mm. Specifically, it is set to 35mm, which not only effectively fixes the air tubes 3 but also avoids the elastic compression band 4 being too long and thus having insufficient elastic compression force on the air tubes 3, effectively ensuring the stability of the compression fixation of the air tubes 3.

[0039] In this embodiment, two matching slits are directly cut into the felt body 1 by cutting. Relying on the good elasticity of the felt body 1 itself, the felt part between the two slits can form an elastic compression band 4 for fixing multiple air tubes 3. The slits are easy to process, and the installation and fixing of the air tubes 3 are also very convenient. Compared with the method of fixing the air tubes 3 to the felt body 1 using fixing parts such as clips, the cost is lower, and the installation and fixing of the air tubes 3 is more convenient, efficient and stable.

[0040] A car seat includes the aforementioned seat fixing structure. By setting the aforementioned seat fixing structure inside the car seat, the air pipe 3 can be installed and fixed in a low-cost, efficient and stable manner, effectively ensuring the stability of the massage system inside the seat during use and improving the user's comfort while driving.

[0041] Example 2

[0042] The difference between Example 2 and Example 1 is as follows: Figure 3As shown, in this embodiment, an expansion joint 6 is formed on the elastic compression band 4 along its length. The length of the expansion joint 6 is less than the length of the fixed gap 5. There can be one or more expansion joints 6. When there are multiple expansion joints 6, they are arranged along the width of the fixed gap 5. In this embodiment, by setting the expansion joint 6, the elastic compression band 4 can more easily undergo elastic deformation along its own length, making the installation and fixation of the air tube 3 easier and less strenuous. Furthermore, the structure of the elastic compression band 4 is more stable when it undergoes elastic deformation, effectively improving the stability of the elastic compression of the air tube 3 by the elastic compression band 4.

[0043] Example 3

[0044] The difference between Example 3 and Example 1 is as follows: Figure 4 As shown in this embodiment, in the two parallel cuts in the fixing unit, the length of the cut closer to the control valve 2 is greater than the length of the other cut. When the felt part between the two cuts elastically protrudes to one side of the felt body 1 to form an elastic compression band 4, the fixing gap 5 formed by the elastic compression band 4 has a large opening on the side closer to the control valve 2 and a small opening on the side farther from the control valve 2. When fixing multiple air tubes 3, the multiple air tubes 3 are inserted into the fixing gap 5 from the large opening and then exit from the small opening of the fixing gap 5. The opening of the fixing gap 5 gradually decreases, making it very convenient for the air tubes 3 to enter the fixing gap 5. When exiting the fixing gap 5, the fixing gap 5 can automatically "tighten" the multiple air tubes 3, so that the multiple air tubes 3 can be fixed neatly side by side on the felt body 1.

[0045] Example 4

[0046] The difference between Example 4 and Example 1 is as follows: Figure 5 As shown, in this embodiment, a reinforcing layer 7 is fixedly connected to the felt body 1. The reinforcing layer 7 is located at both ends of the cut and is perpendicular to the elastic extrusion band 4. The two ends of the reinforcing layer 7 protrude from both sides of the elastic extrusion band 4. Specifically, the reinforcing layer 7 can be made of flexible and wear-resistant materials such as non-woven fabric, and then fixed to the side of the felt body 1 by sewing or other means. The reinforcing layer 7 is used to structurally reinforce the position of the felt body 1 at both ends of the elastic extrusion band 4, reducing the risk of tearing and damage to the felt body 1 in this range during use, so that the elastic extrusion band 4 can play a more stable fixing effect on the air tube 3.
