[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0043] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] Currently, as users' demands for automotive comfort increase, car seats are becoming more and more functional, and the space inside the seats is being taken up by more and more devices. Therefore, in order to prevent the seats from taking up extra space, the foam padding is being designed to be thinner and thinner.

[0045] Massage airbags are usually fixed to foam pads with straps. Not only is it easy to damage the foam when fixing them, but when the massage airbag is working, it will also constantly rise and fall, pulling the foam forward with the straps, which can easily tear the foam.

[0046] To avoid this situation, the present invention provides an assembly structure for a massage system for automobile seats.

[0047] Example 1

[0048] Please refer to Figure 1-5 The car seat has a support surface for supporting a human body, the car seat includes a foam 1, the foam 1 has a first connecting hole 3, and the assembly structure includes;

[0049] A ventilation assembly is installed on the side of the foam 1 away from the bearing surface;

[0050] The ventilation component includes a ventilation bag 2, and the ventilation bag 2 has a second connection hole 4.

[0051] A massage component is disposed on the side of the foam 1 near the bearing surface, passes through the first connecting hole 3 and the second connecting hole 4, and abuts against the surface of the ventilation bag 2 away from the foam 1.

[0052] Specifically, the ventilation component and the massage component are respectively located on both sides of the car seat foam 1; the massage component passes through the first connecting hole 3 and the second connecting hole 4 and abuts against the ventilation air bag 2. This allows the foam 1, ventilation component, and massage component to be firmly bound together, achieving a stable fixation of their relative positions. In this configuration, the ventilation component provides further support to the massage component at weak points in the foam 1, preventing the foam 1 from tearing and the massage component from detaching, thus extending its service life.

[0053] Furthermore, the massage component includes:

[0054] A pull strap 6, one end of which passes through the first connecting hole 3 and the second connecting hole 4 and is fixedly connected to the limiting component; the other end of the pull strap 6 is fixedly connected to the foam 1, or passes through another first connecting hole 3 and another second connecting hole 4 and is fixedly connected to another limiting component.

[0055] Massage air bag 5, wherein the massage air bag 5 is disposed on the side of the foam 1 near the bearing surface and is fixedly connected to the surface of the pull strap 6 near the bearing surface;

[0056] A limiting component is provided on the side of the foam 1 away from the bearing surface and is fixedly connected to both ends of the pull strap 6 respectively; at least one of the limiting components is used to abut against the ventilation air bag 2 to fix the relative positions between the pull strap 6, the massage air bag 5, the foam 1 and the ventilation air bag 2.

[0057] Specifically, multiple massage air bags 5 are sequentially connected to the pull strap 6. When the two ends of the pull strap 6 are connected to the limiting component, the pull strap 6 is tightened, thereby fixing the relative positions of the multiple massage air bags 5 and the foam 1.

[0058] Moreover, the ventilation bag 2 is usually made of TPU film and non-woven fabric sealed and welded together, and fixed to the seat foam by means of adhesive or other methods. It is equipped with an air guide layer for guiding airflow. The air guide layer is usually made of three-dimensional knitted mesh fabric. The three-dimensional knitted mesh fabric has a certain thickness and flexibility, and has good elasticity and support.

[0059] In this situation, when the massage component needs to be fixed in a relatively thin part of the foam, the pull strap 6 can pass through the first connecting hole 3 on the foam 1 and the second connecting hole 4 on the ventilation bag 2 in sequence, and then the limiting component abuts against the ventilation bag 2. At this time, the three-dimensional knitted mesh fabric inside the ventilation bag 2 can provide a certain support for the massage component, making the foam 1 less prone to tearing, making the massage component more secure, less likely to fall off, and extending the life of the seat foam.

[0060] The ventilation bag 2 has a fan connection hole 16 on the side away from the foam 1 for connecting the fan 15, and multiple air distribution holes 17 on the side closer to the foam. Ventilation holes 18 corresponding to the air distribution holes 17 are provided through the foam. The airflow is blown out by the fan 15 and blown to the side of the seat in sequence through the air guide layer, the air distribution holes 17 and the ventilation holes 18, or it is drawn into the fan 15 in sequence through the ventilation holes 18, the air distribution holes 17 and the air guide layer. Therefore, although opening a second connection hole on the ventilation bag 2 can increase the support for the massage component, it will cause the airflow of the fan 15 to leak from the second connection hole, affecting the ventilation effect. Therefore, a certain sealing structure should be set on the limiting component passing through the second connection hole to prevent airflow leakage at this point.

[0061] Specifically, in the first implementation, refer to Figure 6 The limiting component that abuts against the ventilation bag 2 includes:

[0062] A sealing layer 7 is disposed on the side of the first fixing plate 9 near the foam 1; a third connecting hole 8 is provided on the sealing layer 7;

[0063] The first fixing plate 9 is disposed on the side of the sealing layer 7 away from the ventilation bag 2, and passes through the third connecting hole 8 to be fixedly connected to the pull strap 6.

[0064] Specifically, the sealing layer 7 is in close contact with the ventilation bag 2, increasing the area of ​​interaction between them and preventing excessive force on a single point, which could cause the entire foam 1 to tear. The sealing layer 7 also prevents gas from moving through the first connecting hole 3 and the second connecting hole 4 to the side of the foam 1 away from the passenger, thus preventing air leakage.

[0065] In the second implementation method, refer to Figure 7 The limiting component includes:

[0066] The second fixing plate 10 is disposed on the side of the ventilation bag 2 away from the foam 1 and is fixedly connected to the pull strap 6;

[0067] The second fixing plate 10 has a first sealing protrusion 11 on the side near the ventilation bag 2; the first sealing protrusion 11 is used to tightly abut against the ventilation bag 2.

[0068] Furthermore, the first sealing protrusion 11 is annular; the second fixing plate 10 is located on the inner side of the first sealing protrusion 11, opposite to the second connecting hole 4, to prevent gas from moving from the ventilation bag 2 away from the passenger side via the limiting component.

[0069] Specifically, there may still be air leakage at the third connecting hole 8 of the first fixing plate 9. Therefore, in the above-described method, the first sealing protrusion 11 on the second fixing plate 10 is tightly abutted against the ventilation bag 2. Since there are no additional openings on the second fixing plate 10, there is no air leakage after the annular first sealing protrusion 11 abuts against the ventilation bag 2.

[0070] To avoid excessive force during contact between the first sealing protrusion 11 and the ventilation bag 2, this embodiment also includes the following design:

[0071] Furthermore, the second fixing plate 10 also has an annular second sealing protrusion 12; the first sealing protrusion 11 is located inside the second sealing protrusion 12.

[0072] The multi-protrusion structure design can increase the contact area while ensuring a seal, reduce the stress on the surface of the ventilation bag 2, and also ensure that the foam 1 is not torn.

[0073] In some cases, the seat back also has other structures. In both of the above embodiments, the mounting plates are flat plates, and there are gaps between the edges of the plates and the ventilation airbags 2. To avoid movement interference between the mounting plates and other objects, a third embodiment is also provided:

[0074] Further, refer to Figure 8 The limiting component that abuts against the ventilation bag 2 includes:

[0075] The third fixing plate 13 is disposed on the side of the ventilation bag 2 away from the foam 1 and is fixedly connected to the pull strap 6;

[0076] The third fixing plate 13 has a spherical shell structure, and the edge of the third fixing plate 13 is in close contact with the ventilation bag 2; the protruding part of the spherical shell structure of the third fixing plate 13 faces away from the ventilation bag 2.

[0077] In this embodiment, the use of a spherical shell-shaped third fixing plate 13 makes the shape of the seat back more regular and prevents interference with other objects. Simultaneously, the edge of the third fixing plate 13 tightly abuts against the ventilation air bag 2, maintaining a sealing effect. Furthermore, when the massage air bag is in operation, the center of the third fixing plate 13 is pulled by the strap, causing a certain deformation due to its spherical shell structure, and its edges expand outwards, further improving the sealing effect.

[0078] Furthermore, generally only the end of the pull strap located at a weak point in the foam needs to pass through the ventilation bag 2. In areas with thicker foam, it can pass directly through the foam and be fixed by the limiting component, without the need for an additional sealing structure, thus reducing costs. Figure 6-8 In the middle, the pull strap is located at one end of the upper side of the foam, and the corresponding limiting component. Of course, whether one end passes through the ventilation bag 2 or both ends pass through the ventilation bag 2 can be set according to the actual situation, and no special limitation is made here.

[0079] Furthermore, it also includes:

[0080] A mesh spring 14 is disposed on the side of the ventilation bag 2 away from the foam 1 and is connected to the foam 1 to support the foam 1.

[0081] The spring 14 has multiple support structures, which, when connected to the foam 1 and the ventilation component 2, can stably support the foam 1 and the ventilation bag 2.

[0082] In some embodiments, the first fixing plate 9, the second fixing plate 10, and the third fixing plate 13 are made of rubber, plastic, felt, or sponge. They are sealed to the ventilation bag 2 by tape or by compression.

[0083] Example 2

[0084] This utility model also provides a car seat, which has a support surface for supporting a human body, including:

[0085] Foam 1, wherein a first connecting hole 3 is provided on foam 1, and foam 1 has a bearing surface for supporting the human body;

[0086] It also includes a massage system assembly structure for a car seat as described in any of the above embodiments.

[0087] Specifically, by applying the foam 1 and corresponding assembly structure described in Example 1 to the car seat, the relative positions of the massage component, foam 1, and ventilation component can be stably fixed. In this case, foam 1 is not easily torn, and the massage component is not easily detached, exhibiting high structural stability. Consequently, it is not easily damaged under various usage conditions, thus improving its service life.
