Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to an airbag for shoulder adjustment and an automotive seat. Background Technology

[0002] With the development of intelligent and multifunctional vehicles, users have increasingly higher requirements for car seats. Some car seats are equipped with airbags near the passenger's shoulders for shoulder adjustment. By inflating the airbags, the passenger's shoulders can be supported to improve passenger comfort.

[0003] In existing car seats, the airbags used for shoulder adjustment are generally designed in a circular or rectangular shape. These airbags are not designed according to the human body structure, resulting in insufficient support for passengers after inflation. Furthermore, the airbags are usually placed on the front of the foam and the inside of the seat cover, resulting in a small contact area with the body during shoulder adjustment, which can easily cause passengers to feel a foreign object sensation and lead to poor comfort. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose an airbag and car seat for shoulder adjustment that is optimized according to human body structure and ensures passenger comfort.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose an air bag for shoulder adjustment, comprising:

[0006] The air bag body has an inflation chamber, and the air bag body is equipped with a large end and a small end that are arranged opposite to each other;

[0007] A fixing edge is provided on one side of the air bag body. By fixing the fixing edge to the car seat, the air bag can be installed on the car seat.

[0008] When the inflation chamber is filled with air, the small end can support the inner side of the passenger's shoulder, and the large end can support the outer side of the passenger's shoulder.

[0009] Furthermore, after the gas in the inflation chamber is released, the main body of the air bag is arranged in a cam shape.

[0010] Furthermore, the smaller end has a first arc-shaped edge, the larger end has a second arc-shaped edge, and the radius of the second arc-shaped edge is greater than the radius of the first arc-shaped edge.

[0011] Furthermore, after the inflation chamber is filled with air, the expansion support lifting stroke of the large end of the air bag body is greater than that of the small end.

[0012] Furthermore, after the fixed edge is fixed to the car seat, air is inflated into the inflation chamber, and the air bag body is fixed on one side by the fixed edge, expanding and lifting up.

[0013] Furthermore, there are two air bag bodies, and the two air bag bodies are stacked on top of each other;

[0014] Both airbag bodies can be fixed to the car seat via the fixed edge, and when inflating the air chambers of the two airbag bodies, both airbag bodies are fixed on one side of the fixed edge and expand and rise.

[0015] Furthermore, the expansion support lifting stroke of the two air bag bodies is greater than or equal to 50 mm.

[0016] Furthermore, the air bag body is fixed on one side by the fixed edge, and after expansion and lifting, the side of the air bag body opposite to the fixed edge forms a fan shape.

[0017] Furthermore, an air tube is connected to the main body of the air bag, through which the air bag is inflated or deflated.

[0018] This utility model also proposes a car seat, wherein the above-mentioned air bags for shoulder adjustment are symmetrically arranged on the back of the car seat, and the small end of the air bag is disposed near the inner side of the back of the seat, and the large end of the air bag is disposed near the outer side of the back of the seat.

[0019] The fixed edge is fixed to the backrest by a fastener;

[0020] Furthermore, the air bag is located on the back side of the foam of the backrest.

[0021] Compared with the prior art, the present invention has at least the following beneficial effects:

[0022] In this invention, the airbag body is configured with a large end and a small end, i.e., it is cam-shaped. After the air chamber is filled with air, the small end can support the inner side of the passenger's shoulder, and the large end can support the outer side of the passenger's shoulder. The optimized configuration according to the human body structure can ensure a better wrapping feeling and a better fit to the passenger's shoulder, thereby improving the passenger's riding comfort.

[0023] In this invention, after the air chamber of the air bag body is filled with air, the expansion support at the larger end has a greater lifting stroke than the expansion support at the smaller end, which better conforms to the contour of the human shoulder.

[0024] In this invention, the main body of the air bag is fixed to the car seat on one side by a fixed edge. After inflation, it is fixed on one side by the fixed edge and expands and lifts up. After inflation, its opposite side is fan-shaped. The inflation amount can be controlled to meet the needs of passengers of different sizes, both small and large.

[0025] In this invention, the air bag is set on the back side of the foam backrest, and when the air bag is raised, the foam and the cover can fit the shape of the passenger's shoulder better, resulting in a good fit, less foreign body sensation, and better passenger comfort.

[0039] Example 1:

[0040] like Figures 1-5 As shown, an airbag for shoulder adjustment according to this embodiment includes: an airbag body 100 and a fixing edge 200 disposed on the airbag body 100. The airbag body 100 has an inflation chamber, and is equipped with a large end 11 and a small end 12 arranged opposite to each other. When the inflation chamber is full of air, the large end 11 and the small end 12 are lifted up. The fixing edge 200 is disposed on one side of the airbag body 100. By fixing the fixing edge 200 to the car seat, the airbag can be installed on the car seat. That is, the airbag in this embodiment is fixed to the car seat on one side by the fixing edge 200, and the expansion of other parts is unrestricted. The fixing member is preferably a Christmas tree clip. At least two through holes 20 are provided on the fixing edge 20. The fixing member passes through the through holes 20 to fix the fixing edge 200 to the car seat. The fixing edge 200 is easily installed and removed by the Christmas tree clip. Of course, it can also be fixed by means similar to fixing bolts or screws, but compared to that, the Christmas tree clip-on fixing method is simpler and more convenient. An air tube is connected to the air bag body 100, and the air bag body 100 is inflated and deflated through the air tube. That is, a single air tube can serve as both the air inlet and outlet of the air bag body 100, making it easy to control.

[0041] In actual use, when the inflation chamber is filled with air, the small end 12 can support the inner side of the passenger's shoulder, and the large end 11 can support the outer side of the passenger's shoulder.

[0042] To explain, in this embodiment, when the gas in the inflation chamber of the airbag is released (i.e., in the deflated state), the airbag body 100 is cam-shaped, and the airbag as a whole is flattened and placed in the car seat. In the deflated state, the small end 12 has a first arc-shaped edge 12A, and the large end 11 has a second arc-shaped edge 11A, with the radius of the second arc-shaped edge 11A being larger than the radius of the first arc-shaped edge 12A. This ensures that after the airbag inflates, the volume of the large end 11 is greater than the volume of the small end 12. To further explain, the large end 11 and the small end 12 are compared; when deflated, the radius of the large end 11 is greater than the radius of the small end 12, and after inflating, the volume of the large end 11 is greater than the volume of the small end 12.

[0043] In actual use, the airbag body 100 of this embodiment is equipped with a large end 11 and a small end 12, which are arranged in a cam shape. After the air chamber is filled with air, the small end 12 can support the inner side of the passenger's shoulder, and the large end 11 can support the outer side of the passenger's shoulder. The optimized setting according to the human body structure can ensure a better wrapping feeling and a better fit with the passenger's shoulder, thereby improving the passenger's riding comfort.

[0044] Furthermore, when the inflation chamber is filled with air, the expansion support lifting stroke of the large end 11 of the airbag body 100 is greater than that of the small end 12, making the airbag design more in line with the human body's structure and the contour of the human shoulder. In a relaxed state, the human shoulder generally slopes downwards from the inside to the outside, with the inner part of the shoulder further back and the outer part further forward. Additionally, the outer surface area of ​​the human shoulder is larger than the inner surface area. Therefore, the airbag shape in this embodiment is designed to mimic the human body's structure, resulting in better shoulder support and improved passenger comfort.

[0045] In this embodiment, after the fixed edge 200 on the airbag is fixed to the car seat, air is inflated into the inflation chamber of the airbag body 100. The airbag body 100 is fixed on one side with the fixed edge 200, and expands upwards. Since one side of the airbag body 100 is fixed and the other parts are in a free state, when fully inflated, the airbag body 100 is fixed on one side with the fixed edge 200, expands upwards, and the other parts expand. After the airbag body 100 is fixed on one side with the fixed edge 200 and expands upwards, the side of the airbag body 100 opposite to the fixed edge 200 forms a fan shape, ensuring good support and simultaneously accommodating both large and small passengers, increasing the feeling of being enveloped by the car seat and the passenger's shoulders. For large passengers, a small amount of air can be inflated, and more air can be added. For small passengers, a large amount of air can be inflated, and less air can be added.

[0046] As a preferred embodiment, this embodiment provides two airbag bodies 100, which are stacked. Both airbag bodies 100 can be fixed to the car seat via the fixing edge 200. When inflating the inflation chambers of the two airbag bodies 100, both airbag bodies 100 are fixed on one side of the fixing edge 200, expanding and lifting. That is, the fixing edge 200 of the two stacked airbag bodies 100 is fixed on one side, and the other side expands and lifts simultaneously during inflation. The two airbag bodies 100 unfold in a hinge-like shape. At this time, the fixing edge 200 is equivalent to the rotation center axis of the two airbag bodies 100, and the two airbag bodies 100 are equivalent to the two hinge pieces of a hinge. The expansion support lifting stroke of the two airbag bodies 100 is greater than or equal to 50 mm, resulting in high lifting efficiency and a large lifting stroke. The design of the double airbag bodies 100 can support a load of up to 21 kg.

[0047] In actual use, the airbag body 100 in this embodiment is fixed to the car seat on one side by the fixed edge 200. After the airbag body 100 is inflated, the airbag is fixed on one side by the fixed edge 200 and expands. After inflation, its opposite side is fan-shaped. The inflation amount can be controlled to meet the needs of passengers of different sizes, both small and large.

[0048] Example 2:

[0049] like Figure 3 and Figure 5 As shown, in this embodiment of a car seat, airbags for shoulder adjustment as described in Embodiment 1 are symmetrically arranged on the backrest of the car seat. The small end 12 of the airbag is located near the inner side of the backrest, and the large end 11 of the airbag is located near the outer side of the backrest. The fixing edge 200 of the airbag is fixed to the backrest by a fastener to install the airbag on the car seat, and the airbag is located on the back side of the foam of the backrest.

[0050] In existing car seats equipped with shoulder massage functions, the shoulder massage airbags are placed on the A-side (front) of the foam backrest. When the airbags are inflated, they directly lift the seat cover and support the passenger's shoulders, causing a noticeable foreign body sensation. When applied to shoulder adjustment, this noticeable foreign body sensation causes significant discomfort and reduces passenger comfort.

[0051] In contrast, the shoulder adjustment airbag in this embodiment is located on the back side of the backrest foam. When the airbag is raised, it lifts the backrest foam and then acts on the passenger's shoulder, which makes the foam and cover fit the shape of the passenger's shoulder better, resulting in a better fit, less foreign body sensation, and better passenger comfort.

[0052] In this design, the airbags used for shoulder adjustment are optimized according to human anatomy, which can enhance the seat's wrapping effect on the passenger's shoulders, reduce the feeling of foreign objects when fully inflated, and provide a better fit to the passenger's shoulders, thereby effectively ensuring passenger comfort.
