[0023] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0024] It is easy to understand that according to the technical solution of the present invention, a variety of structural modes and implementation modes can be replaced with each other by those skilled in the art without changing the essential spirit of the present invention. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the invention.

[0025] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to the structure shown in the drawings. They are relative concepts and may vary depending on the location and usage of the device. Therefore, these or other directional terms should not be interpreted as restrictive.

[0026] In some embodiments of the present invention, as shown in Figures 1-3, the side airbag is located between adjacent seats after deployment, and the side airbag includes a first air chamber 1, a second air chamber 2 and a third air chamber 3. The first air chamber 1 is located between the second air chamber 2 and the third air chamber 3. The second air chamber 2 is deployed toward one of the adjacent seats, and the third air chamber 3 is deployed toward the other adjacent seat. The first air chamber 1 includes a main air chamber 11 and a secondary air chamber 12. The main air chamber 11 is deployed toward the front of the seat, and the secondary air chamber 12 is deployed toward the upper rear of the seat.

[0027] Specifically, as shown in Figure 1, the front row of the vehicle includes a driver's seat 10 and a passenger seat 20. After deployment, the side airbag is positioned between the driver's seat 10 and the passenger seat 20. The second chamber 2 deploys toward the driver's seat 10, protecting the occupant of the driver's seat 10. The third chamber 3 deploys toward the passenger seat 20, contacting it or the occupant of the passenger seat 20. This provides support for the first and second chambers 1 and 2, enhancing the stability of the deployed side airbag.

[0028] As shown in FIG2 , the first air chamber 1 includes a main air chamber 11 and a secondary air chamber 12 . The main air chamber 11 and the secondary air chamber 12 are integrally formed, wherein the main air chamber 11 is deployed toward the front of the seat. When the seat is in normal use, the main air chamber 11 plays a protective role for the occupant.

[0029] As shown in FIG3 , the auxiliary air chamber 12 is deployed toward the rear of the seat. When the seat slides rearward, the occupant is staggered from the main air chamber 11 and corresponds to the auxiliary air chamber 12 , thereby protecting the occupant.

[0030] In this embodiment, the first air chamber 1 is configured as a main air chamber 11 extending forward and a secondary air chamber 12 extending backward, thereby increasing the coverage of the first air chamber 1. When the seat is adjusted forward and backward along the slide rail, the occupant can be protected.

[0031] Furthermore, as shown in FIG. 2 , the main air chamber 11 is connected to the second air chamber 2 through the first air hole 21 , and the main air chamber 11 is connected to the third air chamber 3 through the second air hole 31 .

[0032] In this embodiment, there are two first air holes 21 , connecting the main air chamber 11 and the second air chamber 2 ; there are also two second air holes 31 , connecting the main air chamber 11 and the third air chamber 3 .

[0033] Optionally, the number of the first air hole 21 and the second air hole 31 can also be one, or more than two.

[0034] Furthermore, the main air chamber 11 is directly connected to the inflator. During inflation, the first air chamber 1 is first deployed, and then the second air chamber 2 and the third air chamber 3 are deployed simultaneously.

[0035] Optionally, the inflator may also be directly connected to the second air chamber 2 or the third air chamber.

[0036] Furthermore, as shown in FIG2-3 , the main air chamber 11 at least corresponds to the torso of the occupant after it is deployed, and the height of the auxiliary air chamber 12 after it is deployed corresponds to the head of the occupant.

[0037] In this embodiment, the main air chamber 11 is deployed toward the front of the seat, corresponding to the position of part of the occupant's head, upper body and part of the legs, thereby protecting the occupant's torso.

[0038] Preferably, the main air chamber 11 can also correspond to the positions of the entire head and thighs of the occupant.

[0039] As shown in FIG2 , when the seat slides forward, the auxiliary air chamber 12 is located behind the occupant's head;

[0040] As shown in FIG3 , when the seat slides backward, the auxiliary air chamber 12 corresponds to the head of the occupant and can protect the head of the occupant.

[0041] Preferably, after the auxiliary air chamber 12 is deployed, it can also correspond to the head and torso of the occupant, thereby providing better protection for the occupant.

[0042] Furthermore, as shown in FIG2 , a first non-inflated area 13 is provided in the main air chamber 11 . The first non-inflated area 13 is used to control the thickness of the main air chamber 11 to ensure the stability of the total volume.

[0043] Furthermore, as shown in FIG2 , a second non-inflated area 14 is provided in the auxiliary air chamber 12 . The second non-inflated area 14 is used to control the thickness of the auxiliary air chamber 12 to ensure the stability of the total volume.

[0044] Since the volume of the main air chamber 11 and the auxiliary air chamber 12 after expansion is large, in order to increase the stability after expansion, a non-inflation area is added to the main air chamber 11 and the auxiliary air chamber 12. The non-inflation area is a closed area sewn in the air chamber by sewing thread, and air cannot be inflated in this area.

[0045] Furthermore, as shown in FIG1 , after the second air chamber 2 is deployed, it corresponds to at least the shoulder and arm of the occupant, and the second air chamber 2 can protect the shoulder and arm of the occupant on the driver's seat 10 .

[0046] Optionally, after being unfolded, the second air chamber 2 can also contact the side of the main frame seat 10, thereby supporting the first air chamber 1.

[0047] Furthermore, as shown in FIG1 , the third air chamber 3 contacts the seat after being unfolded. The third air chamber 3 is located on the lower side of the first air chamber 1 , and contacts the side of the passenger seat 20 after being unfolded, thereby supporting the first air chamber 1 and the second air chamber 2 .

[0048] Optionally, the third air chamber 3 may also be in contact with the occupant of the passenger seat 20 , thereby providing support on the one hand and protecting the occupant of the passenger seat 20 on the other hand.

[0049] In this embodiment, the volume of the first air chamber 1 is greater than the volumes of the second air chamber 2 and the third air chamber 3 .

[0050] In another embodiment of the present invention, as shown in Figures 1-3, the seat includes the side airbag of any of the above embodiments, and the side airbag is folded in the foam layer of the seat before inflation. A slide rail (not shown) is provided at the bottom of the seat. When the seat slides to the front end of the slide rail, the occupant on the seat corresponds to the main air chamber 11. When the seat slides to the rear end of the slide rail, the occupant on the seat corresponds to the auxiliary air chamber 12.

[0051] Specifically, as shown in FIG2 , when the seat is in normal use or slides to the front end of the slide rail, the main air chamber 11 corresponds to the occupant to protect the occupant.

[0052] As shown in FIG3 , when the seat slides backward to the rearmost end of the slide rail, the occupant is offset from the main air chamber 11 , and the auxiliary air chamber 12 corresponds to the occupant to protect the occupant.

[0053] This embodiment is applicable to seats with long slide rails and can protect passengers no matter how the seat slides.

[0054] The above description is only the principle and preferred embodiment of the present invention. It should be noted that for those skilled in the art, several other variations can be made based on the principle of the present invention, which should also be considered as the scope of protection of the present invention.
