[0030] The following further describes the detailed implementation manners of the present utility model with reference to the accompanying drawings.

[0031] It is easy to understand that according to the technical solution of the present utility model, under the premise of not changing the essence of the present utility model, those of ordinary skill in the art can adopt various structural forms and implementation manners that can be mutually replaced. Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present utility model, and should not be regarded as the whole of the present utility model or as a limitation or restriction on the technical solution of the utility model.

[0032] In this specification, orientation terms such as upper, lower, left, right, front, rear, front side, back side, top, bottom, etc., which are mentioned or may be mentioned, are defined relative to the structures shown in the respective drawings. They are relative concepts and may therefore change accordingly depending on their different positions and usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0033] As Figures 1 to 2 shown, the present application provides an airbag and seat connection assembly, including: a side airbag 1 and a seat frame 3.

[0034] As Figures 3 to 4 shown, an installation opening 30 is formed in the side wall of the seat frame 3. One side of the installation member 2 is used to connect to the side airbag 1. The installation member 2 sequentially includes a clamping groove 20 and a limiting portion 21 in a direction away from the side airbag 1. As Figures 3 to 4 shown, one end of the installation member 2 can be welded, integrally formed or bolted to the side airbag 1. The clamping groove 20 is a U-shaped groove. The limiting portion 21 is cylindrical, and the outer diameter of one end of the limiting portion 21 away from the clamping groove 20 gradually becomes smaller for easy installation. The side airbag 1 in the embodiment of the present application can include either an outer airbag or an inner airbag.

[0035] As Figures 5 to 7 shown, a clamping elastic piece 4 is arranged inside the side wall of the seat frame 3. The clamping elastic piece 4 is opposite to the installation opening 30, and a clamping angle 40 extending in a direction close to the installation opening 30 is provided on the clamping elastic piece 4. The side wall of the seat frame 3 is located on the frame or other rigid structure of the seat frame 3. The clamping elastic piece 4 can be a metal elastic piece or a plastic elastic piece.

[0036] The side airbag 1 is attached to the side wall. The limiting portion 21 passes through the installation opening 30 and abuts against one side of the clamping elastic piece 4 facing the installation opening 30. The clamping angle 40 and the side wall of the installation opening 30 respectively abut against the clamping groove 20 along the circumferential direction of the clamping groove 20.

[0037] For the airbag and seat connection assembly provided by the embodiment of the present application, during installation, the installation member 2 of the side airbag 1 is pressed into the installation opening 30. The clamping elastic piece 4 is pushed up by the limiting portion 21, and the clamping angle 40 is clamped at the opening of the U-shaped clamping groove 20. The remaining part of the clamping groove 20 along the circumferential direction abuts against the side wall of the installation opening 30 entirely or partially, making a "click" sound of falling into place. This falling-in-place sound indicates that the side airbag 1 is reliably connected to the seat frame 3.

[0038] The airbag and seat connection component provided by this application has a mounting part 2 on the side airbag 1, which is provided with a clamping groove 20 and a limiting part 21. The limiting part 21 extends into the mounting opening 30 of the seat frame 3. The clamping corner 40 of the clamping spring piece 4 in the seat frame 3 and the side wall of the mounting opening 30 are abutted against the clamping groove 20 along the circumferential direction of the clamping groove 20 to position the mounting part 2 along the circumferential direction of the mounting part 2. One side of the limiting part 21 in the axial direction abuts against the part of the clamping spring piece 4 facing the mounting opening 30, and the clamping corner 40 abuts against the other side of the limiting part 21 facing away from the clamping spring piece 4. The other side of the limiting part 21 in the axial direction is limited by the clamping corner 40 clamped in the clamping groove 20 to position the mounting part 2 along the axial direction of the mounting part 2. The above clamping installation method does not require installation tools and tool space, is fast and convenient, can be completed by a single person, shortens the installation time, reduces the installation space, avoids waste of the space of the seat frame 3, and moreover, if the mounting part 2 fails to be fully inserted, it will be ejected by the clamping spring piece 4, avoiding the possibility of false locking. The clamping structure is stable and reliable, ensuring the long-term stability and reliability of the connection.

[0039] As an optional embodiment, the clamping spring piece 4 includes a mounting part 41, a clamping part 42 and a buckling part 43 arranged in sequence; the mounting part 41 is mounted on the side wall; the clamping part 42 extends away from the side wall and is provided with the clamping corner 40; the buckling part 43 abuts against the limiting part 21. Please refer to Figures 5 to 7 , the mounting part 41 is a sheet-like structure and is fixedly attached to the side wall by two rivets 5, which is stable and reliable. The clamping corner 40 on the clamping part 42 is partially embedded in the clamping groove 20 to apply force to the mounting part 2 along the circumferential direction, and the buckling part 43 abuts against the end face of the limiting part 21 to apply force to the mounting part 2 along the axial direction.

[0040] As an optional embodiment, the mounting part 41 is located on one side of the mounting opening 30. The mounting opening 30 is a strip-shaped opening and extends in a direction away from the mounting part 41. The width of the strip-shaped opening gradually becomes smaller in a direction away from the mounting part 41. During installation, the mounting part 2 is inserted into the strip-shaped opening from the side with a larger inner diameter of the strip-shaped opening, and then slides in a direction away from the mounting part 41 until the clamping groove 20 abuts against the end with a smaller inner diameter of the strip-shaped opening. At this time, the side wall of the strip-shaped opening simultaneously abuts against the clamping groove 20 to limit the bottom and side of the clamping groove 20. At this time, the clamping corner 40 is clamped into the top of the clamping groove 20 to limit the top of the clamping groove 20, which is stable and reliable.

[0041] As an alternative embodiment, the snap-in portion 42 includes an inclined section 420 and a mounting section 421 connected to each other. The inclined section 420 is connected to the mounting portion 41 and extends away from the side wall. The snap angle 40 is provided on the mounting section 421. An avoidance opening 422 for avoiding the limiting portion 21 is formed in the inclined section 420, and the inner diameter of the avoidance opening 422 is larger than the outer diameter of the limiting portion 21. In the embodiment of the present application, the inclined section 420 functions to avoid the mounting member 2, and the avoidance opening 422 prevents the inclined section 420 from interfering with the position of the mounting member 2, while saving materials. The inclination angle of the mounting section 421 is smaller than that of the inclined section 420. The mounting section 421 supports the snap angle 40 to ensure stable snap connection between the snap angle 40 and the snap-in groove 20.

[0042] As an alternative embodiment, the snap angle 40 includes an extension section 400 and a snap-in section 401 that are bent and connected. The extension section 400 is mounted on the mounting section 421 and extends away from the inclined section 420. The snap-in section 401 snaps into the snap-in groove 20. The extension section 400 provides a space for the elastic deformation of the snap angle 40, and the snap-in section 401 is bent and then snaps into the snap-in groove 20.

[0043] As an alternative embodiment, an elastic abutting portion is provided on the inner wall of the snap-in groove 20, and the end of the snap-in section 401 abuts against the abutting portion. The abutting portion in the embodiment of the present application can be rubber, plastic or a spring piece provided on the inner wall of the snap-in groove 20. When the snap-in section 401 is snapped into the snap-in groove 20, it abuts against the elastic abutting portion to eliminate possible vibration noise.

[0044] As an alternative embodiment, the fastening portion 43 is bent to define a bending area 430, and the bending area 430 has a smooth transition and abuts against the limiting portion 21. As Figures 5 to 7 shown, the bending area 430 generates a pressure towards the mounting member 2 due to the bending, so that when the bending area 430 abuts against the end face of the limiting portion 21, it also plays a pressing role on the limiting portion 21 to effectively limit the mounting member 2 axially along the mounting member 2.

[0045] As an alternative embodiment, the number of the mounting members 2 is at least two, and at least two of the mounting members 2 are arranged along the length direction of the side airbag 1; mounting openings 30 corresponding to at least two of the mounting members 2 are formed on the side wall, and snap-in elastic pieces 4 corresponding to at least two of the mounting members 2 are provided. As Figures 3 to 6 shown, two mounting members 2 can effectively increase the connection stability between the side airbag 1 and the seat frame 3.

[0046] The present application also provides a seat assembly, including the airbag and seat connection component according to any one of the above embodiments, and the side airbag 1 is installed on the seat frame.

[0047] The present application also provides a vehicle, including the seat assembly according to the above embodiments.

[0048] According to requirements, the above technical solutions can be combined to achieve the best technical effects.

[0049] The above are only the principles and preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, based on the principles of the present utility model, several other variations can also be made, which should also be regarded as the protection scope of the present utility model.
