Abstract

This invention discloses a child safety seat, including a seat body and an airbag assembly disposed on the seat body. The seat body includes a seat and a backrest, forming a support space between them. The airbag assembly includes an airbag body in both folded and inflated states. In the folded state, the airbag body is located on the left and right sides of the support space. In the inflated state, the airbag body unfolds towards the center of the support space, so that at least a portion of the airbag body is located directly in front of the backrest and vertically above the seat and below the top edge of the backrest. When folded, the airbag body of this child safety seat is located on the left and right sides of the support space, ensuring that the airbag assembly's placement does not affect passenger comfort. In the event of a car collision, the airbag body inflates to support the occupant's head, while simultaneously preventing the occupant's entire body from moving forward, thus avoiding injury from a strong impact.

Description

Technical Field

[0001] This invention relates to the field of children's products technology, specifically to a child safety seat. Background Technology

[0002] Child safety seats effectively protect children while traveling in a car and are an essential device for families with children. Some child safety seats are equipped with airbags, which consist of an airbag body that can be folded or inflated. When the car is moving normally, the airbag is folded. In the event of a collision, the airbag inflates and blocks the front of the child's body to support them and reduce the impact load. To ensure the airbag effectively blocks the front of the child's body after inflation, current technology typically places the airbag device in the seatbelt buckle, which inevitably increases the buckle's structural volume. When a child is seated in a child safety seat and restrained by the seatbelt, the buckle fits tightly against the child's body; an increased buckle volume would affect the comfort of the ride. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a child safety seat that does not compromise riding comfort.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A child safety seat, comprising: The seat body includes a seat and a backrest disposed on the seat, with a carrying space for sitting formed between the seat and the backrest; An airbag assembly is disposed on the seat body, the airbag assembly including an airbag body having a folded state and an inflated state; When folded, the airbag body is located on the left and right sides of the carrying space; When inflated, the airbag body unfolds toward the center of the support space, such that at least a portion of the airbag body is located directly in front of the backrest and above the seat and below the top edge of the backrest in the vertical direction.

[0005] In some embodiments, the seat body further includes a headrest disposed on the backrest, wherein when the airbag body is inflated, the airbag body is located below the headrest in the vertical direction.

[0006] In some embodiments, the seat body further includes side protection components respectively disposed on the left and right sides of the carrying space, and the airbag components are respectively disposed on the side protection components on each side.

[0007] In some embodiments, when the airbag body is inflated, a pair of airbag bodies on the left and right sides come into contact to form mutual restraint.

[0008] In some embodiments, when the airbag body is in an inflated state, a pair of airbag bodies on the left and right sides abut against each other in the left-right direction; Alternatively, the airbag bodies on the left and right sides are stacked on top of each other in the vertical direction; Alternatively, the airbag bodies on the left and right sides can be stacked on top of each other in the front-to-back direction.

[0009] In some embodiments, when the airbag body is in an inflated state, the ends of the airbag bodies on the left and right sides are spaced apart in the left-right direction.

[0010] In some embodiments, the airbag assembly further includes a constraint structure connected to the airbag body to constrain the position of the airbag body in the inflated state.

[0011] In some embodiments, the restraint structure includes a pull cord connecting the side protection assembly and the airbag body, the pull cord being taut when the airbag body is inflated; Alternatively, the constraint structure may include pull cords at both ends connected to the airbag body, which are tensioned when the airbag body is inflated.

[0012] In some embodiments, when the airbag body is in an inflated state, the airbag body includes a first airbag portion and a second airbag portion, the first airbag portion having a greater thickness in the left-right direction than the second airbag portion, and the second airbag portion extending vertically and close to the side protection component.

[0013] In some embodiments, when the airbag body is in an inflated state, the first airbag portions on the left and right sides abut against each other in the left-right direction. Alternatively, the first airbag portions on the left and right sides have a gap between their ends in the left-right direction; Alternatively, the first airbags on the left and right sides are stacked on top of each other in the vertical direction; Alternatively, the first airbag sections on the left and right sides are stacked on top of each other in the front-to-back direction.

[0014] In some embodiments, the side protection assembly includes a side wing and a fabric cover disposed on the side wing, the side wing being made of a rigid material, and the airbag assembly being covered within the fabric cover.

[0015] In some embodiments, when the airbag body is in a folded state, the airbag body is disposed inside the fabric cover itself; Alternatively, the airbag body is disposed between the side wing and the fabric cover, and the airbag body is fixed to the side wing or the fabric cover; Alternatively, the side wing is provided with a receiving groove, the airbag body is disposed in the receiving groove, and the receiving groove has an outlet for the airbag body to exit the receiving groove.

[0016] In some embodiments, when the airbag body is in a folded state, the airbag body is located inside the side wing; or, the airbag body extends from the inside of the side wing to the outside of the side wing.

[0017] In some embodiments, the side protection assembly is provided with a tear structure that is torn when the airbag body is inflated, thereby relieving the constraint of the fabric cover on the inflation of the airbag body.

[0018] In some embodiments, the tear structure is a tear line provided on the fabric cover, the tear line is located in the direction of the airbag body's inflation movement, and after the airbag body is torn by inflation, the airbag body bursts out from the torn part of the fabric cover to the outside of the fabric cover.

[0019] In some embodiments, the tear line is located on the fabric cover inside the side wing, and the direction of inflation of the airbag body intersects obliquely with the extension direction of the tear line.

[0020] In some embodiments, the tear line is located on the fabric cover directly in front of or above the side wing, and the direction of inflation of the airbag body intersects perpendicularly with the extension direction of the tear line.

[0021] In some embodiments, the fabric cover is entirely fitted over the outside of the side wing, and the tear structure is a tear line provided on the fabric cover. The tear line is away from the direction of movement of the airbag body during inflation. When the airbag body is torn during inflation, the fabric cover is completely detached from the side wing.

[0022] In some embodiments, the tearing structure is disposed at the connection between the side wing and the fabric cover, and the fabric cover is detached from the side wing when the airbag body is inflated and torn.

[0023] In some embodiments, the fabric cover is elastic, and the fabric cover undergoes elastic deformation when the airbag body is inflated.

[0024] In some embodiments, when the airbag body inflates, the fabric cover unfolds as the airbag body expands.

[0025] In some embodiments, the side protection components are respectively disposed on the left and right sides of the backrest. When the airbag body is inflated, the airbag body extends in front of the side protection components and inward towards the side protection components. And / or, the side protection components are respectively disposed on the left and right sides of the seat, and when the airbag body is inflated, the airbag body extends upward toward the side protection components and toward the inside of the side protection components; And / or, the side protection components are respectively disposed on the left and right sides of the connection between the seat and the backrest. When the airbag body is inflated, the airbag body extends forward and upward toward the side protection component and toward the inside of the side protection component.

[0026] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: In the child safety seat of the present invention, when the airbag body is in a folded state, it is located on the left and right sides of the bearing space, so that the setting of the airbag assembly does not affect the comfort of the child safety seat. When a car collision occurs, after the airbag body inflates, at least part of it is located in front of the backrest, and vertically above the seat and below the top of the backrest. This allows the inflated airbag body to be positioned in front of the passenger, between the passenger's legs and head. Thus, when the impact causes the passenger's head to swing forward, the inflated airbag body can support the passenger's head. At the same time, the inflated airbag body also prevents the passenger's entire body from moving forward, providing sufficient and effective protection for the passenger's head, neck, and chest, preventing injury from strong impacts, thereby improving the protective effect of the child safety seat.

[0029] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] In the following description, the directions "front," "back," "left," "right," "up," and "down" all refer to... Figure 4 In the figure, the right direction is "front", the left direction is "rear", the upper direction is "up", and the lower direction is "down". The directions perpendicular to the paper are "left" and "right". The above definitions of directions are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0031] The child safety seat of this embodiment includes a seat body and an airbag assembly disposed on the seat body.

[0032] like Figures 1-43 As shown, the seat body includes a seat 1 and a backrest 2. The backrest 2 is located at the rear of the seat 1, and a carrying space for a child to sit in is formed between the backrest 2 and the seat 1.

[0033] The seat body may also include side protection components, which are respectively disposed on the left and right sides of the bearing space. Specifically, the side protection components may be disposed on the left and right sides of the backrest 2, and the side protection components at this position are denoted as 3a. The side protection components may also be disposed on the left and right sides of the seat 1, and the side protection components at this position are denoted as 3b. The side protection components may also be disposed on the left and right sides of the connection between the seat 1 and the backrest 2, and the side protection components at this position are denoted as 3c. Of course, side protection components may also be disposed on the left and right sides of any two or all three of the three: the seat 1, the backrest 2, and the connection between the seat 1 and the backrest 2.

[0034] The seat body may also include a headrest 4 disposed on the backrest 2. Preferably, the headrest 4 can be slidably disposed on the backrest 2 so that the height of the headrest 4 on the backrest 2 can be adjusted according to the height of the child using it.

[0035] The airbag components are respectively installed on the left and right side protection components. The airbag components can be installed on the left and right side protection components of any one of the three: seat 1, backrest 2, and the connection between seat 1 and backrest 2.

[0036] The airbag assembly includes an airbag body 5, which has a folded state and an inflated state.

[0037] When the car is in normal driving, both the left and right airbag bodies 5 are in a folded state, and the left and right airbag bodies 5 are respectively housed in the side protection components on the corresponding sides, thus being located on the left and right sides of the load-bearing space, as shown below. Figures 1-6 , Figures 14-19 , Figure 27 , Figure 28 , Figures 31-36 As shown.

[0038] Upon impact, the airbag bodies 5 on both sides inflate and deploy from the side protection components toward the load-bearing space. When inflated, at least a portion of each airbag body 5 is positioned directly in front of the backrest 2, and vertically above the seat 1 and below the top edge of the backrest 2. Specifically, when inflated, the airbag body 5 is positioned vertically below the headrest 4 and above the seat 1. This positions the inflated airbag body 5 in front of the occupant, between the occupant's legs and head. When the impact causes the occupant's head to swing forward, the inflated airbag body 5 supports the occupant's head and simultaneously prevents the occupant's entire body from moving forward. This provides effective protection for the occupant's head, neck, and chest, preventing injury from strong impacts and improving the protective effect of the child safety seat. Figures 7-13 ,like Figures 20-26 , Figures 33-39 As shown.

[0039] When both the left and right airbag bodies 5 are inflated, the pair of airbag bodies on the left and right sides can come into contact and form mutual restraint, thereby providing stable support for the airbag bodies 5.

[0040] Specifically, when the airbag body 5 is inflated, the pair of airbag bodies 5 on the left and right sides abut against each other in the left-right direction, and the two abut against the center of the front of the backrest 2, as shown. Figures 7-9 , Figures 20-22 , Figures 37-39As shown. Alternatively, the airbag bodies 5 on the left and right sides are stacked on top of each other in the vertical direction; or the airbag bodies 5 on the left and right sides are stacked on top of each other in the front-back direction.

[0041] When the airbag body 5 is in an inflated state, there may also be a gap between the ends of the airbag bodies 5 on the left and right sides in the left and right directions.

[0042] The airbag assembly may also include a restraint structure connected to the airbag body 5 to restrain the position of the airbag body 5 in the inflated state, thereby providing stable support for the airbag body 5.

[0043] The restraint structure includes a pull cord, which can be connected between the side protection assembly and the airbag body 5, or between the two ends of the airbag body 5. The pull cord is tensioned when the airbag body 5 is inflated.

[0044] When the airbag body 5 is inflated, it includes a first airbag portion 51 and a second airbag portion 52. The first airbag portion 51 extends entirely in the left-right direction and is at least partially located in front of the backrest 2. The second airbag portion 52 extends entirely in the vertical direction and is disposed near the side protective assembly. The thickness of the first airbag portion 51 in the left-right direction is greater than the thickness of the second airbag portion 52 in the left-right direction, that is, the airbag body 5 on each side can form an L-shaped structure. Preferably, the first airbag portion 51 is located at the upper end of the second airbag portion 52, so that the first airbag portion 51 is closer to the occupant's head, thereby supporting the occupant's head and reducing the sway angle of the occupant's head in the event of a collision.

[0045] The left and right ends of the first airbag sections 51 on both sides abut against the middle of the front of the backrest 2, as shown. Figures 7-9 , Figures 20-22 , Figures 37-39 As shown. Alternatively, there may be a small gap between the left and right ends of the first airbag portions 51 on both sides. Alternatively, the first airbag portions 51 on both sides may also be stacked in the vertical direction or in the front-back direction.

[0046] When the airbag body 5 is inflated, it can form a C-shaped structure with the opening facing backward, or a long strip structure. The inflated shape of the airbag body 5 can also be other structures, as long as it can support the occupant's head and prevent the occupant from moving forward.

[0047] The side protection assembly includes a side wing 31 and a fabric cover 32 disposed on the side wing 31. The side wing 31 is made of a rigid material to provide support. The fabric cover 32 may be disposed inside the side wing 31; or, half or most of the structure of the side wing 31 facing the load-bearing space may be partially covered by the fabric cover 32; or, the fabric cover 32 may also fully cover the side wing 31. The fabric cover 32 improves passenger comfort. The airbag assembly is enclosed within the fabric cover 32.

[0048] The side protection assembly may be provided with a tear structure that can be torn when the airbag body 5 is inflated, thereby relieving the constraint of the fabric cover 32 on the inflation of the airbag body 5 and allowing the airbag body 5 to reach an inflated state. Alternatively, the side protection assembly may be provided with an opening that allows the airbag body 5 to extend out of the opening into the load-bearing space when it is inflated.

[0049] The tear structure can be a tear line 321 provided on the fabric cover 32, and the tear line 321 can be located in the direction of movement of the airbag body 5 during inflation, such as... Figure 1 , Figure 14 and Figure 31 As shown. After the airbag body 5 is torn during inflation, tear line 321 extends from the tear in the fabric cover 32 to the outside of the fabric cover 32, as shown. Figure 11 , Figure 24 , Figure 29 and Figure 41 As shown.

[0050] The tear line 321 can be located on the fabric cover 32 directly in front of and / or directly above the side wing 31. At this time, the direction of the airbag body 5 inflation is perpendicular to the extension direction of the tear line 321. After the airbag body 5 inflates and tears the tear line 321 and bursts out of the fabric cover 32, it extends towards the front of and / or directly above the tear line 321 and towards the middle of the bearing space.

[0051] The tear line 321 can also be located on the fabric cover 32 facing the inside of the side wing 31. Preferably, the tear line 321 is close to the front end or upper end of the side wing 31. At this time, the direction of the airbag body 5 inflating and expanding is obliquely intersecting the extension direction of the tear line 321. After the airbag body 5 inflates and expands, tears the tear line 321 and rushes out of the fabric cover 32, it extends obliquely forward and / or obliquely upward towards the tear line 321 and towards the middle of the bearing space.

[0052] For the side protection component that fully covers the side wings 31 with the fabric cover 32, the tear line 321 can also be set away from the direction of inflation of the airbag body 5. If the tear line 321 is set in the opposite direction of inflation of the airbag body 5, the tear line 321 will be torn after the airbag body 5 is inflated and torn, and the airbag body 5 will expand and press against the fabric cover 32, causing the fabric cover 32 to detach from the side wings 31 as a whole.

[0053] The tear structure can also be a weak area with a certain area set on the fabric cover 32.

[0054] The tearing structure can also be set at the connection between the cover 32 and the side wing 31. When the airbag body 5 is inflated and torn, the connection between the cover 32 and the side wing 31 is broken, and the airbag body 5 expands and presses against the cover 32, causing the cover 32 to detach from the side wing 31 as a whole.

[0055] The fabric cover 32 may not have a tearing structure. The fabric cover 32 may be elastic. When the airbag body 5 inflates, the airbag body 5 presses against the fabric cover 32, causing the fabric cover 32 to elastically deform and move synchronously with the airbag body 5. For example... Figure 13 , Figure 26 , Figure 30 and Figure 43 As shown.

[0056] The cover 32 may also be non-elastic. The cover 32 has a margin. The excess cover 32 is folded and stored on the side of the cover 32 facing the side wing 31. The cover 32 can be folded by sewing or pleats. When the airbag body 5 is inflated, the airbag body 5 presses against the cover 32 to unfold the cover 32.

[0057] The cloth cover 32 can also be partially set inside the side wing 31. When the airbag body 5 is inflated, the airbag body 5 presses against the cloth cover 32, causing the cloth cover 32 to be gradually pulled out from inside the side wing 31.

[0058] Alternatively, a receiving structure matching the shape of the airbag body 5 after inflation can be pre-set on the cloth cover 32. When the airbag body 5 is inflated, the airbag body 5 presses against the cloth cover 32, causing the airbag body 5 to enter the receiving structure.

[0059] The specific locations of the airbag components are given in several specific embodiments below: Example 1 In this embodiment, such as Figures 1-13 As shown, the airbag components are respectively housed within the side protection components 3a on the left and right sides of the backrest 2. When the airbag body 5 is in the folded state, the airbag body 5 is housed inside the fabric cover 32 of each side protection component 3a, and located within the fabric cover 32 inside the side wing 31. When the airbag body 5 inflates, it can push the fabric cover 32, causing it to detach from the side wing 31 as the airbag body 5 moves. Figure 13 As shown, when the airbag body 5 inflates, it can also tear open the tear line 321 and burst out to the outside of the cloth cover 32, as... Figure 11 As shown.

[0060] If a tear line 321 is provided on the fabric cover 32, the tear line 321 extends in the vertical direction, and the length of the tear line 321 can be the same as or slightly less than the length of the side wing 31 in the vertical direction.

[0061] Tear line 321 can be provided on the fabric cover 32 located directly in front of the side wing 31. Tear line 321 can also be provided on the fabric cover 32 located inside the side wing 31 and close to the front end face of the side wing 31.

[0062] Example 2 In this embodiment, when the airbag body 5 is in a folded state, the airbag body 5 is respectively disposed inside the fabric cover 32 of the side protection component 3a on each side, and extends from the fabric cover 32 inside the side wing 31 to the fabric cover 32 outside the side wing 31 (not shown). The rest is the same as in embodiment 1.

[0063] Example 3 In this embodiment, such as Figures 14-26 As shown, the airbag components are respectively installed inside the side protection components 3a on the left and right sides of the backrest 2. When the airbag body 5 is in the folded state, the airbag body 5 is respectively installed between the side wings 31 and the fabric cover 32 of the side protection components 3a on the left and right sides. Specifically, the airbag body 5 is located between the inner side of the side wing 31 and the inner fabric cover 32.

[0064] The airbag body 5 can be fixedly connected to the side wing 31 or the cloth cover 32. Specifically, the side wing 31 or the cloth cover 32 is provided with multiple fixing points, and the airbag body 5 is provided with multiple connecting parts, which are connected one-to-one to the multiple fixing points.

[0065] The rest is the same as in Example 1.

[0066] Example 4 In this embodiment, when the airbag body 5 is in a folded state, the airbag body 5 extends from the inner side of the side wing 31 and between the inner fabric cover 32 to the outer side of the side wing 31 and between the outer fabric cover 32, as shown. Figure 27 and Figure 28 As shown in the diagram. A schematic diagram of the airbag body 5 after inflation is shown in the diagram. Figure 29 and Figure 30 As shown. The rest is the same as in Example 3.

[0067] Example 5 In this embodiment, such as Figures 31-43 As shown, the airbag components are respectively installed in the side protection components 3a on the left and right sides of the backrest 2. Each side wing 31 is provided with a receiving groove 311, and the receiving groove 311 is located inside the side wing 31. When the airbag body 5 is in the folded state, the airbag body 5 is installed in the receiving groove 311, that is, the airbag body 5 is located inside the side wing 31.

[0068] The side of the receiving groove 311 facing the fabric cover 32 can be completely opened to form an outlet. Alternatively, the side of the receiving groove 311 facing the fabric cover 32 can be covered by a cover plate, forming an outlet at the cover plate. The structural strength of the cover plate is relatively weaker than that of the side wing 31, and the airbag body 5 can break through the cover plate when it is inflated. When the airbag body 5 is inflated, it first rushes out of the outlet to the outside of the receiving groove 311 and then pushes the fabric cover 32 so that it moves with the airbag body 5 and detaches from the side wing 31. Alternatively, after the airbag body 5 rushes out of the receiving groove 311, it tears along the tear line 321 and rushes out of the fabric cover 32. The rest is the same as in Embodiment 1.

[0069] Example 6 In this embodiment, the receiving groove 311 extends from the inner side of the side wing 31 to the outer side of the side wing 31, so that when the airbag body 5 is in the folded state, the airbag body 5 extends from the inner side of the side wing 31 to the outer side of the side wing 31 (not shown). The rest is the same as in embodiment 5.

[0070] Example 7 In this embodiment, the airbag components are respectively disposed within the side protection components 3b on the left and right sides of the seat 1. When the airbag body 5 is in the folded state, the airbag body 5 is disposed inside the fabric cover 32 of the side protection components 3b on the left and right sides. It can be located in the fabric cover 32 inside the side wing 31, or it can extend from the fabric cover 32 inside the side wing 31 to the fabric cover 32 outside. When the airbag body 5 inflates, it can push the fabric cover 32, causing it to move with the airbag body 5 and detach from the side wing 31. When the airbag body 5 inflates, it can also tear open the tear line 321 and burst out to the outside of the fabric cover 32.

[0071] If a tear line 321 is provided on the fabric cover 32, the tear line 321 extends in the front-to-back direction, and the length of the tear line 321 can be the same as or slightly less than the length of the side wing 31 in the front-to-back direction.

[0072] Tear line 321 can be set on the fabric cover 32 located directly above the side wing 31, or tear line 321 can be set on the fabric cover 32 located inside the side wing 31 and near the upper end surface of the side wing 31.

[0073] The rest is the same as in Example 1.

[0074] Example 8 In this embodiment, the airbag assemblies are respectively disposed within the side protection assemblies 3b on the left and right sides of the seat 1.

[0077] Example 9 In this embodiment, the airbag assemblies are respectively disposed within the side protection assemblies 3b on the left and right sides of the seat 1. Each side wing 31 is provided with a receiving groove 311. The receiving groove 311 can be located on the inner side of the side wing 31, or it can extend from the inner side of the side wing 31 to the outer side of the side wing 31. When the airbag body 5 is in a folded state, the airbag body 5 is disposed within the receiving groove 311, that is, the airbag body 5 can be located on the inner side of the side wing 31, or it can extend from the inner side of the side wing 31 to the outer side of the side wing 31. The side of the receiving groove 311 facing the fabric cover 32 can be completely open to form an outlet. Alternatively, the side of the receiving groove 311 facing the fabric cover 32 can also be covered by a cover plate, forming an outlet at the cover plate. The structural strength of the cover plate is relatively weaker than that of the side wing 31, and the airbag body 5 can break through the cover plate when it is inflated. When the airbag body 5 inflates, it first bursts out of the outlet to the outside of the receiving groove 311 and then pushes the cloth cover 32 so that it detaches from the side wing 31 as the airbag body 5 moves. Alternatively, after the airbag body 5 bursts out of the receiving groove 311, the tear line 321 is torn and it bursts out of the cloth cover 32. The rest is the same as in embodiment 7.

[0078] Example 10 In this embodiment, the airbag components are respectively disposed within the side protection components 3c on the left and right sides of the connection between the seat 1 and the backrest 2. When the airbag body 5 is in a folded state, the airbag body 5 is disposed inside the fabric cover 32 of the side protection components on the left and right sides. It can be located in the fabric cover 32 inside the side wing 31, or it can extend from the fabric cover 32 inside the side wing 31 to the fabric cover 32 outside. When the airbag body 5 inflates, it can push the fabric cover 32, causing it to move away from the side wing 31 with the movement of the airbag body 5. When the airbag body 5 inflates, it can also tear open the tear line 321 and burst out to the outside of the fabric cover 32.

[0079] If a tear line 321 is provided on the fabric cover 32, the tear line 321 is divided into two segments. The first segment extends in the vertical direction, and the second segment extends in the front-back direction. The lower part of the first segment intersects with the rear part of the second segment.

[0080] Example 11 In this embodiment, the airbag components are respectively disposed within the side protection components 3c on the left and right sides of the connection between the seat 1 and the backrest 2. When the airbag body 5 is in a folded state, the airbag body 5 is disposed between the side wings 31 and the fabric covers 32 of the side protection components 3c on the left and right sides. Specifically, the airbag body 5 is located between the inner side of the side wing 31 and the inner fabric cover 32, or the airbag body 5 extends from the inner side of the side wing 31 and the inner fabric cover 32 to the outer side of the side wing 31 and the outer fabric cover 32.

[0081] The airbag body 5 can be fixedly connected to the side wing 31 or the cloth cover 32. Specifically, the side wing 31 or the cloth cover 32 is provided with multiple fixing points, and the airbag body 5 is provided with multiple connecting parts, which are connected one-to-one to the multiple fixing points.

[0082] The rest is the same as in Example 10.

[0083] Example 12 In this embodiment, the airbag assembly is respectively installed in the side protection assembly 3c on the left and right sides of the connection between the seat 1 and the backrest 2. Each side wing 31 is provided with a receiving groove 311. The receiving groove 311 can be located inside the side wing 31 or can extend from the inside of the side wing 31 to the outside of the side wing 31. When the airbag body 5 is in the folded state, the airbag body 5 is installed in the receiving groove 311, that is, the airbag body 5 can be located inside the side wing 31 or can extend from the inside of the side wing 31 to the outside of the side wing 31.

[0084] The side of the receiving groove 311 facing the fabric cover 32 can be completely opened to form an outlet. Alternatively, the side of the receiving groove 311 facing the fabric cover 32 can be covered by a cover plate, forming an outlet at the cover plate. The structural strength of the cover plate is relatively weaker than that of the side wing 31, and the airbag body 5 can break through the cover plate when it is inflated. When the airbag body 5 is inflated, it first rushes out of the outlet to the outside of the receiving groove 311 and then pushes the fabric cover 32 so that it moves with the airbag body 5 and detaches from the side wing 31. Alternatively, after the airbag body 5 rushes out of the receiving groove 311, the tear line 321 is torn and it rushes out of the fabric cover 32. The rest is the same as in embodiment 10.
