[0040] Airbags are a key component of a vehicle's safety system. When a car is involved in an accident or is about to be involved in an accident, the inflator within the airbag generates gas and rapidly fills the airbag, causing it to inflate and deploy, protecting passengers and preventing injury. However, current airbag mounting brackets prevent the airbag from deploying entirely during an accident or when an accident is imminent. This can damage the windshield, preventing the airbag from effectively protecting passengers.

[0041] In this regard, the present application provides an airbag bracket, comprising: a bracket body and a support and limit assembly, wherein the bracket body can constitute an airbag accommodating space, and the airbag accommodating space includes a first space for accommodating the Z-fold portion of the airbag and a second space for accommodating the coiled portion of the airbag, with the first space being located above the second space. The support and limit assembly is relatively disposed at the contact position between the Z-fold portion and the coiled portion, and is used to enable the Z-fold portion to deploy in a predetermined direction during airbag deployment. A channel exists between the first space and the second space, and the coiled portion and the Z-fold portion are an integral structure. The connection between the coiled portion and the Z-fold portion passes through the channel, so that the Z-fold portion is accommodated within the first space.

[0042] The present application accommodates the Z-fold portion in the first space and sets the Z-fold portion in the first space through a support and limit assembly, so that the airbag can be deployed into the vehicle in a predetermined direction, thereby reducing damage to the airbag and better protecting the lives of passengers to avoid passenger injuries.

[0043] This application provides an airbag bracket for mounting a curtain airbag (CAB). Specifically, the bracket mounts the curtain airbag on either side of the vehicle's roof, protecting the passenger's head in side collisions or rollovers. When the vehicle detects a side impact or rollover risk, the curtain airbag rapidly inflates, forming a protective barrier that reduces the impact on the passenger's head and mitigates the risk of injury.

[0044] The airbag bracket of this embodiment will be explained below with reference to specific drawings. Figure 1 It is a structural schematic diagram of an airbag bracket provided in an embodiment of the present application.

Figure 7 yes Figure 1 Enlarged view of point A in the middle. Figure 8 It is a structural schematic diagram of the isolation plate provided in an embodiment of the present application.

[0045] In this embodiment, the airbag bracket includes a bracket body, which defines an airbag accommodating space 3. The airbag accommodating space 3 is used to accommodate the airbag, that is, the airbag is installed in the airbag accommodating space 3. The bracket body includes a first bracket 1 and a second bracket 2. In one example, the first bracket 1 and the second bracket 2 are integrally formed and connected to form the airbag accommodating space 3. In another example, the first bracket 1 and the second bracket 2 are detachably connected to form the airbag accommodating space 3.

[0046] Furthermore, in the structure in which the first bracket 1 and the second bracket 2 are integrally formed and connected to form the airbag accommodating space 3, the first bracket 1 includes an integrally formed upper portion and a lower portion, wherein the upper portion of the first bracket 1 includes an integrally formed vertical connection positioning plate 11 and a limiting plate 12, and the vertical connection positioning plate 11 and the limiting curved plate 121 are connected in an L-shape. Specifically, the vertical connection positioning plate 11 is arranged along the vertical direction, and the vertical connection positioning plate 11 is square and has a shape that is compatible with the vehicle body. For example, in one example, the vertical connection positioning plate 11 is rectangular, and the middle portion of the vertical connection positioning plate 11 is set to a curved shape with an arc relative to both ends in the vertical direction. In addition, a connection hole 7 is provided at the center position of the vertical connection positioning plate 11, and the connection hole 7 cooperates with the connecting piece on the vehicle body to fix the first bracket 1 to the vehicle body. In one example, the opening of the connection hole 7 is square in shape. Correspondingly, the connection member includes a square protrusion, and the protrusion can be snapped into the connection hole 7, thereby connecting the vertical connection positioning plate 11 to the vehicle body.

[0047] The limiting plate 12 is arranged horizontally, with a limiting curved panel 121 provided in the middle of the limiting plate 12. The limiting curved panel 121 is recessed in the first space 31. Specifically, the limiting plate 12 is mostly configured as a hollow structure, with the limiting curved panel 121 disposed within the hollow structure. The middle portion of the limiting curved panel 121 is configured as a downwardly concave curved panel, and the curved panel is recessed in the first space 31. Furthermore, the middle portion of the limiting curved panel 121 is concave, i.e., the middle portion of the limiting curved panel 121 is curved downward and gradually extends horizontally upward toward its ends. The limiting curved panel 121 can cooperate with the opposing isolation plate 51 (described below) to compress and secure the Z-fold portion 41 accommodated between the limiting curved panel 121 and the isolation plate 51.

[0048] It should be noted that in the embodiment of the present application, there is no specific limitation on the extent of the downward bend of the middle portion of the limiting curved plate 121, as long as it meets the operating requirements. Of course, the limiting curved plate 121 can also be a flat plate, and through the interaction between the flat plate and the isolation plate 51, the Z-folded portion 41 contained in the first space 31 can also be compressed and fixed.

[0049] The lower portion of the first bracket 1 includes a U-shaped plate 13, wherein the first side wall end of the U-shaped plate 13 is integrally connected to the limiting plate 12, and the second end 512 of the isolation plate 51 (described below) is disposed on the wall plate where the second side wall end of the U-shaped plate 13 is located. The isolation plate 51 and the U-shaped plate 13 form a second space 32. Figure 1 As shown, the opening of the U-shaped plate 13 is oriented in the front-to-back direction, facilitating airbag assembly. Furthermore, to facilitate observation of the distribution of the airbag within the airbag accommodation space 3, visualization openings 6 are provided on the first and second sidewalls of the U-shaped plate 13. Specifically, the first sidewall of the U-shaped plate 13 is referred to as the first panel 131, and the second sidewall of the U-shaped plate 13 is referred to as the second panel 132. The first sidewall is located at the top of the first panel 131, and the second sidewall is located at the top of the second panel 132. Each of the first and second panels 131 and 132 has a visualization opening 6, with the visualization opening 6 of the first panel 131 being larger than that of the second panel 132. In one example, the visualization opening 6 is square or triangular in shape. The provision of the visualization opening 6 also reduces the overall weight of the lower portion. In a preferred embodiment, the visualization opening 6 of the first panel 131 extends through the limiting curved panel 121.

[0050] In addition, in this embodiment, an airbag tearing opening 8 is provided at the lower end of the U-shaped plate 13. Specifically, the airbag tearing opening 8 is provided at the lowest position of the U-shaped plate 13, and the airbag tearing opening 8 is a long strip structure. Of course, the airbag tearing opening 8 may also be other structures, such as the airbag tearing opening 8 may also be an elliptical structure. The airbag tearing opening 8 releases the airbag during the airbag deployment process. The airbag tearing opening 8 is usually a weakened area pre-set on the airbag fabric, and this part of the structure is made easier to tear or break than the surrounding area through stitching or other means. When the vehicle collides and the airbag is triggered, the presence of the airbag tearing opening 8 ensures that the airbag can be deployed quickly and controllably in a preset manner and speed.

[0051] In this embodiment, the second bracket 2 includes a transverse connecting plate 21. The first end of the transverse connecting plate 21 is connected to the second side wall end of the U-shaped plate 13, and the second end of the transverse connecting plate 21 abuts the lower end surface of the limiting plate 12. Specifically, the transverse connecting plate 21 is a square structure as a whole, and the length of the transverse connecting plate 21 is equal to the length of the second side wall end of the U-shaped plate 13. It should be supplemented that the first bracket 1 includes an integrally formed upper part and a lower part, and then when the first bracket 1 is formed, the first bracket 1 is formed with an upper part and a lower part according to a preset size, specifically, in the vertical direction, there is an offset gap between the vertical connection positioning plate 11 and the second side wall end of the U-shaped plate 13, and the second side wall end of the U-shaped plate 13 is arranged on the outside of the vertical connection positioning plate 11. An installation gap is provided between the second side wall end of the U-shaped plate 13 and the limiting plate 12, and the installation gap can accommodate the transverse connecting plate 21. When the transverse connecting plate 21 is accommodated in the installation gap, the first end of the transverse connecting plate 21 is integrally connected to the second sidewall end of the U-shaped plate 13, and the second end of the transverse connecting plate 21 abuts the lower end surface of the limiting plate 12. The provision of the transverse connecting plate 21 not only facilitates the connection between the first bracket 1 and the second bracket 2, but also improves the stability of the connection between the first bracket 1 and the second bracket 2.

[0052] In one example, in order to further improve the stability of the connection between the transverse connecting plate 21 and the limiting plate 12, a fastening structure is further provided, such as Figure 5 and Figure 6 As shown, the fastening structure includes a limiting platform 22 and a limiting hole 23, wherein the limiting hole 23 is provided on the limiting plate 12, the limiting platform 22 is fixed to the transverse connecting plate 21 and can connect the limiting plate 12 through the limiting hole 23. Specifically, in one example, the number of the limiting platform 22 and the limiting hole 23 can be set to two respectively, the limiting platform 22 is provided at opposite ends in the length direction of the transverse connecting plate 21, and the limiting hole 23 is provided on the limiting plate 12 corresponding to the limiting platform 22. In addition, in order to improve the fastening effect, the column body of the limiting platform 22 gradually becomes thicker in the direction from top to bottom, so that the first bracket 1 can press the limiting plate 12 downward on the transverse connecting plate 21 under the action of its own gravity, thereby making the connection between the limiting platform 22 and the limiting hole 23 more stable. In addition, in one example, the limiting platform 22 and the limiting hole 23 can be connected in an interference fit manner.

[0053] The airbag is installed in the airbag accommodation space 3. The airbag accommodation space 3 includes a first space 31 for accommodating the Z-fold portion 41 of the airbag and a second space 32 for accommodating the coiled portion 42 of the airbag. The first space 31 is located above the second space 32. A passage 33 is formed between the first space 31 and the second space 32. The coiled portion 42 and the Z-fold portion 41 are integrally formed, and the connection between the coiled portion 42 and the Z-fold portion 41 passes through the passage 33, allowing the Z-fold portion 41 to be accommodated within the first space 31. A support and stop assembly is positioned relative to the contact point between the Z-fold portion 41 and the coiled portion 42 to ensure that the Z-fold portion 41 can expand in a predetermined direction during airbag deployment.

[0054] Specifically, in one example, the support and limiting assembly includes an isolation plate 51, and the isolation plate 51 includes a first end 511 and a second end 512 opposite to each other. There is a gap between the first end 511 and the inner wall of the bracket body to form a channel 33 between the first space 31 and the second space 32. The second end 512 is connected to the inner wall of the bracket body to divide the airbag accommodating space 3 into the first space 31 and the second space 32. Furthermore, in one example, the isolation plate 51 is a square plate, and the length of the isolation plate 51 is equal to the length of the second side wall end of the U-shaped plate 13. The second end 512 of the isolation plate 51 is integrally formed with the wall panel where the second side wall end of the U-shaped plate 13 is located. The isolation plate 51 is arranged horizontally and is parallel to the limiting plate 12. The first end 511 of the isolation plate 51 remains free and unconnected to any component. Specifically, a gap exists between the first end 511 of the isolation plate 51 and the wall panel where the first sidewall of the U-shaped plate 13 is located. This gap serves as the passage 33 connecting the second space 32 to the first space 31. The isolation plate 51 is positioned above the visual opening 6 and adjacent to the limiting plate 12, ensuring that the first space 31 is larger than the second space 32. In this embodiment, the isolation plate 51, the second sidewall of the U-shaped plate 13, the transverse connecting plate 21, the limiting plate 12, and the curved limiting plate 121 in the middle of the limiting plate 12 collectively enclose the first space 31. The isolation plate 51 supports the Z-fold 41, while the first space 31 restricts the Z-fold 41. Accordingly, the isolation plate 51 and the wall panels where the first and second sidewalls of the U-shaped plate 13 are located collectively enclose the second space 32. The second space 32 may limit the coiled portion 42 .

[0055] In this embodiment, the support and limiting assembly includes a fixed sewing thread 52 and / or a fixed sewing tape 53, wherein the fixed sewing thread 52 and / or the fixed sewing tape 53 are connected to the contact position of the Z-fold portion 41 and the winding portion 42 in the vertical direction to shape the Z-fold portion 41 and the winding portion 42 at the contact position.

[0056] Specifically, in one example, a fixed sewing thread 52 is vertically connected to the contact position of the Z-fold portion 41 and the coiled portion 42 to fix the Z-fold portion 41 and the coiled portion 42 in the contact position. The number of fixed sewing threads 52 is set to at least one, and each fixed sewing thread 52 can be sewn to at least one fold line of the coiled portion 42 and the Z-fold portion 41. When there are multiple fixed sewing threads 52, each fixed sewing thread 52 is arranged in parallel in the horizontal direction, and each fixed sewing thread 52 is connected to the Z-fold portion 41 and the coiled portion 42, so that the Z-fold portion 41 and the coiled portion 42 are distributed in the airbag accommodation space 3.

[0057] In one example, a fixing sewing tape 53 is vertically connected to the contact point between the Z-fold portion 41 and the looped portion 42 to fix the Z-fold portion 41 and the looped portion 42 in their contact position. The number of fixing sewing tapes 53 is set to at least one, and each fixing sewing tape 53 can be sewn to at least one fold line of the looped portion 42 and the Z-fold portion 41. When there are multiple fixing sewing tapes 53, each fixing sewing tape 53 is arranged horizontally in parallel, and each fixing sewing tape 53 is connected to the Z-fold portion 41 and the looped portion 42, so that the Z-fold portion 41 and the looped portion 42 are distributed within the airbag accommodation space 3.

[0058] In one example, a fixing sewing thread 52 and a fixing sewing tape 53 are respectively connected vertically to the contact positions of the Z-fold portion 41 and the loop portion 42 to fix the Z-fold portion 41 and the loop portion 42 in the contact position. The number of fixing sewing threads 52 and fixing sewing tapes 53 is set to at least one, and each fixing sewing thread 52 and fixing sewing tape 53 is sewn at intervals to at least one fold line of the loop portion 42 and the Z-fold portion 41. When the fixing sewing threads 52 and fixing sewing tapes 53 are arranged at intervals, the fixing sewing threads 52 and fixing sewing tapes 53 are arranged horizontally and parallel, and each fixing sewing thread 52 and fixing sewing tape 53 is connected to the Z-fold portion 41 and the loop portion 42, so that the Z-fold portion 41 and the loop portion 42 are distributed in the airbag accommodation space 3.

[0059] It should be noted that the hardness of the fixing sewing thread 52 and the fixing sewing tape 53 not only allows the Z-fold portion 41 and the coiled portion 42 to be connected so that the Z-fold portion 41 is placed in the first space 31 and the coiled portion 42 is placed in the second space 32, but also allows the Z-fold portion 41 and the coiled portion 42 to break in time when they deform, so as not to affect the ejection of the airbag from the second space 32 along the airbag tear 8.

[0060] It should also be noted that when the support and limiting assembly includes a fixed sewing thread 52 and / or a fixed sewing tape 53, there is no isolation plate 51 in the airbag accommodating space 3, that is, the junction between the winding part 42 and the Z-fold part 41 can be shaped only by the fixed sewing thread 52 and / or the fixed sewing tape 53, so that the Z-fold part 41 can be unfolded in a predetermined direction when the airbag is unfolded.

[0061] In this embodiment, the support and limit assembly further includes a limit opening 54 and a limit hanger 55. The limit opening 54 is provided in the support body and opens vertically. The extended end 411 of the Z-fold portion 41 can be drawn out of the limit opening 54. The extended end 411 of the Z-fold portion 41 is the end of the Z-fold portion 41 not connected to the coiled portion 42. The limit hanger 55 is provided to the side of the limit opening 54 and can be connected to the extended end 411 of the Z-fold portion 41 to limit and secure the extended end 411 of the Z-fold portion 41.

[0062] Specifically, the limiting opening 54 and the limiting hanging piece 55 are respectively provided on the second bracket 2, that is, the limiting opening 54 and the limiting hanging piece 55 are respectively provided on the horizontal connecting plate 21. Figure 3 and Figure 4 As shown, the limiting opening 54 is in the shape of an elongated rectangle, and the length of the limiting opening 54 is slightly larger than the width of the Z-fold portion 41, so that the extended end 411 of the Z-fold portion 41 can be drawn out from the limiting opening 54. A limiting hanger 55 is provided on the side of the limiting opening 54, and the limiting hanger 55 includes a limiting hook, and the limiting hook is bent and extended upward. The limiting hanger 55 can be connected to the extended end 411 of the Z-fold portion 41 to limit and fix the extended end 411 of the Z-fold portion 41. In one example, the extended end 411 of the Z-fold portion 41 is provided with a connecting component, and the connecting component can be hung on the limiting hanger 55 to achieve the limit and fixation of the extended end 411 of the Z-fold portion 41.

[0063] In this embodiment, a limiting opening 54 and a limiting hanger 55 are provided on the second bracket 2, allowing the extended end 411 of the Z-fold portion 41 to pass through the limiting opening 54 and then be attached to the limiting hanger 55, thereby achieving fixed positioning of the extended end 411 of the Z-fold portion 41. Furthermore, a partition plate 51 confines the Z-fold portion 41 to the first space 31, and the coiled portion 42 to the second space 32. A passage 33 exists between the first space 31 and the second space 32, allowing the Z-fold portion 41 to expand in a predetermined direction during airbag deployment.

[0064] The present application provides an airbag bracket, comprising: a bracket body and a support and limit assembly, wherein the bracket body can constitute an airbag accommodating space 3, and the airbag accommodating space 3 includes a first space 31 for accommodating a Z-fold portion 41 of the airbag and a second space 32 for accommodating a coiled portion 42 of the airbag, wherein the first space 31 is located above the second space 32. The support and limit assembly is relatively arranged at the contact position of the Z-fold portion 41 and the coiled portion 42, and is used to enable the Z-fold portion 41 to deploy in a predetermined direction during deployment of the airbag.
