[0040] Airbags are one of the important components of the automobile safety system. When an accident occurs or is about to occur, the gas generator in the airbag will generate gas and quickly fill the airbag, so that the airbag will expand and deploy, which can protect the lives of passengers and prevent them from getting injured. However, the bracket currently used to fix the airbag will cause the airbag inside to deploy as a whole when the car is in an accident or is about to have an accident, and the windshield may cause damage to the airbag, making it unable to better protect the lives of 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-folded part of the airbag and a second space for accommodating the coiled part of the airbag, and the first space is located above the second space.

There is a channel between the first space and the second space, the coiled part and the Z-folded part are an integrated structure, and the connection between the coiled part and the Z-folded part passes through the channel so that the Z-folded part is accommodated in 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] The present application provides an airbag bracket, which is used to install a curtain airbag (CAB), that is, the airbag bracket is a pillar for installing the curtain airbag on both sides of the top of the vehicle, which is used to protect the head of the passenger in a side collision or rollover event.

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

[0045] In this embodiment, the airbag bracket includes a bracket body, the bracket body forms an airbag accommodating space 3, and 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] Further, in the structure in which the first bracket 1 and the second bracket 2 are integrally 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, the vertical connection positioning plate 11 is square, and has a shape adapted to 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 at both ends relative to the vertical direction. In addition, a connecting hole 7 is provided at the center position of the vertical connection positioning plate 11, and the connecting hole 7 cooperates with a 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, and correspondingly, the connection member includes a square-shaped protrusion, and the protrusion can be snapped into the connection hole 7, so as to connect the vertical connection positioning plate 11 to the vehicle body.

[0047] The limiting plate 12 is arranged in the horizontal direction, and a limiting curved panel 121 is arranged in the middle of the limiting plate 12, and the limiting curved panel 121 is recessed in the first space 31. Specifically, most of the limiting plate 12 is arranged as a hollow structure, and the limiting curved panel 121 is arranged in the hollow structure, and the middle of the limiting curved panel 121 is arranged as a curved panel with a downward depression, and the curved panel is recessed in the first space 31. Further, the middle of the limiting curved panel 121 is concave, that is, the middle of the limiting curved panel 121 is bent downward, and the middle gradually extends horizontally upward toward its two ends, and the limiting curved panel 121 can cooperate with the relative isolation plate 51 (described below) to press and fix the Z-folded 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 restriction on the downward bending amplitude of the middle portion of the limiting curved panel 121, as long as the working requirements are met. Of course, the limiting curved panel 121 can also be a flat plate, and the Z-folded portion 41 contained in the first space 31 can also be pressed and fixed by the cooperation between the flat plate and the isolation plate 51.

[0049] The lower part 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 with the limiting plate 12, and the second end 512 of the isolation plate 51 (described below) is arranged on the wall plate where the second side wall end of the U-shaped plate 13 is located, and 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 in the front-to-back direction, which can facilitate the assembly of the airbag. Further, in order to facilitate the observation of the distribution of the airbag in the airbag accommodating space 3, the wall panels where the first side wall end and the second side wall end of the U-shaped plate 13 are respectively located are provided with a visualization opening 6. Specifically, the wall panel where the first side wall end of the U-shaped plate 13 is located is called the first wall panel 131, and the wall panel where the second side wall end of the U-shaped plate 13 is located is called the second wall panel 132. The first side wall end is located at the top of the first wall panel 131, and the second side wall end is located at the top of the second wall panel 132. A visualization opening 6 is respectively provided on the first wall panel 131 and the second wall panel 132, and the size of the visualization opening 6 of the first wall panel 131 is larger than the size of the visualization opening 6 of the second wall panel 132. In one example, the shape of the visualization opening 6 is square or triangular, etc. The setting of the visualization opening 6 can also reduce the overall weight of the lower part. In a preferred example, the visualization opening 6 of the first wall panel 131 is set through the limiting curved panel 121.

[0050] In addition, in the present embodiment, the lower end of the U-shaped plate 13 is provided with an airbag tearing opening 8. 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 against 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 upper part and a lower part that are integrally formed, and then when the first bracket 1 is formed, the first bracket 1 is formed according to the upper part and the lower part of the preset size, specifically, in the vertical direction, the vertical connection positioning plate 11 and the second side wall end of the U-shaped plate 13 have an offset gap, 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 with the second side wall end of the U-shaped plate 13, and the second end of the transverse connecting plate 21 abuts against the lower end surface of the limiting plate 12. The provision of the transverse connecting plate 21 can not only realize the connection between the first bracket 1 and the second bracket 2, but also improve 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 arranged 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 arranged at the opposite ends of the length direction of the transverse connecting plate 21, and the limiting hole 23 is arranged 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, so that the connection between the limiting platform 22 and the limiting hole 23 is more stable. In addition, in one example, the limiting platform 22 and the limiting hole 23 can be connected in an interference manner.

[0053] The airbag is installed in the airbag accommodating space 3, which includes a first space 31 for accommodating the Z-folded portion 41 in the airbag and a second space 32 for accommodating the coiled portion 42 in the airbag, and the first space 31 is located above the second space 32. There is a channel 33 between the first space 31 and the second space 32, and the coiled portion 42 and the Z-folded portion 41 are an integral structure, and the connection between the coiled portion 42 and the Z-folded portion 41 passes through the channel 33 so that the Z-folded portion 41 is accommodated in the first space 31. The support and limit assembly is relatively arranged at the contact position of the Z-folded portion 41 and the coiled portion 42, and is used to enable the Z-folded portion 41 to be deployed in a predetermined direction when the airbag is deployed.

[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, and 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. Further, 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 horizontally arranged and parallel to the limiting plate 12. The first end 511 of the isolation plate 51 remains in a free state, and the first end 511 of the isolation plate 51 is not connected to any component, that is, there is a gap between the first end 511 of the isolation plate 51 and the wall plate where the first side wall end of the opposite U-shaped plate 13 is located, and the gap is a passage 33 from the second space 32 to the first space 31. The isolation plate 51 is located above the visual opening 6, and the isolation plate 51 is arranged close to the limiting plate 12, so that the space of the first space 31 is larger than the space of the second space 32. In this embodiment, the isolation plate 51, the second side wall end of the U-shaped plate 13, the transverse connecting plate 21, the limiting plate 12 and the limiting curved plate 121 in the middle of the limiting plate 12 are enclosed together to form the first space 31. The isolation plate 51 can provide support for the Z-folded portion 41, and the first space 31 can limit the Z-folded portion 41. Accordingly, the isolation plate 51, the first side wall end of the U-shaped plate 13 and the wall plates where the second side wall end are located are enclosed together to form the second space 32. The second space 32 may limit the winding 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 fix the Z-fold portion 41 and the winding portion 42 at the contact position.

[0056] Specifically, in one example, the fixed sewing thread 52 is 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. The number of the 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 winding 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 winding portion 42, so that the Z-fold portion 41 and the winding portion 42 are distributed in the airbag accommodating space 3.

[0057] In one example, the fixing sewing tape 53 is 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. The number of the 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 winding portion 42 and the Z-fold portion 41. When there are multiple fixing sewing tapes 53, each fixing sewing tape 53 is arranged in parallel in the horizontal direction, and each fixing sewing tape 53 is connected to the Z-fold portion 41 and the winding portion 42, so that the Z-fold portion 41 and the winding portion 42 are distributed in the airbag accommodating space 3.

[0058] In one example, the fixed sewing thread 52 and the fixed sewing tape 53 are respectively connected to the contact positions of the Z-folding portion 41 and the winding portion 42 in the vertical direction to shape the Z-folding portion 41 and the winding portion 42 at the contact position. The number of the fixed sewing thread 52 and the fixed sewing tape 53 is set to at least one, and each fixed sewing thread 52 and the fixed sewing tape 53 are sewn at intervals on at least one fold line of the winding portion 42 and the Z-folding portion 41. When the fixed sewing thread 52 and the fixed sewing tape 53 are arranged at intervals, the fixed sewing thread 52 and the fixed sewing tape 53 are arranged in parallel in the horizontal direction, and each fixed sewing thread 52 and the fixed sewing tape 53 will be connected to the Z-folding portion 41 and the winding portion 42, so that the Z-folding portion 41 and the winding portion 42 are distributed in the airbag accommodating space 3.

[0059] It should be noted that the fixed sewing thread 52 and the fixed sewing tape 53 have a hardness that not only allows the Z-folded portion 41 and the coiled portion 42 to be connected so that the Z-folded 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-folded portion 41 and the coiled portion 42 to be broken in time when they are deformed, so as not to affect the airbag from being ejected from the second space 32 along the airbag tearing hole 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 portion 42 and the Z-fold portion 41 can be shaped only by fixing the sewing thread 52 and / or the fixed sewing tape 53, so that the Z-fold portion 41 can be unfolded in a predetermined direction when the airbag is unfolded.

[0061] In this embodiment, the support limit assembly further includes a limit opening 54 and a limit hanging piece 55, wherein the limit opening 54 is provided on the support body, and the opening direction of the limit opening 54 is along the vertical direction. The extended end 411 of the Z-folded portion 41 can be led out from the limit opening 54, and the extended end 411 of the Z-folded portion 41 is an end of the Z-folded portion 41 that is not connected to the winding portion 42. The limit hanging piece 55 is provided on the side of the limit opening 54, and the limit hanging piece 55 can be connected to the extended end 411 of the Z-folded portion 41 to limit and fix the extended end 411 of the Z-folded portion 41.

[0062] Specifically, the limiting opening 54 and the limiting hanging member 55 are respectively arranged on the second bracket 2, that is, the limiting opening 54 and the limiting hanging member 55 are respectively arranged on the transverse 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-folding portion 41, so that the extended end 411 of the Z-folding portion 41 can be led out from the limiting opening 54. The limiting hanging member 55 is arranged on the side of the limiting opening 54, and the limiting hanging member 55 includes a limiting hook, and the limiting hook is bent and extended upward. The limiting hanging member 55 can be connected to the extended end 411 of the Z-folding portion 41 to limit and fix the extended end 411 of the Z-folding portion 41. In one example, the extended end 411 of the Z-folding portion 41 is provided with a connecting component, and the connecting component can be hung on the limiting hanging member 55 to achieve the limit and fixation of the extended end 411 of the Z-folding portion 41.

[0063] In this embodiment, a limiting opening 54 and a limiting hanging piece 55 are provided on the second bracket 2, so that the extended end 411 of the Z-folded portion 41 passes through the limiting opening 54 and is hung on the limiting hanging piece 55, thereby realizing the fixed limiting of the extended end 411 of the Z-folded portion 41.
