[0031] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 5 An airbag 100 according to an embodiment of the present invention is described. The airbag 100 includes an airbag body 10 .

[0032] Specifically, if Figure 5 As shown, after the airbag body 10 is deployed, it is suitable for being arranged opposite to a plurality of seats arranged along the width direction of the vehicle. In this embodiment, the height direction of the vehicle is Figure 1 The first direction A in the vehicle width direction is Figure 1 The second direction B in .

[0033] In this application, the airbag 100 is connected to the gas generator 41. When an accident occurs, the gas generator 41 inflates the interior of the airbag 100 and deploys the airbag body 10. The interior of the airbag body 10 is a complete cavity. After deployment, the airbag body 10 along the second direction B, that is, the width direction of the vehicle, is arranged opposite to the two adjacent front seats of the vehicle, so as to realize the protection of the heads of the occupants of the two adjacent front seats of the vehicle by the airbag 100.

[0034] According to the airbag 100 of the embodiment of the present invention, the airbag body 10 covers multiple seats of the vehicle along the width direction of the vehicle after being deployed, which facilitates to increase the protection area formed after the airbag body 10 is deployed, thereby realizing the effective protection of the airbag 100 for the occupants of the two adjacent front seats of the vehicle, improving the protection strength of the airbag 100, and improving the reliability of the airbag 100. At the same time, the airbag body 10 has a complete chamber inside, which avoids slippage when the occupant's head contacts the airbag body 10, further improving the protection effect of the airbag 100, and only one gas generator 41 is required to supply gas to the airbag body 10, effectively reducing the cost and processing difficulty.

[0035] In the present application, the deployed airbag 100 is suitable for protecting the heads of the occupants in the middle and right front seats of the vehicle.

[0036] According to some embodiments of the present invention, after deployment, the airbag body 10 is configured such that its length along the vehicle width direction is greater than its length along the vehicle height direction. That is, the length of the airbag body 10 along the second direction B is greater than its length along the first direction A. Thus, by designing the airbag body 10 to be longer along the vehicle width direction, the protection area of ​​the airbag 100 along the second direction B can be increased, effectively protecting the occupants of the center and right front seats of the vehicle.

[0037] According to some embodiments of the present invention, the projected shape of the deployed airbag body 10 along the length of the vehicle is preferably an oblong or elliptical shape. Thus, by optimizing the deployed shape of the airbag body 10, the airbag body 10 is positioned opposite multiple seats along the width of the vehicle, maximizing protection for occupants in the center and right front seats and improving the reliability of the airbag 100.

[0038] According to some embodiments of the present invention, Figure 1 and Figure 2As shown, the airbag body 10 includes: a first airbag sheet 11 and a second airbag sheet 12, the second airbag sheet 12 is suitable for being arranged on a side of the first airbag sheet 11 adjacent to the seat along the thickness direction of the airbag body 10, and the edge of the second airbag sheet 12 and the edge of the first airbag sheet 11 are connected to each other.

[0039] The first airbag sheet 11 and the second airbag sheet 12 are exactly the same in shape and size. The first airbag sheet 11 and the second airbag sheet 12 are opposite to each other along the thickness direction of the airbag body 10. The second airbag sheet 12 is arranged adjacent to the seat along the thickness direction of the airbag body 10. The first airbag sheet 11 is arranged on the side of the second airbag sheet 12 away from the seat along the thickness direction of the airbag body 10. The edge of the second airbag sheet 12 and the edge of the first airbag sheet 11 are connected by stitches. The edge of the first airbag sheet 11 includes a first stitching point 50, a second stitching point 51, a third stitching point 52, and a fourth stitching point 53 arranged at intervals clockwise, and the edge of the second airbag sheet 12 includes a fifth stitching point 54, a sixth stitching point 55, a seventh stitching point 56, and an eighth stitching point 57 arranged at intervals counterclockwise. The first stitching point 50, the second stitching point 51, the third stitching point 52, and the fourth stitching point 53 of the first airbag sheet 11 correspond to the fifth stitching point 54, the sixth stitching point 55, the seventh stitching point 56, and the eighth stitching point 57 of the second airbag sheet 12, respectively.

[0040] Thus, by connecting the edge of the second airbag sheet 12 and the edge of the first airbag sheet 11 to each other, a complete chamber is formed inside the airbag body 10. Only one gas generator 41 is required to achieve effective protection of the occupant by the airbag 100, thereby reducing production costs.

[0041] According to some embodiments of the present invention, the airbag 100 further includes: at least one drawstring 20 , which is disposed in the airbag body 10 , with both ends of the drawstring 20 connected to opposite surfaces of the second airbag panel 12 and the first airbag panel 11 .

[0042] The drawstring 20, at both ends of the airbag body 10 along its thickness, is connected to adjacent surfaces of the second airbag panel 12 and the first airbag panel 11, respectively, to control the desired deployment direction of the airbag body 10 and increase the thickness of the airbag body 10 in the area that contacts the occupant's head. Thus, by providing at least one drawstring 20 within the airbag body 10, the deployment direction of the airbag body 10 and the thickness of the airbag 100 are easily controlled, providing sufficient head cushioning distance for the occupant, improving the protective effect of the airbag 100 on the occupant's head, and enhancing the reliability of the airbag 100.

[0043] According to some embodiments of the present invention, Figure 1 and Figure 2As shown, there are multiple drawstrings 20, including at least one first drawstring 21 and at least one second drawstring 22. The first drawstring 21 and the second drawstring 22 are spaced apart along the width direction of the airbag body 10, and the length of the first drawstring 21 is less than the length of the second drawstring 22.

[0044] The first drawstring 21 and the second drawstring 22 are along Figure 1 The first direction A, that is, the width direction of the airbag body 10, is arranged at intervals, and the first pull strap 21 is arranged along the first direction A adjacent to the upper edge of the airbag body 10, and the second pull strap 22 is arranged along the first direction A between the first pull strap 21 and the lower edge of the airbag body 10, and the area of ​​the airbag body 10 where the second pull strap 22 is arranged is the main area of ​​contact with the occupant's head. Since the area of ​​the airbag body 10 where the first pull strap 21 is arranged is not the main area of ​​contact with the occupant's head, the length of the first pull strap 21 is less than the length of the second pull strap 22, which can reduce the thickness of the area where the first pull strap 21 is arranged at the upper end of the airbag body 10.

[0045] Therefore, by arranging the first and second pull straps 21 and 22 at intervals along the width direction of the airbag body 10, and the length of the first pull strap 21 being smaller than the length of the second pull strap 22, the airflow in the area where the first pull strap 21 is arranged on the airbag body 10 can be effectively reduced, facilitating the airflow to other areas, thereby accelerating the deployment speed of the airbag 100. At the same time, the thickness of the area where the airbag body 10 contacts the occupant's head can be effectively strengthened, thereby improving the safety and reliability of the airbag 100.

[0046] According to some embodiments of the present invention, one end of the first draw strap 21 is connected to the first airbag panel 11. The distance between the one end of the first draw strap 21 and the nearest side edge of the first airbag panel 11 along the width direction of the airbag body 10 is L1. The other end of the first draw strap 21 is connected to the second airbag panel 12. The distance between the other end of the first draw strap 21 and the nearest side edge of the second airbag panel 12 along the width direction of the airbag body 10 is L2. L1 and L2 satisfy the following: L1 < L2. That is, the distance between the one end of the first draw strap 21 connected to the first airbag panel 11 and the adjacent upper edge of the airbag body 10 along the first direction A is L1, and the distance between the other end of the first draw strap 21 connected to the second airbag panel 12 and the adjacent upper edge of the airbag body 10 along the first direction A is L2. L1 is less than L2. The one end of the first draw strap 21 connected to the first airbag panel 11 is higher than the other end of the first draw strap 21 connected to the second airbag panel 12 along the first direction A. Therefore, through the inclined setting of the first pull strap 21, during the deployment stage of the airbag 100, the first pull strap 21 can pull the corresponding area of ​​the airbag body 10, further reducing the airflow in the area of ​​the airbag body 10 where the first pull strap 21 is set, prompting the airflow to flow to other areas, and accelerating the deployment speed of the airbag 100.

[0047] Optionally, one end of the second drawstring 22 is connected to the first airbag panel 11, and the distance between the one end of the second drawstring 22 and the nearest side edge of the first airbag panel 11 along the width direction of the airbag body 10 is L3. The other end of the second drawstring 22 is connected to the second airbag panel 12, and the distance between the other end of the second drawstring 22 and the nearest side edge of the second airbag panel 12 along the width direction of the airbag body 10 is L4. L3 and L4 satisfy the following: L3 < L4. That is, the distance between the one end of the second drawstring 22 connected to the first airbag panel 11 and the adjacent lower edge of the airbag body 10 along the first direction A is L3, and the distance between the other end of the second drawstring 22 connected to the second airbag panel 12 and the adjacent lower edge of the airbag body 10 along the first direction A is L4. L3 is less than L4, and the one end of the second drawstring 22 connected to the first airbag panel 11 is lower than the other end of the second drawstring 22 connected to the second airbag panel 12 along the first direction A. Therefore, through the inclined setting of the second pull strap 22, during the deployment stage of the airbag 100, the second pull strap 22 can support the corresponding area of ​​the airbag body 10, preventing the airbag 100 from contacting the occupant's leg area, and improving the protection effect of the airbag 100 on the occupant's head.

[0048] In this application, L1 and L2 satisfy: L1 < L2, and L3 and L4 satisfy: L3 < L4. This further provides support and lifting for the airbag body 10, preventing the airbag body 10 from sagging excessively under the action of gravity, and allowing the occupant's head to effectively fall within the protection area of ​​the airbag body 10.

[0049] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, there are multiple first pull belts 21, and the multiple first pull belts 21 are spaced apart along the length direction of the airbag body 10. Figure 1 The first pull straps 21 are arranged at intervals along the second direction B, i.e., the longitudinal direction of the airbag body 10. Thus, by arranging the plurality of first pull straps 21 at intervals along the longitudinal direction of the airbag body 10, the pulling effect of the first pull straps 21 on the airbag body 10 can be enhanced, further reducing the airflow in the area of ​​the airbag body 10 where the first pull straps 21 are located, and promoting airflow to other areas.

[0050] Optionally, there are multiple second drawstrings 22, and the multiple second drawstrings 22 are spaced apart along the length direction of the airbag body 10. That is, the multiple second drawstrings 22 are spaced apart along the length direction of the airbag body 10. Figure 1 Thus, by arranging the plurality of second drawstrings 22 at intervals along the length direction of the airbag body 10, the supporting effect of the second drawstrings 22 on the airbag body 10 can be improved, thereby preventing the airbag body 10 from sagging excessively under the action of gravity.

[0051] In the present application, a plurality of first pull straps 21 are spaced apart along the length direction of the airbag body 10, and at the same time, a plurality of second pull straps 22 are spaced apart along the length direction of the airbag body 10, thereby simultaneously improving the lifting effect of the first pull strap 21 on the airbag body 10 and the supporting effect of the second pull strap 22 on the airbag body 10, so that the airbag 100 can effectively protect the occupant's head.

[0052] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, when there are multiple second tension belts 22 , the multiple second tension belts 22 include a first sub-tension belt 23 and a second sub-tension belt 24 , and the length of the first sub-tension belt 23 is smaller than that of the second sub-tension belt 24 .

[0053] In this embodiment, the first sub-tie 23 and the second sub-tie 24 are spaced apart along the second direction B. The first sub-tie 23 is positioned adjacent to the right front seat of the vehicle along the second direction B, while the second sub-tie 24 is positioned adjacent to the center front seat of the vehicle along the second direction B. The length of the first sub-tie 23 is shorter than that of the second sub-tie 24, and the thickness of the area of ​​the airbag body 10 where the first sub-tie 23 is positioned is smaller than that of the area of ​​the airbag body 10 where the second sub-tie 24 is positioned. Thus, by designing the first sub-tie 23 to be shorter than the second sub-tie 24, the airbag body 10 can obtain greater support force at the first sub-tie 23. Furthermore, airflow can more easily fill the area of ​​the airbag body 10 where the first sub-tie 23 is positioned, and can quickly flow to the area of ​​the airbag body 10 where the second sub-tie 24 is positioned.

[0054] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the multiple first traction straps 21 are symmetrically arranged about the central axis along the width direction of the airbag body 10, i.e., the first direction A. Thus, the symmetrical arrangement of the multiple first traction straps 21 along the central axis of the airbag body 10 in the first direction A facilitates uniform airflow distribution within the area of ​​the airbag body 10 where the multiple first traction straps 21 are located, ensuring uniform force on the upper end of the airbag body 10. The multiple first traction straps 21 include a third sub-traction strap 25 and a fourth sub-traction strap 26. The third sub-traction strap 25 is located adjacent to the right front seat of the vehicle, and the fourth sub-traction strap 26 is located adjacent to the center front seat of the vehicle.

[0055] Optionally, the plurality of second pull straps 22 are symmetrically arranged about the central axis along the width direction of the airbag body 10, i.e., in the first direction A. That is, the first sub-pull straps 23 and the second sub-pull straps 24 are symmetrically arranged about the central axis of the airbag body 10 in the first direction A. Thus, by symmetrically arranging the plurality of second pull straps 22 along the central axis of the airbag body 10 in the first direction A, the support provided by the plurality of second pull straps 22 to the airbag body 10 can be further enhanced, ensuring uniform force on the lower end of the airbag body 10 and preventing the airbag body 10 from sagging excessively under the action of gravity.

[0056] In the present application, the plurality of first pull straps 21 are symmetrically arranged about the central axis along the width direction of the airbag body 10, and the plurality of second pull straps 22 are symmetrically arranged about the central axis along the width direction of the airbag body 10. This further evens out the force applied to the airbag body 10 and facilitates airflow from the area of ​​the airbag body 10 opposite the right front seat to the area opposite the center front seat.

[0057] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the plurality of drawstrings 20 further include: at least one third drawstring 27 , which is located between the first drawstring 21 and the second drawstring 22 in the width direction of the airbag body 10 .

[0058] In the present application, the third tie strap 27 is disposed between the first sub-tie strap 23 and the third sub-tie strap 25 along the first direction A. That is, the third tie strap 27 is disposed in the middle region of the airbag body 10 along the first direction A, and is positioned adjacent to the right front seat of the vehicle. Thus, by disposing the third tie strap 27 between the first tie strap 21 and the second tie strap 22 along the first direction A, when the airbag body 10 is deployed, primary support is provided for the area of ​​the airbag body 10 opposite the head of the right front seat occupant, ensuring the thickness of the airbag body 10 in this area and improving the protective effectiveness and reliability of the airbag 100.

[0059] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, one end of the third draw tape 27 connected to the first airbag panel 11 is adjacent to the second draw tape 22 on the first airbag panel 11 , and the other end of the third draw tape 27 connected to the second airbag panel 12 is adjacent to the first draw tape 21 on the second airbag panel 12 .

[0060] In this application, one end of the third pull strap 27 connected to the first airbag panel 11 is arranged adjacent to one end of the first sub-pull strap 23 connected to the first airbag panel 11, and the other end of the third pull strap 27 connected to the second airbag panel 12 is arranged adjacent to the other end of the third sub-pull strap 25 connected to the second airbag panel 12.

[0061] Therefore, by arranging the two ends of the third strap 27 adjacent to the first strap 21 and the second strap 22 respectively, the third strap 27 is arranged at an angle, which facilitates reducing the cavity of the area where the third strap 27 is adjacent to the second strap 22 in the airbag body 10, thereby facilitating the gas to flow from the area opposite to the right front seat occupant of the vehicle in the airbag body 10 to the area opposite to the middle front seat occupant of the vehicle as quickly as possible, facilitating the rapid deployment of the airbag 100 along the second direction B. At the same time, it can effectively provide support for the middle area of ​​the airbag body 10 to prevent the middle area of ​​the airbag body 10 from sagging due to gravity.

[0062] Furthermore, one end of the third strap 27 is connected to the first airbag panel 11. The distance between this end and the second strap 22 on the first airbag panel 11 is L5. The other end of the third strap 27 is connected to the second airbag panel 12. The distance between this end and the first strap 21 on the second airbag panel 12 is L6. L5 and L6 satisfy the following: L5 < L6. That is, the distance along the first direction A between the end of the third strap 27 connected to the first airbag panel 11 and the end of the first sub-strap 23 connected to the first airbag panel 11 is L5. The distance along the first direction A between the other end of the third strap 27 connected to the second airbag panel 12 and the other end of the third sub-strap 25 connected to the second airbag panel 12 is L6. L5 is less than L6. This further enhances the protective effect of the airbag body 10 on the head of the right front seat occupant of the vehicle.

[0063] According to some embodiments of the present invention, Figure 1 As shown, multiple vent holes 30 are formed on the same side surface in the thickness direction of the airbag body 10. The vent holes 30 are spaced apart along the length of the airbag body 10. In this embodiment, two vent holes 30 are formed in the first airbag panel 11. The two vent holes 30 extend through the first airbag panel 11 along the thickness direction of the airbag body 10 and are spaced apart between the drawstring 20 and the two side edges of the airbag body 10 along the second direction B. Thus, the provision of multiple vent holes 30 facilitates controlling the pressure within the cavity of the airbag body 10 after deployment. When an occupant's head contacts the airbag body 10, the airbag body 10 is compressed, and the vent holes 30 release air, thereby cushioning the occupant's head and facilitating adjustment of the degree of protection provided to the occupant.

[0064] Furthermore, the plurality of vent holes 30 are located between the first and second traction straps 21, 22 in the width direction of the airbag body 10 and in the first direction A. This facilitates adjusting the pressure of the cavity in the airbag body 10 corresponding to the areas where the first and second traction straps 21, 22 are located, thereby improving the safety and reliability of the airbag 100.

[0065] According to some embodiments of the present invention, Figure 1As shown, a mounting hole 31 is formed on the first airbag sheet 11. The mounting hole 31 is set away from the center line of the airbag body 10 in the longitudinal direction, that is, the mounting hole 31 is set close to one end of the airbag body 10 in the longitudinal direction.

[0070] Optionally, the length of the first sub-tie 23 is about 300 mm, the length of the second sub-tie 24 is about 400 mm, the length of the third sub-tie 25 is about 100 mm, the length of the fourth sub-tie 26 is about 100 mm, and the length of the third tie 27 is about 300 mm.

[0071] According to some embodiments of the present invention, Figure 3 and Figure 4As shown, the airbag body 10 further includes a third airbag panel 13 , which is connected between an edge of the second airbag panel 12 and an edge of the first airbag panel 11 .

[0072] The third airbag panel 13 has a rectangular cross-section and is positioned between the first airbag panel 11 and the second airbag panel 12. Along the thickness direction of the airbag body 10, the third airbag panel 13 is connected to the edges of the first airbag panel 11 and the edges of the second airbag panel 12, respectively. Thus, the provision of the third airbag panel 13 increases the thickness of the airbag body 10 after deployment, thereby increasing the energy absorption effect of the airbag 100 upon contact between the occupant and the airbag body 10, further enhancing the protective effect of the airbag 100 on the occupant.

[0073] In the present application, by providing a first airbag sheet 11, a second airbag sheet 12, and a third airbag sheet 13 connected to each other at their edges, and connecting the two ends of a plurality of drawstrings 20 to the inner surfaces of the first airbag sheet 11 and the second airbag sheet 12 adjacent to each other, the shape of the airbag body 10, the arrangement mode and length of the plurality of drawstrings 20 are optimized, and the deployment speed and direction of the airbag body 10 can be controlled. After receiving the ignition signal, the gas generator 41 begins to generate gas rapidly. After the gas enters the airbag body 10, the airbag body 10 first moves toward the right front seat of the vehicle along the thickness direction. After the occupant deploys and quickly fills the area opposite to the right-seat occupant, it deploys along the second direction B toward the front middle seat occupant of the vehicle, thereby improving the deployment efficiency of the airbag 100 and enabling the protection area formed after the airbag body 10 is deployed to effectively protect the heads of the occupants in the front middle seat and the right seat, ensuring the thickness of the airbag body 10 to provide sufficient buffering distance for the occupant's head. At the same time, multiple drawstrings 20 provide sufficient support for the airbag body 10, enabling the occupant's head to effectively fall within the protection area of ​​the airbag body 10, thereby improving the reliability of the airbag 100.

[0074] The airbag 100 in this application can be used not only to protect two passengers in the middle seat and the right seat, but also to protect a single passenger in the right seat only. It can protect two passengers without specially setting the installation position of the airbag 100, thereby improving the installation efficiency and practicality of the airbag 100.

[0075] Optionally, the shapes of the first airbag panel 11 , the second airbag panel 12 and the third airbag panel 13 are not limited and can be specifically designed according to the required protection area of ​​the occupant.

[0076] Optionally, the materials of the airbag body 10 and the drawstring 20 are not limited to non-coated and coated woven fabrics.

[0077] Optionally, the specific design position, length and sewing method of the drawstring 20 can be set according to actual needs, so that the airbag 100 can first be deployed toward the right seat along the thickness direction and then extend toward the middle seat, and the airbag 100 can effectively protect the occupant's head and chest area, and can provide support for the airbag body 10.

[0078] Optionally, the number of cavities inside the airbag body 10 can be specifically set according to actual needs, as long as it can effectively protect the occupants.

[0079] According to the second embodiment of the present invention, the instrument panel 40 is as follows: Figure 5 As shown, the instrument panel 40 includes an instrument panel body and an airbag 100. The airbag 100 is adapted to be positioned on the side of the instrument panel body facing the vehicle seat. The airbag 100 can be any of the airbags 100 described in the aforementioned embodiments. The airbag 100 can be secured to the side of the instrument panel body facing the vehicle seat via an airbag housing, without requiring support from the instrument panel body. Multiple drawstrings 20 are provided within the airbag body 10 to provide support during deployment, enabling the deployed airbag 100 to protect both occupants in the center and right seats.

[0080] According to some embodiments of the present invention, Figure 5 As shown, after deployment, the airbag body 10 is adapted to be positioned opposite two seats aligned along the width of the vehicle. The mounting point of the airbag 100 and the instrument panel body is offset from the centerline of the two seats in the vehicle width direction. This reduces the difficulty of installing the airbag 100, improves installation efficiency, and enhances the adaptability of the airbag 100.
