[0045] Additionally, in the following description, specific details are provided to provide a thorough understanding of the examples, however, one skilled in the art will appreciate that the examples can be practiced without these specific details.

[0046] The existing main sheet 10 generally has a weaving angle of 90°, which causes the portion thereof at the windshield to be easily torn after being impacted by high temperature, thereby causing the passenger airbag to fail.

[0047] Based on this, this specification proposes a solution: Figure 1 As described above, a passenger airbag of the present invention divides a main panel 10 into a passenger side fabric panel 11 and a windshield side fabric panel 12, and sets the weaving threads of the windshield side fabric panel 12 at a first inclination angle, so that the weaving threads of the windshield side fabric panel 12 are arranged more evenly, thereby better dispersing stress and reducing the risk of unidirectional tearing, thereby solving the problem in the prior art that the weaving thread angle of the main panel 10 is set to 90°, which easily causes the main panel 10 near the windshield to be torn.

[0048] The following describes the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0049] Example 1

[0050] like Figures 1 to 5 As shown, a passenger airbag of the present invention includes a main panel 10 and side panels 20 located on both sides of the main panel 10, wherein the side panels 20 are sewn on both sides of the main panel 10 and cooperate with the main panel 10 to form a cavity structure.

[0051] Wherein, air outlets are respectively provided on the two side pieces 20 .

[0052] The shapes of the main panel 10 and the side panel 20 can be flexibly set according to the actual shape of the passenger airbag after expansion.

[0053] Furthermore, the main panel 10 includes a passenger-side fabric panel 11 and a windshield-side fabric panel 12, which are sewn together so that after the passenger airbag is deployed, the passenger-side fabric panel 11 is at least partially oriented toward the occupant, and the windshield-side fabric panel 12 is at least partially oriented toward the windshield; wherein, the weaving yarn of the windshield-side fabric panel 12 has a first inclination angle in the length direction of the windshield-side fabric panel 12 to provide better tensile strength.

[0054] The passenger side fabric panel 11 and the windshield side fabric panel 12 are sewn together in the length direction of the main panel 10 .

[0055] Among them, by making the weaving threads of the windshield side fabric panel 12 have a first inclination angle in the length direction of the windshield side fabric panel 12, after the windshield side fabric panel 12 is subjected to high-pressure impact, the weaving threads of the windshield side fabric panel 12 can be arranged more evenly, so as to better disperse the stress and reduce the risk of unidirectional tearing.

[0056] Furthermore, the first inclination angle ranges from 30° to 60°.

[0057] Preferably, the first inclination angle ranges from 40 to 50 degrees.

[0058] More preferably, the first inclination angle is in the range of 45°.

[0059] When the first inclination angle is 45°, the transverse threads and the longitudinal threads of the windshield side fabric panel 12 can be simultaneously subjected to oblique forces when being pulled, thereby improving the tensile strength of the windshield side fabric panel 12 .

[0060] The windshield side fabric panel 12 may extend from the inlet of the gas generator plug of the passenger airbag to the top end area of ​​the windshield.

[0061] In some embodiments, the passenger side fabric panel 11 and the windshield side fabric panel 12 may be integrally connected, so that the weaving threads of the passenger side fabric panel 11 and the windshield side fabric panel 12 both have a first inclination angle.

[0062] In some embodiments, the passenger side fabric panel 11 and the windshield side fabric panel 12 can be set separately, and the two ends of the passenger side fabric panel 11 and the two ends of the windshield side fabric panel 12 are sewn together, and the gas generator plug inlet is set on the passenger side fabric panel 11 or the windshield side fabric panel 12. At this time, the two ends of the passenger side fabric panel 11 and the two ends of the windshield side fabric panel 12 can be sewn together using multiple stitches.

[0063] Among them, after the passenger side fabric panel 11 and the windshield side fabric panel 12 are separately provided, the weaving angle of the passenger side fabric panel 11 can be set to 90°.

[0064] In some embodiments, one end of the windshield side fabric panel 12 is connected to one end of the passenger side fabric panel 11, and the other end of the windshield side fabric panel 12 passes over the other end of the passenger side fabric panel 11 and is connected to the middle part of the passenger side fabric panel 11, so that the main panel 10 has a partial double-layer structure to increase the strength of the main panel 10.

[0065] The gas generator plug inlet may be provided on the passenger side fabric panel 11 or the windshield side fabric panel 12 according to the different connection points between the windshield side fabric panel 12 and the passenger side fabric panel 11 .

[0066] For example, when the windshield panel 12 passes over the gas generator insertion opening provided on the passenger side panel 11 and is sewn to the middle portion of the passenger side panel 11, the gas generator insertion openings are provided on both the passenger side panel 11 and the windshield panel 12, and correspond to each other in the upper and lower parts. In this case, when the gas generator passes through the gas generator insertion openings on the passenger side panel 11 and the windshield side panel 12 in sequence, the connection between the passenger side panel 11 and the windshield side panel 12 near the gas generator can be secured with a single stitch or without stitching.

[0067] Furthermore, the passenger airbag further includes a reinforcing sheet 30 , which is stacked with the windshield side fabric sheet 12 to enhance the strength of the main sheet 10 near the windshield glass side and prevent the windshield side fabric sheet 12 from being torn.

[0068] The size of the reinforcing sheet 30 may be slightly larger than the size of the windshield side fabric sheet 12 so as to completely cover the windshield side fabric sheet 12 .

[0069] Furthermore, the weaving threads of the reinforcing sheet 30 have a second inclination angle along the length direction of the reinforcing sheet 30 to increase the tensile strength of the reinforcing sheet 30 .

[0070] The second inclination angle ranges from 30° to 60°.

[0071] Preferably, the second inclination angle is in the range of 40 to 50 degrees.

[0072] More preferably, the second inclination angle is in the range of 45°.

[0073] Specifically, the reinforcing sheet 30 is first sewn and fixed to the windshield side fabric panel 12, and then sewn together with the passenger side fabric panel 11, so that the passenger side fabric panel 11, the windshield side fabric panel 12 and the reinforcing sheet 30 form a whole to enhance the strength of the main panel 10 and prevent the windshield side fabric panel 12 from being torn.

[0074] When the weaving thread inclination angle of the reinforcing sheet 30 is inconsistent with the weaving thread inclination angle of the passenger-side fabric panel 11 , the reinforcing sheet 30 and the passenger-side fabric panel 11 have better stitching strength, thereby preventing the main panel 10 from tearing at the stitching.

[0075] Preferably, the shape of the reinforcing piece 30 is substantially the same as that of the windshield side fabric panel 12 , but the size of the reinforcing piece 30 is larger than that of the windshield side fabric panel 12 .

[0076] Compared with the prior art which cuts with a 90° weaving angle, in this embodiment, the windshield side fabric panel 12 close to the windshield is cut with a 45° weaving angle, and the passenger side fabric panel 11 can continue to use a 90° weaving angle. As a result, after the fabric panels at different angles are sewn together, the combination between the passenger side fabric panel 11 and the windshield side fabric panel 12 can provide better sewing strength. Moreover, when the windshield side fabric panel 12 is cut at a 45° angle, the horizontal and vertical weaving threads of the windshield side fabric panel 12 are arranged more evenly, which can better disperse stress, reduce the risk of unidirectional tearing, and provide better tensile strength in multiple directions.

[0077] In this embodiment, the reinforcing sheet 30 is added, and the windshield side fabric sheet 12 and the reinforcing sheet 30 are fixedly sewn together and then spliced ​​and sewn with the passenger side fabric sheet 11 to form a whole, thereby enhancing the overall strength of the main sheet 10 and achieving better protection.

[0078] Example 2

[0079] like Figures 1-2 As shown, the difference between this embodiment and embodiment 1 is that it further includes a vertical pull belt 40 and a horizontal pull belt 41.

[0080] Specifically, the passenger airbag also includes a vertical pull strap 40 and a transverse pull strap 41. One end of the vertical pull strap 40 is connected to the passenger side fabric panel 11, and the other end extends to the gas generator plug inlet on the main panel 10, and is used to be put on the gas generator; the transverse pull strap 41 is connected between the passenger side fabric panel 11 and a side panel 20; wherein, when the passenger airbag is deployed, the vertical pull strap 40 pulls the passenger side fabric panel 11 toward the side panel of the occupant to form a receiving recess on the side panel of the passenger side fabric panel 11 toward the occupant; when the passenger airbag is deployed, under the pull of the transverse pull strap 41, an avoidance recess is formed on the side panel 20 to avoid the central control or display screen.

[0081] Among them, when the passenger airbag is deployed, one end of the vertical pull strap 40 is vertically connected to the passenger side fabric panel 11, so that an inner recess is formed on the side panel of the passenger side fabric panel 11 facing the passenger, so as to accommodate the passenger's face and limit the twisting between the passenger's face and the passenger's body; the other end of the passenger airbag is twisted to a horizontal position relative to one end of the passenger airbag, and then put on the gas generator and fixedly connected to the gas generator.

[0082] The vertical pull belt 40 may be a multi-layer structure or be provided in plurality to change the shape of the receiving recess.

[0083] The concave range of the receiving recess can also be adjusted by adjusting the length of the vertical pull belt 40 .

[0084] The vertical drawstring is located between the main panel 10 and the air guide bag 50 .

[0085] Among them, the connection positions of the two ends of the horizontal pull strap 41 can be flexibly set according to the position or size of the central control or large screen.

[0086] One end of the transverse drawstring 41 is connected to the side panel of the passenger-side fabric facing the passenger, and the other end is connected to the side panel.

[0087] This embodiment uses the vertical pull straps 40 and the horizontal pull straps 41 to pull the main panel 10 and the side panels 20, so as to provide good support for the passenger's face and avoid the central control or large screen.

[0088] Example 3

[0089] like Figure 1 、 6 As shown in Figures 1 to 8, the difference between this embodiment and embodiment 1 or embodiment 2 is that the passenger airbag also includes an air guide bag 50, which is built into the interior of the passenger airbag; the air guide bag 50 includes a connecting portion 51 and an expanding portion 52, the connecting portion 51 is provided with a gas generator plug inlet, and is connected to the main panel 10, and the expanding portion 52 cooperates with the connecting portion 51 to form a tubular structure with two air guide ports 53.

[0090] The width of at least part of the unfolded portion 52 is smaller than the distance between the two side panels 20 , so as to guide the gas to flow from the two air guide ports 53 toward the passenger-side fabric panel 11 after the gas enters the air bag 50 .

[0091] Among them, by making the width of at least part of the unfolding portion 52 smaller than the distance between the two side panels 20, sufficient space is reserved for the gas to flow to the passenger side fabric panel 11 after the gas enters the air guide bag 50, so as to avoid a large amount of gas impacting the side panel 20 and causing damage to the side panel 20.

[0092] Furthermore, the width of the connecting portion 51 is greater than the width of the portion where the main panel 10 is connected to the connecting portion 51, so that the connecting portion 51 covers the seam between the main panel 10 and the side panel 20, thereby preventing the chain seam between the main panel 10 and the side panel 20 from damaging the side panel 20 or the main panel 10.

[0093] Furthermore, a portion of the side panel 20 corresponding to the air guide port 53 is provided with a heat-insulating coating to prevent the side panel 20 from being damaged by high-temperature gas, which would cause the passenger airbag to fail.

[0094] Furthermore, the connecting portion 51 is provided on the main plate 10 through a reinforcing air guide plate.

[0095] In some embodiments, the air guide bag 50 is an integrated structure, which includes a connecting wide portion 54 and a trapezoidal narrow portion 55. The connecting wide portion 54 is connected to the main piece 10, and the trapezoidal narrow portion 55 is folded toward the connecting wide portion 54 and connected to the end of the connecting wide portion 54 to form a tubular structure with air guide ports 53 on both sides. The connecting wide portion 54 forms a connecting portion 51, and the trapezoidal narrow portion 55 is folded onto the connecting wide portion 54 to form an unfolding portion 52.

[0096] The width of the connecting wide portion 54 is greater than the distance between the two side panels 20, so that the connecting wide portion 54 can cover the seam between the main panel 10 and the side panel 20. The width of at least a portion of the trapezoidal narrow portion 55 is less than the distance between the two side panels 20, so that at least a portion of the width of the expanded portion 52 is less than the distance between the two side panels 20.

[0097] In other embodiments, the air guide bag 50 is a split structure, which includes a connecting fabric piece 56 and an expansion fabric piece 57. The connecting fabric piece 56 is connected to the main piece 10. The two ends of the expansion fabric piece 57 are connected to the two ends of the connecting fabric piece 56 to form a cylindrical structure with air guide ports 53 on both sides. The connecting fabric piece 56 forms a connecting portion 51, and the expansion fabric piece 57 is sewn to the connecting fabric piece 56 to form an expansion portion 52.

[0098] The width of the connecting fabric piece 56 is greater than the distance between the two side panels 20, so that the connecting fabric piece 56 can cover the seam between the main panel 10 and the side panel 20. The size of the unfolded fabric piece 57 is smaller than the distance between the two side panels 20, so that the width of at least part of the unfolded portion 52 is smaller than the distance between the two side panels 20.

[0099] In this specification, references to the same or similar parts between the various embodiments can be made to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the product embodiments described later, since they correspond to the methods, the description is relatively simple, and the relevant parts can be referred to the partial description of the system embodiment.

[0100] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
