Description

Passenger airbag and vehicle Technical Field

[0001] The present disclosure relates to the field of safety technology, and in particular to a passenger airbag and a vehicle. Background Art

[0002] In the related art, for the passenger airbag of a vehicle, the passenger airbag is installed in the dashboard in front of the passenger seat along the direction of vehicle travel, for example, it can be installed above the glove box of the dashboard and below the styling surface of the dashboard.

[0003] The passenger airbag in an autonomous vehicle (ALV) includes a side support structure to protect the sides of the passenger's head from collisions. In related technologies, the side support structure of the passenger airbag often needs to be sewn by special airbag panels or formed by pulling with a drawstring.

[0004] Because dashboard designs vary across vehicle models, the shape of the airbag panels during cutting results in low raw material utilization, leading to high costs. Furthermore, to achieve better performance, such as more stable airbag deployment, the drawstring inside the airbag cannot be eliminated, further increasing costs.

[0005] Summary of the Invention

[0006] In order to overcome the problems existing in the related art, the present disclosure provides a passenger airbag and a vehicle.

[0007] According to a first aspect of an embodiment of the present disclosure, the present disclosure provides a passenger airbag, comprising an airbag body, the airbag body comprising: a first panel; a second panel; and an intermediate panel, which is provided with a first end and a second end along the direction of vehicle travel, and a first side and a second side transverse to the direction of vehicle travel; the side edges of the first side and the second side of the intermediate panel are sewn together along the periphery of the first panel and the second panel, respectively, wherein the periphery length of the first panel and the second panel is greater than the side edge length of the first side and the second side of the intermediate panel to form an empty periphery that is not sewn together with the side edge of the intermediate panel, and the empty periphery is folded in half and sewn together with the sewing of the first end and the second end of the intermediate panel to form a pointed side ear.

[0008] In some embodiments, the first panel and the second panel have the same shape.

[0009] In some embodiments, after the airbag body is inflated and expanded, the middle panel forms a rear side surface that contacts the co-pilot, and the side ears are located on the rear side surface and form a head and neck protection area for the co-pilot together with the rear side surface, wherein the side ears extend in an oblique rear direction of the co-pilot and form an obtuse angle with the rear side surface.

[0010] In some embodiments, the first panel and the second panel both include a protrusion, the protrusion including an upper edge, a lower edge, and the empty edge between the upper edge and the lower edge. After the first end and the second end of the middle panel are sewn together, the upper edge and the lower edge are aligned so that the side ear extends toward the oblique rear direction of the driver.

[0011] In some embodiments, the first cutting piece and the second cutting piece further include a concave corner, which is recessed in the middle of the empty periphery along the direction of vehicle travel. When the empty periphery is folded and sewn to form the side ear portion, the concave corner reduces the sharpness of the side ear portion.

[0012] In some embodiments, after the airbag body is inflated and deployed, the middle panel further forms: a front side surface for abutting against a car windshield; and a lower side surface for abutting against a display screen on a car dashboard.

[0013] In some embodiments, the first panel and the second panel both include a recessed groove, and after the middle panel is sewn together with the first and second panels, a recessed portion adapted to the display screen is formed on the lower side of the middle panel.

[0014] In some embodiments, the passenger airbag further includes a gas generator for inflating the airbag, wherein the gas generator is located below the vehicle dashboard and in front of the display screen.

[0015] In some embodiments, the first panel and / or the second panel are provided with vent holes.

[0016] According to a second aspect of an embodiment of the present disclosure, the present disclosure provides a vehicle comprising the passenger airbag as described in the first aspect.

[0017] The technical solution provided by the embodiments of the present disclosure may include the following beneficial effects: pointed side ears are formed by cutting and sewing the first, second and middle pieces, which not only increases the utilization rate of the raw materials of the pieces and reduces the manufacturing cost of the airbag, but also eliminates the need for inner / outer pull straps to form the side ears, ensuring the stability of the airbag during deployment, and further reducing the manufacturing cost and process cost of the airbag.

[0024] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0025] In order to solve the above technical problems, the present disclosure provides a passenger airbag 100, which provides protection for an occupant located on the passenger side of a vehicle.

[0026] As shown in Figure 1, the passenger airbag 100 may include an airbag body 10 and a gas generator 20. The gas generator 20 is connected to the airbag body 10 and is used to quickly inflate the airbag body 10 when the vehicle collides.

[0027] The airbag body 10 includes a first panel 11 , a second panel 12 and a middle panel 13 .

[0028] When laid flat, the middle panel 13 is rectangular in shape. It includes a first end 131 and a second end 132 along its length, and a first side 133 and a second side 134 along its width. When the airbag body 10 is inflated and deployed, the middle panel 13 is arranged in the direction of vehicle travel, with the first panel 11 and the second panel 12 located on either side of the middle panel 13, transverse to the direction of vehicle travel.

[0029] As shown in FIG1 , when the middle panel 13 is sewn together with the first panel 11 and the second panel 12 , the side edges of the first side 133 and the second side 134 of the middle panel 13 are sewn together along the periphery of the first panel 11 and the second panel 12 , respectively.

[0030] As shown in Figure 1, when the middle panel 13 is sewn together with the first panel 11 and the second panel 12, points C1 and C5 of the middle panel 13 are aligned with points B1 and B3 of the first panel 11, respectively. Similarly, points C2 and C4 of the middle panel 13 are aligned with points A1 and A3 of the second panel 12, respectively.

[0031] Furthermore, the perimeter lengths of the first panel 11 and the second panel 12 are greater than the side edge lengths of the first side 133 and the second side 134 of the middle panel 13 to form an empty perimeter 14 that is not sewn to the side edges of the middle panel 13 .

[0032] As shown in FIG2 , the first end 131 and the second end 132 of the middle panel 13 are disposed relative to each other in the vertical direction, forming a pre-sewn state. As the first end 131 and the second end 132 of the middle panel 13 are sewn together, the hollow peripheral edge 14 is folded in half and sewn together to form the pointed side ears 15. The vertical direction is based on the direction shown in FIG2 and does not limit the middle panel 13 to a specific direction.

[0033] Specifically, when the first end 131 and the second end 132 of the middle panel 13 gradually approach each other, the empty peripheral edges 14 of the first panel 11 and the second panel 12 bulge or extend away from the middle panel 13 in a direction transverse to the direction of vehicle travel, so that the empty peripheral edge 14 of the first panel 11 is folded up and down at point B2, and the empty peripheral edge 14 of the second panel 12 is folded up and down at point A2. Then, points B1 and B3 of the first panel 11 gradually approach each other, and points A1 and A3 of the second panel 12 also gradually approach each other.

[0034] After the first end 131 and the second end 132 of the middle panel 13 are sewn together to form a seam line, points B1 and B3 of the first panel 11 coincide, and sections B1B2 and B3B2 of the hollow peripheral edge 14 of the first panel 11 coincide and are sewn together. Simultaneously, points A1 and A3 of the second panel 12 coincide, and sections A1A2 and A3A2 of the hollow peripheral edge 14 of the second panel 12 also coincide and are sewn together. Thus, the hollow peripheral edges 14 of the first and second panels 11, 12, and the middle panel 13 each form a pointed side ear portion 15.

[0035] The stitching line formed by sewing the first end 131 and the second end 132 of the middle panel 13, the stitching line formed by sewing the empty peripheral edge 14 of the first panel 11, and the stitching line formed by folding and sewing the empty peripheral edge 14 of the second panel 12 into a line are connected. When the airbag body 10 is inflated and unfolded, the stitching line can stabilize the side ear portion 15, eliminating the drawstring in the prior art and reducing material and process costs.

[0036] It can be seen that the pointed side ears 15 are formed by cutting and sewing the first, second, and middle panels 11, 12, 13. This not only increases the utilization rate of the raw materials of the panels, thereby reducing the manufacturing and process costs of the airbag, but also eliminates the need for inner and outer drawstrings, thereby ensuring the stability of the airbag during deployment, and further reducing the manufacturing and process costs of the airbag.

[0037] In some embodiments, after the airbag body 10 is inflated and expanded, the middle panel 13 forms a rear side surface 30 that contacts the co-pilot, and the side ears 15 are located on the rear side surface 30 and form a head and neck protection area for the co-pilot with the rear side surface 30, wherein the side ears 15 extend in the oblique rear direction of the co-pilot and form an obtuse angle with the rear side surface 30.

[0038] The angles formed by the stitching line formed by the first and second ends 131, 132 of the middle panel 13, and the stitching line formed by the stitching line formed by the unused peripheral edge 14 of the first panel 11, or the stitching line formed by the stitching line formed by the folded-over unused peripheral edge 14 of the second panel 12, are both obtuse. Therefore, when viewed from above, the head and neck protection area is roughly trapezoidal, ensuring that the airbag body 10 can accommodate the passenger's head when inflated and deployed.

[0039] Furthermore, when the first end 131 and the second end 132 of the middle panel 13 are sewn together, two alignment points can be provided on each of the first end 131 and the second end 132 to facilitate alignment and pre-sewing, thereby improving the speed and efficiency of sewing. As shown in FIG2 , the numbers 3 and 4 corresponding to the first end 131 are aligned and sewn together with the numbers 3 and 4 corresponding to the second end 132, respectively. Similarly, two alignment points are also provided on the empty periphery 14 of the first panel 11 and the empty periphery 14 of the second panel 12 to facilitate alignment and pre-sewing. As shown in FIG2 , the two numbers 1 and 2 on the empty periphery 14 of the first panel 11 are aligned and sewn together, and the two numbers 5 and 6 on the empty periphery 14 of the second panel 12 are aligned and sewn together.

[0040] In some embodiments, the first and second panels 11, 12 have the same shape. Therefore, after inflation and expansion, the airbag body 10, after removing the side ears 15, generally assumes a triangular prism structure. Having identically shaped first and second panels 11, 12 not only enhances interchangeability and reduces mold costs, but also allows for the simultaneous cutting of multiple first or second panels 11, 12 by overlapping multiple sheets of raw material.

[0041] In addition, the first panel 11, the second panel 12 and the middle panel 13 can be made of the same material, or the first panel 11 and the second panel 12 can be made of the same material and the middle panel 13 can be made of another material, which is not specifically limited here.

[0042] In some embodiments, both the first panel 11 and the second panel 12 include a protrusion 16. The protrusion 16 includes an upper edge 161, a lower edge 162, and a peripheral edge 14 located between the upper edge 161 and the lower edge 162. After the first end 131 and the second end 132 of the middle panel 13 are sewn together, the upper edge 161 and the lower edge 162 are aligned so that the side ear 15 extends diagonally to the rear of the driver. The upper edge 161 and the lower edge 162 are based on the upper edge 161 and the lower edge 162 shown in FIG. 2 and are not intended to define a specific direction for the protrusion.

[0043] Specifically, the upper edge 161 and the lower edge 162 of the protrusion 16 are roughly parallel, and the end of the protrusion 16 is a hollow edge 14. When the first end 131 and the second end 132 of the middle panel 13 are sewn together, the upper edge 161 and the lower edge 162 can be aligned up and down. After the airbag body 10 is inflated, the rear side surface 30 formed by the middle panel 13 can be flatter, reducing the impact on the face of the co-pilot occupant.

[0044] In addition, the upper edge 161 and the lower edge 162 also facilitate the formed side ear portion 15 to extend obliquely toward the rear of the co-pilot's head, so as to ensure that the head and neck protection area is trapezoidal.

[0045] In some embodiments, the first cutting piece 11 and the second cutting piece 12 further include a concave corner 141 . The concave corner 141 is located in the middle of the hollow peripheral edge 14 and is recessed into the hollow peripheral edge 14 along the direction of vehicle travel.

[0046] When the empty periphery 14 is folded and sewn to form the side ear portion 15, the fold of the empty periphery 14 is too sharp, and the concave corner 141 can prevent the cutting piece from reducing the sharpness of the side ear portion 15 at this concave corner 141. In addition, the concave corner 141 can facilitate the sewing of the empty periphery 14 at the fold.

[0047] In some embodiments, after the airbag body is inflated and deployed, as shown in FIG5 , the middle panel 13 also forms a front side 40 and a lower side 50 , wherein the front side 40 is used to abut against the automobile windshield 200 ; and the lower side 50 is used to abut against the display screen 300 on the automobile dashboard.

[0048] The front side surface 40 and the lower side surface 50 fit in contact with the fixing device in the vehicle, so that the position of the airbag body 10 can be relatively fixed when the airbag body 10 is inflated and deployed, thereby stabilizing the airbag.

[0049] In some embodiments, the first panel 11 and the second panel 12 both include a recessed groove 17 . After the middle panel 13 is sewn together with the first and second panels 11 and 12 , the lower side 50 of the middle panel 13 forms a recessed portion 18 adapted to the display screen 300 .

[0050] Therefore, after the first panel 11, the second panel 12 and the middle panel 13 are sewn together to form the airbag body 10, the airbag body 10 is inflated and deployed, as shown in Figure 5. The recessed portion 18 can avoid the display screen 300 to avoid crushing the display screen 300.

[0051] In some embodiments, the first panel 11 and / or the second panel 12 are provided with exhaust holes (not shown) to facilitate timely exhaust of the internal gas of the airbag body 10 after inflation and deployment, thereby preventing the airbag body 10 from inflating too quickly and causing too much damage to the co-pilot.

[0052] Based on the same inventive concept, the present disclosure provides a vehicle, as shown in Figures 4 and 5 , which includes at least a windshield 200, an instrument panel, a display screen 300 (also referred to as a central control screen), and the aforementioned passenger airbag 100. The vehicle can be a small car, bus, or truck, and in particular, an autonomous vehicle, such as an autonomous vehicle.

[0053] The display screen 300 may be a floating central control screen. With the development of vehicle technology, more and more functions tend to be integrated into the display screen 300. The display screen 300 may be basically placed in the horizontal middle part of the instrument panel to facilitate the driver's operation and viewing. Due to the trend of electric vehicles and future intelligent driving, in order to demonstrate high technology and provide an entertainment atmosphere, and to meet the user's demand for operating the display screen 300, the display screen 300 may become larger and larger. For example, it may be suspended above the styling surface of the instrument panel and extend as far as possible to the co-pilot side. Such a display screen 300 can not only provide assistance to the driver, but also provide entertainment facilities or other assistance to the co-pilot.

[0054] The gas generator 20 of the airbag is installed inside the instrument panel. The gas generator 20 is located below the instrument panel of the car and in front of the display screen 300. The gas generator 20 is connected to the airbag and is used to quickly inflate the airbag when the vehicle collides.

[0055] The airbag body 10 of the airbag can jump over the display screen 300 when inflating to avoid the display screen 300 being broken due to the impact force when the airbag body 10 is quickly inflated. After the airbag body 10 is inflated and deployed, the front side 40101 is used to contact the windshield 20010, and its rear side 30 and side ears 15 are used to contact the front passenger seat, which can provide normal protection for the person sitting in the front passenger seat, and its lower side 50 is used to contact the instrument panel. Among them, the recessed portion 18 of the airbag body 10 can avoid the display screen 300 to avoid crushing the display screen 300.

[0056] The specific manner of implementing the functions in the above embodiments has been described in detail in the embodiment of the passenger airbag 100 and will not be elaborated here.
