Description

Technical Field

[0001] The present disclosure relates to the field of safety technology, and more particularly, to an airbag, especially an airbag for a vehicle, and a combined system for the vehicle. Background Art

[0002] Airbags are widely used in modern vehicles as a safety protection measure when the vehicle encounters an emergency, such as a collision or rollover, wherein the airbag of the airbag can be inflated, expanded and deployed in a short time. The airbag can generate a large impact force during the expansion and deployment process. Typically, in order to ensure the safety of the vehicle occupants, no protruding objects are set in front of and above the airbag along the ejection direction, in the vicinity of the airbag, so as to prevent the ejected airbag from hitting the object and causing safety risks.

[0003] Typically, the passenger airbag of a vehicle is installed in the dashboard in front of the passenger seat along the vehicle's traveling direction, for example, above the glove box of the dashboard and below the styling surface of the dashboard.

[0004] With the development of vehicle technology, more and more functions tend to be integrated on electronic screens. For example, the central control screen of the dashboard can be basically placed in the horizontal middle part of the dashboard, which is convenient for the driver to operate and view. Due to the trend of electric vehicles and future intelligent driving, in order to show high technology and provide an entertainment atmosphere, and to meet the user's demand for electronic screen operation, the central control screen may become larger and larger. For example, it can be suspended above the styling surface of the dashboard and extend as far as possible to the co-pilot side. Such a central control screen can not only provide assistance to the driver, but also provide entertainment facilities or other assistance to the co-pilot.

[0005] In the prior art, when designing a central control screen, it is usually necessary to avoid the central control screen extending into the range of action of the passenger airbag. In other words, due to the presence of the passenger airbag, the width of the central control screen will be limited. In general, the central control screen can only extend to the boundary of the passenger airbag at most to prevent the passenger airbag from hitting the central control screen when it is detonated and deployed. For example, when a through-type screen is used, the airbag may impact the floating screen, causing splashes and causing harm to the occupants, or the airbag may not be deployed smoothly, making it difficult to provide appropriate protection. Summary of the invention

[0006] An object of the present disclosure is to provide an airbag and a combined system for a vehicle comprising such an airbag, wherein the airbag can have improved safety.

[0023] It is possible that the airbag can be formed into an accordion-like structure through multiple Z-shaped folds, which can realize the control of the deployment trajectory of the airbag, so that the airbag can jump over protruding objects such as a suspended central control screen in the early stage of deployment.

[0024] In some embodiments, the guide device may be made of a sheet that is folded in half and sewn at both sides into a cylindrical body after being folded in half.

[0025] In some embodiments, the guide device can be made of two sheets, one of which is sewn at its longitudinal edge to form a cylindrical body open at both ends, and the other sheet is sewn to the cylindrical body at one end of the cylindrical body to form the bottom of the cylindrical body.

[0026] In some embodiments, the guide device can be made of two side panels and a middle main panel, each side panel is sewn to a side edge of the middle main panel to form a tubular body, each side panel forms a side portion of the tubular body, and the middle main panel forms the other two opposite sides and the bottom of the tubular body.

[0051] Fig.15 Exploded view showing the airbag as a module. DETAILED DESCRIPTION

[0052] Figure 1 1 is a schematic cross-sectional view of an airbag 5 in an inflated and deployed state according to an embodiment of the present invention, wherein the cross section is defined by the central detonation point of the airbag and the ejection direction. The cross section may be a vertical plane substantially parallel to the longitudinal direction of the vehicle. Figure 1 The airbag 5 shown is designed as a passenger airbag. For example, it is also possible that the airbag 2 can be a driver airbag or a side airbag.

[0053] The vehicle may have a windshield 3 and an instrument panel 4. A central control screen 1 may be mounted on the instrument panel 4, and the central control screen 1 may protrude upward from the shaped surface of the instrument panel 4, for example, in the form of a floating screen. In the width direction of the vehicle, or in the horizontal direction transverse to the ejection direction of the passenger airbag, the central control screen 1 may extend all the way to the effective range of the passenger airbag. According to the level of knowledge in the prior art, the central control screen 1 protruding upward from the shaped surface of the instrument panel 4 can usually only extend to the side of the effective area of ​​the passenger airbag at most, so as to prevent the passenger airbag from colliding with the central control screen 1 when it is ejected, which may cause safety risks, such as the central control screen 1 may be shattered or the airbag 2 may not be deployed as required, so as to fail to provide appropriate safety protection for the occupant sitting in the passenger seat. The instrument panel 4 may have an installation space below its shaped surface for accommodating the airbag 5 as a mounting module.

[0054] The airbag 5 may include a housing, an airbag 2 and an inflator, which may be mounted on or connected to the housing. The airbag 2 may be accommodated in the housing in a folded state and may expand and unfold when inflated by the inflator until the airbag 2 is inflated. Figure 1 Typically, the inflator may be a pyrotechnic gas generator which is fixedly mounted centrally in the bottom of the housing of the airbag.

[0055] The airbag 2 may include a neck portion 11 and a main body portion 12. When the airbag 2 is inflated and deployed, a storage space 13 may be formed between the neck portion 11 and the main body portion 12. The storage space 13 is in a horizontal direction that is transverse to the ejection direction of the airbag 2 (eg, Figure 1 In the embodiment shown, the airbag 2 is passed through in the transverse direction of the vehicle. Figure 1 As can be seen from the cross-sectional view shown, the central control screen 1 can be at least partially accommodated in the accommodation space 13. In the horizontal direction mentioned above (for example, in the lateral direction of the vehicle), the central control screen 1 can occupy a portion of the width of the accommodation space 13, or can pass through the entire accommodation space 13.

[0056] According to the present invention, starting from the folded state of the airbag 2, during the expansion and deployment of the airbag 2, the main body 12 can at least cross from above an imaginary line extending in the horizontal direction (vehicle width direction) at a predetermined height in the accommodation space 13. The imaginary line can, for example, have a distance of less than 50 mm, such as 10 mm to 40 mm, such as 20 mm to 30 mm from the lowest vertex of the accommodation space 13. Advantageously, starting from the folded state of the airbag 2, during the expansion and deployment of the airbag 2, the main body 12 can at least cross from above the lowest vertex of the accommodation space 13. It is particularly advantageous that, starting from the folded state of the airbag 2, during the expansion and deployment of the airbag 2, the main body 12 can cross from above the half of the accommodation space 13 below the neck. Therefore, the airbag 2 will not collide with the central control screen 1 during the collision and deployment process.

[0057] Figure 2 It is used to make Figure 1 Schematic diagram of three sheets of airbag 2, specifically, airbag 2 may include two side sheets 2a, 2b and a middle main sheet 2c, the two side sheets 2a, 2b may be sewn to one of the two side edges of the main sheet 2c, and thus form airbag 2. In some embodiments not shown, the airbag 2 may also be composed of two side sheets sewn to each other, each side sheet may form a half of the airbag 2.

[0058] Figure 3 A plan view of a side panel according to one embodiment is shown, which can be used, for example, as a Figure 2 According to an advantageous embodiment, the side panels may have an elongated portion and a main body portion, and the length L2 of the elongated portion (the length of the neck 11) may be greater than or equal to Figure 1The length L1 shown. The length L1 can be the distance from the central detonation point to the midpoint of a vertical line from the upper edge of the central control screen 1 to the windshield 3. The central detonation point can be defined as the intersection of the central normal line of the airbag 5 as a module and the styling surface of the instrument panel 4. The length L2 can be the length of the center line from the root of the side piece to the transition part of the elongated part and the main body.

[0059] In such Figure 2 In the embodiment shown, the neck 11 of the airbag 2 can have a substantially rectangular cross section, such as a curved quadrilateral cross section, in the inflated and deployed state of the airbag 2. In the case where the airbag is composed of two side panels, the neck of the airbag can have a substantially circular or elliptical cross section.

[0060] Advantageously, in the inflated and deployed state of the airbag 2, the length L2 of the neck 11 of the airbag 2 may be at least 2 times, in particular at least 3 times, the equivalent radius of the neck. The equivalent radius may be defined as satisfying the following formula:

[0061]

[0062] Wherein, R represents the equivalent radius of the neck 11, L2 represents the length of the neck, and V represents the volume of the neck.

[0063] Figure 4 FIG. 2 is a schematic cross-sectional view of an airbag 5 according to a second embodiment of the present invention in an inflated and deployed state. Figure 1 The first embodiment shown differs mainly in that the airbag 5 comprises a flexible tension element 6. The airbag 5 can be otherwise identical or similar to the first embodiment, and reference can therefore be made to the description of the first embodiment. In the end region of the neck 11 of the airbag 2 adjacent to the main body 12, a flexible tension element 6 can be arranged inside the neck 11, which is designed to restrict the cross-sectional shape of the neck 11 in the inflated and deployed state of the airbag 2. The arrangement of the tension element 6 in the neck 11 can be particularly advantageous when the airbag 2 is composed of two side panels and has a circular or oval cross section in the region of the neck 11.

[0064] For example, the tension element 6 can be a mesh element having a plurality of joints at the edge, which are connected to the bag body of the airbag 2 in the area of ​​the neck 11. The mesh element can have a rectangular shape, for example. The tension element 6 can also be a cross-shaped element, which has four joints, which are connected to the bag body of the airbag 2 in the area of ​​the neck 11. In a particularly simple embodiment, Figure 4As shown, the pulling element 6 can be a drawstring, which is straightened when the airbag 2 is inflated and deployed. For example, the drawstring can extend approximately in a vertical plane in the neck 11 and be centrally arranged in the neck 11 in the horizontal direction. Advantageously, the drawstring can be approximately perpendicular to the windshield 3 and / or approximately coplanar with the central control screen 3 in the straightened state.

[0065] Refer to the following Figures 5 to 7 An airbag according to a third specific embodiment of the invention is described, wherein: Figure 5 This is a schematic diagram of the airbag during the expansion and deployment process. Figure 6 is a schematic diagram of an airbag in an inflated and deployed state, wherein the cross section is defined by the central detonation point of the airbag and the ejection direction. The cross section may be, for example, a vertical plane parallel to the longitudinal direction of the vehicle. Figure 6 In FIG. 1 , the guide device 10 is depicted by a dotted line. Figure 7 is a schematic diagram of the flexible guiding device 10 in a folded state.

[0066] In a third embodiment, the airbag may include a guide device, in particular a flexible guide device 10, which is designed to guide the airbag 2 during the inflation and deployment of the airbag. Figure 7 As shown, the guide device 10 can be flexible and foldable, wherein the folded airbag 2 is accommodated in the folded guide device 10, and the guide device can be converted from a folded state to an unfolded state, in which the guide device forms a guide sleeve. The guide device 10 can be made of the same or similar material as the airbag 2, for example. The inner end of the guide device 10 can be fixed on the housing of the airbag 5. First, the folded airbag 2 can be placed inside the guide device 10, and then the guide device 10 is folded, for example, in a Z-shape. The airbag 5 including the guide device 10 can be installed as a module, for example, in the installation space of the instrument panel 4. For example, more specifically, the airbag 2 can be folded first, and then the folded airbag 2 is wrapped and loaded into the guide device 10 configured as a guide sleeve, and then the guide device 10 is formed into a total package by several Z-folds, and then the total package can be loaded into the housing of the airbag 5. For example, the diameter, length and shape of the guide device 10 can be designed according to the installation positions of the windshield 3, the suspended central control screen 1 and the passenger airbag, so that its opening after deployment can pass over the upper edge of the suspended central control screen. Due to the existence of the guide device, the expansion and deployment process of the airbag 2 can be controlled, so that the airbag 2 will not impact the suspended central control screen 1 during the expansion and deployment process.

[0067] When the inflator of the airbag 5 is activated, gas is quickly filled into the airbag 2. The airbag 2 during the expansion and deployment process can convert the guide device 10 from a folded state to an deployed state. The guide device 10 can extend over the central control screen 1 in the deployed state, and the airbag 2 guided in the guide device 10 can pass over the central control screen 1 until it reaches the position as shown in FIG. Figure 6 Advantageously, the guide sleeve can have the same extension direction as the neck 11 of the airbag 2, and the guide sleeve can be tightly wrapped around the neck 11 when the airbag 2 is inflated and deployed. When the airbag 2 is filled with gas and has thus inflated and deployed, the flexible guide device 10 can also constrain the airbag 2 to reduce the squeezing of the airbag 2 on the central control screen 1.

[0068] In some embodiments not shown, the guide device may not extend to and over the central control screen 1 in the deployed state, but the outlet of the guide device is designed in terms of its height and outlet orientation so that the main body 12 ejected from the outlet can pass over the central control screen 1. In general, the guide device 10 can define an ejection trajectory for the airbag 2, and the ejection trajectory can ensure that the airbag 2 will not touch a predetermined protruding object during the expansion and deployment process.

[0069] Figures 8 to 10 In each case, an embodiment for producing a guide device 10 is shown.

[0070] like Figure 8 As shown, the guide device 10 can be made of a cut sheet 23 having a central hole 25. The sheet 23 can be folded in half along a folding line 24 and then sewn on both sides to form a cylindrical body having a bottom at one end and an opening at the other end, wherein the bottom has a central hole 25 for fixing the guide device 10 on the housing of the airbag 5.

[0071] like Fig. 9 As shown, the guide device 10 can be made of two cut sheets 26 and 27, wherein the sheet 26 can be sewn at its two longitudinal edges to form a cylindrical body open at both ends, and then the sheet 27 is sewn to one end of the sewn sheet 26 as a bottom with a central hole 25.

[0072] like Fig.10 As shown, the guide device 10 can be made of three cut sheets, namely two side sheets 28 and a central main sheet 29. The central main sheet 29 has a central hole 25, which also serves as a fixing measure for the bottom of the final cylindrical body on the housing of the airbag.

[0073] Fig.11 show Fig.10A variant in which drawstrings 31, 32 are provided on the inner side of the bag of the guide device 10, for example on the opposite sides of the bag formed by the middle main piece 29. These drawstrings can facilitate the unfolding process of the guide device 10 and the form stability after unfolding.

[0074] Refer to the following Figure 12 to Figure 14 An airbag according to a fourth specific embodiment of the present invention will be described. Fig.12 The airbag 2 of the airbag is shown in a folded state, and Fig.13 The airbag 2 of an airbag is shown during inflation and deployment, wherein the cross section is defined by the central bursting point of the airbag and the ejection direction. Fig.14 The air bag 2 is shown in a folded form.

[0075] In this embodiment, the airbag 2 can be folded to allow the airbag 2 to pass over the central control screen 1 during the expansion and deployment process, thereby avoiding the collision of the airbag 2 with the central control screen 1 during the expansion and deployment process and the safety risks caused thereby. The airbag 2 can include multiple Z-shaped folds (such as Fig.14 Advantageously, the airbag 2 may include multiple Z-shaped folds in the neck 11 and at least in a section of the main body 12 adjacent to the neck 11 in the folded state. For example, the airbag 2 may include only Z-shaped folds in the folded state, such as Fig.14 As an alternative, the air bag 2 may also be located in a section of the main body 12 away from the neck 11 (eg Fig.14 The device is folded and rolled in a manner as indicated by the mark 22 in the figure.

[0076] The airbag 2 is repeatedly folded in Z-shape to form an accordion-like structure. This structure can realize that in the early stage after detonation, the force condition of the folded airbag can be similar to that of a spring, so that the folded airbag can quickly jump upward during the expansion and unfolding process, thereby smoothly climbing over a protruding object such as the suspended central control screen 1.

[0077] In some embodiments not shown, the airbags according to the above embodiments can also be used as passenger airbags in the absence of the central control screen 1. When objects are accidentally placed in the dashboard area in front of the passenger, such airbags can be beneficial to the safety of the vehicle occupants when they are popped out.

[0078] In some embodiments not shown, the airbags according to the above embodiments can also be used as driver airbags. When the autonomous intelligent vehicle is not equipped with a steering wheel, the driver airbag can especially be an airbag according to any of the above embodiments.

[0079] Fig.15 An exploded view of an airbag as a module is shown. The aforementioned embodiments of the airbag may have the same or similar configurations. Fig.15 The safety airbag shown may include a dust cover 33, a folding bag 34, a retaining ring 35, a housing 36, a gas generator 37 and a fastener 38. The folding bag 34 may be fixed in the housing 36 by the retaining ring 35, and the housing 36 may be fixed in the installation space in the instrument panel by the fastener 38. The folding bag 34 may include a folded airbag 2 and a flexible guide device 10 that wraps the airbag 2 and is also folded. The airbag 2 and the guide device 10 may be configured the same or similarly as in the aforementioned embodiment, for example. The material of the guide device 10 may be the same or similar to that of the airbag 2, or other flexible and deformable materials may also be used.
