[0002] Airbags can improve the safety of passengers in cars. They can provide additional protection for passengers by quickly inflating when the vehicle collides. Airbags in related technologies usually include a large airbag that is similar to a bag or a ball in the inflated state. When the car collides, the airbag is filled with gas and becomes a large spherical structure, thereby providing cushioning protection for the passengers.

[0003] Related Technology: This type of large-volume spherical airbag has a relatively large inner cavity volume, so a large amount of gunpowder is required in the propellant bag when inflating the airbag, which increases the cost of the airbag. Moreover, the gunpowder triggering system required when the amount of gunpowder is large is more complex and more powerful, further increasing the manufacturing cost of the airbag and the car. Utility Model Content

[0004] The present application provides an airbag and a car. The airbag can achieve effective cushioning and collision prevention through a smaller inner cavity volume, thereby reducing the amount of gunpowder required for the propellant bag when inflating the airbag, reducing the cost of the airbag, and reducing the complexity of the gunpowder triggering system, further reducing the manufacturing cost of the airbag and the car. The specific scheme is as follows:

[0005] In a first aspect, an embodiment of the present application provides a safety airbag, comprising: a hook-shaped airbag, wherein the hook-shaped airbag is hook-shaped when inflated and deployed, and a connecting cloth piece is connected between the hook end of the hook-shaped airbag and an opposite airbag surface, wherein the opposite airbag surface is an airbag surface of the hook-shaped airbag opposite to the hook end; when the hook-shaped airbag is in the inflated and deployed state, the connecting cloth piece is tightened by the hook end and the opposite airbag surface, so that the hook end is tightened and positioned relative to the opposite airbag surface by the connecting cloth piece;

[0006] When the hook-shaped airbag is installed on the airbag installation position and is in an inflated and deployed state, the hook portion of the hook-shaped airbag is opposite to the head and chest of the occupant to be protected, so as to provide buffering protection to the head and chest of the occupant to be protected.

[0007] Optionally, the hook-shaped airbag is used to be installed in an airbag installation position of a car in a barbed hook shape when in an inflated and deployed state.

[0008] Optionally, the hook-shaped airbag comprises a hook portion and a handle portion, the handle portion is connected to a connecting end of the hook portion, and the handle portion is used to be installed on the airbag installation position;

[0009] When the handle is installed on the airbag installation position, the hook portion is located above the handle, so that the hook-shaped airbag is in a barb shape.

[0010] Optionally, the airbag is used to provide cushioning protection for occupants in rear seats, and the airbag mounting position is arranged on the backrest of a row of seats in front of the rear seats.

[0011] Optionally, the handle extends in a direction away from the hook end, and the hook-shaped airbag is used to be installed on the airbag installation position with the hook end facing the occupant to be protected;

[0012] Alternatively, the handle extends in an offset direction close to the hook end, and the hook-shaped air bag is used to be installed on the air bag installation position with the hook end facing the backrest of the front row of seats.

[0013] Optionally, the airbag installation position is located at the lower part of the backrest of the front row of seats, and the position of the handle adjacent to the lower end is used for installation on the airbag installation position.

[0014] Optionally, a gas generator for inflating the airbag is fixedly disposed in the handle, and the gas generator is also used to be installed on the airbag installation position, so that the handle is installed on the airbag installation position through the gas generator.

[0015] Optionally, when the safety airbag is installed on the airbag installation position and is in an inflated and deployed state, the handle is used to be opposite to the legs of the rear occupants to provide cushioning protection for the legs.

[0016] Optionally, when the hook-shaped airbag is used to be installed on the airbag mounting position with the hook end facing the backrest of the front row of seats, the handle is bent in the direction close to the hook end and then extended in the direction close to the hook end. The bent part of the handle is used to be opposite to the knees of the rear passenger when he is sitting, so as to provide cushioning protection for the knees.

[0017] In a second aspect, an embodiment of the present application further provides a car, wherein an airbag installation position is provided in the car, and the airbag installation position is installed with the safety airbag as described in any one of the first aspects;

[0018] When the safety airbag is in an inflated and deployed state, the hook portion of the safety airbag is opposite to the head and chest of the occupant to be protected, so as to provide buffering protection to the head and chest of the occupant to be protected.

[0019] Compared with the prior art, this application has the following advantages:

[0020] The safety airbag provided by the present application includes a hook-shaped airbag, which is hook-shaped when in the inflated and deployed state. A connecting cloth piece is connected between the hook end of the hook-shaped airbag and the relative airbag surface, and the relative airbag surface is the airbag surface of the hook-shaped airbag opposite to the hook end. When the hook-shaped airbag is in the inflated and deployed state, the connecting cloth piece can be tightened by the hook end and the relative airbag surface. Therefore, the hook end can be tightened and positioned relative to the relative airbag surface through the connecting cloth piece, so that the hook end of the hook-shaped airbag and the relative airbag surface are tightened and positioned into a stable hook shape by the connecting cloth piece, and are not prone to excessive deployment in the inflated and deployed state, so as to maintain a stable hook shape and provide effective buffering protection for the occupant. The hook-shaped airbag is used to be installed in the airbag mounting position of the car in a hook shape when in the inflated and deployed state. When the hook-shaped airbag is installed on the airbag mounting position and is in the inflated and deployed state, the hook part of the hook-shaped airbag is opposite to the head and chest of the occupant to be protected. Since the hook-shaped airbag is filled with gas and has a hollow part in the middle, the cushioning performance can be further improved, thereby providing effective cushioning protection for the head and chest of the occupant to be protected.

[0021] The safety airbag in the embodiment of the present application is a hook-shaped airbag. Since the hook-shaped airbag has a hollow structure in the middle, there is no need to inflate the hollow structure. Only the hook-shaped airbag needs to be inflated. Compared with large-volume bag-shaped or spherical airbags, the inner cavity volume of the airbag can be greatly reduced. Therefore, the amount of gunpowder required for the propellant bag when inflating the airbag can be reduced, thereby reducing the cost of the airbag and the complexity of the gunpowder triggering system, further reducing the manufacturing cost of the airbag and the automobile, and achieving effective cushioning and collision prevention through a smaller inner cavity volume.

[0034] Airbags can improve the safety of passengers in cars. They can provide additional protection for passengers by quickly inflating when the vehicle collides. Airbags in related technologies usually include a large airbag that is similar to a bag or a ball in the inflated state. When the car collides, the airbag is filled with gas and becomes a large spherical structure, thereby providing cushioning protection for the passengers.

[0035] Related Technology: This type of large-volume spherical airbag has a relatively large inner cavity volume, so a large amount of gunpowder is required in the propellant bag when inflating the airbag, which increases the cost of the airbag. Moreover, the gunpowder triggering system required when the amount of gunpowder is large is more complex and more powerful, further increasing the manufacturing cost of the airbag and the car.

[0036] Based on this, the present application provides an airbag and a car. The provided airbag can achieve effective cushioning and collision prevention through a smaller inner cavity volume, thereby reducing the amount of gunpowder required for the propellant bag when inflating the airbag, reducing the cost of the airbag, and can also reduce the complexity of the gunpowder triggering system, further reducing the manufacturing cost of the airbag and the car.

[0037] Next, the airbag provided by the present application will be described in detail with reference to the accompanying drawings.

[0038] like Figures 1 to 5 As shown, the safety airbag provided by the embodiment of the present application includes a hook-shaped airbag 11, which is hook-shaped when inflated and deployed, and a connecting cloth piece 12 is connected between the hook end of the hook-shaped airbag 11 and the opposite airbag surface, and the opposite airbag surface is the airbag surface of the hook-shaped airbag 11 opposite to the hook end; when the hook-shaped airbag 11 is in the inflated and deployed state, the connecting cloth piece 12 is tightened by the hook end and the opposite airbag surface, so that the hook end is tightened and positioned relative to the opposite airbag surface through the connecting cloth piece 12;

[0039] When the hook-shaped airbag 11 is installed on the airbag installation position and is in an inflated and deployed state, the hook portion 11a of the hook-shaped airbag 11 is opposite to the head and chest of the occupant to be protected, so as to provide cushioning protection to the head and chest of the occupant to be protected.

[0040] The airbag provided in the present application can be installed on the front side of the first row of seats to provide cushioning protection for the first row of passengers. For example, it can be installed in the center of the driver's steering wheel or in front of the steering wheel, or it can be installed in the front of the dashboard of the car near the front passenger seat, or it can be installed inside the door to protect the side of the passengers. This application does not specifically limit it. Correspondingly, when the airbag is used to provide cushioning protection for the passengers on the first row of seats, the airbag installation position for installing the airbag can be set at at least one of the following positions: the center of the steering wheel, the front of the steering wheel, the front of the dashboard near the front passenger seat, and the inside of the door.

[0041] The airbag provided in the present application can also be installed on the backrest of the front seat to provide cushioning protection for the occupants on the rear seat 30, for example, it can be installed on the rear side of the backrest of the front seat. It can be understood that when the car includes three or more rows of seats, the rear seat 30 can be the second row of seats, the third row of seats, etc., and the front seat refers to the row of seats 20 in front of the rear seat 30. Correspondingly, when the airbag is used to provide cushioning protection for the occupants on the rear seat 30, the airbag installation position for installing the airbag can be set on the backrest of the row of seats 20 in front of the rear seat 30.

[0042] like Figures 2 to 5 As shown, the hook-shaped airbag 11 can be installed in the airbag installation position of the car in a hook shape when inflated and deployed. The hook-shaped airbag 11 is in a hook shape, that is, the hook opening of the hook-shaped airbag 11 faces downward. This method can more effectively protect the head of the member, and the hook-shaped airbag is more convenient to set the handle 11b downward, so as to more conveniently cushion and protect the legs of the rear passengers. The hook-shaped airbag 11 can also be installed in the airbag installation position of the car in a hook shape when inflated and deployed. This method can also effectively protect the rear passengers. Those skilled in the art can flexibly set it according to actual conditions.

[0043] The hook-shaped airbag 11 may include a hook portion 11a, which is a U-shaped structure when inflated and deployed. That is, the hook-shaped airbag 11 may be a U-shaped structure when deployed. The hook-shaped airbag 11 including only the hook portion 11a can meet the design requirements of protecting the head and chest of the occupant, and has a simple structure and a small airbag cavity volume, which can well reduce the amount of gunpowder in the propellant bag required for inflation. When the hook-shaped airbag 11 only includes the hook portion 11a, the hook portion 11a can be installed on the airbag installation position, for example, the outer side surface of the hook portion 11a is connected to the airbag installation position by sewing, bonding, bolting, etc.

[0044] Alternatively, if Figure 1As shown, the hook-shaped airbag 11 may include a hook portion 11a and a handle portion 11b, wherein the handle portion 11b is connected to the connecting end of the hook portion 11a, and the handle portion 11b is used to be installed on the airbag installation position. The hook portion 11a includes a hook end and a connecting end, wherein the connecting end is an end of the hook portion 11a opposite to the hook end. The handle portion 11b may be a straight handle shape, a curved handle shape, or other handle shapes. The structure of the handle portion 11b may be flexibly set according to the position structure installed on the car, which is not specifically limited in this application. The handle portion 11b is used to facilitate the installation of the safety airbag. When the handle portion 11b is installed on the airbag installation position, the hook portion 11a is located above the handle portion 11b, so that the hook-shaped airbag 11 is in the shape of a barb. The handle portion 11b may be connected to the airbag installation position by sewing, bonding, bolting, etc. When the airbag is installed on the backrest of the front row seat 20 to protect the occupants on the rear seat 30, the handle 11b provided below can effectively protect the legs of the rear occupants, thereby improving the protection effectiveness.

[0045] The connecting cloth piece 12 can be a polyester fiber cloth piece or a nylon cloth piece, or other cloth pieces, which is not specifically limited in this application. The anti-collision cloth piece can be connected to the hook-shaped airbag 11 by sewing, bonding, integral molding, etc., and the specific connection method is not limited. The relative airbag surface can be the airbag surface of the hook-shaped airbag 11 that is directly opposite to the hook end, or it can be the airbag surface that is opposite to the hook end. The connecting cloth piece 12 can tighten and position the hook end with the opposite side, and the specific connection position and connection method are not limited.

[0046] like Figure 1 As shown, the connecting cloth piece 12 can be a rectangular cloth piece that extends as a whole along the width direction of the hook-shaped air bag 11, so that the air bag can be reliably tightened and positioned by the cloth piece that extends as a whole. Optionally, the connecting cloth piece 12 can also be a thin and long cloth piece, and the thin and long cloth piece can include two pieces, which are respectively connected to the two ends of the width direction of the hook-shaped air bag 11, so as to achieve the tightening and positioning of the hook-shaped air bag 11, and can also save the amount of cloth pieces used. The thin and long cloth piece can also include one piece, and the thin and long cloth piece can be connected to the middle of the width direction of the hook-shaped air bag 11, so that the tightening and positioning of the hook-shaped air bag 11 can also be achieved. Those skilled in the art can flexibly set the connection position, shape and number of the connecting cloth piece 12, and this application does not specifically limit it.

[0047] In a specific embodiment, Figures 1 to 3As shown, the handle 11b can be offset and extended in a direction away from the hook end, and the hook-shaped airbag 11 is used to be installed on the airbag installation position in a manner that the hook end faces the occupant to be protected. In this embodiment, the airbag installation position is the backrest of the front row seat 20. When the handle 11b is offset and extended in a direction away from the hook end, the handle 11b can better fit the backrest of the front row seat 20, so that the handle 11b is better fitted and installed on the backrest of the front row seat 20, which is convenient for the installation of the safety airbag and has good installation stability.

[0048] In another specific embodiment, Figure 4 , Figure 5 As shown, the handle 11b can be offset and extended in a direction close to the hook end, and the hook-shaped airbag 11 is used to be installed on the airbag installation position in a manner that the hook end faces the backrest of the front row seat 20. In this embodiment, since the hook end is to face the backrest of the front row seat 20, and the handle 11b is connected to the connecting end of the hook portion 11a, in order to enable the handle 11b to contact and be installed on the backrest of the front row seat 20, the handle 11b can be offset and extended in a direction close to the hook end, so as to extend to the backrest of the front row seat 20 for installation and fixation. In this embodiment, the hook end faces the backrest of the front row seat 20. Since the hook end is not connected to the handle 11b, a certain amount of free space can be reserved for the rear side of the front row seat 20, so that a display screen, a tool box or other functional devices can be installed on the front row seat 20.

[0049] In a specific embodiment, Figures 2 to 6 As shown, the airbag installation position can be located at the lower part of the front row of seats 20, and the position adjacent to the lower end of the handle 11b is used to be installed on the airbag installation position. In this way, the handle 11b of the hook-shaped airbag 11 can be extended from bottom to top to a position where the hook 11a is opposite to the head and chest of the occupant to be protected, and the handle 11b located at the bottom can be opposite to the legs of the rear row occupant to provide cushioning protection for the legs.

[0050] In a specific embodiment, a gas generator 13 can be fixedly provided in the handle 11b. The gas generator 13 is used to inflate the safety airbag, specifically to inflate the hook-shaped airbag 11, so that the above-mentioned hook-shaped airbag 11 is expanded by inflation through the gas generator 13. The gas generator 13 is also used to be installed on the above-mentioned airbag mounting position, so that the hook-shaped airbag 11 is installed on the airbag mounting position through the gas generator 13.

[0051] The gas generator 13 may include a propellant charge, an ignition device, and a generator housing. The propellant charge contains chemical substances of the gas generator 13, which are used to quickly generate a large amount of gas when a vehicle collides, so as to quickly inflate the airbag. The ignition device is used to ignite the propellant charge to start a chemical reaction to generate gas. The ignition device may be an electronic trigger, which is controlled by an electronic control unit of the vehicle. The propellant charge and the ignition device are arranged in the generator housing.

[0052] The generator housing of the gas generator 13 is fixedly connected to the hook-shaped airbag 11 , and the generator housing can be installed on the airbag installation position by bolt connection, clamping, etc.

[0053] In the embodiment of the present application, when the hook-shaped airbag 11 is installed on the airbag installation position with the hook end facing the occupant to be protected, the handle 11b of the hook-shaped airbag 11 and the transitional bend of the hook portion 11a can be used to face the knees of the rear occupant when sitting, so as to provide cushioning protection for the knees. When the hook-shaped airbag 11 is installed on the airbag installation position with the hook end facing the backrest of the front row seat 20, the handle 11b can be bent in the direction close to the hook end and then extended in the direction close to the hook end, and the bent portion of the handle 11b is used to face the knees of the rear occupant when sitting, so as to provide cushioning protection for the knees.

[0054] The safety airbag provided by the present application includes a hook-shaped airbag 11. The hook-shaped airbag 11 is in a hook shape when in the inflated and deployed state. A connecting cloth piece 12 is connected between the hook end of the hook-shaped airbag 11 and the relative airbag surface. The relative airbag surface is the airbag surface of the hook-shaped airbag 11 opposite to the hook end. When the hook-shaped airbag 11 is in the inflated and deployed state, the connecting cloth piece 12 can be tightened by the hook end and the relative airbag surface. Therefore, the hook end can be tightened and positioned relative to the relative airbag surface through the connecting cloth piece 12, so that the hook end of the hook-shaped airbag 11 and the relative airbag surface are tightened and positioned into a stable hook shape by the connecting cloth piece 12 and are not prone to transitional deployment in the inflated and deployed state, so as to maintain a stable hook shape and provide effective buffering protection for the occupant. The hook-shaped airbag 11 is used to be installed in the airbag installation position of the automobile in a barbed hook shape when in the inflated and deployed state, such as Figures 2 to 5 As shown in FIG. 1 , when the hook-shaped airbag 11 is installed on the airbag installation position and is in the inflated and deployed state, the hook portion 11a of the hook-shaped airbag 11 is opposite to the head and chest of the occupant to be protected. Since the hook-shaped airbag 11 is filled with gas and the middle of the hook-shaped airbag 11 has a hollow portion, the cushioning performance can be further improved, so that the head and chest of the occupant to be protected can be effectively cushioned and protected. Figure 3 , Figure 5 As shown, when a collision occurs, the hook portion 11a can effectively protect the head and chest of the occupant.

[0055] The safety airbag of the embodiment of the present application is a hook-shaped airbag 11. Since the hook-shaped airbag 11 has a hollow structure in the middle, there is no need to inflate the hollow structure. Only the hook-shaped airbag 11 needs to be inflated. Compared with a large-volume bag-shaped or spherical airbag, the inner cavity volume of the airbag can be greatly reduced. Therefore, the amount of gunpowder required for the propellant bag when inflating the airbag can be reduced, thereby reducing the cost of the airbag and the complexity of the gunpowder triggering system, further reducing the manufacturing cost of the airbag and the automobile, and achieving effective cushioning and collision prevention through a smaller inner cavity volume.

[0056] The embodiment of the present application further provides a car, wherein a car installation position is provided in the car, and the airbag installation position is installed with a safety airbag 10 as described in any one of the above embodiments. Figures 2 to 5 As shown, when the airbag 10 is in the inflated and deployed state, the hook portion 11 a of the airbag 10 is opposite to the head and chest of the occupant to be protected, so as to provide buffering protection to the head and chest of the occupant to be protected.

[0057] The airbag installation position may include at least one of the following positions: the center of the steering wheel, the front of the steering wheel, the front of the instrument panel near the passenger seat, the inside of the door, and the backrest of the front row of seats 20 .

[0058] Alternatively, if Figures 2 to 5 As shown, multiple rows of seats can be provided in the car, and the airbag installation position can be provided on the backrest of the row of seats 20 in front of the protection seat, specifically, it can be provided on the backrest frame of the row of seats 20 in front of the protection seat. The protection seat is the seat protected by the airbag 10. In this way, the airbag 10 provided by the present application can be installed on the backrest of the front row of seats 20 to provide buffering protection for the rear passengers.

[0059] Optionally, the hook-shaped airbag 11 can be installed in a vehicle airbag installation position in a barb shape when in the inflated and deployed state.

[0060] Optionally, the hook-shaped airbag 11 includes a hook portion 11a and a handle portion 11b, the handle portion 11b is connected to the connecting end of the hook portion 11a, the handle portion 11b is installed on the airbag installation position, and the hook portion 11a is located above the handle portion 11b, so that the hook-shaped airbag 11 is in the shape of a barb.

[0061] Alternatively, if Figure 2 , Figure 3 As shown, the handle 11 b extends in a direction away from the hook end, and the hook-shaped airbag 11 is installed on the airbag installation position with the hook end facing the occupant to be protected.

[0062] Alternatively, if Figure 4 , Figure 5 As shown, the handle 11 b extends in a direction close to the hook end, and the hook-shaped airbag 11 is installed on the airbag installation position with the hook end facing the backrest of the front row of seats 20.

[0063] Alternatively, if Figures 2 to 5 As shown, a gas generator 13 for inflating the airbag 10 may be fixedly disposed in the handle 11 b , and the gas generator 13 is installed on the airbag installation position, so that the handle 11 b is installed on the airbag installation position through the gas generator 13 .

[0064] Optionally, the handle 11b is used to face the legs of rear passengers to provide cushioning protection for the legs.

[0065] Optionally, when the hook end of the hook-shaped airbag 11 is facing the backrest of the front row of seats 20, the handle 11b is bent toward the direction close to the hook end and then extended in an offset direction close to the hook end. The bent portion of the handle 11b is opposite to the knees of the rear passenger when he is sitting, so as to provide cushioning protection for the knees.

[0066] Optionally, a mounting bracket can be provided on the seat back frame of the front row of seats 20, and the gas generator 13 of the airbag 10 can be fixedly mounted on the mounting bracket. For example, the generator housing of the gas generator 13 is fixed to the mounting bracket by bolting, clamping, riveting, etc. The provision of the mounting bracket makes it easier to install the airbag 10 on the backrest of the front row of seats.

[0067] Alternatively, if Figures 2 to 5 As shown, the airbag installation position can be set at the lower part of the backrest of the front row seat 20, so that the handle 11b of the airbag 10 is installed under the backrest of the front row seat 20, and the position adjacent to the lower end of the handle 11b is installed on the airbag installation position, so that the handle 11b for installing the airbag can extend from bottom to top until the hook portion 11a is consistent with the head and chest height of the rear occupant. In this way, the head and chest of the rear occupant can be effectively protected, and the legs and knees can also be effectively cushioned and protected by the handle 11b.

[0068] Alternatively, if Figure 6 , Figure 7As shown, an isolation sheet 50 may be provided on the frame of the backrest of the front row seat 20, and the isolation sheet 50 may also be understood as a guide sheet. The airbag 10 is installed on the side of the isolation sheet 50 facing the rear row seat 30 (i.e., the protective seat), and the side of the isolation sheet 50 facing away from the rear row seat 30 is used to install components in the backrest, and the components in the backrest may include, for example, sensors, cables, etc., but are not limited thereto. The isolation sheet 50 may be a piece of cloth, a plastic sheet, etc., or other materials with isolation and protection functions, which are not specifically limited in this application. The isolation sheet 50 may be connected to the frame of the seat back by threaded connection, clamping connection, or gas connection. By providing the isolation sheet 50, this embodiment can better prevent the phenomenon that the airbag is scratched and damaged during the detonation of the gas generator 13 to inflate the airbag, and can also better prevent damage to components such as the wiring harness in the seat back during the detonation process.

[0069] It is understandable that, when no collision occurs, the airbag 10 is folded and placed in the backrest of the front row of seats 20, and an airbag shielding plate may be provided on the backrest of the front row of seats 20, and the airbag shielding plate is used to shield the airbag 10. When a collision occurs, the electronic control unit of the automobile controls the gas generator 13 of the airbag 10 to inflate each airbag of the airbag 10 so that the airbag 10 is inflated and deployed, so as to open the airbag shielding plate from the backrest of the front row of seats 20 so that the airbag 10 pops out to protect the occupants.

[0070] The specific implementation manner of the safety airbag 10 in this automobile embodiment and the installation method of the airbag on the automobile are similar to the safety airbag 10 in the above-mentioned embodiment. Please refer to the relevant contents of the above-mentioned embodiment for details, and no unnecessary details will be given here.

[0071] It should be noted that, although several structures, components or units for realizing related functions are mentioned in the above detailed description, such division is not mandatory.
