[0037] Furthermore, in the utility model, an inner pulling mechanism 4 is provided in the inflation cavity 1-1. The setting of the inner pulling mechanism 4 is mainly used for the connection between the two side walls of the airbag body 1. By controlling the strength of the inner pulling mechanism 4, the inflation thickness of the airbag body 1 for the regional cavity can be controlled; specifically, in the utility model, the inner pulling mechanism 4 includes an inner pulling belt 3, and the two ends of the inner pulling belt 3 are respectively attached to the inner walls on the opposite sides of the airbag body 1; the inner pulling belt 3 mainly plays a limiting role, limiting the interval between the inner walls connected at the two ends of the inner pulling belt 3, so that the regional expansion thickness of the airbag body 1 can be controlled.

[0038] During actual connection, the inner pulling mechanism 4 includes a plurality of inner pulling straps 3 , and generally two inner pulling straps 3 may be provided. Based on such a setting, it is convenient to control the expansion thickness corresponding to the width of the airbag body 1 .

[0041] At the same time, the external pulling mechanism 6 in the utility model includes two external pulling straps 5, one of which is connected to the fastening part, and the other end of which extends toward the side of the bonding cloth 2 on the airbag body 1; one end of the other external pulling strap 5 is connected to the fastening part, and the other end of which extends toward the edge area of ​​the airbag body 1; based on such a setting, the external pulling mechanism 6 has different extension directions on the airbag body 1, which can play a better shaping role, that is, it can ensure to a certain extent that the distal airbag can maintain a stable vertical upright state after inflation.

[0042] Furthermore, in the utility model, an air guide cloth 7 is provided in the airbag main body 1; the air guide cloth 7 is covered on the gas generating part, and an exhaust hole 12 is provided on the air guide cloth 7; the provision of the air guide cloth 7 and the exhaust hole 12 facilitates the control of the flow direction of the gas generated by the gas generating part, and facilitates the control of the inflation speed of the airbag main body 1 as needed.

[0043] In addition, in the utility model, two exhaust holes 12 are provided on the air guide cloth 7, and the two exhaust holes 12 are located on the side away from the gas generating part; the orientations of adjacent exhaust holes 12 are different; based on such a setting, the exhaust holes 12 are set in different directions, so that the airbag body 1 can have different inflation directions. By limiting the air outlet direction in actual use, the expansion and opening of the airbag body 1 can be quickly achieved.

[0044] Furthermore, in the present invention, the airbag body 1 is sewn from an integral main cloth; such a configuration greatly ensures the integrity of the airbag body 1 .

[0045] Furthermore, in the utility model, the fastening part includes a stud arranged on the airbag body 1; the setting of the fastening part facilitates the connection between the airbag body 1 and the main driver's seat, and at the same time, the setting of the stud facilitates the connection between the airbag body 1 and the main driver's seat, and an installation bolt hole 8 is provided on the airbag body 1, and the subsequent stud passes through the installation bolt hole 8 to be connected with the main driver's seat.

[0046] A vehicle assembly includes a driver's seat and a passenger's seat; a distal airbag for a vehicle is arranged on the driver's seat near the passenger's seat; when a side collision occurs in the vehicle, a gas generator 11 in the distal airbag disclosed in the utility model starts to inflate, and air flows into the cavity from two outlet directions, the upper part and the lower part of the air guide cloth 7; the air flow quickly fills the airbag, the inner drawstring 3 is tightened to restrain the bag shape, and the outer drawstring 5 is also quickly tightened, and the deployment direction of the distal airbag remains in a stable vertical upright state in the filled state; the distal airbag can effectively prevent the head and neck of the driver and passenger from colliding with each other, reduce the Y-direction offset of the occupants' heads, and reduce the damage value of their head, neck and chest.

[0047] specific:

[0048] The utility model discloses a vehicle distal airbag; the distal airbag disclosed in the utility model can maintain a stable vertical state between the main and front passenger seats after inflation through a unique single-cavity distal airbag envelope shape and internal structure, thereby providing reliable Y-direction support for the head, neck and torso of the occupant, better blocking the Y-direction deviation of the occupant's head, and avoiding mutual collision between occupants, thereby reducing the risk of secondary injury to the occupants inside the car after a collision.

[0049] It mainly includes a piece of airbag main cloth, two inner drawstrings 3, two outer drawstrings 5, a piece of air guide cloth 7, and a gas generator 11.

[0050] Furthermore, the main fabric of the air bag is in the shape of an apple cross section, symmetrical along the central axis, has two mounting holes at the bottom of the main fabric, and has a semicircular closed area in the middle of the main fabric.

[0051] The gas generator 11 is placed vertically through the bottom and the studs are passed through the two mounting holes of the main cloth.

[0052] The two inner drawstrings 3 are rectangular in shape and are arranged on the upper part of the airbag. The long straight sides of the inner drawstrings 3 are sewn together with the left and right sides of the main fabric symmetrically along the central axis.

[0053] The two outer pull belts 5 are in the shape of thin and long strips, one end of the outer pull belt 5 is connected to the lower stud of the gas generator 11, and the other end is sewn together with the marking circle on the main cloth respectively.

[0054] The bottom of the air guide cloth 7 has two mounting holes for cooperating with the studs of the gas generator 11. At the same time, the air guide cloth 7 is sewn together along the left and right symmetrical sides of the central axis, leaving exhaust holes 12 at the upper and lower ends respectively.

[0055] Beneficial results of the utility model: when a vehicle has a side collision, a gas generator 11 of a vehicle side collision occupant protection remote airbag starts to inflate, and air flows into the cavity from the two outlet directions of the upper and lower parts of the air guide cloth 7 at the same time.

[0056] The airflow quickly fills the airbag, the inner drawstring is tightened to restrain the bag shape, and the outer drawstring is also quickly tightened to restrict the deployment direction of the airbag and maintain a stable vertical upright state when filled. The distal airbag can effectively prevent the head and neck of the driver and the co-driver from colliding with each other, reduce the Y-direction deviation of the occupant's head, and reduce the damage value of the head, neck and chest.

[0057] like Figure 1-Figure 3 As shown, a vehicle side collision occupant protection distal airbag body 1 structure is composed of a piece of airbag main cloth ① sewn along the boundary to form a closed cavity.

[0058] Inner drawstrings 3 are arranged on the upper part of the airbag, and the long straight sides of the inner drawstrings 3 are sewn together with the left and right sides of the main fabric of the airbag symmetrically along the central axis, so as to reasonably control the thickness of the inflation cavity of the upper part of the distal airbag.

[0059] In order to effectively distribute the volume and thickness of the inflation cavity, a sealing area in the middle of the distal airbag adopts a bonding part 2-1. The bonding cloth 2 in the bonding part 2-1 is a single-layer cloth, and a dead zone is formed by sewing along its boundary.

[0060] The closed area is isolated from the entire cavity and no gas is filled in. The shape and size of the closed area can be adjusted according to the requirements of the protection area.

[0061] The gas generator 11 is placed vertically through the bottom of the distal airbag and the studs are passed through the two mounting bolt holes 8 of the main fabric.

[0062] The air guide cloth 7 is overlapped with the main cloth according to the position of the mounting bolt hole 8, and the gas generator 11 is enclosed and wrapped. It is sewn along the boundary of the air guide cloth 7, and an upper exhaust hole 12 and a lower exhaust hole 12 are reserved. The gas generated by the gas generator 11 is controlled through these two exhaust holes 12 to fill the distal airbag cavity with the airflow according to the designed direction and air output.

[0063] Different air outlet directions and air outlet volumes have a significant impact on the deployment direction of the distal airbag, and also have a great impact on the stability of the distal airbag after inflation.

[0064] At the same time, two outer pull straps 5 are provided on the outside of the airbag body 1, one end of one of the outer pull straps 5 is connected to the mounting bolt hole 8 at the lower part of the gas generator 11, and the other end is sewn together with a sewing mark circle 9 of the outer pull strap on the main cloth.

[0065] One end of another outer drawstring 5 is connected to the mounting bolt hole 8 at the lower portion of the gas generator 11, and the other end is sewn together with the second sewing marking circle 10 of the outer drawstring on the closed area.

[0066] In order to ensure that the distal airbag can maintain a stable vertical upright state after inflation, the length and sewing position of the outer pull strap 5 are optimized. If the outer pull strap 5 is too short or too long, or even the sewing position is unreasonable, the distal airbag will be pulled off-center, destroying its stability after inflation, and thus failing to protect the occupants.

[0067] The above constitutes the technical solution of a remote airbag for protecting occupants in a side collision of a vehicle according to the utility model.

[0068] When the car is hit from the side, the distal airbag is rapidly deployed vertically, and under the coordinated action of the air guide cloth 7 and the inner and outer pull belts, a solid protective barrier is formed between the main and co-driver passengers. The upper inflation area effectively supports the Y-direction deviation of the passenger's head, and the length of the upper inner pull belt 3 is reasonably optimized to ensure the thickness of the upper inflation cavity to avoid being penetrated by the main and co-driver passengers' heads. At the same time, the size and shape of the main cloth piece of the airbag are reasonably optimized to block the swing of the passenger's head to the maximum extent, and prevent the passenger's head from sliding out of the protection area of ​​the airbag inflation cavity. This greatly reduces the damage to the passenger when a side collision occurs.

[0069] Obviously, the specific implementation of the present invention is not limited by the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
