In some embodiments of the present utility model, as shown in fig. 1 to 3, the side airbag includes a first air chamber 1, a second air chamber 2, and a third air chamber 3, the second air chamber 2 is disposed at one side of the first air chamber 1, the second air chamber 2 is extended toward the direction of an occupant on a seat 10 when deployed, and the third air chamber 3 is disposed at the other side of the first air chamber 1 to be in contact with an adjacent seat 20.

Specifically, the second air chamber 2 and the third air chamber 3 are disposed on the left and right sides of the first air chamber 1, respectively. When inflated, the second air chamber 2 expands toward the occupant of the seat 10, and the third air chamber 3 expands toward the adjacent seat 20 and brings the third air chamber 3 into contact with the adjacent seat 20.

Since the third air chamber 3 is in contact with the adjacent seat 20, the side airbag can be supported by the adjacent seat 20. When a side collision occurs, the passengers sitting on the seats 10 fall to the first air chamber 1 and the second air chamber 2, and are protected by the first air chamber 1 and the second air chamber 2, so that the passengers on the two seats are prevented from striking each other, and secondary injury is caused. At this time, the third air chamber 3 is in contact with the adjacent seat 20, preventing the side airbag from collapsing when in contact with the human body. The third air chamber 3 makes the positions of the first air chamber 1 and the second air chamber 2 relatively stable, and effectively protects the occupant.

Preferably, the first air chamber 1 is connected to a seat frame of a seat 10. Before inflation, the side airbag is folded into the seat frame of the seat 10. The first air chamber 1 is connected with the seat frame to avoid falling off after the side safety air bag is unfolded.

Alternatively, the side airbag may be mounted on a ceiling in the vehicle, and the side airbag is deployed from above to below when deployed.

Further, as shown in fig. 3, a gas generator (not shown) is directly connected to the first gas chamber 1. The first air chamber 1 is a main air chamber, and when the air is inflated, air firstly enters the first air chamber 1, and then enters the second air chamber 2 and the third air chamber 3 from the first air chamber 1. The second air chamber 2 is unfolded from the right side along fig. 3 and the third air chamber 3 is unfolded from the left side along fig. 3.

Alternatively, the gas generator may be directly connected to the third gas chamber 3, the third gas chamber 3 is unfolded and then brought into contact with the adjacent seat 20, and then the gas flows from the third gas chamber 3 into the first gas chamber 1 and the second gas chamber 2 in sequence.

Alternatively, as shown in fig. 4, the second air chamber 2 and the third air chamber 3 are connected to the upper and lower sides of the first air chamber 1, the first air chamber 1 is connected to the upper seat frame of the seat 10, the air is inflated from the first air chamber 1 and then enters the third air chamber 3 and the second air chamber 2, the third air chamber 3 is unfolded to be in contact with the side face of the adjacent seat 20, and the second air chamber 2 is unfolded toward the occupant on the adjacent seat 20.

Further, as shown in fig. 3, the first air chamber 1 is communicated with the second air chamber 2 through a first air hole 4, and the first air chamber 1 is communicated with the third air chamber 3 through a second air hole 5.

Specifically, the number of the first air holes 4 may be one or more, and the number of the second air holes 5 may be one or more.

Further, as shown in fig. 2, the rear side surface of the second air chamber 2 is formed with a concave portion 21 recessed forward, the concave portion 21 being for contact with the head of the occupant.

Specifically, the second air chamber 2 has an elongated structure extending in the lateral direction after being expanded, and a concave portion 21 is formed on the rear side surface of the second air chamber 2, and the concave portion 21 can be brought into contact with the front side (face) of the head of the occupant.

As shown in fig. 3, the concave portion 21 of the second air chamber 2 can just protect the head of the human body when a collision occurs. While the first air chamber 1 is capable of protecting the sides of the human body from collision with an occupant of an adjacent seat 20. The first air chamber 1 and the second air chamber 2 wrap the human body together, so that a better protection effect can be achieved.

Optionally, the second air chamber 2 can be designed to have a larger coverage area, and can be deployed in front of the head and chest of the human body, so as to increase the protection of the head and chest of the human body.

Further, the second air cells 2 are expanded in the lateral direction. As shown in fig. 3, the second air chamber 2 in this embodiment is deployed from the first air chamber 1 rightward toward the occupant of the seat 10.

Alternatively, the second air cells 2 may also be deployed in the lateral direction toward the occupant of the adjacent seat 20 on the left side for protecting the occupant on the adjacent seat 20.

Further, as shown in fig. 3, the second air chamber 2 is connected above one side of the first air chamber 1 for protecting the head of the human body, and the third air chamber 3 is connected below the other side of the first air chamber 1, in contact with the back side of the seat.

Alternatively, the third air chamber 3 may be provided in the middle or above the first air chamber 1 in contact with other parts of the seat. The second air chamber 2 may also be disposed in the middle of the first air chamber 1 for protecting the chest and abdomen of a human body.

Further, as shown in fig. 1-2, the third air chamber 3 is spherical after being expanded.

Alternatively, the third air chamber 3 may be designed in other shapes.

Further, the first air chamber 1 is elliptical.

Alternatively, the first air chamber 1 can also be designed in other shapes.

In another embodiment of the present utility model, as shown in fig. 5, a center console 30 is provided between the seat 10 and the adjacent seat 20. When the third air chamber 3 is deployed, the third air chamber 3 is deployed toward the space between the occupant of the adjacent seat 20 and the center console 30, and on the one hand, the third air chamber 3 enters between the center console 30 and the adjacent seat 20 and can be supported; on the other hand, the third air chamber 3 is in contact with the occupant in the adjacent seat 20, and can function to protect the occupant from rib and pelvis collision injuries.

Further, as shown in fig. 5, a pull strap 6 is further provided between the third air chamber 3 and the first air chamber 1, and the pull strap 6 functions to adjust the deployment posture of the third air chamber 3.

The side airbag of the utility model is suitable for vehicle models with a central console and vehicle models without the central console. The body of the passenger is protected through the second air chamber, and the third air chamber is contacted with the seat or the adjacent passenger to play a role of supporting the side safety air bag, so that the passenger is effectively protected in the side collision process.

What has been described above is merely illustrative of the principles and preferred embodiments of the present utility model. It should be noted that several other variants are possible to those skilled in the art on the basis of the principle of the utility model and should also be considered as the scope of protection of the present utility model.
