TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile safety air bag, especially to a reinforced automobile safety air bag. BACKGROUND

[0002] Automobile safety air bag can quickly pop out when the car collides, providing a buffer protection for the passengers in the car, effectively reducing the collision damage.

[0003] The existing automobile safety air bag technology mostly uses simple safety air bags for protection, but this way cannot accurately and effectively provide all-round and multi-level protection for the head, chest and other key parts of the driver and passenger. For example, a Chinese patent "reinforced automobile safety air bag" (application number CN201520827698.4) uses sponge pieces on the surface of the air bag bag, which contacts the human body when the air bag bag is unfolded, providing better buffering effect. However, when a collision occurs, the head is more likely to be injured, and the head is the first to be injured. A slight time difference will cause the head to be injured. SUMMARY

[0004] The utility model aims at at least solving one of the technical problems existing in the prior art, providing a reinforced automobile safety air bag. The device can provide multi-level and multi-angle buffer protection for the head and chest of the driver and passenger when the car collides. First, the gas rushes into the head protection cavity, causing the first air bag bag and the second air bag bag to rapidly expand, and then the inner air bag bag, the first soft pad and the first buffer pad inside are also inflated, providing preliminary buffer support for the head of the driver and passenger, effectively reducing the impact force on the head in the collision moment, greatly ensuring the safety of the head. Then the gas enters the chest protection cavity, allowing the second buffer pad inside to relax, thereby providing good protection for the chest of the driver and passenger, effectively preventing the chest from being injured during the collision process.

Through the above device, the position of the head protection cavity allows the airbag bag at the head position to be generated first, thereby providing head protection.

[0008] According to the reinforced automobile airbag of the present invention, the head protection chamber is in contact with the gas generator, and the chest protection chamber and the head protection chamber are connected through the first and second air holes. With this device, gas from the head protection chamber is transported through the first and second air holes to the chest protection chamber, thereby protecting the chest.

[0009] According to the reinforced automobile airbag of the present invention, the partition membrane is provided with a laminate, and the first and second air holes penetrate the partition membrane. Through the above device, the laminate is made to fold the partition membrane, and the chambers are tightly fitted to each other.

[0010] According to the reinforced automobile airbag of the present invention, the first cushion is fixedly connected to the top of the head protection cavity, and the second cushion is fixedly connected to the top of the chest protection cavity. Through the above device, the first and second cushions enhance the cushioning effect of the airbag, thereby more effectively protecting the occupants of the vehicle.

[0011] The utility model relates to a reinforced automobile safety air bag, first buffer pad is provided with through -hole, through -hole communicates with second air bag bag.

[0012] The utility model relates to a reinforced automobile safety air bag, first buffer pad and second buffer pad are polyurethane pad, first buffer pad and second buffer pad are compression shape.

[0013] Advantageous effects

[0014] Compared with the prior art, the reinforced automobile safety air bag can provide multilayer and multi-angle buffer protection for the head and chest of the driver and passenger when the automobile collides, the gas first rushes into the head protection cavity, makes the first air bag bag and the second air bag bag rapidly expand, and then drives the inner air bag bag, the first soft pad and the first buffer pad to expand, provides preliminary buffer support for the head of the driver and passenger, effectively reduces the impact force of the head in the collision moment, greatly guarantees the safety of the head, and then the gas enters the chest protection cavity, relaxes the second buffer pad in the inside, thereby good protection is provided for the chest of the driver and passenger, and injury of the chest in the collision process is effectively prevented.
