Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1 to 4, an airbag device is provided on a center tunnel 2 in a vehicle 1, the center tunnel 2 is located between a driver seat 3 and a passenger seat 4, that is, a receiving cavity is provided on the center tunnel 2, the airbag device is received in the receiving cavity, and a reversible cover plate is provided on the receiving cavity, the airbag device includes a gas generator and an airbag, the gas generator is connected to an ECU on-vehicle body, the ECU is connected to a collision sensor, the collision sensor detects a collision on the vehicle and transmits collision information to the ECU, the ECU makes a judgment, when the airbag needs to be detonated, the ECU sends a signal to the generator, the generator inflates and detonates the airbag, the airbag rushes out of the cover plate and fully develops between the driver and the passenger, and protects the driver and the passenger to prevent a secondary collision between the driver and the passenger, the principle of use of the airbag device and the prior art are not described in detail herein.
The air bag includes bag body 5, and bag body 5 is inside to be gas chamber 6, and bag body 5 is including the first portion 7, second portion 8 and the third portion 9 that connect gradually, and gas chamber 6 runs through first portion 7, second portion 8 and third portion 9 in proper order, and bag body 5 fully expandes the back, and first portion 7, second portion 8 and third portion 9 are the U type, and first portion 7 sets up with third portion 9 relatively, and first portion 7 deviates from the one side each other with third portion 9 and is protective surface 10, and 8 lower extremes of second portion are equipped with the inlet port, the inlet port with gas chamber 6 is linked together.
The one side that first portion 7 and third portion 9 deviate from each other is protection face 10, and driver and passenger when the car accident, driver and passenger hit on protection face 10 promptly, protect driver and passenger through the protection of air bag to be the U type after the air bag expandes, increased the thickness of the air bag between driver and the passenger, can prevent effectively that driver and passenger from taking place secondary collision, the guard effect is better.
In this embodiment, the bag body 5 is a two-piece type, and includes an upper piece 11 and a lower piece 12 which are arranged up and down, the upper piece 11 and the lower piece 12 are sewn together, the upper piece 11 and the lower piece 12 enclose the gas chamber 6, in order to ensure the shape of the bag body 5 after being unfolded, a plurality of drawstrings are arranged between the upper piece 11 and the lower piece 12, and after the bag body 5 is fully unfolded, the drawstrings are vertically connected with the upper piece 11 and the lower piece 12.
At least one connecting part 13 is arranged between the first part 7 and the third part 9, and a connecting channel 14 for communicating the first part 7 and the third part 9 is arranged in the connecting part 13. By means of the connecting channels 14, the bag body 5 can be inflated quickly and uniformly.
The first part 7 and the third part 9 are provided with a suture line 15, a suture part 16 is formed between the suture line 15 and the lower end of the first part and between the suture line 15 and the lower end of the third part, and the suture part 16 is sealed and isolated from the gas chamber 6. Because the gas generator can generate less gas and the secondary collision between the driver and the passenger is mainly concentrated on the head, the first part 7 and the third part 9 are sewed, so that the gas can be effectively utilized during the secondary collision, and the effective protection effect of the airbag is ensured.
Specifically, the vertical height D of the sewing part 16 is 30% -120% of the H value, the H value is the height from the leg part to the shoulder part of the dummy positioned on the seat in the automobile collision test, and the vertical height D of the sewing part is preferably 50% -100% of the H value.
The second portion 8 is located between the stitched part 16 of the first portion 7 and the stitched part 16 of the third portion 9, and the gas entering the gas inlet hole is diffused towards the first portion 7 and the third portion 9 through the second portion 8.
In this case, a heat insulating sheet is sewn into the bag body 5, and the heat insulating sheet is close to the air inlet.
In order to support the airbag, the airbag can be better protected, after the airbag is completely unfolded, one end of the first part 7, which deviates from the second part 8, of the third part 9 is in contact with an instrument panel 17 in the automobile, and the upper end of the first part 7, which is in contact with the upper end of the third part 9, of the third part is in contact with an inner top 18 of the automobile. The safety airbag is supported by the instrument panel 17 and the top 18 in the automobile, so that the safety airbag is not easy to deviate, and the anti-collision effect is better achieved.
When the side of the automobile collides, the bag body 5 pops out to prevent the secondary collision between the driver and the passenger, and when the automobile collides positively, the bag body 5 pops out to prevent the lateral deviation between the driver and the passenger, so that the effectiveness of the safety airbag of the main driver seat and the auxiliary driver seat is ensured, and the protection effect is good.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
