Description

Technical Field

[0001] This utility model relates to the field of driver's seat airbag technology, specifically an adaptive driver's seat airbag structure. Background Technology

[0002] With the development of the automotive industry, airbags have become standard equipment in every car. A car's airbag, officially called an airbag system, is one of the core components of a vehicle's passive safety system. It works in conjunction with seat belts. In the event of a severe collision, it inflates instantly to form a flexible buffer barrier, preventing occupants from directly impacting hard parts of the vehicle body, thereby reducing the impact force and lowering the risk of injury or death. Traditional driver's airbag development considered the protective effect of the airbag on the driver in a fixed seating position during a collision. However, existing driver's seat airbag structures cannot protect drivers of different weights and driving habits, nor can they provide adaptive protection for drivers with different seating positions and weights during a collision, making them inconvenient to use. Utility Model Content

[0003] The purpose of this invention is to provide an adaptive driver's seat airbag structure to solve the problem mentioned in the background art that while it can protect drivers of different weights and driving habits, it cannot provide adaptive protection for drivers of different sitting positions and weights in the event of a vehicle collision, making it inconvenient to use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adaptive driver's seat airbag structure, including an airbag, wherein a third exhaust port is installed on one side of the surface of the airbag, and an external pull strap is installed on the surface of the third exhaust port; The outer pull strap is connected to an inner bag at its end, and the inner bag is connected to an MGG at its end. A burst line is provided between the outer pull strap and the inner bag, and an inflator is installed on one side of the surface of the air bag.

[0005] Preferably, the air bag is configured as a hollow cylindrical structure, and both sides of the air bag are configured as rounded corners.

[0006] By using the above technical solution, the air bag is inflated by inflating it, thus increasing its volume and causing it to expand.

[0007] Preferably, the third vent is installed on the same side of the air bag as the inflator.

[0008] Using the above technical solution, after the inflator is triggered, the air bag can be inflated through the inflator.

[0009] Preferably, the inflator is located at the center of one side of the air bag.

[0010] With the above technical solution, the inflator is located in the center of the air bag, making it easier to charge.

[0011] Preferably, the outer pull strap has a hollow structure inside, and the air bag and the inner bag are connected by the outer pull strap.

[0012] Using the above technical solution, the gas enters the interior of the outer pull strap through the third exhaust hole, and then enters the interior of the inner bag through the outer pull strap.

[0013] Preferably, the bursting line is located at the connection between the outer pull strap and the inner bag.

[0014] Using the above technical solution, when gas enters the outer pull belt, it can break open the burst line, which can then cause the inner bag to expand.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the adaptive driver's seat airbag structure: 1. It is equipped with an airbag, an outer pull strap, and an inner bag. When a vehicle collides, the inflator inflates the airbag, and the gas enters the hollow outer pull strap at the same time. The gas enters the interior of the inner bag through the outer pull strap, inflating the inner bag and causing it to expand. At this time, the expanded airbag and the expandable inner bag can effectively conform to the contours of the driver's body, improving the practicality of the device. 2. A burst line is installed. When the airbag is impacted, the pressure is higher, which will cause the burst line at the connection between the outer strap and the inner bag to burst more quickly. The inner bag will inflate and expand, forming a thicker buffer layer with the airbag to disperse greater impact force. When the driver is lighter, the burst line will burst later or partially, and the expansion of the inner bag can be controlled to avoid excessive cushioning and insufficient protection, thus adapting to the needs of drivers of different weights.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: an adaptive driver's seat airbag structure, including an airbag 10, a third exhaust port 20, an outer strap 201, an inner bag 202, an MGG 203, a burst line 204, and an inflator 30; This adaptive driver's seat airbag structure panel can better protect the driver. The specific implementation method is as follows: A third vent 20 is installed on one side of the surface of the air bag 10, and an outer pull strap 201 is installed on the surface of the third vent 20. The end of the outer pull strap 201 is connected to an inner bag 202, and the end of the inner bag 202 is connected to an MGG 203. A burst line 204 is provided between the outer pull strap 201 and the inner bag 202. An inflator 30 is installed on one side of the surface of the air bag 10. The air bag 10 is a hollow cylindrical structure, and both sides of the air bag 10 are rounded. The third vent 20 and the inflator 30 are installed on the same side of the air bag 10. The inflator 30 is located at the center of one side of the air bag 10. The outer pull strap 201 is hollow inside, and the air bag 10 and the inner bag 202 are connected by the outer pull strap 201. The burst line 204 is located at the connection between the outer pull strap 201 and the inner bag 202.

[0020] When the vehicle collision sensor triggers a signal, it transmits the signal to the airbag control system. At this time, the inflator 30 is opened, causing the inflator 30 to generate a large amount of gas instantly. The gas generated by the inflator 30 enters the interior of the airbag 10, pushing the airbag 10 to expand rapidly. During the expansion process, the rounded corner structure on both sides of the airbag 10 prevents the sharp edges from scratching the surrounding parts. At the same time, some gas flows through the airbag 10 to the interior of the third exhaust port 20 and enters the outer pull strap 201 connected to it. The gas flows in the hollow outer pull strap 201 and gradually fills the outer pull strap 201. MGG203 is a miniature gas generator. When activated, MGG203 is ignited, and the internal gas-generating composition burns rapidly, producing high-temperature, high-pressure gas. After a period of time triggered by the inflator 30, MGG203 is activated, and the high-pressure gas produced by MGG203 expands the bursting line 204. The extent to which the bursting line 204 breaks varies depending on the driver's body movement towards the device due to the impact and the applied pressure. If the driver is heavier, the impact pressure is higher, and the bursting line 204 breaks rapidly. The gas in the outer strap 201 quickly rushes into the inner bag 202, causing the inner bag 202 to expand rapidly. If the driver is lighter, the impact pressure is lower, the bursting line 204 breaks slowly or only partially, and the inflation speed of the inner bag 202 slows down, with a reduced degree of expansion.

[0021] Working principle: When using this adaptive driver's seat airbag structure, an outer pull strap 201, an inner pocket 202, an MGG 203, a burst line 204, and an inflator 30 are set up to better protect the driver and increase the overall practicality.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
