Technical Field

[0001] The utility model belongs to the technical field of automobiles, and specifically relates to a seat side airbag installation device and a vehicle. Background Art

[0002] Existing cars are equipped with multiple airbags, and the layout of the airbags has strict requirements, and there are many requirements for the airbags themselves and the surrounding environment. Not only are there requirements for the distance between the airbag and other components in static state, but also during the dynamic process of airbag deployment, no other components can block the deployment of the airbag. This requires sufficient space for the layout of the airbag.

[0003] Conventional side airbags are arranged in the seats. In existing 5-seater SUV cars, the rear seats are mostly split, and there are locking block structures on the sides of the seat backs to fix the backrests, resulting in insufficient space for the side airbags. This results in insufficient space for the rear seats to arrange the side airbags. How to use the limited space to arrange the lower side airbags and improve the safety of the entire vehicle is a difficulty in the arrangement of the rear side airbags.

[0004] For example, the patent document with the authorization announcement number CN206202224U discloses a car seat side airbag and a car including the side airbag, wherein the car seat side airbag includes a shell, an airbag and a protective cloth, wherein the protective cloth is wrapped around the outside of the airbag and matched with the shell. The technical solution disclosed in the patent document also cannot solve the technical problem described above. Utility Model Content

DETAILED DESCRIPTION

[0020] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of embodiments, with the aim of helping technicians in the field to have a more complete, accurate and in-depth understanding of the concept and technical solution of the utility model and facilitating its implementation.

[0021] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower" and similar expressions used in this article are for illustrative purposes only.

[0022] It should be noted that, in the following embodiments, the “first”, “second” and “third” mentioned do not represent an absolute distinction in structure and / or function, nor do they represent a sequence of execution, but are merely for the convenience of description.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field to which the present invention belongs. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] like Figures 1 to 6 As shown, the utility model provides a seat side airbag installation device, including a C-pillar assembly and a vehicle body bracket for supporting an airbag module 10. The airbag module 10 is installed on the C-pillar assembly, and the C-pillar assembly is located on the outer side of the rear seat of the car.

[0025] Specifically, if Figures 1 to 6 As shown, the C-pillar assembly includes a C-pillar guard plate 600, which is adjacent to the rear seat of the car, and the airbag module 10 is connected to the C-pillar guard plate 600 by snap connection, and the airbag module 10 is located inside the C-pillar guard plate 600. In this way, by changing the structure of the conventional seat side airbag, the soft bag airbag is changed to a hard shell airbag, and the arrangement position is adjusted from the inside of the seat to the inside of the C-pillar guard plate 600 outside the seat, and fixed to the car body through a bracket, the airbag is deployed from the inside of the C-pillar guard plate 600, which can protect the personal safety of the occupants.

[0026] like Figure 3 As shown, the airbag module 10 includes an airbag cover 100 , an airbag bag 200 , a gas generator 300 , a generator bracket 400 , and an airbag housing 500 .

[0027] The airbag bag 200 is folded in a specific manner to have the ability to be rapidly inflated.

[0028] The gas generator 300 is a cylindrical gas generating device.

[0029] The generator bracket 400 is a bracket for fixing the gas generator 300, and an air guide structure is added to the tail to ensure that the airflow flows in a specified direction, so that the airbag can be inflated more quickly.

[0030] The airbag shell 500 is a storage and support device for the entire airbag. After being folded, the airbag bag 200 is completely placed in the airbag shell 500 and fastened to the shell by bolts. The reverse impact force generated when the airbag is deployed is absorbed by the airbag shell 500, ensuring that the deployment posture of the airbag will not change and that it will inflate and deploy along the designed path.

[0031] The airbag cover 100 has two functions: first, to shield the airbag structure; second, the inner wall thereof plays a certain guiding role for the airbag during its deployment. A weakened structure is designed on the inner surface of the cover so that the airbag can quickly break through the cover when it expands.

[0032] like Figure 4 As shown, the inner side of the C-pillar guard plate 600 is designed with an airbag matching structure. On the one hand, it is necessary to support the airbag cover 100 to ensure that the airbag cover 100 will not be crushed during the use of the car. On the other hand, the bottom of the C-pillar guard plate 600 is provided with a snap-in structure for snapping with the airbag cover 100, which can improve the vibration and abnormal noise problems during the driving of the car. Figure 5 As shown, six buckles are disposed on the airbag cover 100 , namely a first buckle 110 , a second buckle 120 , a third buckle 130 , a fourth buckle 140 , a fifth buckle 150 and a sixth buckle 160 .

[0033] As a preferred embodiment, a plurality of vehicle body brackets are provided, and the vehicle body brackets are fixedly mounted on the vehicle body. An airbag bottom bracket is provided on the airbag module 10, and the airbag bottom bracket is connected to the vehicle body bracket by bolts.

[0034] like Figure 6 As shown, two body brackets are provided, namely a first body bracket 710 and a second body bracket 720. A first airbag bottom bracket 510 and a second airbag bottom bracket 520 are provided on the airbag housing 500. The first airbag bottom bracket 510 is connected to the first body bracket 710 by bolts, and the second airbag bottom bracket 520 is connected to the second body bracket 720 by bolts.

[0035] When a collision occurs, the airbag control module triggers an ignition signal to ignite the gas generator 300. The gas produced by the chemical reaction caused by combustion will pass through the diversion effect to inflate the airbag bag 200, and the airbag will expand rapidly. When the pressure of the airbag bag 200 reaches the limit of the airbag cover 100, the airbag cover 100 will be rushed open from the weakened position on the inside, and the airbag bag 200 will be deployed from the inside to absorb the impact from the side of the vehicle, thereby achieving the effect of protecting the occupants.

[0036] The utility model also provides a vehicle, including the seat side airbag installation device of the above structure. The specific structure of the seat side airbag installation device can be referred to Figures 1 to 6 Since the vehicle of the utility model includes the seat side airbag installation device in the above embodiment, it has all the advantages of the above seat side airbag installation device.

[0037] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
