Description

Technical Field

[0001] This utility model mainly relates to the field of automotive parts technology, specifically to an ultra-thin side airbag structure for the right front seat. Background Technology

[0002] The car's airbag system is a key component of its passive safety system, with side airbags cleverly installed in the side wing of the seat. When a vehicle is involved in a side collision, the side airbags deploy rapidly, providing immediate cushioning protection for the occupants and effectively reducing the impact force on their bodies, thereby significantly improving their chances of survival and safety in an accident.

[0003] While traditional single-chamber airbags can inflate rapidly in side-impact collisions, their cushioning effect is limited, making it difficult to effectively protect critical areas such as the chest and abdomen of passengers. Furthermore, single-chamber airbags are prone to puncture during a collision, leading to loss of cushioning, and installation is also inconvenient. Utility Model Content

[0004] This utility model mainly provides an ultra-thin side airbag structure for the right front seat to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] The ultra-thin side airbag structure of the right front seat includes a seat, a seat part is fixedly connected to the bottom of the seat, and a placement groove is provided on one side of the seat. The upper and lower ends of the inner wall of the placement groove are provided with mounting mechanisms, and an airbag cover is connected between the two mounting mechanisms.

[0007] Preferably, the installation mechanism includes a positioning block, an installation block, and bolts. Positioning blocks are provided at both the upper and lower ends of the inner wall of the placement groove, and the installation block is movably connected to the outer side of the positioning block through a mounting hole. Bolts are provided on the surface of the installation block, and the bolts fix the installation block inside the placement groove. At the same time, one end of each of the two installation blocks is connected to both ends of the airbag cover.

[0008] Preferably, the length of the mounting block at the top of the airbag cover is greater than the length of the mounting block at the bottom of the airbag cover.

[0009] Preferably, a cover is connected to one side of the airbag cover, and a sensor is connected to the bottom wall of the airbag cover. The airbag cover has an inner cavity airbag inside, and an outer cavity airbag is provided on one side of the inner cavity airbag. An exhaust hole is opened between the outer cavity airbag and the inner cavity airbag, and an ignition device is connected to the bottom of the outer cavity airbag.

[0010] Preferably, the height of the bottom of the placement slot is higher than the height of the seat.

[0011] Preferably, the inflated inner cavity airbag is V-shaped, and the width in the middle of the inner cavity airbag is smaller than the width at both ends of the inner cavity airbag.

[0012] Preferably, both the inner and outer airbags are made of a high-strength, low-thickness composite material, which is polyamide (PA).

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] With its dual-chamber airbag design, the outer airbag inflates first in the event of a side impact, forming a high-rigidity protection that effectively withstands external impacts and reduces the direct impact of collision energy on passengers. Subsequently, the inner airbag inflates through the vent of the outer airbag, providing a softer cushioning and preventing secondary injuries to the passenger's chest. This staged inflation method not only optimizes the cushioning effect but also significantly reduces the risk of injury to passengers in side collisions, especially in protecting critical areas such as the chest and abdomen, providing passengers with more comprehensive safety protection.

[0015] By using positioning blocks and mounting blocks, the airbag cover can be quickly positioned and then fixed to the inner wall of the placement slot with bolts. This design not only simplifies the installation process and improves installation efficiency, but also ensures the stability of the airbag cover during vehicle operation. The modular installation method facilitates subsequent maintenance and replacement, reducing maintenance costs and time.

[0023] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example

[0024] Please refer to the appendix carefully. Figure 1-5 The ultra-thin side airbag structure of the right front seat includes a seat 1, a seat part 2 fixedly connected to the bottom of the seat 1, and a placement groove 3 opened on one side of the seat 1. The bottom of the placement groove 3 is higher than the height of the seat part 2, which helps the airbag to better cover the passenger's chest and abdomen when deployed. The upper and lower ends of the inner wall of the placement groove 3 are provided with mounting mechanisms 4. The mounting mechanism 4 includes a positioning block 401, a mounting block 402, and a bolt 403. The upper and lower ends of the inner wall of the placement groove 3 are provided with positioning blocks 401. The outer side of the positioning blocks 401 is movably connected to the mounting blocks 402 through mounting holes. The surface of the mounting blocks 402 is provided with bolts 403, which firmly fix the mounting blocks 402 inside the placement groove 3. Two mounting blocks 402 are connected at one end to both ends of the airbag cover 5 to ensure stable installation of the airbag cover 5 inside the seat 1. The length of the mounting block 402 at the top of the airbag cover 5 is greater than the length of the mounting block 402 at the bottom of the airbag cover 5 to prevent it from being installed backwards. A cover 6 is connected to one side of the airbag cover 5 to protect the internal components of the airbag and optimize the gas flow when the airbag deploys. A sensor 7 is connected to the inner bottom wall of the airbag cover 5. This sensor 7 can monitor the acceleration, pressure or other relevant parameters during a side collision of the vehicle in real time and transmit the signal to the vehicle's airbag control unit. The airbag cover 5 contains an inner cavity airbag 8 and an outer cavity airbag 9, both of which are made of high-strength, low-thickness polyamide 66 (PA66) composite material. This material can not only ensure the stability of the airbag... The airbag expands rapidly during inflation, providing sufficient cushioning while effectively reducing the overall thickness of the airbag to meet the requirements of ultra-thin design. The inner airbag 8, after inflation, is V-shaped, with the width of the middle section being smaller than the width of the two ends. This allows the inner airbag 8 to better conform to the passenger's body contours when deployed, providing a more uniform cushioning effect while avoiding excessive compression of the passenger's chest and abdomen. The outer airbag 9 is located on one side of the inner airbag 8, with an exhaust port 10 between them for rapid gas conduction and distribution during airbag inflation. The bottom of the outer airbag 9 is connected to an ignition device 11, which receives a signal from the ECU and ignites rapidly when a side collision occurs, generating a large amount of gas to inflate the airbag, thereby achieving rapid airbag deployment and providing timely protection for the passenger.

[0025] The specific operation method of this utility model is as follows:

[0026] When the vehicle is involved in a collision, sensor 7 quickly calculates the impact force. If it exceeds a predetermined threshold, ignition device 11 rapidly deploys the outer airbag 9 and the inner airbag 8. The outer airbag 9 is inflated to form a high-rigidity protection to withstand external impacts, while the inner airbag 8 is inflated through the exhaust port 10 of the outer airbag 9 to provide a softer cushioning. This protects the passenger while preventing secondary injuries to the passenger's chest from the airbag.

[0027] When installing the airbag cover 5, align the mounting blocks 402 at both ends of the airbag cover 5 with the positioning blocks 401 and push them inward to complete the positioning. Then, use bolts 403 to fix the mounting blocks 402 to the inner wall of the placement groove 3 to complete the installation.

[0028] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
