Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, specifically to an automotive seat cover that ensures unobstructed deployment of side airbags. Background Technology

[0002] A car seat cover that ensures unimpeded deployment of side airbags refers to a specially designed car seat cover manufactured using specific materials and processes. Its key feature is that it does not prevent the side airbags installed on the outer side of the car seat back (or shoulder area) from deploying normally according to the original design path, timing, and force in the event of a side collision, thereby providing the occupants with the necessary side collision protection.

[0003] In the event of a frontal collision, occupants will move forward due to inertia. In this situation, the steering wheel airbag should deploy first, followed by the side airbags. However, existing car seat covers typically lack an independent airbag system, or even if they do, their triggering mechanism may be incompatible with the original airbag system, failing to achieve optimal deployment timing control for side collisions. Therefore, we need to propose a car seat cover that ensures unimpeded deployment of side airbags. Utility Model Content

[0004] The purpose of this invention is to provide a car seat cover that ensures unobstructed deployment of side airbags, with the advantage of segmented deployment of side airbags and steering wheel airbags, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a car seat cover that ensures unobstructed deployment of side airbags, comprising a seat body, a fixing mechanism for fixing the car chassis is provided below the seat body, a connecting mechanism for connecting the fixing mechanism is provided at the bottom of the seat body, an airbag mechanism for ensuring lateral deployment is provided inside the seat body, and a detection mechanism for detecting whether the side has been impacted is provided inside the door on one side of the seat body.

[0006] Preferably, the fixing mechanism includes a mounting plate disposed below the seat body, the mounting plate having a mounting hole on its surface that extends through the mounting plate, and a screw being disposed inside the mounting hole and extending below the mounting hole.

[0007] Preferably, the connecting mechanism includes a first dovetail block, which is disposed at the bottom of the seat body, and the surface of the mounting plate is provided with a first dovetail groove, wherein the first dovetail block is adapted to the first dovetail groove.

[0008] Preferably, the airbag mechanism includes a placement chamber disposed inside the seat body, an airbag body disposed inside the placement chamber, a compressed air box disposed inside the placement chamber, a solenoid valve disposed on one side of the compressed air box, the side of the solenoid valve away from the compressed air box being connected to the airbag body, and an airbag rupture port being provided on one side of the seat body.

[0009] Preferably, the detection mechanism includes a base plate installed inside the vehicle door, a pressure sensor is provided on one side of the base plate, a protective plate is provided on one side of the base plate, and a force transmission mechanism for transmitting impact force is provided on the inner wall of the protective plate.

[0010] Preferably, the force transmission mechanism includes a second dovetail block, which is disposed on the inner wall of the guard plate. A spring is disposed above the bottom plate, and a contact plate is disposed at the end of the spring away from the bottom plate. A second dovetail groove is provided on one side of the contact plate, and the second dovetail groove is adapted to the second dovetail block.

[0011] Preferably, a controller is provided at the bottom of the seat body, and the controller is electrically connected to the solenoid valve and the pressure sensor.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model features an airbag mechanism, including a compressed air chamber and a solenoid valve, independently installed inside the seat body and electrically connected to a detection mechanism and controller inside the door. This allows for precise control of the side airbag deployment timing. This effectively solves the problem in existing technologies where simultaneous deployment of the side airbag and steering wheel airbag may cause secondary injury to the occupant. By delaying the deployment or triggering a condition, occupant safety is ensured.

[0014] 2. This utility model features a specially designed placement compartment inside the seat body and an airbag deployment port on the side, providing a pre-defined and unobstructed path for the airbag's deployment. This integrated design avoids the risk of obstructed side airbag deployment caused by adding ordinary seat covers, ensuring that the airbag can deploy quickly and smoothly in the event of a collision, providing immediate protection.

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a car seat cover that ensures unimpeded deployment of side airbags, comprising a seat body 1, with a fixing mechanism for securing the car chassis located below the seat body 1; the fixing mechanism includes a mounting plate 2, which is positioned below the seat body 1, and has mounting holes 3 extending through its surface; a screw 4 is disposed inside the mounting holes 3 and extends below the mounting holes 3. This provides a mechanical rigid fixing solution. Through the mounting plate 2 and the screw 4, the base of the entire seat cover is securely installed on the car chassis, ensuring the stability of the system during vehicle driving and collisions, providing a foundation for reliable airbag deployment. During installation, the screw 4 is passed through the mounting holes 3 on the mounting plate 2 and tightened onto the corresponding threaded holes on the car chassis, completing the base fixing.

[0024] The bottom of the seat body 1 is provided with a connecting mechanism for connecting the fixing mechanism. The connecting mechanism includes a first dovetail block 5, which is located at the bottom of the seat body 1. A first dovetail groove 6 is formed on the surface of the mounting plate 2, and the first dovetail block 5 is adapted to the first dovetail groove 6. A sliding insertion method is adopted, in which the first dovetail groove 6 and the first dovetail block 5 cooperate. This design enables quick docking and separation between the seat cover body and the fixing base, while ensuring the stability after connection, and facilitating the removal, replacement or maintenance of the seat cover. During installation, the first dovetail block 5 at the bottom of the seat body is slid into the first dovetail groove 6 on the mounting plate until it is locked. During disassembly, it is slid out in the opposite direction.

[0025] The seat body 1 has an internal airbag mechanism for lateral protection. The airbag mechanism includes a placement chamber 7, which is located inside the seat body 1. Inside the placement chamber 7 is the airbag body 8, and inside the placement chamber 7 is a compressed air tank 9. A solenoid valve 10 is located on one side of the compressed air tank 9, and the side of the solenoid valve 10 away from the compressed air tank 9 is connected to the airbag body 8. An airbag rupture port 11 is located on one side of the seat body 1. This is an independent inflatable airbag system. The compressed air tank 9 serves as the air source, and the solenoid valve 10 acts as a switch to control the airflow. In the non-operating state, the solenoid valve 10 is closed, and the compressed gas is sealed inside the compressed air tank 9. When a trigger command is received, the solenoid valve 10 opens instantaneously, and high-pressure gas rushes into the airbag body 8, causing it to rapidly inflate and burst out through the preset rupture port 11. The controller sends an electrical signal, solenoid valve 10 is energized and opened, and high-pressure gas in compressed air box 9 rushes into airbag body 8 through solenoid valve 10. Airbag body 8 expands instantly and bursts open airbag rupture port 11, forming a buffer protective pad between the occupant and the car door.

[0026] A detection mechanism for detecting side impact is installed inside the door on one side of the seat body 1. The detection mechanism includes a base plate 12, which is installed inside the door. A pressure sensor 13 is installed on one side of the base plate 12, and a guard plate 14 is installed on one side of the base plate 12. The inner wall of the guard plate 14 is provided with a force transmission mechanism for transmitting impact force. The force transmission mechanism includes a second dovetail block 15, which is located on the inner wall of the guard plate 14. A spring 16 is installed above the base plate 12. A contact plate 17 is installed at the end of the spring 16 away from the base plate 12. A second dovetail groove 18 is formed on one side of the contact plate 17, and the second dovetail groove 18 is adapted to the second dovetail block 15.

[0027] A "buffer-sensing" mechanism was simulated. When the car door is impacted, the contact plate 17 first contacts the impacting object, and the impact force is smoothly transmitted to the pressure sensor 13 on the bottom plate through the internal force transmission mechanism spring 16. The spring 16 acts as a buffer and maintains the preload, ensuring that only impact forces reaching a certain threshold can be effectively sensed. The cooperation between the second dovetail block 15 and the second dovetail groove 18 ensures the stability and accurate alignment of the connections between the components of the force transmission mechanism. In the event of a side collision, the contact plate 17 is compressed, pushing the contact plate 17 to compress the spring 16. The contact plate 17 then transmits the pressure to the pressure sensor 13 at the bottom. When the pressure sensor 13 reaches the trigger threshold, it generates an electrical signal and sends it to the controller.

[0028] A controller is installed at the bottom of the seat body 1, and the controller is electrically connected to the solenoid valve 10 and the pressure sensor 13. The controller receives data from the pressure sensor 13 in real time to determine whether a side collision has occurred. If a collision is confirmed, the controller immediately outputs a starting current to the solenoid valve 10, and the airbag body 8 deploys.

[0029] 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.
