[0028] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0029] Reference below Figure 1-Figure 4 A backrest structure 10 for a seat 11 according to an embodiment of the present invention is described, comprising a back plate 100 , foam 200 and an airbag assembly 300 .

[0030] It should be noted that the backrest structure 10 is suitable for being built in the seat 11. Now when the user is in the driving position in the vehicle, in order to make the user sit more comfortably in the vehicle, the user's sitting posture is in a horizontal position, similar to a zero sitting posture. In this way, when a collision or other situations occur, the user's sitting posture is poor, which makes the user more likely to have safety hazards, thereby affecting the user's safety in the vehicle.

[0031] Moreover, during the use of the backrest structure 10, a sensor is installed in the vehicle, and the sensor is suitable for detecting the user's sitting posture on the seat. When the vehicle detects an imminent collision risk and the user's sitting posture is in an unconventional sitting posture, a control signal is sent through the controller to drive the airbag assembly 300 in the backrest structure for use, so that the airbag assembly 300 is suitable for driving the foam to move so that the foam drives the user's sitting posture to be corrected.

[0032] Specifically, the back panel 100 is arranged on the seat 11; the foam 200 is arranged on one side of the back panel 100; the airbag assembly 300 is arranged between the foam 200 and the back panel 100, and the airbag assembly 300 includes: an airbag body 320, the vertical cross-section of the airbag body 320 is triangular, and the expansion side of the airbag body 320 is in contact with the foam 200.

[0033] Therefore, a backrest structure 10 is provided on the seat body, and the backrest structure 10 includes: a back plate 100, a foam 200 and an airbag assembly 300. The back plate 100 is suitable for providing support so that the airbag assembly 300 can be built in the seat 11, so that when a danger is detected, the airbag assembly 300 can be expanded, and the expansion direction of the airbag assembly 300 is toward the foam 200, so that the foam 200 can drive the user's sitting posture to be corrected at a higher speed, so that the safety of the user in the vehicle is improved.

[0034] Moreover, by setting the vertical cross-section of the airbag body 320 into a triangle, the expanded side of the airbag body 320 is in contact with the foam 200, so that when danger is detected, it is suitable to open the airbag body 320. One side of the airbag body 320 is in contact with the back panel 100, so that the expanded side of the airbag body 320 is in contact with the foam, so that the airbag body 320 can drive the foam 200 to move during the expansion process. Since one end of the foam 200 is connected to the seat 11, the foam 200 is suitable for driving the user's body to adjust the sitting posture while being driven by the airbag body 320, thereby improving the safety of the user in the car.

[0035] According to the backrest structure 10 of the embodiment of the utility model, by providing an airbag assembly 300 between the back plate 100 and the foam 200, when it is detected or identified that the user is at risk when in the zero sitting position, the airbag assembly 300 can be driven to expand toward the foam 200, so that the airbag assembly 300 can support the user to correct the sitting position more quickly, so that the user's body can return to a normal sitting position to reduce the risk. At the same time, because the structure of the airbag bladder 320 is set to be triangular, the expanded side of the airbag bladder 320 is in conflict with the foam 200, so that the airbag bladder 320 drives the foam 200 to move during the expansion process to achieve rapid correction of the user's sitting position.

[0036] In some embodiments, the airbag assembly 300 further includes an airbag bracket 310, the airbag bracket 310 is connected to the back plate 100, and the airbag body 320 is received in the airbag bracket 310. It is understandable that the airbag bracket 310 is suitable for providing an installation position so that the airbag body 320 can be assembled into the airbag bracket 310, so that the setting process of the airbag assembly 300 on the back plate 100 is simpler, and the arrangement of the airbag assembly 300 in the seat 11 is more reliable, so that the airbag assembly 300 can be used according to user needs, so that the safety of the user in the car is improved.

[0037] In some embodiments, the airbag assembly 300 further includes an auxiliary airbag 330, which is disposed in the airbag bracket 310 and disposed on the upper part of the airbag body 320. It is understandable that the auxiliary airbag 330 is disposed on the upper part of the airbag body 320 so that the auxiliary airbag 330 can protect the head of the user, thereby avoiding whiplash injuries that may be caused by the rapid forward rotation of the occupant's torso, and the safety of the user in the car is improved.

[0038] In some embodiments, the airbag body 320 is made of a flexible material, and a coating is provided on the surface of the airbag body 320. It is understandable that setting the airbag body 320 as a flexible material can allow the airbag body 320 to have a higher performance during the expansion process so that the airbag assembly 300 can support the user to correct the sitting posture. At the same time, providing a coating on the surface of the airbag body 320 can improve the airtightness of the airbag body 320, so that the performance of the airbag body 320 during use is improved.

[0039] In some embodiments, the airbag bracket 310 can be a metal bracket, which not only facilitates the connection between the airbag bracket 310 and the back plate 100, but also has a higher stability. At the same time, it can also provide a more reliable bearing capacity so that the airbag body 320 can be arranged in the airbag bracket 310, so that the performance of the airbag assembly 300 is higher.

[0040] In some embodiments, the expanded volume of the airbag 320 is A, and the volume A satisfies the relationship: 35L≤A≤65L. It is understandable that the expandable volume of the airbag 320 is not too large or too small. If the volume of the airbag 320 is too large, the airbag 320 will overcorrect the sitting posture after expansion, thereby driving the user to collide with the steering wheel, causing a safety hazard. If the volume of the airbag 320 is too small, the airbag 320 will not be able to correct the sitting posture well after expansion, so that the user has a certain risk. Therefore, the expanded volume of the airbag 320 can be set to 35L to 65L, so that the airbag 320 can better correct the user's sitting posture within a safe range after expansion. In some specific embodiments, the expanded volume of the airbag 320 is between 40L and 60L, so that the performance of the airbag 320 can be improved.

[0041] In some embodiments, the side of the airbag body 320 is provided with a corresponding air leakage hole 321, and the air leakage hole 321 is a circular hole. It can be understood that since the air leakage hole 321 is provided on the side of the airbag body 320, the airbag body 320 can be deflated through the air leakage hole 321 after being inflated, so that the use of the airbag body 320 is safer and more reliable. In some specific embodiments, in order to make the exhaust of the air leakage hole 321 more uniform, the air leakage hole 321 can be set as a circular hole.

[0042] In some embodiments, the upper change trend of the airbag bladder 320 is smaller than the lower change trend of the airbag bladder 320. It can be understood that by making the upper change trend of the airbag bladder 320 smaller than the lower change trend of the airbag bladder 320, the expansion point of the airbag bladder 320 is closer to the lower side of the user's upper body, so that the user's sitting posture correction efficiency is higher.

[0043] In some embodiments, a drawstring 322 is provided in the airbag body 320, and the drawstring 322 is multiple and arranged at intervals in the vertical direction. It can be understood that by providing the drawstring 322 in the airbag body 320, the structural performance of the airbag body 320 is improved, so that the airbag body 320 can act on the user's body more evenly and reliably after expansion, avoiding excessive force on the user's spine.

[0044] In some embodiments, a weakened portion 210 is provided on the foam 200, and the weakened portion 210 is a weakened line or a weakened groove. In this way, the weakened portion 210 is suitable for guiding the airbag assembly 300 to normally deploy to drive the user to correct the sitting posture, and at the same time, the airbag can be prevented from directly contacting the user during the deployment process to improve the safety of use.

[0045] The vehicle according to the embodiment of the utility model includes the backrest structure 10 for the seat 11 as shown above. In this way, since the backrest structure 10 for the seat 11 as shown above is provided inside the vehicle, by providing the airbag assembly 300 between the back plate 100 and the foam 200, when it is detected or identified that the user is at risk when in the zero sitting position, the airbag assembly 300 can be driven to expand toward the foam 200, so that the airbag assembly 300 can support the user to correct the sitting position more quickly, so that the user's body can return to the normal sitting position to reduce the risk.
