Description

Technical Field

[0001] This utility model relates to the field of vehicle passive safety device technology, and more specifically to a rear airbag, a front seat, and a vehicle. Background Technology

[0002] In vehicles, airbags are an important passive safety device that plays a crucial role in protecting occupants during collisions. Currently, the airbags commonly equipped in vehicles mainly include driver's side airbags and front passenger side airbags, which primarily provide protection for front-seat occupants in the event of a frontal collision.

[0003] However, safety protection for rear-seat occupants, especially in frontal collisions, remains relatively inadequate. Current technology faces numerous challenges in the research and application of rear-seat airbags. One prominent issue is the limited installation space in the front seats. Specifically, with the continuous development of vehicle design and consumers' increasing demands for efficient interior space utilization, vehicle interior layouts are becoming increasingly compact. Front seats must not only meet occupant comfort requirements but also integrate multiple functions such as electric adjustment, ventilation, and massage. This significantly occupies space in the front seats. Directly placing a rear-seat airbag on top of this may cause interference between the airbag and other functional components, resulting in a failure to provide the desired protection. Utility Model Content

[0004] The purpose of this utility model is to provide a rear airbag, a front seat, and a vehicle to solve the technical problem of the difficulty in installing existing rear airbags.

[0005] To achieve the above objectives, this utility model provides a rear-seat safety airbag, which is installed on the front seat. The front seat includes a backrest frame, the backrest frame includes an upper crossbeam, and the upper crossbeam has an accommodating groove. The rear-seat safety airbag is installed in the accommodating groove. The rear-seat safety airbag is configured to be triggered and inflated when the vehicle is involved in a collision, so as to support the rear occupants.

[0006] Optionally, the system includes a generator and an airbag, with a portion of the generator located inside the airbag and a portion extending outside the airbag. The portion of the generator extending outside the airbag is fixed to the upper crossbeam. The airbag is in a folded state. The generator is configured to be triggered when a vehicle collision occurs to inflate the airbag, causing the airbag to expand from the folded state to the deployed state. The airbag in the deployed state is used to accommodate rear-seat occupants.

[0007] Optionally, the generator is connected to a vehicle electronic control unit, which triggers the generator when a vehicle collision occurs.

[0008] Optionally, it also includes a dust cover that completely encloses the air bag, and the portion of the generator extending outside the air bag also extends outside the dust cover; or

[0009] The dust cover encloses a portion of the air bag, while the generator extends from the portion of the air bag not covered by the dust cover.

[0010] Optionally, the generator includes at least one stud that extends beyond the air bag for fixing to the upper crossbeam.

[0011] Optionally, the stud passes through the upper crossbeam and is secured to the upper crossbeam by a nut.

[0012] Optionally, the airbag in the deployed state is positioned above the knees of the rear passenger to support the area above the knees of the rear passenger; or

[0013] The airbag in the deployed state includes a first part and a second part. The first part is used to support the area above the knees of the rear passengers, and the second part is used to support the knees of the rear passengers.

[0014] Optionally, when the air bag includes a first part and a second part, the air bag is provided with a pull strap inside, the two ends of the pull strap are respectively fixed to the opposite sides of the second part, and the pull strap is configured to tighten as the air bag expands to limit the volume of the second part.

[0015] Another aspect of this utility model provides a front seat that includes the rear airbag described above.

[0016] In another aspect, this utility model provides a vehicle that includes the front seats as described above.

[0017] The rear airbag of this utility model is installed in the receiving groove on the upper crossbeam of the backrest frame of the front seat. The receiving groove is an additional space that does not occupy other space of the front seat. Therefore, the rear airbag will not interfere with the functional components of the front seat, and the rear airbag can be installed smoothly. Attached Figure Description

[0026] For the sake of simplicity, Figure 2 , Figure 3 and Figure 4 The image only shows the upper crossbeam of the backrest frame, without showing the functional components mounted on the backrest frame. Detailed Implementation

[0027] The preferred embodiments of this utility model are given below with reference to the accompanying drawings and described in detail.

[0028] like Figure 1 As shown, the front seats of the vehicle include a backrest frame 100, which includes an upper crossbeam 200. Functional components 300 are installed below the upper crossbeam 200, including electric adjustment components, fan components, and massage components, etc. These functional components 300 occupy most of the space of the front seats, and the remaining small space makes it difficult to properly install the rear airbags.

[0029] To solve the above problems, this utility model embodiment provides a rear-seat airbag 400, such as... Figure 2 , Figure 3 and Figure 4As shown, the rear airbag 400 is installed on the front seat. Specifically, a receiving groove 210 is provided on the upper crossbeam 200 of the front seat backrest frame 100, and the rear airbag 400 is fixed in the receiving groove 210. The receiving groove 210 is additionally provided on the upper crossbeam 200. Installing the rear airbag 400 in the receiving groove 210 does not affect the installation of the functional component 300. That is, the rear airbag 400 in the receiving groove 210 will not interfere with the functional component 300, so it can be installed smoothly. At the same time, it can also reduce the thickness and weight of the rear airbag, making it lighter and thinner. The rear airbag 400 can be connected to the vehicle electronic control unit (ECU). When the vehicle is involved in a collision, the vehicle ECU can trigger the rear airbag 400 to inflate and support the rear occupants, thereby providing collision protection for the rear occupants.

[0030] like Figure 5 and Figure 6 As shown, the rear airbag 400 includes a generator 410, an airbag 420, and a dust cover 430. At least a portion of the generator 410 is located inside the airbag 420, and a portion extends outside the airbag 420. The portion of the generator 410 extending outside the airbag 420 is fixed to the upper crossbeam 200. The airbag 420 is in a folded state, and the dust cover 430 is fitted over the outside of the airbag 420. The dust cover 430 serves two purposes: maintaining the folded posture of the airbag 420 and providing dust protection. The generator 410 is configured to inflate the airbag 420 upon activation, causing the airbag 420 to expand from the folded state to the deployed state. During the expansion process, the airbag gradually increases in volume and eventually bursts the dust cover 430. Thus, the deployed airbag 420 is positioned in front of the occupant, catching and protecting them. The generator 410 can be connected to the vehicle ECU. When a collision occurs, the vehicle ECU can send a trigger signal to the generator 410 to trigger the generator 410. After the generator 410 is triggered, it can inflate the airbag 420.

[0031] The dust cover 430 can completely enclose the air bag 420. At this time, the part of the generator 410 extending outside the air bag 420 also extends outside the dust cover 430 to be fixed to the upper crossbeam 200. Alternatively, the dust cover 430 may not completely enclose the air bag 420, but only enclose the side of the air bag 420 facing the rear passengers. The side away from the rear passengers is located in the receiving groove 210, so it does not need to be enclosed by the dust cover 430. In this case, the part of the generator 410 extending out of the air bag 420 extends from the part of the air bag 420 that is not enclosed by the dust cover 430.

[0032] It is understood that in other embodiments, the rear airbag 400 may not include the dust cover 430, but only include the generator 410 and the airbag 420, which is folded and maintained in shape by the receiving groove 210.

[0033] The generator 410 may include at least one stud 411 extending beyond the air bag 420 for fixing to the upper crossbeam 200. Figure 4 As shown, the stud 411 can pass through the upper crossbeam 200 and be fixed to the upper crossbeam 200 by the matching nut 500.

[0034] like Figure 7 As shown, the airbag 420 in the deployed state can be positioned above the knees of the rear passengers to support the area above the knees of the rear passengers (mainly the head and chest), thereby protecting the area above the knees of the rear passengers.

[0035] like Figure 8 As shown, the airbag 420 in the deployed state can also be configured to include a first part 421 and a second part 422. The first part 421 is located above the knees of the rear passenger, serving to support the area above the knees of the rear passenger, thereby protecting the area above the knees of the rear passenger. The second part 422 is located in front of and below the knees of the rear passenger, serving to support the knees of the rear passenger, thereby protecting the knees of the rear passenger. In other words, Figure 8 The airbags inside can protect the heads and knees of rear passengers simultaneously. Figure 8 Inside the airbag 420, there is a pull strap 423. The two ends of the pull strap 423 are fixed to the opposite sides of the second part 422 of the airbag 420. When folded, the pull strap 423 is in a relaxed state. As the airbag 420 gradually expands, the pull strap 423 will gradually tighten, thereby restricting the shape of the airbag 420 and preventing the second part 422 from being too large and compressing the occupant's knees.

[0036] Understandably, by designing the shape, structure, and folding method of the airbag 420, it can be made to unfold in the expected manner, thereby achieving different protective effects, for example... Figure 7 or Figure 8 The protective effect of the airbag 420 is described in detail below. The specific design of the shape, structure, and folding method of the airbag 420 to achieve the desired protective effect is existing technology in this field and will not be elaborated upon here.

[0037] The installation process of the rear airbag in this embodiment of the utility model is as follows:

[0038] Insert the generator 410 into the airbag 420 and extend the stud 411 out of the airbag 420. Then fold the airbag 420 according to the preset folding method. If the rear airbag 400 includes a dust cover 430, wrap the airbag 420 with the dust cover 430 and then place the wrapped whole into the receiving groove 210. If the rear airbag 400 does not include a dust cover 430, place the folded airbag 420 and the generator 410 together into the receiving groove 210. Regardless of whether the dust cover 430 is included, when placing the rear airbag 400 into the receiving groove 210, make sure that the part of the stud 411 is located further inside the receiving groove 210 and that the stud 411 passes through the upper crossbeam 200. Then fix the stud 411 to the upper crossbeam 200 with the nut 500. The rear airbag 400 can then be fixed to the upper crossbeam 200.

[0039] The rear airbag of this utility model embodiment is installed in the receiving groove 210 on the upper crossbeam 200 of the backrest frame 100 of the front seat. The receiving groove 210 is an additional space that does not occupy other space of the front seat. Therefore, the rear airbag will not interfere with the functional components 300 of the front seat, and the rear airbag can be installed smoothly.

[0040] This utility model embodiment also provides a front seat, which includes the rear airbag described in the above embodiment.

[0041] This utility model embodiment also provides a vehicle that includes the front seats as described above.
