Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology, specifically relating to a collision-resistant rear automotive seat. Background Technology

[0002] Existing airbags are generally located inside the driver's side steering wheel and in front of the passenger side, as well as on the sides of the front seatbacks. They can absorb the impact of the occupants. Rear airbags are generally installed on both sides of the seatbacks. However, these rear airbags can only protect occupants from the impact of interior parts intruding due to door deformation after a side impact. If there are multiple passengers in the rear seats when the vehicle is hit by a side impact, there will be violent collisions between the passengers, resulting in serious injuries or fatalities.

[0003] Patent application CN201811059402.3 discloses a rear seat comprising a left seat, a middle seat, and a right seat. An airbag is installed in the backrest area of ​​the middle seat. In the event of a side collision, the airbag deploys to separate the passengers on the left and right seats, preventing collisions between them. While this solution offers some protection in certain scenarios, the airbag's placement primarily protects the torso upon deployment. Since injuries and fatalities often result from head impacts, the actual protective effect is limited. Furthermore, this solution only provides protection when there are two passengers in the rear seats; it completely loses its protective effect when there are three passengers, severely limiting its applicability. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides a rear-seat car seat designed to prevent collisions. This rear-seat car seat can deploy airbags between rear passengers in the event of a side impact, preventing head injuries and reducing the risk of fatalities. It provides protection even when there are two or three passengers in the rear, making it suitable for a wider range of scenarios.

[0005] A collision-resistant rear car seat includes two main seats and a connecting seat disposed between the two main seats. The connecting seat includes a first backrest and a first headrest connected to the upper end of the first backrest. The interior of the first headrest has a front reserved cavity near the two main seats. The front reserved cavity forms a front opening in the front direction of the first headrest. A removable front protective plate is encapsulated at the front opening. A front airbag assembly is disposed in each of the front reserved cavities.

[0006] Furthermore, a raised pad is connected to the center of the front side of the first headrest, the front reserved cavity is offset from the pad, and an outward protrusion is formed on each side of the pad near the two main seats, with an inward concave portion between the two outward protrusions.

[0007] Furthermore, the distance between the upper and lower edges of the front opening is greater than the distance between the left and right edges, and the shape of the front airbag assembly is adapted to the front opening.

[0008] Furthermore, the first headrest and the first backrest are fixedly connected by a connecting post.

[0009] Furthermore, the main seat includes a second backrest and a second headrest connected to the upper end of the second backrest. The interior of the second headrest has a back-side reserved cavity, and the back-side reserved cavity forms a back-side opening in the back-side direction of the second headrest. A removable back-side protective plate is encapsulated at the back-side opening, and a back-side airbag assembly is provided in the back-side reserved cavity.

[0010] Furthermore, the distance between the upper and lower edges of the rear opening is smaller than the distance between the left and right edges, and the shape of the rear airbag assembly is adapted to the rear opening.

[0011] Furthermore, the back protective plate includes an upper plate and a lower plate. The lower edge of the upper plate is provided with a connecting clip, and the upper edge of the lower plate is provided with a connecting slot. The connecting clip engages with the connecting slot.

[0012] Furthermore, the second backrest and the second headrest are connected to each other by a connecting seat. The connecting seat includes a lower connecting seat connected to the second backrest and an upper connecting seat connected to the second headrest. The lower connecting seat and the upper connecting seat are fixedly connected by a buffer bolt. The buffer bolt contains foam pores or honeycomb holes inside.

[0013] Furthermore, the lower connecting seat has a supporting curved surface facing the back of the second headrest, and the upper connecting seat has a mating curved surface facing the front of the second headrest that corresponds to the shape of the supporting curved surface. The supporting curved surface and the mating curved surface overlap and fit together, and the buffer bolt passes through the supporting curved surface and the mating curved surface.

[0014] Furthermore, the upper end of the supporting surface extends towards the front of the second headrest and the horizontal slope gradually decreases, while the lower end of the supporting surface extends towards the back of the second headrest and the horizontal slope gradually decreases.

[0015] The following beneficial effects can be achieved by applying this utility model: 1. This utility model has two front airbag components on the first headrest of the connecting seat. When the vehicle is subjected to a side impact, the front airbag components in the two reserved cavities expand forward and push open the front protective plate, forming a protective airbag at the junction of the left main seat and the connecting seat and the right main seat and the connecting seat. It can play a protective role when there are two or three rear passengers. Since the protective airbags deploy from the headrest, they can separate the passengers' heads immediately and avoid head collisions that could cause injury.

[0016] 2. In some embodiments of this utility model, a pad is provided on the front side of the first headrest. The pad is used to position and protect the head of the passenger on the connected seat. When the passenger's headrest rests on the pad, the front airbag assembly will not hit the passenger's head when it expands and deploys.

[0017] 3. In some embodiments of this utility model, the second headrest is provided with a back-side airbag assembly. When the vehicle collides, the back-side airbag assembly expands and deploys on the back side of the seat, which can prevent fragments generated at the rear windshield from hitting the rear passengers.

Detailed Implementation

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0020] Reference Figures 1-4 One embodiment of the present invention provides a collision-resistant rear car seat, which includes two main seats 2 and a connecting seat 1 disposed between the two main seats; The connecting seat 1 includes a first backrest 11 and a first headrest 12 connected to the upper end of the first backrest. The first backrest and the first headrest are fixedly connected by a connecting post 13. Each of the first headrest 12 has a front-side reserved cavity 121 located near the two main seats 2. The front-side reserved cavity 121 forms a front-side opening in the front direction of the first headrest 12. A removable front-side protective plate 122 is encapsulated at the front-side opening. Each front-side reserved cavity is equipped with a front-side airbag assembly 123. When the vehicle is impacted, the front-side airbag assembly inflates and deploys, pushing open the front-side protective plate 122 and forming a protective airbag at the junction of the connecting seat and the main seats, separating the passengers on the main seats and the connecting seats. Since the airbag deploys from the first headrest, it can provide immediate head protection, reducing accident injuries and fatalities. Figure 2 In this embodiment, the front opening is rectangular, with its vertical height greater than its horizontal width. The shape of the front airbag assembly is adapted to the front opening, and the airbag forms a longitudinal cylindrical structure after deployment, giving it a large coverage area in the longitudinal direction to accommodate passengers of different heights. To further improve the safety of the front airbag assembly, in some embodiments, a pad 124 is connected to the front of the first headrest. The pad 124 is located in the middle of the first headrest and is offset from the two front reserved cavities, so that the pad does not obstruct the deployment of the front airbag assembly. The pad forms an outward protrusion on each side of the two main seats 1, and an inward concave portion is provided between the two outward protrusions. The pad can guide the passenger to rest the headrest against the inward concave area, avoiding impact on the passenger's head when the front airbag assembly expands and deploys. The main seat 2 includes a second backrest 21 and a second headrest 22 connected to the upper end of the second backrest. A back-side reserved cavity 221 is formed inside the second headrest 22. The back-side reserved cavity 221 forms a back-side opening in the back-side direction of the second headrest. A removable back-side protective plate 222 is encapsulated at the back-side opening. A back-side airbag assembly 223 is disposed in the back-side reserved cavity. Taking the back-side airbag assembly as an example, in this invention, the airbag assembly includes an airbag body 2231 and a gas generator 2232 disposed inside the airbag body. When the vehicle is impacted, the substance filled in the gas generator decomposes and generates a large amount of gas to penetrate the airbag body 2231. The airbag body 2231 is inflated by filling, which in turn pushes open the back side protective plate 222, forming a protective airbag on the back side of the second headrest. This protective airbag is used to prevent debris from flying towards the passenger's head from the direction of the rear windshield. To improve its protective effect, the lateral width of the back side opening is greater than its vertical height, so that the protective airbag has a larger coverage area in the lateral direction to adapt to the spatial shape of the trunk and block debris from the back side as much as possible. In a preferred embodiment, the back side protective plate 222 includes an upper plate 2221 and a lower plate 2222. The lower edge of the upper plate is provided with a connecting clip 2224, and the upper edge of the lower plate is provided with a connecting clip 2224. A connecting slot 2223 is provided, and the connecting head engages with the connecting slot. When the rear airbag assembly inflates, the connecting head breaks, and the upper and lower plates separate and are ejected. In some preferred embodiments, the second backrest and the second headrest are connected to each other via a connecting seat 23. The connecting seat includes a lower connecting seat 231 connected to the second backrest and an upper connecting seat 232 connected to the second headrest. The lower and upper connecting seats are fixedly connected by a buffer bolt 233. The buffer bolt 233 contains foam pores or honeycomb holes inside, so that the buffer bolt can play a certain buffering role through its own deformation when the vehicle is impacted. In a further preferred embodiment... The lower connecting seat 231 has a supporting curved surface facing the back of the second headrest, and the upper connecting seat 232 has a mating curved surface facing the front of the second headrest that corresponds to the shape of the supporting curved surface. The supporting curved surface and the mating curved surface overlap and fit together. The buffer bolt passes through the supporting curved surface and the mating curved surface. The upper end of the supporting curved surface extends towards the front of the second headrest and the horizontal slope gradually decreases. The lower end of the supporting curved surface extends towards the back of the second headrest and the horizontal slope gradually decreases. The above-mentioned curved surface structure is used to buffer the interaction force generated by the impact between the upper connecting seat and the lower connecting seat. The impact energy can be dissipated by sliding between the upper connecting seat and the lower connecting seat.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
