Passengers can sit upright on the car seat, or they can rotate and lay down the backrest and lie on the car seat, but since the lying space is small, the lying comfort of passengers is not good.

[0004] In order to improve the lying experience of users, some car models will be equipped with a large bed mode for car seats. When using it, after removing the headrest of the front seat, the backrest is folded back to be flush with the seat of the rear seat. The seat and backrest of the front seat and the seat of the rear seat form a large bed mode. In this mode, there is a large lying space for passengers and the passengers are comfortable. However, it requires the front and rear seats to work together to form a large bed mode, and the operation of forming a bed is troublesome. Utility Model Content

[0044] Embodiment 1:

[0045] like Figure 1-Figure 5 As shown, a car seat that can be unfolded into a bed has a sleeping mode. In normal use, the car seat can be used for passengers to sit up, and when the car seat is adjusted to the sleeping mode, it can be used for passengers to lie down. The car seat of this embodiment mainly includes: a seat 1, a first backrest 2, a second backrest 3, a first support frame 30, a second support frame 4, a locking mechanism 5 and a recliner 6.

[0046] The first backrest 2 is rotatably arranged on the seat 1, specifically, the first backrest 2 is rotatably installed on the seat 1 through a manual recliner 6 or an electric recliner 6. The inclination angle of the first backrest 2 relative to the seat 1 can be adjusted by the adjuster. The second backrest 3 is movably arranged on the back side of the first backrest 2, specifically, the second backrest 3 is rotatably arranged on the back side of the first backrest 2.

[0047] Reference Figure 1-Figure 2 as well as Figure 4-Figure 5 As shown, in actual use, when the car seat is switched to the bed mode: the first backrest 2 is tilted backward relative to the seat 1, and the second backrest 3 is unfolded from the back side of the first backrest 2, so that the first backrest 2 and the second backrest 3 are flattened, and together with the seat 1, the three of them form a lying area for the passenger to lie down. After the first backrest 2 and the second backrest 3 are flattened, the seat 1, the first backrest 2 and the second backrest 3 are almost on the same plane to ensure the comfort of the passenger when lying down. Since the foaming is omitted in the diagram, they are not on the same plane.

[0048] Specifically, in the car seat of this embodiment, a first support frame 30 is provided on the second backrest 3, the first support frame 30 is fixedly connected to the second backrest 3, and the first support frame 30 is located at the lower end of the second backrest 3, and is arranged in an L shape. When the car seat is switched to the bed mode, the first support frame can be supported on the body of the car, that is, the first support frame 30 is configured as a bed support leg in the bed mode to ensure the support strength, and a plurality of first support frames 30 are arranged side by side on the second backrest 3.

[0049] More specifically, a second support frame 4 is provided between the first backrest 2 and the second backrest 3, wherein the two ends of the second support frame 4 are respectively configured as a connection end 41 and a support end 42, wherein the connection end 41 is rotatably connected to both the first backrest 2 and the second backrest 3, and the second support frame 4 is specifically provided in a T-shape, and the connection end 41 includes two connection parts 411 arranged side by side, wherein one connection part 411 is rotatably connected to the first backrest 2, and the other connection part 411 is rotatably connected to the second backrest 3. The support end 42 is a free end, which can be supported on the vehicle body through the support end 42. In actual use, when the car seat is switched to the bed mode, the second support frame 4 can be supported on the vehicle body, and the second support frame 4 is also configured as a bed support leg in the bed mode. When the car seat is folded from the bed mode, the second support frame 4 can be folded between the first backrest 2 and the second backrest 3. In addition, a plurality of second support frames 4 are arranged side by side between the first backrest 2 and the second backrest 3. Since the vehicle body is not flat, the lower ends of the first support frame 30 and the second support frame 4 are not necessarily on the same plane after unfolding. They can be adaptively arranged according to the shape of the vehicle body. The first support frame 30 and the second support frame 4 are both stamped parts, which can be made into different shapes according to different positions.

[0050] In this embodiment, when the car seat is switched to the bed mode (i.e., the large bed mode), the multiple first support frames 30 on the second backrest 3 are supported at the end of the bed, and the other end of the bed is supported by the seat 1, and the middle of the bed is supported by the multiple parallel second support frames 4 between the first backrest 2 and the second backrest 3, so as to ensure reliable support of the car seat in the bed mode, ensure structural strength, and also ensure the comfort of passengers when lying down. The first support frame 30 and the second support frame 4 are unfolded as the first backrest 2 and the second backrest 3 are flattened, and are folded as the first backrest 2 and the second backrest 3 are reset, which is simple to operate and convenient to use.

[0051] Preferably, if Figure 2 and Figure 3 As shown, in the automobile seat of this embodiment, a locking mechanism 5 is provided between the first backrest 2 and the second backrest 3, and the locking mechanism 5 can lock the second backrest 3 on the back side of the first backrest 2. When the locking mechanism 5 is unlocked, the second backrest 3 is rotated and unfolded from the back side of the first backrest 2. Among them, the locking mechanism 5 includes a latch 51 and a lock seat 50, the latch 51 is arranged on one of the first backrest 2 and the second backrest 3, and the lock seat 50 is arranged on the other of the two. That is, the latch 51 can be locked to the lock seat 50, locking the second backrest 3 on the back side of the first backrest 2; when the latch 51 is unlocked from the lock seat 50, the second backrest 3 can be rotated and unfolded from the back side of the first backrest 2.

[0052] In actual use, the car seat of this embodiment has a first backrest 2 that is rotatably arranged on the seat 1, and a second backrest 3 is movably arranged on the back side of the first backrest 2. When the first backrest 2 is turned backward and the second backrest 3 is unfolded from the back side of the first backrest 2, the seat 1, the first backrest 2 and the second backrest 3 form a lying area for passengers to lie down, that is, the car seat is unfolded into a bed and switched to a sleeping bed mode (i.e., a large bed mode). The car seat itself can be unfolded into a bed without the front and rear seats being coordinated to form a bed, and the operation of unfolding into a bed is simple. After the car seat is folded from the sleeping bed mode, it occupies a small space, which can improve the room rate in the car.

[0053] Embodiment 2:

[0054] like Figure 6 Combined with Figure 1-Figure 5 As shown, a car seat system of this embodiment includes a plurality of car seats that can be unfolded into a bed in the first embodiment arranged side by side. The car seat system, wherein the plurality of car seats that can be unfolded into a bed arranged side by side, when all of them are unfolded into a bed, can further increase the width of the bed, provide a larger lying space for passengers, and thus improve the comfort of passengers.
