[0034] To make the technical solutions and advantages of the present invention more clearly understood, exemplary embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It should be understood that the described embodiments are only a portion of the embodiments of the present invention, and are not exhaustive. Furthermore, the embodiments and features of the embodiments of the present invention may be combined with each other unless there is a conflict.

[0035] It should be noted that the terms "first", "second", etc. in this application are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0036] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art can understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0037] The embodiment of the present invention provides a car seat. Figure 1As shown, the car seat includes a first backrest 1, a first seat cushion 2, and a safety belt guide ring 3. The first backrest 1 and the first seat cushion 2 match to form a seat for a passenger. The safety belt guide ring 3 is fixed to the upper end of the first backrest 1. The safety belt guide ring 3 is used to pass a safety belt 4 through and guide the safety belt 4. According to the present application, multiple different working positions are provided on the first seat cushion 2, allowing the first backrest 1 to be moved and positioned at different working positions. This allows the first backrest 1 to be adjusted in the fore-and-aft direction of the first seat cushion 2. As the first backrest 1 moves forward, its height decreases. The safety belt guide ring 3 on the first backrest 1 also decreases, making the seat formed by the first seat cushion 2 and the first backrest 1 at that position more adaptable to children's height. Thus, the car seat of the present application has different working conditions and is suitable for people of different heights, effectively ensuring the safety of children. With the car seat of the present application, users do not need to purchase additional child safety seats, reducing living costs. In addition, the application can adapt to people of different heights by moving the first backrest 1, and has a simple structure and is easy to manufacture.

[0038] Specifically, a height-adjustable seat 5 is provided at some workstations for adjusting the height of the first backrest 1. During use, the height-adjustable seat 5 is attached to the first seat cushion 2, while the first backrest 1 is attached to the height-adjustable seat 5 to raise the height of the first backrest 1. This structure is simple and easy to implement. As will be understood, the lateral dimensions of the height-adjustable seat 5 are designed to match the first backrest 1, while the vertical height is designed to adjust the height of the first backrest 1 relative to the first seat cushion 2.

[0039] It should be noted that the figures of this application only show an embodiment in which the first backrest 1 has two working positions. Specifically, Figure 1 In the figure, the first backrest 1 is located in the original position, and a height adjustment seat 5 is provided between the first backrest 1 and the first seat cushion 2 to make the position more suitable for adults. Figure 3 In the embodiment, the first backrest 1 is moved to the position shown, and the height of the first backrest 1 relative to the first seat cushion 2 is lowered to make the safety belt 4 more suitable for the child. However, it is understandable that the present application is not limited to the above-mentioned technical solution of the first backrest 1 having two positions. That is to say, according to different needs, the first backrest 1 can also have more positions on the first seat cushion 2, such as three or four. In addition, since the figures of the present application only show an embodiment in which the first backrest 1 has two positions, the height adjustment seat 5 (such as Figure 1 As shown), while in another station, the first backrest 1 is directly set on the first seat cushion 2 (as shown Figure 3As shown). It will be understood by those skilled in the art that if it is desired to ensure that the first backrest 1 has more positions on the first seat cushion 2, a height adjustment seat 5 may be added at an appropriate position on the first seat cushion 2. For example, Figure 1 and Figure 3 If one more station is added between the two stations shown, a larger Figure 1 The slightly shorter height adjustment seat 5 shown is used to more precisely adjust the height of the first backrest 1 relative to the first seat cushion 2 to meet the needs of three different heights: adults, children, and infants. Of course, to ensure that the car seat can function normally in the initial position, the height adjustment seat 5 at the additional position can be detachably connected to the first seat cushion 2 so that it can be removed from the first seat cushion 2 when not needed, while ensuring the flatness and comfort of the first seat cushion 2.

[0040] The first backrest 1 and the first seat cushion 2, or the first backrest 1 and the height adjustment seat 5 are configured as a plug-in connection, such as Figure 2 As shown. Specifically, a latch 6 is provided at the lower end of the first backrest 1. A latch fixing seat 7 is provided on both the first seat cushion 2 and the height adjustment seat 5. By inserting the latch 6 into different latch fixing seats 7, the position of the first backrest 1 relative to the first seat cushion 2 can be adjusted. In other words, the first backrest 1 is set to different workstations or removed from different workstations by plugging and unplugging. The above arrangement can ensure that the workstations of the first backrest 1 can be quickly adjusted to meet the different needs of passengers. At least two latches 6 are provided at intervals at the lower end of the first backrest 1. The latch fixing seats 7 on the first seat cushion 2 and the height adjustment seat 5 are adapted to the latch 6 in terms of quantity and position.

[0041] In one embodiment, the latch 6 is configured as a tube. Figure 6 As shown. Of course, the latch 6 can also be constructed in a cylindrical or rod-like shape. However, a tubular latch 6 meets the required strength while being lightweight and facilitating the movement of the first backrest 1. Preferably, the lower end of the latch 6 is tapered to facilitate insertion into the height adjustment seat 5 and guide the latch 6 body for positioning.

[0042] like Figures 4 to 6As shown, the latch fixing seat 7 has a fixing seat body 71 and a fixing seat head 72. The fixing seat body 71 is cylindrical in structure, mainly used to accommodate the latch 6 and form a plug-in fit with the latch 6. The fixing seat head 72 is arranged at the upper end of the fixing seat body 71, and its axial cross-sectional area is increased relative to the fixing seat body 71. At the same time, the fixing seat head 72 is connected to the fixing seat body 71. In other words, the latch fixing seat 7 is generally constructed as a hollow T-nail type, which is used to be installed and fixed to the first seat cushion 2 and the height adjustment seat 5. The fixing seat body 71 is buried in the first seat cushion 2 and the height adjustment seat 5, and the fixing seat head 72 is generally flush with the surface of the corresponding first seat cushion 2 and the height adjustment seat 5.

[0043] Preferably, a circumferentially closed protruding ring 73 is provided on the outer wall of the fixed seat body 71. The protruding ring 73 is provided at approximately the middle axial position of the fixed seat body 71. The protruding ring 73 is mainly used to increase the axial friction force. When the latch 6 is removed, the protruding ring 73 can prevent the fixed seat body 71 from falling off the first seat cushion 2 and the height adjustment seat 5. In addition, an axially extending first protruding strip 74 is provided between the protruding ring 73 and the fixed seat head 72. There are multiple first protruding strips 74 and they are spaced apart in the circumferential direction. In addition, a second protruding strip 75 is provided on the outer wall of the fixed seat body 71. One end of the second protruding strip 75 is fixed to the protruding ring 73, while the other end extends downward. The second protruding strip 75 is staggered in the circumferential direction from the first protruding strip 74. The lower end of the second protruding strip 75 is provided with a tapered surface to transitionally connect the second protruding strip 75 and the fixed seat body 71. A third protruding strip 76 is provided between the two spaced-apart second protruding strips 75. This third protruding strip 76 is axially opposed to the first protruding strip 74, and its upper end abuts against the protruding ring 73. The provision of the first, second, and third protruding strips 74, 75, and 76 increases the frictional force of the fixing seat body 71 in the circumferential direction, preventing the fixing seat body 71 from rotating circumferentially relative to the fixed position, thereby ensuring its stable fixation. This also helps to increase the strength of the fixing seat body 71, thereby extending its service life.

[0044] A dust cover 8 is optionally provided at the opening of the fixed seat head 72. This dust cover 8 is used to cover the latch fixed seat 7 (not provided with the first backrest 1) to prevent foreign matter from entering the fixed seat body 71. An operating slot 77 is provided on the fixed seat head 72. When the dust cover 8 covers the opening of the fixed seat head 72, the dust cover 8 protrudes into the operating slot 77. The provision of the operating slot 77 facilitates the installation and removal of the dust cover 8.

[0045] Preferably, the first backrest 1 can be set in the back row of the car and located in the middle of the car seat. That is to say, the car seat also includes a second backrest 9 and a second seat cushion 10 matched with the second backrest 9. There are two second backrests 9, which are distributed on the left and right ends of the first backrest 1. There are also two second seat cushions 10, which are respectively set on the left and right ends of the first seat cushion 2. On the one hand, the above-mentioned arrangement optimizes the structure of the car seat itself. For example, compared with the height adjustment seat 5 being set at the left and right ends, the height adjustment seat 5 being set in the middle structure is simpler; on the other hand, it is relatively safer to place the child in the middle position of the car seat. Of course, according to different needs, the above-mentioned first backrest 1 and first seat cushion 2 can be set on the left or right. In addition, the other backrests and seat cushions of the car seat can also be constructed in a structural form similar to the first backrest 1 and first seat cushion 2.

[0046] As will be appreciated, one end of the safety belt 4 is provided on a retractor 11 which can be mounted on the body of the vehicle, while the other end of the safety belt 4 passes through the safety belt guide ring 3 for being clipped onto a safety belt clip (not shown) when needed.

[0047] The car seat of the present application can be adjusted to accommodate passengers of different sizes, thereby avoiding the need to prepare an additional baby seat and reducing the user's car investment. In addition, the car seat has a simple structure, is easy to adjust, and is easy to operate.

[0048] In this application, the directional terms "front", "rear", "left", "right", "up" and "down" are all with reference to the automobile.
