Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a rear seat back frame for automobiles. Background Technology

[0002] In modern automotive design, the seating system is a crucial component ensuring passenger comfort and safety. As a core structural component of the seat assembly, the backrest frame's primary function is to provide stable posture support during vehicle cornering and to offer necessary protection for the upper body of passengers in the event of a collision. The performance of the backrest frame directly affects the strength and rigidity of the seat assembly, and even the overall quality and grade of the vehicle.

[0003] Traditionally, the rear seatback frames of cars are welded directly to the vehicle frame during installation. This fixed installation method prevents the rear seats from folding down, thus limiting the usable space in the trunk. When passengers need to carry large luggage or other bulky items, the trunk space is often insufficient, making loading and unloading inconvenient and restricting the vehicle's versatility and practicality. Utility Model Content

[0004] The purpose of this utility model is to provide a car rear seat back frame, which aims to solve the problem that the rear seats cannot be folded because the traditional car rear seat back frame is directly welded to the vehicle frame during installation.

[0005] To achieve the above objectives, this utility model provides a rear seat back frame for automobiles, including a back frame, two buffer connectors, two mounting brackets, two fixing brackets, two snap-fit ​​components, and two pulling components.

[0006] Two buffer connectors are respectively installed on both sides of the back frame, two mounting brackets are respectively fixedly connected to the back frame and located on the back frame, two fixing brackets are respectively fixedly connected to the two mounting brackets and located on the two mounting brackets, two snap-fit ​​pieces are respectively installed on the two fixing brackets, and two pull pieces are respectively installed on the two snap-fit ​​pieces.

[0007] The buffer connector includes a connector head and a buffer spring. The connector head is fixedly connected to the back frame and located on one side of the back frame. The buffer spring is fixedly connected to the connector head and the back frame, and located between the back frame and the connector head.

[0008] The snap-fit ​​component includes a rotating shaft and a snap fastener. The rotating shaft is fixedly connected to the fixing frame and is located on the fixing frame. The snap fastener is fixedly connected to the rotating shaft and is located on the rotating shaft.

[0009] The pulling component includes a pull head and a pull cable. The output end of the pull cable is fixedly connected to the buckle and to the mounting bracket, and is located on the mounting bracket. The pull head is fixedly connected to the other output end of the pull cable and is located on the side of the pull cable away from the buckle.

[0010] The rear seatback frame of the car also includes multiple longitudinal reinforcing ribs, two reinforcing rods, and two transverse reinforcing ribs. The multiple longitudinal reinforcing ribs are fixedly connected to the backrest frame and are all located on the backrest frame. The two reinforcing rods are fixedly connected to the backrest frame and are all located on the backrest frame. The two transverse reinforcing ribs are fixedly connected to the two reinforcing rods and are located on the two reinforcing rods respectively.

[0011] This utility model discloses a rear seat backrest frame for automobiles. The backrest frame provides installation conditions for two buffer connectors and two mounting brackets. The two buffer connectors connect the backrest frame to the vehicle body, and the two mounting brackets provide installation conditions for two snap-fit ​​components. When the backrest frame needs to be folded, the two pulling components are pulled, causing the two snap-fit ​​components to rotate away from the fixed bracket until the snap-fit ​​components and the fixed bracket open. Then, the backrest frame is pulled and rotated along the two buffer connectors towards the seat cushion, thus completing the folding of the backrest frame. This solves the problem that traditional rear seat backrest frames are directly welded to the vehicle frame during installation, making it impossible to fold the rear seats.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please see Figures 1-4 This utility model provides a car rear seat back frame, including a back frame 1, two buffer connectors, two mounting brackets 2, two fixing brackets 3, two snap-fit ​​components and two pulling components;

[0020] Two buffer connectors are respectively installed on both sides of the back frame 1. Two mounting brackets 2 are respectively fixedly connected to the back frame 1 and are respectively located on the back frame 1. Two fixing brackets 3 are respectively fixedly connected to the two mounting brackets 2 and are respectively located on the two mounting brackets 2. Two snap-fit ​​pieces are respectively installed on the two fixing brackets 3. Two pull pieces are respectively installed on the two snap-fit ​​pieces.

[0021] In this embodiment, the backrest 1 provides installation conditions for the two buffer connectors and the two mounting brackets 2. The backrest 1 can be connected to the vehicle body through the two buffer connectors, and the two mounting brackets 2 provide installation conditions for the two snap-fit ​​components. When the backrest 1 needs to be folded, the two pulling components are pulled, and the two pulling components drive the two snap-fit ​​components to rotate away from the fixing bracket 3 until the snap-fit ​​components and the two fixing brackets 3 open. Then, the backrest 1 is pulled and rotated along the two buffer connectors towards the side closer to the seat cushion, thus completing the folding of the backrest 1. This solves the problem that the traditional car rear seat backrest frame is directly welded to the vehicle frame during installation, which makes the rear seats unable to be folded.

[0022] Furthermore, the buffer connector includes a connector 4 and a buffer spring 5. The connector 4 is fixedly connected to the back frame 1 and is located on one side of the back frame 1. The buffer spring 5 is fixedly connected to the connector 4 and the back frame 1, and is located between the back frame 1 and the connector 4.

[0023] In this embodiment, the back frame 1 can be connected to the vehicle body via the connector 4, and the buffer spring 5 can buffer and limit the back frame 1.

[0024] Furthermore, the snap-fit ​​component includes a rotating shaft 6 and a buckle 7. The rotating shaft 6 is fixedly connected to the fixing frame 3 and is located on the fixing frame 3. The buckle 7 is fixedly connected to the rotating shaft 6 and is located on the rotating shaft 6.

[0025] In this embodiment, the rotating shaft 6 provides installation conditions for the buckle 7, allowing the buckle 7 to rotate. The buckle 7, in conjunction with the fixing frame 3, can fix the back frame 1 to the vehicle body.

[0026] Furthermore, the pulling component includes a pull head 8 and a pull cable 9. The output end of the pull cable 9 is fixedly connected to the buckle 7 and fixedly connected to the mounting bracket 2, and is located on the mounting bracket 2. The pull head 8 is fixedly connected to the other output end of the pull cable 9 and is located on the side of the pull cable 9 away from the buckle 7.

[0027] In this embodiment, pulling the pull head 8 can cause the pull cable 9 to extend or retract, and the extension or retraction of the pull cable 9 can cause the buckle 7 to rotate.

[0028] Furthermore, the rear seatback frame of the car also includes multiple longitudinal reinforcing ribs 10, two reinforcing rods 11, and two transverse reinforcing ribs 12. The multiple longitudinal reinforcing ribs 10 are respectively fixedly connected to the back frame 1 and are all located on the back frame 1. The two reinforcing rods 11 are respectively fixedly connected to the back frame 1 and are all located on the back frame 1. The two transverse reinforcing ribs 12 are respectively fixedly connected to the two reinforcing rods 11 and are respectively located on the two reinforcing rods 11.

[0029] In this embodiment, the support strength of the back frame 1 can be improved by the multiple longitudinal reinforcing ribs 10 and the two reinforcing rods 11, and the support strength of the two reinforcing rods 11 can be improved by the two transverse reinforcing ribs 12.

[0030] When the backrest 1 needs to be folded, pull the two pull heads 8. The two pull heads 8 cause the two pull cables 9 to retract. The two pull cables 9 cause the two buckles 7 to rotate on the two rotating shafts 6 away from the fixed frame 3 until the two buckles 7 open at the locking points of the two fixed frames 3. Then pull the backrest 1 and rotate it along the two connecting heads 4 towards the side closer to the seat cushion. This completes the folding of the backrest 1, thus solving the problem that the rear seats cannot be folded because the traditional car rear seat backrest frame is directly welded to the vehicle frame during installation.
