Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an unlocking structure for a car seat back strap. Background Technology

[0002] With the continuous development of the automotive industry, the design of car seats is increasingly focusing on humanization, convenience, and safety. As a key part of seat adjustment functions, the seat back unlocking mechanism has evolved from a simple mechanical structure to a complex electronic system.

[0003] The existing car seat backrest pull strap unlocking structure uses buttons riveted to the pull strap to prevent it from falling into the backrest. When the backrest is unlocked, the pull rod will collide with the frame and produce abnormal noise. Utility Model Content

[0004] The purpose of this utility model is to provide a car seat back strap unlocking structure, which aims to solve the problem that the pull rod will collide with the frame and produce abnormal noise when unlocking the existing car seat back strap unlocking structure.

[0005] To achieve the above objectives, this utility model provides a car seat backrest pull strap unlocking structure, including a pull strap, a rubber plate, a cover, a backrest, and a pull rod; the cover is disposed on one side of the backrest, the pull strap is disposed on both the cover and one side of the backrest, the pull rod is disposed on the side of the pull strap away from the cover, and the rubber plate is fixedly connected to the pull strap and located inside the pull strap.

[0006] The cover has a cover opening located on the side of the cover away from the backrest.

[0007] The pull strap includes a pull strap body and a rejoining block. The pull strap body is disposed on one side of the cover and the backrest. The rejoining block is fixedly connected to the pull strap body and is located on the side of the pull strap body away from the pull rod.

[0008] The pull strap body has a screen printing, which is located on one side of the pull strap body.

[0009] The backrest includes a backrest body, a connecting plate, and a fixing bolt. The backrest body is located on one side of the decorative cover, the connecting plate is located on the side of the backrest body away from the decorative cover, and the fixing bolt is threadedly connected to the backrest body and passes through the connecting plate.

[0010] This utility model discloses a car seat backrest pull strap unlocking structure. The decorative cover is used to decorate the backrest, making it more aesthetically pleasing and improving its practicality. A PE plastic sheet is sewn into the middle of the pull strap. The plastic sheet restricts the rotation range of the pull rod within the decorative cover, thus reducing the rotation range of the pull rod and preventing it from hitting the backrest frame and causing abnormal noise when rotating. Furthermore, the optimized process reduces costs and solves the problem of existing car seat backrest pull strap unlocking structures where the pull rod hits the frame and causes abnormal noise when unlocking.

[0017] 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.

[0018] Please see Figures 1 to 4 This utility model provides a car seat backrest pull strap unlocking structure, including a pull strap 1, a rubber plate 2, a cover 3, a backrest 4, and a pull rod 5; the cover 3 is disposed on one side of the backrest 4, the pull strap 1 is disposed on one side of the cover 3 and the backrest 4, the pull rod 5 is disposed on the side of the pull strap 1 away from the cover 3, and the rubber plate 2 is fixedly connected to the pull strap 1 and located inside the pull strap 1.

[0019] In this embodiment, the cover 3 is used to decorate the backrest 4, making the backrest 4 more aesthetically pleasing and improving its practicality. The pull strap 1 has a plastic sheet 2 sewn in the middle. The plastic sheet 2 is a PE plastic sheet. The rotation range of the plastic sheet 2 within the cover 3 is limited, which makes the rotation range of the pull rod 5 smaller. This avoids the pull rod 5 touching the frame of the backrest 4 and causing abnormal noise when it rotates. Furthermore, the process is optimized, the cost is reduced, and the problem of the pull rod hitting the frame and causing abnormal noise when unlocking is solved in the existing car seat backrest pull strap unlocking structure.

[0020] Furthermore, the cover 3 has a cover opening 6, which is located on the side of the cover 3 away from the backrest 4.

[0021] In this embodiment, the opening 6 of the decorative cover facilitates the pull strap 1 to pass through the decorative cover 3 and the backrest 4 to complete the installation of the pull strap 1.

[0022] Furthermore, the pull strap 1 includes a pull strap body 7 and a rejoining block 8. The pull strap body 7 is disposed on one side of the cover 3 and the backrest 4. The rejoining block 8 is fixedly connected to the pull strap body 7 and is located on the side of the pull strap body 7 away from the pull rod 5.

[0023] In this embodiment, the pull strap body 7 provides installation conditions for the pull strap body 7 and the rejoining block 8. The rejoining block 8 is provided to prevent the pull strap body 7 from falling into the backrest 4 (or being accidentally inserted into the backrest 4 by a child), thus making it impossible to unlock.

[0024] Furthermore, the pull strap body 7 has a silkscreen 9, which is located on one side of the pull strap body 7.

[0025] In this implementation, the silkscreen 9 is double-sided and red, which can warn the user whether the lock on the backrest 4 is locked (the visible warning sign (silkscreen 9) means it is not locked, and the invisible warning sign means it is locked).

[0026] Furthermore, the backrest 4 includes a backrest body 10, a connecting plate 11, and a fixing bolt 12. The backrest body 10 is disposed on one side of the decorative cover 3, the connecting plate 11 is disposed on the side of the backrest body 10 away from the decorative cover 3, and the fixing bolt 12 is threadedly connected to the backrest body 10 and passes through the connecting plate 11.

[0027] In this embodiment, the connecting plate 11 is fixed to the frame by bolts, and the fixing bolt 12 is used to fix the backrest body 10 to the connecting plate 11, thereby realizing the installation and fixing of the backrest body 10.

[0028] The above-disclosed embodiments are merely preferred embodiments of the car seat backrest pull strap unlocking structure of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments, and equivalent variations made in accordance with the claims of this application, still fall within the scope of this application.
