Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to an improved structure for the suspension installation of an automobile seat backrest. Background Art

[0002] The suspension structure of the seat back is an important component of the car seat. It is used to support the back of the passenger when sitting, and is usually composed of steel wire. A Chinese patent (authorization announcement number: CN214057323U) discloses a backrest suspension structure, which supports the back of the passenger when sitting by installing a backrest suspension between the two side panels of the backrest frame. However, in actual use, when the passenger sits on the seat, the pressure applied to the backrest suspension by different areas of the back is different. The backrest suspension only plays a simple supporting role for the back of the human body. Under long-term use, the passenger will feel very uncomfortable in the back muscles and the comfort is poor. According to the comfort requirements, the rigidity of the upper part of the backrest suspension should be weaker, and the rigidity of the lower part should be stronger. The upper part will deform more after the passenger sits, and the comfort will be better. Utility Model Content

[0003] In view of the problems existing in the above-mentioned prior art, the utility model aims to provide an improved structure for the suspension installation of a car seat backrest, so that the suspension structure is more ergonomic and effectively improves the riding comfort of passengers.

[0004] In order to achieve the above-mentioned purpose, the utility model proposes an improved structure for the installation of a car seat back suspension, including a back suspension and two back side panels, the middle part and the bottom part of both sides of the back suspension are provided with wire hooks, the back suspension is hooked between the two back side panels through the wire hooks, and also includes two tension springs, the two tension springs are arranged one by one at the top of both sides of the back suspension, the back side panels are provided with mounting holes at the positions of the tension springs on the same side, a locking bolt is inserted in the mounting hole, and an anti-slip seat is provided on the outer side of the locking bolt to prevent it from slipping out of the back side panel inwardly, and the other ends of the two tension springs are fixed to the corresponding side locking bolt.

[0005] In the above scheme: the mounting hole is a strip hole, the locking bolt is a U-shaped piece, the locking bolt can just pass through the strip hole, the anti-slip seat is arranged on the two legs of the locking bolt, and the tension spring is hooked and fixed on the head of the locking bolt. The anti-slip seat is located on the outer side of the backrest side plate, the locking bolt includes two legs and a head connecting the two legs, and the head of the locking bolt is located on the inner side of the backrest side plate, which has a simple structure and is easy to process.

[0006] In the above scheme: the two legs of the locking bolt have a restoring elastic force when they are pressed and closed, and the locking bolt is clamped in the strip hole by the restoring elastic force, which is beneficial to ensure the assembly stability of the locking bolt and the side plate of the backrest and avoid abnormal noise caused by friction.

[0007] In the above scheme: the two legs of the locking bolt are provided with slots at positions corresponding to the side panels of the backrest, and the locking bolt is connected to the side panels of the backrest through the slots to achieve lateral limitation, further preventing the locking bolt from escaping laterally.

[0008] In the above scheme: the wire hook is formed by extending and bending the transverse wire on the backrest suspension outward, which has a simple structure and is easy to process.

[0009] The beneficial effects of the utility model are as follows: 1. By replacing the top of the two sides of the backrest suspension hooked between the two backrest side panels with steel wire hooks, the top of the backrest suspension hooked between the two backrest side panels is hooked between the two backrest side panels through tension springs, thereby reducing the rigidity of the upper part of the backrest suspension, so that the deformation of the upper part of the backrest suspension after the passenger sits is increased, that is, the embedding amount of the upper end of the passenger's back is increased, making the suspension structure more ergonomic and effectively improving the passenger's riding comfort. 2. The installation structure design of the tension spring and the backrest side panels is ingenious and easy to disassemble and assemble. BRIEF DESCRIPTION OF THE DRAWINGS

The anti-slip seat 61 is located on the outer side of the backrest side plate 2, the locking bolt 6 includes two legs and a head connecting the two legs, and the head of the locking bolt 6 is located on the inner side of the backrest side plate 2, which has a simple structure and is easy to process.

[0017] Preferably, the two legs of the locking member 6 have a restoring elastic force when they are pressed and closed, and the locking member 6 is clamped in the strip hole by the restoring elastic force, which is conducive to ensuring the assembly stability of the locking member 6 and the backrest side panel 2 and avoiding abnormal noise caused by friction.

[0018] Preferably, two legs of the locking bolt 6 are provided with slots 62 at positions corresponding to the backrest side panels 2 , and the locking bolt 6 is connected to the backrest side panels 2 through the slots 62 to achieve lateral limitation, further preventing the locking bolt 6 from escaping laterally.

[0019] Preferably, the wire hook 3 is formed by extending and bending the transverse wire on the backrest suspension 1 outward, which has a simple structure and is easy to process.
