TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile seat, especially relates to a suspension mounting structure of automobile seat backrest. BACKGROUND

[0002] The fixing mode of the traditional automobile seat backrest suspension mounting structure at the bottom of both ends usually adopts the design of steel wire hooks hooked on the two backrest side plates. This installation mode, in the early stage of automobile seat design, meets the use demand of the automobile seat at that time to some extent due to its relatively simple structure and convenient installation. However, with the continuous progress of automobile technology and the improvement of the requirements of consumers for the utilization of the interior space of the automobile and the riding comfort, the limitations of this traditional installation mode gradually become prominent. In recent years, in order to improve the utilization rate of the interior space of the automobile and meet the demand of consumers for a more spacious riding environment, automobile manufacturers require the thickness of the backrest assembly of the automobile seat in the X direction (i.e. the front-rear direction of the vehicle) to be narrower and narrower. This design trend directly leads to the serious shortage of the hooking space of the bottom steel wire hook corresponding to the lower end of the backrest side plate. Due to the limited space, the traditional bottom steel wire hook cannot be hooked, so it is urgent for the technical personnel in the field to solve this problem. SUMMARY

[0003] In view of the problems existing in the prior art, the utility model aims to provide a suspension mounting structure of automobile seat backrest, which can solve the problem that the thickness of the backrest assembly of the automobile seat in the X direction becomes narrower and the bottom steel wire hook cannot be hooked.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a suspension mounting structure of automobile seat backrest, which comprises a backrest suspension, two backrest side plates and a bottom edge metal plate connected between the bottoms of the two backrest side plates. The middle and upper parts of the two sides of the backrest suspension are provided with steel wire hooks, the backrest suspension is hooked between the two backrest side plates through the steel wire hooks on the two sides, the bottom ends of the backrest suspension are provided with steel wire supports at the rear, the bottom edge metal plate is provided with clamping holes corresponding to the positions of the two steel wire supports, and the steel wire supports are clamped and fixed in the corresponding clamping holes through clamps, so that the bottom ends of the backrest suspension are supported and fixed on the bottom edge metal plate.

[0005] In the above-mentioned scheme, the backrest suspension comprises two frame steel wires and a plurality of main body steel wires which are arranged oppositely left and right, the frame steel wires extend vertically, the main body steel wires extend horizontally, each main body steel wire is connected to the two frame steel wires, the steel wire hooks are formed by outward extension and bending of the main body steel wires at the corresponding positions, and the steel wire hooks and the main body steel wires jointly constitute a stable frame structure, so that the overall strength and stability of the backrest suspension are greatly enhanced.

[0006] In the above scheme: the backrest suspension further comprises a bottom edge wire connected between the bottom ends of the two frame wires, and the bottom edge wire is fixed with the frame wires by clamps.

[0007] In the above scheme: the wire support is U-shaped, and the two wire supports are integrally bent from the bottom edge wire; this integrated design eliminates the risk of loosening or breaking due to insecure connection between the wire support and the bottom edge wire, and is simple and convenient to process.

[0008] In the above scheme: the clamps are arranged on the rear end crossbeam of the wire support and are clamped into the clamping holes backward to achieve fixed connection of the wire support and the bottom edge sheet metal, which is simple in structure and convenient to install.

[0009] In the above scheme: the clamps are pipe bundle fixing clamps, which are sleeved on the rear end crossbeam of the wire support, and the pipe bundle fixing clamps are low in cost and convenient to install.

[0010] In the above scheme: the main wires are five in total and are arranged in an up-down interval, wherein the middle portions of the upper three main wires are connected by one vertical rigid wire, and the middle portions of the lower two main wires are connected by another vertical rigid wire; that is, the middle portions of the five main wires are not integrally connected by one vertical rigid wire, and the design of the broken vertical rigid wire is beneficial to avoiding excessive rigidity of the middle portion of the backrest suspension and affecting the comfort of the backrest suspension support.

[0011] The backrest suspension of the utility model has the advantages that: 1. The wire supports extending backward are arranged at both ends of the bottom of the backrest suspension, and are clamped and fixed by using the clamping holes on the bottom edge sheet metal, thereby ingeniously avoiding the problem of insufficient hooking space of the traditional bottom wire hook, and the design enables the backrest suspension installation structure to better adapt to the design trend of the X-directional thickness of the backrest assembly becoming narrower in modern automobiles, realizes reliable installation in limited space, improves the flexibility and space utilization rate of automobile seat design, and helps automobile manufacturers to meet the space demand of consumers in the vehicle while optimizing the seat layout; 2. The wire support and the bottom edge sheet metal are fixed by clamping with the clamps, so that the installer only needs to align the wire support with the clamping holes on the bottom edge sheet metal, and then easily clamp the clamps to complete the bottom fixation, and the clamping holes are arranged on the bottom edge sheet metal, which is convenient and low in cost.
