AI Technical Summary
Technical Problem
The existing car seat back frame structure is complex, with many parts and high cost, which makes it difficult to meet the stringent requirements of lightweight and whiplash test.
Method used
The seat back frame design adopts an embedded steel wire plastic clip, including a backrest frame assembly, a backrest spring frame, plastic clips and an embedded steel wire structure. This reduces the number of fixed bracket parts and increases stability and lightweight through the embedded steel wire.
Benefits of technology
This achieves lightweighting of the seat and reduction in cost, while solving the problem of traditional injection-molded parts breaking during whiplash tests and meeting the stringent requirements of whiplash tests.

Abstract
The utility model relates to the technical field of seat backrest frameworks, in particular to a seat backrest framework with an embedded steel wire plastic buckle, which comprises a backrest frame assembly and a backrest spring frame arranged on the inner side of the backrest frame assembly, tail end hooks are symmetrically arranged on two sides and the bottom of the backrest spring frame, and the tail end hooks are connected with the embedded steel wire plastic buckle. A plastic buckle is connected to a backrest side plate of the backrest frame assembly in a clamped mode, hooks at the tail ends of the two sides of the backrest spring frame are hung on the plastic buckle, a hanging hole is formed in a lower cross beam of the backrest frame assembly, and a hook at the tail end of the bottom of the backrest spring frame is hung on the hanging hole. And a fixed interface of the backrest spring frame is reserved, the assembling performance is good, and the aims of light weight and low cost of the seat are achieved. The structure of adding the embedded steel wire to the plastic buckle belongs to the industry pioneer, is novel and simple in structure, and has the advantages of high expansibility and light weight; the problem of fracture of a traditional injection molding piece in a whiplash test is solved, and parts are few.
