Seat headrest framework

Abstract

The invention provides a seat headrest framework, which comprises a headrest framework reinforcing plate and a U-shaped support pipe, wherein the U-shaped support pipe is fixed in the middle of the back of the headrest framework reinforcing plate and is used for supporting a backrest; the seat headrest framework also comprises a headrest pipe and a headrest framework reinforcing rod; two vertical C-shaped grooves are punched at both ends of the headrest framework reinforcing plate; the headrest pipe is in an n shape, and both edges of the headrest pipe are embedded into the C-shaped grooves and are fixed by welding; and the headrest reinforcing rod passes through a punching hole in the middle of the headrest framework reinforcing plate, extends out of the back of the headrest framework reinforcing plate and is in welded connection with the reinforcing plate. The headrest framework is welded with a meshed framework to install the framework for the integral backrest; and the reinforcing rod on the headrest framework provides the support of headrests so as to prevent the headrests of passengers from moving backward due to inertia in the process of forward collision and can prevent the headrests from displacing excessively and overturning while protecting heads of the passengers.

Description

technical field [0001] The invention belongs to the technical field of automobile bodies, and in particular relates to a skeleton structure of a seat headrest. Background technique [0002] In the development of automobiles, the seat is one of the main safety performance parts, and its strength has high design requirements. As a head protection device, the headrest plays a very important role in protecting the occupant's head in a collision. The general rear seat fixed headrest has a simple structure, such as Figure 4 As shown, it is made up of a connecting plate 41 welded with the backrest and a hanging steel wire 42, and the hanging steel wire 42 is welded on the connecting plate 41 back side. The strength of the headrest with this fixed structure meets the requirement in GB15083-2006 that "the headrest and its fixing device should ensure that the maximum backward movement X of the head shape should be less than 102mm when measured according to the specified static test ...

AI Technical Summary

Problems solved by technology

The strength of the headrest with this fixed structure meets the requirement in GB15083-2006 that "the headrest and its fixing device should ensure that the maximum backward movement X of the head shape should be less than 102mm when measured according to the specified static test method", and it cannot reach Require

However, if the rear seats are equipped with movable headrests, the strength can be greatly improved and the requirements of the regulations can be met, but the cost will increase accordingly
