Problems solved by technology

Consumes a lot of equipment and energy
At the same time, due to the accumulation of multi-component and multi-process manufacturing tolerances, the manufacturing tolerance of the backrest frame assembly will be relatively large
[0004] However, due to the poor energy absorption of plastic materials and the weakness of force hardening, the seat back frame with the same or similar structure as the existing metal seat back frame is directly formed by plastic, which cannot achieve the static strength and impact strength of the seat. Unable to withstand a huge impact

Embodiment Construction

[0029] see Figure 3-12 , the car seat back frame 2 of the present invention replaces the original product composed of a plurality of metal parts with a plastic product of one-time injection molding or pressure injection molding. The processing technology of the original metal frame is greatly optimized, and the shackles of the original metal frame are broken, so that the whole seat has a better appearance effect and the comfort performance of the whole chair under the platform of the plastic seat frame.

[0030] What back frame 2 of the present invention uses is plastic material, and the density of the seat back of plastic material is usually much smaller than metal material, and plastic replaces metal, and the weight of seat back frame is greatly reduced. The material selection of the new product of the present invention is flexible, and any material whose strength and toughness can make the framework meet the requirements of regulations can be selected, such as PA66+GF or P...

Abstract

The invention provides a plastic car seat back skeleton which is made from plastic material through one-step forming and is provided with a shell extending along the circumference, wherein the lateral section of the shell is n-shaped, the inside of the shell with the n-shaped section is provided with honeycomb reinforcing ribs; the position which bears larger stress, of the shell with the n-shaped section has larger thickness; and the honeycomb reinforcing ribs on the whole skeleton can have different height and / or thickness. The car seat back skeleton of the invention is made from plastic instead of metal so that the weight of the car seat back skeleton can be greatly reduced; in addition, the corrosion resistant of the plastic material is better so as to prolong the service life of the product.

Description

technical field [0001] The invention relates to a car seat, in particular to a car seat back frame. Background technique [0002] At present, most of the backrest frames used in passenger car seats on the market are metal backrests. The main disadvantages are: (1). Adapt to the environmental requirements of the car body; (2), the processing procedure is complicated, and there are as many as dozens of procedures in the whole production process, which brings certain difficulties to the processing, manufacturing and management; (3), the overall parts are heavy, and it is difficult to meet the Requirements for lightweight vehicles and national calls for energy conservation and emission reduction; (4) In terms of energy consumption, the production of plastic raw materials can save more energy than the production of metal raw materials. The above deficiencies have promoted new materials and new processes to replace metals design ideas. [0003] Such as figure 1 and figure 2 A...
