Embodiment 1

[0089] Embodiment 1: the first kind of car seat frame, see Figure 1-Figure 4 , an n-shaped frame 1 integrally formed by plastic material, its cross-section is "U"-shaped (or "V"-shaped, or "H"-shaped, or "king"-shaped, or trapezoidal) structure, in n The inner side of the shaped frame 1 is provided with a reinforcing rib 7, which is a continuous cross-shaped reinforcing rib 7, or a wave-shaped reinforcing rib 7, or a grid-shaped or convex nail-shaped reinforcing rib 7. The thickness of the U-shape is 4-8mm, and the thickness of the ribs inside the U-shape is 3-5mm, which meets the requirements of the mechanical test of the seat frame. The width of the n-shaped frame 1 is 20-40mm, and the groove width of its cross section is 15-35mm.

[0090] A backboard 2 is connected to the inside of the two sides of the n-shaped frame 1 from the middle to the bottom, and the backboard 2 is made of braided fiber + PP. Backrest board 2 is arc-shaped board. Its upper width is greater than t...

Embodiment 2

[0095] Embodiment 2: the second kind of automobile seat frame, see Figure 1-Figure 4 , the content is basically the same as that of Example 1, except that the backboard 2 adopts transverse continuous fiber yarn + PP prepreg.

Embodiment 3

[0096] Embodiment 3: the third kind of automobile seat frame, see Figure 5 , Figure 6 and Figure 7 , the content is basically the same as in Embodiment 1, the difference is that the backboard and the n-shaped frame are assembled, and flanges 12 are set on both sides of the backboard, see Figure 7 , The width of the flange 12 adapts to the width of the n-shaped frame. After the flanges 12 on both sides of the backboard 2 are set on the inner sides of the two frames of the n-shaped frame 1, they are fixed by bolts 11, see Figure 5 .

Abstract

The invention discloses a manufacturing method of a seat framework. The seat framework comprises an n-shaped frame which is integrally formed by a thermoplastic composite material, wherein reinforcing ribs are arranged on the inner side of the n-shaped frame; a backrest plate is connected to the inner sides, from the middles to the bottoms, of two side frames of the n-shaped frame, and is made of a woven fiber and PP (Polypropylene) pre-impregnated sheet or a horizontal continuous fiber yarn and PP pre-impregnated sheet. The structure of the seat backrest framework is improved and optimized, force bearing points can be uniformly dispersed, the force bearing time can be prolonged, and the maximum impact strength is greatly reduced. The overall force bearing situation is obviously improved. A finite element analysis result accords with an interurban coach safety standard. The thickness of the backrest plate is decreased, materials are saved, the cost is reduced, the seat framework is safe, reliable and long in service life, and the comfort of a human body is improved.

Description

technical field [0001] The invention relates to the technical field of seats, in particular to a seat of vehicles such as automobiles, trains and airplanes and a backrest frame of an office chair. The backrest frame is the seat frame. Background technique [0002] Most of the traditional car seats are composed of metal skeleton and outsourcing. The metal backrest skeleton has problems such as difficult processing and complicated process. The electroplating process in anti-corrosion treatment will pollute the environment; moreover, it is heavy and expensive to manufacture, so it needs to be upgraded. Ordinary plastic seats or ordinary plastic skeleton seats have poor strength, are easily damaged, and have potential safety hazards, so they are not suitable for use as seats for high-speed cars, trains, airplanes and other transportation vehicles. [0003] The impact force carried by the car seat frame is mainly affected by factors such as body weight and vehicle speed. For bus...
