Problems solved by technology

[0009] The technical problem to be solved by the present invention is to provide an automobile seat back frame with a relatively thin thickness in the transverse section of the shell in order to solve the problem that the thickness of the transverse section of the outer shell is relatively thick in the existing plastic seat back frame

Embodiment 1

[0043] see Figure 4 to Figure 8 , the car seat back frame shown in the figure is integrally molded by plastic material. The frame has a shell 100 extending along its circumference. The shell 100 is changed from two aspects to ensure the bending strength and impact strength of the backrest. , the first aspect is to extend the cross section of the two sides 110a, 110b of the shell 100 upward in the Y direction and toward the inner side of the backrest, so that the original "n" is transformed into In this way, the width Dy in the Y direction of the cross-section of the side parts 110a and 110b can be increased, and the thickness Dx in the Y direction of the cross-section of the side parts 110a and 110b can be reduced, so that the thickness of the backrest frame of the car seat can be reduced by 10 mm to 25 mm. Thereby reducing the thickness of the seat back and increasing the usable space in the car. At the same time, the curved surface of the skeleton surface that the occupan...

Embodiment 2

[0071] see Figure 9 to Figure 12 , the car seat back frame given in the figure is different from Embodiment 1 in that the cross-sections of the two sides 110a, 110b of the shell 100 are changed from the original "n" to The rest are the same

[0072] Example 1.

[0073] see Figure 13 and Figure 14 When the reinforcing components 200a and 200b in the above two embodiments are made of regularly woven fiber-reinforced composite materials, the direction of fiber extension forms an angle α with the direction of the trunk line 300 of the backrest, and the angle ranges from 15 degrees to 45 degrees. Due to the low elongation of the fiber, it cannot deform enough to absorb the impact energy during a collision. By setting the fiber angle, when stretched, the fiber reinforced plate can produce a certain deformation through the deviation of the fiber weaving angle, thereby absorbing part of the impact energy. Since the absorbed energy and the backrest deflection angle should be c...

Abstract

The invention provides a backrest skeleton of a car. The backrest skeleton is integrally molded by plastic materials. The skeleton is provided with a shell, a middle cross beam and a bottom cross beam, wherein the shell extends along the circumferential direction of the skeleton; the middle cross beam is used for connecting the middle parts of the two sides of the shell; the bottom cross beam is used for connecting the bottom parts of the two sides of the shell; reinforcing parts are arranged on the inner sides between the upper parts and the bottom parts of the two sides of the shell; and the cross sections of the two sides of the shell are shaped like a horizontal F or a figure shown in the description. The plastic backrest skeleton provided by the invention is not only lighter than a metal skeleton in weight, but also superior to the metal skeleton in space; the section width of the backrest skeleton is thinner than that of the original plastic skeleton by 1.0mm to 2.5mm, so that the thickness of the backrest is reduced, and thus the usable space in the car is enlarged; and simultaneously, the curved surface, which can be possibly contacted by a passenger, on the surface of the skeleton is changed, so that the shape of the backrest skeleton is more closer to the curved surface of the back of a human body, and the area of the supporting surface of the human body is enlarged, therefore, the comfort of the human body is improved, and simultaneously, the thickness of a foaming layer can be reduced by 5mm to 20mm.

Description

technical field [0001] The invention relates to the technical field of automobile seats, in particular to an automobile seat backrest frame. Background technique [0002] Chinese patent publication number CN 101708699A discloses such as figure 1 As shown in the seat back frame, the material of the back frame is plastic, the frame is integrally formed by plastic material and the frame has a shell 1 extending along its circumference, a middle beam 7 connecting the middle of the shell 1 and a bottom connecting the bottom of the shell 1 The transverse beam 9, the transverse section of the outer shell 1 is "n" shape, and the inner side of the outer shell of the n-shaped cross section has honeycomb ribs 2 . The honeycomb ribs 2 may have different heights and / or different thicknesses along the entire framework. The thickness and / or width of the honeycomb reinforcing rib 2 is relatively large at the position where the skeleton is stressed; the thickness and / or width of the honeyco...
