Description

Technical Field

[0001] The utility model belongs to the field of springs, and particularly relates to a comfortable seat frame serpentine spring. Background Art

[0002] A serpentine spring refers to a spring with a serpentine shape. It is often used on the seat frame of an automobile to make the automobile seat elastic and increase the comfort of riding. Most of the seat frame serpentine springs on the market are arranged in multiple identical serpentine springs. When riding, the stress on each section of the serpentine spring is basically equal. When a person sits on an automobile seat, the contact surface with the seat is often irregular. After a long time of riding, fatigue and soreness will occur in the uneven places of the contact surface. Summary of the Invention

[0003] The purpose of the utility model is to provide a comfortable seat frame serpentine spring for the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved by the following technical solutions: A comfortable seat frame serpentine spring, including a serpentine spring group, characterized in that the serpentine spring group includes a support spring located outside the serpentine spring group and two symmetrically arranged telescopic springs located inside the serpentine spring group;

[0005] The support spring is bent in a multi-segment "S" shape, and an elastic band one for constriction and having an elastic reset function is arranged between every other bending position. An annular telescopic part is arranged in the middle of the elastic band one;

[0006] Support springs symmetrically arranged with the support spring are arranged on both sides of the telescopic spring, and multiple narrow-mouth springs are arranged inside the telescopic spring.

[0007] In the above-mentioned comfortable seat frame serpentine spring, an elastic band two is arranged between the narrow-mouth spring and the symmetrically arranged narrow-mouth spring, and multiple telescopic parts are arranged on the elastic band two.

[0008] In the above-mentioned comfortable seat frame serpentine spring, installation rods for installation extend horizontally outwards at both ends of the support spring and the telescopic spring, and a fixing plate for fixing and supporting is arranged between the installation rods.

[0009] Compared with the prior art, the comfortable seat frame serpentine spring of the present utility model maintains stability during riding through the support spring, improves the fit between the human body and the automobile seat through the telescopic spring, and greatly increases the comfort during riding. Brief Description of the Drawings

[0010] Figure 1 It is a main body schematic diagram of the comfortable seat frame serpentine spring.

[0011] In the figure, 1 is a support spring; 2 is a telescopic spring; 3 is an elastic band one; 4 is a telescopic part; 5 is a narrow - mouth spring; 6 is an elastic band two; 7 is a mounting rod; 8 is a fixing plate. Detailed implementation mode

[0012] The following are specific embodiments of the present utility model and in combination with the attached drawings, the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0013] As Figure 1 shown, this comfortable seat frame serpentine spring includes a serpentine spring group. The serpentine spring group includes a support spring 1 located outside the serpentine spring group and two symmetrically arranged telescopic springs 2 located inside the serpentine spring group;

[0014] The support spring 1 is bent in a multi - section "S" shape, and an elastic band one 3 for constricting and having an elastic reset function is arranged between every other bending position. An annular telescopic part 4 is arranged in the middle of the elastic band one 3;

[0015] On both sides of the telescopic spring 2, there are support springs 1 symmetrically arranged with the support spring 1, and multiple narrow - mouth springs 5 are arranged inside the telescopic spring 2;

[0016] Between the narrow - mouth springs 5 and the symmetrically arranged narrow - mouth springs 5, there is an elastic band two 6, and multiple telescopic parts 4 are arranged on the elastic band two 6.

[0017] After a person sits on the car seat, the buttocks will contact the position of the telescopic spring 2. Since the number of bending positions of the narrow - mouth springs 5 on the telescopic spring 2 is more than that of the support spring 1, and the bending distance is smaller, the ductility of the narrow - mouth spring 5 is better than that of the support spring 1, and it can better fit the buttocks curve. The number of telescopic parts 4 on the elastic band two 6 is more than that on the elastic band one 3, so the ductility of the elastic band two 6 is greater than that of the elastic band one 3, which can assist in increasing the ductility of the narrow - mouth spring 5.

[0018] Furthermore, both ends of the support spring 1 and the telescopic spring 2 horizontally extend outwards for installation with mounting rods 7, and a fixing plate 8 for fixing and supporting is arranged between the mounting rods 7.

[0019] The specific embodiments described herein are only illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model belongs can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.

[0020] Although terms such as support spring 1, telescopic spring 2, first elastic band 3, telescopic part 4, narrow-mouth spring 5, second elastic band 6, mounting rod 7, and fixing plate 8 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model.
