Some car seats are in the state of a single recliner, that is, there is only one recliner , installed on one side of the backrest frame, such a setting makes the force on the backrest frames on both sides uneven, which may easily lead to insufficient strength of the backrest frame. In addition, due to the difference in the installation structures on both sides, it is difficult to match the seat frame during assembly.

Utility model content

In order to solve the above technical problems, the utility model provides a single recliner car seat back frame with reliable strength and convenient assembly.

Its technical scheme is as follows:

A car seat back frame with a single recliner, including a main support tube. The end portion passes through the closed portion and extends vertically downward to form a seat frame connecting portion. The main support tube adopts an integral structure, which effectively ensures the strength of the backrest frame. Since only one recliner is provided, the structure of the backrest frame of the car seat is simplified, and the total amount of the backrest frame is reduced, which is beneficial to the weight reduction of the whole vehicle and saves material, the connecting plate on the recliner is provided to facilitate the installation of the recliner, and the seat frame connection part passing through the closed part can be conveniently connected and fixed with the seat frame.

In order to further facilitate the connection and fixation with the seat frame, the connection part of the seat frame has a flat structure, and a mounting hole is provided in the middle.

Further, lateral supports are respectively provided on both sides of the main support tube, the two ends of the lateral supports are fixed to the main support tube, and the middle part protrudes outward. This structure can form a good support for the foam material on the side of the seat, ensure the lateral support strength of the backrest frame, and improve comfort.

Further, the closed part of the main support tube is distributed with a back support to support the foam material of the main part of the backrest.

Further, two headrest installation pipes are arranged symmetrically on the upper part of the main support pipe, which facilitates the installation of the headrest.

Further, the main support tube is surrounded by an upper tube part, a lower tube part and side tube parts on both sides, and one end of the lower tube part is flat and is welded and fixed on one side tube part. By adopting the above structure, the welding area between the lower pipe part and the side pipe part can be increased to ensure the connection strength thereof.

Beneficial effect:

The car seat back frame of the single recliner adopting the above technical scheme has the advantages of simple and novel structure, reliable strength, convenient installation, good comfort and light weight.

Detailed ways

Below in conjunction with embodiment and accompanying drawing, the utility model is further described.

A kind of car seat back frame of monoadjuster recliner as shown in Fig. 1 and Fig. 2, comprises main support tube 1, and described main support tube 1 is an integral closed tube, comprises upper tube part 1a, lower tube part 1b and the side tube parts 1c on both sides are combined to form a "mouth"-shaped closed structure, wherein the lower tube part 1b is formed by bending the lower end of the right side tube part 1c inwardly, and is connected with the left side tube part 1c Welding and fixing, two headrest installation pipes 5 are symmetrically arranged on the upper pipe part 1a, the headrest installation pipes 5 are vertically arranged, the corresponding position of the upper pipe part 1a is flattened, and the right side pipe part 1c is welded and fixed There is an upper connecting plate 2 of the recliner, and the lower end of the side pipe part 1c on the other side passes through the closed part and extends vertically downward to form a seat frame connecting part 11 .

The seat frame connecting portion 11 is flattened into a flat structure, and a mounting hole 11a is provided in the middle. The mounting hole 11a is opposite to the upper connecting plate 2 of the recliner, and is used for connecting with the seat frame (not shown in the figure).

The side tube parts 1c on both sides of the main support tube 1 are provided with lateral supports 3 respectively, and the side supports 3 are strip-shaped and vertically arranged, and the two ends are fixed with the side tube parts 1c on the same side, The middle protrudes outwards.

It can be seen from FIG. 1 that six back supports 4 are distributed in the closed part of the main support tube 1, two of which are arranged in parallel near the upper tube part 1a, and the four back supports 4 below form a "mouth". ”-shaped support structure, the two ends of the back support 4 are bent, and are fixed on the side pipe parts 1c on both sides by welding or jacking.

It can be seen from FIG. 3 that the left end of the lower tube part 1b is flat, that is, when the main support tube 1 is bent, the end is flattened to increase the size of the lower tube part 1b and the side tube. Part of the welding area to ensure its connection strength.

Finally, it should be noted that the above description is only a preferred embodiment of the utility model, and under the inspiration of the utility model, those skilled in the art can make many A similar representation, such transformations all fall within the protection scope of the present utility model.
