Background
The functions of the car seat are more and more abundant, and thus the structural design thereof tends to be complicated. In order to improve the comfort of the seat, a plurality of joints between each part of the seat frame are designed to be adjustable so as to adjust the posture of the seat, thereby sufficiently and appropriately supporting each part of the body, reducing the joint tension and enabling the body to be in a highly relaxed state. Under the concept of 'zero gravity', the adjustment range of each part of the seat is large, but the adjustment has a mutually contradictory relation with the stability and the safety. To meet the seat safety requirements, careful design and testing must be performed during the seat frame development phase, which also presents some challenges in the design of the seat attachment structure. For example, the belt retractor of a "zero gravity" seat must be mounted on the seat body, and cannot be mounted on the vehicle body as a conventional seat, due to the large adjustment range. On the one hand, the large adjustment range of the seat itself poses a challenge to the strength of the seat frame, and on the other hand, the design of the seat belt retractor mounted on the seat further increases the challenge to the structural strength faced by the seat frame. Therefore, it is necessary to improve the design of the seat frame reasonably and to enhance the strength of the frame, particularly the strength of the back frame.

A first reinforcing metal plate 140 is connected between the side tube 120 and the front flange 133 of the side plate, and the three are enclosed to form a hollow box-shaped structure.
As shown in fig. 1, the first reinforcing sheet metal 140 includes a first reinforcing plate 141, the first reinforcing plate 141 is disposed parallel to the edge plate body 131, and a rear edge of the first reinforcing plate 141 is provided with a first rear flange 142, and the first rear flange 142 abuts against and is welded to the edge tube 120. The front edge of the first reinforcing plate 141 is provided with a first forward flange 143 facing the sideboard body 131, the first forward flange 143 is adapted to the shape of the sideboard forward flange 133, and the first forward flange 143 abuts against and is welded to the sideboard forward flange 133.
The front edge of the sideboard body 131 extends forward gradually from the upper end to the middle part of the sideboard body 131 so that the upper end to the middle part of the sideboard body 131 widens gradually. The upper portion of the side panel rear flange 132, the upper portion of the side panel front flange 133 and the upper portion of the side panel body 131 are wrapped around and abut against the side tube 120 and are welded to each other, thereby improving the strength and stability of the connection. The purpose of widening the middle and lower portions of the sideboard body 131 is to facilitate the installation of seat foam and trim covers, as well as ancillary structural members, while increasing strength and providing a higher connection strength with the seat recliner.
In this embodiment, the side panel rear flange 132 and the side panel front flange 133 are located on the inner side of the side panel body 131, and the side tube 120 and the first reinforcing metal plate 140 are also located on the inner side of the side panel body 131. As shown in fig. 1 and 2, in order to further improve the strength, a second reinforcing sheet metal 150 is disposed on the outer side of the sideboard body 131, the second reinforcing sheet metal 150 is attached to the outer side of the sideboard body 131 and the rear side of the sideboard back-turned edge 132, and the second reinforcing sheet metal 150 is welded to the sideboard body 131.
As shown in fig. 1, the second reinforcing sheet metal 150 includes a second reinforcing plate 151, the second reinforcing plate 151 abuts against the sideboard back-flanged edge 132, the edge of the second reinforcing plate 151 close to the sideboard body 131 is connected with a second flanged edge 152 facing forward, the second flanged edge 152 abuts against and is welded with the sideboard body 131, and the lower part of the second flanged edge 152 is in accordance with the shape of the lower part of the sideboard body 131.
A bar-shaped reinforcing rib protruding backward is further formed on the second reinforcing plate 151, and the reinforcing rib extends in the vertical direction to further improve the strength thereof.
The reinforced back side panel of the present embodiment is used for a seat back frame as follows.

The reason why the unilateral back side plate of the seat back framework is designed in a reinforcing way is that the safety belt retractor is installed on the seat framework and stretches out from the seat back side close to the reinforced back side plate, and when the safety belt is locked to ensure the safety of a passenger in an emergency, the lateral back side plate bears larger acting force, so that the strength of the lateral back side plate must be improved, and the requirement of the safety of the seat is met. The backrest side plate on the other side is relatively low in stress, so that a reinforcing design is not performed. The left and right side plate metal plates 130 of the seat back frame are in mirror symmetry, so that the production is convenient, and only the first reinforcing metal plate 140 and the second reinforcing metal plate 150 are added to reinforce the side plate of the seat back frame. During assembly, the side tube 120 and the two side plate panels 130 are assembled first, and then the first reinforcing panel 140 and the second reinforcing panel 150 are welded to the side of the backrest side plate to be reinforced.
Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and the scope of the present invention.
