Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "sleeved/connected," "connected," and the like are to be construed broadly, e.g., "connected," which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1-3, the invention provides a device for adjusting the strength of a backrest frame of an automobile seat, which comprises a reinforcing plate 2 with a lug 21 at the rear end, wherein the upper end of the reinforcing plate 2 is fixedly connected with the lower end of a side reinforcing rib of a backrest boundary beam 1, the lug 21 is fixedly connected with the rear end surface of the backrest boundary beam 21, and a cavity 201 is formed between the reinforcing plate 2 and the backrest boundary beam 1.

In the structure of the invention, the reinforcing plate 2 is added on the backrest boundary beam 1 to ensure that the reinforcing plate 2 and the backrest boundary beam 1 can form a cavity, and the shape and the size of the reinforcing plate 2 are selected according to actual requirements.

As shown in fig. 4 to 7, the principle of the structure provided by the present invention is that the strength of the back frame of the car seat is controlled by the size of the formed cavity 201, the volume increase strength of the cavity 201 along the extending direction of the back frame edge 1 is increased, the volume decrease strength of the cavity 201 along the extending direction of the back frame edge 1 is reduced, the cavity can be selected according to actual needs, the shape of the reinforcing plate only needs to be changed to increase or reduce the strength of the back frame, and the back frame edge beam with higher development cost does not need to be modified so as to meet the requirements of different cars for the strength of the seat.

The extending direction of the backrest side frame 1 indicates the installation direction of the backrest side frame 1, for example: the extending direction of the backrest side frame 1 arranged vertically indicates the vertical direction, and the extending direction of the backrest side frame 1 arranged horizontally indicates the horizontal direction.
