Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, specifically an automotive seat back frame with foldable side wings. Background Technology

[0002] The car seat backrest frame is the core support structure of the seat back. Its main function is to fix the seat foam, fabric and other external components, and to provide stable support for the passenger's back. Most car seat backrest frames currently in use have difficulty folding the side wings. During use, if the side wings are difficult to fold, they will occupy a lot of space. When transporting the frames one by one, the side wings will press against the front frame, resulting in large gaps between the frames, which wastes transport space and makes transportation inconvenient, thus reducing the practicality of the car seat backrest frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of a folding and fixing mechanism, can achieve the function of folding the side wings. During use, the side wings are folded by rotating the hinge, and the side wings are kept in the folded state by the cooperation of bolts and threaded holes. This avoids the situation where the side wings occupy a large space due to the difficulty of folding them. During transportation, when the frames are arranged one by one, the side wings will press against the frame in front, resulting in a large gap between the frames, which wastes transportation space and makes transportation inconvenient. This ensures the convenience and practicality of the frame during transportation.

[0013] 2. This utility model can reinforce the seat back frame by setting up reinforcement components. During use, the support rod and the reinforcement rod cooperate to form a triangle. The stability of the triangle is used to reinforce the seat back frame, making the back frame more stable and durable. It has higher strength and is more reliable and firm during transportation and subsequent use, thus ensuring the strength performance of the back frame. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1 As shown, the present invention provides the following technical solution, including a skeleton body 1, a folding and fixing mechanism 2 on one side of the skeleton body 1, and a reinforcing component 3 inside the skeleton body 1.

[0018] Specifically: When the car seat back frame is needed, the side wing body 201 must first be fixed to the frame body 1. The side wing body 201 is fixed to the frame body 1 by the folding and fixing mechanism 2. When the frame body 1 needs to be transported later, the side wing body 201 needs to be folded up to make each frame body 1 occupy less transport space. The side wing body 201 is folded up by the folding and fixing mechanism 2 to make each frame body 1 occupy less transport space. After the side wing body 201 is folded and fixed, it can be transported. When the frame body 1 is used later, the frame body 1 is reinforced by the reinforcement component 3 to complete the work.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, a folding and fixing mechanism 2 is provided on one side of the frame body 1. The folding and fixing mechanism 2 includes a side wing body 201. A side wing body 201 is provided on one side of the frame body 1. A hinge 202 is provided on one side of the side wing body 201. One end of the frame body 1 is connected to the inner side of the hinge 202. A fixing bolt 203 is provided inside the hinge 202. A fixing plate 204 is provided on the outer wall of the side wing body 201. Threaded holes 205 are opened in both the interior of the fixing plate 204 and the interior of the frame body 1. A spring 206 is provided on the other side of the side wing body 201. There are two sets of three springs 206. A support plate 207 is provided at one end of each spring 206. There are two side wing bodies 201 and two sets of two hinges 202.

[0020] Specifically: When the car seat back frame is needed, the side wing body 201 needs to be fixed to the frame body 1 first. At this time, the hinge 202 is connected to the side wing body 201 by fixing bolts 203, and the side wing body 201 is fixed in a suitable position on the frame body 1. When the frame body 1 needs to be transported later, the side wing body 201 needs to be folded up so that a single frame body 1 occupies less transport space. At this time, by rotating the hinge 202, the side wing body 201 is rotated and folded to both sides of the frame body 1. At this time, the threaded hole 205 opened in the fixing plate 204 will be aligned with the threaded hole 205 opened on one side of the frame body 1. Then, the bolt is rotated and inserted into the threaded hole 205 to fix the position of the side wing body 201, thereby completing the folding and fixing work.

[0021] like Figure 1 and Figure 4 As shown, a reinforcing component 3 is provided inside the skeleton body 1. The reinforcing component 3 includes a support rod 301. The support rod 301 is circular in shape. There are two reinforcing rods 302 inside the skeleton body 1. The outer wall of the reinforcing rod 302 is connected to the outer wall of the support rod 301.

[0022] Specifically: When the skeleton body 1 is used subsequently, the support rod 301 and the reinforcing rod 302 are set up, and the cooperation between the two makes the two form a stable triangle, which improves the stability of the skeleton body 1, strengthens and reinforces the skeleton body, thereby completing the reinforcement work.

[0023] The working principle of this utility model is as follows: When the car seat back frame is needed, the side wing body 201 needs to be fixed to the frame body 1 first. At this time, the hinge 202 is connected to the side wing body 201 by fixing bolts 203, and the side wing body 201 is fixed in a suitable position on the frame body 1. When the frame body 1 needs to be transported later, the side wing body 201 needs to be folded up so that a single frame body 1 occupies less transport space. At this time, by rotating the hinge 202, the side wing body 201 is rotated and folded to the two sides of the frame body 1. On the side, the threaded hole 205 in the fixing plate 204 will be aligned with the threaded hole 205 on one side of the frame body 1. Then, the bolt is rotated and inserted into the threaded hole 205 to fix the position of the side wing body 201, thus completing the folding and fixing work. After the side wing body 201 is folded and fixed, transportation can begin. When using the frame body 1 in the future, the support rod 301 and the reinforcing rod 302 are set up to form a stable triangle, which improves the stability of the frame body 1 and strengthens the frame body, thus completing the reinforcement work.
