Description

Technical Field

[0001] This utility model relates to the field of automotive component technology, specifically to the fixed connection structure of airbags. Background Technology

[0002] The current automotive market features a wide variety of seat designs, and existing seats are beginning to use large back panels as the back decoration. The structure of the large back panel is that the back panel extends upward to the area above the shoulders, replacing the traditional foam area above the shoulders. This effectively optimizes the shortcomings of the monotonous design of the seat back and can instantly improve the overall design and quality of the car interior. In the event of emergency braking, it can provide better protection for the body of rear passengers and reduce the risk of passenger injury.

[0003] However, most car models typically use a combination of foam and a back panel, with the back panel usually located below the shoulders. From an aesthetic perspective, gaps may appear at the joint, affecting the overall appearance of the seat. Furthermore, over time, the joint may deform, and its sealing is not as good as a single, large back panel. The combination of foam and a single, large back panel also offers less protection for the airbags compared to a single, large back panel.

[0004] In addition, traditional car seat airbags only have foam or plastic back panels outside, without any other metal parts for protection. In emergency situations such as vehicle collisions, they cannot effectively prevent the airbag from being punctured by sharp or hard objects, which may affect the normal deployment of the airbag and thus fail to effectively cushion and protect passengers.

[0005] Currently, there is a lack of an airbag fixing connection structure that can simultaneously provide metal protection for both the airbag and the backplate. Utility Model Content

[0006] In view of the problems existing in the prior art, this utility model provides a car seat airbag and back panel fixed connection structure and a car seat back to solve at least one of the above technical problems.

[0007] To achieve the above objectives, this utility model provides a fixed connection structure for an automobile seat airbag and a back panel, including a backrest frame and a back panel, characterized in that it further includes an airbag mounting assembly installed on at least one side of the left and right sides of the backrest frame.

[0008] The airbag mounting assembly includes an airbag body and a metal protective bracket. The airbag body is provided with a mounting hook and an airbag mounting part. The backrest frame is provided with a hook hole for connecting the mounting hook. The airbag mounting part is in close contact with the backrest frame, and the airbag body and the backrest frame are connected by an airbag fixing bolt passing through the airbag mounting part and the backrest frame.

[0009] The metal protective bracket is fitted on the outer side of the airbag body. The metal protective bracket is connected to the backrest frame, thereby forming a protective cavity that partially covers the airbag body, and the front end of the protective cavity is open.

[0010] The back panel is fixed with clips for engaging the backrest frame.

[0011] This utility model provides convenient protection for the airbag body and backplate by adding a metal protective bracket.

[0012] More preferably, the metal protective bracket includes a first bent portion and a second bent portion in an L-shape, the second bent portion being used to closely fit the rear side of the backrest frame, the top of the first bent portion extending upward in an arc and extending beyond the top of the second bent portion, the area where the first bent portion extends beyond the second bent portion is a top mounting portion, the top mounting portion being used to closely fit the top of the backrest frame;

[0013] The first bending part is connected to a bending member with an L-shaped bend, and the bending member serves as the bottom mounting part, which is used to fit tightly against the side bottom of the backrest frame.

[0014] More preferably, the first bend and the second bend are provided with a reinforcing concave structure.

[0015] More preferably, the metal protective bracket includes a top mounting portion for contacting the top of the backrest frame, a back mounting portion for contacting the rear side of the backrest frame, and a bottom mounting portion for contacting the bottom side of the backrest frame.

[0016] The top mounting part is connected to the backrest frame by fixing bolts and rivet nuts;

[0017] Both the back mounting part and the bottom mounting part are riveted to the backrest frame by rivets.

[0018] More preferably, the rivet nut is riveted and fixed to the top of the backrest frame.

[0019] More preferably, the rivet nut is in close contact with the lower surface of the top mounting portion, and the head of the fixing bolt is in close contact with the upper surface of the top mounting portion.

[0020] More preferably, the bottom front side of the back panel is fixed with a locking foot for engaging the backrest frame.

[0021] More preferably, the back panel includes a head support area for head support and a back support area for back support, wherein the head support area and the back support area are fixedly connected.

[0022] More preferably, the backrest frame is a frame structure.

[0023] A car seat backrest, including a backrest base, characterized in that the backrest base includes the aforementioned car seat airbag and back panel fixed connection structure;

[0024] It also includes a foam layer that covers the front side of the backrest frame and the metal protective bracket.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] This invention protects the airbag by adding a metal protective bracket to the outside of the airbag. In the event of a collision or other emergency, it can effectively prevent the airbag from being punctured by sharp or hard objects, thus ensuring the normal deployment of the airbag and providing effective cushioning protection for passengers.

[0027] Meanwhile, the metal protective bracket can fix the position of the airbag, reducing airbag displacement caused by shaking or long-term use, thus ensuring that the airbag can accurately deploy at the predetermined position at critical moments. Attached Figure Description
