Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to an automotive seat back airbag installation structure. Background Technology

[0002] In the field of automotive safety, airbags, as a crucial passive safety device, play a vital role in protecting the lives of passengers in collisions. With the continuous development of the automotive industry and the increasing demands of consumers for vehicle safety performance, the design and installation technology of automotive seat airbags is also constantly innovating and optimizing. In traditional automotive seat airbag designs, there are some pressing issues regarding the placement of airbags in car seats, especially concerning the placement of the distal airbag near the center console and the proximal airbag near the door. The center console, as an important functional component inside the car, has a compact surrounding space, and the distal airbag usually needs to be installed near the center console. In traditional designs, the backrest foam completely covers the distal airbag. However, this design approach has significant drawbacks.

[0003] Because the space between the car's center console and the remote airbag is already limited, completely covering the remote airbag with foam backrests would further compress the installation space of the center console, causing interference between the two. Traditional solutions to this interference problem involve reducing the size of either the center console or the backrest. However, both reducing the size of the center console and the backrest negatively impact passenger comfort. Reducing the size of the center console may affect its functionality and ease of operation, while reducing the backrest size reduces the seat's support and comfort, making passengers feel uncomfortable during the ride. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention aims to provide an airbag installation structure for car seat backrests, which can not only achieve stable installation of remote and proximal airbags, but also avoid interference with the center console, and at the same time not affect the passenger's riding experience.

[0005] To achieve the above objectives, this utility model proposes an airbag installation structure for a car seat backrest, including a distal airbag near the center console and a proximal airbag on the side of the backrest door, as well as a backrest frame, a backrest foam, and a backrest cover. The backrest foam covers the backrest frame, and an L-shaped bracket plate is welded outward on each of the two end plates of the backrest frame. The distal and proximal airbags are respectively fixed to the bracket plates on their corresponding sides, and both the distal and proximal airbags are enclosed within the backrest foam. A window is provided on the end of the backrest foam corresponding to the distal airbag near the center console, through which the corresponding side of the distal airbag is exposed. The backrest cover covers the backrest foam and also covers the exposed portion of the distal airbag.

[0006] In the above scheme: the shape and size of the window are completely consistent with the shape and size of the corresponding side of the distal airbag, and the corresponding side of the distal airbag can just expose the window.

[0007] In the above solution: the corresponding side of the distal airbag is flush with the surface of the backrest foam around the window. From the perspective of the seat appearance, the distal airbag is flush with the surface of the backrest foam, without any obvious bulges or depressions, making the seat surface look flat and smooth, with smooth and natural lines, perfectly integrated with the overall design style of the seat, enhancing the aesthetics and refinement of the seat.

[0008] In the above solution: the support plate includes a horizontal section and a vertical section, and the vertical section is welded to the corresponding side plate of the backrest frame. The structure is simple and easy to process.

[0009] In the above scheme: there are three welding points between the vertical section of the support plate and the corresponding side plate of the backrest frame. The three welding points are distributed in a triangular shape, which helps to ensure the installation stability of the support plate.

[0010] In the above scheme, both the distal airbag and the proximal airbag are fixed to the top surface of the horizontal section of the corresponding side support plate by two screws arranged at intervals, so that the airbag can be smoothly deployed from the front side of the support plate in the event of an accident.

[0011] The beneficial effects of this utility model are as follows: 1. In traditional designs, the backrest foam completely covers the distal airbag. Due to the limited space between the car's center console and the distal airbag, interference between the two is very likely, affecting the normal installation of the center console. However, this utility model reduces the space occupied by the backrest foam in the center console installation while ensuring the normal installation and function of the distal airbag. This effectively avoids the interference problem between the distal airbag and the center console, without reducing the size of the center console or backrest. It ensures the integrity of the center console's function and maintains the comfort of the seat. 2. The window is located on the side of the backrest foam, which does not reduce the backrest's support and wrapping effect on the passenger's body, or has a negligible impact. 3. Both the distal and proximal airbags are fixed to the backrest frame with bracket plates, resulting in a simple structure and convenient installation. Attached Figure Description

[0016] like Figure 1 As shown in Figure 4, an airbag installation structure for a car seat backrest mainly consists of a distal airbag 1 near the center console and a proximal airbag 2 on the side of the backrest door, as well as a backrest frame 3, a backrest foam 4, and a backrest cover 7.

[0017] The backrest foam 4 covers the backrest frame 3. An L-shaped support plate 5 is welded outwards to each end of the backrest frame 3. The distal airbag 1 and proximal airbag 2 are respectively fixed to the corresponding support plates 5, and both are enclosed within the backrest foam 4. A window 6 is provided at the end of the backrest foam 4 corresponding to the distal airbag 1 near the center console. The corresponding side of the distal airbag 1 is exposed through this window 6. The backrest cover 7 covers the backrest foam 4 and also covers the exposed portion of the distal airbag 1.

[0018] Ideally, the shape and size of window 6 should be exactly the same as the shape and size of the corresponding side of the distal airbag 1, so that the corresponding side of the distal airbag 1 can just expose window 6.

[0019] Ideally, the corresponding side of the distal airbag 1 should be flush with the surface of the backrest foam 4 around the window 6. From the perspective of the seat appearance, the distal airbag 1 and the backrest foam 4 should be flush, without any obvious bulges or depressions, making the seat surface look flat and smooth with smooth and natural lines, perfectly blending with the overall design style of the seat, enhancing the aesthetics and refinement of the seat.

[0020] Specifically, to avoid the seat surface at the corresponding position of the remote airbag 1 appearing uneven or having bumps, a molded plate can be sewn on the inner wall of the backrest cover 7 at the corresponding position. The molded plate is relatively thin, generally 1 to 2 mm thick.

[0021] Ideally, the support plate 5 includes a horizontal section and a vertical section, with the vertical section welded to the corresponding side plate of the backrest frame 3, resulting in a simple structure and convenient processing.

[0022] Ideally, there should be three welding points between the vertical section of the support plate 5 and the corresponding side plate of the backrest frame 3, with the three welding points arranged in a triangular pattern, which helps to ensure the installation stability of the support plate 5.

[0023] Ideally, both the distal airbag 1 and the proximal airbag 2 are fixed to the top surface of the horizontal section of the corresponding side support plate 5 by two screws arranged at intervals, so that the airbags can be smoothly deployed from the front side of the support plate 5 in the event of an accident.
