Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a foam anti-cavitation structure for the B-side of a seat back. Background Technology

[0002] As people's demands for automotive comfort increase, mechanical massage functions in car seats can effectively improve seating comfort, especially in high-end models. The core of this system is the combination of mechanical structure, control system, and ergonomic design to provide users with enhanced comfort, health support, and a better driving experience. However, during prolonged use, it has been found that mechanical seat back massage systems often cause the backrest foam to bulge and collapse during operation. Utility Model Content

[0003] In view of the above problems, the purpose of this utility model is to provide a foam B-side anti-hollow structure for seat backrests to prevent the foam backrest from hollowing and collapsing during mechanical massage, so as to overcome the shortcomings of the prior art.

[0004] This utility model provides a seat back foam B-side anti-cavitation structure, including a seat frame, seat foam foamed on the seat frame, and a seat back massage system disposed at the seat back position of the seat frame. The improvement is that an auxiliary limiting plate is pre-embedded in the seat foam located at the seat back position. The auxiliary limiting plate is located in the seat back foam near the seat back massage system position. The auxiliary limiting plate is fixed to the seat frame by connecting nails. After being fixed to the seat frame, the auxiliary limiting plate is used to improve the support strength of the seat back foam at the seat back massage system position.

[0005] As a preferred embodiment of this utility model, the auxiliary limiting plate is integrally molded with the seat back foam, that is, the auxiliary limiting plate is installed in the foaming mold and foamed together with the foam body.

[0006] As a preferred embodiment of this utility model, the auxiliary limiting plate is provided with a plurality of connecting holes, and the connecting nails are Christmas tree nails. The Christmas tree nails are installed in the connecting holes of the auxiliary limiting plate, and a snap-fit ​​hole is provided on the seat frame corresponding to the position of the connecting hole on the auxiliary limiting plate. The auxiliary limiting plate is fixedly connected to the seat frame through the snap-fit ​​hole of the Christmas tree nail.

[0007] As a preferred embodiment of this invention, the auxiliary limiting plate is a plastic plate.

[0008] The beneficial effects of this utility model are as follows: By pre-embedding an auxiliary limiting plate inside the seat back foam, the seat back foam is fixed to the seat back frame through the auxiliary limiting plate, so that the seat back foam is effectively supported, improving the overall quality and performance of the seat back foam near the seat back massage system, and preventing the seat back foam from becoming hollow and collapsing during the movement of the seat back massage system. Attached Figure Description

[0009] Other objects and results of this invention will become more apparent and readily understood with reference to the following description taken in conjunction with the accompanying drawings, and with a more complete understanding of the invention. In the drawings:

[0010] Figure 1 This is a schematic diagram illustrating the location of hollow spots in the backrest of a seat in existing technology.

[0011] Figure 2 This is a partial cross-sectional view of the connection between the seat back foam and the seat frame in this embodiment.

[0012] The attached reference numerals include: seat back foam 1, Christmas tree nail 2, and seat frame 3. Detailed Implementation

[0013] See Figure 2 As shown, this embodiment provides a seat back foam B-side anti-cavitation structure, including a seat frame, seat foam foamed on the seat frame, and a seat back massage system disposed at the seat back position of the seat frame. An auxiliary limiting plate (not shown) is pre-embedded in the seat foam located at the seat back position. The auxiliary limiting plate is located at the cavitation position A of the seat foam. The auxiliary limiting plate is located in the seat back foam 1 near the seat back massage system position. The auxiliary limiting plate is fixed to the seat frame 3 by Christmas tree nails 2. After the auxiliary limiting plate is fixed to the seat frame 3, it is used to improve the support strength of the seat back foam 1 at the seat back massage system position. The auxiliary limiting plate is integrally formed with the seat back foam 1, that is, the auxiliary limiting plate is installed in the foaming mold and foamed together with the foam body. The auxiliary limiting plate is a plastic plate with several connecting holes. Christmas tree nails 2 are installed in the connecting holes of the auxiliary limiting plate. Corresponding to the position of the connecting holes on the auxiliary limiting plate, snap-fit ​​holes are opened on the seat frame 3. The auxiliary limiting plate is fixedly connected to the seat frame 3 through the snap-fit ​​holes of the Christmas tree nails 2.

[0014] Working principle: The seat back foam 1 and the auxiliary limiting plate are foamed and molded as one piece. The foam and the seat back foam 1 are tightly combined. Connection holes are processed at the fixed positions of the seat back foam 1 and the seat frame 3. The seat back foam 1 and the seat frame 3 are connected by Christmas tree nails 2, so that the overall quality and performance of the seat back foam 1 located at the seat back massage system are improved.

[0015] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
