AI Technical Summary
Due to limited space at the airbag position on the back of the seat, it is impossible to effectively block the sharp corners of the metal parts, which increases the risk of occupants' injury.
A sharp-angle foam protection structure at the seat airbag position is adopted, including the seat foam and hot-pressed felt at the airbag position. The hot-pressed felt is fixed on the foam by integrated foam forming, located on the side of the airbag position close to the metal frame, the felt surface density is 600±30g/m2 and the thickness is 2±0.2mm.
Effectively protecting the occupants from being damaged by sharp corners of metal parts such as skeletons and airbags, solving the problem of insufficient space in the existing technology that cannot be blocked by sharp corners. At the same time, the structure is simple and reliable, and the position selection is flexible, which does not affect the layout and installation of other parts.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle seats, in particular to a sharp-corner foam protection structure at the position of a seat airbag. Background Art
[0002] According to the requirements of seat safety regulation GB15083 - 4.1.4, there shall be no protrusions or sharp edges on the surface of the back components of the seat that may increase the injury to the occupants, that is, the radius of curvature of the seat back shall not be less than 3.2 mm; currently, the outer surface of the seat can be blocked by plastic parts, but due to limited space at the edge of the skeleton at the position of the airbag skeleton, there is no fixed position for the plastic parts and the installation space for the plastic parts is insufficient, resulting in the inability to add plastic part blocking. Summary of the Utility Model
[0003] In view of the above problems, the purpose of the utility model is to provide a sharp-corner foam protection structure at the position of a seat airbag, which is used to protect the occupants from being injured by the sharp corners of metal parts such as the skeleton and the airbag, so as to overcome the above-mentioned deficiencies of the prior art.
[0004] To achieve the above purpose, the utility model adopts the following technical scheme:
[0005] A sharp-corner foam protection structure at the position of a seat airbag includes: seat foam at the airbag position and hot-pressed felt located at the airbag position. The hot-pressed felt is fixed on the seat foam at the airbag position through integral foaming molding. The hot-pressed felt is located on the side of the seat foam at the airbag position close to the metal skeleton. The felt surface density of the hot-pressed felt is 600 ± 30 g / m2, and the thickness is 2 ± 0.2 mm.
[0006] Preferably, the hot-pressed felt is fixed to the position of the seat foam at the airbag position on the foam mold through magnetic points or positioning pins. The foam mold is filled with foam material, and the hot-pressed felt and the seat foam at the airbag position are integrally foamed and formed.
[0007] The advantages and positive effects of the utility model are as follows:
[0008] 1. The structure of the utility model is simple and reliable, the position selection is flexible, the operability is strong, the process is simple, and it can effectively solve the problem of difficult flanging process for metal parts.
[0009] 2. The thickness of the hot-pressed felt of the utility model is only 2 mm, so it does not affect the layout and installation of other components, and the protection range can be adjusted arbitrarily. Description of the Drawings

[0012] Reference numerals: Airbag position 1, Airbag position seat foam 2, Hot-pressed felt 3, Metal skeleton 4 Detailed implementation manner
[0013] Refer to Figure 1-2 , this embodiment provides a sharp-corner foam protection structure at the airbag position of a seat, including: an airbag position seat foam 2 and a hot-pressed felt 3 located at the airbag position 1. The hot-pressed felt 3 is fixed on the airbag position seat foam 2 by integral foaming molding. The hot-pressed felt 3 is located on the side of the airbag position seat foam 1 close to the metal skeleton 4. The felt surface density of the hot-pressed felt 3 is 600 ± 30 g / m2, and the thickness is 2 ± 0.2 mm. The hot-pressed felt 3 is fixed to the position of the airbag position seat foam 2 on the foam mold through magnetic points or positioning pins. The foam mold is filled with foam material, and the hot-pressed felt 3 and the airbag position seat foam 2 are integrally foamed and molded.
[0014] Working principle: The hot-pressed felt 3 is integrally formed on the B surface (the side close to the airbag) of the airbag position seat foam 2. After the cooperation of the hot-pressed felt 3 and the airbag position seat foam 2, it can protect the occupant from being injured by the sharp corners of metal parts such as the skeleton and the airbag. Moreover, the felt surface density of the hot-pressed felt 3 is 600 ± 30 g / m2, and the thickness is 2 ± 0.2 mm, which can effectively protect the airbag position seat foam 2 from being pierced by the sharp corners of metal parts such as the skeleton and the airbag.
[0015] The above is only the detailed implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
