[0023] The following will further describe the present utility model in detail through specific embodiments in conjunction with the drawings.

[0024] Referring to Figure 1 , Figure 1 is a partial structural cross-sectional view of an example of the present utility model applied to a seat. An airbag guiding structure for an automotive seat backrest provided by the present utility model includes an airbag guiding cloth 1, an airbag 2, a non-woven bag 3, a support plate 4, and a side wing skin 5. The airbag guiding cloth 1 is disposed inside the seat backrest and adjacent to the side wing skin 5 of the seat. The airbag 2 is disposed inside the airbag guiding cloth 1. The non-woven bag 3 is disposed on the side wing skin 5. As a preferred embodiment, the non-woven bag 3 and the airbag guiding cloth 1 are sewn on the side wing skin 5. The airbag guiding cloth 1 is disposed adjacent to the non-woven bag 3. A support plate 4 is disposed inside the non-woven bag 3. The thickness of the support plate 4 is 1 mm - 3 mm. The support plate 4 is used to block the opening at the side of the airbag of the seat foam 7. The size of the support plate 4 should be at least able to block the opening at the side of the airbag of the seat foam 7. In order to maintain the appearance of the seat side wing, the size of the support plate 4 can be close to the size of the seat side wing. As a preferred embodiment, the support plate 4 is made of a PP plate, and the thickness of the PP plate is 2 mm.

[0025] In another embodiment, an airbag guiding structure for an automotive seat backrest further includes an airbag bracket 6. The airbag guiding cloth 1 is disposed on the airbag bracket 6, and the airbag guiding cloth 1 can be fixed on the airbag bracket 6 by nuts.

[0026] The following will refer to Figure 1 to illustrate the working principle of the present utility model.

[0027] The non-woven fabric bag 3 and the airbag guiding cloth 1 are sewn on the side wing skin 5. The support plate 4 is inserted into the non-woven fabric bag 3 to block the opening at the side airbag of the seat foam 7. The side of the seat foam 7 is opened at the airbag position to ensure that the side of the seat foam 7 is at the same height as the airbag, saving the seat Y-direction space. The airbag 2 is inserted into the airbag guiding cloth 1 and fixed on the airbag bracket 6 by nuts or arranged beside the skeleton side plate and supported by the skeleton side plate. When the airbag 2 expands, the airbag 2 is guided by the airbag guiding cloth 1 and the support plate 4 and quickly pops out and unfolds in a preset direction. The utility model solves the problem of insufficient seat Y-direction space. Under the condition of meeting the blasting safety of the seat airbag and the fine appearance of the seat side wing, the width of the seat side wing can be reduced, the width of the seat core part can be increased, and the seat comfort can be improved.

[0028] The above is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the protection scope of the claims.
