A process for the preparation of a cushioning element with an integrated fire protection layer which is equipped with these elements as well as comfort article.

摘要

The present invention relates to a method of producing a bolster element (16) integrally with a fire-resistant layer which encases it, which bolster element is made of an inflammable polymer foam and is obtained by moulding. The process comprises the following steps: i) producing impervious and deformable thin layers by coating the internal face of an elastic fabric having a high degree of flame resistance with the aid of a composition (15) made of an elastic polymer material, especially an elastomer, which comprises a filler intended to render it flame-retarding and which is compatible with the material of which the bolster element is composed, ii) covering the walls of the mould (1) used for moulding the bolster element (16) with the aid of the impervious and deformable thin layers (11, 12) thus coated, iii) lining the corresponding walls of the mould with these impervious covering layers, by suction, iv) injection into the mould of the polymer material (17) of which the bolster is composed. Application to the production of articles of comfort in the transport industry, especially in aeronautics. IMAGE
