Abstract

L'invention concerne un dispositif de coussin gonflable conçu de sorte qu'une surface d'extrémité coupée ne soit pas exposée au niveau du bord périphérique le plus externe d'une section d'extrémité cousue où un trou d'évacuation de gaz est formé. Le dispositif de coussin gonflable est pourvu d'un gonfleur et d'un coussin gonflable (1). Le coussin gonflable (1) est formé sous la forme d'un sac par une section cousue (4) où les bords périphériques externes (2a,3a) d'un premier tissu de base (2) et d'un second tissu de base (3) sont cousus ensemble. La couture est réalisée de sorte qu'un tissu retourné (8) soit positionné au niveau d'un trou d'évacuation de gaz (6) formé par la fourniture d'une partie non cousue dans une partie des bords périphériques externes (2a, 3a). En raison du fait qu'une surface d'extrémité coupée n'est pas exposée au niveau du bord périphérique le plus externe de la section d'extrémité cousue où un trou d'évacuation de gaz est formé, même si le bord périphérique le plus externe de la section cousue entre en contact avec un occupant d'un véhicule lorsque le coussin gonflable est dilaté, l'occupant du véhicule n'est pas blessé.
