Abstract

La présente invention est configurée de telle sorte qu'une réduction du couple de serrage soit empêchée par la fixation d'un dispositif de coussin de sécurité gonflable à un élément structurel d'un siège de véhicule par un boulon et un écrou. Un goujon (125) est élevé à partir d'un gonfleur (120), et une ouverture (112) à travers laquelle le goujon (125) est inséré est formée dans la paroi de support de gonfleur (111) de l'élément de revêtement (110) d'un siège de véhicule. Le goujon (125) est inséré à travers l'ouverture (112) dans l'élément de revêtement (110), une plaque (123) est montée sur le goujon inséré (125), et un écrou (non représenté) est serré de façon à fixer la plaque (123) à un cadre latéral (non représenté). La présente invention est configurée de telle sorte que l'élément de revêtement (110) ne soit pas fixé par l'écrou lors de la fixation du goujon (125) et de l'écrou (126) l'un à l'autre.
