Abstract

Airbag (10) pour un véhicule à moteur, pourvu d'une structure de support (12), comprenant une pluralité d'éléments de volume (14, 16, 18), qui peut passer d'une position de stockage à une position de retenue lorsque les éléments de volume (14, 16, 18) sont soumis à l'action d'un milieu et qui, dans sa position de retenue, entoure au moins par endroits un volume de retenue (20) de l'airbag (10), rempli d'un milieu gazeux. Selon l'invention, la structure de support (12) comporte une zone de base comprenant une partie des éléments de volume (14, 16, 18) qui, dans la position de retenue, peut être amenée de manière à reposer contre le pare-brise (36) du véhicule à moteur, et à partir de laquelle, dans la position de retenue, des zones latérales (32, 34) de la structure de support (12), comportant chacune une autre partie des éléments de volume (14, 16, 18), s'étendent vers l'arrière des deux côtés, au moins sensiblement dans la direction longitudinale du véhicule.
