Abstract

L'invention concerne un dispositif de coussin pneumatique avant d'un véhicule automobile comprenant : un coussin pneumatique limitant un espace d'expansion principal et comprenant une partie avant faisant face à un passager pendant l'expansion; et au moins une partie de retenue de tête qui fait saillie à partir de la partie avant du coussin pneumatique et qui est configurée pour, lorsqu'une collision de tête excentrique se produit pour appliquer un impact à une partie prédéterminée de l'extérieur le long de la direction de la largeur de la partie avant d'un véhicule automobile, empêcher que la tête du passager qui entre en collision avec la partie avant du coussin pneumatique ne se déplace vers le côté de collision et ne soit déformée par une force de collision de la tête du passager pour attraper la tête du passager. Il est ainsi possible d'empêcher que la tête du passager ne se déplace tout en tournant en direction du côté de collision, ce qui permet de réduire efficacement les blessures subies par la tête et le cou du passager.
