Prior to unfolding, such curtain side airbags are usually accommodated on a roof frame and under a roof of the vehicle and unfold from there downwards along the side windows of the vehicle.
  • the vehicle occupant In the event of a side impact, the vehicle occupant is held back by the curtain side gas bag. It is, however, complicated to protect vehicle occupants in a frontal collision with only a slight overlap of the vehicles, since in this case strong rotational forces can act on the vehicle and the vehicle occupants. In addition, it may be complicated to adapt such a curtain side airbag to a vehicle contour and / or to provide a sufficient depth of the curtain side airbag over the entire installation length.

Abstract

Un sac gonflable latéral à rideau (10) comporte une extrémité longitudinale (20, 22) qui comprend une première paroi latérale et une deuxième paroi latérale opposée (14, 16) qui sont chacune formées par une partie de flan séparée et qui font chacune partie d'une paroi extérieure du sac gonflable latéral à rideau (10). Une partie de flan supplémentaire (18) est prévue qui est insérée entre les parois latérales (14, 16) à l'extrémité longitudinale (20, 22) de telle sorte que la partie de flan supplémentaire (18) forme une partie de la paroi extérieure du sac gonflable latéral à rideau (10). Dans la région de la partie de flan supplémentaire (18), la profondeur du sac gonflable latéral à rideau (10) est augmentée par rapport à une portion (24) du sac gonflable latéral à rideau (10) qui est adjacente dans la direction longitudinale (L). Dans un système de retenue d'occupant de véhicule, un sac gonflable avant est également prévu en plus du sac gonflable latéral à rideau (10). Lorsque le sac gonflable latéral à rideau (10) et le sac gonflable avant sont gonflés, une barrière est formée pour la tête d'un occupant de véhicule.
