Abstract
A side-impact airbag device for a passenger cell of a motor vehicle includes a window bag which, in the active, inflated state, has a window portion which at least partially covers a side window and extends between roof support pillars. At least one of the window portions of the window bag is assigned an additional window bag pillar portion which, in the active, inflated state, at least partially covers the associated pillar relative to the passenger cell and provides a cushion against the impact, in particular, of the head and shoulder area of a passenger. In the folded-up, uninflated fitted state, the window portion of the window bag lying stowed under a lateral end portion, is bounded at the front and rear by a windscreen and a rear window respectively, of the interior lining headliner which is mounted on the roof frame and the lateral end portion of which is moved when the window bag is triggered to free the deployment path. In the folded-up fitted state, the front and/or rear window bag pillar portion lie/lies stowed under the lateral end portion of the interior lining headliner and can emerge therefrom in the direction of the A or C pillar.
