Abstract

The invention relates to a passenger gas bag protection device which comprises a gas bag which, in relation to an inflated state, has a rear wall and a front wall which includes a center section and onto which a passenger strikes in the case of an accident. The gas bag, from a viewpoint of the passenger, has a round outer contour with a specific width and height in the inflated state. The width of the outer contour distinctly exceeds the height. In the inflated state the front wall has a depression opening out to the outside in the manner of a slit. The slit runs in a direction of the width of the gas bag. A restraint means is provided and the depression is formed in that on inflation of the gas bag a center section of the front wall is prevented from moving by means of the restraint means.
