Abstract: An airbag for a passenger protection device affords optimum protection to a passenger while being produced using only a small amount of material and, therefore, in an economical manner. This is achieved by providing the airbag with at least two partial airbags that are fluidically connected to each other. At least one tensioning device draws the at least two partial airbags towards each other, thereby tensioning them together.

Abstract: An airbag comprises a bag which is bent in the shape of an arrow ‘<’ in a deployed state, and a connection member which is arranged on a side of the bag, facing a vehicle body, and connects the upper and lower ends of the bag with each other. A longitudinal intermediate portion of the bag projects toward a vehicle occupant. A space is defined between the projecting intermediate portion and the connection member. The head of the vehicle occupant initially comes into contact with the intermediate portion and then presses the bag toward the vehicle body. Upper and lower parts of the bag which extend upward and downward from the intermediate portion cooperate with the connection member to define a triangular space.
