Abstract:
1. An airbag for a motor vehicle, comprising: an airbag covering, the airbag being configured to be filled with gas in order to protect a person, the airbag covering having first and second airbag layers facing each other, wherein a discharge opening is formed in one of the first and second airbag layers for discharging gas out of the airbag, a connecting element configured to form a releasable connection between the first and second airbag layers, wherein, upon inflation of the airbag, the releasable connection between the first and second airbag layers is configured to counter an escape of gas through the discharging opening, wherein, upon inflation of the airbag, the connecting element is configured to interact with the airbag covering such that the releasable connection between the first and second airbag layers is released and gas can escape out of the discharge opening, wherein the first and second airbag layers upon inflation of the airbag, are configured to move away from each other such that a force is introduced into the connecting element such that the releasable connection between the first and second airbag layers is released; and a covering element for covering the discharge opening, wherein the covering element is adapted to be displaced from a first position, in which the covering element closes the discharge opening into a second position, in which the covering element is arranged with respect to the discharging opening such that gas can escape out of the airbag through the discharging opening, by pressurizing the covering element with gas after the releasing of the releasable connection, and wherein, in the first position, the covering element butts with a first area against an edge area of the discharging opening, the edge area limiting the discharging opening, wherein, in the second position, the covering element comprises a bulge such that the first area of the covering element is arranged in front of the discharging opening at a distance to the discharging opening, and wherein the covering element covers the discharging opening from an exterior space surrounding the airbag covering.
