To this end, an air cushion for an airbag of a motor vehicle is provided, having a sleeve with at least one opening and a closure element arranged on the at least one opening in order to at least partially prevent air from flowing from a first direction, Furthermore, the closure element is flexible and has a channel-shaped design at least upon the flow of air from a second direction opposite the first direction. The closure element thus has the effect of a check valve.
