1. An airbag module for a restraint device , comprising a seat-integrated side airbag, a slidable actuator, and an outlet opening,
wherein the airbag comprises a shoulder chamber and a head chamber which are separated by a partition and fluidically connected to each other via an overflow opening that provides fluid communication from the shoulder chamber to the head chamber through the partition, the overflow opening comprising a material layer having a tensioned condition configured to cover and seal the overflow opening so that only the shoulder chamber inflates, and a released condition configured to uncover the overflow opening to provide fluid communication between the shoulder chamber and head chamber so that both the shoulder chamber and head chamber inflate,
wherein the outlet opening has an open condition for allowing gas to flow out of the airbag, and a closed condition for blocking gas from flowing out of the airbag,
wherein the actuator has a blocking position in which the material layer is held in the tensioned condition and the outlet opening is placed in the open condition, the blocking position being configured to inflate only the shoulder portion, the actuator having a release position in which the material layer is placed in the released condition and the outlet opening is placed in the closed condition, the release position being configured to inflate both the shoulder portion and head.
