a side airbag comprising a shoulder chamber and a head chamber 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 having a closed condition configured to cover and seal the overflow opening so that only the shoulder chamber inflates, and an open 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; and
an actuator having a first condition configured to hold the overflow opening in the closed condition so that only the shoulder portion is inflated in response to a crash, and a second condition configured to release the overflow opening to the open condition so that both the shoulder portion and head portion are inflated in response to a crash.
