A driver airbag which applies only small forces to the upper abdominal region of the driver and which provides additional possibilities of adaptivity is described. This driver airbag comprises a front layer pointing towards the driver when the driver airbag is deployed and a back layer pointing towards the steering wheel when the driver airbag is deployed. Front layer and back layer are circumferentially connected to each other by an edge connection and define a chamber (20). Additionally a line-shaped inner connection (25) connecting the front layer and the back layer in a lower area of the driver airbag is provided. This inner connection encircles at least partially a sub-chamber (23) of the chamber (20), such that the chamber (20) comprises a main chamber (22) and this sub-chamber (23). The back layer has at least one ventilation hole which connects the sub-chamber (23) with the environment (Fig. 4).
