A vehicle cabin having a vehicle seat is provided and the vehicle seat is aligned in a frontal direction. An instrument panel extends on the front side toward the vehicle seat and forms a foot well in the perpendicular projection onto a projection plane that is defined by a vehicle floor or sections thereof. A leg space extends between the foot well and the vehicle seat, and an airbag system is provided that is integrated at least in sections in the instrument panel and which has a prebag and an airbag. In the inflated state, the airbag is supported on the prebag. In the projection plane, the leg space in the frontal direction is at least twice as long, preferably at least three times as long as the foot well.
