A protection device for a car has a seat system arranged in the interior chamber of the car with at least one seat for a person, a steering handle that can be actuated by the person sitting on the seat to cause cornering of the car, and at least one airbag which, in the event of an accident, can be filled with a gas and thus can be shifted from a stowed position to a restraining position at least partially between the steering handle and at least one part of the seat. The airbag is formed as an at least two-stage airbag.

An airbag cushion of a vehicle airbag device has a bottom surface into which the inflator is inserted, a restraining surface on the occupant side, a side surface connecting the bottom surface and the restraining surface, a recess part formed in a prescribed range in the center of the restraining surface and recessed toward the bottom surface side, and one or more tethers stretched between the recess part and the bottom surface. The recess part is formed by being pulled toward the bottom surface side by the tether during expansion and deployment. The airbag cushion further has folds and restraining parts formed along the imaginary line on the inner wall of the recess part during inflation and deployment.
