A front passenger airbag (5) is described for arrangement in the instrument panel (20) of a motor vehicle. It has an airbag envelope (10) having an impact area (11) and lateral surfaces extending from the impact area (11). In order to use small gas generators and to reduce the danger for a passenger in a non-standard seating position, the impact area (11) is nearly exclusively allocated to the front passenger's (I) head or head and shoulder area, the impact area (11) having a concave shape when the airbag envelope (10) is fully expanded and free of external forces, such that a left and right section of the impact area (11) respectively extend farther into the interior of the motor vehicle than a central section.
