The invention discloses a vertical pressing type automotive airbag which comprises an airbag body mounted at the position of the ceiling of an automobile. The stress direction upon the airbag body is in the vertical direction downward from right above, force-bearing points of the airbag body is fan-shaped multi-axial force axes, and the symmetric axis of the fan-shaped multi-axial force axes is a vertically downward axis. The stress axis lines are scattered, so that total transverse impact in the horizontal direction or close to the horizontal direction can be effectively buffered after bumping occurs; when an automobile accident happens or especially when an automobile is in rear-end collision with a truck or in brake fail, the human head, the neck, the chest and the while body can be effectively protected.
