The invention discloses a spring type columnar automobile airbag which comprises an airbag body and a gas generator, wherein the airbag body is in a cylindrical structure, and the gas generator is arranged on the bottom surface of the airbag body; at least two groups of tightening rings are arranged on the periphery of the cylindrical surface of the airbag body from the bottom side to the top side. The integral structure of the airbag body is cylindrical, and under the action of the tightening rings, the airbag body can form multiple spring type columnar structures after being spread; the top surface of each columnar structure is a plane, so that the surface area contact with the human body is larger. In addition, when the airbag is stressed, the gas is pressed to be deformed and compressed, and the multiple segments of structures of the airbag body can also be extruded and merged. Thus, the airbag can provide a better buffer effect and greater protection to the human body.
