The invention belongs to the technical field of air springs, and particularly discloses an air spring for an improved automobile seat. The air spring comprises an air bag. The upper end and the lower end of the air bag are provided with an upper air nozzle and a lower air nozzle. Both the upper air nozzle and the lower air nozzle are correspondingly provided with an upper piston and a lower piston. The upper piston is correspondingly sleeved by the air bag. The outer wall of the upper piston is sleeved with an upper pressing ring, wherein the upper piston and the upper pressing ring form air sealing, and the lower piston is correspondingly sleeved by the air bag. The outer wall of the lower piston is sleeved with a lower pressing ring, wherein the lower piston and the lower pressing ring form air sealing. The middle portion of an inner cavity of the air bag is provided with a partition device, wherein the partition device partitions the inner cavity of the air bag into an upper independent air chamber and a lower independent air chamber. The air spring is provided with double independent air chambers, it can be guaranteed that when the air leak function of one air chamber is failed, another air chamber can still work normally, stability in the product operation process is improved greatly, it is guaranteed that the height of the automobile seat cannot be lowered due to air leakage of the air spring, and the better driving safety of drivers is guaranteed.
