    • Disclosed is a system and method for inflating airbags. The system includes a series of pair of pulleys arranged in two parallel rows. The two pulleys of the pair are in the first row and the second row. Each pulley having its periphery configured with a semicircular concave groove that extends between two edges, wherein the semicircular concave grooves of a pair of pulleys form a tunnel. Each pulley in the first row can rotate clockwise, while each pulley in the second row rotates anticlockwise. A cylindrical air tube can be positioned in the tunnel wherein the air tube is closed at one end and connected to a compressed air source at opposite end. The air tube has spaced apertures along its length, wherein the apertures are located at bottom of the air tube. An airbag with two flaps can be mounted on the inflation system, wherein the two flaps are pressed on the air tube by the pair of pulleys and each pair of pulleys can drag the flaps, and thus the airbag, forward on the air tube.
