Abstract: An air inflation cushion with cells having helical edges comprises a lower sheet; an upper cushion portion adhered upon the lower sheet; the upper cushion portion including at least one air inflation cell; each air inflation cell having an approximate rectangular cross section and being supported by four helical edges for enhancing the structure of the cell; upper ends of the helical edges being formed as rectangular upper planes; the four helical edges dividing the air inflation cell into four lateral surfaces; a lower portion of each lateral surface being formed with a convex cambered protrusion; and an air tap at one of the cells and extending from one of the helical edges. The air inflation cushion is made of black rubber. The cell is extended with a communication trench which causes two adjacent cells are communicated to one another.
