Cushion having embedded automatically-charging air tubes and method for manufacturing same

Abstract

The present invention relates to a cushion having embedded automatically-charging air tubes and a method for manufacturing same, and more specifically, to a cushion having embedded automatically-charging air tubes usable as cushioning material in bedding including beds and pillows, and various seats, and to a method for manufacturing the cushion having embedded automatically-charging air tubes. The present invention intends to provide the cushion having embedded automatically-charging air tubes and the method for manufacturing same, by arranging air tubes uniformly spaced apart inside a cavity of a mold for manufacturing a cushion, and foam-molding by injecting a cushion material inside the cavity in the mold, so that the cushion material surrounds the air tubes while integrally adhering to the outer surface of the air tubes. As a result, air can be automatically charged inside the air tubes and cushioning force with high elasticity can be provided, while enabling even distribution of a load by integrally forming the air tubes and the cushion material.
