Air cushion pad
An air cushion pad includes at least two sheet members, which are made of resilient materials. Each sheet member forms a plurality of hollow tubes projecting therefrom and the tubes are connected to each other by a substantially flat plate. The tubes of one sheet member and the tubes of the other sheet member are alternately fit to each other in an opposing manner to form the air cushion pad. When an external impact force is applied in a top down manner, the air cushion pad absorbs the impact force and undergoes sideways deformation so as to convert the impact force into a transverse to thereby realize shock absorption and eliminate damage caused by downward action of the impact force to provide the function of protection.
