MAT-SHAPED AIR MASSAGER

PROBLEM TO BE SOLVED: To improve a massage effect by reducing the area of a massager in contact with a human body and hardly sinking the human body in a quilt or a bed mat. SOLUTION: A mat 20 to be installed on the quilt or the like is provided with plural air bag bodies 30 extended across the direction of height, and air is repeated supplied/exhausted to these air bag bodies 30 in the prescribed order for prescribed time. Concerning the respective air bag bodies 30, four hollow U-shaped spherical objects are respectively joined while being turned down on a common substrate and the respective U-shaped spherical bodies 33 are linked through a communication pipe. When air is sent from a pumping device 50, the U-shaped spherical bodies 33 are expanded. Since the apex parts of the U-shaped spherical bodies 33 are in contact with the human body lying on the mat, point-contact is provided and since the bottom areas of the U-shaped spherical bodies 33 are large and coupled with the substrate, on the other hand, the human body hardly sinks in the quilt or the bed mat so that the massage effect can be improved.
