Abstract
In an air massager, a seat, backrest, etc. are provided with cushion units. Each cushion unit includes a pad member, consisting mainly of a fiber-filler, and airbag apparatus put on top of the pad member. The airbag apparatus can be inflated or deflated as air is fed into or discharged from it by means of a pumping device. A compressible distance in the thickness-direction of the pad member is greater than a maximum inflated thickness of the airbag apparatus. The pad member has a thickness, softness, and restorability such that it allows the inflated airbag apparatus to go down into the fiber-filler and incline along a seater's body surface when the airbag apparatus is pressed by the body surface.
