Automatic massage air cushion

Abstract

An automatic massage air cushion comprises a cover having a plurality of receptacle channels arranged in parallel for housing a set of first gasbags and a set of second gasbags, which first and second gasbags are alternatively arranged along each of the receptacle channels. The first gasbags are connected by a first air pipe system, and the second gasbags are connected by a second air pipe system. The first air pipe system is converged to an external first air inlet, and the second air pipe system is converged to an external second air inlet, both inlets being connected to an air pump. Thereby,, the air pump alternatively inflates one of the gasbag sets, whereas the other set is shrunk, activating alternatively up and down motions at the locations on the cushion under which those gasbags situate.

What is claimed is:  
     
         1 . An automatic massage air cushion, comprising: 
 a cover wherein a plurality of receptacle channels are disposed in parallel, said receptacle channels being blocked by a side plate at one end thereof;    a set of first gasbags; and,    a set of second gasbags;    said first gasbags and said second gasbags being alternatively arranged along each of said receptacle channels, said first gasbags being connected by a first air pipe system and said second gasbags being connected by a second air pipe system independent of said first air pipe system, said first air pipe system being converged to a first air inlet and said second air pipe system being converged to a second air inlet, said first air inlet and said second air inlet being connected to an air pump.    
     
     
         2 . The automatic massage air cushion of  claim 1  wherein an inner wall of said side plate and a bottom wall of said cover are respectively provided with retaining members for securing said side plate to said bottom wall of said cover.
