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.

Abstract: A wheelchair elevator includes a base, a support frame, and a movable flat. The support frame is positioned on the base, consisting of two X-shaped frames, and the movable flat is fixed on the support frame, having a receptive base respectively at two lengthwise sides a little lower than the flat. The receptive base has a lengthwise wheel passageway and a stopper behind the passageway. The flat with the support frame is raised up or lowered down by a shrinkable air tube pumped by a swing rod. Then wheelchair can be pushed on the two wheel passageways of the receptive base and stopped by the stoppers, and then the flat with the support frame is raised by pumping air into the shrinkable air tube to a needed height for boarding in a vehicle or lowered down from the vehicle.

Abstract: An aircushion bed for turning an object lying thereon automatically comprises an A airbag; a B airbag; a plurality of A1 airbags installed adjacent the A airbag and a plurality of B1 airbags being installed adjacent the B airbag; and a plurality of stripe like A2 airbags being distributed on the A airbag and a plurality of strip like B2 airbags are distributed on the B airbag. Each of the A airbag, A1 airbags and A2 airbags is connected to a respective air tube. The first air tubes are connected to a first air inlet tube. Each of the B airbag, B1 airbags and B2 airbags 21 is connected to a respective air tube. All the second air tubes are connected to a second air inlet tube. The first and second air inlets tubes are connected to an air pump.
