Abstract
An air massaging apparatus utilizes a plurality of inflatable air bags of elongated configuration which are arranged in side-by-side relation along a line and supplied with compressed air from a pump to inflate. A distributor is provided to channel the compressed air from the pump selectively to the air bags for inflating the air bags one after another sequentially in a predetermined primary direction along the line of arrangement in such a manner as to inflate at least one air bag at a time while allowing the compressed air to escape from the remaining air bags. The distributor is controlled to inflate the air bags temporarily in a reverse order over a limited number of the air bags during an overall operation of sequentially inflating the air bags in the predetermined primary direction.
