Abstract
A massaging system includes a base sheet carrying a plurality of expandable bags arranged in a plane of the base sheet, and a charging and discharging unit connected to the bags for selectively supplying and discharging a pressurized fluid into and from the bags so as to inflate and deflate the bags, selectively. At least one applicator projects from each of the bags in contact with a portion of a human body for applying a massaging action. Each bag has a flexible top end capable of deforming into a curved contour when being inflated. The applicator is made of a hard material and projects directly from the top end wall of the bag as an integral part of the bag such that the applicator is caused to displace in a direction different from a direction along which the bag inflates and deflates principally, as a consequence of that the flexible top end wall deforms into the curved contour. Thus, the applicator can concentrate a massaging force resulting from the inflation of the bag to a particular portion of the user's body, giving a relatively strong local massage action sufficient for optimum treatment. Further, since the applicator takes a lateral movement in the direction generally …
