DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a lounger-type air massager in which bags are set at predetermined positions in a lounger and are inflated and deflated as compressed air is fed into and discharged from them, so that the body of a user seated on the lounger is intermittently pressed to be massaged by the bags.
BACKGROUND ART
A lounger-type air massager of the aforesaid type has been made to be known by Jpn. Pat. Appln. KOKOKU Publication No. 3-41185, for example. In this conventional lounger-type air massager, the whole outer surface of the seat back (backrest portion) of a lounger is formed to have the shape of a physiologically curved surface that substantially fits the curvature of the vertebral column of the human body. A plurality of elongated small projections each of which has a round cross section are arranged along the physiologically curved surface, each of the projections extending substantially all over the width of the backrest portion. Elongated small projections each of which has a round cross section are further arranged in the seat portion of the lounger at positions corresponding to the buttocks and thighs of the body of a person seated on the seat portion, each of the projections extending substantially all over the width of the seat portion. Bags capable of inflation and deflation are arranged individually on these projections, and feed of compressed air into these bags is repeatedly started and stopped while a user is seated on the lounger-type air massager. When the compressed air is fed into those bags during this repetition, the bags inflate and press the body of the user seated on the lounger. When the feed of the compressed air into those bags is stopped, the bags are pressed by the weight of the aforesaid body, so that the air in the bags is discharged, whereupon the bags deflate. The pressurization and depressurization of the user's body, caused by such inflation and deflation of the bags, produces a massage effect for the user's body.
In the lounger-type air massager described in Jpn. Pat. Appln. KOKOKU Publication No. 3-41185, these bags are fixed to the opposite ends of the backrest portion and those of the seat portion in their width direction by fixing means, such as adhesion or welding (see the 8th to 13th lines of the left column on the 4th page and FIGS. 5a and 5b of the aforesaid KOKOKU Publication).
Jpn. Pat. Appln. KOKOKU Publication No. 3-41185 further describes that the shape of the projecting end of each of the aforesaid projections is selected in order to set a direction in which the body is pressed by each of the inflated bags with a maximum massage effect (see the 4th to 11th lines of the right column on the 4th page and FIG. 13 of the aforesaid KOKOKU Publication). To this end, the rear-end-side (i.e., backrest-side) slope of each projection of the seat portion is made gentler than the front-end-side (i.e., side opposite to the backrest side) slope, and the bag is placed on the gentler rear-end-side slope. When compressed air is fed into this bag, the bag inflates diagonally upward and rearward, that is, in a direction substantially perpendicular to its corresponding gentler slope, and presses the thighs and buttocks of the body of the person seated on the seat portion diagonally upward and rearward. Thereupon, the body of the person seated on the seat portion meets with resistance from the backrest portion, so that the massage effect of the bags on the seat portion for the thighs and buttocks of the body is improved.
In the lounger-type air massager described in Jpn. Pat. Appln. KOKOKU Publication No. 3-41185, however, the person seated on the lounger-type air massager can perceive the projecting ends of a plurality of projections on the seat portion and the backrest portion when the bags deflate. Accordingly, the seated person suffers an unnatural sense, and cannot be seated at ease on the lounger-type air massager.
In the lounger-type air massager described in Jpn. Pat. Appln. KOKOKU Publication No. 3-41185, moreover, since each of the ba
