Description

[0001]
BACKGROUND OF THE INVENTION
More specifically, the present invention relates to an air massager, and more specifically, when sheets are welded in multiple layers to form an air chamber, the strength of each welded portion of the multiple sheets is made approximately equal to try to make the strength of each air chamber approximately equal. It is related to the technology.
[0002]
[Prior art]
Conventionally, when multiple air chambers are formed, multiple sheets with stacked sheets are welded at the same location.
[0003]
[Problems to be solved by the invention]
By the way, when multiple sheets with stacked sheets are welded at the same location, it is difficult to make the molten state of each sheet uniform, so the strength of the welded portion between the sheets cannot be made equal, and the strength of the welded portion is increased. Variations occurred, and as a result, the life of the air chamber in the air massager was short.
[0004]
Further, in the conventional air massager, since the thickness of the opposing sheets formed by the air chamber is equal, a large amount of air is required when the inner and outer sheets expand equally to expand the air chamber. To do.
[0005]
Furthermore, the sheet | seat which comprises an air chamber closely_contact | adheres and it has become a thing which air does not enter easily.
[0006]
The present invention has been made in view of such a problem, and in the case where an air chamber is formed by multiple welding of sheets, the strength of the multiple air chambers is made by substantially equalizing the strength of each welded portion of the multiple sheets. The main purpose is to make the air chambers substantially equal, and the other purpose is to reduce the amount of air for expanding the air chamber to the outside. Further, the sheets constituting the air chamber should not be in close contact with each other. It is another object of the present invention to provide an air massager that further aims to be able to smoothly supply air to the air chamber.
[0007]
