Flexible air cushion unit and assembly structure

Abstract

The present invention provides an air cushion unit that can be assembled into any shape and dimension, and more particularly to an innovative one which is prefabricated with interconnected air rings, air pipes and air chambers along with close-packed air columns and air nozzles, allowing to adjust flexibly the pressure value. So, it can be widely applied to meet different sitting or lying demands under various stress states.

1 . A flexible air cushion unit and assembly structure, comprising:
 a plurality of air rings, which are located at the center of air chamber and air pipe, and separately interconnected with them;   a plurality of air pipes, which are arranged around air ring in a crosswise form;   a plurality of air chambers, separately located at both sides of every air pipe for charging air;   air cushion unit, which is formed by interconnection of prefabricated air rings, air pipes and air chambers;   wherein the air cushion units are linked by an air column into a bigger air cushion device;   wherein the air column is composed of a main body and screws at both sides, air holes are centrally preset, and tapered mouths at both ends are separately inserted into air pipes, and then fastened by the screws;   wherein said air columns are connected with optional air pipes of nearby air cushion unit;   wherein the tapered mouths of air columns and the screws are arranged at one side or two sides;   wherein said air cushions of different sizes are formed by air cushion units of different quantities;   wherein said air cushions of different shapes are formed by air cushion units of different quantities;   wherein the quantity of air rings, air pipes and air chambers for every air cushion unit can be increased or reduced.
