Meanwhile, although not specifically shown in the backrest portion 200, in order to use the chair assembly with the function of inducing an extension posture according to the present invention, the backrest portion 200, which was folded relative to the seat portion 100, is unfolded and inflated at the same time. An air bladder device may be embedded so that the user sitting on the Ola chair assembly can maintain an extended posture.

That is, when the air bag device is not in use, when the backrest portion 200 is in contact with the seat portion 100 and folded, it is distorted and its volume is reduced, and then the moment the backrest portion 200 is unfolded, it combines with air and inflates. A structure that expands as it rises could be applied.

In other words, in the air bag device, a preset volume of air and cotton mixture or synthetic fiber made of polyester or nylon is constantly swelled, and the user's back in contact with the backrest 200 forms a C-shaped curve, creating a definite extension posture. To make it happen.

As described above, it can be seen that the basic technical idea of the present invention is to provide a chair assembly with an extension posture inducing function that can correctly guide children's sitting posture to an extension posture.

And, of course, many other modifications and applications are possible for those skilled in the art within the scope of the basic technical idea of the present invention.
