Embodiment Construction
[0012] The present invention adopts the structural form of an inflatable flexible airbag whose shape is the same as that of an ordinary pillow, and the inflatable flexible airbag is composed of two air chambers at the front and rear of different inflation pressures; On the lower side of the neck position 1 of the human body, the flexible airbag will form its convex shape to support the neck of the human body, so that the low-pressure air chamber 3 with low gas pressure is placed on the lower side of the head position 4 of the human body. The flexible airbag will form its concave shape to support the human head. Since the middle of the flexible airbag housing 5 is filled with a gas medium, it will produce an equalizing effect on each external pressure point, that is, the high-pressure reaction force on each support point in contact with the neck position 1 of the human body is equal; In the same way, the low-pressure reaction force of each support point in contact with the head...
