Title:
PERSONALIZED AIR CUSHION SHOE
Document Type and Number:
WIPO Patent Application WO/2021/151268
Kind Code:
A1
Abstract:
Provided is an air cushion, which is divided into two or more relatively independent air bags in different areas, and the independent air bags are in communication by means of one or more flow limiting valves. If the air cushion is subjected to a non-uniform impact force, under the action of a pressure difference, the air in the air cushion flows, in a limited manner, under the control of the flow limiting valve, such that the relationship between an increase in pressure and the deformation of the air cushion is more linear. The air pressure difference exists between the relatively independent air bags in different areas of the air cushion within a certain time, different buffer and support properties are exhibited, and the balance between the support force and the damping effect is obtained.
