Shock-absorbing device for an air column foil has multiple adjacent-linked air columns each with a blow-up air check valve and a bending point for linking top and bottom parts of each air column

摘要

Each air column (1) has a blow-up check valve (2) for automatically sealing air off, after air column foils have been filled with air, or so as to prevent air from leaking out of an air column. The air columns can take the shape of rods, arches or lozenges or different other shapes or combinations of shapes. The width and size of air columns can be the same, dissimilar or a combination.
