Document Type and Number:
WIPO Patent Application WO/2021/156240
Kind Code:
A1
Abstract:
The invention relates to an expandable tubular element (3, 37) for a fluid-inflatable cylinder, comprising a peripheral wall (7) that is fluid-tight and formed by a plurality of panels (9) connected in pairs by substantially rectilinear links (11) each representing a pivot axis, the panels (9) being more rigid than the links (11), so that two panels (9) adjacent to a link (11) can rotate about the pivot axis represented by this link (11), each end of a link (11) being connected to at least two ends of other links (11) so as to define a node (13), each node (13) having a thickness greater than the minimum thickness of the adjacent links (11). The invention also relates to a method for producing such an expandable tubular element (3, 37), as well as a fluid-inflatable cylinder (1, 35, 39) comprising such an expandable tubular element (3, 37).
