Cushioning element, footwear, insole, deformable filling, and envelope
First Claim
1. Cushioning element for footwear, having a deformable filling and an envelope that encloses the deformable filling, wherein the envelope is arranged for forming at least one flow channel, wherein, in use, at least part of the deformable filling flows into the at least one flow channel as a result of increased pressure of the deformable filling caused by a mechanical load, wherein the deformable filling contains solid bodies and further contains a lubricating fluid for mutually lubricating the solid bodies, wherein the at least one flow channel is dimensioned for hindering entrance of the solid bodies into the at least one flow channel during cushioning,wherein the envelope has an elastically variable volume, andwherein the envelope is arranged for forming the at least one flow channel by developing, substantially reversibly, a bulge in at least one deformable portion as a result of increased pressure of the deformable filling exerted on the at least one deformable portion, caused by the mechanical load, andwherein the at least one flow channel is dimensioned for inhibiting entrance of the solid bodies into the at least one flow channel during cushioning.

Abstract
Cushioning element (4) for footwear, having a deformable filling (12) and an envelope (10) that encloses the deformable filling. The envelope is arranged for forming at least one flow channel (837). In use, at least part of the deformable filling flows into the at least one flow channel as a result of increased pressure of the deformable filling caused by a mechanical load The deformable filling contains solid bodies and further contains a lubricating fluid for mutually lubricating the solid bodies. A dimension of the at least one flow channel is arranged for hindering entrance of the solid bodies into the at least one flow channel during cushioning.

24. Cushioning element for footwear, having a deformable filling and an envelope that encloses the deformable filling, wherein the envelope is arranged for forming at least one flow channel, wherein the envelope is provided with at least one deformable portion that has a reduced rigidity compared to a remaining portion of the envelope, wherein the cushioning element is arranged for developing, substantially reversibly, a bulge in the at least one deformable portion as a result of increased pressure of the deformable filling exerted on the at least one deformable portion, caused by a mechanical load, and the bulge is formed in a cavity of a support member, and
wherein the deformable filling contains solid bodies, and wherein the at least one flow channel is dimensioned for inhibiting entrance of the solid bodies into the at least one flow channel during cushioning.
