Abstract: A method for making a web-shaped structure formed by plastic material, comprising: forming a first plastic member in a mold by a first ejection molding process, the first plastic member being provided with a plurality of combination strips, and then forming a second plastic member integrally combined with the first plastic member by a second ejection molding process, wherein the second plastic member is provided with a plurality of combination strips which are interwoven with the combination strips of the first plastic member, thus forming a web-shaped structure.

Abstract: The present invention relates to an elastic deformable cushion, an elastoplastic knee of which is provided at the thrust surface with curved portion so as to improve the compressive rigidity. On the vertical thrust surface of the elastoplastic knee piece is provided with multi layers of arc-curved portion for improving the buffering effect. Furthermore, the elastoplastic knee and the elastoplastic knee piece are unnecessarily formed in the shape of a helical structure. In this case, the elastic deformable cushion in accordance with the present invention can be easily produced, the corresponding production cost will be reduced.
