Abstract (en)

[origin: EP0856271A2] A base for chairs, armchairs or the like, comprising tubular or open-profile metal spokes (15) which are radially joined, at their ends (16), to a likewise metallic central structure (17) on which a post for a seat is fitted. The central structure (17) comprises at least two flat portions (18) which are perimetrically provided with a folded rim (20), between which the ends (16) of the spokes (15) are interposed. The flat portions are welded to the spokes by electric pressure welding which produces the melting and at least partial penetration of the folded rims in the softened ends of the metal spoke and the folded rims are thicker than the metal spokes. <IMAGE>
