ABSTRACT:
A metal frame for chairs with tubular elements, comprising two inverted U-shaped elements (10), which form the legs, two L-shaped elements (11), which form the support for the seat and the back and are each arranged next to one of the preceding elements, and two rod-like cross-members (12), which are arranged in a lower region so as to join portions of the inverted U-shaped elements and of the L-shaped elements. The cross-members (12) are joined to the other elements by projection welding at a pair of protrusions (13) determined by corresponding recesses (14) in the cross-section, formed by a flattening plastic deformation.
