Seat frame structure and method for forming

摘要

A tubular seat frame member is provided which has a run of ductile metal tubing with at least two headrest guide tube mounting passages formed therein and extending transversely there through. Each of the mounting passages has an upstanding wall encircling the mounting passage and extending outwardly from one side of the tubular seat frame member. Each upstanding wall is formed from an integral with the run of ductile metal tubing. Each of the mounting passages has a first end proximal the run of tubing and a second end distal the run of tubing.
