The headrest support tubes are secured to the seat frame member not by the usual welding, but by gripping the web of the member between two rings or lock-beads swaged into the metal of the tube. The first ring is swaged-out by compressing the tube. The tube, with the one ring, is then assembled into a through-hole in the web of the frame member. Then, the second ring is swaged into the metal of the tube, on the other side of the web, and the web lies gripped between the rings. The seat frame member may be an I-section extrusion, or a round tube with localised squeezed-flat areas, flanked by flanges.
Les tubes-supports d'appuie-tête sont fixés à l'élément du cadre de siège non pas au moyen de la soudure habituelle, mais en coinçant l'âme de l'élément entre deux joncs de verrouillage emboutis dans le métal du tube. Le premier jonc est expansé vers l'extérieur en comprimant le tube. Le tube, ainsi que le jonc, est ensuite assemblé dans un trou traversant dans l'âme de l'élément du cadre. Le deuxième jonc est alors embouti dans le métal du tube, de l'autre côté de l'âme, et l'âme se trouve coincée entre les joncs. L'élément de cadre du siège peut être une extrusion à section en I, ou un tube rond comportant des zones localisées aplaties entourées de brides.
