ABSTRACT:
A method of making a vehicle seat in which the strength member of the back has a first upright connected to the strength member of the seat proper by a hinge mechanism, a second upright that is not as strong as the first and that is hinged to the strength member of the seat proper, and two horizontal cross-members, the two cross-members and the top portion of the second upright being constituted by a tube folded into a general U-shape and of section that varies along its length. The method includes a step which consists in imparting the final shape to the tube by hydroforming, starting from an initial tube of substantially constant section.
