초록 ▼

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.

대표청구항 ▼

[ We claim:] [1.] A method of making a motor vehicle seat comprising a seat proper and a seat back, each having a metal strength member, the strength member of the back being pivotally mounted on the strength member of the seat proper about a transverse horizontal axis of rotation by means of at least one hinge mechanism adapted to adjust the back angularly and to lock the back once adjusted, the strength member of the back forming a frame having:a first side upright connected to the strength member of the seat proper via said hinge mechanism;a second side upright, that is weaker than the first upright, said second upright having an upper tubular portion secured to a lower side plate which is hinged to the strength member of the seat proper; andtwo substantially horizontal cross-members respectively a bottom cross-member and a top cross-member which interconnect the two side uprights, the frame comprising a tube initially of circular cross-section and folded into a general U-shape having a web constituting the tubular portion of the second side upright and two limbs constituting the two cross-members, and the tube having a cross-section which varies in shape along its length, the web of the U-shape having a bottom length which is flattened in a vertical plane perpendicular to the axis of rotation;wherein the top cross-member has two end portions of substantially circular cross-section on either side of a central portion of substantially rectangular cross-section, each of said central and end portions having a vertical dimension, and the vertical dimension of said central portion being greater than the vertical dimension of said end portions, the central portion of the top cross-member having a top face pierced by two orifices and also a bottom face parallel to the top face and pierced by two orifices placed in register with the orifices of the top face, the seat also including a headrest which is supported by two rods each slidably mounted in a corresponding pair of said orifices; the method including a step which consists in imparting the final shape to the U-shaped tube by hydroforming, starting from an initial tube having a cross-section of section that is substantially constant.
