초록

A backrest structure for a vehicle seat comprises two hydroformed, tubular, horizontal crosspieces and vertical uprights engaged without any clearance in orifices punched into these crosspieces during hydroforming.

대표청구항 ▼

1. A method of manufacturing a backrest structure of a seat for a vehicle, this structure comprising:a tubular-shaped, rigid, bottom horizontal crosspiece delimiting a certain interior volume and comprising a bottom part and a top part, a tubular-shaped, rigid, top horizontal crosspiece delimiting a certain interior volume and comprising a bottom part and a top part, and at least first and second rigid, substantially vertical uprights, each of which extends between bottom and top ends joined respectively to the bottom and top crosspieces, said method comprising at least one step in which the bottom and top crosspieces are shaped by hydroforming, characterized in that when hydroforming the bottom crosspiece, as the interior volume of this bottom crosspiece is being filled with pressurized liquid, at least first and second pairs of orifices are punched into said bottom crosspiece, the first pair of orifices in the bottom crosspiece comprising two reciprocally matching orifices arranged respectively in the top part and in the bottom part of the bottom crosspiece and having sections matching the bottom end of the first upright, and the second pair of orifices of the bottom crosspiece comprising two reciprocally matching orifices arranged respectively in the top part and in the bottom part of the bottom crosspiece and having sections matching the bottom end of the second upright, in that when hydroforming the top crosspiece, as the interior volume of this top crosspiece is being filled with pressurized liquid, at least first and second pairs of orifices are punched into said top crosspiece, the first pair of orifices of the top crosspiece comprising two reciprocally matching orifices arranged respectively in the bottom part and in the top part of the top crosspiece and having sections matching the top end of the first upright, and the second pair of orifices of the top crosspiece comprising two reciprocally matching orifices arranged respectively in the bottom part and in the top part of the top crosspiece and having sections matching the top end of the second upright, and in that the hydroforming step is followed by an assembly step, in which: the bottom ends of the first and second uprights are engaged without any clearance respectively in the first and second pairs of orifices of the bottom crosspiece, the top ends of the first and second uprights are engaged without any clearance respectively in the first and second pairs of orifices of the top crosspiece, and the uprights are definitively joined to the crosspieces in order to prevent the uprights from slipping out, mechanical strength essentially being imparted to the backrest structure by the location of the uprights in the crosspieces without any clearance.
