Here the present invention will propose remedial measure.Therefore task of the present invention provides a kind of turnover backrest, and this backrest does not use additional supporting structure but has very high stability, very economical in the mill.This task is to solve like this according to the present invention, at least one part of backrest has at least two moulding sections that are welded to each other, at least one has crimping in these two moulding sections, this crimping is superimposed installation up and down in pairs, wherein, profiled part connects by moulding section back phase region between crimping.
The invention provides a kind of backrest, it has very high bending stiffness owing to crimping forms tubulose inclosure thing.So its temperature and the supporting structure that need not add make weight keep lighter thus.Therefore reduce whole car mass, avoided consumption of fuel.Productive costs is lower in addition.
Paired superimposed installation up and down by crimping makes moulding section be bordering on unanimity, and this has additionally reduced cost.In addition because the approaching circle of the inclosure thing that crimping forms has additionally improved bending stiffness.
In a kind of scheme of the present invention, moulding section is made blanked part by metal sheet.Make the production of backrest can be not high thus in expense aspect the production technology, individual character not too strong (nichtpersonalintensive) thereby both economical.
In a kind of favourable scheme of the present invention, bubbled by cavity to the small part that crimping forms.Increased the stability of backrest in addition by bubbling.
Advantageously, foaming material is aluminium or solid foam.These materials are very light on the one hand, thereby make the increase of backrest weight very little; The shape of itself and cavity is mated very much on the other hand.
Advantageously, moulding section is welded to each other by roll welding or laser welding.Welding by this pattern has obviously improved stability in addition, because avoided occurring splitting in the commissure, for example resembles the slide fastener phenomenon that occurs when spot welding.
In another kind of scheme of the present invention, one trim groove is arranged at the periphery of moulding section.This trim groove is used for fixing the material sleeve of clogging back seat.
In another program, at least one moulding section bearing is arranged.This bearing is used for fixing safety accessory or traveling comfort accessory.
