Description

The automobile-used bench seat that has tilting back rest

The present invention relates to a kind of automobile-used bench seat that has tilting back rest, wherein back support separated into two parts.

Bench seat is contained on the back seat in automobile.Usually can sit three people.The consequence of bench seat is holding up two effects herein: supporting occupant's back when the passenger leans against on the support of back in the process of moving on the one hand; It separates passenger accommodation and boot compartment on the other hand.In order to increase the transportation volume of automobile, the turning installation in automobile of the back support of bench seat.In addition it is separated in order to improve accommodation.Here two parts of back support only are supported on auto body or the car chassis at three some places.

The passive satety that is sitting in the outer passenger of bench seat guarantees by 3 safety strap.The passenger who is positioned at the bench seat middle part guarantees that by pelvic girdle safety is not too enough at present.In order to improve passive satety, in modern automobile, also adopt 3 safety strap for the passenger who is sitting in the middle part of the back seat.In order also to guarantee the turning property of back support in this case, the retractor of 3 middle safety strap must be fixed on the support of back.When having an accident, because automobile slows down suddenly, the passenger can sharply quicken.3 safety strap opposing passengers' this acceleration and the thing followed be to preshoot, thereby be subjected to very big power on the safety strap, and this power passes to the back support by retractor.Certain a bit supports inefficacy and can cause back the fractureing of support on vehicle body or car chassis for this power and back support.Therefore increased the risk of injury of passenger in accident that is sitting on the bench seat.

In order to improve the stability of back support, be known that on the support of back to have a supporting structure (referring to DE 295 14 752 U1).Although be provided with the stability that a supporting structure has improved back support.But increased the weight of back support owing to adding the material that uses, this will cause whole car mass to increase, thereby increase consumption of fuel.Known in addition, for improving the support high strength steel manufacturing of stability back, but this will cause the obvious raising of productive costs.

Here the present invention will propose remedial measure.Task of the present invention provides a kind of turnover back support, and this back support is not used additional supporting structure but had very high stability, so very economical in the mill.This task is to solve like this according to the present invention, and at least one part of back support has at least two moulding sections that are welded to each other, and at least one has crimping in these two moulding sections.

The invention provides a kind of back support, 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.

In a kind of scheme of the present invention, the crimping of moulding section is superimposed installation up and down in pairs.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 back support 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 back support in addition by bubbling.

Advantageously, foaming material is aluminium or solid foam.These materials are very light on the one hand, thereby make back support weight increase 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.

Accompanying drawing has provided embodiments of the invention, describes in detail below.
