Abstract
The utility model discloses a kind of car seat back frame, the backrest backboard that comprises frame shape structure, the outer ring portion of this backrest backboard turns down forward and forms backrest frame, the inner ring edge of this backrest backboard turns down forward formation flange, on the top of described backrest backboard, be provided with at least two headrest tubes, this headrest tube passes described backrest frame, and described headrest tube antetheca is provided with front demoulding mouth, the rear wall of described headrest tube is provided with rear demoulding mouth, and described front demoulding mouth is relative arranged in a crossed manner with rear demoulding mouth.The remarkable result of this scheme is to have increased the intensity of seat back-rest framework, the weight of the increase backrest frames of exceeding, improved backrest frames service life, on headrest tube, the disposable demoulding of energy, makes releasing process more simple and reliable, can save manpower and the energy cost of demoulding link; Simultaneously because there being the existence of front demoulding mouth and rear demoulding mouth, meeting under the prerequisite of the mechanical strength coordinating between head rest pole and headrest tube, saved raw MAT'L, further reduced cost.
Description
Technical field
The utility model relates to field of automobile seats, specifically, relates to a kind of car seat back frame.
Background technology
Automotive seat comprise backrest and seat frame, for improving the traveling comfort of taking, how on backrest, to be provided with headrest, automotive seat are supported by automobile chair frame, automobile chair frame comprises backrest frames and seat frame skeleton, at present for the former front-row seats backrest of automobile stamping steel plate skeleton, the novel semiclosed magnesium alloy backrest frames structure that technical personnel proposes to adopt magnesium alloy extrusion tubing and punching press plate to combine is substituted, this structure and two-way recliner form the integrated backrest frames of sealing, can reach 48.8% loss of weight ratio.
Yet the intensity of magnesium alloy is relatively low, need to promote the intensity of backrest frames, but not so the weight of not extra too much increase backrest frames used magnesium alloy to make backrest frames and just lost meaning; Meanwhile, the tubular structure that the pillow conduit that excuse is traditional is sealing, after backrest frames is one-body molded; core rod in headrest conduit cannot once take out; the technique of need to independently loosing core just can complete the demoulding of headrest conduit, in large-scale production, can increase productive costs.
Utility model content
For solving above technical matters, the utility model provides a kind of Novel car seat backrest frames, the advantage of making it have and save material, reduce weight, intensity is reliable, is convenient to the demoulding.
The technical solution of the utility model is as follows:
A kind of car seat back frame, its key is: the backrest backboard that comprises frame shape structure, the outer ring portion of this backrest backboard turns down forward and forms backrest frame, the inner ring edge of this backrest backboard turns down forward formation flange, on the top of described backrest backboard, be provided with at least two headrest tubes, this headrest tube passes described backrest frame, and described headrest tube antetheca is provided with front demoulding mouth, the rear wall of described headrest tube is provided with rear demoulding mouth, and described front demoulding mouth is relative arranged in a crossed manner with rear demoulding mouth.
The remarkable result of above technical scheme is, backrest frame and backrest composition of backboards form steel angle structure, improved to a great extent the intensity of backrest frames, therefore the thickness of backrest frame and backrest backboard can suitably reduce, this has just saved material, has reduced weight, and does not affect the intensity of backrest frames; Simultaneously in to the one-body molded process of automobile back skeleton, mould can disposable the past demoulding mouth and rear demoulding mouth in take out, just can form headrest and leading, be convenient in demoulding, productive costs reduces.
In order better to realize the utility model, may further be:
The thickness of above-mentioned backrest frame and backrest backboard is 2～3mm, arc transition between described backrest frame and described backrest backboard, angle between the vertical side plate of described backrest frame and described backrest backboard is 91 °～95 °, rounding after the edge of the left side board of described backrest frame, right side board and epipleural thickens, edge's rounding of described flange.In this scheme, for the ease of the demoulding, angle, in order to make the human body human body of more fitting, improves the traveling comfort of passenger, and the angle between vertical side plate and described backrest backboard is difficult for being greater than 95 degree; Above two place's roundings, further gain in strength.
Between above-mentioned backrest frame and described backrest backboard, be provided with L shaped boss, the medial surface long-armed and described backrest frame of this boss is affixed, and the leading flank of the galianconism of described boss and described backrest backboard is affixed.In this design, boss can be fixing more firm with backrest frame and backrest backboard, met the laws and regulations requirement of automotive interior protrusion.
Angle between the upper and lower of the vertical side plate of above-mentioned backrest frame and described backrest backboard is 91 °, angle between the middle part of the vertical side plate of described backrest frame and described backrest backboard is 95 °, between the upper, middle and lower of the vertical side plate of described backrest frame, seamlessly transits.Adopt said structure, be convenient to the demoulding, the human design of more fitting, takes more comfortable safer.
The lateral surface cross-distribution of above-mentioned backrest frame has reinforced rib.Adopt said structure, reinforced rib has further increased the stress intensity of backrest frame.
Above-mentioned backrest backboard is provided with annex mounting hole.Adopt said structure, annex mounting hole is provided with tension steel wire and articulates.
Above-mentioned backrest frame is provided with air bag mounting hole.Adopt said structure, air bag mounting hole is for fixing seat cushion etc.
Above-mentioned front demoulding mouth is one to two, and described rear demoulding mouth is two to four.The proposition of this scheme, is not increasing headrest tube length, when saving material to greatest extent, more firm while making to coordinate between head rest pole and headrest tube.
Above-mentioned backrest frame, backrest backboard, flange and headrest tube are magnesium alloy material, and described backrest frame, backrest backboard, flange and headrest tube are one-body molded.Adopt above scheme, magnesium alloy quality is lighter, compared to traditional backrest frames, can reach 48.8% loss of weight ratio.
Beneficial effect: the car seat back frame that adopts above technical scheme, increased the intensity of seat back-rest framework, the weight of the increase backrest frames of exceeding, improved backrest frames service life, the disposable demoulding of energy on headrest tube, make releasing process more simple and reliable, can save manpower and the energy cost of demoulding link; Simultaneously because there being the existence of front demoulding mouth and rear demoulding mouth, meeting under the prerequisite of the mechanical strength coordinating between head rest pole and headrest tube, saved raw MAT'L, further reduced cost.
