As shown in figure 1 to figure 13, the utility model discloses a kind of car seat back frame structure, it uses closed
Circular tube structure, formed by the single bending of pipe 10.Pipe 10 includes headrest guide rod 11 and back bracket region 12, by guide rod of resting the head on
11 are connected with backrest lock stent area 12 by the way of welding is flattened so that the two ends of pipe 10 are directly welded at pipe 10
Pipe frame on.
Here closed circular tube structure is used, and the structure that the connected mode connect is welded with using the draw can avoid multiple zero
In the problem of part overlaps back and forth, such as Fig. 1 shown in region g and region f.In this structure, single bending circular pipe is simple into structure
Single, number of parts is few, and intensity is higher compared with bridging arrangement.
Processing is connected by the way of welding is flattened with backrest lock stent area in headrest guide rod, can be caused simple in construction
Other supplementary structures need not be increased, intensity is also accordingly lifted, such as region a in Fig. 1, region b, region c, region d, region e and
Shown in the h of region.Longitudinal pipe part A of 60% car seat back frame two ends overlap joint simultaneously directly welds with pipe part B
Connect in succession, reinforced pipe mount structure lifting overall skeleton intensity.
Preferably, guide rod 11 of resting the head on is circular arc.Meanwhile the car seat back frame structure also includes headrest conduit
30 and metal plate support 20, metal plate support 20 is welded on to the sidepiece of headrest guide rod 11, headrest conduit 30 is welded on metal plate support 20
With the top of headrest guide rod 11, support is provided to headrest conduit 30 by metal plate support 20.
Especially, headrest conduit 30 herein includes internals 32 and outer member 31, and internals 32 are nested in outer member 31, from interior
The top of part 32 to the bottom edge of outer member 31 is in a headrest inclination angle C, and the inclination angle C that rests the head on is adjustable.This headrest inclination angle
C can be adjusted the angle with backrest according to the actual needs for resting the head on angle, i.e., according to interior outer member and pipe angle adjustment head
Rest the head on inclination angle C.For example, headrest inclination angle C is preferably 10 degree.
Offer a perforate 33, center to the bottom of outer member 31 of perforate 33 respectively on the two sides of outer member 31
The distance H1 at edge is adjustable.This distance H1 can be sized according to the needs of actual height of headrest.In addition, outer member
31 top to the top distance of internals 32 is H2, can open a grade size according to being actually needed between change outer member 31 and internals 32
(i.e. distance H2), different size (i.e. H1) is obtained, so as to improve bending.
Here the side of metal plate support 20 is in circular arc, and the circular arc of metal plate support 20 and the circle of headrest guide rod 11
Arc matches fitting.
In the prior art, if three headrest features of arrangement in the split type skeletons of the 40%-60% of rear backrest, it will usually face
The problem of facing insufficient space (especially chair headrest pitch requirements are in 150mm), such as：The reduction at bending circular pipe angle then faces curved
Folding is that pipe is broken into risk.Headrest tube loses enough supports if bending angle increase is met into technological requirement, stress of resting the head on
Impact failure risk is very high.Therefore, currently without finding similar structures.
In consideration of it, headrest tube envisaged underneath one metal plate support 20 of the utility model in circular arc.So support can be direct
Welded with pipe to adapt to globoidal structure, support is provided to headrest tube, it is ensured that the stability of headrest stress impact (avoids stress from turning round
Song deformation).There is the support pipe bending angle there are enough spaces to meet production requirement, stamping parts is simple in construction, cost is low
It is honest and clean, be readily produced.Meanwhile the support can carry out respective change according to different structure.
In addition, the car seat back frame structure also includes rear backrest lock support 60, rear backrest lock support 60 is welded
It is connected on backrest lock stent area 12.The support front end of backrest lock stent area 12 is extended with a plane 61.
Rear backrest lock support 60 is sandwiched in the pipe design flattened, and soldering is done on both sides respectively, simple in construction without increasing
Extra auxiliary component is added to reduce the complexity of skeleton.In addition, a plane is extended with support front end provides support to backrest lock, from
And backrest lock stress destruction is avoided, so as to play the protective effect to lock.
Further, the punching press section increase that the vehicle body rotating shaft 40 of the car seat back frame structure connects is strengthened
Muscle, it is provided with stamping parts back side pipe junction at three and welds 41.The stamping parts section increase reinforcement being connected with vehicle body rotating shaft
Design, avoid facing intensity deficiency stress deformation directly, weld, meet at stamping parts back side pipe junction increase by three in terms of welding
Strength demand.
Further, the skeleton upper end of the car seat back frame structure is provided with some steel wires 50, for supporting
Backrest foam, really whole chair cladding outward appearance is consistent by guarantor, does not collapse.The skeleton lower end of the car seat back frame structure is provided with
Some steel wires 50, for supporting backrest foam, really whole chair cladding outward appearance is consistent by guarantor, does not collapse.Steel wire 50 herein includes short
Supporting steel wire 52 and longitudinal backrest steel wire 53, short supporting steel wire 52 are Z-shaped plane steel wire.
Horizontal backrest steel wire Uniting, share up and down, be simple in construction, reducing part category reduces skeleton complexity,
Such as in Fig. 7 shown in steel wire 51.
The upper and lower of Z-shaped plane steel wire is a kind of size design (spacing between upper and lower steel wire 50 is different), and technique simply (is kept away
Exempt from the waste of material of shape of chinese word Ji steel wire) it is beneficial to reduce production cost.
Longitudinal 53 1, backrest steel wire is dual-purpose, extends respectively both can support passenger's backrest up and down, again as foaming supporting steel
The reinforcer of silk, unitary design Stability Analysis of Structures, reduces part category and cost is cheap.
Described according to said structure, adjustment pipe size is adapted to different vehicle body environment, according to handrail width and head
Rest the head on catheter type and adapt to different design requirements.Support can design camber peace face according to the difference of welding interface
Shape, it can separately be adjusted accordingly according to the length and width and weld size of headrest tube to adapt to different types of headrest.
In summary, the utility model car seat back frame structure can reduce exploitation, production cost, part light weight
Change design, simplify structure, can solve the problem that split type skeleton three rest the head on arrangement space deficiency the problem of.The motor vehicle seat back bone
Frame structure uses closed circular tube structure, and the structure of the connected mode connect is welded with using the draw, so as to avoid multiple parts from
The problem of returning overlap joint.This structure has many advantages, such as, such as single bending circular pipe, into simple in construction, number of parts is few, and
Intensity is higher compared with bridging arrangement.
Although the foregoing describing specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
These are merely illustrative of, and the scope of protection of the utility model is defined by the appended claims.Those skilled in the art
Member can make numerous variations or repair to these embodiments on the premise of without departing substantially from principle of the present utility model and essence
Change, but these changes and modification each fall within the scope of protection of the utility model.
