Technical field
The present invention relates to a kind of backrest frame of skeleton of the back of seat that becomes automotive sheet, say so in further detail about a kind of backrest frame, it is configured to, the main composition of periphery skeleton that becomes the employed conventional seat back frame of various vehicles by use is as framework essential structure body, and with the combination of general-duty standard construction body and this framework essential structure body and carry out integratedly, in any vehicle, all realize taking a seat the raising of performance thus.
Background technology
As shown in figure 10, the structure of front-row seats of vehicle (driver's seat and co-pilot seat) 40 is, back of seat 43 tiltably is installed in the rearward end of the seat cushion 41 that occupant H sat by adjustment for angle of inclination 42, and headrest 44 is installed in the upper end of this back of seat 43.
Fig. 9 is the block diagram of expression as the general structure of the seat frame 45 of the skeleton of above-mentioned front-row seats 40.This seat frame 45 is made up of the seat cushion framework 46 of the skeleton of the seat cushion 41 that becomes Figure 10 and the backrest frame 47 that becomes the skeleton of back of seat 43.Above-mentioned seat cushion framework 46 has: left side body side frame 48 and right side body side frame 49, and with configuration, observe from front side F and to exist the compartment of terrain to be arranged side by side in parallel to each other in left and right sides L-Ri direction along the fore-and-aft direction FR of automobile; Front cross rail 50 and after cross member 51 with respect to these two body side frames 48,49, are erected between the F side end of its place ahead respectively and between the R side end of rear, both ends of the surface separately fix by methods such as welding; And constitute and overlook tetragonal frame-like.
And back frame 47 constitutes, and possesses: upper frame 52 bends to roughly reverse U shape with metal tube and forms; Be attached at a pair of left side and the right side lateral bracket 53,54 at the both ends of this upper frame 52; The bottom crossing frame 55 that reinforcement is used, with near the configuration between the position lower end separately that is erected at these two lateral brackets 53,54, both ends are fixed by methods such as welding; Steel wire 56 sets up near the position upper end separately that is installed in two lateral brackets 53,54; Four S springs 57 are tangled with the configuration between the centre portion that is erected at two lateral brackets 53,54 respectively, absorb the impact that relaxes from the place ahead.And, on the top of upper frame 52, by being welded with two headrest installation brackets 58 of the headrest 44 that Figure 10 is installed.In addition, there is the situation that replaces above-mentioned S spring 57 to use back cushion (コ Application one マ Star ト) in the difference according to vehicle.
But, in front-row seats 40 in the past, owing to for example exist cost to reduce and, therefore exist majority to be difficult to be called and take a seat well behaved seat to all constraints in the manufacturing of the parts universalization of each vehicle etc.For example, under backrest frame 47 situation for the headrest separation type of headrest 44 that miscellaneous part as shown in Figure 10 is installed, there is following seat, i.e. frame height H till the upper end that the headrest installation bracket 58 of upper frame (perhaps not being all upper beam according to vehicle) 52 is fixed
F2, compared some shortcomings with the required minimal height dimension of performance that takes a seat that acquisition is good.At this frame height H
F2In the not enough backrest frame 47, because by the installation site of headrest installation bracket 58 44 the setting height(from bottom) that determined to rest the head on, therefore become sometimes to make and take a seat the major reason that performance obviously reduces.In addition, for example, taking place under the situation about being knocked into the back, when back of seat 43 hypsokinesis, because therefore the deficiency of above-mentioned height dimension can not limit the waist of occupant H reliably to head by the back car.
And the S spring 57 and the steel wire 56 of occupant's holding components as backrest frame 47 shown in Figure 9 even its installation site and structure are extremely accurately set and installed, also are difficult to occupant H is continued to remain reliably the posture that takes a seat of hope.That is to say, as shown in figure 10, people's spine H
sBe side-looking S word curve-like, therefore from the viewpoint of ergonomics, need while taking a bus occupant H is remained on the following posture that takes a seat, promptly the spine Hs of occupant H is maintained side-looking S word curve-like always.But, because above-mentioned S spring and steel wire 56 have elasticity, thus the load of the vibration when being subjected to running car etc. always be out of shape, even so to studying in its installation site and structure, also be difficult to occupant H is continued to remain on the above-mentioned posture that takes a seat.
And, in backrest frame 47 in the past, the support property of important left and right directions in the dynamic evaluation when travelling, two lateral brackets 53,54 more from the not enough substantially seat of S spring 57 outstanding length D2 (Figure 10) forwards.In the lateral bracket 53,54 of this outstanding length D2 deficiency,, therefore occupant's spine Hs and muscle on every side thereof are brought pressure owing to can not suppress the dislocation and the vibration of the upper body of occupant H reliably.Therefore, the following back of seat of motion was also arranged in the past, promptly, by making being shaped as of the state that covers it of liner install with to(for) two lateral brackets 53,54, its part is by harder component set-up and forwards outstanding, supplies above-mentioned outstanding length D2 in shortage of lateral bracket 53,54 thus.But in the structure of the side support property that obtains the left and right sides by this liner, along with the load of bearing repeatedly from occupant H, liner is out of shape gradually, is difficult to continue to keep the support property of needs.
And, in above-mentioned backrest frame 47, when the fatigue owing to long-duration driving makes the posture of occupant H begin to change,, do not keep occupant H so can't make the ideal at the initial stage that sets take a seat posture owing to adopt occupant's holding components of elastic deformations such as S spring 57 and steel wire 56 with changing.
On the other hand, under the situation of having found the unfavorable condition that takes a seat performance as described above, also carried out following trial, for example, the raising that needs shape that installation has every kind of styling design takes a seat the accessory plate that performance is used, perhaps in the sports type automobile, as among Fig. 9 with shown in the long and two-short dash line like that, both sides at backrest frame 47 come installation side to support steel wire 59 by welding, thereby revise.But, in this modification method that every kind of vehicle is provided with special-purpose correcting part, have the problem that needs long period and cost also to increase before the exploitation.

Back of seat 14 with structure of Fig. 5 A travels car when knocking into the back being subjected to the rear, because the inertia of its collision, from occupant H the plate body 7 of standard specification tectosome 3A and center support 4 are applied the load that it is rearward moved, thus, shown in Fig. 5 D, side mounted panel 7b, the 7c of the center plate 7a of plate body 7 and the left and right sides are subjected to above-mentioned load and rearward move.At this moment, because the lateral bracket 53,54 of the left and right sides is linked on the seat cushion framework by adjustment for angle of inclination, thus only a little rearward topple over, and rearward do not move.Therefore, side mounted panel 7b, the 7c of both sides are, seat cushion distance member 19 is inboard and rearward mobile from lateral bracket 53,54 disengagings, front part deflection lateral bracket 53,54, at this moment owing to be slidably connected to the leading section of lateral bracket 53,54 and be subjected to the inside pressing force, therefore, shown in the arrow of Fig. 5 D, to the state distortion crooked to the inside with respect to center plate 7a.
Above-mentioned side mounted panel 7b, the 7c of the left and right sides of distortion to the inside, performance to occupant H from about the function that retrains with wrapping into and protect.Therefore, side mounted panel 7b, the 7c of the left and right sides, except the side support property of the dislocation of the upper body that can guarantee fully to suppress above-mentioned occupant H when travelling usually and vibration, also have concurrently when knocking into the back from about constraint and protect occupant's function.
And, when side impact takes place, in the back of seat 14 of the conventional state of Fig. 6 A, for example, under the situation of shown in Fig. 6 B, being collided from forward observation from the left side, owing to pass through impact from the automobile of this collision, via liner 17 and seat cushion distance member 19, the first half of the left side side mounted panel 7b of plate body 7 is applied load, therefore, shown in the arrow of Fig. 6 B, left side side mounted panel 7b is to the state distortion crooked to the inside with respect to center plate 7a.The left side side mounted panel 7b that this is out of shape to the inside encases occupant H ground and retrains and protect, and because the elasticity that left side side mounted panel 7b is had by itself absorbs the impact that collides vehicle, therefore can reduce the injury to occupant H.
In the above-described embodiment the situation by bottom linking method and top linking method framework essential structure body 2 and standard specification tectosome 3A, 3B is illustrated, the bottom linking method is fixed installation bracket 10 and bottom crossing frame 55 by bolt of rear end plate, the top linking method with about base pipe 4a, 4b (perhaps 9A, 9B) be welded on the upper frame 52, but when carrying out this binding, also can use other method.For example, shown in Fig. 7 A～Fig. 7 B, use is crooked with the both ends of steel wire and extension that form hook portion 20a, 20b ends parts 20, this extension is ended parts 20 to be leaned against on the upper back of upper frame 52, and hook portion 20a, the 20b at two ends are hung on left and right sides base pipe 4a, the 4b with the state of reeling from the rear, and this each hook portion 20a, 20b be welded on the upper frame 52, and fix by its junction surface 21.In this top linking method, with about base pipe 4a, 4b and upper frame 52 directly the situations of welding compare, anchoring strength improves.
And,, use the resinous connecting piece 22,23 shown in Fig. 8 A～Fig. 8 B difference as other top linking method.The connecting piece 22 of Fig. 8 A is, an end and the other end at a belt body form anticreep oral area 22a respectively and block the only 22b of tooth portion, and make card end the 22b of tooth portion with the state of reeling to insert and lead to anticreep oral area 22a, so that 2 positions up and down of base pipe 4a, 4b and upper frame 52 are linked, afterwards by blocking only the 22b of tooth portion, thus base pipe 4a, 4b and upper frame 52 are fixed as the state of mutual constraint along the direction pulling of pulling out from anticreep oral area 22a.
